Title: Driving circuit for moving device
Inventor: GOTO MASAO
IPC: G02B7/08
Filed: 1985-03-25
Abstract: PURPOSE:To make the presence of slight variances allowable by driving moving base on which an optical system such as a pickup, etc. has been placed, by the first and the second motors, and executing servo-control by applying an output of a detecting means for detecting a rotating speed of the first (or the second) motor, to the second (or the first) motor. CONSTITUTION:A moving base 2 is constituted so that it can move to the right and left along guide rails 3a, 3b, the first motor M1 is provided on a fixed part such as a chassis, etc., and a screw S is rotated by the motor M1. On the other hand, to the moving base 2, the second driving motor M2 is attached and a worm gear G is engaged, and for instance, by pressing the screw S against the gear G by rotation of the worm gear G, the moving base 2 moves to the right and left. Also, in case when the second driving motor M2 is not rotating but only the first driving motor M1 is rotating, the moving base 2 can be moved to the right and left by pressing the gear G against the screw S side by rotation of the screw S. When the first and the second motors are driven in this way, the sum of speeds of both the motors is obtained, and the moving base 2 can be moved at a very high speed.

Title: Electric motor controller
Inventor: MORITA KUNITOSHI
IPC: G05D3/00
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To provide the controller which can return a moving body to its origin precisely even when the electric motor driving it rotates at a high speed and shorten the time needed to return it to the origin. SOLUTION: A position calculation part 3 counts pulse signals outputted by a position detecting means 2 detecting the rotation of the electric motor 1 and outputs a position count value corresponding to the movement quantity of the moving body 7, and a 1st position storage part 4 updates and holds this position count value. A 2nd position storage part 6 reads in the said position count value at the point of time of the output of a Z-phase pulse of every rotation of the electric motor 1 outputted by the position detecting means 2 and holds it as a Z marker value. A controller 5 regards the marker value as the rotation reference position of the electric motor 1 and controls its rotation according to the position count value in the 1st position storage part 4.  The 2nd position storage part 6 reads in the position count value instantaneously at the Z-phase pulse output point of time independently of the controller 5, so there is no error in value due to read-in delay and the controller 5 does not read in the said position count value by an interruption process, so there is no error in position generated, so that an accurate return to the origin can be made even in the case of high-speed rotation.

Title: Speed detector
Inventor: ISHIDA HIROSHI
IPC: H02P29/00
Filed: 1981-04-22
Abstract: PURPOSE: To attain the detection of speed with high accuracy regardless of a high or low speed, by selecting the speed signal based on the two pairs of frequency signals corresponding to the speeds of phases different by π/2 in a low- speed mode and the reverse signals of the above-mentioned frequency signals.  
     CONSTITUTION: Detection outputs PA and PB having the frequency (f) corresponding to the speed given from a pulse generator 101 with the phases different by π/2 are processed through reverse amplifiers 102 and 103, pulse converting circuits 104 and 105 plus a quadrupling circuit 106 respectively to produce an output of frequency (f). Then the voltage corresponding to the speed given from a frequency-voltage converter 107 incorporating an integral network, etc. is produced. On the other hand, the outputs PA and PB plus their reverse outputs are applied to switches S 1 WS 4  of a synchronous rectifying circuit 109 which is controlled by the coutput of the circuit 106 via a differentiating circuit 108 to produce the voltage corresponding to the speed in a low-speed mode. The outputs of these converter 107 and curcuit 109 are selected by a detecting circuit 110 according to a high or low speed. In a low-speed mode, the output of the converter 107 having a reduction of accuracy is not selected. Thus the detection of speed is possible with high accuracy regardless of a high or low speed.

Title: Magnetic recording and reproducing device
Inventor: FUJIWARA NAOHISA
IPC: H04N5/783
Filed: 1986-03-18
Abstract: PURPOSE:To allow only a normal reproduction head to obtain a reproduced picture signal with an excellent S/N by using a reproduction head with width similar to a track pitch and reading a signal with an excellent S/N written in a memory right before a special reproduction starts. CONSTITUTION:The normal reproduction heads 4a and 5a have the same width as that of a track pitch. When the head 5a executes its normal reproduction, components in crosstalk from adjacent tracks become zero as figure shows, and the noise of the crosstalk disappears. As a result a reproduced picture signal with an excellent S/N can be obtained. When the head reproduces a still picture, parts 9a and 10b where a reproduction level in the envelope waveform of the output 15 of a head amplifier is lower than the threshold level of a reproduction processing circuit 16 arise to develop noise on a screen. However a noise-free reproduced image is written in a field memory 18 in a normal reproduction state right before a tape stops, and the output of the memory 18 is read at the time of reproducing a still picture.
