Title: Grinding method of semiconductor wafer
Inventor: HASHII TOMOHIRO
IPC: B24B37/00
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To reduce wafer production cost by accurately and efficiently grinding a semiconductor wafer after slicing and supplying the wafer to the next polishing step. SOLUTION: A semiconductor wafer 3 is ground roughly by a fixed whetstone between rotary whetstones 1 and 2. Subsequently to the rough grinding, fine grinding-grain suspended slurries are supplied to between the rotary whetstone wheels 1 and 2 from slurry piping tubes 4 and 5 to perform finish grinding with liberated grinding grains on the same grinding axis. When the finish grinding is performed with loose abrasive grains, the rotational and feed speeds of the whetstone 1 and 2 are reduced, to cause the grinding action of the fixed whetstone to be reduced.

Inventor: MASUDA KOUICHI
IPC: G01V8/12
Filed: 1980-12-05
Abstract: PURPOSE:To exactly inspect whether parts are present or not, irrespective of a color of a substrate and parts, by irradiating a fluorescent substance applied on a parts mounting position, etc. of the substrate by ultraviolet rays, and detecting a light emitted from the fluorescent substance. CONSTITUTION:On a parts mounting position of a substrate 2, an adhesive agent 15 containing a fluorescent substance is applied, and the respective parts 1 are fixed and mounted by the corresponding adhesive agent 15. When these adhesive agents 15 are irradiated by ultraviolet rays outputted from a lamp 16, the fluorescent substance in the adhesive agents emits an intense light beam, and its image is taken by a TV camera 8, etc. Accordingly, an intense light beam which is not influenced by a color, etc. of the substrate and parts is always photodetected, and whether parts are present or not are inspected exactly.

Abstract: PURPOSE:To shut out ghost, by forming a light outputting port and a light detecting body so that their shapes are approximately the same as the luminous fluxes of a beam at positions corresponding to light path lengths from the emitting position of the beam to an introducing port and to a measuring surface. CONSTITUTION:A body to be measured 13 and a photodetector 14 are provided in a symmetrical pattern on both sides of a central point C on the diameter of a reflecting body 10, whose inner surface is a semispherical mirror. A laser beam L from a laser oscillator 12 is made to pass through an introducing port 15 and inputted into the body to be measured 13. The reflected light is outputted to the outside through a light passing out port 16. A diameter D2 of the outputting port 16 and a diameter D3 of the photodetector are set as shown in the Expression in the Figure. The scattered light at a measuring surface is reflected with a semispherical mirror 11. The diameter of the luminous flux of each scattered light at the position of the photodetector 14 becomes the same as the diameter of the luminous flux of the beam L at the measuring surface 13a. Thus the light is condensed. When a diameter D1 of the beam is made to be the same as the diameter D3 of the photodetector, ghost, which does not go out of the reflecting body 10 through the port 16, advances at the outside of the photodetector 14 and is not detected.

Title: Diaphragm control device of camera
Inventor: YONEDA OSAMU
IPC: G03B7/08
Filed: 1983-09-19
Abstract: PURPOSE:To always obtain exact diaphragm control by correcting the error of an operation delay time of every interchangeable lens with a diaphramg detaining mechanism. CONSTITUTION:Resistances R'(DELTAAV), R''(DELTAAV) are set in accordance with a lens characteristic of every interchangeable lens. When a camera is released, the resistance value of the resistance R(AV) increases as a control plate 12 moves. Accordingly, the positive input terminal voltage of A6 rises. The outpu voltage of A6 goes to a voltage higher than the input voltage in accordance with a rising rate of its input voltage, and when a comparator A2 is inverted, a magnet Mg1 is conducted and the control plate 12 is detained, by which a diaphragm is controlled. Even if the time characteristic of a diaphragm variation is not a linear characteristic, when the time characteristic of the diaphragm variation advances early by a phase leading circuit, as a result, a diaphragm detaining signal is outputted earlier, and the exact diaphragm control is executed.
