Title: Data broadcast receiver
Inventor: KAWAMURA YUJI
IPC: H04N7/16
Filed: 2001-08-28
Abstract: PROBLEM TO BE SOLVED: To acquire information in excess of the number of simultaneously receptible channels from a digital television broadcast. SOLUTION: The data broadcast receiver capable of simultaneously receiving only data broadcast signals of the prescribed number of channels or below, receives a broadcast reception request of moving picture audio data and a broadcast reception request of service data, and determines whether or not simultaneously broadcast reception processing for the moving picture audio data and the service data is disabled. When the receiver determines it that simultaneously processing is disabled, the receiver takes precedence of the broadcast reception processing of the moving picture audio data over other processing and holds the broadcast reception processing of the service data, and acquires e.g. a network address of the service data when holding the reception processing so as to acquire the service data via a network.

Patent JP-2003088090-A (JP)
Title: Regenerative brake
Inventor: KATO HIROKAZU
IPC: H02K49/02
Filed: 2001-09-05
Abstract: PROBLEM TO BE SOLVED: To provide a regenerative brake which has a small size and a light weight even by increasing a brake force and which can efficiently generate thrust. SOLUTION: Since a disc part 16 of a brake disc 10 is exposed at a magnetic disc 162 to the surface of a good conductor disc 161, a magnetic gap due to a thickness of the disc 161 can be remarkably reduced, and a generated magnetic flux is increased as compared with the case that the whole disc surface 12 is occupied by a good conductor. An eddy current induced in the disc 161 is slightly reduced by decreasing its flowing route, but since a bar 161a is formed along the radial direction of the disc, thrust is generated in the tangential direction of the disc 10 by a current flowing in its direction, and hence a reduction in a current component for outputting an electromagnetic force of a rotative direction can be suppressed.
