  • Patent number: 9363993
    Abstract: An antibacterial resin composition comprising a thermoplastic resin or a thermosetting resin that contains a metal compound represented by the following formula (1), permitting the metal such as silver having antibacterial power to efficiently elute out and the eluted metal to remain stable as metal ions so that excellent antibacterial power can be exhibited using only a decreased amount of an expensive compound containing silver or the like, wherein M is any one of Ag, Cu, Zn, Co or Ni and X is SO2.

  • Patent number: 8921452
    Abstract: [Problems] To provide a resin composition containing ultrafine silver particles and having excellent antibacterial property as well as excellent deodorizing power against both the nitrogen type smelling components and the sulfur-containing smelling components. [Means for Solution] A resin composition obtained by heating and mixing a resin composition, a silver carboxylate and a carboxylic acid together. A thermoplastic resin, the silver carboxylate and the carboxylic acid are heated and mixed together at a temperature lower than a temperature at which the silver carboxylate starts decomposing but not lower than a melting point of the thermoplastic resin.

  • Publication number: 20130335050
    Abstract: In the related art, there is a problem that the condition of a load is monitored in an indirect manner so that an efficiency enhancing effect is not obtained. A switching regulator control circuit includes an oscillator for generating a carrier signal and a transistor drive circuit for driving a switching transistor and a synchronous rectification transistor based on a PWM signal generated based on the carrier signal. The oscillator switches the frequency of the carrier signal based on the direction of a source-drain voltage of the synchronous rectification transistor.

  • Patent number: 7443926
    Abstract: In an apparatus including a shift register adapted to pass a start signal therethrough in synchronization with a clock signal of a large amplitude level to sequentially generate a plurality of latch signals, a data register adapted to latch sequential data signals of the large amplitude level in synchronization with the latch signals, and a data latch circuit adapted to latch all the sequential data signals latched in the data register in synchronization with a strobe signal, a receiver converts differential clock signals of a small amplitude level into the clock signal of the large amplitude level from a timing of generation of the strobe signal to a timing of completion of latching all the sequential data signals in the data register, and transmits the clock signal of the large amplitude level to the shift register, and also, converts differential data signals of the small amplitude level into the sequential data signals from a timing of generation of the start signal to the timing of completion of latching

  • Patent number: 6552710
    Abstract: A horizontal driver in a LCD driver includes a D/A converter having a PROM decoder block and an NROM decoder block for driving a LCD panel in a dot reversible driving scheme. Each data line receives alternately a gray-scale signal having a positive polarity generated by a PROM decoder and a gray-scale signal having a negative polarity generated by an NROM decoder, and an odd-numbered data line and an even-numbered data line receive gray-scale signals having opposite polarities. The order of the decoders is matched by a switching block with the order of the data lines by switching the display data and the gray-scale signals.
