Title: Method and device for correcting character recognition result and recording medium
Inventor: ISOYAMA HIDEYUKI
IPC: G06K9/62
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a character recognition result correcting device capable of accurately correcting a place name word including 'AZA' (section of village, 'OAZA' (larger section of village) or the like while suppressing the increment of dictionary size. SOLUTION: Characters such as 'AZA' and 'OAZA' allowed to be added without practically changing the meaning of each word are set up as a redundant word and defined in a redundant word storing part 12. A recognition candidate character setting part 10 applies character recognition to a character string image and a character judging part 11 judges whether a redundant word is included in a recognized result or not. When a redundant word is included, a shifted position setting part 13 adds a new character string obtained by deleting the redundant word as a recognition candidate character string to be compared/collated with recognition words in a word dictionary 15. When the recognition word concerned exists, a DP matching part 142 inserts the redundant word into an optimum position and outputs the inserted result as a corrected result.

Title: Detection of reverse ionization in electrostatic precipitator
Inventor: TERAI HIROSHI
IPC: B03C3/74
Filed: 1981-10-16
Abstract: PURPOSE:To prevent the degradation in the dust precipitation efficiency of dust precipitating electrodes in an electrostatic precipitator by detecting the reverse ionization phenomena generated in the dust precipitating electrodes from the waveforms of secondary voltages and decreasing the applied voltage thereby removing the electric charge accumulated in dust layers. CONSTITUTION:When the electric resistance of dust exceeds 1X10<11>OMEGA.cm on accumulation of the dust on dust preciptating plates during the operation of an electrostatic precipitator, reverse ionization phenomena take place, and the dust precipitating performance is considerably degraded. In this time the instantaneous value of the secondary current observed by the condenser function of the dust precipitator is the value wherein photoelectric current is superposed on the true corona discharge current. The peak voltage of the waveforms of said secondary voltage and the instantaneous value of the voltage thereafter are detected and are compared with the boundary voltage of the reverse ionization determined as a function of the peak voltage. According to the difference in the compared values, the presence or absence of the generation of the reverse ionization phenomena is detected. When the reverse ionization phenomenon arises, the applied voltage of the dust precipitator is decreased to remove the electric charge accumulated in the dust; thereafter the voltage is applied again to prevent the degradation in the dust precipitating performance.

Abstract: PURPOSE:To uniformly cool two storage boxes by constructing a refrigerator such that the cool air cooled by a cooler circulates after branched into two cool air portions, one for cooling an upper storage box and the other for cooling a lower storage box. CONSTITUTION:The cool air blown out from a cooler 28 toward a back passage 36 flows down after branched to first and second cool air passages 52 and 54, respectively. The cool air flowing down the passage 52 enters an upper passage 56 and conducts a heat exchange while being brought into contact with the back and bottom faces of an upper storage box 22. After flowing out into side passages 46 and 46 via holes 60 and 60 formed in shielding members 38 and 38, respectively, the cool air flowing in the passage 56 rises and returns to the cooler 28 while being in contact with both side faces of the upper storage box 22. The cool air flowing down the passage 54 collides with a mid feather wall 42 and is fed into the upper circulating passage 58a of a lower passage 58. Then, after passing the tip of the mid feather wall 42 and a lower circulating passage 58b, the cool air flows into the back passage 36 again and is blown out into a bottom space 44 while being in contact with the back face of a lower storage box 24. Thereafter, the cool air cools the boxes 22 and 24 while rising in the passages 46 and 46, respectively, and returns to the cooler 28.
