Title: Range-finding device for passive type autofocusing device
Inventor: ISHIGURO MINORU
IPC: G02B7/30
Filed: 1991-02-22
Abstract: PURPOSE:To accurately and rapidly measure a distance to an object so as to surely focus on the object even in the case that plural objects exist. CONSTITUTION:The object is caught by a light receiving sensor constituted of three line sensors 10b, 20b and 30b and the zero cross point of the secondary difference of brightness distribution is operated. Whether the zero cross point is a zero cross point in the case that the secondary difference is changed from positive to negative or a zero cross point in the case that it is changed from negative to positive is detected. As for zero cross behavior concerning three line sensors 10b, 20b and 30b, one of the line sensors 10b, 20b and 30b is taken as a reference and the coincident point of three zero cross behaviors is detected by properly shifting other two line sensors. Then, the distance to the object is measured based on the deviation of the zero cross behaviors of two line sensors in the case that they are coincident.

Title: Partial discharge tester for electric equipment
Inventor: TAKAHASHI HIDEKI
IPC: G01R31/12
Filed: 1983-03-25
Abstract: PURPOSE:To prevent omission of detection signals by connecting a protection resistance in series to an output terminal of a high voltage generator and a bypass capacitor in parallel to the power source section to lower the impedance of the power source section. CONSTITUTION:A bypass capacitor 13 is connected in parallel to output terminals A and B of the power source section in which a protection resistance 3 is connected in series to a high voltage output terminal of a high voltage generator 2. The electrostatic capacitance of a bypass capacitor 13 is selected to be an equal value to the electrostatic capacitance of a connection capacitor 4. With such an arrangement, the impedance of the power source section can be lowered so that the detection sensitivity of the detection signal v3 to be detected with a detector 9 can be elevated to the equal level to the detection signal v1 to be detected with a detector 7 with respect to a partial discharge generated in a sample 1. Thus, the impedance of the power source can be lowered.

Abstract: PURPOSE:To remove jamming paper easily in safety by supporting a separating pawl turnably within a specified range to some part of a heat insulation cover which is supported turnably while its maximum rotation range is limited, and energizing the pawl in such a direction that it contacts a heat roller. CONSTITUTION:If recording paper jams between the front edge 9a of the separating pawl 9 and the peripheral surface of the heat roller 6, a unit 45 is drawn out and the heat insulation cover 22 is lifted after the cover 49 of an inverting device 30 to turn both movable parts 24b and 23b. Consequently, the separating pawl 9 supported by the movable part 23b also turns and its front edge 9a leaves the heat roller 6 to remove the jamming paper easily. In this case, the turning ranges of both movable parts are limited by allowing the projection 63 of the movable part 23b to abut on a stopper 52, preventing the danger of burn, etc. Further, the turning range of the separating pawl 9 is limited by allowing the projection part 9b of the separating pawl to abut on a stopper 65 to prevent trouble such over turning. Thus, the removal of jamming paper is performed easily in safety.
