Patent number: 11476224Abstract: In a wiring member, an element connection portion, a plate connection portion, and an upper surface portion are at height positions different from one another. The element connection portion has a through hole, and the plate connection portion has a through hole and a chamfer. The upper surface portion which is not connected to another portion, has projections asymmetrically disposed on both side surfaces thereof. Owing to these features, the type, the orientation, and the front and the back of the wiring member can be easily distinguished. Accordingly, it is possible to prevent incorrect assembling of the wiring member in a semiconductor module.Type: GrantFiled: May 8, 2018Date of Patent: October 18, 2022Assignee: Mitsubishi Electric CorporationInventors: Kensuke Takeuchi, Takashi Nagao

Patent number: 11402024Abstract: A gate valve includes a valve plate and a valve rod that are detachably connected along a rod axis by screwing a connecting screw in a screw hole formed at an end of a valve rod through a screw insertion hole formed in the valve plate. The valve plate includes a contact portion that is in contact with the connecting screw. When the connecting screw is loosened to detach the valve plate from the valve rod, the valve plate is displaced along the rod axis together with the connecting screw via the contact portion to move to a valve-plate detaching position at which the connecting screw comes completely out of the screw hole of the valve rod. Accordingly, the valve plate can be detached from the valve rod easily and reliably even if the valve rod is tightly inserted in the valve plate mounting hole.Type: GrantFiled: June 8, 2021Date of Patent: August 2, 2022Assignee: SMC CORPORATIONInventors: Hiroshi Ogawa, Takashi Nagao

Patent number: 11302597Abstract: A semiconductor device is provided with a heat dissipating face side skirt portion, which is a frame-form projection, on a heat dissipating face of a lead frame. Because of this, creepage distance increases with a small increase in an amount of resin, and insulating properties improve. Also, the heat dissipating face side skirt portion is molded via two transfer molding steps, wettability of the second molding resin with respect to a first molding resin and the lead frame increases, and adhesion improves. Furthermore, an end face of an inner lead is exposed in an element sealing portion on a mounting face side, and covered with a second thin molded portion molded using the second molding resin, whereby heat generated in a semiconductor element can efficiently be caused to escape from faces of both a first thin molded portion and the second thin molded portion, because of which heat dissipation improves.Type: GrantFiled: September 21, 2017Date of Patent: April 12, 2022Assignee: Mitsubishi Electric CorporationInventors: Takanobu Kajihara, Katsuhiko Omae, Takashi Nagao, Masayuki Funakoshi, Norio Emi, Atsuki Fujita, Yuki Okabe
