Title: Method and circuit for maintaining horizontal position of vibration isolating mount and for eliminating horizontal vibration thereof
Inventor: YASUDA MASASHI
IPC: F16F15/02
Filed: 1989-07-24
Abstract: PURPOSE:To maintain a horizontal position and control vibration of a vibration isolating mount irrespective of a size of a vibration frequency by adjusting a pneumatic pressure in a pneumatic spring in response to a sum of a position control value output with a difference between analog position voltage and reference position voltage calculated and a horizontal vibration control value output with horizontal analog accelerating voltage calculated. CONSTITUTION:A horizontal shift  Y of a vibration isolating mount body 2 with respect to a reference horizontal position O is sensed and output as analog position voltage. The analog position voltage is compared with reference position voltage to output the difference, which is then integrated or both integrated and amplified to have a position control signal output. At the same time, horizontal vibration acceleration Y'' of the vibration isolating mount body 2 is output as horizontal analog accelerating voltage, which is then subjected to one or two, or all of integration, differentiation and amplification to be output as a horizontal vibration control value. A pneumatic pressure in a control side pneumatic spring 3b is adjusted to respond to the sum of the position control value and the horizontal vibration control value.

Title: Electrically driven type power steering device
Inventor: SHIMIZU YASUO
IPC: B62D5/04
Filed: 1984-09-12
Abstract: PURPOSE:To prevent a motor from being frequency energized, by enlarging the width of the dead zone set to an electrically driven power steering device, with increase of a vehicle speed. CONSTITUTION:When a torque is applied externally to an input shaft 1 so that the torque is detected by a torque detecting section between input and output shafts 1, 4, an armature current is fed to a winding 23 under operation of a control circuit. Thus, a motor 18 is energized so that rotor rotates in the same direction as that of the input shaft 1. The above-mentioned control circuit subtracts a signal controlling the energizing amount of armature current from a signal corresponding to a vehicle speed to generate a dead zone proportional to the vehicle speed. As a result even if a steering torque is applied in a high speed running condition, the motor 18 will not be energized, and therefore, the steering device is operated only by manual operation.

Title: Manufacture of compound semiconductor crystal
Inventor: NISHIJIMA YOSHITO
IPC: H01L21/365
Filed: 1990-07-19
Abstract: PURPOSE:To prevent the formation of a twin CdTe crystal having a crystal growing plane in (110) plane on a substrate by using a semiconductor crystal, in which the plane having the plane azimuth of (100) plane perpendicular to (100) axis is inclined in the direction of (111) plane by a prescribed angle, as the substrate and forming a compound semiconductor crystal containing cadmium by vapor growth on the substrate. CONSTITUTION:A GaAs substrate 32 with an off-angle formed by inclining (100) crystal plane by 2 deg. in the direction of (111) plane is placed in a container 1 at a prescribed interval from a section above a source crucible 33 and thermal cleaning is performed by heating the substrate 32 to 6O0 deg.C with a heater 34 after the container 31 is evacuated to a high vacuum condition. After the heat cleaning, the substrate 32 is moved to the section above the crucible 33 by turning a substrate placing table 35 and a CdTe source in the crucible 33 is evaporated by lowering the temperature of the substrate to 350 deg.C and raising the temperature of the crucible 33 to 530 deg.C so as to allow the evaporated component of the source to adhere onto the substrate and a CdTe crystal to grow. Therefore, a high-quality CdTe crystal of (111) plane is obtained, since no (111)-plane twin crystal, the two individuals of which have crystal axes which are rotated by 90 deg. against each other, is formed on the (100)-plane GaAs substrate.

Title: Magnetic head
Inventor: SAKAKIMA HIROSHI
IPC: G11B5/127
Filed: 1987-07-31
Abstract: PURPOSE:To attain a high density recording by projecting light on one part of a superconduction magnetic shielding part, heating it, leaking a magnetic flux from a permanent magnetic part, and magnetizing a recording medium. CONSTITUTION:A magnetic part A, sort magnetic substance magnetic flux guiding parts Bi and B' are enclosed with a superconductor part C. Light beams emitted in synchronization from laser light sources E and E' are projected between B and Bi, and B' and Bi' successively from i=1 to (n) by movable mirrors F and F', by heating the light beams simultaneously with the irradiation, the magnetic flux flows in the way of B Bi Bi' B', and in such a time, by a leakage flux from the magnetic gap G provided between the Bi and Bi', a perpendicular recording medium D is magnetized, and a magnetic recording is executed. Thus, since a recording position on the medium can be scanned without moving a head, head abrasion and tape floatation due to a high-speed rotation do not occur. The high density recording, in which the relative speed of a head tape is made lower, can be attained.

Filed: 1988-08-01
Abstract: PURPOSE:To prevent the movement of a helical antenna when a core wire protrudes into a parabola by clamping the helical antenna to the parabola and connecting the core wire of a coaxial cable to the helical part of the helical antenna by a flexible conductor. CONSTITUTION:A helical antenna 3 is composed of a linear conductor and consists of a straight line part 5 made linear at a base end part and the helical part 6 provided on the extension line of said part 5 and wound in a helical shape many times in the same diameter. The connector 8 mounted to the leading end of a coaxial cable 7 is mounted to the outer part of the cup-shaped protruding circular central part of a parabola 2 by rivets 9. When a microwave flows to an antenna 1, heat loss is generated by the impedance of the coaxial cable 7 and the temp. of the coaxial cable 7 rises and, as a result, a core wire 10 is thermally expanded to protrude toward the parabola 2. Further, the coaxial cable 7 is deformed with the movement of the parabola and the core wire 10 protrudes toward the parabola 3 but the moving part at the leading end of the core wire 10 by this protrusion is absorbed by the deformation of a flexible conductor 4. Therefore, the helical antenna 3 is not moved within the parabola 2.

Title: Binarization circuit in threshold circuit
Inventor: HAGIWARA KATSUO
IPC: H03K5/08
Filed: 1984-09-18
Abstract: PURPOSE:To attain accurate reading at a high speed by selecting an optimum threshold level suitable for binarization in response to a level of a read analog signal. CONSTITUTION:Peak level change points P1-P7 are detected by a bar code S of a read analog signal A1 whose level is changed by a peak level change detection circuit (a). Thus, a variable threshold circuit (b) is controlled to hold a prescribed threshold level B1 suitable for binarization in response to the change point P1 until the detecting point of the next change point P2. When the change point P2 is detected, a threshold level B2 is held similarly until the next change point P3. This operation is repeated at each change detection point. Binarization is applied by comparing the level of the analog signal A1 with the levels B1-B7 at a comparator circuit (c). Thus, the accurate reading is attained at high speed.
