Title: Gas pipe leakage detection device
Inventor: SHIRASAWA TADANORI
IPC: G01M3/00
Filed: 1991-04-25
Abstract: PURPOSE:To enable a misalarm due to a pilot flame to be reduced and reliability for detecting a leakage to be improved by memorizing a gas flow according to a combination of a plurality of gas pilot flame for a certain period for distinguishing these pilot flames from an inner-pipe leakage. CONSTITUTION:A use state detection portion 2 receives a gas flow signal G which is detected by a flow-measuring means 1, and a timer signal I or a reset signal R1 are output, respectively, depending on whether a pause interval of the gas flow signal G is shorter or longer than a specified long pause period. Also, when the pause interval is longer than a specified short pause period, a count signal C is output. A first timer portion 3 which receives a timer signal T continues counting for a specified period and an alarm signal A is output if a reset signal R1 or R2 is input during this period. On the other hand, a use state operation portion 4 continues the count signal C for a specified number of times, calculates a flow operation data Q in the case of a stable reception, and outputs this data Q to a plurality use state memory portion 7 while a second timer portion 5 is in operation.

Title: Semiconductor pressure sensor
Inventor: KATO KAZUYUKI
IPC: H01L29/84
Filed: 1992-04-16
Abstract: PURPOSE:To obtain a surface pressurized semiconductor pressure sensor in which excess silicon gel is sucked by using a jig by forming a recess to become a sucking region of an excess protective material on a residual surface of a bottom in a package. CONSTITUTION:A sufficient amount of silicon gel 7 is potted up to a level in which a chip 1, an external lead terminal 3 and wires 4 are submerged in a package, a vacuum evacuation type suction nozzle 9 is inserted obliquely sidewise into the package 5 in contact with a recess 8, and the gel 7 is sucked out. Thus, the excess gel 7 in which the chip 1, the terminal 3 and the wires 4 are buried is fluidized toward the recess 8, and sucked to the nozzle 9. When a thickness of the layer of the gel 7 covering the surfaces of the chip 1, the wires 4 is sufficiently reduced to about several tens mum, the sucking is stopped. Accordingly, an accuracy of a surface pressurized type semiconductor pressure sensor can be significantly improved by reducing the thickness of the layer of the gel covering the surface of the chip to about several tens mum.

The thickness of the polymer film is confined in the range from 0.01 to 1 micron. Namely, the liquid crystal display element contg. the cholesteric liquid crystal particles has large light scattering while voltage is not impressed thereto. The transparent and opaque contrast in on and off of the voltage, there, increases. The formation of the PVA layer contg. the liquid crystal particles to the thinner layer is possible. The driving voltage of the liquid crystal display element is thereby lowered.

Title: Disturbance eliminating device of power supply
Inventor: KAMEI KEIJI
IPC: H04N3/16
Filed: 1983-05-30
Abstract: PURPOSE:To avoid the modulation of a high frequency TV signal by impressing a horizontal higher harmonic pulse at the secondary side of a pulse transfer to the earth side of a charging circuit through a series circuit of a capacitor and a resistance. CONSTITUTION:In addition to a conventional circuit, a series circuit of a capacitor 18 and a resistance 19 is connected between the secondary and primary output terminals of a pulse transformer 5. Thus it is possible to impress the same horizontal higher harmonic pulse as that leaked out of an antenna terminal plate 16 to the earth of a charging circuit. Therefore the horizontal higher harmonic pulse is impressed with an equal potential to both ends of a diode 15a constituting an antenna switching circuit 15. Thus a higher harmonic TV signal never undergoes modulation.
