Title: Method for adjusting ion beam diameter, and ion beam generator
Inventor: SEKI TAKAYOSHI
IPC: H01J37/12
Filed: 1990-09-06
Abstract: PURPOSE:To enable arbitrary adjustment of ion beam diameter even when the ion beam energy is changed, by controlling the voltage applied between electrodes of a second accelerator in which at least three electrodes are sequentially stored along a path of ion beam and thereby adjusting the injected ion-beam diameter. CONSTITUTION:The ion beam 3 which has been emitted from an ion source 1 is accelerated by an accelerator 2 and is separated by a mass separation magnet 5 into specified ions alone which are accelerated by a succeeding stage of accelerator 6 for injection thereof. In the succeeding stage of accelerator 6, when a higher level of voltage is applied between the electrodes 6A and 6B, or between the electrodes 6B and 6C, the electric field intensity therebetween becomes high, whereby it is possible to make small the diameter phi of the ion beam 3. Conversely, when such voltage therebetween is made low in level, it is possible to make large the diameter of the ion beam 3. Accordingly, if the potential of the voltage being applied between each of the electrodes 6A to 6C for adjusting the ion beam diameter phiin value is determined in corresponding relation to the magnitude of the ion beam energy beforehand and is related thereto, it will be possible to operate a power source controller 8 on the basis thereof to obtain a desired ion beam diameter phi with a desired implanted energy.

Title: Printing method and device
Inventor: KARAKAWA KOICHI
IPC: B41F17/10
Filed: 1986-10-04
Abstract: PURPOSE:To print a pattern of varying repeat length on a running web without changing the diameter of a plate cylinder by comparing the distance between a set repeat length and a register mark and controlling the rotation of the plate cylinder based on an error signal of the distance. CONSTITUTION:A register mark 1 appears every one cycle on a running web 10 which is printed via a printing unit 50. This cycle is measured as a distance of the register mark by a distance measuring means 36, and a signal of the measurement value is transmitted to an arithmetic means 64. In the meantime, a signal of repeat length and a signal of distance which are set to a setting means 66 are compared and processed by the arithmetic means 64 to obtain an error signal. This error signal is sent to a control means 60, thereby adjusting the rotational speed of an electric motor 62 and obtaining a print of proper repeat length. Thus it is possible to print a pattern of varying repeat length on the running web without changing the diameter of the plate cylinder 42 substantially.

Title: Field chopper controller for electric railcar
Inventor: SAKAI HIDEO
IPC: H02P3/08
Filed: 1983-12-19
Abstract: PURPOSE:To effectively produce a regenerative power from an electric railcar by varying an initial brake speed in response to the variation in at least one of a trolley wire voltage signal and a brake force signal at a brake instructing time. CONSTITUTION:An initial brake speed detector 1A always monitors a speed signal and a trolley wire voltage signal, increases the initial brake speed when the trolley wire voltage is high at the brake instructing time and decreases the initial brake speed when the trolley wire voltage is low. Then, it reads out the speed signal when the brake command is inputted and produces a signal for turning a parallel/serial selection relay 2 ON when the read speed signal is higher than the initial brake speed and a signal for turning the relay 2 OFF when it does not exceed the initial brake speed. Since the parallel regenerative brake having good regenerative efficiency is operated in this manner as much as possible, the regenerative power can be effectively produced.

Title: Start controller for dc motor
Inventor: MITSUMATA MASATO
IPC: H02P7/298
Filed: 1990-09-07
Abstract: PURPOSE:To start a DC motor smoothly by varying the conduction ratio of a thyristor chopper from minimum value to maximum value during an interval after provision of a start command to the DC motor before elapse of an operation delay time inherent to an armature contactor. CONSTITUTION:Upon provision of a start command to a DC motor 2, field current is provided and at the same time the armature contactor 3 of the DC motor 2 is closed, where the armature contactor 3 has an inherent operational delay time. A constant time during which a conduction ratio varying means 22 varies the conduction ratio from minimum value to maximum value is set shorter than the operation delay time of the armature contactor 3. Consequently, a thyristor chopper 8 starts operation with minimum conduction ratio and field current is supplied with maximum conduction ratio when the armature 2A of the DC motor is fed with current.
