Patent number: 11966096Abstract: A first lens body and a second lens body are fixed to, using an adhesive layer, a surface of a lens fixing plate determined by intersection of a straight line in an optical axis direction and a straight line in a longitudinal direction, such that the lens fixing plate in which a lens fixing plate opening is formed in a lateral direction overlaps, when viewed in the lateral direction, at least a portion of a junction at which the first lens body and the second lens body are bonded to each other. A first adjustment member is brought into contact with the first lens body via at least one hole into which the first adjustment member is inserted A second adjustment member is brought into contact with the second lens body via at least one hole and into which the second adjustment member is inserted.Type: GrantFiled: April 12, 2019Date of Patent: April 23, 2024Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Toshiyuki Sawabe, Takami Urasaki, Takashi Maekawa

Patent number: 11956933Abstract: No consideration is given to heat transferred from a semiconductor module to a capacitor via a bus bar module. The heat generated by a semiconductor module (1) is transferred to a bus bar module (3) via a DC terminal (1A) of the semiconductor module (1). As illustrated in FIG. 4(B), the heat transferred to the bus bar module 3 is then transferred to the pressing member 5 via the annular conductor 8 and the bolt 5A. Since the pressing member 5 is in close contact with the second cooler 2B, the heat transferred to the pressing member 5 is cooled by the second cooler 2B. On the other hand, the heat transferred to the convex portion 6A of the housing 6 is transferred to the first cooler 2A via the housing 6 and cooled. As a result, in the configuration in which a capacitor (4) is connected to the semiconductor module (1) via the bus bar module (3), the heat transferred from the semiconductor module (1) to the capacitor (4) can be suppressed.Type: GrantFiled: July 31, 2020Date of Patent: April 9, 2024Assignee: Hitachi Astemo, Ltd.Inventors: Takashi Hirao, Takeshi Tokuyama, Noriyuki Maekawa, Akira Matsushita, Toshiya Satoh
