Patent number: 10079087Abstract: In the dither current power supply control method, in order to prevent occurrence of a difference between the target average current and the detected average current, which is caused when a medium current (I0) between a dither large current (I2) and a dither small current (I1) and a waveform average (Ia) of the dither current are different from each other depending on a response time difference (a?b) between a rise time (b) and a fall time (a) of the dither current, negative feedback control is carried out by using a command medium current corresponding to the target average current corrected by a correction parameter based on experimentally measured data, thereby suppressing occurrence of a transient fluctuation error by the negative feedback control, so that a highly precise and stable load current is acquired.Type: GrantFiled: February 11, 2016Date of Patent: September 18, 2018Assignee: Mitsubishi Electric CorporationInventors: Shuichi Matsumoto, Masato Nakanishi, Shingo Iguchi, Hiroyuki Arita, Tomoaki Ogata

Publication number: 20020157196Abstract: In order to design an infrastructure of an elevated bridge, first a target ductility factor &mgr;d and target natural period Td for the infrastructure are set in connection with an assumed earthquake motion. Subsequently, a yield seismic coefficient for the target ductility factor &mgr;d and target natural period Td is obtained from a yield seismic coefficient spectrum for the assumed earthquake motion as a design seismic coefficient Kh. On the other hand, a target yield rigidity Kd corresponding to the target natural period Td is obtained. Subsequently, the design seismic coefficient Kh is used to obtain a design horizontal load bearing capacity Hd and a displacement corresponding to the design horizontal load bearing capacity Hd is obtained as a design yield displacement &dgr;d from the target yield rigidity Kd. Subsequently, the design horizontal load bearing capacity Hd is distributed into a horizontal force Hf to be borne by the RC rigid frame and a horizontal force Hb to be borne by the damper-brace.Type: ApplicationFiled: May 8, 2002Publication date: October 31, 2002Inventors: Hajime Ouchi, Motoyuki Okano, Hajime Wakui, Nobuyuki Mastsumoto, Masamichi Sogabe, Hiroyuki Arita

Patent number: 5736982Abstract: A plurality of terminals are connected to a server via a communication network and share a predetermined common virtual space. The terminals each send to the server the position coordinates of the viewing point and direction of eyes of its user in the virtual space, and the visual field image viewed from that viewing point is displayed on a display. Based on the position coordinates and direction of eyes of the avatar each of the other terminals received from each of the other terminals via the server, each terminal generates an avatar image in the specified direction and at the specified position and displays it in the visual field. The server is always supplied with the latest position information of the avatar from every terminal and, when the distance between two arbitrary avatars becomes smaller than a threshold value, connects speech channels of the two terminals corresponding to these avatars.Type: GrantFiled: August 1, 1995Date of Patent: April 7, 1998Assignee: Nippon Telegraph and Telephone CorporationInventors: Gen Suzuki, Shohei Sugawara, Hiroya Tanigawa, Machio Moriuchi, Yoshio Nagashima, Yasuhiro Nakajima, Hiroyuki Arita, Yumi Murakami

As the assistant, a water-soluble resin or a water-insoluble resin having a carboxylic acid salt group is used optionally in combination with a surface active agent. The spun product is a fiber bundle in which single filaments having a diameter smaller than 100 .mu.m are gathered in parallel to one another, and this fiber bundle is easily opened.Type: GrantFiled: September 24, 1985Date of Patent: February 28, 1989Assignee: Mitsui Petrochemical Industries, ltd.Inventors: Shiro Homma, Masatoshi Kashiwagi, Hiroyuki Arita

Patent number: 4788907Abstract: An apparatus for loosening and freezing heat processed cereals is disclosed. The cereals are in the form of separate grains when in a raw state and exhibit agglutinating properties after heat processing so as to become affixed to one another. The apparatus mainly includes a cylindrical rotary drum adapted for receiving the cereals previously heat processed and for loosening the cereals so as not to form lumps or blocks while the cereals are frozen, a unit for rotating the drum, a loosening member provided in the inside of the drum for carrying up the cereals and falling down in the drum, and a fluid blowing unit. The drum includes a netted wall having a mesh size to prevent the cereals from passing through the drum. The blowing unit is adapted to blow chilling fluid into the inside of the drum through the netted wall for blowing up and simultaneously freezing the cereals.Type: GrantFiled: August 3, 1987Date of Patent: December 6, 1988Assignee: Nichirei CorporationInventors: Junichi Mizutani, Hiroyuki Arita
