Title: Method and device for testing water leakage in piping system
Inventor: UEDA YUTAKA
IPC: G01M99/00
Filed: 1983-03-04
Abstract: PURPOSE:To enable early discovery of a defective point before completion by fluctuating the pressure in a test piping by the combination of pressurizing means and a stop valve so that the fatigue in the potential defective part is accelerated. CONSTITUTION:A storage tank 1, a pressurizing pump 2 and a test piping 3 are connected respectively to each other by means of pipings 4, 5. When the pressure in the piping 3 is increased by driving the pump 2 and opening or closing a stop valve 8 by operating a open/shut driving mechanism 9, the pressure in the piping 3 is decreased sharply by the opening of the valve 8. The pressure increases again when the valve is closed. The discharging rate of water is adjusted by a valve 10, and the period for opening and closing the valve is adjusted by the mechanism 9, by which the pressure is set at the fluctuating width which is most suitable for the test sample. If the pressure in the test piping is fluctuated in such a way, a dynamic pressure is continuously exerted on the joint part which is a potential defective part, by which the fatigue is accelerated and leakage of water is generated.

Title: Color picture quality automatic regulating circuit
Inventor: SAGAWA TAKAHIRO
IPC: H04N9/73
Filed: 1988-02-19
Abstract: PURPOSE:To always obtain a clear color picture by multiplexing a pedestal- clamped primary color video signal, converting it into a digital value, detecting the peak value of the output of a multiplexer and applying it as the conversion upper limit reference voltage of an A/D converter. CONSTITUTION:A video signal 18 after multiplexing is inputted to a peak detecting circuit, a capacitor 10 is charged and held by a peak voltage. Since the voltage of the capacitor 10 is lower than the peak voltage of the video signal 18 by the forward direction voltage portion of a diode 8, it is raised and equalized by a diode 9. Further, an impedance is lowered by buffer transistors 12 and 13, and the voltage is applied to an A/D converter 5 as an upper limit reference voltage 19. Consequently, even when the modulation factor of the video signal changes, the upper limit reference voltage of the A/D converter 5 follows the peak voltage, and the pedestal level of the video signal always corresponds to the lower limit reference voltage of the A/D converter 5. Thus, the best contrast and luminance can be always obtained.

Title: Muting circuit
Inventor: KOYANAGI TATSURO
IPC: H03F3/72
Filed: 1989-02-15
Abstract: PURPOSE:To prevent production of pop noise by disconnecting a negative feedback loop of an amplifier to apply muting. CONSTITUTION:When an output signal of a power amplifier 6 is fed to a base of a 2nd transistor(TR) 25 through a negative feedback circuit 28, the audio signal is amplified depending on the negative feedback quantity and fed to a speaker 7. With a switch 29 opened, a negative feedback signal is not fed to a base of the TR 25 and the same level of the audio signal is applied in phase to bases of TRs 24, 25. In this case, a bias voltage of the TRs 24, 25 depends on a bias source 32 and since a single constant current source 26 is in use, no DC fluctuation at an output terminal 34 exists. Thus, no popping noise is generated and the hardware muting is applied.

IPC: H01R13/64
Filed: 1991-02-07
Abstract: PURPOSE:To easily detect incomplete insertion of a terminal into a connector housing. CONSTITUTION:A lance 26 is provided with such a function as to prevent a terminal 22 from being drawn out because it is snapped in the terminal 22 when the terminal 22 is inserted into a terminal containing chamber 23.
