Title: Oil pressure control device for automatic transmission
Inventor: TSUKAMOTO KAZUMASA
IPC: F16H61/06
Filed: 1994-12-02
Abstract: PURPOSE: To prevent the occurrence of suction owing to the pump action of a clutch hydraulic servo during N racing and to prevent the generation of a centrifugal oil pressure. CONSTITUTION: An oil pressure control device comprises an oil pressure source 10; a hydraulic servo; an oil passage 11; an oil passage 12 with an orifice; and an accumulator 30. The accumulator 30 is located in the oil passage 11 and the oil passage 11 is communicated and disconnected by the stroke of a piston 32. A switching means 40 to switch communication and disconnection of the oil passage 11 is placed between the accumulator 30 and the hydraulic servo. When an oil pressure fed from the oil pressure source 10 to the oil passage 11 exceeds a given value, the oil passage 11 communicates and during N racing, suction of oil from the oil passage 11 owing to the pump action of the hydraulic servo is prevented from occurring.

Title: Optical transmission method, optical transmitter and optical transmission system
Inventor: MATSUURA AKIHIKO
IPC: H04B10/61
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of waveform distortion of a modulator drive signal due to the low band cutoff characteristic of a modulator drive circuit and to raise the limit for the distance of transmission by converting the binary data signal into a deformed duo-bianry signal that is suppressed to a DC component and using this duo-binary signal as the modulator drive signal to drive a light intensity modulator. SOLUTION: A binary data signal is converted into a deformed duo-binary signal that is suppressed to a DC component and used as a modulator drive signal which drives a light intensity modulator. A deformed duo-binary coding circuit 10 converts 0 and 1 of the binary data signal into 0 and +1 or -1 respectively and also converts the binary data signal into a ternary deformed duo-binary signal of -1, 0 and +1 whose +1 and -1 are never continuous over 2 bits respectively. The ternary deformed duo-binary signal is turned into a non-inverse deformed duo-binary signal and an inverse deformed duo-binary signal whose phases are inverted to each other by an inverter circuit 75 and then applied to the electrodes 84a and 84b of an MZ type light intensity modulator 80 via the modulator drive circuits 76a and 76b respectively.

Title: Magnetic disk device
Inventor: OIZUMI YUMIKO
IPC: G11B20/10
Filed: 1989-12-21
Abstract: PURPOSE:To prevent production of a read error at a same position by providing a means storing the read error at its detection and a means storing a data in a defect alternate area when a data is written in a stored read error location. CONSTITUTION:A magnetic disk device 1 is provided with a read error location storage means 2 and a defect alternate control means 3. The means 2 is provided with a nonvolatile memory and when a read error is detected in the area, the read error is stored. Since the means 3 stores the area not in use as a defect alternate area when the means 3 writes a data to a read error stored as above, the defect alternate processing is implemented just after the read error is generated. Moreover, since the use of the area having the read error is stopped to allocate the defect alternate area automatically, the production of the read error at the same position is prevented.

Abstract: PROBLEM TO BE SOLVED: To enable a variable control of the frequency characteristic of a compression-encoded audio data to a plurality of desired frequency characteristics, and at the same time reduce the amount of calculation. SOLUTION: A compression-encoded audio data supplied from external circuit via an input terminal 1 is converted to the audio data in the frequency range through inverse quantization process by an inverse quantizing section 3 and this audio data is then supplied to a filter section 4.

Title: Information processor
Inventor: TAKEDA TOSHIHIKO
IPC: G11B9/04
Filed: 1994-12-05
Abstract: PURPOSE: To obtain an information processor in which the resolution of a probe is enhanced by a method wherein a frictional force generated at a time when the probe is scanned in a state that a probe tip has been brought close to, or brought into contact with, a medium is reduced by applying a voltage across the probe and the medium. CONSTITUTION: A reverse-potential signal from a reverse-potential-signal application means 108 is applied across a probe 101 and a medium 104 so as to offset a potential-difference signal generated across the probe 101 and the medium 104. When a potential difference generated in the generation process of dynamic friction is reduced in this manner, a frictional force which is generated across a probe tip 103 and a recording face or a sample face 105 can be reduced. As a result, the resolution of the probe and the reliability of a recording and reproducing operation can be enhanced, and the power consumption of an information processor can be reduced sharply.

On the other hand, a continuity clip 12 is formed into a shape having a wire insertion space 16. Then, the shield layers of the shield wire 1 and the grounding wire 8 to be connected with them are inserted into the wire insertion space 16. Thereafter, a spring piece 15 is pressed against a wire bundle 17 while both ends of the continuity clip 12 is held so that the small-width part of the spring piece 15 is so pressed back by its elastic force as to spring back into a bent state in the same direction as a connecting board 14 and thus, the shield layers and the grounding wire are brought into a state to catch them together.

Abstract: PURPOSE:To enable eliminating induction noise caused by transversal current, without adding a balun type transformer, by providing a core, two primary windings wound around the core, a secondary winding wound around the core, and two balun windings wound around the core. CONSTITUTION:Driving transistors 17, 18 are connected to the respective other ends of primary windings 11, 12. When the transistors are turned ON/OFF, and currents flow intermittently through the primary windings 11, 12, a detection voltage generates in a detecting winding 14, in accordance with the above currents, and this voltage is supplied to a detection circuit. In the secondary winding 13, an induced voltage generates, and this voltage is supplied to each end of balun windings 15, 16. After induction noise component caused by transversal current is eliminated by the balun windings 15, 16, the voltage generated in the secondary winding 13 is output from the other end of each of the balun windings 15, 16, and supplied to an output circuit. Since the balun windings 15, 16 are wound around the core 10 of a transformer, the induction noise caused by the longitudinal current can be reduced without adding a balun type transformer.
