Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To reduce error occurrence rate, when a route is detected by sequentially raising the transmission power levels of the radio machine of a self-station and a repeater station and retransmitting a route request, when an error packet is received. SOLUTION: When a communication controller 202 transmits the packet of a route request and receives the error packet of the route request, it sends an instruction command to a transmission power control part 205 and raises the transmission power of a radio signal transmitted from the radio transmitter 203 by a prescribed level from a present level. The packet of the route request is retransmitted. When affirmation response packet of the route request is received, a data packet is transmitted, in accordance with a route contained in it. When the error packet is received, transmission power is raised sequentially from a repeater station near the self-station. Thus, a cover area is increased, and the route request is retransmitted.

IPC: H01T4/04
Filed: 1988-07-19
Abstract: PURPOSE:To prevent the breakdown of a bushing caused by adding a press contact force to the outer circumferential surface of the bushing collectively due to the edge part of the cap top end by providing a cap having the outer circumferential edge extended outward. CONSTITUTION:As a cap 3, those in which the outer circumferential edge 3c is extended outward to have a round form on the inside are used. The cap 3 is deformed and made in press contact with the taper face 1a of a bushing 1 by means of a pressure roll 4, but the top end edge part 3b is never brought into direct contact with the taper face 1a of the bushing 1, as the inside of the outer circumferential edge 3c of the cap 3 has a round form. Thus, the press contact force by the press roll 4 is never collectively added to a part of the taper face 1a of the bushing 1, and a spinning seal having an interposed ring seal member 2 is obtained. Hence, the cap top end edge part is never directly brought into contact with the taper face of the bushing, which can be prevented from receiving a damage.
