Title: Shaft for club
Inventor: KOBAYASHI MASASHI
IPC: A63B102/18
Filed: 1991-06-28
Abstract: PURPOSE:To prevent the compression breakage by the bending of a shaft without incurring the weight increase by the thickness increase of the shaft in the case that the hollow shaft of a club is made of material strong to tension and weak to compression. CONSTITUTION:In a shaft for a club such as a golf club, etc., the hollow shaft 11 is made to possess the tensile stress by blocking one end of the hollow shaft 11 and inserting a core material 14 shorter than the hollow shaft into the hollow shaft 112, and pressing the top of the bolt 12 screwed in the other end of the hollow shaft 11 against the end of the core material 14.

Title: Vibro-isolating mechanism for chain transmitting gear
Inventor: UEHARA KUNIO
IPC: F16H7/18
Filed: 1987-07-27
Abstract: PURPOSE:To promote the reduction of an impact noise by setting a position of an idler sprocket or a tensioner, pressed to the tensile side of a chain, in such a manner that a change of tension and that peculiar to a chain transmitting gear are negated by each other. CONSTITUTION:A chain driving gear 10 mounts an endless roller chain 13 to be wound between drive side and driven side sprockets 11, 12, and an idler sprocket 15, rotatably supported to a shaft 16 able to laterally and vertically move, is engaged with an intermediate position between both the sprockets 11, 12 in a tensile side 13a of the roller chain 13. The chain 13 generates in its tensile side 13a a change of tension in every movement of one pitch of the chain 13 but forcedly a vertical motion because the idler sprocket 15 is pressed, and the chain driving gear 10 sets this position in a manner, wherein a change of tension and that peculiar to the chain driving gear 10 are negated by each other, giving a change of tension in a reverse phase and removing the resonance condition. Thus quiet operation can be performed.

Filed: 1984-09-05
Abstract: PURPOSE:To eliminate a fault of electric short-circuit by forming an inner edge of a cylindrical metallic tube thinner than an outer edge so as to prevent a whisker from being in contact with electrodes of a vibrator of leads wires. CONSTITUTION:An outer diamter DA of the inner edge 11 of an inner edge 11 holding the vibrator 5 in a metallic tube 5 of an airtight ternminal is formed thinner than an outer diameter DB of an outer edge 13 at the boundary of a middle part 12. Then the vibrator 5 is bonded to a lead 3 of the airtight terminal and pressed into the outer pipe 1, then a whisker 10 is generated on the inner wall face of the outer pipe 1 opposed to the midpoint 12 being a boundary of the maximum outer diameter. In this case, since the inner edge 11 is formed thin, the whisker 10 touches the metallic pipe 2 and does not reaches the electrode and lead wire 3 of the vibrator 5.

Title: Quartz boat for diffusing impurity
Inventor: KAWASHIMA SADAMI
IPC: H01L21/22
Filed: 1986-08-07
Abstract: PURPOSE:To prevent a semiconductor substrate from breaking down by means of using a quartz boat partly or entirely coated with silicon carbide. CONSTITUTION:A quartz boat 1 is entirely coated with silicon carbide 3. When impurity diffusion on a semiconductor is performed in a quartz furnace core tube, the quartz boat 1 entirely coated with silicon carbide does not adhere to the quartz furnace core tube at all. When the quartz boat 1 is pulled out of the quartz furnace core tube after finishing the diffusion process, the quartz boat 1 not adhering to the quartz furnace tube can be pulled out of the quartz furnace tube very smoothly without giving a slight shock to the boat 1. Through these procedures, a semiconductor substrate is not subjected to any breakdown or shock etc. at all.
