Title: Electrode wire for electric discharge machining
Inventor: HASEGAWA NOBUYUKI
IPC: B23H7/08
Filed: 1995-02-17
Abstract: PURPOSE: To identify electrode wire types so as to increase workability by coloring the surface or entire cross section of an electrode wire for discharge machining. CONSTITUTION: Electrode wires for electric discharge machining include two types: one comprising base metal only and the other comprising a base metal on which a coating material is applied. Also a copper wire, a copper alloy wire, or a steel wire is used for the base metal, and copper, brass, or zinc is used for the coating material. Therefore, if the material only is used, it becomes dark color such as brown or gray. To prevent this, the base metal 1 is colored, or the entire cross section of the base metal is colored. Or one layer of the coating material 3 is applied to the base metal 2, and the coating material-3 is colored. It is desirable to color it with a bright color such as red, blue, or yellow. Thus the electrode wire is colored for identification even under discharge working environments.

Title: Measuring device for physical properties of plasma
Inventor: AOKI YOSHIAKI
IPC: G01N21/21
Filed: 1985-02-19
Abstract: PURPOSE:To improve measuring accuracy by projecting linearly polarized light to a plasma, detecting S and P polarized components radiated from the plasma, and measuring a plasma temperature on the basis of both the components. CONSTITUTION:A light source 30 is connected to a reference power supply 31 and light flux having prescribed light source luminance is radiated from the light source 30. The light flux radiated from the light source 30 is converted into parallel light flux through a collimeter lens 32 and the linearly polarized light of the component S is transmitted by a polarizer 33 and projected to the plasma 3 through a condenser 34. The projected light is converged in the plasma 35, then made incident upon a detector device 38 through a slit 36 and a condenser 37. The S polarized component and the P polarized component are separated from each other by a beam splitter 41 in the device 38, detected by respective photodetectors 43, 47 and inputted to an arithmetic processor 45. The processor 45 calculates the plasma temperature on the basis of the S and P polarized components. Thus, the plasma temperature on the same space can be measured at the same time and the measuring accuracy can be improved.

Title: Production for liquid crystal display element
Inventor: OKAJIMA HIDEAKI
IPC: G02F1/1341
Filed: 1984-02-21
Abstract: PURPOSE:To seal up a cell without charging air in the cell by applying an adhesive to a liquid crystal charging entrance of the liquid crystal cell, to which a liquid crystal is charged, in vacuum and leaving the cell at a room temperature to cool the cell and leading the adhesive into the cell by contraction of the liquid crystal and irradiating ultraviolet rays in this state to harden the adhesive. CONSTITUTION:Peripheral parts of light-transmittable electrode substrates 1 and 2 are stuck to each other by a seal material 3, and a liquid crystal 6 is charged from a liquid crystal charging entrance 4, which is formed in the part to which the seal material 3 is not applied, in a vacuum atmosphere. This liquid crystal cell 5 is heated at 40-50 deg.C, and a sealing adhesive 7 hardened by ultraviolet rays is applied to the charging entrance 4 in vacuum. The cell 5 is left and cooled at room temperature to lead the adhesive 7 into the cell 5 in accordance with contraction of the liquid crystal 6. In this state, ultraviolet rays are irradiated to the adhesive 7 to harden the adhesive 7, and thus, the cell 5 is sealed up. Thus, air is prevented from being charged into the cell at the adhesive applying time, and degradation of the adhesive strength due to air 9 between substrates and the adhesive penetrating the cell and deterioration of display due to air bubbles 10 in the liquid crystal layer are prevented.

Title: Engine exhaust emission control system
Inventor: TAKAMI AKIHIDE
IPC: F02M25/07
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To sufficiently regenerate a catalyst and stably ensure good NOx removal performance, while minimizing aggravation of fuel economy and other ill effects in an exhaust emission control system A provided with a lean NOx catalyst in an exhaust passageway of an engine that absorbs NOx and sulfur contents when oxygen concentration is high in exhaust emissions and discharges NOx when oxygen concentration is low. SOLUTION: A feedback correction is made (SC8, 9, 10) of the amount of fuel injection according to a signal provided by an O2 sensor to bring an air-fuel ratio to a point near a stoichiometric ratio if the temperature of a catalyst is high (SC4, 5) when the catalyst is evaluated as being poisoned by sulfur based on an operating history of an engine. At the same time, the injection of the fuel is done in two steps, one in an intake stroke and the other in a compression stroke (SC11). When NOx is discharged from the catalyst, the feedback control of the amount of fuel injection and two-step fuel injection are performed likewise. The catalyst is of two-layer coating and zeolite is supported on the outer catalytic layer.

Abstract: PURPOSE:To accurately decide the presence/absence of a solder bridge by using general light by irradiating a subtrate with scattered light at an angle at which no reflected light of the scattered light is directly inputted to an image pickup part, and performing the arithmetic processing of image data between obtained soldered parts. CONSTITUTION:An illumination part(ring shape fluorescent lamp) 20 illuminates the inside of the visual field of an image pickup camera 10 in the neighborhood of a printed board 40 from the outside at a shallow angle. Therefore, the reflected light from a plane in parallel with the surface of the board 40 is scarcely inputted to the camera 10. However, the reflected light from the plane such as the surface of the solder bridge is inputted to the camera 10 with sufficient light quantity. The image data from the camera 10 is A/D-converted 31, and is stored once in an image memory 32. The data in an inspection area out of stored 32 data is read with a prescribed timing by a CPU 33. The CPU 33, after performing filtering on the image data, performs binarization, and finds the area of a solder bridge part. The CPU 33 compares the area with an permissible value stored in a built-in memory, and decides the presence/ absence of the solder bridge.
