Title: Character pattern normalizing circuit
Inventor: TAKENAKA SHINYA
IPC: G06K9/20
Filed: 1984-08-10
Abstract: PURPOSE:To obtain always approximately equal binary pattern information per one character by controlling the clock frequency driving an image sensor though the relative moving speed of the image sensor to characters is changed. CONSTITUTION:When an image sensor 4 detects a character, character detecting circuits 81 and 82 of an image sensor moving speed detecting circuit 8 output signals. A clock counting circuit 83 counts the number of clocks between signals sent from circuits 81 and 82 to obtain an output CNT. A frequency variable clock generating circuit 9 connects the output CNT from the circuit 8 to several address lines of an incorporated ROM, and left lines are connected to a latch circuit. Thus, a numerical value corresponding to the scanning speed obtained in accordance with the address is preliminarily written as data in each address of the ROM to obtain easily clocks having a frequency corresponding to the scanning speed at each time. That is, approximately equal binary pattern information is always obtained per one character though the moving speed of the image sensor is changed.

Abstract: PURPOSE:To eliminate fluid noise and sharply reduce the electric current consumption of the title flowmeter by converting the mean value of sampling signals into a digital signal having a period longer than that of an exciting frequency and calculating the flow rate of a fluid by using the digital signal, and then, outputting the calculated flow rate as a flow rate signal. CONSTITUTION:When a flow-frequency exciting current If' is made to flow to exciting coils 11a and 111b, a signal voltage eSO' proportional to the flow rate of a fluid to be measured is outputted to the output terminal of a differential amplifier Q3. The voltage eSO' is sampled just before the current If' changes from positive to negative or from negative to positive and signals held by capacitors C2-C7 are added to each other by means of an addition amplifier Q5. Then the signals are converted into digital signals by means of an A/D converter 24 based on a timing signal ST6 having a period which is three times as long as that of the current If' and the digital signals are outputted to a CPU 23. Therefore, the converter 23 is refreshed in data at a rate of one time per a plurality of exciting periods. In addition, the CPU 23 performs various kinds of processes, such as flow rate calculation, actual flow rate conversion, etc., and outputs processed results to an output circuit 19.

IPC: H04N9/31
Filed: 1986-07-18
Abstract: PURPOSE:To correct color shading with high accuracy by using a part of a sinusoidal wave to correct the color shading caused by the reflection (transmission) directivity of a screen. CONSTITUTION:A resonance circuit 4 generates a sinusoidal wave signal synchronously with a horizontal deflection frequency and gives the signal to a 1st modulation circuit 5 and a 2nd modulation circuit 6, and in this case the polarity of the sinusoidal wave fed to the 1st modulation circuit 5 and the 2nd modulation circuit 6 is opposite to each other. A red signal fed to an input terminal 1 is subjected to amplitude modulation by a part of the sinusoidal wave fed from the resonance circuit 4 at the 1st modulation circuit 5 and the modulated signal is fed to a Red projection tube 7. A blue signal fed to an input terminal 3 is subjected to amplitude modulation by a part of a sinusoidal wave fed from the resonance circuit 4 by the 2nd modulation circuit 6 and the modulated signal is fed to a blue projection tube 9. Since the color shading caused by the reflection(transmission)directivity of the screen is corrected by using a part of the sinusoidal wave in this way, the color shading correction with high accuracy is attained.
