  • Publication number: 20140009127
    Abstract: Three-phase TSCs are delta-connected to three-phase AC buses. Each TSC includes a reactor, a capacitor, and a thyristor switch that are electrically connected in series. The thyristor switches of the three phases are arranged so that the terminal-to-terminal distance between respective thyristor switches of respective phases are not uniform. The three-phase TSCs are configured so that the TSCs of two of the three phases having a shortest terminal-to-terminal distance therebetween are opposite to each other in terms of connection order in which the thyristor switch and the capacitor are electrically connected along a loop path made up of the delta-connected TSCs.

  • Publication number: 20120292811
    Abstract: The present invention is a method for producing a resin-molded body for a hollow structure having a cavity and an opening connecting the cavity and the outside. The method includes the steps of: creating a hollow core corresponding to the shape of the cavity; creating an outer mold corresponding to the external shape of the hollow structure; setting the core in the outer mold and injecting a fluid of a soft-resin material into the space between the outer mold and the core; demolding a soft-resin-molded body together with the core from the outer mold after the soft-resin-molded body is formed by curing the soft-resin material, applying an external force to the soft-resin-molded body to deform the soft-resin-molded body so as to break the core into fragments; and discharging the fragments of the core through the opening of the soft-resin-molded body to the outside.

  • Patent number: 7755333
    Abstract: 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.

  • Publication number: 20100173331
    Abstract: 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.

The compensation capacitor control device includes a detection voltage output circuit which outputs a bus detection voltage after the clearing of a voltage drop abnormality, corresponding to the AC voltage of a system bus after the voltage drop abnormality that occurred in the AC power system has been cleared, and a compensation capacitor control circuit which controls the connection status of a compensation capacitor with respect to the system bus. The compensation capacitor control circuit controls the connection status of the compensation capacitor with respect to the system bus, on the basis of the voltage level of the bus detection voltage after the clearing of the voltage drop abnormality.

  • Patent number: 7688043
    Abstract: 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.
