Title: Pyroelectric infrared temperature sensor
Inventor: KAI JUNICHI
IPC: H01L37/02
Filed: 1993-04-22
Abstract: PURPOSE:To provide a pyroelectric infrared temperature sensor which can detect the temperature at high sensitivity. CONSTITUTION:The pyroelectric infrared temperature sensor A has such structure as infrared rays L impinges on a pyroelectric part 1 through an optical wavelength selective filter 2 wherein the filter 2 preferably comprises an interference film having light transmittance varying abruptly in the vicinity of the wavelength of an object to be detected. The pyroelectric temperature sensor has such properties as the polarization is varied significantly even by a microdifference in the wavelength of infrared rays emitted from the object. Consequently, resolution of 0.1 deg.C and measurement error of + or -0.5 deg.C are attained over a wide temperature range of -50-2000 deg.C thus realizing a high sensitivity pyroelectric infrared temperature sensor in which the resolution is increased by a factor of 10 while decreasing the measurement error by a factor of 4 as compared with a conventional pyroelectric infrared temperature sensor.

Title: Light transmitter/receiver
Inventor: SASAI HIROYUKI
IPC: H04B10/61
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To simply and inexpensively constitute a light transmitter/receiver. SOLUTION: A modulated electric signal Smod generated by modulating the amplitude of a high frequency (millimeter wave band) subcarrier by a base band signal SBB to be transmitted and a main carrier MC outputted from a light source 110 are inputted to an external light modulation part 120 in a light transmitter 101. The modulation part 120 modulates the amplitude of the main carrier MC by the signal Smod and outputs a double modulated optical signal OSdmod to an optical filter part 130. The filter part 130 transmits only one side band wave component included in the signal OSdmod and projects the transmitted signal to an optical fiber 140 as an optical signal OS. A photoelectric conversion part 150 in a light receiver 102 directly obtains a base band signal SBB by photoelectrically converting the optical signal OS transmitted through the fiber 140.

Abstract: PROBLEM TO BE SOLVED: To detect an error in a low pressure range from an error in a high pressure range, by forming a pressure signal depending on pressure in the low pressure range, and using an error signal and the pressure signal for detecting the error. SOLUTION: A control part 150 inputs the output signals of various sensors 160 and calculates the operating control signal of an injector 131. Also, the control part 150 forms a signal by which voltage is applied which opens a pressure control valve 135 by a predetermined pressure in a high pressure range. Further, when detecting that an error occurs from the output signal of a pressure sensor 140 in the high pressure range, the control part 150 forms, for example, a control signal for disconnecting an internal combustion engine. At this time, a monitoring sub-program in a low pressure area is operated, for example, after lapse of a predetermined time, especially advantageously, after detecting the error in the high pressure range, and it is judged whether or not pressure PN in the low pressure range is smaller than a threshold value PS according to the sub-program.  Then, in the case of PN<PS, a marker is set to zero, and in the case of PN>PS, the marker is set to 1.

IPC: G01N27/416
Filed: 1994-05-11
Abstract: PURPOSE:To obtain a high sensitivity incomplete combustion detecting element by forming a pair of cermet electrodes, composed of a platinum based metal and an oxide, on the surface of an oxygen ion conductive solid electrolyte and covering one of them with an oxidation catalyst. CONSTITUTION:A pair of cermet electrodes 2, 3 are formed by applying a mixture paste of Pt powder and ZrO2 powder stabilized by Y2O3 to the opposite sides of a ZrO2 substrate 1 stabilized by an oxygen ion conductive solid electrolyte, i.e., Y2O3. A paste of alumina powder, impregnated with Pt, is then applied while covering the electrode 2 to form a flammable gas oxidation catalyst layer 4. The three-phase interface, where reaction takes place between a flammable gas and the electrode 2, increases between the electrode 2 and the border of the substrate 1 thus preventing growth of Pt particles. When the flammable gas touches the detecting element, chemical reaction takes place between the flammable gas and the electrode 2 on the three-phase interface formed at the border between the electrode 2 and the substrate 1 to generate electromotive force between the electrodes 2, 3. Presence of flammable gas is detected, along with the concentration, by detecting the electromotive force.

Abstract: PURPOSE:To detect a fault where a hopping switch is interrupted or conducted by comparing an output signal of the hopping switch with a signal fed to the said switch to output the output signal. CONSTITUTION:If no output is fed to the, e.g., i-th transmission system from the hopping switch 2, a detection circuit 8i transmits no output signal and since a signal (e) is outputted from an AND circuit 9i with a burst signal (b) from a terminal station device 1 and a selection control signal, an output (f) of an EOR circuit 10i activates a holding circuit 12 and an alarm is raised. On the other hand, the switch 2 is conducted and all timing signals of an intermediate frequency signal (a) transmitted from the terminal station device to a terminal 2 are transmitted to the i-th transmission system, then a signal (g) is outputted from the detection circuit 8i. In this case, since the AND circuit 9i outputs the signal (e), a signal (h) is outputted from an EOR circuit 10i and the holding circuit 12 is operated.
