Patent JP-H07326319-A (JP)
Title: Ion implanting device
Inventor: TOKIKUCHI KATSUMI
IPC: H01J37/317
Filed: 1994-05-31
Abstract: PURPOSE:To provide a compact device by providing a speed reducer of ion beam energy between an ion source and a mass separator, and keeping the beam transporting space between the ion source and the speed reducer at a negative high voltage. CONSTITUTION:Attention is paid to the negative voltage space between an ion source 1 and a speed reducer 5. Ant ion beam collides with a residual gas or wall within this space to generate a large quantity of secondary electrons. However, the secondary electrons are carried on a mass separator 2 side having a high voltage. Thus, the secondary electrons which neutralized the space charge of the ion beam in this space is eliminated, the ion beam is highly diverged by its own space charge, and collided with the wall in the space to loose the current. Since the beam aperture is also increased by the divergence, the beam transmitting efficiency of the speed reducer 5 is also reduced. To prevent the outflow of the secondary beams, an electrode having a voltage lower than the negative voltage of line space is arranged as one of the electrode voltages of the speed reducer 5, whereby the outflow can be prevented. Thus, the effect of neutralizing the ion beam space charge by the secondary electrons can be kept.

Title: Hydrogen nuclear fusion method
Inventor: NOBUNAGA HISASHI
IPC: G21B3/00
Filed: 1989-05-11
Abstract: PURPOSE:To obtain a hydrogen nuclear fusion reaction at a low temp. with the simple device by using the simple substance of a metal, such as, for example, alkaline metal, rare earth element or Sc or V for a cathode material which impresses voltage between a pair of electrodes immersed in heavy water. CONSTITUTION:The heavy water 2 and a small amt. of metal salt are filled in a vessel 1 and an anode 3 and cathode 4 consisting of gold are immersed at an adequate spaced interval therein. The voltage is impressed between the anode 3 and the cathode 4 from a constant voltage power source 5. The bubbles of hydrogen appear on the surface of the lanthanum (La) cathode 4 and the deuterium ions having positive electricity are absorbed in the electrodes in an initial period if the La is first used for the cathode 4 of this constitution and, for example, 20V is impressed between the anode 3 and the cathode 4. Neutrons, gamma rays and heat generation are then observed. Any metals which can form a metal hydride are usable as the cathode 4 material. Metals having a high hydrogen density when converted to the metal hydride, for example, lanthanum, vanadium, magnesium, etc., are preferable for the above- mentioned material.

Title: Curled cable
Inventor: SUZUKI EIJI
IPC: H01B7/06
Filed: 1994-05-31
Abstract: PURPOSE:To provide a curled cable excellent in restoring property by curling a coaxial composite multi-core cable in the same direction as the cable collecting direction, followed by reversing the curl completion direction opposite to the cable collecting direction. CONSTITUTION:A conductor 1 is covered with an insulator 2, followed by application of a shield layer 3. And then, insulated electric wires each consisting of conductor 5 covered with an insulator 6 are collected, to be covered with a suppressing winding 7 and a polyester elastomer sheath 8. Consequently, a coaxial composite multi-core cable can be manufactured. The coaxial composite multi-core cable is tightly wound around a round rod counterclockwise, i.e., in the same direction as the collecting direction, followed by heat-setting with heat. The cable is cooled, and then, the winding direction is opposite to that the curl completion direction is reversed in the collecting direction, thereby completing the curling process. As a result, it is possible to provide a curled cable capable of exhibiting an excellent restoring property even if it is elongated six or seven times.

Title: Non-contact power supply type traveling truck
Inventor: FURUKAWA SHOHEI
IPC: B60L5/00
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To make it possible to always supply power with less variation even if a traveling course includes straight course and curved course by mounting an opening section of an iron core winding a pickup coil thereon so as to direct to the peripheral surface side of the curved course of a traveling rail.

When the traveling truck 10 is driving forward from a straight course to the curved course 14A, since the opening 32A of the iron core 32 is opened toward the peripheral surface side of the curved course 14A, a distance interval between an induction line 30 and the iron core 32 is short in comparison with the center of the iron core 32, and since the pickup coil 34 approaches the induction line 30, magnetic coupling between the pickup coil 34 and iron core 32 is tightly closed.  Accordingly, power is supplied without dropping voltage induced to the pickup coil 34. As a result, power with less variation can be always supplied.

Filed: 1981-07-30
Abstract: PURPOSE:To reproduce solid parts and fine image parts faithfully without being affected by environmental changes by using a rotary brush body for sticking of a powdery non-magnetic insulating toner by frictional charging. CONSTITUTION:When a rotary brush body 1 is rotated in the direction opposite from a photosensitive drum 4, the body 1 rubs a ''Teflon '' brush 1b and a toner 3. The electrostatically charged toner is stuck to the brush 1b and is conveyed. During the course of the conveying, the toner is charged electrostatically to an arbitrary polarity by a corona charger 5. Thereafter, the toner developes the latent image formed on a photosensitive drum in the developing position in contact with the drum 4. Since each particle of the toner stuck to the brush 1b is charged surely to a positive or negative electrode, photographic fogs are eliminated. In such a way the solid parts and fins image parts are reproduced faithfully without being influenced by environmental changes.
