Title: Automatic stop device for television camera
Inventor: KANAZAWA IZUMI
IPC: H04N5/238
Filed: 1981-05-16
Abstract: PURPOSE:To close an aperture without exception after the disconnection of a power supply, by additionally providing a capacitor charged from a power supply voltage when current is flowed and a circuit to close the aperture through the amount of charge of the capacitor at the interruption of power supply. CONSTITUTION:In a monitor TV camera, a capacitor 6 is charged with a power supply voltage from a terminal A during the usage. If the power supply is interrupted, it is detected with a circuit 7 which generates an aperture stop signal by using a photocoupler or the like, and a signal closing the aperture the same as high luminance through the charge in a cpacitor 6 is applied to a level adjusting circuit 2. Simultaneously, a backup voltage corresponding to the power supply voltage from a terminal B is applied to a level adjusting circuit 2 to keep each circuit at an operation state and the aperture wings of an aperture switching circuit 4 are rapidly driven toward the closing direction the same as at high luminance. Thus, the aperture can automatically be stopped through the interruption of the power supply in any state, allowing to minimize the deterioration of a pickup tube.

Title: Power source for arc machining
Inventor: MORIMOTO YOSHIKI
IPC: B23K9/09
Filed: 1990-03-23
Abstract: PURPOSE:To suppress the generation of the surge voltage by switching to a minimum value by providing a switching element control circuit which controls opening and closing of a switching element of a DC/AC conversion circuit in synchronization with an OFF period of time of a switching element for a chopper. CONSTITUTION:A PWM circuit 19 outputs signals s1 and s2 with the time width determined by the difference between the output Vr of an output current setter 17 and the output Vf of an output current detector. An output signal s5 of a chopper control circuit 21 falls at the last time of this signal s1 and the switching element 14 is cut off and a current thus decreases rapidly and comes near zero. A signal delay circuit 20a starts the time limit from this time and a signal s3 is turned OFF at the time after the set time limit. Consequently, although the switching element 4 is cut off, the current has already been diminished to zero by this time, hence the switching element 4 is cut off in an almost no-load state.
