In drawing processing, a function liquid droplet ejection head is moved relative to a workpiece to selectively eject function liquid droplets from a plurality of nozzles of the function liquid droplet ejection head according to ejection pattern data. Calculation is made of an amount given to each of a plurality of imaginary divided portions obtained by partitioning in matrix a drawing region on the workpiece. Matrix data representing in multi-valued gradation the amount of function liquid given to the plurality of imaginary divided portions is generated. N-valued matrix data is generated by converting the matrix data into n-valued data (n≧2). The ejection pattern data is corrected to decrease and / or increase the amount of function liquid given to the imaginary divided portions.

Method and Apparatus for Joining a Pair of Electric Cables

An elastic tubular sleeve (8) in engagement with a tubular supporting element (9) is set to a substantially coaxial position around one of the electric cables (2a, 2b). Subsequently, the conductors (3a, 3b) of the cables (2a, 2b) are mutually connected to obtain a splicing region between said cables. The tubular sleeve (8) in engagement with the supporting element (9) is positioned around the splicing region. By use of a suitable apparatus (100, 101, 102) previously engaged on the sleeve (8) and the supporting element (9), the supporting element (9) is drawn out of the tubular sleeve (8) so as to cause a radial elastic shrinkage of the tubular sleeve (8) capable of inducing an axial ejection thrust on the supporting element (9) itself. Counter devices (12) associated with the apparatus (100, 101, 102) counteract the axial ejection thrust so as to allow the speed at which the supporting element (9) is drawn out of the sleeve (8) itself to be controlled.
