摘要： Xenon light emitted from a xenon light source heads for a wavelength-selecting mirror through a taper coupler and an air mass filter. The wavelength-selecting mirror reflects a short wavelength component of the xenon light and emits the short wavelength component to a taper member. Halogen light emitted from a halogen light source heads for a wavelength-selecting mirror through a taper coupler and a reflecting mirror. The wavelength-selecting mirror transmits a long wavelength component of the halogen light and emits the long wavelength component to the taper member. The taper member has width gradually decreasing from an entrance plane for light to an exit plane for the light. The light emitted from the taper member is changed so that a radiation directivity of a component originating from the xenon light becomes similar to a radiation directivity of a component originating from the halogen light. This makes it possible to provide a solar simulator performing irradiation of artificial sunlight having uniform illumination distribution onto an irradiation-target surface.

摘要： The degradation of directivity performance due to stray light with poor directivity entering and propagating through tapered light guiding members can be prevented, and thus the decrease in the degree of spectrum correspondence with sunlight can be prevented. A light shielding member 41 is placed in between adjacent tapered light guiding members 4. Specifically, the light shielding member 41 is attached to or coiled around the surface of a circumference wall of the tapered light guiding member 4, other than one end surface and the other end surface for allowing light to enter and exit. Further, the light shielding member 41 is placed so that stray light will not enter the tapered light guiding member 4 from the circumferential wall thereof, other than the one end surface and the other end surface.

摘要： An internal combustion engine is provided with a crankcase partitioned into an upper section and a lower section. A fastening bolt is provided for fastening the upper and lower crankcase sections together in the vicinity of a crankshaft. A bolt hole is formed in the crankcase, and the fastening bolt is inserted and tightened in the bolt hole. An opening is formed at an end of the bolt hole within the upper crankcase, the end of the bolt hole is made to communicate with this opening, and the end of the fastening bolt protrudes into the opening when the engine is assembled, to lighten the crankcase, and in order to avoid concentrating stress in the bolt hole near the end of the bolt.
