CONSTITUTION:The holes in a flat plate 1 for a shadow mask are arranged according to the following three formulae when the equivalent pitches in the central area are supposed to be PXO (in the direction of X-axis) and PYO (in the direction of Y-axis) and the equivalent pitches at the ends of diagonal axes are supposed to be PXE (closer to the direction of X-axis) and PYE (parallel to Y-axis): 1/3<1/2>PXO<PYO<=PXOX1.2, PXO<=PXE<=PXOX1.2 and PYO-50/2<=PYE<PYO (mum). After that, the flat plate 1 is formed into a curved surface thereby making a shadow mask. As a result, the balance between the resolutions of two directions is improved by maximizing the distances between beams on the screen in every direction. Moreover, it is possible to make a color picture tube to be easily manufactured.

Abstract: PURPOSE:To prevent the residence of a frame from being generated by comparing a transmission sequence number in a received communication frame with the latest sequence number stored in a sequence number table classified by every transmission origin, and deciding whether the received communication frame should be deleted or transmitted to another node. CONSTITUTION:When a communication frame is received at a reception part 12 from a line, the transmission sequence number is checked at a sequence number check part 121 by using the sequence number table 122 classified by every transmission origin. The sequence number of a corresponding node in the sequence number table classified by every transmission origin is taken out from a transmission origin address 182 in a reception frame, and it is compared with the sequence number in the frame. When the sequence number in the reception frame is larger than that of the table, it is decided as a new frame received first at the node, therefore, it is discriminated as an effective frame. When the value of the communication sequence number in the reception frame is equal to or less than the sequence number in the sequence number table 122 classified by every transmission origin, it is deletad, and no transmission to another node is performed.
