Title: Turbid liquid transferring apparatus
Inventor: BETSUPU KOUICHI
IPC: B65G53/30
Filed: 1984-06-11
Abstract: PURPOSE:To constitute a universal compact apparatus and improve the durability thereof by arranging pressure containers and increasing and reducing gas pressure supplied and exhausted to and from the containers to increase and reduce the turbid liquid pressure for transferring the turbid liquid according to the gas pressure control. CONSTITUTION:A gas supply valve 5 is opened in the boosting process to supply high pressure gas from a high pressure gas supply tower 7 to a pressure container 1 and increase the internal pressure. Then, since the pressure in the supply tower 7 is reduced, the internal pressure in the pressure container 1 is increased to pressure Pmax which is the reduced pressure minus pipe resistance. When the internal pressure in the pressure container 1 is increased to Pmax and pressures in the inlet and outlet sides of a turbid liquid exhaust valve 3 are balanced with each other, the boosting process of the turbid liquid is completed and the next liquid exhaust process is carried out. Then said valve 3 is opened and the high pressure gas is supplied to the pressure container 1 so that the turbid liquid is pumped out of the pressure container 1 through said valve 3. A highly universal compact apparatus can be constituted by said constitution to improve the durability and controllability.

Title: Method and apparatus for erasing data of optical recording medium
Inventor: TSUJIOKA TSUYOSHI
IPC: G11B7/00
Filed: 1992-05-13
Abstract: PURPOSE:To efficiently erase data by detecting data recorded in a medium and changing the intensity of beams corresponding to the signal. CONSTITUTION:A regeneration light source 3 emits regeneration beams of a semiconductor laser with relatively weak constant power, thereby to form a focus spot A onto a photochromic material 11 by an objective lens 2. The optical change of characteristics corresponding to the recording data is detected. The light projected from an erasure light source 4 forms a focus spot B on a recording layer of the medium 1 through a dichroic mirror 7 and the lens 2. The spot A is arranged precedent to the spot B on the same track. The time distance since a point, on the medium 1 passes A until the point reaches B agrees with the amount of time delay from a delay circuit 13. The intense erasure beam is cast only to a recording part on the medium 1, thereby ensuring efficient erasure and high reliability.

Abstract: PROBLEM TO BE SOLVED: To reduce noise during operation by applying a polyphase DC motor drive a sine-wave voltage at a prescribed phase, detecting zero crossing of the currents of respective windings, and adjusting the phases of drive voltages in zero-crossing at the same time. SOLUTION: A signal VMAG 24 which controls the amplitude of excitation for analog-digital input voltage and a signal PHADJ 26 for adjusting a phase command the DC phase lead adjusting between exciting and counter electromotive force. When a waveform generator 12 generates three digital outputs of UPA 40, UPA 42, and UPA 44, these signals are pulse-width modulated for driving phase drive devices 14, 16, 18. The amplitude of a sine wave is proportional to the signal VMAG 24 which controls the amplitude of output, and the timing is determined by a QVCO on a line 21 from the phase detector of a VCO circuit 20. With the speed of a pulse-width modulated motor 22, a pair of comparator are provided respectively at both ends of a drive FET, and the frequency determines the zero crossing of the sine wave voltage. The current zero crossing of the drive devices 14, 16, 18 matches with the zero crossing of sine wave drive voltage waveform in terms of time.

Title: Semiconductor switch control circuit
Inventor: HASEGAWA KOUICHI
IPC: H03K17/62
Filed: 1984-06-13
Abstract: PURPOSE:To prevent the effect on other circuits by delaying an on-control signal for a prescribed time and applying the signal to each on-gate terminal of both semiconductor switch elements respectively so as to eliminate a period when both the switch elements are turned on simultaneously at signal switching. CONSTITUTION:Suppose that a high level signal is fed to a terminal 4, then a gate turn-off transistor (TR)16 is turned on, a TR14 is turned off and a thyristor comprising TRs 12, 14 is in the off-state. On the other hand, since a gate turn-off TR15 is turned off and a TR13 are turned on, a thyristor comprising the TRs 12, 13 is in the on-state. Since a high level signal is impressed to a base of the TR14 via a delay device 9 in this state, the TR14 is turned on not momentarily but after a prescribed time. Then the thyristor comprising the TRs 12, 14 is transited to the on-state with a delay.
