Title: Pattern defect detecting method
Inventor: WAKITANI KOICHI
IPC: G06T7/00
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To classify and accurately detect various pattern defects by detecting an object pattern which is different from a conforming article pattern as a defect pattern and classifying and detecting defect patterns according to features of the outlines of defect patterns. SOLUTION: An object image is inputted first. Then it is compared with the conforming article image which is previously registered. Then points which are on the outline of one of areas of the conforming article pattern and object pattern and do not overlap with the other area are detected and when the points are similar points, points which do not come into contact with two points are detected as contacts. Further, continuous areas which do not overlap with each other in both the areas are extracted as defect patterns. The number of contacts in a defect pattern is counted and detected and defects are classified by the number of contacts and detected. Consequently, various pattern defects can accurately be classified into, for example, a short circuit, a disconnection, a pattern residue, pattern peeling, chipping, thinning, etc., and detected.

Abstract: PURPOSE: To manufacture the easily openable metallic cover at high production rate with a compact equipment, by intermittently rotating a transferring board provided with holding sections of numerous metallic cover blank along its circumference, and by performing opening pressure-contacting of a pull, heating, etc., at every stop position.  
     CONSTITUTION: Plural holding sections 16 are installed to a rotary transferring board 8 at regular intervals along the direction of the circumference. When the transferring board 8 is intermittently rotated, a metallic cover blank 9 is transferred from a rotary disk 10 to the transferring board 8 at a stop position A and the blank 9 is tied to a holding tool 15.

Then, the blank 9 passes through a section where a high frequency induction heating coil is installed near a stop position C, and a pull is pressure-contacted to the blank 9 with a pull pressure- contacting device 25. When the metallic cover blank 9 passes through another high frequency induction heating coil 24 installed near the next stop position D, the fusion-contacted strength of the pull is increased. At a stop position E, the opening 4 and its vicinity and the pull are quenched and an easily openable metallic cover 1 is formed. When the metallic cover 1 reaches the next stop position F, the metallic cover 1 is pushed to the rotary disk 10 from the transferring board 8.

Filed: 1985-07-16
Abstract: PURPOSE:To enhance transient response and suppress an air fuel ratio fluctuation due to an individual difference, by causing a correction quantity before shifting to an open loop control region to be reflected without being changed, at the shifting from a feedback region. CONSTITUTION:When it is judged by a control unit 44 in terms of a load signal and a rotational frequency signal from a rotational frequency sensor 46 that the operation of an engine is in a feedback region, feedback control is performed on the basis of a feedback signal from an O2 sensor 30. At that time, a learnt value and a feedback correction value are calculated if a learning condition exists. If i is then judged that shifting to an open loop control region is performed, the basic fuel injection quantity at that time is corrected by the sum of the learnt value and the feedback correction value, calculated immediately before the shifting, to control the injection of fuel.

Filed: 1980-10-31
Abstract: PURPOSE:To increase mechanical strength without increasing the overall height, by installing a yoke bottom cover at a mounting bottom, and forming a concavity which is a play for both ends of a coil at the mounting. CONSTITUTION:A coil 73 to be wound on a bobbin is of double coil. Both ends of the coil 73a and 73b are put downward in radial direction, and included into a piercing hole of a mounting 1 through a play of a bottom cover 60. This enables enlargement of junction area between terminal plates 76 and 78 without increasing the overall height. The mechanical strength is increased and the local heating due to Joule heat is reduced. As notches formed on opposite side plates 58, 59 of a yoke are made smaller, the side plates 58, 59 are not weakened and hightened in magnetic efficiency. If a bimetal 82 is provided on the terminal plate 78, the rise from the mounting 1 bottom will obtain a sufficient effective length.
