Title: Controlling system and device for synchronous motor
Inventor: ISHIDA HIROSHI
IPC: H02P25/026
Filed: 1981-03-16
Abstract: PURPOSE: To drive and control equivalently a synchronous motor to a DC motor by detecting the phase of the induced electromotive force of a rotary field synchronous motor to generate a current command having the same phase as the detected phase and flowing an armature current of the same phase as the induced electromotive force in an armature coil.  
     CONSTITUTION: The field pole position of a synchronous motor 101 is detected by a resolver 102, and sinθ and cosθ are outputted from a synchronization rectifier 103. Further, the difference between the actual speed from a tachometer generator 104 and the speed command is applied to an error amplifier 106, the output of the amplifier is multiplied by the sinθ and cosθ, thereby obtaining a current command, the command is then passed through a 2-phase to 3-phase converter 109, and is added to the actual current, thereby controlling the power transistors Q 1 ∼Q 6  of an inverter 105. Accordingly, the induced electromotive force is detected from the position of the field pole and the armature current having the same phase as the detected phase is supplied to an armature coil. Thus, the torque equivalent to a DC motor can be produced from the induction motor.

Title: Method for measuring shape of object using optical beam
Inventor: ITO GIICHI
IPC: G01B11/24
Filed: 1988-02-22
Abstract: PURPOSE:To identify a false measured value from a real measured value so that even a V-groove constituted of lustrous surfaces can be measured by scanning the surface of the V-groove by using an optical beam and causing a light receiver to detect the effective primary reflecting light from one slope and the effective secondary reflecting light having an optical path which is regularly reflected by the slope. CONSTITUTION:In case where a light receiver R can detect the effective primary reflecting light rA from the sample surface, for example, a bright point A of a V-groove UVW when the V-groove UVW is scanned by using an optical beam (l), shapes of both slopes of the groove UVW are calculated by triangulation method from the light receiving direction, optical beam l, and measuring base line length between measuring base lines OR and OL. When the light receiver R can detect the effect primary reflecting light rA from one slope UV and the effective secondary reflecting light rB having an optical path which is regularly reflected by the slope UV and cannot detect sufficient effective primary reflecting light from the other slope VW, the shape of the slope UV is calculated by using the effective primary reflecting light rA and optical beam (l) and the slope VW is calculated by using the calculated shape of the slope UV and effective secondary reflecting light rB.

Title: Rotor with radial magnetic bearing
Inventor: KANEMITSU YOICHI
IPC: H02K7/09
Filed: 1989-02-17
Abstract: PURPOSE:To weed out the oscillation of rotor bending natural frequency by inserting a column made of a material with periodic damping activity larger than the material of a rotating shaft the same in outside diameter as in a circular hole of the rotating shaft, and by getting that column to perform flexural oscillation when the rotating shaft oscillates. CONSTITUTION:A circular hole 2 concentric to the center line of a rotating shaft 1 is formed to the rotating shaft 1. A column 3 made of a material with periodic damping activity such as lead, Mg-Zr alloy, etc., larger than the material of the rotating shaft 1 and having the same outside diameter as that of the circular hole 2 is inserted into this circular hole 2 and is fixed there. When the rotating shaft 1 is bendingly deformed, the column 3 receives the bending deformation likewise. Since it induces the damping action on the material constituting this column 3, the damping activity of the rotating shaft can thereby be improved.

Title: Automatic gain adjusting circuit
Inventor: HIKITA JIYUNICHI
IPC: H04B1/16
Filed: 1984-02-29
Abstract: PURPOSE:To ensure gain adjustment at strong input by providing a switching circuit conductive at the strong input to an input section of a frequency mixer circuit so as to decrease the level of signal input. CONSTITUTION:A reception signal is applied to the mixer circuit 4 from an antenna 2 via a tuning circuit. Further, an oscillation output is fed from a mixer oscillator 48 and a mixer output is outputted to an intermediate frequency amplifier via an intermediate frequency tuning circuit 52. When an AGC input 12 is a strong input in excess of a threshold value, a base current of a transistor (TR) 34 flows via a voltage/current converting circuit 72 in response to the strong input, a TR34 is conductive, the impedance between bases of TRs 14, 16 is decreased and a common mode input is given to a differential input of the TRs 14, 16. Thus, the AGC effect for suppressing the effect of the common mode amplification gain of the differential amplifier is obtained at the strong input and the gain is adjusted without decreasing remarkably the input impedance of the mixer circuit.
