Description

Technical Field

[0001] The present invention relates to an ozone gas ejection toothbrush device.

Background Art

[0002] The use of ozone O3 has been experimentally started in many dental hospitals in recent years because of its strong bactericidal power due to O3→O2+O↑. For example, the use of O3 in a toothbrush is that although O3 gas is difficult to dissolve in water, there is a water pick using O3 water. This is to inject O3 water with a concentration of 100 to 200 ppm at the time of manufacture from a fine nozzle into the teeth and gingival pockets with a depth of 1 to 4 mm between the teeth in the oral cavity, and it is said that the bactericidal effect on the periodontal tissue and the cariogenic bacteria: mutans and lactobacillus bacteria in saliva are reduced. However, since the 100 to 200 ppm concentration of O3 in the injection into the oral cavity decreases to 1 to 2 ppm in a short time from the injection, the bactericidal effect on the periodontal bacteria and cariogenic bacteria in saliva by O3 water is significantly reduced.

[0003] On the other hand, there is a commercially available ultrasonic toothbrush with 18,000 cycles. However, although there is somewhat an effect of scraping out the periodontal pathogenic bacteria in plaque during 3 to 5 minutes of toothbrushing with the ultrasonic toothbrush, it does not reach the bactericidal action.

[0004] <Regarding Periodontal Disease> There is data saying that 70% of the Japanese population has periodontal disease. It is 6.9% for healthy people and 25% for people without 20 teeth. Periodontal disease is a bacterial infectious disease in which periodontal pathogenic bacteria in dental plaque (dental calculus) cause inflammation in the gums and gradually destroy the surrounding tissues. Since it progresses without any subjective symptoms such as pain, it is also called silent diseases, and when the symptoms progress, it dissolves the bone (alveolar bone) that supports the teeth, and eventually becomes the cause of tooth loss. It is to know how important it is to brush the teeth thoroughly throughout the oral cavity.

[0005] <Reference Information> The feature of ozone therapy is that it doesn't hurt. For tooth decay and the like, it's okay to spray strong ozone gas at a maximum of 200 ppm by holding your breath for 10 to 20 seconds (for the therapy method). Moreover, it only requires using an ultrasonic toothbrush that emits ozone gas at 0.01 to 0.05 ppm per day. As an individual, after brushing your teeth, you only need to hold your breath and spray about 20 ppm of ozone into your mouth. Start at 5 ppm for the first time.

[0006] It's impossible to completely sterilize the bacteria in the mouth. There are good bacteria, bad bacteria, and opportunistic bacteria in the human body, which are the same in the mouth and in the abdomen. Even with strong ozone, it's impossible to remove all bacteria and make it sterile. Even if it's weak (0.01 - 0.05 ppm), brushing your teeth 4 to 5 times a day is also effective enough. By replenishing sufficient moisture and making saliva flow, it's possible to clean the mouth. This is because of the bactericidal effect of saliva.

[0007] To increase the good bacteria in the mouth and maintain the best oral flora, it's necessary to have dental care to remove dental plaque once or twice a year. Basically, it's brushing your teeth. Our 0.01 - 0.05 ppm toothbrushing is to reduce the number of cleanings at the dental hospital. It's said that there are about 10 billion bacteria living in the mouth, including "good bacteria", "bad bacteria", and "opportunistic bacteria". When the balance of the oral flora is disrupted, the bad bacteria increase, causing bad breath and increasing the risk of tooth decay and periodontal disease. The balance between good bacteria and bad bacteria is said to be "9 to 1". Basically, it's thorough toothbrushing. During meals, it goes without saying, but keep saliva flowing constantly. Outside of meals, chew gum or the like to promote saliva flow.

[0008] The unexpected relationship between the intestines and saliva is that the immunity of the intestines and the quality of saliva are improved together. "Intestinal immunity" and "oral salivary glands" are linked. Therefore, when intestinal immunity is strongly improved, it creates a constitution that is less likely to get colds, influenza, pneumonia, etc. When the "amount" of saliva increases, the function of oral cleaning is strong. Saliva secretion decreases with age. The mouth becomes prone to dryness, leading to bacterial growth and bad breath. Drink water constantly. Saliva is active 24 hours a day, 365 days a year, without a single day off. Therefore, to keep the mouth clean, wash away food debris and bacteria, and have the self-cleaning function in the mouth, a decrease in saliva is likely to cause periodontal disease.

[0009] Although it goes without saying that saliva is in the mouth, we don't know deeply how it is produced. Blood is produced in the bone marrow, and that blood is transformed into saliva in the salivary glands, and about 1 to 1.5 liters of it is produced per day. It is produced in large amounts especially during meals, and decreases at bedtime. Therefore, it is necessary to brush teeth thoroughly before going to bed. Including wisdom teeth, there are 32 teeth in total, but many people have 4 teeth extracted, and how difficult it was to keep 20 out of 28 teeth until the age of 80? Ordinary toothbrushing is due to growing up with toothpaste, and the best method, dental implants, is out of pocket and very expensive.

[0010] Dental plaque (dental calculus) is not food debris, but a mass of bacteria. The number of bacteria in 1 mg of dental plaque is said to be about 1 billion. Inside the plaque, there are bacteria such as periodontal bacteria and periodontal pathogens crowded together. It cannot be removed by brushing teeth once, but can be removed at the dentist. Our 0.01 - 0.05 ppm ozone becomes a weak alkali in the mouth where oxygen is generated from O3 → O2 + O↑ by the generator. Moreover, it reacts with saliva in the mouth to generate H2O → (OH) + H↑, generating hydroxy (OH). Therefore, it has the effect of dissolving the bacteria in this dental calculus. Therefore, brushing teeth 5 times every 3 to 5 minutes also has a bleaching effect, creating a constitution where dental plaque is not easily attached. And the bactericidal power of (OH) shows a stronger reaction than ozone.

[0011] Periodontal pathogens are bacteria that dislike oxygen (anaerobic bacteria), etc. Therefore, it is difficult for oxygen to enter the periodontal pocket, so it is a favorable condition pocket. They settle in the pocket, form colonies, and gradually cause periodontal disease as they endure. These periodontal pathogens produce toxins, not allowing good bacteria to attach at all, becoming a one-sided victory and exacerbating periodontitis. The bacterium (F. n bacterium) that acts as a mastermind in promoting the growth of periodontal bacteria has been spotlighted. The F. n bacterium inhabits all sites such as our saliva, periodontal plaque, tongue, and oral mucosa.

Summary of the Invention

Problems to be Solved by the Invention

[0013] Now, as described above, although the use of O3 gas in a toothbrush has a strong bactericidal power, since it decomposes into O2 + O↑ in a short time, if the concentration and amount can be properly controlled, it is considered that the treatment effect of periodontal disease due to the long-term maintenance of the bactericidal power is great. However, to achieve this, the development of a simple O3 generator and a toothbrush that enable the generation of a trace amount of O3 and a long delay in the decomposition time is necessary. In addition, ozone therapy is a treatment that sterilizes cariogenic bacteria and periodontal bacteria and improves the balance with the resident bacteria in the oral cavity due to the high bactericidal power of ozone, which is said to be 7 times that of chlorine. However, there is no existing toothbrush that precisely controls 0.01 - 0.05 ppm of O3 to directly come out of the toothbrush. The present invention provides an ozone gas ejection toothbrush device that combines a simple trace concentration O3 generator and an O3 ejection toothbrush to solve this problem.

Means for Solving the Problems

[0014] The technical features of the present invention for solving the above problems are as described in the following (1). (1) Deposit and coat two types of metals, Cr + W, Ti + W, Cr + Mo, or Ti + Mo, on the surface and / or inner surface of the quartz pipe, and further perform a fused baking coating of CuB. An ejector is provided on the air intake side of the quartz pipe 308, and a magnet placement chamber for a neodymium magnet is provided on the outlet side. (Also referred to as the following electromagnetic magnetic field generator) An ozone generator incorporating a quartz pipe type discharge tube provided with a magnet placement chamber for a neodymium magnet on the outlet side and an ejector on the air intake side, and ozone gas O3 from the ozone generator is introduced into the inside of the toothbrush and ejected from ejection holes provided in the head of the toothbrush. Neck An ozone gas ejection toothbrush device characterized by comprising an ultrasonic toothbrush incorporating an ultrasonic oscillator.

Effects of the Invention

[0015] Even if you combine using a dental rinse or a gingival brush to develop the habit of not forming periodontal plaque (dental plaque) or use fluoride-containing toothpaste for brushing, it is very difficult to completely remove the bacteria in dental plaque. It is difficult for it to completely enter the 0.1 - 0.5% gap between the gums that support the teeth. The oxygen of the generated radicals when O3 decomposes into O2 + O acts simultaneously for bleaching and sterilization. And ozone emulsified by strong vibration of 18,000 Hz deeply penetrates. Such an effect has never existed before. There is a toothbrush that emits hydrogen gas by decomposing hydrogen gas (He) water. Although it claims to have the effect of producing (OH), it cannot produce an emulsion manually at 100%. We emit ozone gas of 0.01 - 0.05 ppm from an 18,000 Hz ultrasonic toothbrush and produce an emulsion with saliva.

[0016] Ozone of O3 with a concentration of 0.01 - 0.02 - 0.03 ppm as the main output is a circuit with a double fuse-like resistance of 0.01A - 0.03A in a super-dense design of a high-frequency circuit. Through experiments with resistance inserted, success was achieved after many attempts. Although it is simple, 0.01A breaks instantly. Backup is impossible during operation. When it reaches max 800 ppm, a resistance of max 10Ω is required. The circuit design for this difference was very difficult, but the present invention is the first to successfully generate optimal effective low-concentration ozone within the Japanese regulations.

[0017] The ozone gas ejection toothbrush device of the present invention generates appropriate trace amounts and concentrations of O3 by the ozone generation device and supplies it to the ultrasonic toothbrush, so it has a great therapeutic effect on periodontal disease by maintaining the bactericidal power for a long time. That is, it is an ozone gas ejection toothbrush device that combines a simple device that enables the generation of trace amounts of O3 and a long delay in the decomposition time with an O3 ejection toothbrush with a simple structure.

[0018] That is, the ozone gas ejection toothbrush device of the present invention continuously supplies O3 gas with a concentration of 0.01 to 0.05 ppm from the aforementioned ultrasonic toothbrush into the oral cavity during brushing, so that the saliva in the oral cavity becomes an emulsion state and delays the decomposition of O3. For this reason, a much greater bactericidal effect can be obtained than when the oral cavity is periodontally washed with the aforementioned O3 water. In addition, in this ultrasonic toothbrush, the periodontal bacteria in the plaque that causes periodontal disease are efficiently scraped out by injecting O3 gas of 0.01 to 0.05 ppm, which advantageously prevents the occurrence of periodontal disease.

Embodiments for Carrying Out the Invention

[0020] Next, embodiments of the present invention will be specifically and detailedly described with reference to FIGS. 1 to 5.

Example

[0021] In FIGS. 1 to 5, the ozone gas ejection toothbrush device comprises a known toothbrush body 100 and an ozone generator 300 for supplying O3 gas to the toothbrush body 100. The ozone gas ejection toothbrush device of this example directly and continuously supplies ozone gas at 0.01 to 0.05 ppm continuously for 3 to 5 minutes of brushing time from the ozone generator 300 into the 18000-cycle vibration ultrasonic toothbrush body 100, so that the "spit" solution in the mouth becomes an emulsion state, delaying the decomposition of ozone, scraping out the periodontal bacteria in plaque that causes periodontal disease during brushing, and efficiently sterilizing various bacteria in the oral cavity to prevent periodontal disease. Furthermore, in addition to ejecting ozone gas at a concentration of 0.01 to 0.05 ppm to the teeth and gums, the ultrasonic vibration hubrush 100 of this example softly applies ultrasonic vibration to the teeth, does not hurt the gums, and sterilizes oral bacteria such as periodontal bacteria while maintaining the oral cavity well, thereby maintaining the healthy state of the oral cavity over a long period.

[0022] Thus, the toothbrush body 100 introduces ozone gas from the O3 supply pipe of the ozone generator 300 through an O3 gas introduction socket 200 provided between the upper end of the handle portion 101 and the lower portion of the neck cover 102, and ejects it from between the bristles 105 of the head 104 or from ejection holes 106 provided in the upper portion of the neck cover 102 in the vicinity thereof.

[0023] As shown in FIG. 3, the toothbrush body 100 is integrally formed with a neck vibration core 103 on the upper portion of the handle portion 101. The neck vibration core 103 is accommodated in the neck cover 102 and incorporates an ultrasonic vibrator 106 therein. The neck cover 102 is detachably fitted and connected to the lower portion of the neck vibration core 103. This fitting connection is achieved by a fitting convex protrusion 103-1 of the neck vibration core 103 and a receiving recess 102-1 at the lower portion of the neck cover 102 with a toothbrush. Also, an O3 gas introduction socket 200 shown in the plan view and front view of Fig. 4(3) is connected between the lower end of the neck vibration core 103 and the lower end of the neck cover 102 with a toothbrush. The O3 gas introduction socket 200 has a receiving metal 202 made of NiCr plating silver-soldered to the ring part 201, and the O3 gas introduction hole 203 of the receiving metal 202 is connected to the O3 gas supply pipe 301 of the ozone generator 300 to receive O3 gas and introduce it into the toothbrush body 100. The O3 gas introduced into the toothbrush body 100 from the O3 gas introduction socket 200 flows within a gap of 0.1 mm between the surface tapered surface of the neck vibration core 103 and the inner surface tapered surface of the neck cover 102 with a toothbrush, and jets out from the jet outlet 204 provided at the neck of the upper end of the neck cover 102 with a toothbrush at a position directly below the head 104. The ultrasonic oscillator 107 transmits and vibrates the ultrasonic vibration of 18,000 cycles to the bristles 105 of the head 104 through the neck vibration core 103 and the neck cover 102 with a toothbrush.

[0024] The ozone generator 300 can change the ozone generation amount to 0.01 - 0.05 ppm, 200 - 400 ppm, and 400 - 800 ppm according to the purpose. Although the appropriate ozone gas concentration for the human body is determined by law to be 0.01 - 0.05 ppm, the ozone generator 300 of this example clears this. The feature of this ozone generator 300 is an ozone generator using a quartz pipe discharge tube 307, and the main components are composed of a battery 301, a control panel and timer condition setter 302, a high-frequency power supply 303, a control PC 304, an air pump 305, and a quartz pipe discharge tube 307 as shown in Figs. 2 - 3. (When used indoors, with a 100v changeover switch)

[0025] As shown in Fig. 5, the quartz pipe discharge tube 307 is configured such that a Cu-plated Cu + P spring pipe 309 that closely adheres to the inner wall of the quartz pipe 308 is closely attached inside a quartz pipe 308 (outer diameter 15 mm × inner diameter 13 mm × length 38 mm) with a Cu foil or a steel wall wound around its outer tube, aiming to extend the service life of the high-frequency power supply 303, and it is a method of continuously generating a large current that breaks the insulation of air. As a countermeasure against the thermal expansion of air, even if the speed is increased by the electromagnetic magnetization machine 311, magnetization of O3 ensures that the concentration is maintained at 0.02 - 0.03 ppm outside a hose with an outer diameter of 6 mm × inner diameter of 4 mm × maximum length of 10 m. The Cu-P spring pipe 309 has such a strong spring force that it is also called a Cu spring steel, so it adheres 100% inside the quartz pipe 308 and high-frequency electricity flows stably.

[0026] For the quartz pipe discharge tube 307, an ejector 306 is installed at the air inlet to increase the inlet air by about 30% for cooling the heating by high voltage, which also increases the generation amount of O3. At the outlet, an electromagnetic magnetization machine 311 with a total of 9000 - 9800 G neodymium magnets 310 arranged is connected, and passing O3 through it delays the decomposition of O3. As a result, although the half-life of O3 is 16 hours, due to the thin ozone O3 at 0.01 - 0.02 PPM / h, it is strongly retained.

[0027] The ejector 306 is such that the air inside the quartz pipe 308 is instantaneously destroyed and energized at high temperature and high pressure, generating O3. In the conventional single-pipe type, the air that is instantaneously destroyed and expanded has a pressure increase of 30% or more. Therefore, the air intake side adopts a method of covering the required amount of air to withstand the 30% expansion pressure in the ejector 306 method. Moreover, since the expansion pressure leads to an increase in speed, an electromagnetic magnetization machine 311 with neodymium magnets 310 arranged to receive primary air is installed on the outlet side to suppress the decomposition of O3. The electromagnetic magnetization machine 311, which is the secondary chamber, is entirely within a magnetic flux of 9000 G. Since the half-life of O3 is as short as 16 hours, in order to slow down the decomposition of the weak ozone O3 for 3 - 5 minutes of operation and 15 - 20 minutes of rest operation, which is within the Japanese safety standard of 0.01 - 0.05 ppm in the atmosphere, electromagnetic release is performed.

[0028] Furthermore, on the surface and / or inner surface of the quartz pipe 308 of the quartz pipe discharge tube 307, two kinds of metals, Cr + W, or Ti + W, or Cr + Mo, or Ti + Mo are vapor-deposited and coated by the API method, and further CuB is melt-baked and coated. Thus, the ozone generator 300 can change the O3 concentration according to the purpose within the ranges of 0.01 to 0.05 ppm, 200 to 400 ppm, and 400 to 800 ppm by the control PC 304. Although the appropriate ozone gas concentration for the human body is legally determined to be 0.01 to 0.05 ppm, since this is cleared, the ozone generator 300 can change the ozone generation amount according to the purpose within the ranges of 0.01 to 0.05 ppm, 200 to 400 ppm, and 400 to 800 ppm.

[0029] In the ozone generator 300, the measurable concentration with an ultra-precise measuring instrument with a maximum of 3.5 ppm was as low as 0.016 ppm of ultra-trace ozone. Fortunately, this was experimented by myself, let alone an experiment in the mouth. I myself, the monitor, experimented with 4 periodontal diseases. As a result, there were no teeth to be extracted in December last year, and the remaining teeth are gradually becoming healthy teeth. Ozone therapy has been carried out in Sweden, Germany, and Japan for more than 15 years. Ozone generators that can be ultra-precisely controlled are very expensive and difficult to realize. This was the factor that prevented it from being applied to personal toothbrushing.

[0030] The teeth received from parents are said to cost 2 million yen each. Implant treatment is also said to cost 450,000 yen ± 10%. Retaining 20 teeth at the age of 80 cannot be achieved by brushing teeth 3 to 4 times a day. It is necessary to visit the dentist once or twice a year for plaque removal. The inventors manufactured an ozone generator at low cost, and it has now become possible for personal use.

[0031] Since the surface of the quartz pipe type discharge tube 307 is subjected to AIP vacuum deposition and the inner surface is CuB-plated with a glaze close to enamel, it is possible to purify ozone gas with various concentrations in the range from trace to 800 ppm max.

[0032] <W, Mo AIP Vacuum Evaporation on the Surface of the Quartz Pipe 308 of the Quartz Pipe Type Discharge Tube 307> Since there are up to 6% uneven fine particles of W and Mo on the surface of the quartz pipe 308 due to vacuum evaporation by AIP, large, medium, and small electric discharges occur, so the O3 concentration can be controlled from 0.01 ppm to 800 ppm. The vacuum hardening film of AIP mainly forms a hardening layer. Mainly, with ion particles in N2 gas, TiN, TiAlN, TiCN, CrN, ZrCrN have been the coatings so far and were the targets. A new target of the two types of ion metals was made and experimented by ionizing two types of W ions with an area ratio of 6.3% in the Cr 100% target simultaneously with about 94% Cr and about 6% W and depositing them on the quartz pipe. Due to arc discharge, a high-density current ranging from 10 6 ~10 8 A / cm 2 is concentrated on the arc spot with a diameter of about 10 μm, generating a high temperature of 4000 - 10000 K as Joule heat and instantaneously melting and evaporating the cathode material. Refractory metals such as W (tungsten: 5555 °C) and Mo (molybdenum: 4639 °C) can also be evaporated relatively easily. This time, the uneven particle ions of Cr + W form an interesting corona discharge. The bactericidal effect of W particles has not been confirmed whether they have antibacterial properties like silver, copper, zinc, cobalt, and nickel, but when humidity is added to metal ions, a bactericidal effect appears due to the ion difference. In the literature, it is said that Cr, Mo, and Zn have antibacterial properties, so it is thought that W is due to the Cr system.

[0033] There are four types of discharges: corona discharge, glow discharge, spark discharge, and arc discharge. Ozone is generated in both corona discharge and glow discharge. When the potential difference applied between the electrodes is increased, the air existing between the electrodes undergoes dielectric breakdown and current flows. As a result, O2 → O + O → O + O2 → O3, and it reacts with 21% of the oxygen in the air to produce O3 gas. The melting points of Cr and W are nearly in a 1:2 ratio, and the number of ions with a potential difference of about 6% between them, and in a 0.1 mm thick × 35 mm long pipe-shaped Cu-P that sticks to the center, the time for coastal discharge appears about 6% later. The uneven ionization current randomizes the corona discharge, so conversely, the repeated strong and weak cycles improve the ozonation power. Also, by passing a 900 G magnetic field so that the ozone layer protects against the proton ions blown from the sun, unprecedented ozone is created.

[0034] O3 is generated by the uneven ion current. Conventionally, pipes with the same diameter holes for inlet and outlet of ozone were mainly used. Due to high heat, air expansion only increased the flow rate, and the generation of O3 was poor. Therefore, to cover nearly 30% of the expanding air, air is supplied by the Venturi tube method, and by maintaining a constant flow, the conventional maximum of 30% has been improved.

[0035] <Regarding CuB plating with a glaze similar to the enamel on the inner surface of the quartz pipe type discharge tube 203> When a simple substance of acid (H3BO3) and copper ions Cu(BF4)2, CuCl2, CuCO3, etc. are baked at 650 - 850 °C, a copper glaze can be placed on SiO2, enabling CuB plating.

[0036] 100% chemical plating cannot be applied to the SiO2 of the quartz pipe 308. Also, an expensive reducing agent like Pd is not required. By mixing boric acid (180 - 800 °C) and copper chloride (650 °C) in a 50:50 ratio of each powder and holding at MAX 700 °C for 30 minutes, heating plating was made possible. It was made into a flux-like state by simply mixing two types without using a flux, and the quartz pipe was melted and baked on this flux by the convection method. Since this method is in a state where SiO2 + H3BO3 + CuCl2 are attached, it is not a stable hot adhesion plating and has variations, but for the first time, plating was possible without using expensive AIP or CVD (heating plating).

[0037] Firing by melting was carried out only in the final process at 850 °C. Near 800 °C, CuBF4 (copper borofluoride) is used. For the etching of the quartz pipe 308, the halogens F, Cl, and Br are absolutely necessary. The combination of boric acid and CuCl2 (copper chloride), and H3BO3 (boric acid) and CuBF4 (copper borofluoride) is up to 800 °C. In the quartz pipe 308 of the ozone generating discharge tube 300, 100% plating cannot be achieved by the normal plating method. It is also impossible to deal with SiO2 even by the etching method (halogen - HF). Therefore, the AIP method was adopted, and the enamel is fired at 700 - 800 °C. It is impossible to closely adhere the Cu - P foil to the inner surface of the quartz pipe 308 using the spring force because it is as viscous as enamel. The liquid firing flux, even after being applied and fired 10 times, forms a thin film of 1 μm - 2 μm. It is important that it is a 100% liquid firing flux.

[0038] The inventor has the technology to make the speltering flux liquid as in the liquid flux of Patent No. 4736105, but it is an extremely difficult problem for SiO2. Up to H3BO3 (boric acid: 180 - 800 °C) in the heating furnace, it evaporates as a single substance, so CuCl2 (copper chloride 650 °C) is added to make it liquid. Putting these two in separate containers allows for plating to some extent through their evaporation and ionization, but it takes a long time at 850 °C, lacking in productivity.

[0039] The inventor has challenged plating on quartz (SiO2) through electroless plating for about three years, but there was no fusion without applying heat of 500 - 800 °C. Metal ions (Xn, Cu, Ni, Sn, Sb, Cr, Fe) were put into 100% halogen flux, and experiments were carried out until cyanidation (Nc) for stability. Although plating 100% was experimented with hundreds of times, it was impossible. The firing flux (a type of enamel) is 100% enamel - like. Since SiO2 can withstand up to 1800 °C, it has become a flux similar to glassy glaze. Since SiO2 can withstand up to 1800 °C, if a glaze at 600 - 800 °C is made, there is no need for expensive AIP or CVD treatment. It is a flux similar to enamel rather than a speltering flux. For 42 years, the inventor has mainly engaged in brazing at a welding rod manufacturer and developed fluxes. Therefore, it was thought that SiO2 could be tackled relatively easily. It was considered an extension of the ceramic brazing flux, but it took about three years. The biggest reason was that it was decided not to use noble metals such as Pd, Ir, Pt, and Ru as inorganic reducing catalysts. PdCl2 is used even in glass plating. Metals more expensive than gold are not used. It is possible for automotive catalysts because it costs over 30,000 yen per gram, but such expensive metals cannot be used in a device costing tens of thousands of yen. In the aforementioned (0025), although it was somewhat successful and the components are shown, since it is 100% liquid, about 10 bakings are required to make it 1 μm to 2 μm thick. For an ozone generator of the SiO2 level, copper plating is possible with such a flux.

[0040] Gold plating of the quartz pipe 308 became possible by the baking method of the liquid flux (MAX850°C), but the thickness was 1 μm after 5 bakings. It was found through about three years of electroless plating that gold plating of the quartz pipe 308 is almost 100% impossible other than by CVD and AIP, and it was vapor deposition plating by heating (700 - 800°C). The flux in the final process made as described above is baked at a maximum of 130 cc per time and at 850°C, so it gradually concentrates in the atmosphere in the vial. Since the vial has a diameter of 15 × a diameter of 13 × a length of 50 mm, when baked in the atmosphere at 850°C in the vial and rapidly cooled in the vial, the flux bakes (100°C). Since it gradually becomes thicker, it becomes 1 μm thick after 5 to 6 bakings. Due to its small size, it has not been mass-produced. This is because each reaction is random in electroless plating. It is hand-made baked plating. What is similar to enamel is baking with a gas burner at 800 - 850°C. It would be ideal if it could be done all at once 360° over the entire surface like high frequency, but there is a lack of funds. If Ar gas is injected and sealed each time the final liquid flux is applied and heated up to 850°C, copper oxide will not form, so a complete quartz pipe type discharge tube for O3 generation can be made.
