Title: Character recognition method
Inventor: NAKAJIMA TAMOTSU
IPC: G06K9/50
Filed: 1993-03-18
Abstract: PURPOSE:To obtain a character recognition method in which a dictionary can be easily generated by calculating the distribution of a chain code in the prescribed area with designated contour of a character image, and recognizing a character in detail based on the distribution. CONSTITUTION:A binarization processing part 1 binarizes image data, and a runlength data generating part 2 generates runlength data from binary image data, and a vertical phase expression data generating part 3 generates vertical phase expression. Also, a middle classification condition generating part 4 generates a middle classification condition by using the position of a run in the vertical phase expression. Furthermore, a chain code distribution generating part 5 generates chain code distribution normalized for a partial contour and normalized code length distribution, and delivers them to a character recognizing part 7, and the character recognition part 7 performs recognition processing based on the distribution. In such a way, since the dictionary can be generated from sampling data by using a statistical method, the dictionary can be easily generated.

Title: Crystal oscillation circuit
Inventor: ISHIKAWA TAKEHIRO
IPC: H03B5/36
Filed: 1978-05-18
Abstract: PURPOSE:To avoid the oscillation incapability due to the evil external factors such as the water by combining the input side of the amplifier circut to the terminal of one side of the crystal oscillator via the capacitor and then incorporating the capacitor into the IC containing the amplifier circuit. CONSTITUTION:The watch-use IC29 is formed with P-CHMOS21, N-CHMOS22, drain resistance 23, feedback resistance 24 and coupling capacitor C28 each. And crystal oscillator C15, C26 and C27 form the oscillation circuit. Capacitor C28 cuts off the leak, etc. of the DC component and transmits only the oscillation waveform. Accordingly, no fluctuation is caused to the bias point of the amplifier even in the case of the leak occurred. Furthermore, no leak occurs at the input side of the amplifier circuit since C28 is provided inside IC29, and the leak, if occures, is limited only at the connection terminal of C26. As the connection point of C26 has no relation to the bias point of the amplifier circuit, the oscillation is never stopped. Thus, an electronic watch can be obtained with low power consumption and high reliability.

Title: Self-suction type under-liquid air blower and pressurization thereby
Inventor: AOYAMA HIDEO
IPC: C02F3/20
Filed: 1980-05-06
Abstract: PURPOSE: To pressurize highly reactive gas to a high pressure by using a system in which liquid inside a casing is pressurized by rotation of impellers or the like and flowed into a nozzle into which gas is introduced in such a way as to generate a large amount of fine bubbles.  
     CONSTITUTION: A nozzle 2 connected with a gas introduction pipe 1 is fitted into a casing 3 in which a rotor 4 with an impeller 5 is fixed. When turning the impeller 5 or the rotor 4, liquid inside the casing 3 is pressurized against the inner surface of the casing 3 while being given an impulse in a circulating flow around the shaft and thereby flows with high speeds into the nozzle 2. Then, consequent upon said movement, a gas is flowed into the nozzle 2 from a hole provided in the side of the nozzle 2 and the gas-mixed liquid is injected from the nozzle 2. The gas-mixed liquid so injected is disturbed by the resistance of liquid outside the casing 3 to form fine bubbles. When the mixed fluid is separated in a liquid tank, the inside of the liquid tank is pressurized by gas introduced from outside.

Abstract: PURPOSE:To accurately detect an abnormal detecting terminal by adding the 3rd value of measurement that can be obtained from a relative formula decided by the static characteristics of a plant between values of measurement to the abnormality detecting algorithm of the detecting terminal. CONSTITUTION:The detectors 1-1,..., 1-i,..., 1-n connected to a control system 1 have the values of measurements X1-1,..., X1-i,... X1-n respectively. Under such conditions, a relation F(X1...Xi...Xn)=0 is satisfied in general among those plant state values X1,..., Xi,..., Xn owing to the static characteristics of a plant. Then X1'=F1(X1-2...X1-i...X1-n) is satisfied in diagnosis of the detector 1-1 by using the relation X2=X1-2...Xi=X1-i...Xn=X1-n and the value of measurement after taking notice of X1. Thus the 3rd value of measurement X1' can be calculated from the value of measurement excepting for the value of measurement X1-1. The value X1' is compared with the values X1-1 and X2-1 respectively to specify a certain abnormal signal.
