Abstract: PURPOSE:To provide a change collection structure for an automatic vending machine which turns a coin return chute toward a separate area concurrently with movement of a cashbox to a change falling area and can easily collect the coins stored in a coin processor into the cashbox. CONSTITUTION:When a cashbox 11 which collects the coins stored in a coin processor 7 moves to a change falling area A, the cashbox 11 hits the side face of the main body 81 of a coin return chute. Under such conditions, the pressing force applied to the side face of the body 81 effectively serves as the turning force of the body 81 because the body 81 is connected to the shaft 82 of the body 81 via a connector arm 83 with a distance secured between the body 81 and the shaft 82. As a result, the body 81 turns toward a separate area B against the energizing force of a spring 10. At the same time, the cashbox 11 can easily move to the area A.

Title: Dc power supply switch gear
Inventor: MORI SADAJIRO
IPC: H02M7/06
Filed: 1989-03-27
Abstract: PURPOSE:To permit the application of a small-sized switch on a high voltage or a bit current and prevent the title device from becoming a large size by interrupting a current by utilizing the current blocking effect of a diode. CONSTITUTION:When a load current is to be interrupted, first and second switches 5A, 5B are opened. When the polarity of a terminal A is positive, first and fourth diodes 1, 4 are conducted and, therefore, the first switch 5A generates arc but the second switch 5B is opened without generating any arc since second and third diodes 2, 3 are not conducted. Next, current tries to flow through the second and third diodes when the polarity of the terminal B has become positive, however, the circuit is disconnected by the second switch 5B and, therefore, said diodes can not be conducted and the interruption of the current may be completed. Further, arc is generated in the first switch 5A but the second switch 5B will never be conducted since the current is blocked by the diode 1. The diodes help the interruption of the switches and, therefore, the switches may be miniaturized.

Abstract: PROBLEM TO BE SOLVED: To make the valve itself in a small size, as well as to prevent the generation of a cavitation, in a rotary valve. SOLUTION: To a valve body 4 provided rotatable around the axial center of a valve shaft 3 inside a valve box 2, an upstream side valve body 6 to block an upstream side port 2a; a downstream side valve body 7 to block a downstream side port 2b; and an opening 8 to communicate the upstream side port 2a and the downstream side port 2b, in the flow passage opening time; are formed, and comb teeth form parts 9 and 10 are provided to the end edges parts of the upstream side valve body 6 and the downstream side valve body 7 which proceed following to the valve closing operation. As a result, since the pressure reduction of a fluid is burdened by the comb teeth form parts 9 and 10, the differential pressure per one point is reduced, and the generation of a cavitation or the like is suppressed. Furthermore, since the upstream side valve body 6 and the downstream side valve body 7 are made in the form expanding rotatable inside the valve box 2, the striking of the cavitation to the inner surface of the valve box 2 is hardly generated, and the valve body can be made smaller than a conventional same valve.
