Abstract: A bicycle front derailleur is provided with a mounting fixture that is configured to maintain an angular orientation of the front derailleur about a mounting axis parallel to a center axis of a frame tube in a stable manner. The mounting fixture has a bicycle frame fastening part, a front derailleur mounting part and a front derailleur contact part. The bicycle frame fastening part is configured to be fastened to the seat tube. The front derailleur mounting part is disposed on the bicycle frame fastening part and configured to be fastened to the front derailleur so that fine adjustment is possible about the mounting axis disposed at a distance from the seat tube. The front derailleur contact part selectively contacts a side surface of the front derailleur on the side facing the seat tube in a position that is different from that of the front derailleur mounting part.

Abstract: An object of the present invention is to produce images devoid of band artifacts. Data acquisition in SSFP is repeated N times (where N denotes the power of 2) in order to acquire data fv(k), which ranges from data fv(0) to data fv(N−1), from views v constituting a k-space. At this time, the phase of an RF pulse is varied based on an expression of 360°·v·k/N. If an operator designates Fourier transform imaging, a Fourier transform is performed on data fv(k) relative to each of the phases indicated by the RF pulse in order to produce data Fv(n). If the operator does not designate Fourier transform imaging, the data fv(k) is regarded as the data Fv(n) as it is. Any of at least either of weighted addition and MIP processing and root-mean-square conversion selected by the operator is then performed on the data Fv(n) in order to produce data Av. An image is reconstructed based on the data Av.

Abstract: In an authentication method for using a plurality of Web servers to allow only a user in a certain group to access information in the Web servers, a first Web server has a restricted access domain that only the user in the certain group is allowed to access from a client terminal, and does not have authentication information regarding the user. A second Web server has the restricted access domain that only the user in the certain group is allowed to access and further has the authentication information registered thereto. The first Web server delivers an authentication request to the second Web server. Based on authentication results determined by the second Web server, the first Web server allows the user to access the information. As a result, it is possible to reduce both user's work load for using a Web server to which the authentication method is applied and administrator's work load for managing the Web server.

Abstract: Operation of a network which comprises a plurality of mutually connected subordinate-networks is performed. Operation information is unitarily managed transmitted and received in the entirety of the network. An information storing unit stores operation management information used for the network operation management. A communications unit transmits and receives the operation information. Control is performed so that when the operation information is received from a subordinate-network, updating processing is performed if the contents of the operation information should be affected in the operation management information, and, operation information for reporting is produced and distributed to needing subordinate-networks based on the operation management information if reporting processing should be performed.
