Abstract: The present invention provides a recording apparatus that generates a transport stream so that a boundary between recording units (aligned units) and a file division point (i.e., a boundary between GOPs) always coincide with each other without obtaining information on the file size or the like. When generating a transport stream by time-division multiplexing transport packets, n or more transport packets (e.g., null packets N) other than a video packet are inserted between a video packet group generated from a single encoding unit (GOP) and a video packet group subsequent to the video packet group. When d indicates the data length of the transport packet, h indicates the data length of a fixed-length header added to each of the transport packets before being recorded on a data recording medium, and L indicates a recording unit length to the data recording medium, L?(n+1)×(d+h) is satisfied.

Abstract: A user-manager server device includes: registration information on a local group including a domain user separately from a domain group managed by a directory server device, and authorization information on the domain group, the domain user, and/or the local group. When a logged-in user belongs to the local group, an authorization processing unit transmits the authorization information on the local group to a multifunction periphery (MFP) as the authorization information corresponding to the logged-in user. When the logged-in user does not belong to the local group, the authorization processing unit transmits the authorization information on one of the domain group and the domain user to the MFP as the authorization information corresponding to the logged-in user.

Abstract: If a logged-in user to a host terminal device succeeds in user authentication via a directory server device, a user-manager server device transmits a job ticket and authorization information corresponding to the logged-in user to the host terminal device. The host terminal device receives the job ticket and the authorization information, generates a job execution instruction responsive to the authorization information, and transmits the generated job execution instruction to an image forming apparatus along with the job ticket. When the job execution instruction is received from the host terminal device, the image forming apparatus executes a job specified by the job execution instruction if the job ticket received along with the job execution instruction is determined to be valid.

Abstract: A turbo blood pump includes a housing 1 having a pump chamber 2, an inlet port 3, and an outlet port 4, an impeller 5 disposed rotatably in the pump chamber, an upper bearing 9 and a lower bearing 10 supporting the impeller rotatably, and a driving force transmitting unit for driving the impeller to rotate. The upper bearing is supported at a position in the pump chamber below the inlet port, so that a cross-sectional area of the pump chamber in a plane including an upper end of the upper bearing and being orthogonal to a shaft of the impeller is larger than a cross-sectional area of a flow path of the inlet port at a portion where the inlet port is coupled to the pump chamber, and thus obstruction with respect to blood flow by the upper bearing is of such a degree as to be permissible from a practical viewpoint, while an impeller is supported by upper and lower bearings. Thereby, the pump is less likely to cause problems of blood stagnation and thrombus formation.

Abstract: A turbo blood pump includes a housing, an impeller rotatably disposed in a pumping chamber, bearings for rotatably supporting the impeller, a rotor provided outside the housing and rotationally driven by a motor, driven magnets mounted on the impeller, and driving magnets mounted on the rotor. The driven magnets and the driving magnets face each other via a wall of the housing to form magnetic coupling. The driven magnets and the driving magnets are arranged so that a direction of the magnetic coupling inclines with respect to a rotation axis of the impeller. The pump ensures sufficiently strong magnetic coupling between an impeller and a rotor and effects reduced load on a lower bearing supporting the impeller and little risk of hemolysis and blood stagnation.
