Filed: 1990-03-20
Abstract: PURPOSE:To facilitate the inputting and outputting of a light signal and to simplify the constitution and the adjustment of an optical system by forming a one conduction type silicon semiconductor layer and an MIS structure which allows the transmission of light on an insulating film for reflecting light formed on a silicon semiconductor substrate. CONSTITUTION:The light from an optical fiber 8 is made incident on the (p) type silicon semiconductor layer 3 via a gate electrode 6 the gate insulating film 5. This incident light is reflected by the boundary of the semiconductor layer 3 and the insulating film 2 and returns in the route of the gate insulating film 5  the gate electrode 6  the optical fiber 8. The incident light from the optical fiber 8 is reflected by the boundary of the insulating film 2 when the signal from a modulating signal source 9 and the bias voltage from a bias power source 10 are impressed to the gate electrode 6. The light is then modulated according to the modulating signal from a modulating signal source 9 in either of the process in which the light is made incident on the boundary or the process in which the light is reflected and returned at the boundary or both processes in the process in which the incident light returns to the optical fiber 8. Namely, the light signal inputted to the semiconductor device of the silicon system is modulated and can be outputted in the state of the light signal.

Abstract: PURPOSE:To reduce iron loss by leakage flux in a transversal axis by coating and covering the surface of a magnetic metal wire wound around the iron core for an inductor heater, transformer or the like with an inorganic or organic insulating layer or these compound insulating layer. CONSTITUTION:The following surface treatment is applied to a magnetic metal wire such as a mild steel wire or the like wound around the iron core for an electrical machine or the like. Namely, the surface of the mild steel wire is purified to apply aluminium plating and an Alumite insulating layer is produced by oxidation treatment. Or the mild steel wire is coated and covered by applying or baking a macromolecular material such as an organic insulating agent, for example, insulating varnish, plastic coating material or the like or by glass, asbestos, slag wire fiber to compose a magnet metal wire. After that, the metal wire is wound while applying adhesive to a spool and the metal wire is taken out of the spool after hardening. In this way, the conductive path of eddy current generated by leakage flux in a transversal direction becomes narrow and the absolute value of eddy current is reduced. Therefore, iron loss is reduced and an incerase in temperature is also decreased.
