Title: Oil film detecting device
Inventor: HIRAOKA MUTSUHISA
IPC: G01N21/21
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To attain continuous automatic monitoring of a very small amount of oil content with high sensitivity and accuracy by irradiating light beams including both polarization elements of P, S to a water surface, and obtaining the light quantity ratio of the both polarization elements from its reflected light for comparison with a reference value. SOLUTION: From a laser light source 1 having circularly-polarized light characteristics, light beams 4 including a P polarization element (polarization element in the vibrating direction 2 of P polarization element) and S polarization element (polarization element in the vibrating direction 3 of S polarization element) equally are irradiated to a wavy water surface at an incident angle 7, which is floated with an oil film 5. A reflected light 10 is passed through a polarized beam splitter 12, and after separation into the P polarization element 13 and the S polarization element 14, respective light quantities are converted into electric signals by photodiodes 15, 16. After the electric signals are amplified respectively, the light quantity ratio of the both elements 13, 14 are computed and outputted by an arithmetic circuit 19.  The signal is moving-averaged and is compared with a reference value at the time of normal condition which has no oil film 5 on the water surface, by a comparing circuit 24. If it exceeds a preset range, it is discriminated that the oil film is present, thereby outputting an alarm 26.

Abstract: PURPOSE:To prevent the formation of hillocks, to decrease cracks in a passivation film and to improve reliability, by providing a wiring layer wherein an uppermost aluminum alloy wiring layer is constituted with an aluminum alloy film incorporating at least silicon and a silicide film grown on the alloy film. CONSTITUTION:Aluminum silicon alloy 3 having a thickness of 0.5-2.0mum in which 1% silicon is added and tungsten silicide 4 having a thickness of 0.05-0.3mum are sequentially deposited on a silicon substrate 1, whose surface is covered with a silicon oxide film 2, by a sputtering method. Then, the tungsten silicide 4 and the aluminum alloy 3 are continuously etched by using a lithography technology. After an aluminum wiring alloy wiring is formed, phosphorus glass 5 is deposited as a passivation film by a CVD method. In this way, even if the deposition is performed at a high temperature of about 400 deg.C, hillocks are never formed.

Abstract: PURPOSE:To obtain a semiconductor device having high integration density and less manufacturing error by utilizing first and second polycrystalline silicon resistance materials. CONSTITUTION:The first polycrystalline silicon resistance material 4 formed on an oxide film 8 on the silicon substrate and the second polycrystalline silicon resistance material 5 formed after thermally oxidizing said first polycrystalline silicon resistance material are formed adjacently. Thereafter, a contact 3 is opened and a combined resistance material is formed by a leadout conductors 1 and 2 and mutual connecting conductors 6 and 7. Because there is an oxide film 10, electrical continuity is not assured between the first polycrystalline silicon and the second polycrystalline silicon. Therefore, about doubled resistance can be formed in the same area.

Abstract: PURPOSE:To reduce a return light quantity and to improve an S/N ratio of a detecting signal, by changing a phase quantity of a 1/4 wavelength plate placed on an optical path, by a phase quantity generated by anisotropy of an information carrying body. CONSTITUTION:Laser light emitted from a laser 1 passes through a collimating lens, passes through a beam splitter 5 as a elliptical polarized light A and becomes linear polarized light B in the (y) direction.

Its light is reflected by the polarized light beam splitter 5, becomes signal light 1 and is made incident to a photodetector 16. Linear polarized light B and D fall at right angles with each other, therefore, the return light quantity is reduced and the S/N ratio is improved.

Abstract: PURPOSE: To make cycle time shorter, adsorbents less and productivity high in a chromatography by decreasing the rate of supply of the adsorbents and superposing the parts of low concn. in the leading and trailing end parts of the solute of an adsorption band on the adjacent adsorption bands.  
     CONSTITUTION: In the stage of supplying a mixture and adsorbents alternately by using a column packed with the adsorbents such as zeolite, and separating an intended component from the mixture by utilizing a difference in adsorptive power, the parts of low concn. in the leading end part and/or trailing end part of the adsorption band for the intended component are superposed on the adjacent adsorption band parts by putting many hours and without supplying any  adsorbent in order to obtain a small amt. of solute and adsorption and desorption are carried out. The generation of large deviations in a chromatographic  curve is obviated by the superposition of the leading and trailing end parts, and  there is no influence in the recovery of the intended component. Although the  yield per cycle decreases, the time for one cycle is reduced, the amt. of the used adsorbents is decreased considerably and productivity is improved on the contrary.
