Title: Seal ring
Inventor: ABIKO TADASHI
IPC: F16J15/18
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To attain a long service life and improve sealing performance in a seal ring cut in one circumferential place. SOLUTION: Cutouts 25, 45 are provided on the inner diameter side of first and second circular arc shaped protruding parts 20, 40 of a seal ring 1. The radially thin-walled seal ring 1 is mounted in a groove at the periphery of a shaft and brought into pressure contact with the axial hole inner peripheral surface of a housing in the state of fluid pressure acting thereon. The first and second circular arc shaped protruding parts 20, 40 are thereby deformed bending onto the inner diameter side by pressing force from the axial hole inner circumferential surface so as to dissolve a radial clearance between the outer peripheral surface of the seal ring 1 and the axial hole inner circumferential surface of the housing, thus improving sealing performance.  The peak of contact surface pressure between the first and second circular arc shaped protruding parts 20, 40 and the axial hole inner circumferential surface of the housing is eliminated, so that wear of the seal ring 1 is uniformed to attain a long service life.

IPC: H04L27/22
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To eliminate a data error caused by fading caused in a radio channel based on the time diversity system. SOLUTION: In order to secure the time diversity effect by utilizing a transmitter-receiver using the 4-phase PSK modulation demodulation system, the transmitter side uses a data string without a delay and a data string delayed by a prescribed time to modulate a carrier frequency shifted by 0 and 90 deg. and adds them and sends the result. A receiver side uses a distributer 12 to divide the output of a receiver 11 into two and they are fed to demodulators 14, 15. A carrier recovery circuit 13 applies the carrier of 0 and 90 deg. to be recovered to the demodulators 14, 15, in which a data string without a delay and a data string delayed are demodulated.  The phases of the two data strings are made coincident by a delay circuit 16 and a data string without a data error in the two data strings is selected by error detectors 17, 18 and a selector 19 is outputted under the control of a control circuit 20.
