Title: Digital-to-analog converter
Inventor: REIMONDO SHII BURATSUKUHAMU
IPC: H03M1/06
Filed: 1990-11-27
Abstract: PURPOSE: To facilitate precision of a digital-analog converter by connecting a digital noise signal to an input digital signal, converting a digital signal, a connecting digital signal to a first and a second analog signals and subtracting the first analog signal from the second analog signal. CONSTITUTION: A digital signal to be converted into an analog signal is impressed to a digital signal input 12, and digital random numbers with the same width from a random noise generator 14 are added to each sample of the input digital signal by a digital adder 16. Next, the digital signal of a sum and the digital random number are converted into analog signals using a second DAC 20 and a first DAC 18, respectively. Then an analog connecting circuit 22 subtracts the digital random number converted into the analog signal from the signal of sum converted into the analog signal and generates the input digital data signal, converted into the analog signal as an output signal. Consequently, distortion of the digital-to-analog converter(DAC) is suppressed.

Title: On-line character recognizing device
Inventor: NISHIKAWACHI HITOSHI
IPC: G06K9/62
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To recognize a half size character preferentially and to improve the character recognition rate when the duplicate characters of the same shapes are recognized in a half size input mode. SOLUTION: The characters which are inputted in half or full sizes are converted into a coordinate data string S11 by a tablet 11 and then converted into a coordinate data string S12 by a preprocessing part 12 via the linearization processing. A feature extraction part 13 extracts the input character value S13 out of the string S12 to show the input character features. A matching part 14 calculates the distance value S14 between the feature value S13 and the feature value S18 of every character pattern registered in a character dictionary 18. When the input mode information on an input mode decision part 19 shows full size characters, a weighting distance value conversion part 15 sends the value S14 to a sorting part 16 together with the character codes.  If the input mode information shows the half size characters, the part 15 multiplies the value S14 by a weight coefficient and sends it to the part 16 together with the preceding character codes.
