摘要： In an electromagnetic converter comprising a rotor arranged by including a permanent magnet, a yoke disposed in the vicinity of the rotor for flowing magnetic flux and a coil wound around the yoke, at least a portion of the yoke is composed of an amorphous metal magnetic material. The amorphous metal magnetic material is a Co amorphous metal or a Fe amorphous metal. The electromagnetic converter is a small generator, a motor and the like. In an electronic timepiece provided with a generator device, the Co amorphous metal magnetic material is used for a first yoke (stator) and the Fe amorphous metal magnetic material is used for a second yoke (coil core). In an electronically-controlled mechanical watch, the Co amorphous metal magnetic material is used for a yoke. Portable electronic equipment is a timepiece provided with the electromagnetic converter, and so forth

摘要： The invention provides an electromagnetic transducer which can improve conversion efficiency by reducing the weight of a rotor and thinning a rotor shaft to reduce both size and weight. An electromagnetic transducer includes a rotor comprising a plurality of magnets with N and S poles arrayed alternately in the direction of rotation of the rotor, and a back yoke for supporting the plurality of magnets. The back yoke is formed with reduced volume regions corresponding to the center of each magnet as viewed in plan based on distribution of magnetic force lines generated inside the back yoke between the N and S poles of the adjacent magnets. With such a reduction of the back yoke, the weight of the back yoke and hence the overall weight of the rotor can be reduced while the magnetic force lines flowing into the magnet are prevented from being saturated.

摘要： An electronic watch is formed of a case body having a display window, a movement situated in the case body, a light transmitting digital display disposed above the movement in the case body to be observed from an outside through the display window, and a solar cell unit. The solar cell unit is interposed between a part of the light transmitting digital display and the movement, and a reflecting plate is disposed under another part of the light transmitting digital display adjacent to the solar cell unit. Also, a light transmitting material is interposed between the part of the light transmitting digital display and the solar cell unit. Thus, light is supplied to the solar cell unit from the outside through the light transmitting digital display.
