Title: Synthetic resin retainer for ball bearing
Inventor: MISHIMA KENICHI
IPC: F16C33/44
Filed: 1987-02-04
Abstract: PURPOSE:To eliminate misassembling by providing projections extending in the direction of the principal axis of a bearing between adjacent retaining portions, thereby guiding a steel ball to an inlet opening position of the retaining portion. CONSTITUTION:Projections 2 extending a little over the top surfaces of tongue- piece portions 1b, 1b in the principal axis C of a bearing are provided between the tongue-piece portions 1b, 1b of adjacent retaining portions 1, 1. At the time of assembling a retainer R, even if the position of an inlet opening 1a of the retainer is shifted from the position of a steel ball B, the ball B is guided to the inlet opening 1a of the retaining portion on either side of the projections 2 by the projections 2 to be pressed in the retaining portion 1. Accordingly, defective goods will not be produced so as to completely eliminate the possibility of misassembling.

Title: Holder device utilizing quick release tool of bicycle
Inventor: MIURA KAZUYUKI
IPC: B62J11/00
Filed: 1988-02-04
Abstract: PURPOSE:To enable small articles to be fixed by easy operation to a bicycle body further to be released from the fixing by utilizing a quick release tool. CONSTITUTION:When a quick release tool 3 turns its cam lever 18 in a lock direction, a space between a pressing unit 14 and a pressing surface of a holding unit 21 decreases. Here the pressing surface of the holding unit 21 is adapted to a fork end 2, strongly pressing it. Since length of a fixing pin 24, slidably inserted into a through hole 23 of the holder unit 21, is larger than the length of the through hole 23, the pin 24 receives reaction force of the pressing force from the fork end 2, being forcedly intruded from the pressing surface of the holder unit 21 in a manner wherein one end of the pin protrudes to the internal surface of a holding hole 22. An article A, inserted into the holding hole 22, is forcedly pressed by the fixing pin 24 to an internal wall in an opposite side, and the article A is fixedly held into the holding hole 22 by this pressing force. On the contrary, when the cam lever 18 is turned in a lock release direction, the article A can be removed from the holding hole 22.

Title: Laser oscillator
Inventor: UENO NOBORU
IPC: H01S3/093
Filed: 1986-02-06
Abstract: PURPOSE:To excite the surface of a laser medium in a wider range than ever by means of excitation light which is reflected by an elliptic converging/reflecting mirror and heads for the focal point on the other side of the mirror and to decrease the polarization of excitation by providing the position of the focal point on the outside shifted from the center of the laser medium. CONSTITUTION:An excitation lamp 2 is placed in such a way that the center of that coincides with the focal point A of an elliptic converging/reflecting mirror 3 and a laser medium 1 is not placed its center on the focal point B on the other side of the elliptic mirror but is placed approaching the excitation lamp 2 on the major axis of the elliptic mirror within a range that the focal point on the other side of the elliptic mirror is included within the range of the laser medium 1. In such an arrangement, the light to pass through in such a way as to be emitted from the excitation lamp 2 and come into contact to the laser medium 1 comes to reach up to E and F points on the inner side compared with the case of conventional laser oscillators after being reflected by the converging/reflecting mirror 3. This effect becomes a maximum when the laser medium 1 approaches the excitation lamp 2 until the focal point B coincides with the surface of the laser medium 1, and at this time, the whole surface of the laser medium 1 comes to be irradiated with the excitation light.
