  • Patent number: 8045580
    Abstract: The present invention intends to improve communication efficiency between two communication apparatuses each engaged in the communication by full duplex communication method by using a surplus band of the one to transmission band of the other. A first bandwidth required by a first communication apparatus (A) at data transmission and a second bandwidth required by a second communication apparatus (B) at data transmission are presumed. Next, the first bandwidth presumed as mentioned is compared to a first bandwidth used which the first communication apparatus (A) currently uses and at the same time, the second bandwidth presumed as mentioned is compared to a second bandwidth used which the second communication apparatus (B) currently uses. The first bandwidth and the second bandwidth are then adjusted, and a third bandwidth which the first communication apparatus (A) uses at data transmission and a fourth bandwidth which the second communication apparatus (B) uses are determined.

  • Publication number: 20110162623
    Abstract: Needles include a cylindrical outer needle that is brought into contact with and moved away from a nozzle body (113) to open and close an injection hole (1132) and an inner needle (112), slidably inserted in the outer needle (111), that is moved into and out of a sack-tip-portion space (171). When the inner needle (112) enters the sack-tip-portion space (171) and completely occupies the sack-tip-portion space (171), the fuel injection direction B is made downward relative to the injection-hole central axis C. Thus, it is possible to control the fuel injection direction B by controlling the amount of lift of the inner needle (112).
