Title: Optical switch
Inventor: URAIRI KENICHIROU
IPC: G02B26/08
Filed: 1989-11-09
Abstract: PURPOSE:To relax adjustment accuracy and to realize multichannel constitution by swtiching the position of output light by rotating a prism which has a couple of mutually parallel reflecting surfaces slantingly to an input optical axis around nearby the input optical axis. CONSTITUTION:Diverged light emitted from the tip of an input-side optical fiber 10 is converted by a lens 11 into incident parallel luminous flux 14, which is made incident on the prism 12, wherein the light is reflected by its 1st reflecting surface 12a and 2nd reflecting surface 12b. The projection parallel luminous flux 18 projected from the prism 12 is made incident on and converged by a lens 17a to enter an output-side optical fiber 16a. Then a rotary shaft 15 is rotated by a specific angle so as to switch outputs of output-side optical fibers 16a - 16d. At this time, the optical path moves to the position of the projection luminous flux 18 according to the angle of rotation of the rotary shaft 15. Consequently, the position accuracy of the prism and the position accuracy of the rotary shaft to the input optical axis are relaxed greatly and the multichannel constitution is easily realized.

Abstract: PURPOSE:To use the cordless terminal equipment automatically for an extension base station by retrieving automatically other base station and retrieving similarly the extension base station when speech lines of an existing base station are all busy. CONSTITUTION:When the user makes dialing from a cordless terminal equipment A, after the end of the dial entry by the user, a cordless terminal equipment processing sets entered dial information in a dial form and makes a selection request of a speech line to a base station whose location is registered such as a station C. Then the terminal processing awaits a reply with respect to the request and when reception information is busy for the selection of a speech line, the selection request of a similar speech line is made to other base station in a bypass table generated among existing base stations of the same location registration area in advance for bypass control. As a result, when the the speech line is not available, the similar request of the speech line is made to other base station in the bypass cable. When the line is busy further, the base station other than those not listed in the bypass cable is automatically retrieved.

Title: Disk winding of induction apparatus
Inventor: NAKATATE MASUMI
IPC: H01F27/12
Filed: 1990-11-01
Abstract: PURPOSE:To ensure a flow rate sufficient for cooling each horizontal cooling path, and to prevent a local temperature rise by arranging a disk winding and an insulating cylinder so that the width of a vertical cooling path is kept within a specified range. CONSTITUTION:The width Sv of an internal vertical cooler 8 and an external vertical cooler 9 as the thickness of an internal choke plug 10 and an external choke plug 11 is set so that 20mm<=Sv<=60mm holds. When Sv is less than 20mm, a refrigerant stays in the lower section of one cooling section. The flow rate of the refrigerant is kept approximately constant when Sv exceeds 60mm, and cooling efficiency is not subject to an effect approximately even when Sv is increased more than that. Accordingly, the distribution of the flow rate of the refrigerant in a horizontal path can be equalized by setting Sv in 20-60mm, thus increasing the flow rate of the refrigerant, then preventing a local temperature rise.

Abstract: PURPOSE: To suppress under-cutting and to improve radioactive resistance by forming an oxidizable side wall at the side face part of an insulation body area adjacent to a semiconductor mesa, oxidizing it later and forming an oxide side wall. CONSTITUTION: A side wall insulation body 50 is formed on the side face of the semiconductor mesa 40 with an upper insulation body 48 and the layer 56 of an oxidizable material is formed at the side face part of the insulation body area.

Title: Stripping jig for insulating film of magnet wire
Inventor: KUWABARA HIROFUMI
IPC: H01F41/10
Filed: 1985-12-26
Abstract: PURPOSE:To obtain a stripping operation rapidly without irregularity with less damage of a core wire by revolving a rotary magnet rotating around its own axis around the outer periphery of a magnet wire to effectively contact it with the insulating film on the wire. CONSTITUTION:When a main shaft roller 4 coupled directly with a motor 5 rotates clockwise, a roller 3 contacted with counter surface of the roller 4 rotates in an opposite direction. The roller 3 is coupled through a magnet holding shaft 2 directly with a rotary magnet 1, which rotates in the same direction as the roller 3. The roller 3 is also contacted with the inner surface of an outer cylinder 6 to tend to transmit a rotary force to the cylinder 6. However, since a bearing 7 and a bearing guide 10 for supporting the roller 3 are fixed to a rotary unit holding sleeve 13 and the sleeve 13 is mounted through a needle bearing 14 on the cylinder 6, the entire rotary unit rotates, when the cylinder 6 is fixed, in an opposite direction by a reaction. As a result, the magnet 1 revolves around the magnet wire 17 at a predetermined interval while rotating around its own axis.

Inventor: OI KENICHI
IPC: G01R31/28
Filed: 1994-11-02
Abstract: PURPOSE: To insert and remove a connector by using mechanical forces without increasing the size of a constant temperature bath. CONSTITUTION: By horizontally and vertically moving an extruding bar 10 in the same plane within the extent of the width of a burn-in board to be attached to a prescribed position by means of air cylinders 11 and 12 and hooking the burn-in board on a hooking surface 10a, the edge of the burn-in board is inserted into an edge connector 2 on a constant temperature oven side and, at the same time, the edge is removed by pushing the front shoulder section of the burn-in board with an extruding surface 10b. Therefore, the labor required for removing the connectors of burn-in boards set in multiple stages can be reduced, because the connectors can be surely removed by using mechanical forces from a simple mechanism which makes linear movement only, and burning-in of numerous ICs can be performed efficiently.  Since the size of the constant temperature bath is not increased, the cost does not increase.

Title: Soundproof sheet for piping
Inventor: UWANO SHOJI
IPC: F16L55/02
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To heighten soundproofing effect and reduce the possibility of separation even in case of being applied to the curved surface of piping by laminating a plastic film with sagging on the surface of vibration damping sheet. SOLUTION: In drainage structure, drain from a toilet bowl 8 generates noise mainly caused by water flow sound based on drop energy in a first vertical drain pipe 1a, noise mainly caused by impulsive vibration in a first elbow pipe 2a, low noise in following lateral drain pipes 4a, 4b, a T-pipe 3, and the like, and maximum noise in an underground drainage system 7 via a second elbow pipe 2b and a second vertical drain pipe 1b. In soundproof sheets 5, 6, plastic films are therefore laminated with sagging on damping sheets. Stress caused by thermal expansion and thermal contraction of a viscoelastic composition generated in association with ambient temperature change, and separating stress caused by resilience of the plastic film can be both absorbed.
