Title: Photodetector
Inventor: HIRONISHI KAZUO
IPC: H01L31/10
Filed: 1987-02-19
Abstract: PURPOSE:To obtain a detector which has a high photoelectric conversion rate and high response speed by providing a polarizer and a junction type photoelectric transducer optically coupled to a Faraday rotor which rotates the plane of polarization 45 deg.. CONSTITUTION:Light from the polarizer 11 is projected to an incident face 12a of the Faraday rotor 12 and progresses in the rotor 12. The linearly polarized light progressing in the rotor 12 is rotated 45 deg. in the plane of polarization and is emitted from an exit face 12b from which the light enters the junction type photoelectric transducer 13 and is thereby converted to electrical energy. The remaining linearly polarized light which is not photoelectrically converted is projected through the transducer 13 to a reflecting mirror 14. The linearly polarized light projected thereto is reflected 14 and is partly converted 13 to electrical energy. The other linearly polarized light is entered through the transducer 13 to the rotor 12 by which the plane of polarization is rotated 45 deg.. The light emitted from the face 12a is projected to the polarizer 11 and is reflected 14. The incident light signal is passed back and forth twice in total through the part of the transducer 13 in such a manner, by which the device having the high photoelectric conversion rate and the high response speed is obtd.

Title: Manufacture of semiconductor integrated circuit device
Inventor: MURAO YUKINOBU
IPC: H01L21/304
Filed: 1987-02-18
Abstract: PURPOSE:To prevent the deterioration of the junction characteristics of a semiconductor element by removing an silicon oxide film through anisotropic dry etching and getting rid of a contaminant through O2 plasma treatment over the whole surface of an silicon substrate. CONSTITUTION:An anisotropic dry etching process is completed, and an silicon substrate is treated with oxygen plasma for approximately 100 min. sufficiently. Consequently, a contaminant including an etching-gas is taken off to approximately completeness from the exposed surface of an n<-> diffusion layer 4, and the substrate is purified. Accordingly, a diffusion into the n-diffusion layer 4 of the contaminant can be prevented even when the push-in treatment of an n<+> diffusion layer 6 is executed, thus effectively preventing the junction deterioration phenomenon of a semiconductor element due to the contaminant.

Title: Discriminating instrument for steam condensation
Inventor: HARADA HIROO
IPC: F28B9/00
Filed: 1980-03-21
Abstract: PURPOSE: To obtain the titled discriminating instrument, structure thereof is simple and which is small-sized and can be utilized for detecting a water level of a condensing reservoir, by a method wherein one end of an object of high thermal conductivity is contacted with a fluid to be discriminated as a heat absorbing section, and the flow rate of heat flowing to a radiating section of the other end is detected.  
     CONSTITUTION: When a heat absorbing section of a metallic bar 2 is disposed into steam in a condensing reservoir pipe 1, a fixed quantity of heat passes through the metallic bar 2 at all times and a thermocouple 7 continues to detect a uniform temperature because the heat absorbing section is heated continually by steam. When a water level of condensation in the pipe 1 rises and the heat absorbing section immerses in the condensation, however, heat around the metallic bar 2 is robbed of by the condensation, and temperature drops. Consequently, temperature shown on the thermocouple 7 also drops. As a result, steam and condensation can be discriminated. Thus, the titled discriminating instrument is obtained which is small-sized, simple in structure and easy to be mounted and can detect the water level of the condensation.
