Abstract: A bearing device includes a rotating shaft; a first bearing including a bearing ring rotating with the rotating shaft and a plurality of rolling bodies which are contacted by the bearing ring; and second bearing in which the rotating shaft is rotatably mounted, the second bearing having a flange member which is brought into contact with the plurality of rolling bodies, is integrally formed in the second bearing and is disposed on the opposite side of the rolling bodies, in an axial direction of the rotating shaft through the bearing ring.

Abstract: An aminopyridine compound represented by the formula: ##STR1## wherein n represents 0 or 1; Z represents .dbd.S, .dbd.NCN or .dbd.CHNO.sub.2 ; R.sub.1 represents --NR.sub.3 R.sub.4, --NHNR.sub.3 R.sub.4, --NHCONHR.sub.3 or --NHSO.sub.2 R.sub.3 ; R.sub.2 represents H, or substituted or unsubstituted alkyl; R.sub.3 and R.sub.4, which may be the same or different, represent H, substituted or unsubstituted alkyl, aryl, substituted or unsubstituted acyl or alkoxycarbonyl group; and R.sub.3 and R.sub.4 may form a heterocyclic ring together with a nitrogen atom to which R.sub.3 and R.sub.4 are bound, through another heteroatom or without it; an optical isomer thereof or art acid salt thereof, which is excellent in pharmacological effect and repressed in side effects as a drug for circulatory diseases.

Abstract: An armature core comprises a core element made of a magnetic material, wherein the core element has an annular portion. A plurality of salient poles are radially formed on the core element. A plurality of rib portions are formed on the salient poles, respectively; coils are wound around the rib portions. An insulating layer is formed on the surface of the core element. The insulating layer being provided with an area where surface of the core element excludes the insulating layer.

Abstract: An armature core wire winding method in which the armature core has salient poles set to be an integral multiple number of three, the salient poles protruded radially from an axial core portion of the armature core, the method comprises the steps of; winding three wires in two stages around three salient poles, respectively, the three salient poles being included in a first block; drawing out three transition wires from the three salient poles of the first block, respectively, in such a manner that each transition wire is drawn out at one surface side of the salient poles; extending the transition wires in such a manner that the transition wires pass over two adjoining the salient poles; winding the transition wires around salient poles of a second block, respectively, each salient pole of the second block corresponding to each salient pole of the first block; and repeating the winding, drawing out, extending and the winding steps until the transition wires completely wind around the salient poles.

Abstract: An aminopyridine compound represented by the formula: ##STR1## wherein n represents 0 or 1; Z represents .dbd.S, .dbd.O, .dbd.NCN or .dbd.CHNO.sub.2 ; R.sub.1 represents --CN, --NR.sub.3 R.sub.4, --CONR.sub.3 R.sub.4, --NHNR.sub.3 R.sub.4, --NHCONHR.sub.3, --NHSO.sub.2 R.sub.3 or --SR.sub.3 ; R.sub.2 represents H, or substituted or unsubstituted alkyl; R.sub.3 and R.sub.4, which may be the same or different, represent H, substituted or unsubstituted alkyl, aryl, substituted or unsubstituted acyl or alkoxycarbonyl group; and R.sub.3 and R.sub.4 may form a heterocyclic ring together with a nitrogen atom to which R.sub.3 and R.sub.4 are bound, through another heteroatom or without it; or an acid salt thereof, which is excellent in pharmacological effect and repressed in side effects as a drug for circulatory diseases.

Abstract: A holder for holding a magnetic sensitive element by which the magnetic sensitive element may be secured at a desired position so as to obtain favorable output characteristics and to reduce the area which the element occupies. The holder positions the magnetic sensitive element opposite a magnetic drum, within a magnetic encoder, and comprises a movable holder for holding a magnetic sensitive element connected to a flexible signal input/output member, a fixed holder fixed to a circuit board for holding the movable holder, and a guide which is biased against the movable holder to permit movement of the movable holder in a direction perpendicular to the magnetic sensitive surface of the magnetic sensitive element to a desired set position to thereby adjust the gap between the magnetic sensitive element and the magnetic drum.

Abstract: A brushless motor improving the structure for connecting the stator coil to the substrate to facilitate the operation of connection and assembling. The constitution comprises a rotor having a rotor magnet (11), a stator core (2) on which the stator coil (7) is wound to be opposed to the rotor magnet (11), a circuit substrate (4) connected to the stator coil (7), and an insulating core holder (3) which holds a terminal to which the coil will be connected and which mounts the stator core (2), the core holder (3) being placed on said circuit substrate (4) and said terminal being soldered to terminal portions on the circuit substrate (4).
