Patent number: 6839597Abstract: A state-of-device remote monitor system capable of applying a general-purpose line as a transmission line for transmitting detection signals of a state of a device, comprises an on-the-spot area, and a management area. The on-the-spot area includes an electric device, a detector for detecting a device state of the electric device, and a first communication signal converter for converting detection data obtained by the detection of the detector into communication signals, and transmitting the communication signals.Type: GrantFiled: February 15, 2002Date of Patent: January 4, 2005Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Takayuki Hattori, Ikuo Ikeda, Riichiro Tsutsumi

Publication number: 20030220704Abstract: A remote service offering system is provided, which includes a plant having a plant server and a plant controller, an end user terminal, and a center having a center database and a center server, the plant, the end user terminal and the center being connected to one another through a wide-area network. When the center server receives a request for display of accumulated information from the end user terminal, it obtains accumulated information held by the plant server and provides the accumulated information to the end user terminal. When the center server receives a request for display of real-time information from the end user terminal, it obtains real-time information collected by the plant controller and provides the real-time information to the end user terminal.Type: ApplicationFiled: May 15, 2003Publication date: November 27, 2003Applicant: MITSUBISHI DENKI KABUSHIKI KAISHAInventors: Masahiko Nanbu, Ikuo Ikeda, Tomohiro Mizukami, Michio Tonosaki, Mitsuo Katagiri, Tadao Mizuno, Takaaki Maekawa

Patent number: 6496391Abstract: A power supply unit for use in a measuring instrument at a plant. An output from a current transformer mounted on a power supply line is controlled so that the range of a primary current producing a stable output is increased. The invention includes a current transformer mounted on a cable for providing power to an electric motor, and a power supply unit. The power supply unit includes a rectifier circuit, a short circuit, a reverse current inhibit element, a condenser, a voltage watching circuit, and a constant voltage element. The voltage watching circuit outputs a command signal when the voltage of the condenser exceeds a first level and connects the short circuit 32.Type: GrantFiled: January 15, 2002Date of Patent: December 17, 2002Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Ikuo Ikeda, Takayuki Hattori

Patent number: 5436269Abstract: A drug for hepatic diseases, particularly an ameliorant for hepatic functions and a drug for hepatitis, containing docosahexaenoic acid or a derivative thereof (DHA) as an active ingredient. The DHA as the active drug ingredient, though also taking part in the metabolism of cholesterol formed in vivo and exuding into the plasma, mainly metabolizes that cholesterol specifically which is accumulated in hepatic microsomes as a result of hypometabolism or dysbolism to thereby bring about the recovery of flexibility of a microsome lipid membrane, thus enhancing the enzymatic activity, and to significantly reduce a triglyceride, thus being prospective as an ameliorant for hepatic functions in treating fatty liver, hepatic cirrhosis, etc. The invention also provides a drug for hepatitis, which can inhibit the induction of hepatitis which is one of the factor causative of chronic hepatitis, hepatocirrhosis, hepatocellular carcinoma, hepatic insufficiency, etc.Type: GrantFiled: November 8, 1993Date of Patent: July 25, 1995Assignee: Sagami Chemical Research CenterInventors: Kazunaga Yazawa, Tomohito Hamasaki, Hirofumi Taki, Kiyosi Kondo, Mitihiro Sugano, Ikuo Ikeda

Patent number: 4969817Abstract: An artificial tooth has a basal plane in which an areal ratio of a labial or buccal subplane to a lingual subplane is in a range of 10:1 to 1:10, and an angle that both subplanes make with a dental axis, i.e., an angle of retention, assumes a concave shape and is in a range equal to or larger than 45.degree. to less than 180.degree.. A retaining hole can be provided in the basal plane of the artificial tooth so as to further improve its performance.Type: GrantFiled: September 30, 1988Date of Patent: November 13, 1990Assignee: G-C Toshi Kogyo CorporationInventors: Kenji Hiranuma, Hiroshi Mori, Akira Hasegawa, Ikuo Ikeda
