Publication number: 20190219639Abstract: An electricity storage device, an electricity storage system and a power supply system capable of setting a full charge capacity corresponding to an actual full charge capacity are developed. The electricity storage device includes a battery part and a control part for controlling charge and discharge of the battery part. The battery part is capable of discharging from a full charge capacity to a preset set capacity. The control part is capable of executing a full charge capacity correction mode, which executes a remaining capacity calculation operation and a consumed capacity calculation operation. The full charge capacity is a sum of a remaining capacity corresponding to a first voltage of the battery part in a state of having discharged to the set capacity and a consumed capacity consumed from the full charge capacity to the set capacity.Type: ApplicationFiled: June 27, 2017Publication date: July 18, 2019Applicant: KANEKA CORPORATIONInventor: Masaru KAWABE

Publication number: 20060048576Abstract: A first object is to provide a method for evaluating large-sized inclusions in a bearing steel. The method enables quantitative evaluation of large-sized inclusions even if the steel has a high degree of cleanliness. Further, a second object is to provide an appropriate bearing steel evaluated by the method for evaluating large-sized inclusions. Further, a third object is to provide a rolling bearing capable of eliminating short life products and cracked products and providing longer lifetime for entire bearings. In order to achieve the first object, a round bar formed of a bearing steel to be evaluated and an ultrasonic probe are placed in an ultrasonic transmission medium, and the size and number of large-sized inclusions that are present in the flaw detection volume are measured to estimate the existence probability of large-sized inclusions in the bearing steel to be evaluated.Type: ApplicationFiled: January 17, 2003Publication date: March 9, 2006Inventors: Akihiro Kiuchi, Yutaka Ishii, Youichi Matsumoto, Masaru Kawabe, Hiroshi Narai, Naoko Yokoyama
