Patent JP-S63225745-A (JP)
Title: Toothed timing belt
Inventor: FUTAMURA KAZUMASA
IPC: F16G3/10
Filed: 1987-03-12
Abstract: PURPOSE:To avoid the breakage and cutting of a tooth due to the separation of a seamed portion of a canvas as a surface member, and improve the durability of a belt, by inclining a direction of a seam line of the seamed portion at a predetermined angle relative to a tooth trace and locating a part of the seam line on a tooth flank other than a bottom land and a root of tooth. CONSTITUTION:A canvas 3 to be bonded by curing to a rubber 5 and formed into a tooth profile of cylindrical internal teeth is seamed cylindrically. A seam line is inclined at a predetermined angle theta relative to a direction of a tooth trace in such a manner that the angle theta is not less than a critical angle theta0 defined according to a width (FE) of a belt 1 and a width (FH) of a bottom land B and that a part of the seam line is located on a crest A of the tooth profile. Accordingly, the seamed portion intersects a root C of tooth at one point, thereby reducing the influence of a repeated stress. Even if a thread of the seam line at the root C and the bottom land B is partially cut by the influence of the repeated stress, the seam line at the crest A of the tooth profile is not damaged to prevent the seamed portion of the belt from being entirely separated. Thus, the belt is prevented from being cut during operation, and normal operation can be continued owing to the superior durability.

Title: Wafer positioning mechanism
Inventor: SUGISHIMA KENJI
IPC: H01L21/68
Filed: 1985-03-19
Abstract: PURPOSE:To contrive the improvement in the exactness of positioning operation by enabling the positioning even if there is unevenness in a circumferential part of a wafer at the positioning of a mounting position prior to the processing of a wafer of semiconductor and etc. CONSTITUTION:The second roller 5 is added. When a wafer W is rotated, a contact force to a roller 3 of the wafer W is enhanced by a pressure of the roller 5 and a frictional force increases so that it can be prevented that the rotation of wafer W stops before it reaches a predetermined position as in a conventional device even if there is unevenness due to a resist on a circumferential part of the wafer W. As the roller 5 is located on the opposite side to a guide pin 2 with respect to the line connecting the center of wafer W present in a predetermined position and that of the roller 3, the component of force in lateral direction in the drawings which acts on the wafer W sandwiched by the rollers 3 and 5 is directed toward the guide pin 2 so that the wafer W does not levitate from the guide pin 2 at rotation.

IPC: H01R13/633
Filed: 1994-03-25
Abstract: PURPOSE: To obtain a connector that doesn't cause connection interruption between a memory card and a personal computer even if misoperation, unexpected impact, or vibration occurs. CONSTITUTION: When a push bar 36 attached to housing 12 of a connector 10 is moved to a front part 76a, a sliding plate 28 engaged from the push bar 36 through a turn lever 34 moves to a backward 76b while pushing a memory card.
