Title: Oil film detecting device
Inventor: HIRAOKA MUTSUHISA
IPC: G01N21/21
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To separate the water surface from an optical system for reducing the influence of the scattering of water due to waves and to achieve a stable measurement by logarithmically converting the P-polarized component of reflected light and the quantity-of-light signal of the S-polarized component before subtraction. SOLUTION: Each quantity-of-light signal of a P-polarized component 13 and an S-polarized component 14 that are optoelectrically converted by photodiodes 15 and 16 are logarithmically converted by logarithm amplifiers 27 and 28 and then are subtracted by a subtraction circuit 29, thus obtaining a logarithmically converted polarization ratio. As a result, even if the incident angle of application light is small ranging from 45 to 60 degrees and the quantity of light of the P-polarized component 13 of reflected light is close to zero, the evaluation of the polarization ratio can be made by subtracting the signals of the P-polarized component 13 and the S-polarized component 14, thus eliminating the need for any division near zero and hence preventing unstable operation and stably calculating a polarization ratio.  Therefore, since the incident angle of application light can be reduced, the water surface can be separated from an optical system without increasing the optical system, thus reducing the influence of the splashing of water due to waves.

CONSTITUTION: Before LOCOS using a silicon nitride film 7 as a mask is executed, a resist layer 4 having an opening corresponding to a region wherein an element isolating film is to be formed is formed on a silicon substrate l and an impurity of high concentration is implanted with the resist layer 4 used as a mask. After the resist layer 4 is removed, a second oxide film 5 is formed by utilizing an action of increasing the speed of oxidation by the impurity, and a recessed part is formed in the region on the surface of the silicon substrate l wherein a first oxide film 6b is to be formed, by removing the second oxide film 5. The first oxide film 6b for isolation of an element is formed thereafter by the ordinary LOCOS.

Title: Phase order switching circuit of three-phase voltage
Inventor: KADOGAKI TAKANOBU
IPC: H02H7/097
Filed: 1992-05-21
Abstract: PURPOSE:To switch and connect an electric motor to match the phase order of a three-phase power supply without requiring a manual wire switching operation. CONSTITUTION:When three-phase power supplies R, S, and T are introduced between AC input terminals A and G of a rectification circuit 1 as illustrated, a difference occurs in a rectification output of the rectification circuit 1 depending on whether the phase order of the power supply is in constant relationship or not and it is detected by a zener diode. When the phase order is not in a constant relationship, a transistor 3 continues to drive a relay 4 for automatically switching to match the phase order of the power supply according to the contacts 4a-4d.

Title: Multipoint analog input circuit
Inventor: MAEKAWA YOSHIZO
IPC: G08C19/30
Filed: 1989-05-24
Abstract: PURPOSE:To enable measurement with high accuracy without being affected by stray capacity by providing a precharge circuit, which precharges the stray capacity of an output part by using the analog input voltage of each point for each scan of each point, for each channel. CONSTITUTION:For each channel, a precharge circuit 2 is provided to precharge stray capacity Cx of the output part by using the analog input voltage of each point each time the respective points are scanned. Thus, since a charge accumulated in a capacitor C1 of an input circuit 1 is not charged to the stray capacity Cx, and the drain and source voltage of an FETF1 to be used for an analog switch is made equal when the FETF1 is turned on and off, charge injection quantity caused by the joint capacity of the FETF1 is canceled and further, by inserting suitable resistance R3 to the output of the precharge circuit 2, the offset voltage of an amplifier AP for precharge is not accumulated in the capacitor of the input circuit. Thus, even when a scan period is changed, the stable voltage measurement can be executed.

Abstract: PURPOSE: To carry out efficient deodorizing as well as to prevent generation of secondary public nuisance by using an aqueous solution containing chlorine dioxide in a low conc. adjusted to an alkaline side as a gas deodorizing chemical liquid.  
     CONSTITUTION: A concn. of chlorine dioxide in a chemical liquid to be used is appropriately determined by a kind of an exhaust gas, a kind and a concn. of a malodorant substance but, practically, it is about 10W1,000ppm. Further, a PH of said liquid is adjusted to an alkaline side of about 7W9 and, as an alkali agent, for example, caustic soda, caustic potash or the like are used. This chemical liquid is used in a known gas-liquid contact apparatus or the like to carry out the deodorizing of a malodorant gas and chlorine dioxide is finally decomposed to HCl and H 2 O and, because formed HCl is neautralized by said alkali agent, secondary public nuisance to a water discharge system is not generated.

Title: Manufacture of prepreg
Inventor: TSUNODA GOROU
IPC: B29B11/16
Filed: 1983-07-15
Abstract: PURPOSE:To obtain prepreg having a few remaining solvent and no gap among fibers, by contacting an article to be treated, which is made of arranged fibers impregnated with thermosetting resin, with heating gas through a counter current while the article is being touched to a heating unit having a curved surface and run. CONSTITUTION:Thermosetting resin such as unsaturated polyester resin or epoxy resin is applied to a unidirectional reinforcement fiber made of glass fiber or carbon fiber. On the one hand, as for a heating unit combining arranged fibers and a releasing paper surface, various units such as a one having a lower surface only at a horizontal surface and both ends or non-contact type one are used. As for the surface against which the releasing paper abuts, a box heater which is covered with a metallic plate and is efficient toward a counter current of hot air is desirable. As a temperature in the vicinity of an inlet of the heater is made low so that sudden solvent evaporation does not occur there, gaps among fibers are eliminated.

Title: Picture display controller and picture display control method
Inventor: TOYODA SHINJIRO
IPC: G09G3/20
Filed: 1992-04-23
Abstract: PURPOSE:To obtain a picture display controller in which the shape of picture is not distorted even if it is moved at a boundary between two scanning regions. CONSTITUTION:The picture display controller holds picture display position information in a second position holding means 109. A comparing means 106 detects that the output of the final line of a picture is finished, and by using the signal as a timing signal, picture display position information held in the second position holding means 109 is transferred to a first position holding means 104'. The transferred signal can be used as an interruption signal to MPU. Since a next picture position is rewritten by a timing signal indicating the finish of outputting whole line of the picture, the shape of the picture is not distorted even if a picture being present on a boundary between an upper scanning region and a lower scanning region is moved.

Title: Vortex flowmeter
Inventor: TANIMURA YOSHIHIKO
IPC: G01F15/00
Filed: 1989-05-23
Abstract: PURPOSE:To stabilize a flow and to enable stable, high-accuracy flow rate control by providing a 1st contraction part which reduces fluid flowing out of a downstream cover, a straightener, and a 2nd contraction part formed on the downstream side of the straightener. CONSTITUTION:A funnel part (1st contraction part) 11b projects from the honeycomb straightener 14 of a conduit 11 to the upstream side, i.e. into an air cleaner 2 and is provided only at the opposite part of the downstream cover 22 from an element 23, and it is so shaped as to reduce the fluid toward the intake of the conduit 11. The fluid flows in the air cleaner 2 and reaches the intake of the conduit 11, i.e. honeycomb straightener 14, but the flow direction of the fluid along flow stream lines F1 - F3 is corrected, so that the fluid passes through a bell mouse part (2nd contraction part). In this process, the flow stream line F3 is increased in speed by the contraction effect of the funnel part 11b. Consequently, the flow velocity distribution in the conduit 11 right before a vortex generation column 12 is uniformed. Consequently, the flow of the fluid becomes stable to generate vortexes normally, thereby improving the flow rate measurement accuracy.
