IPC: H01F27/00
Filed: 1988-01-22
Abstract: PURPOSE:To prevent malfunction, by judging whether or not the changes of oil pressure level inspected continuously are due to the increase of oil pressure caused by a trouble which has occurred in an oil-filled electric equipment after the changes of the oil pressure caused by an earthquake or the operating condition of a cooling pump are eliminated by an arithmetic unit.

A cooling pump controller 3 detects the signal informing of the operating condition of a cooling pump and a seismometer 4 detects the occurrence of an earthquake to convert into an electric signal. A microcomputer 5 processes the signals from the oil pressure inspector 2, the cooling pump controller 3, and the seismometer 4 for output. The oil pressure level in the oil-filled electric equipment is calculated from the oil pressure level inspected continuously by the oil pressure inspector 2 after eliminating the levels of the changes of the oil pressure caused by the operating condition of the cooling pump sent from the cooling pump controller 3 and the levels of the changes of the oil pressure sent from the seismometer 4. The results are sent from an output device.

Title: Positioning controller
Inventor: HIGOMURA MAKOTO
IPC: H01L21/027
Filed: 1986-01-23
Abstract: PURPOSE:To shorten positioning time and to improve positioning accuracy by permitting a speed function generator to change a speed curve, correcting a decelerating start position and controlling positioning. CONSTITUTION:If the position deviation value of a position deviation counter 4 is higher than the switching position data P of a switching position deviation register 18, an analog switch 6 is switched to a speed control side to control speed. At that time of controlling speed, a D/A converter 2 outputs a speed command voltage based on a speed curve generated by the speed function generator 1, and gives it to speed servo systems 7-9. Thus the speed curve is changed to vary the speed and position of a movable body 10. If the contents of a counter 4 agree with those of a register 18, a motor 8 begins to decelerate, and the switch 6 is switched to the position control side. At the time of the 2nd action a decelerating point start position is corrected from a correction value obtained from the 1st action. Accordingly the stop position approximates a stop target position to shorten the positioning time.

Filed: 1988-01-22
Abstract: PURPOSE:To reduce maneuver noises of the magnetometer by forming an aperture of successive magnetic bodies which have a necessary opening diameter in a plane at the part of the parallel light of a light beam perpendicularly to the optical axis. CONSTITUTION:At the part of the parallel light of the light beam, the aperture formed of the nonmagnetic bodies having the necessary opening diameter is provided in the plane perpendicular to the optical axis. For example, when the opening diameter of the aperture 15 for a counterclockwise circular polarized light system is 35mm, a magnetooptical resonance curve delta<-> shown in a figure 3a is obtained. Further, when the opening diameter of the aperture for a clockwise circular polarized light system is varied in the order of 34, 35, and 35.5mm, a magnetooptical resonance curve delta<+> is obtained to obtain a magnetooptical resonance curve graph wherein the delta<-> and delta<+> are almost axially symmetrical, and it is considered that its composite magnetooptical resonance point C is set at a nearly ideal point. Consequently, the resonance point C of the composite magnetooptical resonance curve does not vary even by the maneuver of an aircraft, etc., and the maneuver noises of the magnetometer can be reduced.
