Title: Servo control system
Inventor: FUJITA JUN
IPC: G05B19/404
Filed: 1988-12-09
Abstract: PURPOSE:To match the gain of a low gain axis to the gain of a high gain axis without lowering the gain of the axis, whose gain can be set high, by correcting the input command of the axis, whose gain value can be set only lower than that of the other axis. CONSTITUTION:When transmission functions to include the control systems of the respective axes are defined as W1, W2...WN respectively, one of the plural axes is defined as a reference axis and the transmission function of the reference axis is defined as WR, for a pre-compensating part 10, respective transmission functions are WR/W1, WR/W2,...WR/WN and such a pre-compensating part 10 is set in front of the control system of each axis for each axis. Then, the control command of each axis is inputted to this pre-compensating part 10 and the gains of the plural axes are made coincident. In such a way, the transmission characteristic of the pre-compensating part 10 is determined. Thus, even when the position loop gain of a Y axis before correction is lower than the position loop gain of an X axis like being shown in a real line, the position loop gain of the Y axis can be made coincident to the high gain like being shown in a broken line.

Title: Air conditioner
Inventor: OOTORI MASAHIKO
IPC: F25B13/00
Filed: 1987-12-11
Abstract: PURPOSE: To enhance comfortableness by operating a heater disposed in the refrigerant suction duct of a compressor at the heating operation starting time or at the time of defrost operation in a heat pump refrigeration cycle thereby shortening the rising time of heating function. CONSTITUTION: When the temperature of an outdoor heat exchanger 3 drops below a set level at the time of stopping operation, a heater 20 functions to heat a suction cup 12. Since refrigerant suction pressure of a compressor 1 can be kept at a high level, delivery pressure rise of refrigerant is quickened to shorten the time required for reaching a hot air blowing level. Since the rising time of heating function is shortened, the time to be elapsed before hot air begins to blow is shortened. When frosting of the heat exchanger 3 progresses and the heat exchanging temperature drops below a specified level at the time of heating operation, the heater 20 is operated preliminarily for a specified time.  When a two-way valve 7 is opened subsequently while sustaining operation of the heater 20 and operation of an outdoor fan 8 is stopped, high temperature high pressure refrigerant delivered from the compressor 1 is bypassed to the heat exchanger 3 thus defrosting it.

Title: Magneto-optic information reading apparatus
Inventor: ARAN BII MAACHIYANTO
IPC: G11B7/135
Filed: 1991-11-27
Abstract: PURPOSE: To provide a device which reads information that is magneto-optically recorded in a magnetic layer and is provided with a single polarized light holding optical guide (one optical fiber or two-dimensional waveguide, for example) transmitting read light flux which is plane-polarized to a recording layer and immediately transmitting it to a photodetector when it is reflected by the recording layer. CONSTITUTION: Either TE or TM axis in the optical guide is arranged on the polarization plane of a read source. A polarization rotor such as a Faraday rotor is placed between the output terminal of the optical guide 58 and the recording medium 14. Since the Faraday rotor rotates the polarization plane of light flux by 45 degrees, the optical guide uniformly transmits reflected light at TE and TM modes. A pair of optical diodes 50 differentially detect a Kerr rotational angle (±Θk ) generated by the upper/lower orientation of a magnetic domain to which a vertical direction is given in the recording layer 14 in cooperation with polarization beam splitters 52 and 54.
