摘要： An object is to form a positive electrode active material having small and highly uniform particles by a simple process. A template is formed by forming holes in the template by a nanoimprinting method, and the template is filled with a gel-like LiFePO4 material, whereby small-sized LiFePO4 particles are formed and are used as the positive electrode active material of a secondary battery. The particle size can be reduced to less than 50 nm. Further, when the LiFePO4 particles are sintered, the template may be burned down. By making the particle size of the positive electrode active material smaller than the conventional one, a positive electrode that lithium is injected into and extracted from easily can be manufactured.

摘要： In a starter (1) for an internal combustion engine including a planetary gear type reduction gear unit (2) and a housing (17) for accommodating at least the reduction gear unit (2), a recess (51) is formed at a lower part (17a) of the housing (17) in an installed state of the starter (1) in a manner that the recess (51) is formed in an inner periphery of the housing (17) so as to define a drain passage (51) extending substantially axially, and a part (52) of an outer periphery of a first annular member (12), which constitutes a part of the reduction gear unit (2), protrudes into the recess (51). Thus, the protruding part (52) of the outer periphery of the first annular member (12) forms a labyrinth structure in the drain passage (51) defined by the recess (51) formed in the inner periphery of the housing (17), to thereby effectively prevent water from entering the housing (17) through the drain passage (51) without substantially impeding the passage of water from the housing (17) to the outside. This protruding part (52) is integrally formed in the first annular member (12), and therefore no additional component parts are required to make the labyrinth structure.

摘要： A starter system for an internal combustion engine having a casing provided with a mounting circumferential surface adapted to be substantially closely fitted into an associated mounting bore provided in the engine or a transmission housing associated therewith, and a mounting flange extending radially from the casing and provided with a mounting end surface perpendicular to a longitudinal line of the output shaft of the starter system and spaced from the mounting circumferential surface along the longitudinal line. Because of the presence of the distance between the mounting end surface of the mounting flange and the mounting circumferential surface of the starter casing closely fitted into the mounting bore, the reaction force acting on the pinion is prevented from being amplified and transmitted to the mounting surfaces by means of an undesirable lever action.

摘要： In a coaxial engine starter comprising a pinion (6) connected to the output shaft (4) which is driven by an electric motor (3), via a helical spline (19), a switch unit (7) for selectively closing a power supply line to the electric motor, and a solenoid device (9) consisting of an annular armature and an annular energization coil surrounding the output shaft to axially drive the pinion and a moveable contact of the switch unit in the axial direction, the switch is adapted to be closed before the pinion is actuated by the solenoid device. Therefore, the output requirement for the solenoid device can be reduced as opposed to the conventional starter in which the pinion is actuated strictly by the solenoid device, and the size of the engine starter can be reduced.

摘要： In an engine starter including a solenoid device for actuating a switch for the electric motor and to drive the pinion into mesh with the ring gear of an internal combustion engine, the solenoid device includes an armature outer member which moves in the direction to push out the pinion against the spring force of a first return spring in the energized state of the solenoid device, and an armature inner member which is resiliently urged by a second return spring, and is telescopically disposed with respect to the armature outer member with a coil spring interposed coaxially between them. An annular spring retainer is press fitted into the inner bore of the armature outer member to receive a corresponding coil end of the coil spring. The spring retainer is stamp formed from non-magnetic material so as to have cylindrical portion which is fitted into the bore of the armature inner member, a flange portion which is bent perpendicularly from the cylindrical portion in the manner of an inwardly directed flange in its installed state, and a guide piece portion which is bent perpendicularly with respect to the axial direction from the free end of the flange portion. The forming of the armature outer member is thereby simplified, and the guide piece portion supports the coil spring with a centering action. More importantly, the spring retainer which may be made of non-magnetic material can prevent any significant leakage of magnetic flux from the spring retainer.
