Abstract: A font generation apparatus comprises a memory in which font data, which represents a matrix of dots or the outline of a font, is stored. The logic states of the stored bits are converted so that a bit pattern created by the converted bits represents a reflection of the bit pattern of the originally stored font data with respect to a line which equally divides the matrix, and the logic states of the bits stored in the memory are further converted so that a bit pattern created by the further conversion represents a rotation of the reflected bit pattern by 90 degrees.

Abstract: A pressure sensitive recording sheet having thereon a layer of fine oil microcapsules produced by the process which comprises dispersing or emulsifying finely in a polar solvent an oily liquid containing a substantially colorless color former capable of reacting with a developer to form a colored product and a polyisocyanate adduct having a free isocyanate group and adding to the dispersion or emulsion of the oil droplets a polyamine or a polyamine adduct having a free amino group as a polymerization promotor, whereby the polymerization of the polyisocyanate adduct is caused from the outer side of each oil droplet to encapsulate the oil droplet by the insolubilized polyisocyanate adduct. By this process the size of the microcapsules can be controlled quite easily.
