Title: Image input system
Inventor: FUJINAWA MASAAKI
IPC: H04N1/403
Filed: 1987-05-15
Abstract: PURPOSE:To improve the throughput of input work, by providing plural image evaluation circuits which evaluate images at the time of being binarized with respective threshold value, and an arithmetic circuit which computes the optimum threshold value by using the evaluated values outputted from those plural evaluation circuits. CONSTITUTION:Multilevel picture data 111 is stored in a multilevel picture memory 200 transiently. The multilevel picture data 111 performs the binarization operation by using plural evaluated threshold values 910 stored in a threshold value parameter storage circuit 900 at image evaluation circuits 810-840, respectively, and evaluates binarized picture data. An optimum threshold arithmetic circuit 1000 performs the arithmetic operation of the optimum threshold value by using the evaluation data 811, 821, 831, and 841 of the image evaluation circuits. In case no arithmetic operation of the optimum threshold is obtained even by using the evaluation data, the threshold value obtained previously by the arithmetic operation is used. For that purpose, a threshold value register which stores the threshold value found by the arithmetic operation is provided in the optimum threshold value arithmetic circuit. At the time of applying or resetting a power source, the value of a reference threshold value set in the circuit is set at the threshold value register. The output of the threshold value register becomes the optimum threshold value 1010.

CONSTITUTION:The fluid Q is irradiated by radio wave or ultrasonic beam through wave receiver antenna A1-A3 of different depression angles theta-theta3 and the reflected wave is received, so that the doppler frequency fd1-fd3 proportional to the flow rate changing in accordance with cosine of deviation angle phi and cosine of the depression angle theta1-theta2 through the direction coupler C, the detector D1-D3 are detected. When the counted value corresponding to the frequency fd1-fd3 of the counters T1-T3 is processed by the operator U, the value corresponding to the doppler frequency fd0 in the case of the depression value being zero is determined. When the coefficient corresponding to cosine of the deviation angle phi is multiplied by the multiplier M, the flow rate is determined from the doppler frequency in the case of the depression angle being zero, and the precise flow rate can be measured without concerning the disposed position of antenna A1-A3 and the like.

Title: Dc voltage step-down circuit
Inventor: ADACHI HIROO
IPC: H02M3/155
Filed: 1979-09-17
Abstract: PURPOSE:To obtain a highly efficient inexpensive circuit with a simple construction by charging a plurality of capacitors in a series connection while discharging them by switching to parallel connection. CONSTITUTION:While a transistor TrQ2 is off by a signal from an oscillation circuit A, a base current flows to transistors Q3 and Q4 through resisters R1, R5 and R1, R7 to switch transistors Q3 and Q2 on followed by transistors Q5 and Q6. But since the current flows through the resister R1 at a very limited level, transistors Q1 and Q7 fail to turn on which causes the power source to charge the series capacitors C1 and C2. When the transistor Q2 turns on by the signal from the signal oscillation circuit A, the transistors Q1 and Q7 turn on while transistors Q3-Q6 turns off. As a result, a parallel circuit is so formed that the charge of the capacitor C1 is fed to a load R1 through a transistor Q7 and a diode D1 while the charge of the capacitor C2 is fed directly thereto. This enables the selection of the oscillation frequency as desired corresponding to the magnitude of the load thereby affording a highly efficient inexpensive DC voltage step-down circuit with a simple construction.
