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 optical filter device includes a wavelength tunable interference filter, a lid having a second opening, a base that forms a receiving space together with the lid, a second glass member that covers the second opening and is bonded to the lid through low melting point glass, and a metal layer provided on the lid. The metal layer is provided outside a line that is separated from the outer peripheral edge of the second glass member by a predetermined distance toward a side away from the second opening and is disposed along the outer peripheral edge of the second glass member in plan view when the lid is viewed from a normal direction with respect to the opening surface of the second opening.

Abstract: A optical device storage package includes a storage portion configured to store an optical device, a base portion which constitutes a bottom portion of the storage portion, a side wall portion which is integrally molded with the base portion and which constitutes a side surface portion of the storage portion, and a first lid portion joined to the side wall portion so as to cover the storage portion, constituting a top portion opposing the bottom portion of the storage portion and hermetically sealing the top portion, wherein the first lid portion is formed of a light-transmissive member.

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.
