Inventor: HIRASHIMA MITSUHIRO
IPC: G06F12/16
Filed: 1986-07-31
Abstract: PURPOSE:To assure the continuity of a memory space in terms of software by converting the address data outputted from a CPU to the address data set beforehand and outputting the converted address data when a defect exists at the memory corresponding to the address data outputted from the CPU. CONSTITUTION:The address data outputted from a CPU 1 are converted to the address data (converting value) set beforehand, and only when the defect exists at the memory corresponding to the address data outputted from the CPU 1, the address-converted address data are outputted.

Filed: 1985-08-19
Abstract: PURPOSE:To reliably close a main valve, by providing a timer for continuing a closed condition of the main valve for a predetermined period of time by an actuator after closing of the main valve. CONSTITUTION:It is detected by a closing operation of a limit switch 29a that a main valve 3 has been closed, and the closed condition of the main valve is indicated by lighting up a valve closing indicator lamp 30a provided at a control center or the like. After closing of the main valve, a solenoid 17a is excited for t seconds set by a timer 27 to continue the closed condition. Accordingly, even after closing of the main valve 3, a right cylinder chamber 18c is supplied with air from an air piping 10. As a result, a piston 18b is urged in a direction of an arrow X2 continuously after closing of the main valve to continue to drive an operation handle 3a of the main valve 3 in a valve opening direction. Thus, although an operational force of the operation handle 3a just before closing of the main valve is large, the main valve 3 is continuously closed for a predetermined period of time, thereby ensuring the closed condition.

Filed: 1992-06-15
Abstract: PURPOSE:To realize a still picture holding mode with existent circuit configuration by closing a transfer gate circuit and accessing a memory with the count operation of an address counter for serial input port. CONSTITUTION:When no write transfer inhibit signal WTD is outputted from a still picture holding mode setting part 14, normal data write and reload operations are performed completely similarly as heterofore.
