Title: Finishing work through electrolytic working
Inventor: KUWABARA YOHEI
IPC: B23H3/02
Filed: 1988-02-13
Abstract: PURPOSE:To surely discharge the working chips and electrolytic liquid from a gap between a work and an electrode by continuously suppling the jet stream of the electrolytic liquid into the gap through a hole on the work or the electrode for a prescribed time during the feed of the pulse or OFF-operation of the pulse and spreading the gap during the feed of the electrolytic liquid after the OFF-operation of the pulse. CONSTITUTION:A single pulse is supplied between an electrode 2 and a work 4 which are set oppositely, keeping a prescribed gap 19, through an electrolytic liquid. During the feed of the pulse into the gap 17 or at least for a prescribed time from the OFF-operation of the pulse, the jet stream of the electrolytic liquid is continuously supplied into the gap 17 through a hole 15 formed on the work 4. After the pulse is set OFF and during the feed of the jet stream of the electrolytic liquid, the gap 17 is spread. Therefore, the cut chips such as the electrolytic products in the gap 17 which are eluded because of the feed of the pulse is discharged outside the gap 17 by the eddy current of the electrolytic liquid, and the electrolytic liquid between the work 4 and the electrode 2 is exchanged with the fresh electrolytic liquid, and the working condition for all the worked surface is made uniform.

Title: Lighting system utilizing solar light power generation
Inventor: HIGUCHI NOBUYUKI
IPC: F21S2/00
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a lighting system utilizing a solar light power generation excellent in a design capable of sufficiently realizing a harmony with a surrounding and realizing a compact size and a cost reduction. SOLUTION: The lighting system is a foliage plant type illumination device for decoration. The device uses a device case 22 accommodating a solar battery cell 6, a storage battery 12, a light-emission source 16, etc., as a pot for plant. First and second light transmission parts 8b are bundled to make a branch of plant. Leaves 30 branched from the branch have a shape that a light- collection part and a light-emission part are superposed at a laminar shape. The light-collection part has a function for collecting a solar beam and making the beam incident to the solar battery cell 6 through the first light-transmission part 8b. A current generated in the solar battery is temporarily accumulated in the storage battery 12.  When the light-emission source 16 emits a light making the storage battery 12 as a power source, the light is incident to the light- emission part having a light permeability through the second light-transmission part. As a result, the light leaks out from the light-emission part to the outside.

Title: Low temperature vessel
Inventor: KAWAGUCHI TAKEO
IPC: F17C13/00
Filed: 1989-02-10
Abstract: PURPOSE:To prevent the irregular change of the temperature of a carrying refrigerant in a way that a gas phase refrigerant and a refrigerant carrying pipe are thermally shielded by a method wherein a shield pipe with which the surroundings of a refrigerant carrying pipe is covered and which is provided at its tip with an opening part opened in the solution of low temperature liquid phase refrigerant is mounted in a low temperature vessel. CONSTITUTION:A shield pipe is mounted in a manner that the inner wall of a shield pipe 23 keeps a space 24 between the inner wall and the surroundings of an insertion part 16 of a refrigerant carrying pipe. A tip 28 of the shield pipe 23 is extended to a level 13 of a low temperature liquid phase refrigerant 12. Since the shield pipe 23 prevents the insertion part 16 of the refrigerant carrying pipe from being exposed directly on unevenness in temperature even when unevenness in temperature occurs due to injection of pressurized gas 21 to the interior of a low temperature vessel 11, the irregular temperature change of a carrying refrigerant 22 can be prevented from production.

Abstract: PURPOSE:To prevent burnt refuse generated at the time of laser treatment from scattering widely in a tubular cavity by mounting on the peripheral surface of a catheter, a filter allowing blood corpuscles in blood flowing in the cavity to pass through and preventing permeation of foreign matter larger than these blood corpuscles. CONSTITUTION:A laser guide 6 is inserted into a catheter 1 inserted into a tubular cabity 2 (for instance, blood vessel) of a human body, and laser beam, emitted from this laser guide 6, is irradiated to a treated location in the cavity 2. A filter 8, which permeates corpuscles in blood flowing in the cavity 2 and prevents permeation of foreign matter larger than these corpuscles, is mounted on the peripheral surface of the catheter q. As a result, flow of the corpuscles in the cavity 2 can be prevented from deteriorating while preventing burning refuse, generated at the time of laser treatment, from scattering widely in the cavity 2.

IPC: B29C48/30
Filed: 1992-01-22
Abstract: PURPOSE:To miniaturize and simplify a molding apparatus and make the formation of resin flow patterns figurate and carry out check of resin flow in the cavity with a high accuracy by disposing magnets at a specified place in the cavity and injecting molten resin being dispersion-admixed with magnetic powders to be attracted by the magnetic force of the magnet into the cavity in order to be molded thereafter. CONSTITUTION:Into the cavity 3 disposed with magnets 9, when molten resin 11 being equally dispersion-admixed with magnetic power 10 is injected from a gate 4, the magnetic powders 10 in the molten resin 11 are attracted and collected together through the attractive operation of the nearest magnet 9, whereby resin flow patterns 12 by gathered magnetic powders appear clearly in the course of passing through the magnets 9. The flow patterns 12 can approximately be made into the formation of stripe patterns that are continue from the position of the magnet 9 to the proximity of end part of the cavity 3. In this way, the resin flow around an aperture 6 can be achieved readily correctly and thereby the gate 4 can be set at a desired position. In order to perform a designing effect for giving a molding appearance alteration, it is also effective at the time of making formative resin flow patterns 12 appear therein.

Abstract: PURPOSE:To separate slurry particles of small grain diameters by intermittently injecting liquid from the peripheral side of swirling flow toward the radial direction of the swirling flow to the slurry, under movement along the swirling flow and along the axial direction of the swirling flow. CONSTITUTION:A separating chamber 2 is communicated on one side with a slurry injection port 5 of a small-diameter part 4 provided on one end side of a main cylinder 1 and communicated on the other one side with a recovering part 4 of a funnel-shaped part 6.
