Patent number: 11183810Abstract: In a light source module A, a lens shapes emitted light 1a of a semiconductor laser. A plate on which the lens is disposed has a through hole through which the emitted light of the semiconductor laser passes and an adjustment surface that is used for adjusting the position of the lens with respect to the through hole in a direction perpendicular to the optical axis L of the semiconductor laser. An end surface 5b of the lens that is opposite to an optical light-emitting surface of the lens is fixed to the adjustment surface with an adhesive AD. A stepped portion that is recessed in the direction of the optical axis L is formed in a bonding portion in which the end surface of the lens and the adjustment surface are bonded together.Type: GrantFiled: December 12, 2019Date of Patent: November 23, 2021Assignee: SHARP KABUSHIKI KAISHAInventors: Toshio Kagawa, Noriaki Fujii

Publication number: 20200185877Abstract: In an optical module (first module (1)), a plurality of semiconductor laser elements (a first semiconductor laser element (21) through a third semiconductor laser element (23)) that output light of wavelengths which are different from each other from light emitting points are mounted on a base member (10). The base member (10) has a reference surface (11) serving as a reference in a height direction (Z) and a mounting surface (a first mounting surface (12a) and a second mounting surface (12b)) on which the semiconductor laser elements are mounted. At least some of the plurality of semiconductor laser elements are different from each other in a height (a first light emission height (TL1) through a third light emission height (TL3)) from a surface in contact with the mounting surface to the light emitting points, and are substantially equal in a height (reference height (HL)) from the reference surface to the light emitting points.Type: ApplicationFiled: January 31, 2017Publication date: June 11, 2020Inventors: YOSHINOBU KAWAGUCHI, SHINJI OSAKI, TAKATOSHI MORITA, SHOGO YANASE, TOSHIO KAGAWA, TERUYUKI OOMATSU, KAZUAKI KANEKO, SHIGETOSHI ITO

Patent number: 5687094Abstract: A design verification apparatus for verifying the suitability of a design to the objectives of a design for an industrial product is disclosed. New design data specification is input. Old design data closest to the new design data is fetched from a design example database and is revised according to the new design specifications. Specification items and tolerance ranges for the specification items are generated based on the input specifications. Verification items based on the old design data and tolerance ranges for the verification items are fetched from a knowledge database. Verify values for the specification items and for the verification items are calculated. The verify values obtained according to the specification items are compared with the tolerance ranges for the specification items, and the verify values obtained according to the verification items are compared with the tolerance ranges for the verification items.Type: GrantFiled: July 6, 1995Date of Patent: November 11, 1997Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Toshio Kagawa, Masaaki Yamane
