The radio communication system includes: a transmitter that transmits a first polarized signal and a second polarized signal to a receiver and terminates the transmission of the second polarized signal in accordance with an instruction from the receiver; and the receiver that receives the polarized signal from the transmitter, determines whether or not a reception quality of the second polarized signal becomes lower than a threshold value, and issues an instruction to the transmitter to terminate transmission of the second polarized signal to the transmitter when the reception quality becomes less than the threshold value.

Radio communication system and controlling method thereof

A digital modulating and demodulating device is compatible with both PDH and SDH signals by dividing and combining input signals in many directions with a matrix switching unit. The digital modulating and demodulating device is provided as a combination of two conventional PDH device with an SDH mapping circuit, an SDH demapping circuit, and an SDH interface for allowing SDH signals to be input to and output from the digital modulating and demodulating device. Since the matrix switching unit is capable of dividing and combining input signals in many directions, the digital modulating and demodulating device simultaneously provides interfaces for inputting and outputting a PDH baseband signal and an SDH signal, and makes it possible to combine conventional separate device for PDH and SDH signals with each other.

Digital modulating and demodulating device which is compatible with both PDH and SDH signals by dividing input signal in multiple directions and combining input signals from multiple directions with matrix switching unit

In an ADM device, first and second modulators and first and second demodulators are provided as a mod/demod device for radio communication, first to fourth SDH interface circuits and first and second SDH mapping/demapping circuits are provided for processing SDH signals, and path switching is performed by means of first and second signal branch circuits and first and second signal switches to enable simultaneous processing of both modulated signals and SDH signals. This configuration eliminates the need for outside mod/demod devices for radio communication when forming a radio network and therefore reduces the cost of constructing a system. In addition, the ability to simultaneously process modulated signals and SDH signals enables the simultaneous construction of an optical and radio network.

A sheet original feeding apparatus includes a pair of spaced core members, a frame for rotatably holding the core members, and an elongated sheet having each end connected to the core members, wound around one of the core members, and adapted to hold a sheet original therein. A driver reversibly drives the core members, and a controller controls the driver to unwind the elongated sheet, thereby stopping the sheet original at a predetermined position.

Sheet feeding method and apparatus

An automatic transmit power control (ATPC) method and system for radio equipment of a cross polarization interference canceler system (XPIC system) wherein two orthogonally polarized waves of the same frequency channel are used independently of each other. The transmit powers of the polarized waves of the object frequency channel are simultaneously increased when a drop of the receive signal level of at least one of the two polarized waves of the object frequency channel is detected.

Original reading apparatus

This invention relates to a recording apparatus having a function for reading data on an original, and a function for recording an image corresponding to read data. The recording apparatus of this invention has: an original read unit for reading data on an original; a record unit for recording an image corresponding to the data read by the original read unit on a recording medium; a device for reciprocating the original read unit and the record unit in a main scan direction; and a feed unit for synchronously feeding the original and the recording medium in a sub-scan direction. The original read and record units are moved in the main scan direction, and the original and the recording medium are synchronously fed in the sub-scan direction to record an image corresponding to the data on the original on the recording medium.

Recording apparatus

The light from an original is reflected by first, second and third mirrors in succession. The light from the third mirror is imaged on an image sensor by a lens. The second mirror, as compared with the first and third mirrors, is disposed far from an original illuminating light source. The optical path among the first, second and third mirrors and the lens is a zigzag.

A printing or recording apparatus wherein a recording head is detachably mountable to the printing apparatus. The head is movable when mounted in the apparatus along a line on recording paper. The recording head includes an image bearing member. The image bearing member carries a developed image which is provided by forming an electrostatic latent image thereon and developing the latent image. The latent image corresponds to the information to be recorded. The recording paper is intermittently advanced. While the recording paper is at rest, the image bearing member rolls on the recording paper along the direction of the line to transfer the developed image onto the recording paper.
