Title: Ground-fault detecting device
Inventor: FURUTA TAKU
IPC: H02H7/26
Filed: 1994-04-28
Abstract: PURPOSE:To minimize the influence of a residual current by providing a digital potentiometer which is connected to a photoelectric conversion section and actuated by a signal from a controller and a variable amplifier which is connected to the potentiometer and composed of an amplifier. CONSTITUTION:A controller calculates the effective value of a residual signal and changes the amplification factor of an R-phase variable amplifier 20 by adjusting the digital potentiometer of the amplifier 20 by transmitting a signal to the potentiometer so that the value of the residual signal can become the minimum. After changing the amplification factor of the amplifier 20, the controller again finds the residual current and calculates the effective value of the zero-phase current. The controller sets the potentiometer so that the residual current can become the minimum by repeating the above-mentioned operation several times. Then the controller minimizes the influence of the residual current by adjusting a variable antplifier 20 connected to an S-phase photocurrent sensor and another variable amplifier connected to a T-phase photocurrent sensor. By repeating this adjustment several times in the order of phase, the residual current is minimized.

The cyclic selenium is incorporated into the raw material for vapor deposition at >=75% content. The alloy 2 is melted at 400 deg.C and thereafter the temp. is decreased to 250 deg.C and the molten alloy is dropped from the nozzle 6 into pure water 7, by which the photosensitive layer having the high cyclic selenium content is formed. The decrease in the concn. after continuous and repetitive image formation is thus prevented.

Filed: 1989-05-09
Abstract: PURPOSE:To accurately measure a distance without being affected by how a camera is held nor the arrangement of a subject by dividing the light beam from a light source into three vertically and moving the light source horizontally and mechanically. CONSTITUTION:A prism 11 is arranged on the projection side of a projection lens 2 and has a surface 11A perpendicular to the optical axis of the incident light and slanting surfaces 11B and 11D. The light beam from the light source 1 is therefore split into three light beams to generate measured distances Pa, Pd, and Pb in the center and upper and lower parts in a photography range 10. Further, the light source 1 is moved by a motor in parallel to the length of a base line, so distance measurement points are formed at Pa1, Pb1, and Pd1, and Pa2, Pb2, and Pd2. Consequently, the distance measurement points are distributed in two dimensions, so the distance accurately is measured even when the camera is held longitudinally or when right and left separate subjects are arranged.
