摘要： A cam shaft driving device for an engine which is adapted to operably associate a cam gear located on a cam shaft of an upper portion of an engine body with a driving gear on a crank shaft of a lower portion of the engine body, with this association being effected through the intermediary of a cam idling gear. In this device, first and second wall portions, mutually displaced along the axis of crank shaft rotation of the engine and projecting outwardly and laterally from both sides of the engine body, provide a receiving space. This receiving space is provided between adjacent cylinders in the engine body and is larger in laterally extending width than a diameter of the cylinders, with this width extending laterally of the cylinders and transversely of the axis of rotation of the crank shaft. A single gear holder is located in said receiving space, with this gear holder being mounted on at least one of the wall portions. The cam idling gear is rotatably supported and received on a side surface of the single gear holder. A shock absorbing, swingable boss/bearing arrangement may be provided for supporting the idling gear so as to control back lash phenomena.

摘要： A wavelength conversion module according to the present invention includes an external resonator, a semiconductor laser module and a wavelength conversion device for converting a wavelength of light output from the semiconductor laser module into a shorter wavelength. This wavelength conversion device includes at least one of a nonlinear crystal for generating SFG (Sum-frequency Generation) light and a nonlinear crystal for generating SHG (Second Harmonic Generation) light. Each of the SFG generating element and the SHG generating element of the wavelength conversion device may have a periodically-poled ridge-waveguide structure or a periodically-poled proton-exchanged-waveguide structure.
