摘要:
A distributor for an internal combustion engine has a housing, a shaft inserted in the housing, a head mounted on the shaft, a cap attached to the housing so as to cover the rotor head, a signal detector accommodated in the housing, a connector projecting outside the housing, and an ignition coil accommodated in the housing. The housing has a cut-out portion formed in a side wall thereof from an abutment between the cap and the housing and extending toward the bottom of the housing for receiving the connector, and the cap and the connector are tightly engaged with the housing through a gasket. Silicon rubber is charged in the gap between the housing and the ignition coil. A heat release plate may be provided between the housing and the signal detector so that a path formed by the plate and the housing and surrounding a section of the core is electrically cut off, whereby no current flows in the path.

A writing implement provided with a strong clip is simple in construction and is provided with a coil spring restrained from easily falling off. The writing implement (1, 11, 21) includes a tubular body (2), a clip (3), a pillar (7) formed on the outer surface of the tubular body, a connecting structure R connecting the clip and the pillar, a coil spring (4) extended between the inner surface of the clip and the tubular body and capable of loading the clip such that a front end part (3aa) of the inner surface of the clip is pressed elastically against the outer surface of the tubular body, and a projection (5) formed on the outer surface of the tubular body so as to project toward the clip and fitted in the coil spring. Preferably, the clip is provided with a back wall (10) projecting from a back part (3ab) of the inner surface (3a) of the clip and the coil spring is disposed on the front side of the back wall. The projection (5) has a height not smaller than half the length of the coil spring.

An electric power steering drive system provided with a motor with its torque pulsation reduced, and a controller characterized by excellent manufacturability. The stator core of a motor is composed of an annular back core and a plurality of teeth created separately from the back core and secured on the inner periphery of the back core. An 8-pole/9-slot, 10-pole/9-slot or 10-pole/12-slot relationship is found between the number of the magnets of a rotor (number of poles) and the number of slots. The diameter of the stator coil is 1.0 mm or more. A motor controller comprises a power module, a conductor module and a control module. The terminal of the power module and the bus bar of the conductor module are connected by welding, whereas the terminal of the power module and terminal of the control module are connected by soldering.
摘要:
An electronic distributor for an internal combustion engine, having a plurality of switching elements for conducting and breaking currents flowing to a plurality of ignition coils, a first lead frame for separately flowing the currents of the plurality of switching elements to the plurality of ignition coils and a second single lead frame for dropping current levels of currents of at least two switching elements of the plurality of switching elements to a common electric potential, characterized in that a resistance value of the first lead frames has been set to be larger than a resistance value of the second lead frame.

A movement detecting device having a light transmitter 44 and a spaced light receiver 46, with a moving plate 32 containing slit apertures therein being positioned between the transmitter and receiver for interrupting the light path between the transmitter and the receiver in dependence upon the motion of the moving plate. So as to improve the clarity of light detection, stationary apertured plates 56U, 56D are unitarily formed and are positioned on respective sides of the moving plate and adjacent a respective one of the transmitter or receiver. The stationary apertured plates 56U, 56D may be formed from a single sheet of material (FIG. 18), or from two separate sheets connectingly joined by a flanged pin (FIG. 12), or a combination thereof. The unitarily formed stationary apertured plates 56U, 56D may be directly molded into a support housing (38, 60, 62 in FIG. 8) with locating holes 64, 66 for the light transmitter 44 and light receiver 46, or may be formed in a molded sub assembly (FIG. 5) prior to moulding into a support housing (FIGS. 4 and 7).
