Abstract: A light emitting device includes a light emitting element that emits light, and a wiring substrate that includes a light reflective reflecting electrode to which the light emitting element is bonded using a bonding material. The reflecting electrode has a reflecting region which reflects light emitted from the light emitting element. An area of a mounting region surrounded by an outer circumference of the reflecting region is greater than an area of the light emitting element by four times or more seen in a direction perpendicular to the wiring substrate.

Abstract: An interference filter is fixed with respect to a base substrate by a fixing member which is disposed on one portion which is on the outer side of a filter region. Accordingly, since the periphery end of the interference filter, other than a portion (end portion) in which the fixing member is disposed, becomes a floated state (free end), it is possible to suppress the warping of the interference filter even when there is the difference in coefficients of thermal expansion with the base substrate. Further, spacer portions which are lower than the height of the fixing member are formed outside the filter region and on the portion separated from the fixing member. At the time of the impact, since the spacer portions come in contact with the base substrate to function as stoppers, it is possible to suppress occurrence of peeling-off or cracks on the fixing member.

Abstract: An electro-optical apparatus including: an electro-optical panel on which a plurality of electro-optical devices are arranged; a focusing lens which focuses light emitted from the electro-optical devices; an optically transparent spacer which is interposed between the electro-optical panel and the focusing lens and contacts the electro-optical panel and the focusing lens; and a frame which has a first facing surface facing a first surface which is a surface of the spacer on the side of the focusing lens, wherein the first surface contacts the first facing surface.

Abstract: An electro-optical device includes a substrate, a plurality of self-emitting elements formed in the substrate, a sealing member attached to the substrate so as to seal the self-emitting elements in cooperation with the substrate, and a circuit that is disposed to overlap the sealing member and that drives or controls the self-emitting elements.

Abstract: A dicing apparatus is provided with a first position for feeding a workpiece before dicing, a movable machining table capable of retaining the workpiece, a second position for mounting the workpiece before dicing on the machining table, a third position for washing the diced workpieces, a fourth position for retaining the washed workpieces, a dicing mechanism provided at a dicing range spaced apart from the second position, for dicing the workpiece, and a transferring mechanism for transferring the workpiece from the first position to the second position, from the second position to the third position, from the third position to fourth position, respectively.

Abstract: In a gear tooth having a tooth surface, the gear contact pattern is inspected by the steps of measuring the tooth surface at regularly positioned measuring points to detect deviations from a standard gear profile at corresponding measuring points and counting the number of such measuring points wherein the deviations are within a predetermined limit. Where the counted number is greater than a predetermined value, the tooth surface is accepted.

Abstract: In a pair of intermeshing gear teeth each having a tooth surface, the gear contact pattern is inspecting by steps of measuring each tooth surface at a regularly positioned measuring points to detect deviations from a standard gear profile at corresponding measuring points, calculating relative distances between the teeth surfaces at the measuring points, and counting the number of combinations of measuring points wherein the relative distances are within a predetermined limit. Where the counted number is greater than a predetermined value, the pair of gears are accepted.
