  • Patent number: 10967157
    Abstract: A balloon catheter includes a shaft, and a balloon provided outside the shaft. A drug is provided on an outer surface of the balloon, and the balloon has at least a straight tube part. A change ratio of an outer diameter of the straight tube part, (D28?D24)/D24, is 1.1% or less. D24 is the outer diameter of the straight tube part when an internal pressure of 2.43 MPa (24 atm) is applied, and D28 is the outer diameter of the straight tube part when an internal pressure of 2.84 MPa (28 atm) is applied.

  • Publication number: 20080223927
    Abstract: An entry and exit control apparatus wherein missing entry and exit information on a user entering and exiting a controlled area by tailgating is complemented by entry and exit information on another user presumed to enter and exit the controlled area along with the user that is tailgating. Therefore, reliability of user entry and exit history is improved to sufficiently suppress a decrease in security in the controlled area.

  • Publication number: 20080126920
    Abstract: An method for creating an FMEA sheet includes the steps of, retrieving a plurality of documents, dividing words in each of the plurality of retrieved documents into a plurality of morpheme words by morphological analysis, calculating a co-occurrence frequency of each of the plurality of morpheme words, generating a co-occurrence frequency network with morpheme words having a greater co-occurrence frequency than a predetermined level in the plurality of morpheme words, grouping the plurality of documents using the co-occurrence frequency network, extracting a word same as an FMEA word registered in an FMEA word concept dictionary created in advance from each of the plurality of documents belonging to a same group as a word to be used in creating the FMEA sheet and substituting the extracted word to the FMEA sheet.
