Title: Digital receiver
Inventor: ORIHASHI MASAYUKI
IPC: H03H17/02
Filed: 2001-03-21
Abstract: PROBLEM TO BE SOLVED: To keep satisfactory the characteristics of a demodulated signal obtained by demodulating processing to a received signal. SOLUTION: A signal (received signal) 150 received by a receiving part 101 is amplified by an amplifying part 102 and becomes an amplified signal 151. A distortion estimating part 103a estimates a distortion component contained in the amplified signal 151 while using information on the distortion characteristics of the amplifying part 102 and the amplified signal 151 from the amplifying part 102 and generates a correcting signal 152 for correcting the distortion component of the amplified signal 151 while using the estimated distortion component. A distortion compensating part 103b multiplies the correcting signal 152 from the distortion estimating part 103a to the amplified signal 151 and obtains a corrected amplified signal 153. The signal 153 is obtained by removing the distortion component from the amplified signal 151.  A demodulation part 104 provides a demodulated signal 154 by applying demodulating processing to the corrected amplified signal 153.

Title: Server and network printing service system
Inventor: IGARASHI TAKASHI
IPC: G06F3/12
Filed: 2001-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a server and a network printing service system, that can positively receive printing service order by preventing concentrated accesses to the server. SOLUTION: The network printing service system, located at a laboratory with five printers has first server 2, that receives information of printing orders from customers and a second server 3 that offers the information of the printing service to the customers. When the print order data, based upon the information obtained from the second server is sent to the first server by a terminal at the customer site and if the printing orders by the customers are concentrated at cretin times of the day, it is highly unlikely that a communication line becomes busy, since the second server offers only the information of the printing service. Since the first servers are located only at each laboratory and the print orders are distributed among those servers, it is also unlikely that the communication line goes into a busy state.
