Title: Production of photosensitive heat-resistant resin composition and insulating layer
Inventor: SHIBA SHOJI
IPC: G03F7/039
Filed: 1991-08-19
Abstract: PURPOSE:To practically realize a resin compsn. having photosensitivity and small film reduction due to heat treatment by dissolving a specified fluorine- contg. polyimide resin and acid producing agent in an org. solvent to prepare the photosensitive heat-resistant resin compsn. CONSTITUTION:This resin compsn. is prepared by dissolving a fluorine-contg. polyimide resin having the structural unit expressed by formula I and an acid producing agent in an org. solvent. In formula I, R1 and R2 are hydrogen atom, alkyl groups or alkyl-substd. silyl groups of 1-5 carbon number. However all of R1 and R2 are not hydrogen. This photosensitive heat-resistant resin compsn. is used to form a pattern. A polyimide resin to which F atom is introduced has such a property that resin is soluble in an org. solvent even after dehydration cyclopolymerization. By using this property, the fluorine-contg. polyimide resin is preliminarily subjected to dehydration cyclization in an org. solvent to have photosensitivity. Thus, the film reduction due to heat treatment can be avoided. Since this compsn. requires no resist for photographic etching, a highly-reliable insulating layer can be obtd. with decreased number of processes.

Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a hook structure for a tool with a handle, in which whether to utilize a hook protrusion of a hook body or whether to utilize a hook hole of the hook body can be decided depending upon the type of a hook part for a handle. SOLUTION: Hook holes 6, 11 are provided at an upper end 1a of a handle 1 having a grip part 2. A hook body 7 having a hook protrusion 10 is supported by the end 1a so as to be rotatable with respect to the part 2. As the body 7 rotates, it can take a hooking position A, where the protrusion 10 protrudes downward so that a hook recess 12 is formed between the protrusion and a top end 5a of the part 2, and a retracted position, where the protrusion 10 protrudes upwards so that the protrusion moves apart from the end 5a of the part 2. Thus, depending on the type of a hook part (bar 14 or hook) for the handle 1, whether to utilize the protrusion 10 by causing the body 7 to take the position A or whether to utilize the holes 6, 11 by causing the body 7 to take the retracted position can be conveniently selected. And when the holes 6, 11 are used, since the body 7 can be moved to the retracted position, when a grip 5 is held, the protrusion 10 of the body 7 does not become a hindrance and can be easily used.

Abstract: PROBLEM TO BE SOLVED: To appropriately judge whether a package is normal or not at the time of image recognition by calculating and comparing the rate of straight-line parts of outline data on the package with a criterion, and deciding whether the package is normal. SOLUTION: An image recognizing device 2 calculates the tilt and the center of gravity of an extracted seal ring in a horizontal plane from the outline data on the seal ring. The respective sides of the seal ring are determined by a method of least square from data which are present within a certain range roughly centering on the sides. Then, the image recognizing device 2 finds the rates of straight line parts of the outline data by the determined sides. Then the image recognizing device 2 compares the calculated rates of the straight line parts with the criterion inputted previously from a keyboard 9 to judge whether the package is normal or not. At this time, when a straight-line part is smaller than the criterion, it is decided that the package is a defective. Then this defective is automatically taken out by a carrying mechanism 4.
