IPC: H04W48/16
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To realize excellent communication state with a base station by avoiding a situation that a degraded communication state lasts for a long time through a operation and an automatic research operation performed when the radio communication state is graded continuously over a prescribed time or over and to extend an available operating time of a battery by reducing power consumed for the operations above. SOLUTION: In the case that a monitor section 10 detects a radio communication state with a base station and detects that the radio communication state is consecutively in a degraded state for a prescribed time, the monitor section 10 allows an output section 6 to inform a user about it. Furthermore, when the monitor section 10 detects a radio communication state with a base station and detects that the radio communication state is graded consecutively for a prescribed time, the monitor section 10 conducts a retrieval operation to replace a present radio communication area with other radio communication area.

Filed: 1982-05-25
Abstract: PURPOSE:To reduce the load of a driving peripheral circuit, by generating a strong charge wall at the narrow part of a concatenated beads like pattern in order to apply its bias magnetic field component for a bias magnetic field component out of a hairpin like conductor. CONSTITUTION:Most minor loops 31 are provided in parallel with an in-plane magnetizable direction 10. Only the end part of a minor loop on a side opposite to a transfer gate part curves toward a direction 13 which divide halves an angle which is made by the direction 10 and the easy direction 12 other than the difficult direction 11. By doing so, a narrow part 31C of a pattern forms an acute shape in in-plane difficult axis direction, and a strong charge wall is generated at this part. Therefore, hairpin like coductor patterns 41, 41' and 41'', etc., are provided for the narrow parts 31C, 31C' and 31C'', etc., of the pattern, and connected in series. As the result, less driving current is required, and driving voltage necessary for it is low so that the load of a circuit for driving a magnetic bubble generator for testing can be reduced.
