摘要： 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, or from two separate sheets connectingly joined by a flanged pin, or a combination thereof. The unitarily formed stationary apertured plates 56U, 56D may be directly moulded into a support housing with locating holes 64, 66 for the light transmitter 44 and light receiver 46, or may be formed in a moulded sub assembly prior to moulding into a support housing.

摘要： A distributor for an internal combustion engine comprises a housing, a shaft inserted in said housing 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, and having a connector projecting outside the housing, and an ignition coil accommodated in the housing. The housing has a cut-off portion formed in a side wall thereof from an abutment between the cap and the housing toward a bottom of the housing for receiving the connector, and the cap and the connector are tightly engaged with the housing through a gasket. A 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 constructed by the plate and the housing and surrounding a section of the core is electrically cut off, thereby no current flows in the path.
