Title: 3-phase current output circuit
Inventor: ASHIZAKI YUKIHIRO
IPC: H02P6/08
Filed: 1987-03-02
Abstract: PURPOSE:To accurately regulate the temperature characteristic of a 3-phase current output circuit by constructing to have similar positive temperature coefficient in first and second current sources of the output circuit. CONSTITUTION:A feeder line is formed of first-third feeders 1-3, and a 3-phase current output circuit is composed of an N-P-N transistor 6, a plurality of diodes 7 connected forwardly in series with the emitter, a first resistor 8 and a current mirror circuit 9. The fine adjustment of the temperature coefficient is conducted by regulating the resistance ratio of resistors 4, 5 at the base potential of the transistor 6. Thus, since the variations in the voltage drops with respect to the temperature by the diode 7, the transistor 6 and the circuit 9 are the same, the temperature coefficient of the rectified value of the circuit 9 can be continuously varied.

Title: Thin film forming method
Inventor: KARASAWA TAKESHI
IPC: H01L21/316
Filed: 1988-02-29
Abstract: PURPOSE:To make it possible to form, on germanium, a silicon dioxide thin film having excellent insulating properties and interfacial characteristics, by a method wherein, after silicon is epitaxially grown on germanium, the silicon is thermally oxidized in an oxygen atmosphere for a time longer than or equal to the least possible period necessary to oxidize all silicons. CONSTITUTION:On a germanium substrate 1, silicon 2 is epitaxially grown with a desired thickness. The silicon 2 on the germanium 1 is thermally oxidized in an oxygen atmosphere to form a silicon dioxide layer 3. In this case, the thermal treatment is continued for a time longer than or equal to the period in which the silicon is all oxidized. Even if the silicon is subjected to such long thermal oxidation, time the germanium is not oxidized, because the thermal oxidation is interrupted on the boundary between the silicon and the germanium. Therefore when the heat treatment is performed in the oxygen atmosphere for a sufficient period wherein the silicon is all oxidized, the thickness of the silicon oxide film is determined by the film thickness of silicon epitaxially grown on the germanium, independent of the treatment time.

Filed: 1990-02-28
Abstract: PURPOSE:To obtain high efficiency and to reduce the power consumption and to improve the visibility by providing a picture element part which guides light out by a grating fitted to an optical waveguide. CONSTITUTION:The light from a light source 1 is guided in a selected channel optical waveguide C and guided in branch optical waveguides CD selectively by plural optical switches SWM provided as to said common channel optical waveguide. Then the light is guided out by fitted gratings 8 and light is guided out of picture element parts S selectively to display a necessary image, characters, symbols, etc. The light is guided out of each picture element part S not by a grating which utilizes refractive index variation based upon electrooptic effect, but the fitted grating 8 with high efficiency, thereby directing the light to the outside from the optical waveguide CD. Consequently, the optical waveguide efficiency is improved, the power consumption is reduced, and the visibility is improved.

Title: Infrared imaging apparatus
Inventor: OISHI TOSHIHARU
IPC: G01J1/02
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To obtain an infrared imaging apparatus by which the degradation of an image due to a narcissus is prevented by a method wherein the position of an entrance pupil at an infrared optical system is made to agree with the curvature center (the spherical center) of a spherical surface at an infrared window. SOLUTION: On-axis infrared rays 9 which are incident from the direction of an optical axis 8 at an infrared optical system 2 are transmitted through an infrared window 1 which is composed of a part of a spherical surface, and they are passed through the infrared optical system 2 so as to be condensed on an infrared detecting element 4. The output of the infrared detecting element 4 is converted into an image signal by an infrared image detector 3 so as to be output to the outside. The on-axis infrared rays 9 and out-of-axis infrared rays 10 agree apparently on an entrance pupil 13. On the other hand, since the spherical center 17 of the infrared window 1 agrees with the center 18 of the entrance pupil, the on-axis infrared rays 9 and the out-of-axis infrared rays 10 are faced with reference to infrared rays due to the reflection of the infrared window 1.  That is to say, a region in which the infrared detecting element 4 is visible due to the reflection on the surface of the window 1 is a region in which the front of the infrared detecting element 4 is cooled, and it is possible to prevent a narcissus from being generated due to the temperature difference of a visible object.
