Title: Rotary fluidic machine
Inventor: MARUYAMA TERUO
IPC: F04C18/344
Filed: 1980-06-25
Abstract: PURPOSE:To obtain a vane side seal of contactless low torque not depending upon thermal expansion of a member, by placing a movable element between a vane and side plate. CONSTITUTION:A movable element 22 is inserted between a vane 20 and side plate 26. If the vane 20 travels in the direction of an arrow mark A, pressure in a vane chamber at the side of high pressure is acted upon back side part 27 of the movable element 22, to apply force fc to the movable element 22. While a power step bearing is formed between the movable element 22 and the side plate 26, and positive pressure is generated by shearing force due to a wedge oil film to apply force fB to the movable element. In this way, clearance delta1 between the movable element 22 and the side plate 26 can be always maintained to a constant value despite thermal expansion of the vane 20 and the like, thus a vane side seal not depending upon thermal expansion of members can be obtained.

Abstract: PURPOSE:To elevate the detection accuracy of oxygen concentration by calculating the temperature of an element for detecting oxygen concentration from the temperature and the value of heat generated from a heater to correct the inflow current of the detection element by the resulting calculated temperature value. CONSTITUTION:An oxygen sensor 1 is equipped with an element section 8 for detecting oxygen concentration and a heater 7. The element section 8 detects the concentration of oxygen with the action of an oxygen pump by the inflow current (diffusion current). The heater 7 is fed with a heater current Ih through a resistance R0 from a power source circuit 22 while the heater current Ih is detected with a heater current detection circuit 23 and the heater resistance Rh and the heat value Q are computed based on the heater applied voltage Vh with arithmetic circuits 24 and 25. The temperature Ts of the element section 8 is calculated with a temperature computing means 27 from these computed values. Since the coefficiency of diffusion of a porous protective layer composing the oxygen sensor 1 depends on temperature, the voltage signal Vi of the element section 8 is multiplied by the correction factor beta according to the temperature Ts to obtain an output signal Vn.

Title: Tangential servo control signal generator for recorded information reproducer
Inventor: SUZUKI KOUICHI
IPC: G11B7/09
Filed: 1979-07-12
Abstract: PURPOSE:To ensure the good compensation by giving the phase inversion to the reproduced color burst signal with every cycle, detecting the generation timing at the fixed area on the waveform of the obtained output signal to obtain the phase difference to the reference signal, and thus giving the control to the servo system. CONSTITUTION:The color burst signal is isolated from reproduced signal A thrugh color burst isolating circuit 1, and the phase inversion is given with every horizontal cycle through switch circuit 4. Accordingly, the same phase difference is obtained between the reproduced horizontal synchronous signal and the reproduced color burst signal. If the output E of the monostable multivibrator is used for the sampling signal of trapezoid wave H, the trapezoid wave level at that moment shows the phase difference between reference signal F and the reproduced color burst signal. And now in case the reproduced color burst signal has a shift of 180 deg., the timing is signal generated with the same amount of shift by the burst signal of the shifted area. Thus the phase difference signal is delivered, and the control with shift is given to the tangential mirror in the direction of the track's tangent. As a result, the compensation is given to the phase of the color burst, securing the continuous phase.

Title: Response improving device for electric signal output circuit
Inventor: NAGASHIMA TOSHIO
IPC: G05B11/36
Filed: 1993-04-16
Abstract: PURPOSE:To improve the delay of an output signal even when the electric signal output circuit includes a smoothing filter by performing compensation for leading transmission characteristics to a digital signal supplied to a conversion part having the smoothing filter for delay transmission characteristics. CONSTITUTION:The digital output value calculated by a calculated value calculation part 2 is sent to a leading element arithmetic part 3 to calculate the leading transmission characteristics. The electric signal conversion part 5 converts the output value generated by the leading operation into an electric signal. The smoothing filter 6 filters the output of the electric signal conversion part 5 and outputs the result to a control valve 7. At this time, the operation of the leading transmission characteristics performed in the calculation part 1 in advance is canceled by the delay transmission characteristics of the smoothing filter 6. Consequently, the delay of the filter 6 is reduced and the output response can be improved so that the output value can be outputted without delay even when the filter 6 is inserted.
