IPC: G01N27/00
Filed: 1982-09-13
Abstract: PURPOSE:To quickly restore the sensor function lost due to attachment of fine particle by overdriving a piezo-electric vibrator scattering fine particles attached thereto to return it quickly to the original condition. CONSTITUTION:A piezo-electric vibrator 1 as sensor body is excited with a drive level variable type oscillator 2 at a specified drive level. Said oscillator 2 is calculated, for example, with an equivalent resistance calculating circuit 3 for a vibrator 2 and the results are compared with a reference value by means of a comparator 4. When it exceeds a fixed threshold, the drive level of the oscillation circuit 2 is elevated to scatter water drop, fine dust and the like attached to the main surface of said vibrator 1 so that it returns to the original condition quickly.

Title: Gas flow rate control apparatus
Inventor: KOJIMA TADASHI
IPC: F16K31/12
Filed: 1980-11-14
Abstract: PURPOSE:To prevent the occurrence of blow-off or other undesirable occurrence by a method wherein the displacement of a feedback responsive member is controlled by an electromagnetic actuator by detecting the pressure of a gas at the outlet of the gas flow rate control apparatus and the adjustment of the gas pressure and the control of a proportional gas flow rate are performed simultaneously. CONSTITUTION:In case where a gas combustion apparatus is required to be operated, a switching valve 15 opens a valve sheet 13 and a working gas is introduced into a main diaphragm chamber 8 through a passage 17 so that the pressure of the gas rises up to make a main diaphragm 9 open a main valve 4 against the force of a spring 7 and as a result, the combustion gas flows into an outlet passage 3 through a port 5 to increase the pressure of the gas at the outlet passage 3. The gas pressure is then fed back to a feedback diaphragm 19 through a passage 26. At the same time, a electric current is supplied to an electromagnetic coil 22 through a controller to thereby push a plunger 21 downward. Consequently, the force of the plunger 21 generating due to an electric current operated by the controller and the force exerted on the feedback diaphragm 19 are balanced.

Filed: 1986-07-09
Abstract: PURPOSE:To eliminate the high pressure proof of circuit parts, to improve reliability, and to lower cost, by detecting a voltage at the tertiary winding of a flyback transformer, and turning OFF a switch with a control terminal inserted in a main power source circuit line, when the above voltage rises. CONSTITUTION:When a high voltage to be impressed on a cathoderay tube 11 rises due to an unkown cause, the voltage generated at the tertiary winding 12 of the flyback transformer 10 also rises, and a detection voltage rectified by a diode 13, and a capacitor 12, also rises.
