Title: Manufacture of chopstick material and chopstick material manufacturing device
Inventor: YAMAMURA YOSHIHIRO
IPC: A47G21/10
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To efficiently manufacture a chopstick material of a fractional material left over after making a semi-finished product of a WARIBASHI (disposable chopstick) using a back board as a remainder material. SOLUTION: First a flat board material 17c for making a semi-finished product of a WARIBASHI (disposable chopstick) is cut out of a back board with a crescent-shaped section obtained by sawing a log is its cutting face 12. Then a fractional material 17 of a specified length like a flat board which is as thick as the size in the width direction or less than the size of the half-split chopstick, is obtained. Further, the fractional material 17 is cut so that individual pieces of the WARIBASHI each having the size of a width equal to a single piece of the WARIBASHI are formed by an oblique face 17b inclined to the cutting face 12. Thus a flat board material 17c for a chopstick material 17a with the cutting face 12 and the oblique face 17b is produced.  The flat board material 17c for the chopstick material 17a is cut into the individual pieces of the WARIBASHI longitudinal at a specified pitch in the width direction of the flat board material 17 to finally obtain plural pieces of the chopstick material 17a.

Title: Coin collection device for automatic dispenser
Inventor: FUJITA SEIJI
IPC: G07F5/24
Filed: 1990-03-30
Abstract: PURPOSE:To automatically collect coins for change at the time of collecting them by providing a course switching means switching a system to a state where change is caused to flow to a change takeout port and a state where it is caused to flow to a collection place apart from the change takeout port in the change discharge course of a change discharge device. CONSTITUTION:At the time of selling a product, a slider 8 is moved and positioned so that the opening hole 81 faces the change takeout port 3 and change discharged from the change discharge device 23 one by one is dropped to the change takeout port 3. At the time of adding up sales, the slider 8 is moved and positioned so that the opening hole 8 faces a chute 7 and a coin from the change discharge device 23 is dropped from the chute 7 into a box 5. Consequently, a worker at the time of adding up can automatically collect the change coins in the box 5 only by leaving it as it is and executing other work after he gives the instruction of collection to the change discharge device 23. Thus, money-collecting work at the time of adding up can easily be executed.

Filed: 1990-03-31
Abstract: PURPOSE:To prevent required fault notification from being abandonned by stopping the fault notification from a slave monitor system at a much lower level before reaching the performance limit of a host monitor system. CONSTITUTION:When a fault is generated at a monitor object device 31-1, the fault is notified from a slave monitor system 20-2 to a host monitor system 10 and the fault is notified from a slave monitor system 20-1 to the host monitor system 10 as the faults of all monitor object devices 30-1-30-3, 30-6, 30-7 and 30-10 multiplexed at the monitor object device 31-1.

Inventor: WASHIDA AKIRA
IPC: F16C27/06
Filed: 1978-07-17
Abstract: PURPOSE:To improve the shock absorbing and buffer effect of a bearing, by fitting bearing pieces in an intermediate cylinder. CONSTITUTION:A rubber intermediate cylinder 5 has on its inner circumference dovetail grooves 7 to which bearing pieces 6 are fitted. The inner circumference of the bearing pieces 6 composes surfaces of contact 8 being in touch with the outer circumference of a shaft 1. As the shaft 1 is turned, fluid is forcibly fed on the surfaces of contact 8 due to the wedge effect and the pressure of the fluid film on the surfaces rises, which improves the PV value by raising the load carrying capacity of the bearing. Since the bearing pieces 6 are encircled by the rubber cylinder 5, they can improve the shock absorbing and buffer effect of the bearing.
