Filed: 1992-07-08
Abstract: PURPOSE:To provide the color converted result keeping high picture quality with a little used chromaticity by deciding the converted gradation number of another color component for each picture element corresponding to the gradation number converted result of a certain color component. CONSTITUTION:While using a G component as a color component (a) and an R component as a color component (b,) first of all, the gradation number of the G component in an attentional picture element is converted into 3 gradations and corresponding to the result, the gradation number of the R component is converted into be decided to 2 or 3 gradations. First of all, G data 101 are inputted to a gradation number converting means 102, and an output G103 is ternary coded to any one of the three values of G1, G2 and G3. In this case, the conditions of G1=0, G2=8 and G3=15 are established. Next, the converted gradation number of R data 106 is decided. A conversion instructing means 104 outputs a conversion instruction signal 105 so that the converted gradation number can be '3' when the value of Gx103 is G1 or G3 and the converted gradation number can be '2' when the value is G2. While receiving the signal 105, an R gradation 107 ternary encodes the R data 106 to any one of R1, R2 and R3 when an R converted gradation number is '3' or binarizes them to either R1 or R3 when the number is '2' and outputs the result as Rx108. B data 109 are outputted as Bx=111.

Abstract: PURPOSE:To fabricate a system wherein errors are few in measurement and determination of position information with regard to a beacon transmitting apparatus in a road-vehicle information system. CONSTITUTION:A carrier wave signal 26 undergoes AM modulation with modulating signals 27 having the opposite phases, respectively. A radio beacon transmits the signals through two antennas 2 (2-1 and 2-2) having the mutually overlapped directivities in the directly downward directions.

Abstract: PURPOSE:To improve a great deal the drainage of water produced by dehumidification to a heat exchanger and attain a longer life of a metal die by making one surface of a plate shaped fin a hydrophilic surface layer made of a water glass family material and the other surface a hydrophilic surface layer made of a resin family material. CONSTITUTION:A hole for a heat transfer tube is pierced through a plate shaped fin 13 made of a precoated fin material which has on its one surface a hydrophilic surface layer 11 made of a water glass family material and on the other surface a hydrophilic surface layer 12 made of a resin family material, and fin collars 14 are erected with equal distance apart on the side of the hydrophilic surface layer 11 of a water glass family material. After inserting a heat transfer tube 15 through this collar it is tightly contacted and fixed to it. The air that flows into a heat exchanger is cooled and dehumidified. Because the surfaces of the fins are constituted with a hydrophilic surface layer, there is no water bridging between two adjacent fins, but it spreads on the fin surface as a water film and continuously discharges the dehumidifying water from the air. The cost is reduced by using a precoated material, and it is possible to attain a longer life of metal die and reduce maintenance cost because the fin collars are erected on the side of the hydrophilic surface layer of a water glass family material and the fins are always formed by pressing the resin family hudrophilic surface layer on a formed metal die.
