Title: Method for measuring origin of image, and its recording medium
Inventor: KATOU KOUICHI
IPC: G06T7/00
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of measuring an image origin, by updating blinking coordinates at a position or on a flat surface of an object to be tested from position coordinates of the object and observation information of a visual sensor, and measuring and verifying the origin in all the coordinates on an image surface. SOLUTION: All pixels on a liquid crystal display are processed or flashed. Then, after an observation area in a camera visual field is decided, starting coordinate point for obtaining a standard deviation distribution is decided. With end points of arbitrary two line segments with the starting coordinate point on an image surface as a bisecting point used as observation points, corresponding points are formed on the display. A projecting center is calculated by using positional information of the corresponding points of the two line segments and observation information of the two line segments by the camera. A combination of the two line segments is altered, and an observation point is altered at each predetermined pitch. A resultant standard deviation distribution is calculated.  Since a definition of the origin is coordinates of a foot at the time of falling a vertical line to an imaging surface from the camera projecting center, the coordinate position of standard deviation minimum is output as the origin.

CONSTITUTION:A diaphragm valve type carburetor has a jet needle 41, which vertically moves inside a needle jet 17 forming a fuel passage from a diaphragm chamber to a venturi in order to adjust the fuel flow rate, at a part, which faces a throttle valve 4, of a main body 1. In this case, a plurality of machined-off flats 42 are arranged along the outer periphery of the jet needle 41. In addition, the machined-off flats 42 are formed so that the clearance 43 between the bore of the needle jet 17 and the jet needle 41 gradually increases downwards and at the same time the circular arc parts 44 of the jet needle 41 and the needle jet are rendered to be slidable against each other. Due to the structure as mentioned above, the jet needle 41 can be prevented from staggering by the vibration developed with the operation of an engine and at the same time the fuel flow rate can be properly controlled, because the cross sectional area of the clearance 43 can be changed with the vertical movement of the jet needle 41.

Filed: 1983-10-24
Abstract: PURPOSE:To effectively form two-color lens of different colors by one process of injection by a method in which a thick portion and a thin portion are formed in the middle portion of upper and lower lens moldings leading to each other. CONSTITUTION:Injection molding of resins of different colors is made by using a mold having a thick portion 22 as a molten resin trap and a thin portion for regulating the flow of molten resin on its middle, and upper and lower lens- forming sections 20 and 21 on its both sides. When the resins of different colors are injected through nozzles 3 and 4, both resins are packed into the upper and lower lens forming sections 20 and 21 and joined in the thick portion 22 through the thin portion 23 to become an integrally melted resin. Since the flow of the resin is regulated in the thin portion, the inflow of different color of resin to the other lens forming section can be prevented.

Title: Heat treatment of silicon wafer
Inventor: ISHIKAWA SHIN
IPC: H01L21/324
Filed: 1992-07-03
Abstract: PURPOSE:To generate lattice defects of high density and many types sufficient to perform a gettering effect even in a wafer having low initial oxygen concentration or a wafer externally diffused with oxygen at a high temperature by conducting special first and second steps of heat treating. CONSTITUTION:Lattice defects are generated in an Si wafer by heat treating the wafer. In such a heat treating method, a single crystal Si wafer is heated at a temperature range of 400 to 500 deg.C at least for 5 hours. Then, the wafer is heated at a temperature range of 600 to 700 deg.C at least for 20 hours. Thus, since precipitated nuclei of oxygen are formed in a high density by the heat treating of the first step, the precipitated nuclei can be grown by the heat treating of the second step. Accordingly, the defects can be generated efficiently in a high density even in the wafer having a low initial oxygen concentration or the wafer externally diffused with oxygen.
