Title: Superconducting coil, bobbin and manufacture thereof
Inventor: OGAWA SEIJI
IPC: H05H13/04
Filed: 1992-05-19
Abstract: PURPOSE:To obtain a precise winding of a flat type superconducting wire by covering the surface of helical groove in a bobbin body with a resin layer having corner part machined in right angle and laminating a coil of a flat type superconducting wire thereon thereby obtaining a bobbin having an accurate groove shape. CONSTITUTION:A winding groove 2 of bobbin body 1 is subjected, at the outer periphery thereof, to resin injection taping, as required, and then normal temperature curing epoxy resin is injected therein. Resin is injected unilaterally so that air is not trapped therein. After curing the resin, groove part 3 is machined so that an insulation film 4 provides desired film thickness and groove dimensions. A flat type superconducting wire 5 is then wound precisely on the insulation layer 4 thus obtaining a superconducting coil. The insulation layer 4 is provided with precise perpendicular corners by machining the injected resin. This method produces a highly reliable superconducting coil in which quenching is suppressed.

Title: Production of fusion type optical fiber coupler and fusion type optical fiber coupler as well as optical fiber gyro
Inventor: SHIMIZU RYOTARO
IPC: G02B6/28
Filed: 1992-05-19
Abstract: PURPOSE:To facilitate the control to stop heating regardless of a variation in the min. value of a monitor output. CONSTITUTION:The wavelength of a light source to be used for the production of the coupler is set at the wavelength different from the wavelength at the time of actually using the coupler so that fusing and stretching are controlled to be stopped at the prescribed point at which the monitor light output rises again after attaining the min. value. The branching ratio comes to a point C1 or C2 in the case of the coupler produced by setting the branching ratio of the wavelength to be used at 50%. The branching ratio decreases gradually from 100% when the change in the branching ratio at the time of production of the coupler is taken into consideration and, therefore, the stop control at the prescribed point where the branching ratio increases again after attaining the min. value can be eventually executed if the wavelength at which the branching ratio falls below 50% is selected as the wavelength of the light source to be used at the time of production. The selection of the suitable wavelength of 45 to 10% branching ratio is preferable for the easy decision of the reincrease of the light output. Then, the wavelength around the point C3 is merely necessitated to be selected when the use wavelength falls onto the point C1 and the wavelength around the point C4 to be selected when the wavelength falls onto the point C2.
