Abstract: <P>PROBLEM TO BE SOLVED: To provide an authentication processing method and an authentication processor capable of identifying whether a user uses specific equipment authorized to be connected besides authenticating the legal user and moreover dispensing with the delivery of a common key used for encrypting and decoding data.  <P>SOLUTION: In a subscriber office, a first password inherent in the equipment, and a second password inputted by the user, are combined to generate a first encryption key. In a base station, a third password and a fourth password held therein are combined to generate a second encryption key. The base station transmits an authentication request encrypted with the second encryption key, to the subscriber office. The subscriber office decodes the received authentication request using the first encryption key, recognizes it as the authentication request, and transmits an authentication response encrypted using the first encryption key to the base station. The base station decodes the received authentication response using the second encryption key to recognize the validity of the authentication response.  <P>COPYRIGHT: (C)2003,JPO

Title: Individual segment type bonding weight for correction
Inventor: GROSS PETER L
IPC: F16F15/32
Filed: 2002-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent frequent changes of a coil which is somewhat hard to handle. SOLUTION: A weight, which corrects the imbalance of a rotating element, contains the prescribed number of dispersion/arrangement type weight pieces. The number of the dispersion/arrangement type weight pieces are selected so as to generally correct the imbalance. One piece of a double coated tape has a sufficient length so that the prescribed number of the dispersion/ arrangement type weight pieces are bonded. The side of the tape, which is opposite to the side to which the dispersion/arrangement type weight pieces are bonded, is protected by a removable film. The film reduces the possibility of contamination until the removable film is removed so as to permit the mounting of the weight to the rotating element by exposing the side of the tape opposite to the side to which the dispersion/arrangement type weight pieces are bonded.
