  • Publication number: 20240101813
    Abstract: A molding material is a molding material including linear alkyl-based polyester, highly polar polyester, cellulose fibers, and a flame retardant, in which a total content of the linear alkyl-based polyester and the highly polar polyester is less than or equal to a content of the cellulose fibers, the flame retardant has a phosphazene skeleton or a phosphoric acid ester skeleton in a molecular structure, and a content of the flame retardant is 1% by mass or greater and 10% by mass or less with respect to the total content of the linear alkyl-based polyester, the highly polar polyester, and the cellulose fibers.

  • Patent number: 6384561
    Abstract: Master and slave servo control circuits 2a and 2b are configured with servo controllers 3a, 3b, servo amplifiers 4a, 4b, servo motors 5a, 5b, feedback detectors 6a, 6b and error detectors 7a, 7b, and the servo motors 5a, 5b are mechanically interlocked and connected to a load. At a location upstream from the servo amplifier 4b, a torque command value selector 21 is provided; when the error detector 7a does not detect an error in the servo control circuit 2a, the selector switches so that the servo amplifier 4a and the servo amplifier 4b both receive a torque command value from the servo controller 3a, and when the error detecter 7a detects an error in the servo control circuit 2a, the selector switches so that the servo amplifier 4b receives a torque command value from the servo controller 3b.

  • Patent number: 5590152
    Abstract: Two upper electrodes 16 and 17 are horizontally spaced apart from each other with a predetermined distance and vertically extend through a furnace roof 3 of a furnace shell 2. Upper conductors 20 and 21 are connected to the upper electrodes 16 and 17 and extend in a direction away from the upper electrodes 17 and 16, respectively. Two lower conductors 22 and 23 are connected to a lower electrode 1 and extend in directions along which the upper conductors 20 and 21, respectively. Power source circuits 24 and 25 are arranged between extension ends of the upper and lower conductors 20 and 22 and 21 and 23, respectively. Arcs 12a and 12b generated between the upper electrodes 16 and 17 and the lower electrode 1 are directed to a center of the furnace shell 2.

  • Patent number: 4096126
    Abstract: A thermoplastic copolyester elastomer which comprises dicarboxylic acid component mainly composed of terephthalic and phthalic acids, wherein the molar ratio of terephthalic acid to phthalic acid is from about 80/20 to 35/65, and diol component mainly composed of 1,4-butanediol. The elastomer has excellent thermal stability and weatherability and can be improved in the elastomeric properties by orientation of polymer molecule before crystallization.
