Abstract: To suppress the magnetizing inrush current occurring when supplying power of three phases of the transformer are performed simultaneously using three single-phase circuit breakers or a non-phase segregated operation-type circuit breaker, without providing a circuit breaker with a resistor or other equipment. A magnetizing inrush current suppression method for transformer suppresses a magnetizing inrush current occurring at the start of energizing of a three-phase transformer 300, when a three-phase power supply 100 is input to a terminal of each phase by means of a three-phase circuit breaker 200.

Abstract: The MPU for switching control arithmetic operation 210 in the switching control arithmetic operation unit 200 performs arithmetic operations to determine a predetermined delay time (synchronous delay count value D) for each circuit breaker 1100. The synchronous delay count value is sent to each switching command control unit 400 of the corresponding circuit breaker. The hardware counter 20 of the switching command output control unit 450, for the switching command signal received from the superordinate device 2000, counts the synchronous delay count value D, which is the delay time. When the semiconductor switch of the switching command output unit 10 turns ON after counting completes, the switching command signal (circuit breaker drive current) after the synchronous switching control is output to the circuit breaker drive coil 1110 of the circuit breaker 1100.

Abstract: Push-pull signal is created on the basis of reflected-light detection signals output from four divided light receiving elements that receive a reflection of a recording laser light beam off an optical disk. The push-pull signal is sent to a gain variation circuit. The push-pull signal is normalized by setting the gain of the gain variation circuit to a low level in response to a mark forming section of a recording signal, but to a high level in response to a blank forming section of the recording signal. Wobble detection and pre-pit detection are performed on the basis of the normalized push-pull signal.

Abstract: A semiconductor device includes a patterned conductive layer on which an initial dielectric film is deposited by a non-etching deposition process. A second dielectric film is then deposited on the initial dielectric film by high-density plasma chemical vapor deposition (HDP CVD). The HDP CVD process etches the second dielectric film as it is being deposited, thereby smoothing the surface of the second dielectric film. The initial dielectric film insulates the patterned conductive layer from the plasma used in the HDP CVD process, so that plasma charge is not conducted to underlying oxide films, such as gate oxide films, and does not cause oxide damage.

The boundary area is formed as either a high-reflection area that presents a higher reflection light level than the divided recording areas or a low-reflection area that presents a lower reflection light level than the divided recording areas.

Abstract: A separator for a low-temperature fuel cell comprises a stainless steel substrate S having a surface to which carbonaceous particles such as graphite particles GP or carbon black aggregates CA adhere with dotted distribution. The carbonaceous particles are preferably bonded through a diffusion layer DL to the surface of the substrate S. The carbonaceous particle-dispersed layer may be a plating layer in which graphite particles GP or carbon black aggregates CA are dispersed or formed by thermal decomposition of organic components in a carbonaceous particle-dispersed paint applied to the surface of the substrate S. Since carbonaceous particles free from oxide films adhere to the surface of the acid-resistant stainless steel substrate S, contact resistance of the separator is sufficiently low. Consequently, a power generator having a plurality of fuel cells laminated together exhibits high power-generating efficiency with less heat loss caused by a Joule heat.
