Title: Trepanning tool
Inventor: SHIMOMURA HIROSHI
IPC: B23B51/04
Filed: 1983-06-15
Abstract: PURPOSE:To prevent a tool main body from being curved and improve precision of a hole by arranging cutter tips in such a manner that backside component force working on each cutter tip nearly compensate with each other. CONSTITUTION:The captioned tool is formed in such a manner that backside component force from the outside to the inside works on two cutter tips 15a, 15c of four cutter tips 15a, 15b, 15c, 15d, while the same force from the inside to the outside works on two other cutter tips 15b, 15d. Then backside component force working respectively on the tips 15a and 15c compensate with each other, while the same force respectively working on the tips 15b and 15d also compensate with each other, and a resultant force of backside component forces is not generated at all. Accordingly, curvature of the tool main body 11 is prevented and precision of the hole is improved.

Title: Ball-receiving pan for pachinko game machine
Inventor: KITAMURA TETSUO
IPC: A63F7/02
Filed: 1994-04-22
Abstract: PURPOSE:To increase the capacity of a ball-receiving pan without preventing the flow of balls. CONSTITUTION:In the bottom surface of a ball-receiving pan 11, a part excepting a guide passage 14 to an exit 13 is configured with a movable bottom plate 15. The movable bottom plate 15 is supported so that it can incline up and down with a shaft 18 as a fulcrum by supporting the downstream end (exit 13 side) of the movable bottom plate 15 with the side wall of the ball-receiving pan 11 via the shaft 18. The upstream end of the movable bottom plate 15 is elastically supported using springs 16. As the amount of pinballs in the ball- receiving pan 11 increases, the weight presses the movable bottom plate 15 down against the resiliency of the springs 16 and the inclination of the movable bottom plate decreases. This decreases the back pressure per pinball to adequately control the back pressure level applying to pinballs around the exit 13, preventing pinballs from forming an aggregative population to cause jamming around the exit 13 an advance.

Title: Magnetic tape cassette
Inventor: MORITA KIYOO
IPC: G11B23/087
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To remove foreign matters inside the guide groove, and to smooth and stabilize the operation of the opening/closing cover by forming, on a slide pin projectingly provided inside the side plate of the top lid, a foreign-matter discharging through-hole which extends in the axial direction including and on the side opposing the face of a groove for guiding the slide pin in slidable contact. SOLUTION: The slide pin 2 projectingly provided inside the side plate 4 at both ends of the top plate 10 of the top lid 3 is inserted so as to make it slidable in a guide groove formed on the front upper part on both sides of the upper half of a magnetic tape cassette. On the slide pin 2, a foreign-matter discharging through-hole 5 is constituted which is provided with an inlet 15 on the side opposing to the slidable face on the lower side of the guide groove. With the slide pin 2 sliding in contact with the face of the guide groove, the lower end edge 12 collects foreign matters entered in the guide groove and discharges them outside from an outlet 5a. Consequently, sliding resistance of the slide pin 2 is reduced, enabling the operation of the top lid 3 to be stabilized.
