Patent JP-S54103955-A (JP)
Title: Transmission with pinion
Inventor: KAMATA NAOKI
IPC: F16H1/06
Filed: 1978-02-03
Abstract: PURPOSE: To easily prevent stress from concentrating to a gear, by projecting the teeth of the gear like a cantilever from an end face of a cover for a one-way clutch and engaging the gear with a pinion.  
     CONSTITUTION: The rotation of the pinion 10 is transmitted to the gear 11a and picked out through the one-way clutch 6 and an output shaft 4. The opposite-pinion gear end of an outer member 71 for the clutch is extended in the axial direction when the outer member is formed, thereby making an extended part 71a. After the one-way clutch 6 is fitted in the outer member 71, the clutch cover 81 is calked inside the outer member. Since a small projection E 2  is made on the bottom land of the gear 11a by the calking, the stress concentration can be prevented without making a crown form on purpose. If the length of the extended part 71a is made not less than a half of the thickness of the extended part, that length is enough to prevent the stress concentration.

Abstract: PURPOSE:To accurately polish the flat surface of a glass plate, by balancing its residual stress, which has resulted from the removal of a predetermined quantity of residual stress by etching, to strain which corresponds to a depth of cracking caused in the polished surface by the polishing of one side of the plate. CONSTITUTION:After the residual stress 21 of a roughly polished glass plate 1 is measured, it is finish-polished and the residual stress 23 near the surface of the plate is measured. Etching liquid corresponding to desired residual stress 22 is selected depending on the measured residual stresses 21, 23. An etching time for the etching liquid is determined. Etching is effected on the glass plate 1 by the etching liquid for the etching time. The other side of the plate 1 is also polished under the same condition. The flatness of the surface of the glass plate is thus heightened.

Title: Bat made of frp for baseball and softball
Inventor: MISONO KAZUNORI
IPC: A63B59/54
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To obtain a bat having an extremely large impact resilience and durability by interposing a weak boundary layer(WBL), as a bonding inhibiting layer, between layers of FRP material forming a pad body. SOLUTION: A weak boundary layer(WBL) 6 is interposed between FRP layers 5, 5 forming a bat 1 made of FRP. The layer 6 is preferably disposed at a ball hitting portion of the bat 1, but it can be extended as far as a shaft part. One WBL layer 6 is disposed; however, two or more layers may be arranged. The layer 6 is formed by stacking a releasable film material 6A made, for example, of polyethylene and the like. Thus, flat rigidity can be made smaller by using the layers 6 to enhance a trampoline effect, and hence impact resilience can be improved to send a ball far away to a distance. By satisfying SG reference value of the FRP bat, required strength can be ensured.
