A transmitting system which comprises a transmission line, a transmitting apparatus connected to the transmission line, and a receiving apparatus connected to the transmission line, and transmits data between the transmitting apparatus and the receiving apparatus, wherein the transmitting apparatus comprises packet compressing means which receives input data comprising plural packets having identifiers as an input, identifies packets to be discarded and effective packets according to the identif...

A transmission apparatus capable of executing an appropriate transmission power control in DPCH even when the DSCH and DPCH are multiplexed together. In the present transmission apparatus, DPCH transmission power control section 105 controls the transmission power of dedicated channel so that transmission power in periods corresponding to packet insertion periods of downlink shared channel becomes larger than that in other periods. Amplification sections 104-1 to 104-N amplify the transmission p...

Ideal nonlinear distortion compensation is realized by removing an imperfection of amplitude delay characteristic and an affection of inherent deviation that an amplifier has. A linear distortion compensation factor calculating part (18) estimates, based on quadrature demodulated signals (I'ch, Q'ch), the linear distortion characteristic occurring mainly due to imperfection of analog circuits, such as a quadrature modulator (13) and a high-power amplifier (14), and calculates and outputs a linea...

A torque transmitting structure extends along an axis and comprises a plurality of links connected end-to-end. Each link comprises a rigid spar transverse to the axis situated at one end of the link, a second rigid spar transverse to the axis and skew to the first spar situated at the other end of the link, and four connecting ties connecting the ends of these spars, thereby to form a link of generally tetrahedral form, the spars being common to adjacent links. The connection between spars and t...

Disclosed is a transmitting apparatus for transmitting a signal, which has been obtained by applying an inverse Fourier transform to a plurality of digital subcarrier signals having frequencies that differ from one another, after subjecting the signal to at least a digital-to-analog conversion. Frequencies in the vicinity of 0 Hz are not used as frequencies of valid subcarrier signals. Further, frequencies included in frequency ranges of f.sub.-M/2 to f.sub.-N/2, f.sub.M/2 to f.sub.(N/2)-1 are u...

A transmitting unit used for the transmission with a fixed transmission ratio. The external shape is similar to ordinary rolling bearings performs transmission with reduction of speed or increase of speed in a clockwise or counterclockwise direction, the input and output shafts being on the same axis. The transmitting unit comprises a dual eccentric sleeve, a transmitting race with equally divided radial grooves, with transmitting rods enclosing rolling members at both ends so that each covered ...

A transmitting chain is provided which can lower surface pressure between a bushing and a pin, which can well maintain a lubricating state, and which is high in durability so as to be capable of withstanding high load. A groove or a depression, into which lubricating oil, supplied from outside of the chain, is moved, is formed in at least one of a group including an inner peripheral surface of a bushing and an outer peripheral surface of a pin. A difference, space, or clearance, located between ...

A transmitting device generates a modulation signal depending on data to be transmitted. The transmitting device includes a transmission frequency generation device that is controlled depending on the signal in order to produce a transmission frequency corresponding to the modulation signal. A calibration device is provided for automatically calibrating the amplitude of the modulation signal during the operation of the transmitting device. This eliminates time-consuming and therefore costly adju...

A transmitting unit which uses bearings and the eccentric principle to reduce or increase the rotational speed. An eccentric portion is integrally formed with an input shaft, and a bearing is assembled along the outer periphery of the eccentric portion. The bearing is eccentrically moved when the input shaft is rotated. The bearing is surrounded by an integrally formed transmitting race, and plurality of radial holes are formed in the transmitting race. The same plurality of transmitting rods ar...

Disclosed is a ring network in which a plurality of transmitting apparatuses are connected in ring form so as to be capable of transmitting in each of upstream and downstream directions, working and protection channels are assigned to each direction and, when failure occurs in a transmission path, a transmit signal is looped back using the protection channel to effect rescue. The ring network includes an insert transmitting apparatus that incorporates a packet, which enters from a lower-order si...
