Title: Circulating water cooler
Inventor: NISHINO YASUO
IPC: F25D17/02
Filed: 1987-10-05
Abstract: PURPOSE: To eliminate the need of priming operation at the time of starting by branching the piping at the outlet of a circulation pump disposed below the water level when a water tank is filled with water and opening the branch pipe at a position higher than a pump in the water tank. CONSTITUTION: At the time of replacing water in a water tank 7, a refrigeration cycle and a circulation pump 8 are stopped and a solenoid valve 11 is opened. When the water tank 7 is drained under that state, the pump 8 is also drained and replaced by the air. Since a branch pipe is opened 12 into the tank 7 at a position higher than the installing position of the pump 8, the air in the pump is released by an amount corresponding to the increased water level through a water supply pipe 9, a branch pipe 10, a solenoid valve 11 and the opening 12 of branch pipe when water is supplied to the tank 7 and the pump 8 is entirely filled with water. When the water level reaches the opening 12, the air release port is blocked and the water level rises only on the water tank side.  More specifically, the pump is filled with water at the time of water supply without requiring any special priming operation and water can be supplied immediately upon starting the pump.

Title: Synthesized quartz glass and its production
Inventor: KUZUU SHIN
IPC: G03F1/60
Filed: 1990-09-21
Abstract: PURPOSE:To effectively prevent production of absorption and light emitting band at specified wavelengths for the synthesis of quartz glass by using an oxyhydrogen flame with excess hydrogen to specify the concn. of oxygen dissolved in glass and treating the glass by heating to decrease the number of specified chemical structures. CONSTITUTION:In the process of synthesis of quartz glass by hydrolysis of SiCl4 in an oxyhydrogen flame, an excess amt. of hydrogen than the stoichiometric proportion of oxygen and hydrogen is incorporated into the oxyhydrogen flame so that the molecular concn. of O2 dissolved in the glass becomes <=1X10<17> pieces/cm<3>. By this method, structural defect in the synthetic quartz glass due to oxygen can be reduced, which prevents generation of absorption band at 260nm and red light emitting band at 650nm wavelength. Moreover, the quartz glass is treated by heating in a nonreductive atmosphere or in vacuum at 200-1200 deg.C to decrease the structure expressed by identicalSi-H, H-O-Siidentical to <=1X10<18> pieces/cm<3>. Thereby, precursors of E' center can be eliminated, which perfectly prevents generation of absorption band at 220nm and light- emitting band at 280nm wavelength. Thus, quartz glass which is essentially stable can be obtained.
