IPC: F24D19/10
Filed: 1981-04-30
Abstract: PURPOSE:To improve the hot water supplying efficiency of the titled device by a method wherein a constant temperature changeover valve is fixed to a hot water supply port provided in  water passages to be heated by solar heat while the valve is located within a heat collecting  casing so that the starting and stoppage of hot water supply are effected in response to the  variation of the temperature of the hot water in the water passages. CONSTITUTION:A heat collecting plate 11 housed within the heat collecting casing 10 is provided with a plurality of rows of water passages arranged in the vertical direction and headers  13 and 13' are provided on both ends of the water passages. The header 13 is connected to a  water supply system while the header 13' is connected to a hot water supply system through  the hot water supply port 14. In this case, the constant temperature changeover valve 15 is  fixed to the hot water supply port 14 while the valve is located in the heat collecting casing  12. The changeover valve 15 operates such that when the temperature of the water in the  water passages 12 reaches a predetermined value, a piston 21 of the valve projects due to the  expansion of a heat sensitive material 23 within a sealed vessel 22 so that a valve plate 24 is  separated from a mouthpiece 25 to thereby start a hot water supply. Further, when the temperature of the hot water falls down to a predetermined value and so the heat sensitive material  23 contracts, the valve plate 24 is brought into contact with the mouthpiece 25 to thereby stop  the hot water supply.

IPC: H02M7/48
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To enable an equipment controller to return a faulty system to a normal state without stopping equipment even when the controller performs processing in a short computing period, by transferring a plurality of blocks to the faulty system from a normal system over a plurality of computing periods in the order of dependence from the highest order. SOLUTION: When an arithmetic module 131 detects a fault in a computing period (k+1), the module 131 resets a CPU 32O and starts initralization of the control constants of registers in a RAM 316, a memory 412, and a control circuit and initialization of the other elements and the control circuit 414. During the initialization, the module 131 first checks its own hardware for faults in accordance with its own diagnostic program and whether or not a similar fault is detected during a fixed period of time in the past. When a hardware fault is detected or when it is discriminated that an unfixable fault is detected, the module 131 stops the initialization by discriminating that the fault is unfixable. When the cause of the fault is not able to be found, the initialization of such hardware as the register, etc., is started.

IPC: H04N5/235
Filed: 1988-03-18
Abstract: PURPOSE:To make unnecessary a changeover means required for the setting light receiving element exclusively used for dimming or a means to switch an image pick-up optical system at the time of executing normal photometry and at the time of dimming by correcting diaphragm information by information from a means to select the field image pick-up system or the frame image pick-up system of an image pick-up means and controlling the diaphragm of the optical system. CONSTITUTION:A control circuit 11 sets a diaphragm value information transmitted from a lighting device 16 through a line (g) at a diaphragm value at the time of using an EF mode (flash image pick-up mode) as it is at the time of using the field image pick-up mode by the information of a mode switching circuit 8, and when the mode switching circuit 8 is set in the frame image pick-up mode, the diaphragm value information transmitted from the lighting device 16 through the line (g) is shift- setted to the side of a release by 1EV. Thus, when a set sensitivity and a set diaphragm in the lighting device 16 are the same both at the time of using the field and the frame, the light emitting quantities of the lighting device 16 are the same. However, by opening one step of the diaphragm value of the image pick-up optical system at the time of using the frame to at the time of using the field on the side of a camera which receives the set diaphragm value, a proper exposure can be obtained.

Filed: 1985-03-30
Abstract: PURPOSE:To increase the withstanding voltage of an input protective circuit by forming a protective film to the lower section of a contacting section at a first step between a conductive layer constituting the input protective circuit and an input terminal. CONSTITUTION:When forming a polycrystalline silicon film pattern 27, the decrease of the film thickness of field oxide films 25 can be prevented when etching an arbitrary oxide film such as a first thermal oxide film 26. Consequently, the thick film thickness of the field oxide film 25 in the lower section of a contacting section at a first step between an input terminal and a resistance wiring 29 can be maintained. Accordingly, field strength in the field oxide film 25 in the region can be reduced, thus obviating a breakdown phenomenon, then increasing input protective withstanding voltage.
