Title: Component mounting stage and hot pressure attaching device using stage
Inventor: NAKAJIMA HIDEKI
IPC: H01R43/00
Filed: 1993-08-23
Abstract: PURPOSE:To place a liquid crystal display panel on a hot pressure attaching stage at all times in the intended manner even though the thickness of the lower polarization plate of the panel differs. CONSTITUTION:In such a way movable up and down, an attraction stage 30 is installed in a runoff recess 24 provided on the surface of a stage body 23. When a lower protection film 10 of a liquid crystal panel 6 is placed on the stage 30, a coil spring 29 is elongated by the gravitational force of the panel 6 to cause the stage 30 to sink, and, the undersurface periphery of a lower glass board 7 of the panel 6 contacts the surface of the stage body 23. Therein the stage 30 sinks for an amount corresponding to the total thickness of a lower polarization plate 9 and the film 10. Accordingly the stage position in the vertical direction varies only in compliance with the thickness of the lower polarization plate 9 even though it differs, and therefore, it is possible to place the panel 6 on the stage 21 at all times in the intended manner.

Title: Semiconductor chip and its manufacture
Inventor: NAKAYA GORO
IPC: H01L21/301
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a semiconductor chip, which can separate the semiconductor chip from a semiconductor wafer without damaging it and by which fluid material is difficult to flow out in a manufacturing process. SOLUTION: In an RIE process, an interlayer film 42 of a chip isolation region 34 is removed in dot forms, and multiple small holes for cut assisting hole 90 are formed. Thus a resist which is applied later seldom flows into the holes for cut assisting hole 90. Recessed parts generated on the upper face of a first USG layer 44 formed on the small holes for cut assisting hole 90 are also in the from of the small dot. Thus, the large amount of an SOG layer 46 applied on the per face of the first USG layer 44 is prevented from flowing into the recessed parts. Even if cracks and the like occur at the time of cutting the semiconductor wafer, the advance of an occurred crack and the like can be stopped in any holes for cut assisting holes 90, 92, 94 and 96.

Title: Method for detection of elongation percentage in skin pass rolling
Inventor: ONO MASAO
IPC: B21B1/22
Filed: 1987-09-11
Abstract: PURPOSE:To shorten the elongation percentage output cycle and to improve the control accuracy even in case of a low speed operation by changing an elongation percentage measuring length of a steel strip in accordance with rolling speeds in detection of elongation percentages. CONSTITUTION:As for detection of elongation percentages in skin pass rolling, a measuring length of a steel strip is brought to be changeable in accordance with rolling speeds. For that, an arithmetic circuit 7 stores steel strip shifting amounts being a measuring length corresponding to rolling speeds. For example, respective lengths are determined so that 1m and 2m correspond to 100mpm and 200mpm respectively and the lengths are changed to 4m, 8m, 16m in accordance with speed acceleration. Shifting amounts before and after rolling are detected by speed detectors 8, 9 and an elongation percentage for a speed at that time is calculated by a prescribed equation. Hence, an elongation output cycle is reduced so that the control accuracy is improved.
