Patent number: 10325726Abstract: A multilayer ceramic capacitor includes a laminated body and first and second external electrodes respectively on both end surfaces of the laminated body. When regions where first internal electrodes or second internal electrodes are not present are regarded as side margin portions in a cross section of the laminated body as viewed from the laminating direction, the side margin portions include multiple side margin layers, and the content of Si in the side margin layer closest to the internal electrode is lower than that in the side margin layer other than the side margin layer closest to the internal electrode.Type: GrantFiled: April 24, 2018Date of Patent: June 18, 2019Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Hideaki Tanaka, Daiki Fukunaga, Koji Moriyama

Patent number: 9673458Abstract: A fuel cell includes a membrane electrode assembly, a separator, a fluid channel, a fluid manifold, a plurality of protruding elastic members, and a plurality of sealing members. A fluid is to flow in a stacking direction through the fluid manifold. A connection channel is provided between the plurality of protruding elastic members to connect the fluid channel and the fluid manifold. The plurality of sealing members are provided adjacent to the plurality of protruding elastic members in the stacking direction and extend in a direction to cross a flow direction in which the fluid flows along the connection channel. Each of the plurality of protruding elastic members has overlapping regions that overlap the plurality of sealing members as seen from the stacking direction. The overlapping regions are separated from each other in the flow direction.Type: GrantFiled: February 27, 2014Date of Patent: June 6, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Takeshi Ushio, Syuji Sato, Masaru Oda, Yuji Asano, Koji Moriyama
