Title: Bearing structure
Inventor: TOTSUKA YUKITAKA
IPC: B29L15/00
Filed: 1990-02-28
Abstract: PURPOSE:To prevent internal burr from interfering a shaft, which is inserted in a through hole, and make it possible to smoothly rotate the shaft in a bearing part without being affected by the internal burr by a method wherein the internal burr, which develops at the parting line in the bearing part during molding, is produced at the recessed part, which is developed by molding shrinkage, on the wall surface of the through hole. CONSTITUTION:When a gear 20 is injection-molded, at the thick part, at which a rib 22 is provided, of a bearing part 21, molding shrinkage develops and wall surface sink generates. Accordingly, at the central position on the wall surface 26 of a through hole 25, recesses 40 due to the molding shrinkage amount are produced. On the other hand, the parting line 27 of the bearing part 21 is also produced at the central position of the wall surface 26. Accordingly, burr 42 produced 26 the parting line 27 does not project beyond the wall surface at by the amount of the depth of the recess 40. As a result, by making the height of the internal burr 42 smaller than the depth of the recess 40, the occurrence of interference between the bearing part 21 and a shaft inserting in the bearing part 21 due to the internal burr 42 is eliminated.

Filed: 1990-02-28
Abstract: PURPOSE:To prevent electrostatic breakage in manufacturing process by removing a semiconductor layer in the same process with the selective removal of a protection film after the protection film is deposited on the surface of a transparent substrate, and disconnecting the short-circuited wiring. CONSTITUTION:Semiconductor layers AS and DO which connect the short- circuited wirings GSW and DSW decrease in resistance value through photoconducting operation when irradiated with light, thereby short-circuiting the short-circuited wirings mutually. Namely, the short-circuit wirings are short- circuited mutually by irradiating the semiconductor layers with the light throughout the process wherein a lower transparent glass substrate SUB1 is taken out of the jig of a CVD device after the protection film PSV1 is deposited by a plasma CVD method which easily generates static electricity in manufacturing the liquid crystal display device. Consequently, an electrostatic breakdown between a scanning signal line and a video signal line, a source electrode or drain electrode and a gate electrode, etc., is precluded.

IPC: G11B21/08
Filed: 1986-03-05
Abstract: PURPOSE:To improve data transfer speed by providing two sets of the access means consisting of an arm and head on a disk and overlapping a seeking motion and the read and write motions of data between the access means. CONSTITUTION:Two sets of the arms 21, 22 having a head on the disk 1 are provided to discriminate whether the zone exists on mutually different cylinder when the data of plural zones are read and written on the disk 1 or not. In case of belonging to different cylinder, the disk controller simultaneously gives the prescribed command like seeking for the nearest cylinder to the arms 21, 22. For instance, the read and write motions are commanded when a seeking motion is completed before by the arm 21 and the succeeding motion is commanded after its completion. The arm 22 performs the same motion as the arm 21 so that the time necessary for the seek is offset by the read and write time. In this way the time loss is reduced and the data transfer speed can be improved.
