Abstract: In a transmission system having concatenated optical amplifiers (OA), gain saturation of the optical amplifiers at any stage is caused by the extraction of power from the amplifier by the ASE (amplified spontaneous emission) and amplification of the signal and of the ASE from previous stages. Three methods of operating transmission systems are classified as free-running, constant-total power and constant-signal power. Differences in performance of the three systems arise from the propagation of signal power and the buildup of the ASE. It is now disclosed that the buildup of ASE noise in a system of either lumped or distributed concatenated optical amplifiers can be limited by operating at least a plurality of the optical amplifiers to provide unsaturated gain which is greater than the loss of the system and/or each optical amplifier is operated in its saturated state.

Abstract: Known printing machines have been found to have poor printing quality if the direction of the printing sheet is reversed through the sheet becoming slack. 
     The present invention overcomes this by ensuring that the amount of play b2 of a first power transmission system (202, 203, 204, 208, 209) between said drive motor and said sheet discharging means is larger than the amount of play b1 of a second power transmission system (202, 203, 204, 205; 202, 203, 204, 205, 206, 207; 202, 203, 210, 211; 202, 401, 402, 403; 202, 401, 404, 405) between said drive motor and said sheet conveying means. 
     The difference in play may be achieved by dimensioning the backlash or the gear train used or by a rotation transmission gap in one of the shafts in the associated gear.

Abstract: Each of a plurality of base stations in a mobile radio communication system has a plurality of sectoral zones each having a directional antenna of horizontal directivity pattern. Radio channels are divided into as many groups as the number of sectoral zones per base station. The channel groups are assigned to the sectoral zones as the preferential allocation channel groups in such a manner that the same channel groups are assigned to the sectoral zones which have substantially the same directions determined by antenna directivity. When a request for communication occurs within a sectoral zone, channels are selected from the channel group assigned to the sectoral zone. If the carrier-to-interference power ratio of a selected channel is equal to or greater than a predetermined value, the selected channel is allocated. The mobile radio communication system thus has improved channel utilization efficiency to accommodate more traffic.

Abstract: A composite asynchronous/synchronous system switches signal paths at the time of a fault and uses a route diversity function even when a fault occurs in the asynchronous mode signal. The composite system includes asynchronous system fault notifying means (31) in each of the connection offices (13A) connecting the synchronous communication system and the asynchronous communication system. When an asynchronous system alarm indication signal AIS shows suspension of the asynchronous mode signal or a fault in the signal, the notifying means converts a fault detection signal to information recognizable in the synchronous mode and sends the information to an asynchronous system fault path switching means (32) which is provided in the path termination office (13B). The switching means detects the fault detection signal generated in the asynchronous mode, or receives the fault detection signal sent from the asynchronous system fault notifying means, and switches paths formed on ring-like transmission lines.

Abstract: A memory which can transfer data words in burst mode in either row or column direction. First, the memory is divided into two sections with odd words stored in one section, even in the other. This allows ping pong buffers to be reading one word from memory while the next is being accessed. Also, the page height is set to be an odd number of words. Therefore, when the entire page is read in or out, seccessive words in either the row or column direction will always be alternately odd and even. If a partial image is read into the memory, this odd and even relationship will also hold. If an image with an even number of rows is read in, in order to preserve the sequential odd-even sequence, in every other column of the original data successive words are swapped so that the word order becomes 1, 0, 3, 2, etc. Then the addresses are also generated in staggered order, so that the words go into the correct location in memory. In this way, the word order of loading and reading of data is always successively odd and even regardless of the size of the image.
