摘要： A direct-current power supply unit is provided for applying forward bias to a pn junction between an n emitter region and a p base region. A switch is provided between the direct-current power supply unit and a first metal electrode layer or a second metal electrode layer. A switch control circuit is connected to the switch. A gate control circuit is connected to the switch control circuit. Accordingly, ON voltage of an IGBT can be reduced while latch-up is avoided.

摘要： A production unit for twisted cable is disclosed that facilitates the supply and removal of fixed length cables, thereby contributing to improved workability and automation compatibility. A plurality of pairs of relatively rotatable opposed cable clamps are provided with one cable clamp of each pair provided at one end of the fixed length cables and the other of each pair of cable clamps provided at the other end. Each pair of clamps is intermittently moved forward in a direction transverse to the opposed direction in which the cables extend. Each pair of cable clamps sequentially circulate, and the supply and removal operation of fixed length cables to and from the pairs of clamps are conducted respectively at predetermined positions by stations provided in the circulating route, by which it becomes possible to carry out the supply and removal of fixed length cables to continuously repeat the twisting operation.

摘要： In the manufacture of a rare earth sintered magnet of the Nd.sub.2 Fe.sub.14 B system, closed voids are formed in the magnet in a predetermined fraction to minimize shrinkage. Unlike open voids or pores in conventional semi-sintered magnets, the closed voids do not incur magnet corrosion since they do not communicate to the magnet exterior. By minimizing shrinkage during sintering in this way, a ring or plate-shaped thin wall anisotropic magnet can be prepared without machining for shape correction, achieving a cost reduction and a productivity improvement. Since a high density compact has a high deflective strength, it is easy to handle, minimizing cracking and chipping between the compacting and sintering steps.
摘要翻译：在制造Nd2Fe14B系稀土烧结磁体时，以预定的比例在磁体中形成封闭的空隙，以使收缩率最小化。与常规半烧结磁体中的开放空隙或孔不同，封闭的空隙不会引起磁体腐蚀，因为它们不与磁体外部连通。通过以这种方式使烧结期间的收缩最小化，可以在不进行形状校正的机械加工的情况下制备环形或板状的薄壁各向异性磁体，从而实现成本降低和生产率提高。由于高密度压块具有高的偏转强度，因此易于处理，使压实和烧结步骤之间的裂纹和碎裂最小化。

摘要： A melt of Nd-Fe-B alloy is injected in an inert gas atmosphere through a nozzle against a chill roll or a pair of chill rolls rotating relative to the nozzle for contacting the melt with the circumference of the chill roll or rolls, thereby quenching the melt. The chill roll has a low heat conductivity surface layer around a base or has a predetermined surface roughness on its circumference. The contact time of the melt with the chill roll can be increased by blowing an inert gas flow. Further the melt is quenched in an inert gas atmosphere of up to 1 Torr. A wind shield is disposed in proximity to the chill roll circumference for preventing a wind of the ambient gas induced by rotation of the chill roll from reaching a paddle of the melt. With these means, there is obtained a permanent magnet material having a grain diameter with a reduced variation.
摘要翻译： Nd-Fe-B合金的熔体通过喷嘴在惰性气体气氛中通过冷却辊或相对于喷嘴旋转的一对冷却辊注入，用于使熔体与冷却辊或辊的周边接触，从而淬火熔化。冷却辊在基部周围具有低导热性表面层或在其圆周上具有预定的表面粗糙度。可以通过吹入惰性气流来增加熔体与冷却辊的接触时间。此外，熔体在高达1托的惰性气体气氛中淬火。挡风玻璃设置在冷却辊周边附近，用于防止由冷却辊的旋转引起的环境气体的风到达熔体的桨叶。通过这些方法，获得具有减小的变化的粒径的永久磁铁材料。

摘要： An image forming apparatus includes first and second image-forming portions and an intermediate transporting portion. A control unit checks fixing units in the image-forming portions and determines whether or not the fixing unit in the first image-forming portion is a fixing unit for an envelope. If not, the control unit controls a manipulation and display unit to display guidance for urging a user to exchange the first fixing unit. If so, the control unit determines whether or not too fixing unit in the second image-forming portion is a fixing unit for an envelope. If not, the control portion controls a manipulation and display unit to display a guidance for urging a user to exchange the second fixing unit. If both of fixing units in the first and second image-forming portions are fixing units for the envelope, the control unit allows an envelope mode control operation.
