Patent JP-2004504573-A (JP)
IPC: F16H15/42
Filed: 2001-07-18
Abstract: The invention comprises a belt drive ring CVT coupler. Drive rings are rotatably connected to each end of a frame. Belts are trained around the drive rings. The relative spatial arrangement of the axis of rotation of each set of drive rings is maintained by the frame, which holds the drive rings in a pre-determined relationship between the pulley sheaves. The drive ring on the driver pulley turns in the same direction as the driver pulley through frictional contact with the sides of the CVT driver pulley sheaves. The drive ring on the driven pulley side rotates in the same direction to the drive ring on the driver pulley, since they are mechanically connected by the belts. The driven drive ring is then in frictional contact with the sides of the driven pulley sheaves, thereby driving the driven pulley. The effective diameter or radius of each pulley is adjusted by movement of the pulley sheaves. Axial movement of the pulley sheaves causes the axis of rotation of each drive ring to move eccentrically with respect to the axis of rotation of its respective pulley. Since the drive rings are mechanically connected, the drive rings move with the frame as a unit in response to the movement of the pulley sheaves, thereby changing the effective gear ratio of the transmission.

IPC: H04L12/56
Filed: 2002-01-31
Abstract: A radio communication system includes a primary station which is arranged to transmit a series of data packets to a secondary station which operates according to an ARQ scheme for acknowledging correct reception of each packet. The primary station transmits error correction information relating to any packets that are not received correctly, thereby enabling the secondary station to extract correctly the data. The data packets are transmitted via a plurality of logical channels, so that an error in transmission of one packet does not hold up transmission of packets in other channels. Transfer of data transmission from one primary station to another is done by transferring each channel when correct reception of a data packet on that channel has been acknowledged, thereby avoiding the extra signaling required in transferring logical channels in which a data packet has been received in error and the error correction transmissions have not been completed.

Abstract: <P>PROBLEM TO BE SOLVED: To accurately measure the concentration of a light absorptive substance in blood in measurement by pulse photometry.  <P>SOLUTION: Light of two wavelengths emitted from a light emitting element and transmitted through organism tissue is converted into an electric signal and processed to reach a CPU as the transmitted light intensity of each wavelength.

The CPU determines the mutual ratio Φ12 of the extinction degree variation parts ΔA1, ΔA2 of the respective wavelengths caused by blood pulsation, from the transmitted light intensity It1, It2. The CPU further determines the direct current extinction degrees Adc1, Adc2 based on the organism transmitted light intensity It1, It2 and the previously measured incident light intensity Ii1, Ii2.
