Title: Ion generator
Inventor: TAKAYAMA KAZUO
IPC: H01J37/30
Filed: 1991-08-30
Abstract: PURPOSE:To generate ion beams of large current without increasing the ion temperature. CONSTITUTION:A sub-discharge chamber 5 for gas contact is provided between a main discharge chamber 1 and a main vacuum tank 11, while an extraction electrode 10 is provided in the vicinity of the sub-discharge chamber 5 in the main vacuum tank 11. A gas of the same kind as that for discharging is introduced into the sub-discharge chamber 5 as a gas for contact, through a passage 6. An electromagnetic coil 8 for plasma contraction is provided around the sub-discharge chamber 5. A plasma gas generated in the main discharge chamber 1 and the gas for contact introduced through the passage 6 are in contact with each other, and charge-exchange collision occurs thereby.

Title: Ground coil for magnetic levitation vehicle
Inventor: YOSHIDA TETSUO
IPC: B60L13/04
Filed: 1989-09-22
Abstract: PURPOSE:To prevent partial discharge regardless of some defect and to prevent dielectric breakdown even if the insulation layer is made thin by arranging such that an air gap is provided between the insulation layer of coil body and the floor when a flange section is secured onto the track bed. CONSTITUTION:Concerning to the bearing of potential between a coil conductor 1a and the track bed 4, almost all potential is applied onto the air layer in a gap G because the permittivity of an insulation layer 2 is about five times as high as that of epoxy resin. When the air gap G is kept at several mm, the air layer can withstand against voltage of 10 kv or higher. Almost all poten tial is applied onto the air layer but it causes no discharge with respect to the voltage applied onto the coil conductor 1a, and since the potential on the insulation layer 2 is low partial discharge does not take place even if there are some defects.

Title: Area working information generating device
Inventor: ARAO MASARU
IPC: G05B19/4093
Filed: 1988-09-29
Abstract: PURPOSE:To prevent over cutting in working and to attain automatic working pass formation by dividing an area curved line based on two cross points, which are obtained by the off-set of the area curved line, and executing the off-set of those divided curved lines to an internal side successively. CONSTITUTION:At first, an area curved line 12 is inputted by an area curved line input means 1. Next, the curved line 12 is off-set to the internal side by an area curved line off-set means 2. It is detected by a cross point detecting means 3 whether there are >=2 cross points in such an off-set curved line 26 itself or not. When there are >=2 cross points, two cross points 27 and 28 are connected with a straight line 29 in an area curved line dividing means 4 and the curved line 12 is divided into two areas 13 and 14 by a bisector 30 of the line segment 29. Then, the respective divided area curved lines 13 and 14 are stored to a storage device 10. After that, one curved line 13 in the means 10 is read and when the curved lines are not wholly taken out, the curved line 13 is successively off-set to the internal side by an off-set means 6. This operation is executed until the off-set is not executed ant more. Then, all the curved lines are regenerated as the working pass and operation is returned again to a next reading step. This operation is samely repeated up to the end.

Title: Microcomputer
Inventor: ITOKU OSAMU
IPC: G06F1/04
Filed: 1984-11-20
Abstract: PURPOSE:To reduce the electric power consumption and to obtain a microcomputer with a high stability and a high accuracy by executing the arithmetic processing at a high speed clock at the time of a normal action, acting at a low speed clock at the time of the action of a low electric power consumption and stopping a high speed clock oscillation. CONSTITUTION:In synchronizing with a CPU clock 12, a CPU 11 executes the arithmetic processing according to a program in a memory part 13. In accordance with a clock switching signal 19 transmitted from the CPU 11, a clock selecting part 14 switches either a basic clock 16 from an oscillating part 15 with a high frequency or a basic clock 18 from an oscillating part 17 with a low frequency and inputs it to a clock control part 110. When the signal 19 is transmitted and the clocks 16 and 18 are switched, an interrupting pulse with a narrow width arises, and therefore the control part 110 inhibits one clock immediately after the signal 19 has been transmitted from being inputted to the CPU 11 and inputs subsequent clock as a clock 12 to the CPU 11. When the CPU 11 acts in synchronizing with the clock 18, it stops the oscillation of the oscillating part 15 by a clock stop signal 111, thereby attaining a low electric power consumption.
