A heat exchanger with a receiver tank is provided with a multi-flow type heat-exchange body (10), a receiver tank (3), a block flange (4) having a side surface connected to the periphery of a condensing portion outlet of the heat exchanger body (10) and an upper end to which a lower end of the receiver tank (3) is attached and a bracket (6) for supporting the upper part of the receiver tank (3) to the heat exchanger body (10). A flange-shaped pressing stepped portion (31a) is formed on the upper periphery of the tank main body (31) of the receiver tank (3). The bracket (6) is provided with a joint portion (61b) to be secured to the peripheral surface of one of headers (11) and embracing portions (61a) and (62a) that surround the periphery of the tank main body (31) and are engaged with the upper side of the pressing stepped portion (31a) to downwardly press the receiver tank (3). With this heat exchanger, stable refrigeration performance can be obtained and that the assembling operation can be performed easily.

The present invention relates to an inflatable intragastric balloon (1) for the treatment of obesity, intended to be implanted in the stomach of a patient, thereby reducing the volume of the stomach. Said balloon (1) comprises at least one flexible bag (2) having opposite inner side (2A) and outer side (2B), such that said inner side (2A) and outer side (2B) form at least one flexible bag ( 2), the balloon is characterized in that at least a part of said surface (2A, 2B) is covered by a coating (6, 6') made of parylene. The intragastric balloon is used to treat obesity.

A roll-top shield for weighing scales including a stationary hood 11 and a rotatable hood 12, both being made of a transparent material. Right and left side walls of the rotatable hood 12 are rotatably secured to right and left side wall of the stationary hood 11, respectively by means of pins 13a and 13b, respectively extending in the horizontal direction. By rotating the rotatable hood 12 over the stationary hood 11, an opening having a large size can be obtained, and a large or elongated article can be easily put on and off a weighing dish of a weighing device through the opening. When the rotatable hood is stopped at any desired position between a closed position and an open position without holding by hand, the opening having a desired size can be obtained, while both hands of a user are free.

The invention provides an electronic device. The electronic device comprises a shell, an input unit, a first sound hole part, a second sound hole part and a sounding unit, wherein the shell is provided with a first surface, a second surface and a third surface; the second surface is connected with the first surface and the third surface; the first surface is opposite to the third surface; the first sound hole part is arranged on the first surface; the second sound hole part is arranged on the second surface; the input unit is arranged on the third surface; the sounding unit is arranged in the front shell, and sound waves emitted by the sounding unit pass through the shell through the first sound hole part and the second sound hole part. According to the electronic device with the first sound hole part and the second sound hole part provided by the invention, the sound waves emitted by the sounding unit arranged in the shell permeate to the outside through the first sound hole part and the second sound hole part at the same time, so that sufficient volume can be supplied to a user by the electronic device; moreover, the surface of a setting input module is not occupied by the sound hole parts.

The invention relates to rotary kilns on a dry cement production line, in particular to a rotary kiln system capable of incinerating a junked tire. The rotary kiln system comprises tire conveying equipment and a rotary kiln, a first feeding scraper-trough conveyer is arranged below a conveying terminal of the tire conveying equipment, a lower scraper-trough conveyer opening of the first feeding scraper-trough conveyer is connected with a feeding port of a power-driven triple air blockage valve, a discharge port of the power-driven triple air blockage valve is connected with a feeding port of a pneumatic gate valve, a discharge port of the pneumatic gate valve is connected with an upper scraper-trough conveyer opening of a second feeding scraper-trough conveyer, a lower scraper-trough conveyer opening of the second feeding scraper-trough conveyer is connected with a feed-end chamber of the rotary kiln, and a feeding point on the feed-end chamber is located at the position enabling the tire to exactly fall in the center of the rotary kiln. According to the system, material conveying can be carried out by adjusting conveying speed and weight metering, hot air losses and exhaust emissions generated when the junked tire enters the kiln can be avoided, the fed tire can exactly fall in the center of the kiln, combustion time and combustion temperature are guaranteed, and it is guaranteed that the ash content of the tire after combustion is fully mixed and reacts with materials in the kiln.

A heat isolation cover device improving the energy efficiency of a water storage type electric water heater comprises a heat isolation cover body arranged in the inner container wall. One side of theinner container wall is provided with an inner container opening. The heat isolation cover body comprises a body incomplete column face, an end face of the end, away from the inner container opening,of the body incomplete column face, and a small complete column face close to one end of the inner container opening. An opening is formed in the lower portion of the body incomplete column face. A water outlet pipe, a magnesium bar and a water inlet pipe of the water heater can penetrate the opening of the body incomplete column face; through separation of cold water and hot water in a water heater inner container, effective hot flow management on the interior of the water heater is achieved, heat resistance of heat dissipation of hot water in the inner container is increased, the average temperature of the water at the part directly making contact with the inner container is reduced, accordingly, heat dissipation losses are reduced, and energy consumption and the energy consumption coefficient of the water heater are reduced.
