Publication number: 20130266450Abstract: Provided is a centrifugal compressor including a first splitter blade 7 arranged nearer to a suction side Sb of a full blade 5F located upstream in a rotating direction of the compressor, and a second splitter blade 8 provided farther from the suction side Sb of the full blade 5F and being shorter than the first splitter blade 7. Leading edges 7a and 8a on the shroud side of the first splitter blade 7 and the second splitter blade 8 are offset from positions dividing the space between the full blades at equal intervals by the number of splitter blades therebetween toward the suction side Sb of the full blade.Type: ApplicationFiled: December 6, 2011Publication date: October 10, 2013Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Isao Tomita, Toru Hoshi

Publication number: 20090252641Abstract: A steel sheet contains, in terms of percent by mass, C: 0.01 to 0.2%, Si: 2.0% or less, and Mn: 3.0% or less and has a martensite phase as dominant phase and ferrite with a grain size of 20 ?m or less as a second phase. The ferrite is contained in area ratio of 1% to 30% and the amount of solute carbon being 0.01 percent by mass of more. The steel sheet can provide a hot-rolled steel sheet suitable for automobile steel sheet, i.e., has excellent press workability and excellent strain aging property whereby the tensile strength significantly increases by heat treatment at about the same temperature as typical baking process after the press-working. Moreover, hardening of the ferrite phase improves the fatigue strength after the strain aging.Type: ApplicationFiled: March 29, 2006Publication date: October 8, 2009Applicant: JFE Steel Corporation a corporation of JapanInventors: Toru Hoshi, Saiji Matsuoka

Patent number: 7508822Abstract: The usage of communication systems is improved. An IM server 4 manages presence information regarding each of IM clients and usable media and user information such that each of the IM clients can obtain these kinds of information. In order to perform text chatting, the IM server 4 manages a connection between each of the IM clients participating the chat and the IM server 4, merges text from each of the participating IM clients and distributes the result to each of the participating IM clients. In order to perform voice chatting, an AP server 5 manages a connection between each of the IM clients participating the chat and an MD server 6, mixes voice from each of the participating IM clients except for a focused IM client and distributes the result to the focused participating IM clients. This processing is performed for each of the participating IM clients.Type: GrantFiled: May 14, 2007Date of Patent: March 24, 2009Assignee: Hitachi, Ltd.Inventors: Keiko Tanigawa, Kazuma Yumoto, Kenta Shiga, Toru Hoshi
