Title: Optical driver
Inventor: NAKAMURA KEIJI
IPC: G02B7/09
Filed: 1985-11-28
Abstract: PURPOSE:To reduce the number of parts to simplify assembling by winding directly a tracking coil around a holder to exclude the constitution where the tracking coil holder is used to insert a yoke for tracking through the tracking coil. CONSTITUTION:Tracking coils 21a and 21b are wound on both sides of a supporting shaft of a holder 6 orthogonally to the extension of the holder 6. A desired current is applied to a focusing coil 8 or tracking coils 21a and 21b to move the holder 6, namely, an objective lens in the direction of an arrow B or A, and the objective lens in controlled in the focusing or tracking direction. The holder of this device is supported freely slidably on a supporting shaft 5 and is connected to a fixed yoke 1 with only an elastic member 11. Thus, the number of parts is small to simplify assembling, and the elastic member is removed to pull out and replace easily the holder from the supporting shaft, and the extent of operation of the holder is increased.

Abstract: PROBLEM TO BE SOLVED: To detect a cassette as to whether it is recordable or not before loading this cassette into a recording and reproducing device by detecting the recordability of the cassette under its storage state and telling a detecting result in details. SOLUTION: A photodetector 27 is moved into a place for detecting the existence of, for instance, a VTR cassette 7 by a detecting operation starting command in accordance with information of a position measuring means incorporated in a carrier 29. Then, when reflecting light of the light of a light emitting part of the detector 27 is not detected by the emitting part, no cassette is judged in a cassette rack 17. When the reflecting light is detected to Judge the cassette 7 to be in existence, the detector 27 is shifted to a place for detecting the existence of an erroneous erasing preventing piece of the cassette 7, where similarly to the judgement of the existence of the cassette, the reflecting light is detected by the detector 27 to judge recordability with the reflecting light or unrecordability with no reflecting light, and either of these judging results is told by a lamp.  This operation is performed on cassette racks 17-26, and their results are displayed by lamps, so that a stored cassette condition can be known under the storage state as it is by the operator.

Title: Fluid supply control method
Inventor: TAKESHITA KATSUHIRO
IPC: G05D7/00
Filed: 1989-10-16
Abstract: PURPOSE:To effectively prevent the one-sided increase of a supply error by studying the difference between the sum total of the integrated value of the command supply value accumulated so far up to the preceding time and the new command supply value and the integrated value of the real supply value accumulated up to the preceding time every time a new supply command is produced. CONSTITUTION:A supply command of water is produced concurrently with supply of a medicine, and a solenoid valve 11 provided to a route 10 is opened for supply of water to a liquid tank 1. The open/close of the valve 11 is controlled by a control part 13. The part 13 reads the output data on a flow rate meter 14 to integrate the water supply value and the command supply value. Then the valve 11 is kept closed when the difference between the total P of the command supply value and the integrated value Q of the real supply value is negative or equal to zero. Meanwhile the valve 11 is opened when the difference is positive so that this difference is eliminated. Thus the density of the medicine never goes beyond the expected range despite the repetitive supply of the medicine or the increase of the water supply error.

Title: Power supply for electric motor vehicle
Inventor: KOGA TAKESHI
IPC: H02J15/00
Filed: 1990-10-11
Abstract: PURPOSE:To supply power continuously through a simple constitution by a constitution wherein a superconducting energy storing means, mounted on an electric motor vehicle which is fed with power from a stringing through a current collector, is charged when the stringing is contacting with the current collector whereas it is discharged when the current collector is separated from the stringing. CONSTITUTION:A filter capacitor 9 is charged from a stringing 1 through a current collector 3, a circuit breaker 5 and a filter reactor 7 mounted on an electric motor vehicle. When current is collected normally, a load on the vehicle is fed with power from the filter capacitor 9 through a stationary power converter 11. On the other hand, a charge/discharge section 13 conducts gate turn off thyristors GTO 19, 21 to charge a superconducting coil 15 and when the current detected through a CT 17 reaches the capacity of the superconducting coil 15, one GTO 21 is made nonconductive. When the current collector separates from the stringing to cause voltage drop of the capacitor 9, the GTO 19 is also made nonconductive and the capacitor 9 is charged from the superconducting coil 15 through diodes 23, 25. Consequently, power is fed stably through a simple constitution even when power supply from the stringing 1 is interrupted temporarily.
