Patent number: 8938596Abstract: In a storage apparatus, when a received backup instruction is a backup start instruction, a control unit performs a backup process from a position indicated by an available area start pointer. When the received backup instruction is a backup end instruction, the control unit releases an allocated backup area. In addition, the control unit determines whether the released backup area is adjacent to a position indicated by an available area end pointer. If determining that the released backup are is adjacent to the position indicated by the available area end pointer, the control unit moves the available area end pointer indicating the end of an available area to the end of the released backup area.Type: GrantFiled: September 11, 2012Date of Patent: January 20, 2015Assignee: Fujitsu LimitedInventors: Hajime Endoh, Hideaki Takahashi, Takaomi Furoku, Hideyuki Tanaka, Hajime Kondo

Patent number: 8725442Abstract: The present invention provides a novel measurement method for system parameters of a 5-port junction used in a VNA (Vector Network Analyzer). A VNA is a device for measuring amplitude ratios and phase differences (S-parameters: scattering matrix elements) between incident waves and reflected waves of a DUT (Device Under Test), or between input waves and transmitted waves. What has been newly discovered is that for 5 ports, S-parameters can be expressed by a linear coupling using H and power difference ratios ({P(S)/P(0)}?1). It is possible to easily calculate parameter H using a minimum of three already known standards, and amount of calculation can be reduced compared to conventionally.Type: GrantFiled: February 2, 2010Date of Patent: May 13, 2014Assignees: The University of Electro-Communications, Campus Creat Co., Ltd.Inventors: Hajime Kondo, Toshiyuki Yakabe, Hatsuo Yabe
