Inventor: FURUKAWA MOTOHIDE
IPC: G06Q30/06
Filed: 1989-12-28
Abstract: PURPOSE:To simplify reservation control by displaying the contents of an inputted reservation as a new reservation if the contents are not the same as already reserved contents, and if the new reservation is not utilized up to a prescribed period, canceling the reservation. CONSTITUTION:In the control device 1, reserved contents are inputted to a processor 3 by operating an input device 2, and when the contents are already reserved, reservation invalidity is outputted to a monitor. When the acception of the reservation is available, 'reservation acception available' is outputted to the processor 3 and the contents are displayed on a reservation/using state display board 7 and a ticket issuing machine monitor 11. A user can directly offer the reservation by issuing a reservation ticket from a ticket issuing machine 8. The contents to be inputted are a telephone number, using date and time, a using place, the distinction of a user's address in the city or not. When the processor 3 can receive the reservation, a reservation ticket is issued. The user pays the charge of the ticket before the prescribed period to purchase a using ticket from the machine 8. When the reserved contents inputted to the machine 8 coincide with the contents concerned, a payment request is displayed on the monitor 11, and when the charge is injected, the using ticket is issued. If the using ticket is not issued up to the period, the reservation is canceled by a canceling circuit 6 based upon the contents of a timer device 5. Thus, the reservation control can be simplified.

Title: Ion implantation device
Inventor: NAKAZAWA MAKOTO
IPC: G21K1/14
Filed: 1993-12-15
Abstract: PURPOSE:To prevent implantation pollution of a target caused by metallic ions other than the intended ions. CONSTITUTION:A stripper canal 7 of a charge converting part is covered with a protective layer 12. The protective layer 12 is formed of an ion generating construction material by which an orbit of an ion in an electromagnet does not coincide with an orbit of an object ion when the generated ion enters an energy analyzing electromagnet by being accelerated by a high energy side accelerating tube 8 by sputtering the layer when a negative ion beam from a low energy side accelerating tube 6 strikes against it. The protective layer 12 is, for example, a carbon layer, and even if it is sputtered by the anion beam, a generated carbon ion is separated and removed by the energy analyzing electromagnet. The stripper canal 7 is directly sputtered by the negative ion beam, and a target can be prevented from being polluted by generated metallic ions.

IPC: H03K3/356
Filed: 1992-12-22
Abstract: PURPOSE:To obtain a general-purpose flip-flop circuit(FF) by devising the circuit so as to be operated by either rising and falling edge of a clock signal. CONSTITUTION:When an enable signal E is made to 1, an in phase signal P and an inverting signal inverse of P are made to an opposite value to that of the time when the enable signal E is made to 0, and a synchronizing signal generating circuit corresponds a rising change of a clock signal CK from 0 to 1 to a falling change of an in phase signal P from 1 to 0. That is, a DFF fetches data inputted to a terminal D at the trailing edge of the clock signal CK and outputs inverted input data to a terminal QN. The synchronizing signal generating circuit converts the clock signal CK by the control of the enable signal E into a negative lock signal CN and the general-purpose performance is improved by inputting data at the rising edge and outputting the data at the falling edge.
