Title: Automatic offset adjusting method of digital servo system
Inventor: FUTAMI SHIGERU
IPC: G05B13/00
Filed: 1984-04-28
Abstract: PURPOSE:To improve the accuracy of adjustment by detecting that generated oscillation is the one generated when a positional command is ''0'' and a servo is in the steady state, counting up the frequency of the vibration and adjusting offset voltage so that counted frequency is maximized. CONSTITUTION:Deviation parallel data 6.10 and the information of the least signified bit 6.2 are obtained from deviation counters 6.1. The information of the least significant bit 6.2 is converted into a voltage by an F/V converter 6.3 and then converted into a digital value 6.5 by an A/D converter and the digital value 6.5 is supplied to a microcomputer 6.6. The microcomputer 6.6 reads the deviation parallel data 6.10 and the digital value 6.5 and automatically adjusts an offset digitanl signal 6.7 so that the vibration of the least significant bit of the deviation is made the maximum frequency to output the adjusted value as an analog offset voltage through a D/A converter 6.8.

Title: Hydrostatic power transmission joint
Inventor: SUZUKI SATORU
IPC: F16D31/02
Filed: 1989-04-06
Abstract: PURPOSE:To enable stable operation on an antilock brake system by installing a closing means, closing an inlet passage where an inlet valve is installed, on the circumference of a rotor at time of sudden slowdown of more than the specified angular acceleration. CONSTITUTION:At time of slowdown of more than the specified angular acceleration depending upon the effect of a flywheel and a return spring 38, a flywheel- cum-rotary valve 35 (closing means) rotates in an arrow E direction and closes an inlet passage 19 by the side of a valve 35. With this inlet passage 19 closed, a hydraulic fluid fails to flow into a plunger chamber 4, or there is no hydraulic fluid to be discharged even at discharge action so that a joint comes to freedom not transfer any torque. Therefore rotation of the valve 35 is smoothly performed, and a state of sufficient freedom is created there. In consequence, front and rear wheels are isolated from each other just like in a 2WD vehicle, thus normal operation on an antilock brake system is performed.

Abstract: PURPOSE:To stop a train within a stopping accuracy without hunting at a target stopping point by sequentially switching from speed control means to position control means, constant deceleration control means and means for setting real speeds of wheels to zero. CONSTITUTION:When a target stopping point Xd of a wheel and an operating time to are input to a speed pattern generator l, a speed command value Vo is calculated, and a position command value Xo is obtained through an integrator 2.

IPC: G11B7/135
Filed: 1990-04-04
Abstract: PURPOSE:To satisfy the minimization of a device, the improvement of fitting accuracy for optics and the reduction of device cost by changing the fitting position of a half prism or of a deflected beam splitter. CONSTITUTION:A laser beam 2b for servo passes through a diaphragm lens 19 and arrives at a half prism 20a. In such a case, the prism 20a is arranged by being moved reversely to a photodetector 21. Thus, a center of the incident beam 2b to be made incident to the prism 20a is made higher than the center of an incident surface 20a-1 of the prism 20a, namely, this beam is made incident on the side of an emissive surface 20a-2 of the beam reflected by the prism 20a. At such a time, the moving amount of the prism 20a is suppressed within a certain range so that the light flux diameter of the laser beam 2b to be made incident to the prism 20a can not get out of the effective diameter of the prism 20a. Thus, the photodetector 1 can be arranged near the laser beam 2b.

Title: Phase locked loop circuit
Inventor: KIUCHI TOYOO
IPC: G11B20/14
Filed: 1987-04-09
Abstract: PURPOSE:To prevent wrong locking operations and perform quick locking operations, by counting clocks locked by a PLL and setting a follow-up control ling circuit to its initialized state, and then, cancelling the locking of the PLL. CONSTITUTION:The oscillating frequency of a VFO 1 and cutoff frequency of an LPF 4 are controlled by means of the follow-up controlling signal of a follow-up controlling circuit 3 which is outputted in accordance with data read out from a disk, etc., and the clock of sampling signals is locked by a closed loop PLL composed of a phase comparator 2 and the LPF 4 and VFO 1. When the clock is counted by a counting circuit 5 and the counted value of the circuit 5 becomes larger than a prescribed value because the clock is locked to frequency signals of two times larger or no synchronizing signal is produced at the time of counting a prescribed number under an unstable condition where the state of the PLL does not make transition until the number of clocks reach a fixed value, the follow-up controlling circuit 3 is set to its initialized state by means of reset signals from the circuit 5 and the VFO 1 can restore to its self-running state. Therefore, wrong locking operations can be prevented and quick locking operations can be performed.

Abstract: PROBLEM TO BE SOLVED: To provide the method and device for magnetic pattern recognition which can prevent the influence of magnetic noise from a pulse motor when magnetic ink character recognition(MICR) characters are recognized while check paper where the MICR characters are given is conveyed by using the pulse motor. SOLUTION: While the pulse motor is placed in operation, a signal detected by a magnetic head in an area where no MICR character is given is acquired in a step 71 in synchronism with driving pulses and this is repeated by several cycles; and the center value is used as data for correction in a step 74. In a step 75, a signal detected by the magnetic head in the area where the MICR characters are given is acquired in synchronism with the driving pulses, and the data for correction are subtracted from the signal to obtain recognition data on the MICR characters. This correcting process is performed to improve the recognition rate of the MICR characters.
