摘要:
A fuel cell made up of a pile of unit cells, each consisting of a pair of cell element and separator packed in a cell frame, in which there are formed a fuel feed path and oxide product evacuation path in the piling direction. The cell frame is provided between its inner edge offsets and the outer edges of the cell element and separator with inner packings, and further provided near its outer edge on one side with an outer packing. The sealing structure perfectly prevents a fuel leak, and yet allows compactness and easy assembling process.

A fuel cell made up of a pile of unit cells, each consisting of a pair of cell element (27) and separator (29) packed in a cell frame (12), in which there are formed a fuel feed path (13, 14) and oxide product evacuation path (20) in the piling direction. The cell frame is provided between its inner edge offsets and the outer edges of the cell element and separator with inner packings (21a, 21 b), and further provided near its outer edge on one side with an outer packing (23). The sealing structure perfectly prevents a fuel leak, and yet allows compactness and easy assembling process.

A protrusion (8) is formed downstream of the throat of an insulating nozzle (1) of a gas-insulated circuit breaker of puffer type. Quenching gas, after collision with the protrusion (8), is blown against an arc (12) generated between a fixed arcing contact (2) and a moving arcing contact (6) in the opening process of the gas-insulated circuit breaker. As a result, a pressure drop at or near the forward end (Q) of the fixed arcing contact (2) can be prevented thereby to improve the insulation strength in the opening process.
摘要:
A SF 6 gas insulating electric apparatus usable as a circuit breaker, etc., containing a SF 6 gas insulator and a resin insulator, both of which insulators are present in an atmosphere to be exposed to arcs, characterized by making at least the surface portion to be exposed to arcs of the resin insulator from a polymer containing nitrogen atoms or a polyolefin resin. and if necessary together with an inorganic filler powder, is excellent in both surface and inner arc resistance and can maintain breaking performance for a long period of time.

摘要:
A light (30) beam including a random polarization and radiated from a light source, such as laser oscillator (6) is separated into P wave polarization light beam and S wave polarization light beam by a beam splitter 33. After modulated by image information representative of characters to be printed, both the P and S wave polarization beams are merged and the resultant light beam is projected on the surface of a workpiece for marking a pattern.
