Filed: 1985-04-25
Abstract: PURPOSE:To attain the ease of picture data input by using an output of a data head signal added to the head of an input picture so as to stop tentatively a data read synchronizing signal. CONSTITUTION:A reset signal B is outputted from an output port 11 of a thermal head drive circuit 1 ahead the picture data input and resets a shift register (not shown) of a thermal head 2. Then a data head signal C is read synchronously with a synchronizing clock F and the picture data is read.

Title: Method and device for supplying connection material to wiring substrate
Inventor: TANAKA TAKASHI
IPC: H05K3/34
Filed: 1994-04-27
Abstract: PURPOSE:To supply a connection material such as solder paste to an electrode on a wiring substrate with a fine pattern. CONSTITUTION:A mask is aligned and fixedly arranged on a wiring substrate provided with a wiring electrode 7. Solder paste is from a sprayer and an XY table on which the substrate is placed is operated, and the solder paste is supplied in a linear form on a mask by traversing an opening part 6 corresponding to the electrode 7 of the mask. The width (b) of the opening part in the direction perpendicular to that of the linear solder paste is larger than the line width (c) of the solder paste. Accordingly, in the supply of the solder paste to the electrode, as the two directions of the opening part 6 of the mask are larger than the line width of the solder paste, the solder paste may be extracted only to the remaining two directions of the opening part. Therefore, if the pattern is fined, it is possible to excellently supply the solder paste onto the electrode.
