Abstract:
Disclosed is a tap water temperature sensing type of light emitting apparatus, including: a power source 15 adapted to supply power; a control unit 30 for sensing opening/closing state of the tap tube to control the power source 15 such that if the tap tube is opened, power supply is done and if the tap tube is closed, the power supply is stopped; a sensing unit 40 disposed around a portion where hot water and cool water meet for sensing the temperature of water in the tap tube; and a light emitting unit 50 for producing different color lights in accordance with the water temperature read in the sensing unit 40.
Abstract:
Disclosed is a condensing system which can selectively provide cooperative operation of an air cooling condenser with a water cooling condenser or an evaporative condenser according to variation of ambient air temperature, coolant pressure and condensing load. The water cooling condenser is disposed between a compressor and the air cooling condenser, and includes a coolant pipe, a water passage for enabling water to flow therethrough to have heat exchange with coolant in the coolant pipe, an inlet pipe and an outlet pipe connected with the water passage of the water cooling condenser for automatically feeding and discharging water in a direction reverse to a flowing direction of coolant and a control valve installed in the inlet side of the inlet pipe for automatically controlling water feed to the water passage according to ambient air temperature, coolant pressure and condensing load. Alternatively, the evaporative condenser is disposed between the compressor and the air cooling condenser, in which the evaporative condenser is placed in the air discharge side of the air cooling condenser to evaporate moisture via air forcibly introduced by a condenser fan and coolant so that coolant can be condensed via latent heat of vaporization. Otherwise, a water pipe is selected from a middle one of chambers of coolant pipes, the coolant pipes are folded and fins are interposed between folded regions of the coolant pipes.

Abstract:
A new, pulp-like, acrylic short fiber having excellent heat- and chemical-resistance is provided. The fiber has a thickness distribution of 0.1 mu m to 50 mu m, a length distribution of 1 mm to 20 mm, and a thermal transition temperature (Tg) of above 200 DEG C. The fiber is produced by heating a mixture of polyacrylonitrile and water of about 5% to 100% by weight to temperatures above hydration-melting temperature under seal to an amorphous melt; cooling the resulting amorphous melt to temperatures between the melting and the solidifying temperatures of the melt to form a supercooled melt; extruding the resulting supercooled melt to give extrudates; heat-stabilizing the resulting extrudates at temperatures between 180 DEG C. and 300 DEG C. for 1 minute to 4 hours after drying and drawing; and cutting and beating the resulting heat-stabilized extrudates into an appropriate size.

Abstract:
A condenser for heat exchanger systems, capable of reducing a compressed refrigerant from a vapor phase to a liquid phase, is disclosed. The condenser has a condensing tube connected to a refrigerant tube located between a compressor and a capillary tube in order to allow a refrigerant in a heat exchanger system to pass through the condensing tube. Also, a liquid tube is integrally formed on a side wall of the condensing tube by an extrusion process. In addition, a radiating pipe, having a long zigzag shape, is mounted to the liquid tube in such a manner that both ends of the liquid tube are connected to a liquid supplying inlet and a drain outlet of the radiating pipe, respectively. Thus, a condensing medium in the radiating pipe is effectively circulated through the radiating pipe and the liquid tube.
