Title: Method for reducing transmission error in radio data
Inventor: KAWAKAMI EIICHIRO
IPC: G06F11/10
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To reduce a transmission error in radio data by receiving the radio data being data complex and applying inverse complex processing to the received data so as to effectively randomize an error producing interval. SOLUTION: Radio data being data complex (interleaver 2) are received via a propagation path 9, the plural lengths of consecutive error caused in the received signal are observed and the average length of the plural consecutive error lengths is calculated (burst error mean length detector 4) and combination of number of columns and rows in each 2-dimension arrangement memory is revised (memory matrix decision device 5) to conduct complexing (interleaver 2) and inverse complexing (de-interleaver 7) so as to reduce the transmission error of radio data, based on the mean length of the consecutive error lengths.

Title: Input/output control system for data processor
Inventor: MATSUYAMA NOBUHITO
IPC: G06F13/12
Filed: 1988-12-23
Abstract: PURPOSE:To effectively control plural devices to which the data transfer service is requested within a fixed time by reporting the retry status and opening once a channel in case the channel occupying time of the same device exceeds a prescribed time during execution of a chain command. CONSTITUTION:In case the value of a timer 13 exceeds its limit level with the start of a certain frequency, a microprocessor 11 resets the timer 13 to produce a retry status and reports this status to a higher rank BLMPX via a channel interface control part 14 in case a time-over is detected. Receiving the retry status, the BLMPX opens a channel to attain the service of other circuits. A circuit command once interrupted is restarted after a fixed time by reporting the device end status to the BLMPX. As a result, the continuous channel occupying time of a single device is automatically limited.

Abstract: PURPOSE:To improve the identification accuracy of similar characters as a candidate by pattern dictionary matching and to improve the reliability of the recognition result. CONSTITUTION:The 2nd, 3rd, and 5th candidate characters having no membership function from among candidate characters by the matching with the pattern dictionary are set in the order as they are.

The total is obtained as a synthesis value (processing 201). The (S) with the higher systhesis value is set as the 1st candidate and the (s) with the lower synthesis value is set as the fourth candidate (processing 206). Thus, the influence of the difference of the distribution of parameters for each character can be made little.
