    摘要: A vortex prevention apparatus is combined with a pump, and prevents an air entrained vortex or a submerged vortex from being produced when water in the pump pit is pumped up by a pump. A suction member is disposed in an open water channel and has a suction port. An auxiliary flow-path forming structure is disposed substantially concentrically around the suction member with a gap defined between the auxiliary flow-path forming structure and an outer circumferential surface of the suction member.

    摘要: An electrode plate suitable for use in an electro-optical device, such as a liquid crystal device, is formed by successively disposing on a substrate a first layer of a transparent conductor film, a second layer of molybdenum or a molybdenum alloy, a third layer of aluminum or an aluminum alloy, and a fourth layer of molybdenum or a molybdenum alloy. The laminate electrode structure is patterned by a photolithographic process, followed by removal of the photoresist with a peeling liquid, during which the fourth molybdenum layer functions as a protective film for the third al layer against the peeling liquid to prevent the formation of electrode defects.

    摘要: A liquid crystal device includes a pair of substrates with a orientation controlling film being provided on at least one of the substrates through a base layer, and a ferroelectric smectic liquid crystal which is disposed between the substrates. The orientation controlling film has a uniaxial orientation processing axis. The ferroelectric smectic liquid crystal generates two different stable orientation states at high and low temperatures regions within the temperature range achieving the ferroelectric smectic phase. The ferroelectric smectic liquid crystal is in one of the two stable orientation states which is generated at the low temperature region when the liquid crystal in the other stable orientation state generated at the high temperature region cools. Where d is the thickness of the orientation controlling film and S is the average surface roughness of the base layer, d and S have the relation expressed by0.ltoreq.S/d
