Inventor: ARIMA HIDEAKI
IPC: H01L21/265
Filed: 1981-09-28
Abstract: PURPOSE:To simultaneously form regions having different film thickness by a method wherein thermal oxidation is done after implanting nitrogen or an ion including nitrogen into a silicon substrate. CONSTITUTION:A pattern is formed on a silicon substrate 1 by photoresist 4 and nitrogen or an ion including nitrogen is selectively implanted into the silicon substrate 1. Next, after removing the resist 4, thermal oxidation is applied. The nitrogen implanted at that time segregates on the silicon surface to prevent oxidation. Therefore, a difference in the oxidation speed of silicon is arisen at the region implanted nitrogen and that implanted no nitrogen and regions having different thickness of silicon oxide films 2 are simultaneously formed. Next, polycrystalline silicon films 3 are grown on the films 2 and after forming patterns, MOS gates having different thickness of silicon oxide films are simultaneously formed by using the films 3 as masks and by etching the films 2.

Title: Manufacture of multi-core superconducting wire
Inventor: TANAKA YASUZO
IPC: B21F19/00
Filed: 1988-06-22
Abstract: PURPOSE:To improve current density and to better workability by arranging polygonal element wires so that the geometrical center of gravity of the cross section of an element wire is positioned concentrically and each cross section takes the same direction to the center of the concentric circle and inserting them into a metallic pipe. CONSTITUTION:The diameter of the element wire is reduced to manufacture a rectangular wire and this rectangular wire is cut to a prescribed length to obtain an element wire. The element wires 32 are inserted into a silver pipe 42 while arranged concentrically around a silver bar 6C and reduced in diameter to obtain a round wire. In this way, since polygonal element wires are arranged isotropically to the concentric circles, this round wire is free from unshaped void and shaped voids are berried by element wires of different shapes arranged concentrically and the space factor of superconductors in the complex can be intensified. Further, since, in a compression time, an equal working strain is given on a concentrical circle, accidents such as disconnection are reduced and working yield and productivity are improved.

Title: Magnetic head
Inventor: HASEGAWA MITSUHIRO
IPC: G11B5/127
Filed: 1989-06-19
Abstract: PURPOSE:To obtain balanced floating quantity and to prevent damage to be caused by head crush by making the width of a sliding surface where a perpendicular magnetic field generating core is embedded wider than the width of a sliding surface where the core is not embedded. CONSTITUTION:A perpendicular magnetic field generating core 4 is embedded in a sliding surface 2 of a slider 1 and the width l1 of the sliding surface 2 is made wider than the width l2 of a sliding surface 3 where the core 4 is not embedded. The floating quantity of the slider is proportional to the 1/2 power of disk circumferential velocity and the 3/2 power of sliding surface width and inversely proportional to the 1/2 power of load. Accordingly, by making the width of the sliding surface 2 having a larger load wider to increase the floating quantity, floating quantity do can be made the same as the sliding surfaces 2 and 3 and a stable floating posture can be obtained. Thus, the head crush to be caused by dust, etc., can be prevented and at the time of seeking, a lowering rate of floating quantity can be reduced as well.

Title: Method for connecting communication of cordless telephone set
Inventor: OMORI TADASHI
IPC: H04W84/08
Filed: 1989-06-19
Abstract: PURPOSE:To omit channel switching and to shorten a communication established time by regarding a communication established when both base and mobile stations confirm that a control channel itself is idle in case of using the control channel at the time of starting communication. CONSTITUTION:On the base station side receiving connection request data, whether the control channel to be used at the time of receiving is idle or not is decided by a decoding part 6. When the idle control channel is decided, a control part 5 starts a switch 32 and turns off a communication channel control part, so that the communication channel is not used for a speaking channel. Then a sending circuit 3 is turned on and data informing the idle state of the control channel are transmitted from an antenna 13. On the mobile station side, the idle data of the control channel are received by an antenna 31 and decoded by a decoding part 18 through a receiving circuit 15. At that time, a switch 33 turns off a communication channel control part 26 to inhibit the transfer of the control channel to a speaker channel. Since a speaking state is started thereafter, communication can be established by using the control channel without transferring the control channel to the speaker channel.

Title: Remote adjustment device for antenna
Inventor: AKAGAWA MASATAKE
IPC: H03K17/78
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To facilitate impedance matching while an antenna is in a mount state by sending an optical signal with an object frequency from an optical signal transmission section to a reception control section of each trap of an antenna element and controlling the transmission so as to optimize an SWR value. SOLUTION: Frequency traps 150ab, 251ab are provided to an antenna element 62 and a reception control section of a remote adjustment device is provided to each trap. Furthermore, a transmitter-receiver 58 is connected to an antenna matching balun 52 of an antenna feeding part via a coaxial cable 56. In order to measure the impedance matching of the antenna feeding part, an SWR meter 57 is connected before circuit connection. Then a radio wave of an object frequency is sent from the transmitter-receiver 58 with a small power and an optical signal transmission section 63 sends an optical signal 64 of the object frequency to the reception control section of each trap, the signal is decoded and the transmission control of the optical signal 64 is conducted so as to minimize the indication of the SWR meter 57. Thus, the impedance matching is easily optimized while the antenna is mounted.

Title: Cutting method for thin belt body
Inventor: HASHIMOTO TAKASHI
IPC: B65H19/22
Filed: 1986-07-01
Abstract: PURPOSE:To cut a thin belt body in an accurate manner, by making a nip roller contact with an empty core via the thin belt body, then lowering tension of the thin belt body between the empty core and a full core more than the winding tension, and cutting the thin belt body with a cutter in a low tension state. CONSTITUTION:A nip roller 6 is made contact with an empty core 3 via a thin belt body F whereby a fact that tension acting on the thin belt body F at the upstream of the nip roller 6 will act on the thin belt body F at the downstream side of the nip roller 6 is surely cuttable. Under this state, tension of the thin belt body F at the side of a full core 3' between the empty core 3 and this fill core 3' is lowered more than the normal winding tension, and in this state, the thin belt body F is cut off by a cutter 27. In consequence, excessive tension will not act on the thin belt body F at the time of cutting, whereby the thin belt body F is smoothly cut off without being torn off. Therefore, the thin belt body F is wound on the empty core 3 in good conditions so that a changeover from the full core to the empty core is automatically performable in a smooth manner.

Abstract: PROBLEM TO BE SOLVED: To improve steering feeling without transferring the vibration by a motor such as a torque ripple to a steering wheel by controlling the steering angle with only the output of the motor driven based on the detection result of the rotation detecting means of the steering wheel. SOLUTION: The detection value of a steering wheel action detecting means 5 detecting the steering wheel action of a driver with an encoder and a torque meter is transferred to a motor control means 7 by a cable 8 to drive a motor 10 via a cable 9. A current is fed to the motor 10 based on a current detection value and a motor current target value calculated by inputting the steering wheel torque, steering wheel angle obtained from the steering wheel action detecting means 5 and vehicle speed to a motor control means 7. The steering angle of wheels 14 can be controlled by only the output of the motor 10 connected to a steering wheel 1 via the cables 8, 9 only electrically, not mechanically, thereby steering feeling can be improved without transferring the vibration such as a torque ripple generated by the motor 10 to the steering wheel 1.

Title: Power input circuit
Inventor: OKAMOTO MASAMI
IPC: G05F1/10
Filed: 1995-06-21
Abstract: PURPOSE: To prevent inrush current from flowing to a main circuit by installing a thermistor in parallel with a parallel circuit composed of a capacitor, a Zener diode and a relay. CONSTITUTION: A thermistor 9 is provided with the function of, after an AC power supply 1 is once interrupted, reducing its resistance by heating and thereby instantaneously discharging electric charge accumulated in a capacitor 8 for time constant setting that determines the rise time of a relay 3 so that the potential of the relay 3 may be reduced to reset voltage or below. That is, after the application of the AC power supply 1, the capacitor 8 for time constant setting that determines the rise time of the relay 3, is charged. When the power supply is then interrupted, the resistance of the thermistor 9 is reduced by heating. When the resistance of the thermistor 9 falls below the internal resistance of the relay 3 in parallel connection, the electric charge accumulated in the capacitor 8 is quickly discharged.  This reduces the time it takes for the potential of the relay to reach reset voltage from the rated voltage, and makes it possible to pass inrush current through an inrush current limiter resistor with reliability.
