Inventor: NOMURA TOMOMICHI
IPC: A63F7/02
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent ball clogging in the upper ball tray of pachinko machine. SOLUTION: When game balls are stored in the upper ball tray, this is detected by a ball detector and corresponding to this detection, an electric motor 71 starts rotating under the control of controller. Thus, an operating member 74 repeats reciprocative turns with a supporting shaft 73 as a center, and a hitting element 74a at the top end collides with an upper surface part 22 and applies vibrations. Therefore, even when the smooth flow of game balls is disturbed by making dirty the surface of upper surface part of upper ball tray because of the long-time use of pachinko machine or partially recessing the surface because of the weight of stored game balls, the vibrations are applied to the upper surface part. Thus, the stop of game balls is excluded, the game balls are continuously supplied, idle hitting due to a ball shooting device is prevented and smooth play can be secured.

Filed: 1981-05-27
Abstract: PURPOSE:To avoid bad effect on the sheet thickness control by reducting hysteresis in a roll cross rolling mill, by retaining roll chocks movable in the direction of drawing down force through a rolling contact sliding device. CONSTITUTION:When worm jacks 10 and 10' are respectively actuated in opposite directions by the same quantities in a roll cross rolling mill, the movements of them are transmitted to a roll chock 2 through pusher bars 8 and 8' so as to make the axial line of a roll 1 cross an imaginary line which intersects the rolling direction perpendicularly. Further the chock 2 is retained between pusher guides 9 and 9' and chock plates 11 and 11' through wheels 12 and 12' and roller bearings 13 and 13', to be made movable in the direction of drawing down force. Thus, the whole frictional resistance in the direction of the drawing down force is reduced even under a large thrusting force by utilizing the rolling contact to reduce the coefficient of friction.

Title: Equi-velocity joint
Inventor: HOSHIKAWA FUMIO
IPC: F16D3/227
Filed: 1988-03-30
Abstract: PURPOSE:To reduce the extent of internal frictional force in an equi-velocity joint by dislocating a rolling part of a ball moving along a groove of an inner ring and a partial spherical surface in the axial direction, respectively. CONSTITUTION:A ball 20 is inset in space between a groove 11 of an inner ring 10 and a groove 3 of an outer ring 1, while a partial spherical surface 12 is formed in an outer diametral surface of the inner ring 10, and the partial spherical surface 12 and a rolling part 13 of the ball 20 are dislocated each in the axial direction. With this location, since an offset value ranging from the center of an inner diametral spherical surface 33 of a cage 30 being engage with the partial spherical surface 12 to the angle center of a joint can be taken larger, internal frictional force in the eqi-velocity joint is reducible. Consequently, improvement in such characteristics as induced thrust force, slide resistance, temperature rise, service life and so on is well promotable.

Filed: 1988-03-30
Abstract: PURPOSE:To avoid the influence of the hit of a circuit without deteriorating the performance of the multi-address communication by setting a delay circuit including a memory at the front stage of a transmission circuit. CONSTITUTION:The information to be multi-addressed is supplied to the delay circuits 2-1 and 2-2 via an information input part 1 and stored in the memories 5-1 and 5-2 via the memory control parts 4-1 and 4-2. These stored information are transferred to the transmission circuits 6-1 and 6-2 via the control parts 3-1 and 3-2. In this case, a time difference t1 is given to the transfer timing between the information transferred to the circuits 6-1 and 6-2 via the circuit 2-2. The information transferred to the circuits 6-1 and 6-2 are transmitted through antennas 7-1 and 7-2. The radio waves set at different frequencies and polarized wave surfaces by the circuits 6-1 and 6-2 and the antennas 7-1 and 7-2 are transmitted for redundant multi-address. The value of the delay time t1 is set by a statistic means at a level smaller than the information transmission time T and larger than the instantaneous interruption time t2. Thus it is possible to obtain the same information after the time t1 despite of the occurrence of the instantaneous interruption.

Title: Manufacture of semiconductor device
Inventor: NAKASAKI YASUSHI
IPC: H01L21/28
Filed: 1987-04-02
Abstract: PURPOSE:To keep stable, low resistance contact characteristics and wiring characteristics, when a high melting point metal film is formed on a silicon layer or a silicon substrate, by constituting a laminated structure of a high melting point silicide film, a high melting point metal nitride film and a high melting point metal film by a self-alignment manner. CONSTITUTION:After only high melting point metal on silicon is silicified by a heat treatment, a part, which is not silicified, is selectively removed. Then a part of a high melting point metal silicide is nitrided. Thus a double-layer laminated structure of a silicide film 111 and a nitride film 110 is formed. Then, a high melting point metal 112 is selectively deposited on the laminated structure. In the high melting point metal laminated film formed in this way, the diffusion of silicon atoms from the nitride film 111 or silicon is suppressed with the nitride film 110 even if the device is made to pass through high temperature steps. The silicification of the high melting point metal film 112 as the uppermost layer is prevented. The low resistance value as pure metal is kept in the high melting point metal film in this way. The nitride film 111 can keep excellent contact characteristics with the silicon. Furthermore, the laminated films are formed in a self-aligning manner. This method is suitable for miniaturization without a photoetching technology.
