Title: Water supply controller
Inventor: OGAWARA HIROSHI
IPC: G05B11/32
Filed: 1988-04-28
Abstract: PURPOSE:To ensure the stable control of water supply even in case the temperature of the exhaust gas supplied to an exhaust heat collecting heat exchanger is suddenly changed by cutting off the rotational frequency signal produced based on three elements and supplied to a driving device and supplying newly the rotational frequency signal obtained based on the temperature change rate. CONSTITUTION:A water supply pump 13 contains a driving device 14 and the rotational frequency of the pump 13 is controlled by the control signal produced based on three elements during a normal operation. In case the temperature of the exhaust gas flowing to an exhaust heat collecting heat exchanger 1 rises up and this temperature change rate exceeds a prescribed level, the supply of the rotational frequency signal is cut to the device 14. Then the device 14 is controlled by a new rotational frequency signal obtained through a prescribed arithmetic operation carried out based on the temperature change rate of the exhaust gas. As a result, the rotational frequency of the pump 13 increases and the water supply pressure is increased to a fuel economizer 2. Thus the supplied water never evaporates at a place near the outlet of the economizer 2.

Filed: 1978-08-30
Abstract: PURPOSE:To enable to detect the abnormal pressure without placing the power supply in the tire of a car, by providing crystal oscillator in the enclosed space and using the attenuating oscillation after the excitation of oscillator. CONSTITUTION:At the enclosed space 6 such as tire of a car, the coil 3 and the pressure response switch 2 are provided in parallel with the crystal oscillator 1. Further, after transmitting electromagnetic waves epual in the frequency of the natural vibration frequency of the oscillator 1 from the external transceiver 4, the transceiver 4 is selected to a receiver. In this case, if the pressure in the space 6 is normal, the switch 2 keeps OFF, and the attenuating oscillation after the excitation of the oscillator 1 is detected with the receiver 4 via the coil 3. On the other hand, if the pressure in the space 6 is abnormal, the attenuating oscillation of the oscillator 1 is shortened with the switch 2 turned on and it is not detected by the receiver 4.

Filed: 1979-08-20
Abstract: PURPOSE:To lower the stray light level and to increase the spectrosensitivity, by making different the heights of inlet and outlet slits and providing the light absorbing means around the both sides of the outlet slit. CONSTITUTION:The inlet slit S1 and the outlet slit S2 are located by separating them at upper and lower side of the plane F through tilted line tying the center.

A present position existence range arithmetic means 105 derives a range having possibility that the present position exists, for instance, as a rectangle, based on the running distance and the advance azimuth. A map matching arithmetic means 107 searches the road data contained in the rectangle and estimates a running road from a difference between the advance azimuth and the road azimuth, etc., and if it can be estimated, the conjecture position is corrected onto this road, and it is outputted.

Title: Manufacture of piezoelectric buzzer
Inventor: UENO KATSUNORI
IPC: G10K9/12
Filed: 1988-04-28
Abstract: PURPOSE:To prevent a crack from being generated by respectively executing the polarization processing of piezoelectric ceramics before and after the piezoelectric ceramics is adhered with a diaphragm. CONSTITUTION:Before piezoelectric ceramics 2 is adhered with a diaphragm 1, a high voltage is impressed to the piezoelectric ceramics and the first polarization processing is executed. With accompanying this polarization processing, a shape deformation is generated and the piezoelectric ceramics 2 is extended in a thickness direction and contracted in a radius direction on the other hand. However, since the polarization processing is executed before the piezoelectric ceramics is adhered with the diaphragm 1, distortion is not generated in the internal part of the piezoelectric ceramics 2. Next, the high voltage is impressed again to this piezoelectric ceramics 2 and the second polarization processing is executed. By the impression of the high voltage at the time of this polarization processing, the deformation change is generated in the piezoelectric ceramics 2. However, this piezoelectric ceramics 2 is once deformed at the time of the first polarization processing and deformation quantity is small at the time of the second polarization processing. Thus, the crack, which is caused by the deformation, can be prevented from being generated.

Title: Image sensor
Inventor: SAITO TAMIO
IPC: H04N1/028
Filed: 1994-04-25
Abstract: PURPOSE:To provide the high-speed reading image sensor by taking out a signal of a photoelectric conversion element which is amplified by an amplifier by a switching means and reducing the noise. CONSTITUTION:An amplifier Pn is interposed between a photoelectric conversion element An (n=1-N) and a switching means Bn. A reset switching means B'n is interposed between a photoelectric conversion element An and the amplifier Pn. Thus, the S/N is improved by performing amplification in the former step of the switching means Bn being the noise generation source. More amplifier may be provided at the final stage of a common output line. If such an amplifier Pn is provided, a means which returns the photoelectric conversion element An to the initial state temporarily is required after reading signals. This operation can return, for example, the earth potential after reading signals by the reset switching means B'n. The reset switching means B'n can be driven by using a shift register selecting the switching means Bn.

Abstract: PURPOSE: To form an excellent indented pattern by improving interfacial exfoliation of impregnated resin in such a manner that a pattern is drawn on a base material surface with an ink containing a special vehicle resin, etc., and after being solidified once, it is impregnated with surface decorating resin.  
     CONSTITUTION: By using an ink containing a vehicle resin having capability of exfoliating the impregnated thermal hardening resin and a hardening inhibitor to control the thermal hardening resin, a pattern 2 is drawn on a decorating paper 1 and then it is dried and solidified. And the surface is impregnated with a thermal hardening resin liquid containing an inorganic powder and dried so that an unhardened thermal hardening resin film 3 is formed. This resin-impregnated paper is piled on a base material 4 with the pattern-bearing side 2 on top and thermally pressed after piling a forming plate 5 on it so that only resin 6 of non-pattern section is hardened. And then, it is released from pressure under heated condition and the forming plate 5 is pulled off to remove unhardened resin section on the pattern 2, so that a projected-and-indented pattern corresponding to the pattern 2 is formed.  
     EFFECT: Thus formed pattern excels in wear-resisting and solution (or solvent)- resisting capabilities.
