Patent number: 11935674Abstract: An object is to provide a laminated varistor excellent in clamping voltage ratio. Laminated varistor includes at least a pair of internal electrodes provided in varistor layer containing ZnO as a main component. Internal electrode contains Ag as a main component and is made of a metal containing at least one type selected from Pt and Au. The total weight of Pt and Au with respect to the weight of the metal constituting internal electrode is set between 2% and 30% (inclusive). With such a configuration, diffusion of Ag into varistor layer can be prevented, and a laminated varistor excellent in clamping voltage ratio can be obtained.Type: GrantFiled: June 28, 2021Date of Patent: March 19, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Mikinori Amisawa, Masuto Omiya, Kouji Hirate, Yukihito Yamashita, Touichi Makita

Patent number: 10950907Abstract: A battery pack includes a plurality of battery cells, case (housing), circulation path, and blower. The circulation path includes battery paths, inflow side space, outflow side space, and a path along the housing. The battery paths are formed by gaps between adjacent battery cells. The inflow side space distributes fluid to the inlets of the battery paths. The outflow side space gathers fluid from the outlets of the battery paths. The path along the housing is a path that is different from the inflow side space and outflow side space and extends along one or more inner surfaces of the case. The circulation path is formed such that at least one of a flow velocity of the fluid in the inflow side space and a flow velocity of the fluid in the outflow side space is slower than a flow velocity of the fluid in the path along the housing.Type: GrantFiled: August 1, 2016Date of Patent: March 16, 2021Assignee: DENSO CORPORATIONInventors: Hiroyoshi Yamamoto, Yoshimitsu Inoue, Kouji Yamashita
