Publication number: 20240161950Abstract: A multilayer ceramic component according to the present disclosure includes a sintered body, a plurality of internal electrodes, and a side surface electrode. The side surface electrode includes: a primary electrode layer containing silver as a main component thereof; and a plating layer covering the primary electrode layer at least partially. The primary electrode layer includes a first terminal portion provided for the side surface of the sintered body and a second terminal portion. The second terminal portion extends, in a second direction, from at least one of a pair of end portions of the first terminal portion in a third direction and is provided for at least one of a pair of principal surfaces. An interposed portion is formed by allowing a part of the plating layer to enter a region where a tip of the second terminal portion and the sintered body are separate from each other.Type: ApplicationFiled: March 9, 2022Publication date: May 16, 2024Inventors: Yuto AKIYAMA, Sayaka WATANABE, Yuji YAMAGISHI

Publication number: 20230115279Abstract: A fuel cell system includes a plurality of fuel cells and a control device that controls an operation state of each fuel cell. The control device has a command receiver that acquires an output command showing a total output power which should be generated by the fuel cell system, a first determiner that determines the number of fuel cells which should be operated in the normal operation mode, and an operation state manager that determines the operation state of each fuel cell. Based on the output command, the operation state manager changes the operation state of at least one of the fuel cells which are being operated in the normal operation mode to the standby operation mode, or changes the operation state of at least one of the fuel cells which are being operated in the standby operation mode to the normal operation mode.Type: ApplicationFiled: August 23, 2022Publication date: April 13, 2023Applicant: Toshiba Energy Systems & Solutions CorporationInventor: Sayaka AKIYAMA

Patent number: 11379493Abstract: An apparatus as an aspect of the present invention is a factor analysis apparatus that analyzes a relationship between a target event that is a target of factor analysis and an assumed factor of the target event, and includes a similarity calculator, a first influence calculator, and a second influence calculator. The similarity calculator calculates a degree of similarity between a data item included in provided time-series data and the assumed factor. The first influence calculator calculates a first degree of influence indicating a degree of influence of the data item on the target event on the basis of time-series data of the data item and time-series data of the target event. The second influence calculator calculates a second degree of influence indicating a degree of influence of the assumed factor on the target event on the basis of the degree of similarity and the first degree of influence.Type: GrantFiled: February 20, 2018Date of Patent: July 5, 2022Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Sayaka Akiyama, Kohei Maruchi, Masatake Sakuma
