Title: Character recognition device
Inventor: KIYONO KAZUJI
IPC: G06K9/62
Filed: 1994-02-28
Abstract: PURPOSE:To provide a character recognition device with excellent real time performance in which a mis-reading rate is reduced through learning. CONSTITUTION:The character recognition device 1 has a recognition section (1st recognition means) 4, a discrimination section 6, a re-recognition section (2nd recognition means) 7, and a correction means 8. When the recognition section 5 decides a character pattern candidate with a highest similarity (evaluation value) in the reading stage, the judging section 6 judges the candidate. When the judging section 6 judges the candidate as a candidate liable to incur mis-reading, the re-recognition section 7 applies recognition processing to an input character pattern corresponding to the candidate. A correction means 8 corrects a judging criterion and a processing criterion so that the judging section 6 and the re-recognition section 7 make surer judgement and recognition based on the judging result by the judging section 6 and the recognition result by the re-recognition section 7 in the learning stage.

Title: Method for pumping liquid and device used therefor
Inventor: OGAWA SUSUMU
IPC: F04F1/18
Filed: 1988-02-10
Abstract: PURPOSE:To raise the upper limit of pumping and improve capacity by mixing compressed air with a liquid in a pumping pipe and reducing an average specific gravity to raise the liquid level of the pumping pipe and pumping up the liquid into a vacuum chamber utilizing difference in air pressure. CONSTITUTION:When both vacuum pump 13 and air compressor 20 are operated, the pressure in a vacuum chamber 11 is reduced while pressing in a compressed air into an air chamber 18. Thereupon, a rising flow of air-liquid mixture is generated inside a pumping pipe 10, pumping up a liquid containing deposit, solid materials, etc., into the vacuum chamber 11. As the liquid is stored in the vacuum chamber 11 making the air pressure in the vacuum chamber 11 higher than the outside air pressure, the check valve 16 of a discharge pipe 15 is opened to outwardly discharge the liquid in the vacuum chamber 11. That is, by mixing the compressed air with the liquid reducing an average specific gravity and pumping up the liquid utilizing difference in air pressure, the upper limit of pumping can be raised.

Title: Electronic circuit using crystal oscillation circuit
Inventor: SAKAMOTO TAKASHI
IPC: H03K19/00
Filed: 1978-03-17
Abstract: PURPOSE: To make low power consumption for MIS logic circuit, by inhibiting the operation of the complementary MIS logic circuit by the output of the crystal oscillator for a given period after the application of power supply through the use of the output of the time constant circuit.  
     CONSTITUTION: Since the output of the crystal oscillator 1 immediately after the application of power supply is the DC voltage at the intersection point between the input and output delivery characteristics of the inverter circuit and the straight line by the bias resistor Rf, MISFET Q 1 , Q 2  of the gate circuit 3 are turned on. However, the output of the time constant circuit 2 is at a low level immediately after the application of power supply, then MISFET Q 4  is turned off to prevent the occurrence of through-current. Further, since the output of the circuit 3 is at high level because FET Q 4  turns off and the input to the frequency divider 4 at the next stage is not at intermediate level, the through-current in the circuit 4 can be prevented and the consumed current can be decreased.

Abstract: PURPOSE:To enhance the thermal efficiency of annealing and lower the fuel unit by attaching many fins to the annealing pipe of a vertical type apparatus for continuously annealing a wire rod with steam. CONSTITUTION:Drawn wire rod 1 is annealed by passing through pipe 3 filled with superheated steam, and the annealed rod is water-cooled by passing through cooling water vessel 5. Pipe 3 has been set in the vertical type chamber lined with heat insulating material 11, and many fins 4 have been attached stepwise to the outside of pipe 3.

Water introduced into unit 14 from inlet 17 is converted into steam, which then enters pipe 3 from outlet 19 through inlet 25 of pipe 3. Air heated with exchanger 12 is used to turn fuel gas. Since the combustion gas slowly rises in the chamber owing to the presence of fins 4, the efficiency of heating fins 4 is enhanced to save the fuel.
