Title: Picture processor picture processing method and storage medium
Inventor: KOBAYASHI MAKOTO
IPC: G06K9/00
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a picture processor, a picture processing method and a storage medium which avoid the processing delay caused by quality improvement of pictures and character recognition processing without requiring troublesome operation in accordance with modes. SOLUTION: In a facsimile mode, front data is substituted for stored code data and is transferred to a text buffer (omitted in the figure) in a RAM with respect to settles characters (unequivocally settled characters), and stored image date as a first candidate and image data in a range corresponding to unsettled characters are transferred to the text buffer as they are with respect to unsettled characters (characters for which plural candidates exist or any candidates don't exist), thereby omitting user's settling work. When the facsimile mode is not set, settlement processing of character recognition is executed (step S603) to improve the precision of character recognition, and pictures of high quality are obtained.

Title: Modified ink particle and production thereof, color filter and production thereof, color display, and apparatus for producing modified ink particle
Inventor: HORIUCHI TAKAHIRO
IPC: C09D11/324
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To obtain modified ink particles having satisfactory heat resistance, solvent resistance, resolution, and ink jet characteristics and capable of preventing the occurrence of pinholes, etc., by forming, on at least a part of the surfaces of ink particle bodies, a modified layer by depositing the vapor of a modifier on the surfaces of ink particle bodies being floating. SOLUTION: When the ink particle body 22 is hydrophilic like in the case of a color particle for a color filter of a liq. crystal panel, the modified layer 57 is pref. hydrophobic. When the ink particle body 22 is hydrophobic like in the case of a carbon black for a black matrix, the modified layer 57 pref. has a hydrophilicity, e.g. a hydrophilicity based on carboxy groups formed by the oxidation with nitric acid. The modified ink particles can be prepd. by floating ink particle bodies and depositing the vapor of a modifier onto the surfaces of the bodies to form a modified layer on the surfaces of the bodies. Thus, a color filter can be easily produced.

Abstract: PURPOSE:To obtain a lightweight metallic pipe having the prescribed length and thin wall thickness, by forming one end of a short-sized metallic pipe into a radially expanded part having thick wall thickness, and stretch forming the total length of the pipe by drawing the remaining part of it. CONSTITUTION:The 1st drawing is performed by pressing a metallic pipe 7 of short-sized blank material into the 1st die hole 5 having the 1st radially expanding part at its upper opening, by a punch 8 in a cold state. Successively, a perfect radially-expanded part is formed at the upper end of the metallic pipe 7 in the 2nd drawing state.

Title: Japanese syllabary to chinese character conversion system
Inventor: KOIKE TAKEO
IPC: G06F17/28
Filed: 1982-09-16
Abstract: PURPOSE:To reduce the capacity of a dictionary memory, by using dictionary memories separately for converting a monosyllabic and a polysyllabic KANA (Japanese character) string. CONSTITUTION:When a KANA string is inputted from the character key part 12a on a keyboard 12, a control circuit 11 discriminates between a monosyllable and a polysyllable. When it is the monosyllable, the circuit 11 refers to a monosyllable index memory 8 to retrieve address information and reads KANJI (Chinese character) information corresponding to the input KANA characters out of the monosyllable dictionary memory 7 by using the address information to transfer it to a selecting circuit 13. The circuit 13 processes and outputs the transferred KANJI information to a display device 14. When the input KANA string is a polysyllabic, the circuit 11 refers to a polysyllable index memory 10 to find address information, and reads KANJI information corresponding to the input KANA character string out of a polysyllable dictionary memory 9 by using the address information to transfer it to the circuit 13. The circuit 13 segments KANJI characters into polysyllables on the basis of the indication of the circuit 11 to output results to the device 14. Thus, sectioning marks are excluded from the memory 7.

IPC: H02M3/28
Filed: 1988-06-28
Abstract: PURPOSE:To reduce the capacity and the like by employing an NPN bipolar transistor as a diode for feeding spike energy produced upon turning OFF of a switching means to a capacitor. CONSTITUTION:A switching regulator applies DC voltage through a switching means, i.e., a transistor(TR) Q1, onto the primary winding T1 of a transformer T having subtractive polarity. The primary winding T1 is bypassed through the series circuit of a parallel circuit comprising a capacitor C1 and a resistor R1 and a bipolar TR Q2 having emitter and base connected through a resistor R2 and functions as a diode. The secondary winding T2 of the transformer is connected in series with a diode D2 and a capacitor C2 and the output voltage is obtained across the capacitor C2. Since the TR Q2 functions as a diode having forward direction as shown by the arrow, the capacitor C1 can be charged sufficiently.
