Title: Synchronous motor
Inventor: KOMATSU FUMITO
IPC: H02P1/46
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To realize high reliability and compactness by positively performing shift from the start operation to synchronous operation by controlling an operation transfer switch from a star operation circuit to a synchronous operation switch, when the number of revolutions of a permanent magnet rotor reaches the number of synchronous revolutions relative to power supply frequency. SOLUTION: A microcomputer 22 controls each switching means of a start operation circuit 14 and performs start operation by suppressing the input at the inversion side relative to a non-inversion side by alternately switching the current direction of a rectifying current which flows into a coil A. Then when the number of revolutions of a permanent magnet rotor detected by an optical sensor 12 reaches the number of synchronous revolutions, first to fourth transistors 16 to 19 are turned off, so that TRIACs SW1, SW2 are turned on to transit to the synchronous operation circuit 21 for the control of shifting to the synchronous operation. By doing this, shift from the start-up operation to a synchronous operation can be performed positively with high reliability, high safety and accelerated miniaturization is also promoted.

Title: Driving method and device for stepping motor
Inventor: TAKAHASHI MASAKI
IPC: H02P8/22
Filed: 1989-10-20
Abstract: PURPOSE:To suppress fluctuation of speed of a stepping motor by varying sinusoidal currents to be applied on a plurality of exciting windings, simultaneously for respective phases and repeatedly for every period of the exciting phase, in response only to the fluctuation of speed within single period of each exciting phase. CONSTITUTION:Upon rising of output from a speed setter 70, an arithmetic unit 60 reads out speed fluctuation correcting data corresponding to the output from the speed setter 70 from a memory circuit 50, and outputs a sequence output pulse and a current waveform output signal. A distribution circuit 40 scans power transistors in an exciting circuit 30 in sequence, and outputs a base signal so that current in each phase has sinusoidal waveform containing speed corrected component. Each exciting phase A, bars A, B, exciting timing and current waveform of the bar B are then controlled in consideration of inherent speed fluctuation of a stepping motor 1. By such arrangement, speed fluctuation of the stepping motor 1 can be suppressed.

Abstract: PURPOSE:To substantially reduce the vibration of a table by installing a damping motor, to the rotary shaft of which an inertia loading body is connected, and which rotates in the direction opposite to the rotary direction of a drive motor, to a supporting body. CONSTITUTION:When a damping motor 11 is rotated in the direction opposite to the rotary direction of a driver motor 5, the inertia generated in the inertia loading body 10 mounted on the rotary shaft 10 of the damping motor 11 works so as to cancel the inertia of a table at the moment of switching the moving direction of the table. This constitution serves to restrain the magnitude of the vibration of the table, if generated, and also shorten the residual vibration period. Therefore, the selection of the proper magnitude of the inertia to be generated in the inertia loading body 10 accelerate the moving speed of the table maintaining high accuracy constant for making it possible to perform high speed machining.

Filed: 1984-12-24
Abstract: PURPOSE:To make the size of gel very small and to improve the degree of resolution of an optical element by using a polymer capable of absorbing liquid at low temp. and desorbing the liquid at high temp. as optical element. CONSTITUTION:An optical element is formed of a substrate 1, a gel-contg. layer 2, and a transparent protecting plate 3. A transparent substrate such as glass is used for the substrate 1. A polymer capable of absorbing liquid at low temp. and desorbing the liquid at high temp., such as crosslinked polymer of acrylamide deriv. is used in the gel-contg. layer 2 wherein the polymer is mixed with the liquid. When the optical element is not irradiated with infrared rays, the gel is swollen and the gel-contg. layer becomes light transmissive 6-2. When the element is irradiated with infrared rays 5, the gel 4-1 becomes small particle size with scattering effect for light, so the gel-contg. layer 2 scatters the light 6-1 exhibiting milky white color. Thus, an optical element contg. gel of small particle size and having improved degree of resolution is prepd.
