Title: Device and method for magneto-optical recording and reproducing
Inventor: OTOGAWA MITSUHIRO
IPC: G11B11/105
Filed: 1989-03-09
Abstract: PURPOSE:To reduce the size of an arrow-feather type 'tail' of a recording pit and to prevent the decrease in C/N in spite of the execution of high density recording by intentionally reducing laser power at the time of switching a data pulse to execute recording. CONSTITUTION:When a discharge pulse impressed on a laser output adjusting circuit 10 goes 'HIGH' by an Ex-OR circuit 18, a transistor (TR) 16 is turned on through a protection resistor 19 and electric charge charged to a capacitor 14 is discharged through a resistor (R) 215. Thereby, the terminal voltage of the capacitor 14 is dropped and the laser power is also dropped by the drop of a laser control voltage. When the discharge pulse is turned to 'LOW', the TR 16 is turned off, electric charge is applied to the terminal of the capacitor 14 again, a voltage value corresponding to objective power can be obtained, and the laser power is restored to the original state. Consequently, the arrow- feather type 'tail' of the recording pit due to a magnetic domain pattern can be reduced and the CN ratio can be improved.

Title: Testing system for integrated circuit element
Inventor: MAKI MAMORU
IPC: G01R31/319
Filed: 1981-04-13
Abstract: PURPOSE:To obtain an LSI testing system which tests the devices to be measured at optimum periods in follow up to the device characteristics by synchronizing the testing periods of input patterns with the response time of the devices to be measured or the delay time of internal elements. CONSTITUTION:An input pattern and an expectation pattern are transmitted from a pattern generating circuit 5, and the information for modulating the input pulses and expectation waveform is transmitted from a timing generating circuit 6. From these outputs, the input pulse waveform is made in an input pulse modulating circuit 4 and is applied to the input of a device 2 to be measured via a driver circuit 3. The output of the device 2 is converted to logical levels by voltage comparators 8, and these are compared with the expectation waveform by a coincidence detecting circuit 9. The comparison is carried out with all of the output pins, and when all the pins coincide, a signal is generated with a trigger signal generating circuit 11, and the waveform of the next pattern is formed. Thereby, the tests are carried out always optimum test periods in accordance with the variances in the devices to be measured.

Title: Acoustic diaphragm
Inventor: UEDA RIYUUHEI
IPC: H04R7/02
Filed: 1982-04-02
Abstract: PURPOSE:To allow both internal loss and modulus of elasticity of an acoustic diaphragm are compatible at a high level by mixing crystalline polyolefin resin, vinyl acetate resin, and a flaky filler, and molds. CONSTITUTION:The crystalline polyolefin resin uses, for example, polyethylene, polypropylrene, and polybutene of about >25% crystallinity. Then, vinyl acetate resin uses a <25% crystallinity material. For example, polyvinyl acetate copolymer resins consisting of about 25-100wt% vinyl acetate are usable in addition to polyvinyl acetate. The flaky filler uses mica perferably, but glass flake, talc, etc., are used upon occasion. Those three components are mixed and molded to increase the internal loss of the acoustic diaphragm while holding high modulus of elasticity. Namely, the internal loss and modulus of elasticity of the acoustic diaphragm are compatible at a high level.

Abstract: PURPOSE:To prevent a motor driving an axis B from being driven rapidly, at the application of power supply, by providing a phase discriminator, an input switching device and a phase modulator in the driving system of one axis two drive motor type. CONSTITUTION:If the position of the axes A, B of the drive motors 12, 13 is shifted from the beginning, its error component is inputted to the phase discriminator as a phase difference between an output of the phase modulator 5 and an output of a position detector 7.

When the error correction signal 2 is interrupted, a drive amplifier is operated, the drive motors 12, 13 are stopped, and the axes A, B are disconnected. When the phase of the output of the phase modulator 17 is shifted, the drive motor 13 is driven and the axis B is driven.

Title: Regulating circuit and discharge control method thereof
Inventor: GOLLA CARLA
IPC: G11C16/14
Filed: 1995-02-21
Abstract: PURPOSE: To prevent the occurrence of erase and change of contents of non- specified memory cells by providing a normally-open switch and a current generator to control a discharge current. CONSTITUTION: A memory cell 5 to be erased is specified. For performing the erasing, a programming voltage Vpp from a logical switch SW is connected to the cell to set a source line SRC a high voltage a normally-open switch 11 of control transistors M2 and M3 and an erase transistor M4. After completion of the erase stage, the line SRC has an erase voltage value higher than the high potential, which voltage is discharged to the ground. This causes a signal SL to be set at its high level, thus turning a switch I1 ON. This causes the voltage of the line SRC to be controlled by a current IS to continue slow discharging operation. In this way, since the discharging operation of the source line SRC is controlled to be gradually slow, the occurrence of erase/change of contents of the memory cells 5 other than the specified cell can be prevented.
