  • Patent number: 11416438
    Abstract: A circuit device includes a first physical layer circuit to which a first bus is connected, a second physical layer circuit to which a second bus is connected, and a processing circuit that performs transfer processing in which a packet received from the first bus via the first physical layer circuit is transmitted to the second bus via the second physical layer circuit. The processing circuit includes a SYNC generation circuit that generates an m-bit SYNC, and when the packet is received from the first bus, the processing circuit outputs the m-bit SYNC to the second physical layer circuit.
    Type: Grant

  • Patent number: 6832736
    Abstract: In a collecting method and a collecting apparatus for collecting foaming gas generated from foaming heat insulator material, as well as in a processing process and apparatus of disposals, disposals 1 including the foaming heat insulator material 5 are charged into a first and a second crushing machines 3 and 17 for separating the foaming gas contained in the foaming heat insulator material 5 thereof, and the separated foaming gas is collected by a collector 29, wherein measurement is made on the concentration of flammable gas separated, so as to control the charging of the disposals 1 and the foaming heat insulator material 5 into the first and second crushing machines 3 and 17, depending upon that concentration measured, thereby collecting the foaming gas with high efficiency, while controlling the concentration of the flammable gas, appropriately and with ease, and an charge amount thereof to be charged, appropriately, depending upon the concentration of that flammable gas contained therein.

  • Patent number: 4419488
    Abstract: High impact polystyrene having excellent properties is produced by a continuous process comprising feeding rubber and styrene continuously to a multistage horizontal dissolving tank to dissolve the rubber completely with stirring by increasing the temperature of each stage stepwise along the liquid flow direction, feeding the rubber solution to a first polymerizer to effect phase inversion of the rubber and preliminary polymerization of styrene; feeding the pre-polymerized solution to one or more horizontal type polymerizers to undergo bulk polymerization while removing the heat generated therein; and feeding the polymerized solution to a monomer separator to remove the remaining monomer.
