A pair of rear side frames respectively comprise front bending-promotion portions, middle bending-promotion portions and rear bending-promotion portions which cause the rear side frames to bend inward, in a vehicle width direction, in a trough-folding shape in a rear collision of a vehicle, and a longitudinal distance L2 between the front bending-promotion portions and the middle bending-promotion portions is set to be longer than a longitudinal direction L1 between the middle bending-promotion portions and the rear bending-promotion portions. Thereby, there is provided a rear vehicle-body structure of an automotive vehicle which can properly absorb a collision load at a vehicle-body rear portion, even if a rear side frame is made from material which may not cause smooth bucking of the rear side frame.

The invention relates to a multifunctional drawing ruler which is formed by combining a primary ruler body and a secondary ruler body through a fixing button, wherein the primary ruler body and the secondary ruler body are marked with scales; the fixing button is provided with a hand screw, the primary ruler body is provided with a through groove, the two sides of a sliding block are provided with grooves, the groove on one side of the sliding block is provided with two fastening screws, the sliding block is connected with the through groove in the primary ruler body in a matched mode through the grooves in the two sides of the sliding block, the center position of the upper surface of the sliding block is provided with a through hole and a convex cylindrical buckle, the secondary ruler body is provided with a through groove, the length of the through groove in the secondary ruler body reach to the position of the fixing button, and the width of the through groove in the secondary ruler body is larger than the width of the through groove in the primary ruler body; a string is connected between the fixing button and the convex cylindrical buckle of the sliding block. When the multifunctional drawing ruler is used, an arbitrary angle, parallel lines, a circle, an oval and other geometric figures can be drawn as needed by moving the sliding block and the fixing button. The multifunctional drawing ruler is simple in structure and convenient to use and brings convenience to teaching of teachers and to learning of pupils.

With the use of a vector quantization technique, an index image, which is obtained by replacing an image on a block-by-block basis, each block consisting of a predetermined number of pixels, with any of a plurality of different pixel patterns and representing the pixel patterns by index values of the respective pixel patterns, is decoded by referring to a code book containing the pixel patterns and the index values of the pixel patterns in association with each other. When decoding an index image on the block-by-block basis into pixel patterns corresponding to the index values, the pixel pattern of each block is scaled, and additionally pixels near a contour in the pixel pattern after scaling are redrawn based on contour vector information corresponding to the pixel pattern.
