Title: Method for initial injection of circulating water in hot water heating apparatus
Inventor: FUKUZAWA KIYOSHI
IPC: F24D3/00
Filed: 1990-02-07
Abstract: PURPOSE:To certainly judge the completion of the initial injection of heating circulated water by judging that the injection of initial circulated water is completed when the surface of a high water level is maintained even when a predetermined time is elapsed after the output signal of a water level sensor displays the high water level. CONSTITUTION:The fluctuation of the water level in a hermetically closed cistern 9 is monitored by a water level sensor 21 without setting the overflow from a drain port as the basis of judgment and a circulation pump 10 is operated without hastily deciding that the injection of water is completed only when the water level in the ustern reaches a high level to continuously monitor the tendency of the water level in the cistern by operating a circulation pump. Next, when a water level is lowered by the operation of the circulation pump 10 to become a low level, the injection of heating recirculated water is continued. Therefore, there is no possibility such that air is left in the circuit by erroneously judging the completion of injection in an excessive early stage. When the water level in the cistern is continuously held to a high level for a predetermined time, it is judged that the initial injection of heating circulated water is completed.

Abstract: PROBLEM TO BE SOLVED: To effectively prevent a vehicle fire after an accident by enclosing an airtight vessel in a part of a car body by compressively filling incombustible gas or a fire extinguisher in the airtight vessel, and discharging the inside incombustible gas or the fire extinguisher by receiving pressure not less than prescribed pressure to the airtight vessel. SOLUTION: An airtight vessel 1 filled with incombustible gas or a fire extinguisher is housed in the back part of a U-shaped bumper 6 to be fixed to the bumper 6 by a proper fixing metal fitting 10. Exhaust pipes 11, 11 are extended in the airtight vessel 1 enclosed in the bumper 6 so that these exhaust pipes 11 are introduced into an engine room.

Abstract: PURPOSE:To enable always stable image recording, by detecting the output of acousto-optical modulator which superimposes the output light of a gas laser on the image information externally given and making the gain control of the modulator so that the output can always be constant. CONSTITUTION:Since the zero-order diffracted light of the modulator 5 is proportional to the light of the primary diffracted light used actually as write-in light, the gain control of the modulation signal of the modulator 5 is made with the peak voltage according to the light amount of the zero-order diffracted light detected and stored in the peak holding circuit 16.
