Filed: 1983-02-23
Abstract: PURPOSE:To make the beam width of vertical and horizontal polarized waves equal by making the length of lines of intersection of two orthogonal polarized planes and a spiral antenna different. CONSTITUTION:The length along a curve between points A and C, B and D, E and G, and F and H is a half wavelength respectively. The length of a line of intersection between the horizontal polarized wave 5 including the center of feeding points 1, 2 and the spiral antenna is made shorter than that between the vertical polarized wave 4 and the spiral antenna. Thus, the beam width of the radiation pattern by the wave source of the points A, B, C, D is made equal to that of the points E, F, G, H. It is possible to avoid the effect of the array factor by adopting a rectangular or an elliptic form in addition to a gourd- shaped form.

Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To artificially express gradation of input data, and obtain high brightness by generating display data on which the bit number is fewer than the input data by performing error diffusing processing on the input data. SOLUTION: An input image signal is converted into a digital image data by an A/D converter 1. The digital image data is 8-bit data capable of expressing 256 gradations. This 8-bit digital image data is sent to an error diffusing processing part 2. This error diffusing processing part 2 obtains 3-bit display data which is output data capable of artificially expressing gradation of input data by an error diffusing method and on which the bit number is fewer than 8-bit input data. In this way, since the 3-bit display data can be obtained from the 8-bit data by error diffusing processing, 256 gradations are artificially expressed by this 3 bit display data. Therefore, gradation of input data can be artificially expressed, and high brightness can also be obtained.
