IPC: A63F7/02
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To dispense gift balls and lent balls through one game ball dispensing mechanism with distinction. SOLUTION: When a gear 45 starts rotating in the direction of an arrow YB, concerning a ball distributing mechanism 29, a disc 47 is rotated together in the direction of the arrow YB and until a projection 73 is abutted to a stopper 77, the disc 47 is rotated. When the projection 73 is abutted to the stopper 77, the rotation of the disc 47 is stopped but the gear 45 is continuously rotated. A valve 5 closes a gift ball side ball passage 25 so that all game balls 21 can be guided into a lent ball side ball passage 27. The rotation of the gear 45 is transmitted through a gear 43 and a gear G to a gear 37 and a rotary blade 35 is rotated in the direction of an arrow YA. Thus, the game ball 21 is sent out by the rotary blade 21 and all the game balls 21 are sent into the lent ball side ball passage 27.  When the gear 45 is rotated in the direction of an arrow YC, the game ball is sent into the gift ball passage 25.

Filed: 1989-06-23
Abstract: PURPOSE:To sufficiently increase the force to hold the material to be worked by freely setting the ratio of the force holding the material to be worked and the punching force and the incline surface of a cam driver and slide member. CONSTITUTION:When the driving member 14 is driven along the axial line L2 to the lower direction, the upper die 23 approaches the lower die 24, the stripper 15 is abutted to the material to be worked 22. When the driving member 14 is driven more, the 1st incline surface 13a of the cam driver 13 is abutted to the 2nd incline surface 18a of the slide member 18. Because the 3rd incline surface 18b of the slide member 18 is abutted to the 4th incline surface 19a of the punch 19, the driving force of the driving member 14 is worked through the cam driver 13 to the slide member 18. The material to be worked 22 is held to the die 11 with component force G by the stripper 15, pressed with component force N by the punch 19 and punched. Therefore the force to hold the material to be worked is sufficiently increased without making the die large size.

Abstract: PURPOSE:To calculate an accurate battery charge amount by holding a voltage of the battery before a radio equipment conducts transmission/reception for the transmission/reception execution period so as to detect the voltage in an optional timing regardless of the transmission reception timing of the radio equipment. CONSTITUTION:A voltage of a battery 1 is detected by a voltage detection circuit 2, and it includes a voltage drop in an internal resistance of the battery due to a large current caused at transmission in addition to a voltage drop through the current consumption as a whole. Furthermore, the transmission is interrupted for each prescribed time in a radio output of a time division multiplex communication equipment 6 and a comparatively large current is supplied from the battery 1, the voltage drop in response to the internal resistance is caused, resulting that an output of the circuit 2 is pulsative as shown in broken lines. A sample-and-hold circuit 3 provides an output of the circuit 2 to an A/D converter 4 when a timing signal (a) is at a low level and an output voltage of the circuit 2 is kept before the timing signal reaches a high level and fed to the A/D converter 4. Then the output of the circuit 3 is made constant from the start of transmission reception of the communication equipment 6 till its end.
