Title: Skin bonded object and skin bonding method
Inventor: MIYAGAWA SHINJI
IPC: B29L23/00
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To increase the bonding strength of a skin due to fusion bonding and to easily and certainly produce a skin bonded object increased in bonding strength. SOLUTION: Bent end parts 31 are fusion bonded while regulating the flow of a molten resin from the fusion bonded part of the bent end parts toward a leading end to form a ridge part 32 to the boundary part of the skin main bodies 30 bifurcated in cross section from the bent end parts 31. Since the ridge part 32 is fusion bonded to a pair of the bent end parts 31 and a pair of skin main bodies 30, bonding strength is enhanced markedly.

Title: Inspecting instrument
Inventor: KAJIYAMA KOICHI
IPC: G01N21/94
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To accomplish discrimination between the adherence of a foreign matter to an overcoated layer and the formation of a protrusion made by the foreign matter included into the overcoated layer by identifying transmission light or reflected light from an object to be inspected as bright defect or dark defect. SOLUTION: When any foreign matter 36 adheres to an overcoated layer c, light is scattered on the foreign matter 36 to be dissipated to make an input signal into a sensor 8 dark in level. On the other hand, when a sunk part 37 is formed in the overcoated layer C, the light is scattered at the sunk part 37 to make the input signal into the sensor bright in level. When a foreign matter 35 is rolled into the overcoated layer C to form a protrusion, the protrusion part of the overcoated layer C functions as microlens so that the light passing through the layer is condensed slightly before the protruded defect and detected by a sensor as bright dot. On the other hand, the light surrounding the condensed part decreases thereby allowing detecting of the bright defect and the dark defect in a pair.

IPC: H01L21/78
Filed: 1987-05-08
Abstract: PURPOSE:To prevent wafer or Si scrap from adhering to the surface of an element and thereby to prevent the generation of defective devices by a method wherein a protecting sheet used in a breaking process is allowed to remain without being peeled off and a holding sheet is forced to expand. CONSTITUTION:Semiconductor wafers 1 are pasted to a holding sheet 3 and then subjected to a breaking process after the application of a protecting sheet 2. The holding sheet 3 is caused to expand, by thermal and mechanical means, with the sheet 2 retained on the wafers 1, for the wafers 1 to be given a prescribed separation between them. In this arrangement, the wafers 1 are prevented from producing new scrap that may be produced owing to mutual contact in a conventional design, and Si scrap 4 is kept between the wafers 1. The wafers 1 therefore do not collect wafer or Si scrap, which prevents the production of defective devices.

Abstract: PURPOSE:To enhance feed accuracy of perforated paper stopping various phenomena of resonance, bouncing, slip, etc., of a feed belt by arranging a pair of ring plates concentrically with a rotary shaft of a driving sprocket to be turnably built in both sides of this sprocket. CONSTITUTION:When a feed belt 2 floats its circular arc-shaped running part, a paper feed surface of this running part comes into contact with a friction wall of a ring plate 26, and it is rotated together with a driving sprocket 16 in its direction of rotation by friction force of both the feed surface and the friction wall. By this action of rotating together, a belt retainer 62, integrally formed with the ring plate 26, presses a linear running part of the feed belt 2 in a side opposite to its paper feed side. At the result, the feed belt 2 eliminates floating of its circular arc-shaped running part simultaneously preventing resonance and bouncing of the linear running part in a side opposite to the paper feed side of the feed belt 2. Accordingly, perforated paper enables its feed accuracy can be improved.
