    摘要: A mica-reinforced propylene resin composition having a volatile matter at 105.degree. C of 0.12% or less is obtained by heating and melting a mixture containing (A) a crystalline polypropylene, (B) mica treated with an organosilane compound, (C) a bismaleimide compound, and (D) an organic peroxide. It has excellent stiffness, heat resistance and dimensional stability, does not corrode a mold, and does not exhale an irritating odor during molding.

    摘要: A semiconductor device includes a semiconductor substrate having a first surface being an element formation surface, and a second surface opposite to the first surface; a through-hole formed to penetrate the semiconductor substrate from the first surface to the second surface; an insulating film formed on an inner wall of the through-hole; a barrier film formed on the inner wall of the through-hole with the insulating film interposed therebetween; and a conductive portion formed to fill the through-hole provided with the insulating film and the barrier film. A gettering site is formed in a portion of the semiconductor substrate around the through-hole at least near a side of the first surface.

    摘要: The object of the present invention is to provide a rotary electric machine that provides bobbins with good assembling efficiency and allows no dislocation of the stator. A motor 2 comprises a case 4, a stator 6 secured inside the case 4, a rotor 10 formed into one piece with a rotating shaft 8. The stator 6 comprises stator yokes 32 and the stator yokes are secured in a radial manner in the case 4. Furthermore, resin 58 is filled in between the stator 6 and the case 4 with a space for the rotor being left. The stator yokes 32 comprise a salient pole 34, a bobbin 36 for holding the salient pole 34, and a magnetic wire 38 wound around the bobbin 36. A collar 39b of the bobbin 36 is formed so as to contact each other with notches 3 formed on two, upper and lower edge portions. Accordingly, combining two bobbins 36, 36 allows through-holes 5 penetrating the collar 39b thereof. This allows the stator to be firmly assembled, provides good assembling workability, and allows no dislocation owing to resin flowing when the resin is injected.

    摘要: The object of the present invention is to provide a rotary electric machine which has high assembly accuracy, high heat dissipating efficiency, and excellent durability at the bearing portion. A motor comprises a case, a stator secured within the case, and a rotor formed into one piece with a rotary shaft. The case is provided, on both end faces, with flanges, and one of the flanges is provided with a ball bearing. A stator is radially secured within the case, resin is filled in between the stator and the case with a space of the rotor being left, and a bearing housing and a boss are formed on one side. An open portion is formed in between ribs of the bearing housing, and inserting the bearing into the bearing housing causes a part of the bearing to be exposed through the open portion to fixedly contact with the flange. This allows supporting the bearing securely, and allows frictional heat generated, and the like, to dissipate to the outside via the flange. Furthermore, this allows mounting bearings with high accuracy, and reducing noise accompanying mechanical and electromagnetic vibrations.

    摘要: An inner rotor type motor has a plurality of stator magnetic poles projecting inwardly from a stator yoke surrounding the outer periphery of a shaft, of which a plurality of stator magnetic poles, some, at least the same number as the number of the phases of the driving voltage, are each provided with a driving coil and a decelerating coil wound around the same and form long stator magnetic poles (26), while the remaining stator magnetic poles are each made shorter than the long stator magnetic poles, not provided with a winding, and form short stator magnetic poles. Further, the motor has a rotor rotating centering around the shaft and having rotor magnets made up of permanent magnets disposed in a confronting relationship with salient poles of the stator magnetic poles.
