Title: Control circuit powder supply of camera
Inventor: SHIOZAWA KAZUO
IPC: G03B17/42
Filed: 1981-06-26
Abstract: PURPOSE:To prevent the control of a camera, which has plural loads and plural power sources, from malfunctioning by providing a switching means between the power sources and control circuit, and supplying electric power to the control circuit from a power source with a less voltage drop without exception. CONSTITUTION:When a motor M1 is driven, the voltage of a power source B1 drops below the minimum normal-operation securing voltage of a control circuit CC, so a transistor (TR) T2 for power source switching is turned on before the dropping and a TRT1 is turned off to switch the power source B1 to a power source B2. When a motor M2 is driven, on the other hand, the power source B2 is switched to the power source B1. The switching of the power sources for the control circuit CC is performed through control terminals OP1 and OP2 according to a prescribed program incorporated in the control circuit CC. Therefore, electric power having higher than the minimum voltage is supplied to the control circuit invariably, eliminating malfunction.

Title: Controller for thyristor-controlled motor
Inventor: MINAMI YOUTAROU
IPC: H02P6/08
Filed: 1980-07-18
Abstract: PURPOSE:To suppress a rush current at resupplying by decreasing a current phase- lead angle of a thyristor commutator at detecting a no-current state between a power supply source and a motor and also by controlling a current phase lead angle at redetecting a current after detection of no-current. CONSTITUTION:When a voltage VDC of a DC supply source E is interrupted due to some cause, an input current IAC to a motor is also interrupted, so a fact that the source E is cut off is detected by means of an AC commutator 5 and a no-current detecor 4. At this moment, a gate control circuit 7 diminishes a current phase lead angle alpha and a voltage VPN between P and N is enlarged as far as possible to maintain a clamping state. When the VDC of DC source E is recovered following this, the clamping state of a phase shifter 6 is released. Therefore, alpha is varied until IAC is ready for flowing with equivalance of VDC and VPN to suppress a rush current, and IAC starts flowing at the state that VPN is kept at its possible highest value.

Abstract: PROBLEM TO BE SOLVED: To evenly stabilize ground, by reducing the injection flow rate of a chemical grout when an absolute value of the variation rate with the passage of time in the injection pressure of the chemical grout exceeds a specified value. SOLUTION: A pump 20 is driven by a controller 40 and a chemical grout 7 in a chemical grout tank 30 is injected from an injection valve 6 of an injection outer pipe 5A into the ground 1 through a seal grout 3. The infection pressure of the chemical grout 7 is measured by an injection pressure detector 11. And The signal is input into a pressure measuring device 19 through a cable 15. The device 19 measures the change with the passage of time in the injection pressure and outputs the value to the controller 40. When cracks have arisen in the ground 1, the injection pressure is instantaneously decreased and the variation rate is abruptly changed from the positive side to the negative side.  The controller 40 regulates the pump 20 so that the injection volume of the grout 7 is reduced to a specified flow rate, when the absolute value of the variation rate with the passage of time in the injection pressure exceeds a preset specified value.
