Title: Thin film transistor
Inventor: YAMASHITA ICHIROU
IPC: H01L27/12
Filed: 1984-03-12
Abstract: PURPOSE:To reduce the punch-through capacitance by enhancing the light shielding effect by a method wherein the drain contact of the titled element is so formed as to envelop the source contact at least in part, and the drain electrode is so constructed as to cover also the channel region. CONSTITUTION:The structure that the drain contact 10 envelops the source contact 9 enables the increase in size of W and L and makes the source contact area smaller than conventional. In such a manner, no particular strict rules are necessary, but the shape of a constituent film is only changed; therefore, the process step does not increase. When the drain contact is provided on a common electrode scanning line and a common drain signal line, another area necessary to produce the transistor only has to be smaller because of the original necessity of the scanning and signal lines; thus, the picture element area can be increased by the reduction. Accordingly, the aperture efficiency of the display device improves.

IPC: B21B37/00
Filed: 1983-03-24
Abstract: PURPOSE:To keep the deviation of the sheet thickness of a material produced at the time of cutting it within the allowable limits by smoothing the change of a tension, added on the material, produced at the time of cutting during rolling by a shearing machine placed at the outlet side of a rolling mill placed at the final stage. CONSTITUTION:A rolling material 1 rolled by the mill 3 of final stage is wound up by the former of a pair of coilers 6, 7, and the sheet thickness of the material 1 is measured during winding by a detector 4, to control its sheet thickness basing on the detected results. The material 1 is cut by a traveling shear 5 when the quantity of wound-up material of the coiler 6 attains a prescribed value, and the front tip of a succeeding material is guided by the coiler 7 to start its winding. In this cutting, the timing of cutting by the shear 5 is predicted, for instance, by detecting the wound-up quantity of material 1 of the coiler 6 with the aid of a process computor, etc. Next, for preventing the sudden change of the winding tension of the succeeding material between the mill 3 and the coiler 7 caused by the cutting, the winding tension is changed in conformity with such a pattern which makes the set value of the winding tension, added on the material 1 before the prediction, to be approximately zero at the time of cutting.

Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To improve quality of a cold rolled metal strip by oscillating an angle which is formed by a center axis of a steering roll and the direction orthogonal to a line, in a prescribed variation width so as to prevent generation of a strip roll mark. SOLUTION: A metal strip 1 is rolled with a work roll 3 and a back up roll 4 of a rolling mill. A steering roll 2 is arranged in about 1000mm ahead of a rolling mill. For conducting meandering compensation control of the metal strip, meandering of the metal strip reaching from teens mm to tens mm is detected by a sensor, etc., meandering is instantly compensated by oscillating the steering roll 2 around the vertical axis or around the metal strip 1 flowing direction. An angle which in formed by a center axis of the steering roll 2 and the direction orthogonal to the line, is periodically and finely varied to change a strip route position, a level difference generating position for same strip width is dispersed. As a result, generation of a strip roll mark is prevented. By this method, an equipment modification on a large scale is not required.
