摘要： The stroke apparatus contemplated herein comprises a plurality of annular races each having an inner annular surface of an arcuately bulging cross-section and rotatably accommodated in a support. These annular races are rotatably journaled in a housing in an alternately offset or staggering fashion. A rotary shaft extends through these annular races, and one of the race supports has a pivotal shaft placed at the center of, or at a shifted position from, the corresponding other races and the upper and lower race supports have their pivotal shafts placed in positions shifted to the opposite sides of the rotary shaft. The bulging cross-sections of each of the annular races is forced in contact with the rotary shaft. A guide stem is provided in parallel with the rotary shaft and engaging said housing for sliding movement therealong.

摘要： A light-emitting semiconductor device is provided having a light-emitting semiconductor element emitting light in two directions. The light-emitting element is disposed in a housing so that one light-emitting face of the semiconductor element adjacent a heat sink, and a light guide is arranged to confront the other light-emitting face of the semiconductor element and to guide light from said other light-emitting face to the outside of the housing. In this device, the end face of the light guide confronting said other light-emitting face of the semiconductor element includes a face substantially inclined to the optical axis of light emitted from the semiconductor element.
