摘要： A heat exchanger mounted on an air condition is constructed such that at least one row of heat conduction pipe groups are arranged across an air passage. Each heat conduction pipe groups is constructed such that a plurality of heat conduction pipes 22 are arranged in parallel with each other and a fine wire 23 made of a metallic material having excellent heat conductivity is spirally wound around each adjacent heat conduction pipes 22. Thus, performances of the heat exchanger can be improved without a possibility that the air conditioner is designed with larger dimensions. In addition, the heat exchanger includes a plurality of heat conduction pipes 39 arranged in the form of at least one row with a constant distance between adjacent ones and a plurality of twisted wires 40. The twisted wires 40 are arranged so as to alternately come in contact with one side and opposite side of each heat conduction pipe 39 extending at a right angle relative to the row direction of each heat conduction pipe 39, and moreover, alternately come in contact with one side and opposite other side of each heat conduction pipe 39 extending in the longitudinal direction. With this construction, high heat conductivity can be realized, and an occurrence of clogging with dew droplets can be prevented while maintaining a heat conduction area.

摘要： A multiroom air conditioner has a plurality of indoor heat exchangers connected to a single outdoor heat exchanger. A reversible expansion valve is installed on a liquid-side branch pipe for each of the indoor heat exchangers, and a solenoid valve is installed on a gas-side branch pipe for each indoor heat exchanger. Temperature sensors are provided on the liquid-side branch pipes, on the gas-side branch pipes, and on the outlet side during cooling of the outdoor heat exchanger. A pressure sensor or a temperature sensor detects the saturation temperature on the high-pressure side of the compressor. Based on the saturation temperature on the high-pressure side of the compressor, the temperature on the outlet side during cooling of the outdoor heat exchanger, and the temperatures in the liquidside branch pipes, a controller controls the expansion valves so as to obtain a target degree of subcooling during cooling and heating. The controller can also control the expansion valves so that the temperatures in each of the branch pipes are approximately equal to one another.

摘要： A product obtained by granulating an enzyme powder must avoid emitting dust, possess high strength, exhibit the property of quickly dissolving in water where such ready solution is necessary for the intended application, defy absorption of moisture or deformation for a long time, and preserve without a sacrifice of activity. The method of this invention produces granules of raw enzyme powder possessed of the qualities mentioned above by admixing the enzyme powder with polyethylene glycol or polyoxyethylene-polyoxypropylene block polymer of specific quality as a binder and granulating by agitating the resulting combination at a temperature not lower than the melting point of the binder. This method is suitable for production of enzyme-containing granules for use in detergents, medicines, etc.

摘要： A process and system for producing tantalum or other valve metal particles is provided comprising forming tantalum particles in a reduction process carried out in a reactor vessel, and using a siphon to transfer fine tantalum particles out of the reaction mixture to a recovery vessel. This particle transfer can occur while the reaction mixture is agitated. The tantalum particles can be automatically withdrawn when the reaction mixture has a depth level greater than the fluid level of the tantalum fine particle recovery vessel, and outflow automatically stops when the fluid levels of the reactor and particle recovery vessel equilibrate. Tantalum or other valve metal powders made by the processes, and capacitors made with valve metal powders are also provided.
