Brushless motor (1) which is an electric motor, is provided with a stator unit (3) inserted in and engaged with case (2). A part of the coating material (21) for coating the coil (17) of the stator unit (3) enters the receiving part (13) formed in the bottom part (2B) of the case (2); and the bottom part (2B) of the case (2) and the coil (17) are linked by this coating material (21). While coating, the coating material (21) is dripped from the opening side of the case (2) with the stator unit (3) in the inserted condition in the case (2).

A rack-assist type electric power steering device (10) uses a motor (1) as a drive source. The stator (11) of the motor (1) includes a stator core (13) having ring-like yoke portion (16) and teeth (17) projecting from the yoke portion (16) in the inner direction. In the stator core (13), the ratio (Wy:Wt) between the width (Wy) of the yoke portion (16) in the radial direction and the width (Wt) of the teeth (17) in the circumferential direction is 1:1.4 to 1.8. By setting the yoke portion (16) and the teeth (17) of the stator core (13) to this value, the stator core (13) can be set such that torque slack is difficult to occur within a restricted space

The ingrown nail correcting device is to correct ingrown toenails by using a plate-like member made from a shape memorizing alloy or shape memorizing resin material. A plate-like member (10) formed from a shape memorizing alloy or shape memorizing resin material is preliminarily made to memorize a specified shape at a specified temperature. The plate-like member (10) is bent in accordance with the bent portions of an ingrown nail (12) of a big toe (11) at room temperature, and adhesively bonded to the surface of the ingrown nail (12) with the aid of an adhesive agent. The atmospheric temperature is elevated to the specified temperature, whereby the ingrown nail (12) is corrected by the restoring force of the plate-like member (10) directed toward the arrows..quadrature.

A waterproof electric motor structure in which a yoke 5 is covered with a bottomed cylindrical waterproof cover 12. An open end edge portion 12a of the waterproof cover 12 is internally engaged with a recessed groove portion 10b of a pump bracket 10 by being abutted thereagainst and sealed by a seal member 13. Through holes 5d, 12c are defined in the yoke 5 and the waterproof cover 12, respectively, and a locking cylinder 12d is formed in the cover side through hole 12c. A coupler 14 assembled to pass through both the through holes 5d, 12c is supported by the locking cylinder 12d in a removal prevention state. Further sealing is made by interposing a seal member 16 between a cover side stepped portion 12f and a coupler side stepped portion 14d.

A motor 11 is used for an electric power steering apparatus or the like. A power supply section 31 from which a wire harness 33 electrically connected to a brush 23 is led along the axial direction of an output shaft 12 is provided on an end surface 25a of a bracket 25 of the motor 11 in one end side of the bracket. The power supply section 31 has a power supply terminal 44 provided in a brush holder unit 24 and extending in the axial direction, a connection hole 37 opened through the end surface 25a and containing the power supply terminal 44, a terminal unit 32 attached to the connection hole 37 and having a joint terminal 34, and an O-ring inserted between the terminal unit 32 and the end surface 25a. The end surface 25a is provided with a counter lock portion 29, and the motor 11 is positioned and fixed to a gearbox. As a result, wiring can be arranged in the axial direction without bending the wire harness.

An electric motor structure is shown in which a yoke supporting an armature shaft is fixedly secured to a bracket with set bolts passing through the yoke in the axial direction and in which the distances between a pair of brushes and a pair of internal terminals connected thereto are substantially equal to each other. In a base unit, set bolt through holes for allowing the penetration of a pair of set bolts and a pair of brush holders are disposed on diameter lines perpendicular to each other, and further, a pair of internal terminal plates are disposed to straddle the outer circumference of one set bolt. The inserting tip portion of a coupler unit equipped with external terminal plates electrically connected to the internal terminal plates is branched into two sections. When the coupler unit is connected to the internal terminal plates the set bolt is positioned between the branched sections of the coupler unit.

A tool for treatment of an ingrown toenail includes a tubular member having a length of about 1–2 cm and being tapered such that a diameter at a root is about 2 mm and a diameter at a tip is about 2 mm. Holes are distributed over the tubular member. The tubular member has a slit with saw-tooth edges and has a C-shaped cross section. A side edge of a nail plate is inserted into the slit and the saw-tooth edges secure the tubular member to the nail plate. A super elastic wire is inserted into one or more holes to fix the wire to the tubular member. An elastic force of the super elastic wire applied to the side edge of the nail plate is distributed substantially over a whole length of the side edge to correct the side edge into a flat shape.

A method of winding an armature coil, wherein out of slots (S1-S12) of an armature core (12), slots (S5, S8) away from eccentric portions (13a, 14a) of first and second balancers (13, 14) which are disposed at opposite sides of the armature core (12) are designated as the slots in winding starting positions, respectively, and coils (16) are wound from the slots (S5, S8) into slots (S2, S11), so that the coils (16) are not brought into contact with the eccentric portions (13a, 14a).
摘要:
A monocrystal growing apparatus having a separator provided in a chamber-defining housing for separating the part of a polycrystal rod supported by a vertical shaft, to produce a melt between the polycrystal rod and a seed crystal, from the doping gas atmosphere used during the melting operation. The separator is open to the chamber near the melt and a device passed an inert gas into the separator to prevent the doping gas from invading the chamber. The apparatus produces a monocrystal rod of a constant resistivity along its rod.
