Title: Gas sensor
Inventor: OCHIWA SHINICHI
IPC: G01N27/12
Filed: 1988-08-17
Abstract: PURPOSE:To selectively oxidize only the alcohol vapor which is a disturbing gas by coating the outside surface of a gas sensitive layer with an n type oxide semiconductor added with a noble metal and increasing the concn. of the noble metal in this coating layer to the concn. higher than the concn. of the catalyst in the gas sensitive layer. CONSTITUTION:A tin oxide layer 2 which is the gas sensitive layer and is added with about 0.1-1.0% platinum, palladium, etc., is provided on electrodes 11, 12 provided to an alumina substrate 3 and the coating layer 4 consisting of tin oxide powder added with the platinum, palladium, etc., at the ratio higher by about 2-10% than the concn. in the tin oxide layer 2 is formed by firing on the outside surface thereof. The alcohol vapor is oxidized away by this coating layer and the detecting gas is hardly oxidized. The sensitivity to the alcohol vapor is thus suppressed. The alcohol oxidation activity of the coating layer 4 decreases if the concn. of the platinum, etc., in the coating layer 4 is about <=2% and the alcohol sensitivity exceeds isobutane sensitivity at about <=500 deg.C. The isobutane oxidation activity of the coating layer 4 is significant at a high temp. if the concn. is about >=10% and therefore, the usable temp. region narrows.

Abstract: PURPOSE:To detect the position of the pig in a pipe to be inspected with high accuracy, by generating ultrasonic waves from a reference position and measuring the time before the ultrasonic waves are received by the receiver mounted in the pig within the pipe to be inspected to perform operation based on the measured time. CONSTITUTION:A detection pig 1 has a means for inspecting the inner peripheral surface of a pipe P to be inspected using ultrasonic waves mounted therein and runs by itself to inspect the pipe P to be inspected and the inspection data is read in an inspection device main body 2 through a cable 3 to detect a flaw. At this time, an oscillator 31a is provided to the pipe end part of the pipe P to be inspected to generate ultrasonic waves which are, in turn, detected by the receiver 32 mounted in the detection pig 1 and the detection signal is sent to the operational control part 33 of the inspection device main body 2. The operational control part 33 measures the time DELTAT before the ultrasonic wave generating signal generated by the oscillator 31a is detected by the receiver 32. The time DELTAT is divided by an ultrasonic propagation speed (v) to operate the distance la from the oscillator 31a at a reference position to the detection pig 1. Since the position of the detection pig is calculated accurately, the position of an internal flaw can be detected with high accuracy.

Abstract: PURPOSE:To enable easy plasma ignition even when there is no metal material under a torch by inserting a metal rod in a plasma generation region only at the time of plasma ignition, and generating high voltage spark discharge with another metal material. CONSTITUTION:In the initial state of a device, argon gas or the like is fed from the hole 23 of a gas feed nozzle 22, and high frequency is applied to an RF coil 25. In this state, when high voltage is applied from a high voltage generation device 29 to a space between a metal rod 28 and an upper flange 21, high voltage spark discharge takes place between the metal rod 28 and the flange 21, and this spark discharge triggers the occurrence of plasma inside a pipe 24 and a chamber 26. Thereafter, the metal rod 28 is moved from the inside of the chamber 26 to the inside of a rod mounting and demounting mechanism 27 via the actuation thereof. Furthermore, oxygen or nitrogen gas is supplied instead of argon gas and in addition, a film formation material is fed to the inside of the pipe 24 together with carrier gas. According to the aforesaid construction, plasma ignition can be easily done even when there is no metal material below a torch.

Filed: 1987-08-19
Abstract: PURPOSE:To enable a high-output synthesized light to be obtained by omitting a cylindrical lens and reducing reflection loss so that parallel elliptical beams may be synthesized where major axes cross orthogonally each other. CONSTITUTION:Radiation light of a semiconductor laser 12 is transformed into a parallel beam by a lens 16, is allowed to radiate through a polarization synthesizer 22, while the radiation light of a semiconductor laser 18 is transformed into a parallel beam by a lens 20, is reflected by a polarization synthesized film 28 of the polarization synthesizer 22, is synthesized with emitted light from the semiconductor laser 22, and then is radiated. The far-field pattern A of synthesized light at this time becomes a synthesis of far-field patterns with approximately elliptic shape whose major axes cross orthogonally each other, thus resulting in an approximately circular shape which is symmetrical in reference to a point. Thus, a cylindrical lens which was provided between the semiconductor laser and lens can be omitted to eliminated reflection loss by the same lens.

IPC: G01R27/26
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To provide a sensor and a safety unit which can detect presence of a human body only in a desired region. SOLUTION: The sensor 22 comprises a pair of electrode plates 26, 28 disposed oppositely through a predetermined gap, and grounded shield plates 30, 32 disposed oppositely to the electrode plates on the side opposite to the gap. A decision can be made whether a part of human body is present or not between the electrode plates 26, 28 based on the variation in the capacitance thereof. No field is formed on the rear side of the electrode plates 26, 28 because of the presence of the shield plates 30, 32 and the detecting region is limited to the region between the electrode plates 26, 28. This arrangement eliminates erroneous detection and a safety unit 24 employing the sensor 22 can be operated surely only in a required region.
