The invention discloses a cefaclor capsule and a preparation method thereof. The preparation is obtained by mixing a cefaclor inclusion complex and pharmaceutically acceptable auxiliary materials. The preparation method of the cefaclor inclusion complex comprises the following steps: dissolving polyvinyl alcohol-polyethylene glycol grafted copolymer (Kollicoat IR) in ethyl alcohol, adding cefaclor, carrying out reduced-pressure drying for removing ethyl alcohol while stirring, and filing into capsules, thus obtaining the cefaclor capsules. The cefaclor capsule is good in stability, high in dissolve-out speed, simple in production technique, and suitable for industrial production.

The present invention relates to an andrographolide soft capsule and its production method. Every soft capsule contains 10-300 mg of andrographolide, and contains beeswax and medicinal auxiliary material. Said medicinal auxiliary material includes diluting agent, suspension adjuvant and defoaming agent, and the interior of said capsule shell, contains (by weight ratio) 10 portions of gelatin and 4.0-5.5 portions of glycerine. Its production process includes the following steps: adding water to dissolve gelatin, adding glycerine and proper quantity of preservative, vacuum deaerating, adding suspension adjuvant into vegetable oil, mixing andrographolide, diluting agent and defoaming agent uniformly, die-pressing to obtain said invented soft capsule. Its quality is stable, administration is convenient and its effective components can be quickly resolved out.

The invention discloses a moisture-proof safety power box capable of automatically removing moisture in a humid area. The moisture-proof safety power box comprises a protective roof cover, a ventilation fan, a power box body, a box door, a moisture-removing base and a protection board. The power box body is locked to the back side of a top end of the moisture-removing base, the box door is fastened to the front end of the power box body, and the protective roof cover is locked to the top end of the power box body. When the moisture-proof safety power box is used, whether the inside of a deviceis damp can be detected through a set adsorption device, when the adsorption capacity of the detection adsorption device provided by the device reaches a certain level, a heater of the device is driven to be switched on to run such that the inside of the device is dried by hot air, and the danger of short circuit due to damp and electrical conduction of the device can be prevented; when the device drives the heater to run, an air intake filtering device is lowered, the device can filter the moisture of intake air and discharge of the moisture of the intake air, therefore, the influence of external moisture on the device can be avoided well, and the device is convenient to use.

The invention discloses a protection device for transportation and conveying of precise electronic products. The device comprises a protection box body and a protection sealing cover, the protection sealing cover is located above the protection box body, the four corners of the top of the protection box body are correspondingly provided with vertically-arranged fixing grooves, the four corners ofthe bottom of the protection sealing cover are connected with fixing pins which are vertically arranged through bolts, the bottom ends of the fixing pins are inserted into the fixing grooves, and handles are hinged to the two sides of the top of the protection sealing cover. According to the protection device, transportation and conveying workers can push the protection device to move, so that thetransportation and conveying of the precise electronic products are facilitated, the labor force is saved, meanwhile, the working efficiency is improved, first springs and second springs are used forfixing the protection box body and the protection sealing cover, first memory sponge cushion, second memory sponge cushion, buffer blocks, the first springs and the second springs can eliminate the vibration and shaking of the precise electronic products in the transportation and conveying process, so that a good protection effect is achieved, and unnecessary economic loss is avoided.

The invention belongs to the technical field of a mahjong machine and relates to a multi-contact control mechanism of a full-automatic mahjong machine. The multi-contact control mechanism of the full-automatic mahjong machine solves the technical problems that in the traditional scheme, the operation and the use of buttons are not convenient enough, the sensitivity is lower, the working stability is worse and the like. The multi-contact control mechanism of the full-automatic mahjong machine comprises a control circuit board, wherein the control circuit board is provided with a button trigger area, buttons are arranged at the upper position of the button trigger area, at least two top compression columns are arranged on each button, at least two trigger points are arranged on the button trigger area and are arranged in parallel, and the top compression columns are in corresponding arrangement with the trigger points and are positioned right above the trigger points. The multi-contact control mechanism of the full-automatic mahjong machine, disclosed by the invention, has the advantages that: 1, due to the adoption of multi-contact control, the sensitivity of control cannot be affected even the sizes of the buttons are larger, the operation convenience and the working sensitivity are compatible, and the service life is long; 2, due to the adoption of a hexagonal skirt rim, the button trigger area can be effectively protected, and the influence of dust and moist is avoided; 3, due to the arrangement of notches and guiding columns, the buttons can be stably lifted and the like.

The invention provides a metal vacuum insulated panel which comprises a shell, core materials and vacuum chambers. The metal vacuum insulated panel is characterized in that the shell is a metal panel or a metal composite panel. The core materials are located in the vacuum chambers formed by welding the shell in a sealing mode and provide additional strength for the shell, so that smoothness of the shell under atmospheric pressure is guaranteed. The vacuum chambers are massively automatically welded and sealed in a vacuum furnace under high vacuum and high temperature. A preparation method of the metal vacuum insulated panel is simple in process, the prepared metal vacuum insulated panel can overcome the defects of an existing heat preserving panel and an existing vacuum insulated panel, therefore, air tightness of the vacuum chambers of the metal vacuum insulated panel can be effectively guaranteed, the service life of the metal vacuum insulated panel is prolonged, strength can be increased, and the heat insulation, sound insulation and fireproof performance and the decorative function can be increased.
