Publication number: 20130311148Abstract: A performance value DB stores multiple states of parts comprising a system, and the consumed power of parts in those states. In addition, a condition DB stores conditions when the states of the parts change. A calculator generates state sequences in which the states are arrayed in the order of change in accordance with conditions stored in the condition DB, when information indicating the states of the parts is not communicated. The calculator computes the percentage of the time the parts are in each state per unit time for each state comprising this state sequence. Furthermore, the calculator finds the products of the computed ratios and the consumed power stored in the performance value DB for each state comprising the state sequence, and estimates the sum of the products found as the consumed power of the part.Type: ApplicationFiled: September 14, 2012Publication date: November 21, 2013Applicant: Mitsubishi Electric CorporationInventors: Masashi MORI, Hiroaki Sakai, Yoshinari Sugegaya

Publication number: 20130149079Abstract: A sample transfer mechanism of the present invention is characterized broadly by a sample gripping method in which a downward part of a sample vessel is gripped and a cover that achieves an effect as a guide such that gripping arms that grip the sample vessel avoid contact with other objects and bypass surrounding objects, particularly, the sample vessels in approaching and retracting motions. To enhance the effect as the guide and to ensure that the sample vessels can be mounted with a high degree of integration, the shape of the cover and disposition of the sample transfer mechanism are characterized in a number of manners. Thus, a sample transfer mechanism that can perform a transfer process safely with high throughput even under conditions in which a variety of types of sample vessels is mixed together and the sample vessels are mounted with a high degree of integration is provided.Type: ApplicationFiled: August 31, 2011Publication date: June 13, 2013Applicant: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Akihiro Ohiso, Yoshiteru Hirama, Tatsuya Fukugaki, Tetsuya Isobe, Hiroaki Sakai
