Title: Variable winning ball apparatus of pinball game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1987-08-03
Abstract: PURPOSE: To eliminate the deformation of a prize probability regulating member by the collision of a shot ball so that the shot ball can be guided to a special prize hole at a scheduled probability even after long-time use by forming a special prize hole forming member of a synthetic resin having an impact strength higher than a mounting base. CONSTITUTION: A special prize hole forming member 120 mounted on the front surface of a prize ball receiving frame 45 is formed of a plate guide plate 122 and a pair of prize probability regulating members 123a, 123b integrally formed vertically to the guide plate 122. As the synthetic resin constituting a variable prize ball device 40 including a mounting base 41, an ABS resin is used.  However, since the special prize hole forming member 120 receives not only balls falling on a rolling surface 52 as prize balls, but also has a relatively high ratio that the balls taken by rotating pieces 48a, 48b are directly fallen to the prize ball receiving frame 45 without fallen on the ball guide surfaces 50a, 50b of a member 50, and a consideration is thus required so that the member 120 is never deformed by the impact force of the falling prize balls, a polycarbonate resin having further high impact strength, compared with the ABS resin, is used for the member 120.

Title: Optical fiber for parts
Inventor: TANAKA TAIICHIRO
IPC: G02B6/00
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To provide only small relative distortion eve if smaller bending is added and to improve mechanical reliability by providing an optical fiber previously with a prescribed bending radius. SOLUTION: The optical fiber is provided with the prescribed curvature radius at the time of producing it. A viscosity difference is caused in a melting stage between the specified side of an optical fiber base material and an opposite side, for example. Concretely, the viscosity difference is caused by adding dopant to the optical fiber base material itself. The obtained optical fiber having the prescribed curvature radius is made into a coil form by winding it around a bobbin having the preset smaller curvature radius. Since the optical fiber is n a state where it originally has bending, the degree of bending is required to be small compared to a straight optical fiber even if it is made into the coil of smaller curvature. Thus, stress caused on the surface of the fiber can be reduced and mechanical reliability is made superior.
