IPC: F02M61/18
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To prevent deflection of an orifice plate to which a fuel pressure is applied by reinforcing the orifice plate of a fuel injection valve for an internal combustion engine using a simple construction.

Abstract: PURPOSE:To make it possible to easily detect a defect even when the defect involves a large amount of specular reflection components, by a method wherein, above an aluminum plate, such spot-like light sources that they are reflected in the surface of the aluminum plate are arranged in a lattice shape. CONSTITUTION:An aluminum plate 7 having roll streaks 9 shows specular reflection characteristics in a direction parallel to the roll streaks 9 and diffuse reflection characteristics in a direction orthogonal to the roll streaks 9. Spot-like light sources 10 are arranged in a lattice pattern above the aluminum plate 7. As a result, striped light and dark patterns are formed on the surface of the aluminum plate 7 in a direction orthogonal to the roll streaks 9. If a defect 12 is present on the surface of the aluminum plate 7 at positions 11d, 11e where the dark pattern is reflected, the illuminating light L1 from the light source 10d shows reflection characteristics in which specular reflection components are large in amount at the damage 12, so that the damage 12 is brightly seen from an observation position 8. In this case, if the mounting height of the light source 10 is represented by H, the mounting distance La is set at 0.04H or less, while the mounting distance Lb is set at 0.8H or less, whereby it is possible to easily detect the defect.

Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To obtain a structure which can improve selectivity of an oxide film to the organic photoresist film of an etching mask at etching of the oxide film, etc. SOLUTION: A process chamber 30 of an inductively coupled plasma etching system is provided with a plate 34, which is extended in parallel with the top wall 32 of the chamber 30 and made of Si or SiC and a low-frequency power source 36, which impresses a low-frequency voltage of 400-800 kHz upon the plate 34.

Abstract: PROBLEM TO BE SOLVED: To facilitate mounting/demounting work of a surface plate, by providing a vacuum device mutually sucking a polishing surface plate and a surface plate receiving part so that the surface plate and the surface plate receiving part integrally formed can make a relative motion relating to a wafer. SOLUTION: In a surface mounting a surface plate 14 of a flat plate part 12a in a surface plate receiving part 12, a groove-shaped vacuum passage 15 for vacuum sucking the surface plate 14 is formed.

Title: Setting method of switching temperature of heat sensing semiconductor switch
Inventor: TADA AKIHARU
IPC: H01L35/00
Filed: 1979-08-17
Abstract: PURPOSE:To readily set the switching temperature of the SCR to be set by utilizing the fact that the gradients of the temperature dependence of the breakover voltages are approximately equal in the vicinity of the switching temperature. CONSTITUTION:A reference element 1 and an element to be set 2 are connected in parallel, and the temperature is set at a switching temperature of the reference element. At this time, the resistance RGA2 between the gate and anode of the element 2 is low, and the breakover voltage is high. Therefore, the current is not flowed in an anmeter 3. When the thick film resistor RGA2 is cut by the sand blast and the like and the resistance value is increased, the breakover voltage is decreased, and the current flows in the anmeter 3 at last. At this time, when the adjustment of the resistance is stopped, the breakover voltage of the element 2 coincides with that of the element 1, and the setting of the switching temperature has been completed. In this constitution, the adjustment is simple, the switching temperature can be set very easily, and the constitution is suitable for the mass production.
