  • Publication number: 20010021859
    Abstract: A forceps, comprising: a pair of forceps members, being able to open or close at one end, so as to put an object between them, and being supported at the other end thereof; a driving wire for transferring tension thereon to the forceps members for bringing them to open and close; and a driver portion for giving the tension onto the driving wire, wherein: one of the forceps members is built up with a member (A) 41, being able to open or close at one end, so as to put the object between them, while being supported to freely rotate at the other end, and the other member with a member (B) 42, being able to put the object between them, but being supported fixedly at the other end; the driving wire 44 is wound around a rotary portion at the other end of the member (A) 41, and a portion of the wound portion thereof is fixed onto the rotary portion; and a tension for open and close operation is given from the driver portion to one end of the driving wire 44.

  • Patent number: 4559633
    Abstract: A spread-spectrum communication system includes a transmitter for transmitting a spectrum-spread signal and a receiver for receiving the data signal. To establish synchronism between the signals transmitted and received, the receiver includes a first loop circuit for establishing synchronism in frequency and phase of a carrier for the spectrum-spread data signal, and a second loop circuit for detecting the synchronism of spectrum spreading code signal of a spectrum spread data signal after the carrier has been removed by said first loop circuit.
