Abstract: PURPOSE:To measure the concentration of gas with high accuracy by performing drift compensation caused by the difference between the temp. coefficients of the detection outputs of gas absorption wavelength and non-absorption wavelength by providing an infrared ray detection circuit and using a specific power calculus means. CONSTITUTION:This apparatus has an infrared ray detection circuit 10 converting infrared rays to an electric signal using an RbSe infrared sensor, a power calculus means issues the output of a DC level detection circuit on the basis of an exponent 2(m-1) and a multiplying means 18 multiplying the output of said power calculus means and that of a division means. In this case, the ratio of the temp. coefficient alpha1 of the resistance change portion to the incident quantity of the infrared rays having a wavelength absorbed by specific gas of the PbSe infrared sensor varying exponentially with respect to a temp. change and the temp. coefficient alpha2 of the resistance change portion to the incident quantity of infrared rays having a wavelength not absorbed by the specific gas of the RbSe infrared sensor varying exponentially with respect to the temp. change in the same way is set. By this method, the concn. of gas is accurately detected and the drift caused by temp. characteristics is also compensated.

Title: Spread spectrum receiver
Inventor: KURIHARA TAKAO
IPC: H04J13/00
Filed: 1989-02-28
Abstract: PURPOSE:To enable an operation for initial synchronization even unless the quality of a radio wave propagation path which deteriorates recovers by controlling the phase of a reference PN code and correcting setting the coincidence position between the received PN code of a correlator and the reference PN code. CONSTITUTION:Desired information is demodulated by the correlator 1 which correlates a received artificial noise (received PN) code with the reference PN code. Here, the output of the correlator 1 is inputted to pattern decision means 2 and 3 and unless a coincidence with a specific decision pattern is obtained within a constant time, decision patterns which are similar to the specific decision patterns are switched one after another every time constant time lapses to control the phase of the reference PN code with the output when the coincidence with some pattern is obtained, thereby accurately setting the coincidence position between both codes at the correlator 1. Consequently, the operation for the initial synchronization is enabled unless the quality of the radio wave propagation path which deteriorates is recovered.

Title: Contact structure for vacuum breaker
Inventor: YOHAN BUORUFU
IPC: H01H33/664
Filed: 1982-03-24
Abstract: A configuration for a contact arrangement is disclosed for a switch having two coaxially positioned and generally cylindrical contacts. Each contact contains a coaxial core of ferromagnetic material, and a current-carrying envelope surrounding the core has the form of a helix. The helical envelope creates a current component which sets up a magnetic field in the widening contact gap when the contacts are separated that disperses arcing. Moreover, the field reinforces the closure pressure when the contacts are in their closed position. Ellipsoid shaping enables the field to be normal at all points of the contact-making surfaces.

Title: High voltage thyristor switchgear
Inventor: HASHIMOTO ISAO
IPC: H03K17/73
Filed: 1983-03-23
Abstract: PURPOSE:To prevent the erroneous operation due to noise or the like and to reduce the gate loss of a thyristor by automatically applying a reverse bias when the thyristor is OFF, and further leaking charge to become the overvoltage source when turning ON and OFF. CONSTITUTION:When a switchgear is OFF, i.e., when thyristors 11 are OFF, a voltage divided by a resistor Rb(K-1) and BB(K-1) is applied between the gate and the cathode of a GTOK, thereby improving the noise resistance to prevent the erroneous operation. The resistor RB(K-1) operates also as a function of the leakage resistor of the overvoltage applied to the GTOK. When a switch ON command is inputted to the gate of the thyristor GTO1, thyristors GTO2-GTOK are sequentially turned ON. When a switch OFF command is inputted to the gate of the GTO1, the thyristors GTO2-GTOK are sequentially turned OFF.

Title: Production of oxygen sensor
Inventor: SHIRAISHI HIDEO
IPC: G01N27/41
Filed: 1986-03-05
Abstract: PURPOSE:To shorten a process for producing a sensor by forming a mixture composed of hardly sinterable pulverized ceramic particles and pulverized noble metallic particles and calcining the mixture to form an electrode. CONSTITUTION:A green sheet 2 for oxygen ion conductive ceramics is formed of ultrafine particles of zirconia stabilized by yttria (Y2O3) in the production of the threshold current type oxygen sensor. A mixture 24 of the paste for the electrode is coated on such green sheet 2. The pulverized zirconia particles 24A which are the pulverized ceramic particles having relatively hard sinterability as compared to the oxygen ion conductive ceramics and the ultrafine platinum particles 24C which are the pulverized noble metallic particles are mixed together with a binder 24B to prepare the above-mentioned mixture 24. The ultrafine platinum particles24 are thus calcined to the porous electrode even if the green sheet 2 of the oxygen ion conductive ceramics and the paste mixture 24 for the electrode are calcined at about 1,500 deg.C. Since the production is executed by the single calcination stage, the stage for producing the sensor is shortened.
