Patent number: 7755333Abstract: A SVC control section detects a bus voltage from an instrument transformer, and adjusts reactive power generated by a SVC according to the detected bus voltage. A cooperative control section generates a control command for controlling the interconnection and parallel-off of a phase lead capacitor and a phase lag reactor on the basis of the amount of reactive power generated by the SVC and the bus voltage detected by the instrument transformer and a voltage sensor. A voltage comparator compares the bus voltage with a predetermined threshold voltage set to a voltage lower than a lower limit value of a steady state fluctuation range of the bus voltage and outputs the comparison result to a circuit breaker control section. When the bus voltage is lower than the threshold voltage, the circuit breaker control section locks the control command from the cooperative control section.Type: GrantFiled: May 6, 2008Date of Patent: July 13, 2010Assignee: Mitsubishi Electric CorporationInventors: Satoshi Yasuda, Hitoshi Teramoto, Masatoshi Takeda, Michihiro Tadokoro

Publication number: 20100173331Abstract: It is intended to provide extracellular markers whereby Notch signal transduction can be detected. Polypeptides (N?), which are novel peptides originating in Notch protein and released form cells in the step of the nuclear migration of NICH (Notch intracellular cytoplasmic domain) due to the extracellular digestion and the subsequent protein digestion in the membrane during a series of the Notch protein digestion, are referred to as markers. These peptides (N?) are released from the cells in proportion to the Notch signal depending on presenilin. By detecting these peptides, the Notch signal transduction, cell differentiation, cell tumorigenesis, apoptosis, Alzheimer's disease, etc. can be monitored.Type: ApplicationFiled: December 30, 2009Publication date: July 8, 2010Inventors: MASAYASU OKOCHI, MASATOSHI TAKEDA

Patent number: 7688043Abstract: In a conventional reactive-power compensator using a static reactive-power compensator (SVC), there are many cases in which the SVC is operating in a state in which it generates an amount of reactive power equivalent to a large part of its capacity. When an unforeseen large voltage fluctuation occurs in this state, the SVC can not sufficiently generate the amount of reactive power required to mitigate the voltage fluctuation. In some cases, such a voltage fluctuation can not be brought under control. To address this situation, a reactive-power compensator utilizes a reactive-power control apparatus that includes a comparison voltage generator for generating, for a control target voltage and to mitigate voltage fluctuation, a comparison voltage restricted within predetermined limits and obeying a predetermined time-lag characteristic. A differential voltage generator generates a differential voltage that is the difference between the comparison voltage and the control target voltage.Type: GrantFiled: June 25, 2007Date of Patent: March 30, 2010Assignee: Mitsubishi Electric CorporationInventors: Naohiro Toki, Masatoshi Takeda, Yoshiyuki Kono, Koji Temma
