Abstract: A projector includes a projector body that enlarges and projects image light and an image reproducing device that reproduces an image relating to the image light. The projector body and the image reproducing device are integrally arranged in a vertical direction such that the projector body is above the image reproducing device. A partition member is formed between the projector body and the image reproducing device, and the projector body is placed on the partition member.

Abstract: A structure for attaching a lamp cover (61) to an upper case (21), when a part (631C) of a fitting (631) is pressed downward by a pin member (P) to release engagement of the lamp cover (61) with the upper case (21). The lamp cover (61) is biased toward outside of the exterior case, so that the lamp cover (61) can be opened with one pressing action of with the pin member (P) and operation thereof can be facilitated.

Abstract: A semiconductor device including a substrate having a low substrate surface formed in the substrate with a first gentle slope from the substrate surface; a single crystalline layer formed on the low substrate surface nearly level with the substrate surface and having a gentle slope facing the first gentle slope; an optical semiconductor element is constructed using the single crystalline layer. An electronic semiconductor element is constructed using the substrate surface. A wiring layer connects electrodes of the optical semiconductor element and the electronic semiconductor element through the first and the second gentle slopes.

Abstract: The smoking composition referring to the reconstituted tobacco or tobacco substitute and composing of natural tobacco material and/or organic or inorganic material(s), which are combustible as raw materials, and of CMC-Na as binder, is heated at 110.degree.-240.degree. C., preferably at 150.degree.-200.degree. C., desirably for 150-5 minutes, so as to reduce the moisture content thereof to 1% and below. The smoking composition thus heating-processed exhibits a markedly superior water-resistance to the smoking composition not heating-processed, while the former exhibits equal physical properties except water-resistance and organoleptic properties to the latter.
