Title: Automatic control device for color selector
Inventor: SATAKE TOSHIHIKO
IPC: G01N21/85
Filed: 1979-08-09
Abstract: PURPOSE:To maintain in the optimum way both a high selection factor and selection capacity of  the grain with a high precision, by providing an automatic gain control circuit to the control circuit and then keep the steady and constant voltage at all times to the increment and decrement of  the detection sensitivity of the photodetector. CONSTITUTION:The reference value for the selected different-color grains is set to setter 21 of  control circuit 12. Then the raw grain is supplied to drive the automatic control device, and thus  the reflected rays of the different-color grains are received by photodetectors 7A and 7B. And this  detection signal is sent to circuit 12. Electromagnetic ON-OFF valve 13 of the jet nozzle device is  actuated by the output signal of circuit 12 to select the different-color grains. In this case, automatic gain control device 23 gives compensaion to the output signal of differential amplifier 19 down to a certain value of the darkest color grain if the detection signals of 7A and 7B vary by  the evaporation of water of the dust. Thus the steady value is secured for the output signal. As a  result, the output signal sent from circuit 12 can always be kept steadily at a certain level of voltage and then made clear. With this signal, valve 13 can be switched smoothly and assuredly to  ensure an accurate jet selecting action. Accordingly, both a high-accuracy selection factor and  selection capacity can be maintained in the optimum way.

Title: Hydraulic braking pressure controller in anti-skid braking system
Inventor: SATOU MASAMITSU
IPC: B60T8/40
Filed: 1980-07-25
Abstract: PURPOSE: To always perform stable operation irrespective of the thermal expansion or contraction of operating medium oil due to temperature change.  
     CONSTITUTION: A first and a second hydraulic braking pressure chambers 15, 16 are defined by a braking pistion 10 fixed with a control piston 13 which defines a hydraulic ontrol purssere chamber 20, and there are provided seal cups 27, 24 which only allow flow from an oil supply chamber 22 communicating with an oil resorvoir T to the chamber 16, and flow from the chamber 16 to the chamber 15. Due to the provision of the seal cups hydraulic pressure in the chamber 15 alone increases by hydraulic pressure induced in a master cylinder 18 through actuation of a brake  pedal 17, causing the piston 10 to increase hydraulic pressure in a wheel cylinder 19, thereby to actuate wheel brakes. If a skid is likely to arise, A hydraulic pressure control circuit 21 is operated for allowing pressurized oil in an accumulator A to flow into the chamber 20 so as to retract the piston 10, which causes hydraulic pressure in the cylinder 19 to decrease, thereby to evade the skid.

Title: Magnetic beraing control system
Inventor: MORII SHIGEKI
IPC: F16C32/04
Filed: 1986-05-02
Abstract: PURPOSE:To widen the frequency domain, in which the damping force of a magnetic bearing is generated, and reduce the instability-oriented force which occurs in the high frequency domain, by combining every feed-back signals from both a position-sensor and a speed sensor and then feeding them back. CONSTITUTION:An adding machine 13 adds up the output signal from a control circuit 3 and the output(signal) from a speed feed-back gain 12 and inputs the result into an electromagnet 4. A comparison between the force F/displacement D(of a magnet bearing) obtained through the speed feed-back and the force F/displacement D obtained through the position feed-back system composed of derivative elements only yields that there is a time-lag of degree 1 between the two. Accordingly, in the force F/displacement D obtained through the speed feed-back, the imaginary part K1 (f) becomes positive in all the frequency domain, contributing to the stabilization(damping) of the bearing. In addition, by choosing the speed feed-back gain large enough, the generation of the damping force of the magnetic bearing can be maintained up to the remarkably high frequency domain.
