Abstract: Apparatus for monitoring the temperature of a high voltage conductor includes an electrically and thermally conductive fixture for attachment to a high voltage conductor, and a high voltage insulator having a high voltage end and a reference potential end. The insulator is connected at the high voltage end to the fixture. The insulator contains a fiber optic cable in a fiber optic cable passageway from the reference potential end to the high voltage end. The cable extends beyond the insulator. An optical temperature sensor head is optically coupled to the cable the high voltage end. The sensor head includes a sensor crystal which transmits light that varies with temperature of the sensor crystal. An electrically and thermally conductive enclosure enclosing the sensor head is supported in the fixture for thermally conductive contact with the high voltage conductor effective to couple the temperature of the high voltage conductor to the sensor crystal. An optoelectrical unit powers and detects the optic signal carrying the information about the temperature of the high voltage conductor.

Abstract: A temperature sensor for measuring a temperature of a substrate in a thermal processing chamber is described. The chamber includes a reflector forming a reflecting cavity with a substrate when the substrate is positioned in the chamber. The temperature sensor includes a probe having an input end positioned to receive radiation from the reflecting cavity, and a detector optically coupled to an output end of the probe. The radiation entering the probe includes reflected radiation and non-reflected radiation. The detector measures an intensity of a first portion of the radiation entering the probe to generate a first intensity signal and measures an intensity of a second portion of the radiation entering the probe to generate a second intensity signal. The detector is configured so that a ratio of the reflected radiation to the non-reflected radiation is higher in the first portion than the second portion. The two intensity signals are used to calculate the temperature and emissivity of the substrate.

Abstract: A semiconductor device that is capable of correctly transferring signals at high speed. The semiconductor device includes a semiconductor chip, a light-receiving element formed in the semiconductor chip for receiving an optical signal, and a glass fiber as an optical signal transfer device connected to the light-receiving element for transferring the optical signal into the semiconductor chip. Optical signals have a smaller attenuation of signal amplitude and have a higher transfer speed compared to electrical signals. Therefore, by transferring signals in the form of optical signals, the semiconductor device that can correctly transfer signals at high speed is obtained.

Abstract: An uncooled thermal matrix detector having a given spectral sensitivity range and being formed from pixels which are thermally insulated from each other, each pixel including an absorbing element which is thermosensitive in the spectral sensitivity range. The thermal matrix detector also includes on its face, turned toward the incident radiation to be detected, of each thermosensitive absorbing element, a biperiodic grating of elementary blocks limiting the viewing angle of the detector, the pitch of the grating being less than the mean wavelength of the spectral sensitivity range. The thermal matrix detector can be applied to so-called BLIP uncooled thermal detectors.

Abstract: A portable, infrared, multiple gas analyzer for measuring the concentration of a plurality of infrared absorbent gases with a simple optical arrangement for transmitting an infrared beam along an optical path along with gas mixtures to be analyzed. Light transmitting tubes arranged in a U-like configuration transmit infrared energy and the gases applied thereto over a small path to an infrared detector from an infrared source and provide electrical analog output signals representative of the detected gases. The detector output signals are processed by D.C. processing circuits including an analog to digital converter and microprocessing circuits for providing digital, binary coded, output signals representative of the detected gas concentration of the infrared absorbent gases. The analyzer can be readily calibrated by applying a non-infrared absorbent gas to the gas analyzer to provide a maximum output signal level with the infrared beam on and the background level or dark level signal with the beam off. The gas mixture having the infrared absorbent gases to be measured are applied to the analyzer for measurement and the resulting analog signals are amplified under control of a microprocessor for determining whether or not a preselected signal level stored in the microprocessor memory is exceeded or not. If not, the gain of the amplifier is increased to compensate for the aging of the analyzer. An offset voltage is applied to the analog to digital converter under control of the microprocessor to the amplified gas signals for increasing the resolution of the converter output signals only during the time intervals the absorbent gases are being measured. The microprocessor is programmed to execute a program for calculating the detected concentration of the gases undergoing analysis based on the previously acquired and stored “zero” gas level, dark level and known gas factors to provide the desired digital, binary coded, gas concentration signal from the analyzer.
