IPC: G06K11/00
Filed: 1983-03-11
Abstract: PURPOSE:To input automatically a graphic pattern by superposing the pattern on measure printed in a color having an invalid input and binarizing the image of each measure and extracting and storing the presence/absence of an image in each measure and the features of the image. CONSTITUTION:The measures are printed in a color insensible as data, as shown by a dotted line, and a graphic pattern to be inputted is in another color is superposed, and a picture in each measure is read by a picture input device 6 to output binary picture data. A pattern memory 7 stores this binary data, and a feature quantity calculating processor 8 cuts out block along the measures and obtains a feature quantity on a basis of the number of a black picture element and its distribution condition in the block to store in a memory 12. An encoding processor 9 converts the obtained feature quantity to a code characterizing each block, and feature points are detected by a symbol cutting-out processor 11, and a symbol area such as a line (a), a branch (b), a bend (c) or the like which is signified with plural blocks is cut out on a basis of feature points. Thus, the input of graphic patterns is automatized.

Title: Masking method for color picture data
Inventor: ASADA SHINJI
IPC: H04N1/48
Filed: 1989-02-21
Abstract: PURPOSE:To obtain a natural copied picture by setting a masking equation for each of plural areas resulting from a color space divided by the saturation or the saturation and the brightness. CONSTITUTION:Primary color components B, G, R are inputted to an adder 1, a minimum value selection circuit 2 and a maximum value selection circuit 3. The adder 1 generates sub color components b, g, r being the subtraction of a brightness V outputted from the circuit 2 from each of the components B, G, R respectively. Moreover, an adder 4 subtracts the brightness V from the maximum value of the color component of the circuit 3 to generate a saturation CR. Mashing arithmetic circuits 5-7 apply the arithmetic operation corresponding to masking matrices ANR, AP and AHC to the sub color component to generate each combination of tentative secondary color components. Furthermore, the saturation CR and the brightness V are inputted to an adaptavility output circuits 8-10, where weight coefficients WNR, WP and WHC are generated. The tentative secondary component and the weight coefficient are inputted respectively to arithmetic circuits 11-13 and a processed color components y2, m2 and c2 are generated. They are added (14) to the brightness V to generate the secondary color component.

Title: Automatic white balance adjusting device of color video camera
Inventor: NAKAYAMA YOSHIAKI
IPC: H04N9/73
Filed: 1984-03-06
Abstract: PURPOSE:To easily adjust white balance by controlling the gain of an automatic gain controller corresponding to a color difference signal so that the difference between the color difference signal and a reference value is zero. CONSTITUTION:A comparator 18 operates either of analog switches 20 and 22 according to whether or not the level of a luminance signal Y is larger than a reference value Vref1. The switch 20 supplies the color difference signal R-Y to one terminal of a comparator 14 through an integrating circuit 12 and the switch 22, on the other hand, supplies a reference voltage Vref2. The reference value Vref2 at this time corresponds to the zero level of the color difference signal R-Y. The reference value Vref2 is supplied to the other terminal of the comparator 14. Consequently, the comparator 14 compares the integral value of the color difference part of a high brightness part with the reference value Vref2 and sends out a signal corresponding to the comparison result to an up/down counter 16 to control the gain of the automatic gain controller 6.

Title: Heat transfer tube of heat exchanger
Inventor: TOMOTA SHOSAKU
IPC: F22B37/04
Filed: 1986-02-28
Abstract: PURPOSE:To prevent the titled tube from being subjected to stress corrosion cracking by coating a tubular heat transfer substrate formed from a nickel base alloy with a tubular coat formed from a stainless steel. CONSTITUTION:A heat transfer tube 1 used in a heat exchanger is provided with a tubular substrate 2 made of a nickel base alloy such as inconnel, and tubular coats 3a and 3b consisting of an austenite stainless steel coating both the inner peripheral surface and outer peripheral surface of the substrate 2. The coefficient of thermal expansion of the nickel base alloy differs from that of the stainless steel, and the latter is larger than the former. Accordingly, depending upon the operationed state of the heat exchanger, the expansion of the stainless steel side is limited by the substrate of the nickel base alloy, and as a result, it is subjected to a compression stress. Therefore, the surface of the coat of stainless steel is not sensitive to the stress corrosion cracking and hence prevents the stress corrosion cracking from occurring.
