Title: Optical reproducing device
Inventor: YAMAGUCHI HIROHISA
IPC: G11B19/10
Filed: 1981-12-10
Abstract: PURPOSE:To detect whether a sheet-like recording body is present or not through simple constitution by adding a lens forcible displacing signal circuit and a recording medium loading state detecting circuit to a focus control system. CONSTITUTION:When a switch 34 is turned on, an AND gate 22 is opened to supply a voltage from a saw-tooth wave generating circuit 23 to a moving coil 8 through a synthesizing circuit 18, so that a lens 7 is displaced gradually to an in-focus state. Light from a laser light source 3 is caused to incident a disk 1 and its reflected light is caused to incident a four-split photodetector 11 through a beam splitter 6. The difference output is supplied to the synthesizing circuit 18 and a comparator 27 through an error amplifier 12 and also supplied to a comparator 30. Those comparators 27 and 30 compares the inputs with reference voltages E1 and E2 and generate pulses, which are sent to an NOR gate 32, inverter 35, and peak holding circuit 36 to display a disk loaded state signal on a display device 37. Thus, the loading of a disk is detected by the simple constitution.

Title: Controller for stop position of motor
Inventor: KITA HIROBUMI
IPC: G05D3/12
Filed: 1986-08-27
Abstract: PURPOSE:To improve the detecting accuracy by using a sine wave encoder to constitute a speed/position detector. CONSTITUTION:A stop position controller for a motor 1 consits of a speed control circuit 2, an electric converting circuit 3, a speed detecting circuit 4, a constant position stop control circuit 12, etc., and performs the speed control based on an external speed command as well as the stop control at a fixed position. In this case, a sine wave encoder is used as a speed/position detector 6 and this encoder delivers a sine wave containing two phases A and B that have a phase difference of 90 deg. and a specific position signal (phase Z) that produces a signal of a signal pulse when a specific position is occupied by a motor shaft. Thus the detector 6 can utilize not only the frequency but the phase as the position information. Therefore the satisfactory speed/position detecting accuracy is secured despite a small output frequency set per rotation of the detector 6.

Title: Reproducing device of information record carrier
Inventor: TAKADA YUUZOU
IPC: G11B19/28
Filed: 1982-11-12
Abstract: PURPOSE:To reduce the impact force that a reproducing stylus generates to a disk when reproduction starts by lowering the reproducing stylus before the disk attains to the rotating speed of normal recording and reproduction. CONSTITUTION:When the rotating speed of the disk 6 is sufficiently low, e.g. N1, the reproducing stylus 2 starts contacting the disk and the disk attains to a specific rotating speed N0 after specific stylus force M0 is obtained. Namely, this is attained by inserting a delay circuit into another driving system depending upon which time is longer, the time that the disk takes to attain the specific rotating speed after being driven and the time that the reproducing stylus 2 takes to contact the disk after starting moving down. Thus, the impact force that the reproducing stylus exerts to the disk when reproduction is started reduced.

CONSTITUTION:The sliding plane of the slider 2 is provided with a negative pressure sliding plan 3b recessed between positive pressure sliding planes 3a and 3b and inclined front and rear edges 3c and 3d, and a head chip 5 is embedded in the plane. A side groove 3e is provided at the negative pressure sliding plane 3b, and a parallel groove 3f at the inclined plane 3c. The plane 3b, and the grooves 3e and 3f decide the floating quantity of the slider 2 at the time of rotating the magnetic disk 10. The air exhaust nozzle 6 is provided at the side of the inclined planes 3c and 3d of the sliding plane 3b. The air is exhausted from the nozzle 6 to the recording medium plane 10a of the disk until the rotating speed of the magnetic disk 10 arrives at prescribed speed, which floats the slider 2 compulsorily, and the recording plane 10a can be prevented from being damaged. After the rotating speed of the disk arrives at the prescribed speed, the exhaustion of the air is stopped, and the slider can be floated stably with the air that flows between the sliding plane 3 of the slider 2 by the rotation and the medium plane 10a. The air is also exhausted at the time of stopping the rotation of the disk, which prevents the head and the disk from being damaged similarly as when starting.

Title: Ground detection method of gas-insulated switchgear
Inventor: CHO TERUMICHI
IPC: H02B13/065
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To detect the ground by utilizing the shielding case of a current transformer and eliminate the gas ground transformer(GPT) of a gas-insulated switchgear(GIS). SOLUTION: The shielding cases 22 of the main circuit current detecting CTs of the respective phases of a GIS have capacitances C1 between the main circuit conductors 21 of the GIS and themselves respectively. The shield cases 22 of the respective phases are connected to each other with conductors 24. A voltage dividing capacitor C2 is connected between the conductors 24 and the ground and monitored. When the ground does not exist, voltage vectors generated by the capacitances C1 of the respective phases cancel each other and hence a voltage is not applied to the voltage dividing capacitor C2. If the one-line ground exists, the relations between the voltage vectors generated by the capacitors C1 of the respective phases collapse and hence a voltage is applied to the voltage dividing capacitor C2.  Therefore, the ground can be detected by monitoring the voltage of the voltage dividing capacitor C2.
