Title: Optical fiber type optical multiplexer and its production
Inventor: OKAWARA TADAYOSHI
IPC: G02B6/28
Filed: 1993-01-19
Abstract: PURPOSE:To provide the optical fiber type optical multiplexer for optically synthesizing light signals of the same wavelength at low loss and the production of the same. CONSTITUTION:This optical fiber type optical multiplexer is constituted by disposing one piece of >=3 pieces of single mode optical fibers 11 to 13 for the same wavelength at a center and the rest in symmetrical positions to constitute an optical fiber arranging body 14 and subjecting a part thereof to fusion stretching to form a fused part 15. The optical fiber which is previously enlarged larger than the other optical fibers in a part of the cores 11a to 13a thereof by a heat treatment is used as the central optical fiber at this time, by which the light signals propagating in the other optical fibers is synthesized at the low loss with the light signal propagating in the cores of the central optical fiber. This process for production consists in producing such optical multiplexer.

Title: Thin film transistor
Inventor: NOMURA KOJI
IPC: G02F1/1333
Filed: 1985-01-18
Abstract: PURPOSE:To keep destruction only within a restricted portion even if insulation breakdown would be produced at a defect portion in an insulator layer, by dividing a source electrode and drain electrode at least into two regions at sections connected with a semiconductor layer respectively. CONSTITUTION:In order to remove defects such as pin-holes or cracks in a gate insulator film of a first thin film transistor (TFT) T1, between a switching signal bus 34 and information signal bus 28, that is, between a gate electrode 1 and source electrode 3, a large current is caused to flow instantaneously to produce insulation breakdown forcibly. At this time, since the source electrode 3 is divided, the breakdown is stopped by the break of the electrode, so that another electrode portions are prevented from being broken down. Moreover, when a high electric field necessary for emitting light is applied through a second TFT T2 into an EL layer 27, even if insulation breakdown would be produced at a defect portion in the gate insulator film between the gate electrode 6 and source electrode 8, due to the same reason only a restricted portion is broken down. Accordingly, the performance of the TFT presents no problems.
