    • A bobbin and a magnetic transmitting/receiving stator are positioned by fitting two positioning projections provided for a bobbin flange into two positioning holes formed in a stator flange. The positioning hole has a circular shape and the positioning projection has a flat oval shape which matches a diameter part of the circular shape so that a resin-passing gap is formed between the shapes. Since the resin-passing gap plays the role equivalent to the role of a resin passing hole, the total number of positioning holes and the resin passing holes can be reduced, and magnetic flux passing through the stator flange can be prevented from decreasing. Since a post-forming resin flows through the resin-passing gap in the positioning part, the flow of the post-forming resin can be made uniform in the whole periphery, and occurrence of poor molding can be restricted.
    • 通过将形成于筒管法兰的两个定位突起装配到形成在定子凸缘中的两个定位孔中来定位线轴和磁性传递/接收定子。 定位孔具有圆形形状,并且定位突起具有与圆形直径部分匹配的扁平椭圆形状,使得在形状之间形成树脂通过间隙。 由于树脂通过间隙起到与树脂通孔的作用相当的作用,因此可以减少定位孔和树脂通孔的总数,并且可以防止通过定子凸缘的磁通量减少。 由于后成型树脂流过定位部分中的树脂通过间隙,所以后整形树脂的流动可以在整个周边上均匀,并且可以限制发生差的成型。

    • A solenoid spool valve includes a spool valve, a spring, and an electromagnetic actuator. The spool valve has a generally cylindrical sleeve provided with a fluid input port and a fluid output port and a spool supported in the sleeve for axial displacement to switch between said input and output ports. The spring abuts a first working face of said spool to energize said spool in a first axial direction. The electromagnetic actuator provides an axial drive force to a second working face of said spool in a second axial direction that is substantially opposite to said first axial direction. The first and second working faces are disposed axially inside of both axial end portions of a bearing, respectively, for slidably supporting said spool in said sleeve.

    • A bottomed cylindrical member is disposed inner side of a stator core and a coil. The cylindrical member is made of non-magnetic material such as a stainless steel. The cylindrical member has a small diameter portion at the bottom side and a large diameter portion continuously made with the small diameter portion at the side of an attracting portion and has a larger inner diameter than that of the small diameter portion. The small diameter portion is slidablly in contact with a slider core, and reciprocatably supports the slider core. Since a radius difference between the small diameter portion and the large diameter portion is equal to or larger than 30 μm, a clearance larger than sliding clearance is formed between an inner circumferential surface of the large diameter portion and an outer circumferential surface of the sliding core. Thus, an electromagnetic driving apparatus and an electromagnetic valve, which smoothly reciprocate the sliding core, are provided.
    • 一个有底的圆柱形部件设置在定子铁心和一个线圈的内侧。 圆柱形构件由诸如不锈钢的非磁性材料制成。 圆柱形部件在底侧具有小直径部分,并且在吸引部分侧与小直径部分连续地形成大直径部分,并且具有比小直径部分更大的内径。 小直径部分滑动地与滑块芯接触,并且可往复运动地支撑滑块芯。 由于小径部与大径部之间的半径差大于30μm,所以在大直径部的内周面与滑动芯的外周面之间形成大于滑动间隙的间隙 。 因此,提供了使滑动芯片平滑地往复运动的电磁驱动装置和电磁阀。

    • An objective of the present invention is, in refining a metal or a semiconductor melt, without impairing refining efficiency, to alleviate wear and tear commensurate with unevenness in a crucible caused by instability in melt flow, and to allow safe operation over long periods of time such that leakages from the crucible do not occur. Provided is a metal or semiconductor melt refining method, in which, by using an AC resistance heating heater as a crucible heating method, the melt is heat retained and mixed by a rotating magnetic field which is generated by the resistance heating heater. The metal or semiconductor melt refinement method and a vacuum refinement device which is optimal for the refinement method are characterized in that, in order that a fluid instability does not occur in the boundary between the melt and the bottom face of the crucible when the melt is rotated by the rotating magnetic field, with a kinematic viscosity coefficient of the melt designated ν (m2/sec), the radius of the fluid surface of the melt designated R (m), and the rotational angular velocity of the melt designated Ω (rad/sec), the operation is carried out such that the value of a Reynolds number (Re) which is defined as Re=R×(Ω/ν)̂(1/2) does not exceed 600.
