  • Publication number: 20060155522
    Abstract: An equivalent circuit for a coil incorporated in a circuit simulator is a model of an equivalent circuit for a coil included in a circuit simulator for analysis of an electrical device including a coil forming a magnetic circuit. The equivalent circuit of a coil included in an electric motor or other electrical device is preferably comprised of a resistance component (R), induced voltage component (?d?/dt), and inductance component (L). The equivalent circuit of the inductance component is provided with a current source, a voltage extractor for extracting the voltage across the terminals of this current source, a current generator for determining the value of the current of the current source based on the value of the voltage output by this voltage extractor, and a current-carrying path connected in parallel to the current source and carrying a regenerative current at the time of off operation.

  • Patent number: 7065291
    Abstract: In a video recording/playback apparatus, when recording a series of packets transmitted over an IEEE 1394 bus, a relative value is taken between a requested time of arrival written in a header portion and a cycle time at the time of reception, and then the requested time of arrival is replaced with the relative value. When playing back the series of packets, the relative value is added to a cycle time at the time of transmission, and the relative value is replaced by the obtained value which will be used as a requested time of arrival for playback.

  • Publication number: 20050107253
    Abstract: Provided is an adsorbent for phosphoric acid which can be produced with ease, exhibits high adsorbability of phosphoric acid and is free from any problems in use thereof. The adsorbent for phosphoric acid which includes a water-insoluble reaction product formed by mixing an iron ion and a natural polysaccharide having a carboxylic functional group or a sulfuric acid functional group such as alginate, pectin and carrageenan in a solution, or a dried product thereof. The additional incorporation of a hydrophilic polymer such as agar into the adsorbent prevents the reduction in adsorbability of phosphoric acid in the case where a trivalent iron ion is used to produce the dried product of a water-insoluble reaction product.
