Patent number: 8492005Abstract: In joining a magnesium alloy material 1 (first material) and a steel material (second material), a zinc-plated steel plate 2 plated with zinc (metal C) is used as a steel material, Al (metal D) is added to the magnesium alloy material 1. Next, eutectic melting of Mg and Zn is caused so as to remove a product produced by the eutectic melting with an oxide film 1f and impurities from a joint interface. Moreover, an Al—Mg system intermetallic compound such as Al3Mg2 and an Fe—Al system intermetallic compound such as FeAl3 are produced, whereby regenerated surfaces of both materials 1 and 2 are joined via a compound layer 3 containing those intermetallic compounds.Type: GrantFiled: January 16, 2009Date of Patent: July 23, 2013Assignee: Nissan Motor Co., Ltd.Inventors: Shigeyuki Nakagawa, Kenji Miyamoto, Minoru Kasukawa, Masao Aihara, Sadao Yanagida, Akio Hirose

Patent number: 7689449Abstract: It is determined whether or not a transmitter has issued a request to display a completion state table, whether or not the current date and time have reached the date and time specified by the transmitter, whether or not an opening rate has exceeded a predetermined value, or whether or not a completion rate has exceeded a predetermined value. When any of these conditions is satisfied, a completion state table containing information such as the number of receivers who have opened the message, the opening rate, the number of receivers who have completed their jobs associated with the message, the completion rate, etc. is forcibly displayed on a terminal device.Type: GrantFiled: January 19, 2000Date of Patent: March 30, 2010Assignee: Fujitsu LimitedInventors: Toshiki Mori, Minoru Kuriki, Yasuyuki Jinbo, Kiyoto Naganuma, Masao Aihara
