    摘要: A semiconductor light emitting element, a laser or a light emitting diode which is deposited on a first area of a semiconductor substrate, which also carries a microlens for focusing or diverging an output beam of the light emitting element on a second area of the substrate. Both the light emitting element and the microlens are deposited on a substrate through a photolithoetching process, and an alignment of an optical axis of the light emitting element and an optical axis of the microlens is accomplished in the steps of producing a light emitting semiconductor system. Thus, a semiconductor light emitting system which functions not only to generate light but also to focus or diverge the light, and is small in size and light in weight, can be obtained.

    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.
