摘要： A valve train for an internal combustion engine includes a camshaft, a valve-operating cam for operating an engine valve, and a link mechanism for swinging the valve-operating cam. The valve train also includes a holder member operable to turn around the camshaft, and a drive mechanism operable to turn the holder member for varying positions of the link mechanism. The drive mechanism includes a ball screw provided perpendicularly to the camshaft, a slider threadably engaged with the ball screw, an arm member swingably attached to the slider, and a connecting bolt having one end secured to an arm-connecting portion of the arm member, and the other end secured to the holder member. In such movable valve train for an internal combustion engine, the holder member and the drive mechanism are connected to each other with a small and lightweight configuration, requiring a minimal number of parts.

摘要： In a rotation angle sensor attaching structure for detecting rotation of a rotational angle detection object shaft through a reduction gear, an outer race of a bearing is force fitted in and secured to a central portion of the reduction gear, and an inner race of the bearing is secured to a supporting wall by a supporting bolt. A sensor-connecting element of a rotation angle sensor, which extends across a head portion of the supporting bolt, is secured integrally to an outer side face of the reduction gear. Such arrangement achieves a minimal size of the rotation angle sensor attaching structure.

摘要： A valve train of an internal combustion engine having a swing of a link mechanism that is stabilized to stabilize the operating characteristics of an engine valve. A camshaft is provided together with a valve operating cam pivotally supported by the camshaft so as to operatively open and close an engine valve. A link mechanism allows a drive cam rotated integrally with the camshaft to swing the valve operating cam, and a drive mechanism swings the link mechanism, wherein opening and closing of the engine valve are started in a buffer section of the valve operating cam, and opening/closing timing of the engine valve is controlled by the drive mechanism swinging the valve operating cam via the link mechanism, without the provision of a buffer transition section and a buffer constant-speed section encountered at the time of transiting from a base circle to a cam lobe of the drive cam.

摘要： A graphite substrate is processed to have surface unevenness in a range of 1 μm to 8 μm. Thereby, a semiconductor film to be laminated on the graphite substrate has a stable film quality, and thus adhesion of the graphite substrate and the semiconductor layer can be enhanced. When an electron blocking layer is interposed between the graphite substrate and the semiconductor layer, the electron blocking layer is thin and thus the surface unevenness of the graphite substrate is transferred onto the electron blocking layer. Consequently, the electron blocking layer also has surface unevenness approximately in such range. Thus, almost the same effect as a configuration in which the semiconductor layer is directly connected to the graphite substrate can be produced.
