Patent number: 10744644Abstract: A calibration area has a rectangular area and a peripheral area. The rectangular area includes a center area provided in the center portion and a first corner area, a second corner area, a third corner area, and a fourth corner area that are set at four corners sequentially in the circumferential direction. The center area has a line symmetry with respect to each of the two orthogonal axes passing through the center of the rectangular area. The heights of the areas are different.Type: GrantFiled: December 21, 2017Date of Patent: August 18, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomotaka Hagino, Naoto Kagami, Yoichi Naruse, Kaito Matsubara

Patent number: 10381631Abstract: A sealed-type battery includes an exterior body, a collector terminal, a hollow rivet defining a hollow section, and a reverse plate arranged between the collector terminal and the hollow rivet. The collector terminal includes: a projected section projected; a peripheral edge section provided; and a notch section provided in the peripheral edge section in a manner to surround the projected section and formed in a manner to reduce thickness of the collector terminal. In a projected direction of the projected section, the projected section is thicker than the peripheral edge section. A fitting section, to which the projected section is fitted, is provided in the reverse plate. The sealed-type battery includes a welded section that has a top surface opposing the hollow rivet and that joins the collector terminal and the reverse plate at a position between the projected section and the fitting section.Type: GrantFiled: November 16, 2017Date of Patent: August 13, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Naoto Kagami, Tomohiro Ono, Tomotaka Hagino, Yoichi Naruse, Yuta Nemoto, Toshinori Okura, Kaito Matsubara
