Title: Key word extracting method for image document
Inventor: GOTO ATSUYUKI
IPC: G06F17/30
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a key word extracting method which guarantees that an extracted key word has only an error within a permissible range even if a text converted by an OCR(optical character recognition) has an error. SOLUTION: A plaintext and accuracy file generation part 6a extracts a character code included in character information as a 1st candidate and accuracy information from candidates for character information included in an OCR result file 5 generated through the character recognition of an OCR and generates a plaintext 6c and an accuracy file 6b. A key word extraction unit 6e generates a key word list 6g by taking a morpheme analysis of the obtained plaintext and key word extraction. A key word verification part 6f judges whether characters are misrecognized, one by one, from key words of high order in the obtained key word list 6g according to a previously set threshold value and excludes key words judged to be larger in the rate of the number of misrecognized characters than a specific condition from the key word list 6g.

Title: Ink jet recording method
Inventor: SAKAE MASAJI
IPC: B41J2/025
Filed: 1981-12-04
Abstract: PURPOSE:To develop steadily and surely ink particles that are constantly of the same dimension and improve the quality of picture images by establishing a frequency that is used for excitation of a nozzle at a value that is a little larger than the fluid resonance frequency of an ink. CONSTITUTION:A piezo-electric element 2 is installed on a nozzle 1. Excitation voltage the frequency of which is set at a frequency that is larger by 4.5-12% than a fluid resonance frequency of the ink 1 is supplied from the excitation source 3 to the piezo-electric element 2 to effect excitation. With this arrangement the pressurized ink 4 supplied to the nozzle 1 is vibrated and the ink 4 is jetted out as ink particles 7 from the tip of the nozzle 1 to charge between charging electrodes 8. Those electrodes 8 are deflected by deflection electrodes 10a and 10b to attach electric charge on a recording body 12 for recording. Setting up the excitation frequency of the nozzle a little higher than the fluid resonance frequency of the ink 4 prevents development of ink particles of small diameter. Ink particles of uniform size can be developed.
