change ink printed substrate is described which 
comprises providing a substrate, and then printing on 
at least one surface of the substrate a predetermined 
pattern of a light-transmissive phase change ink which 
initially transmits light in a non-rectilinear path. 
The pattern of solidified phase change ink is then 
reoriented to form an ink layer of substantially 
uniform thickness. This ink layer will, in turn, 
produce an image which then will transmit light in a 
substantially rectilinear path.  
     In one aspect of the invention, the substrate is 
light transmissive, and the reoriented printed 
substrate exhibits a high degree of lightness and 
chroma, and transmits light in a substantially 
rectilinear path. In this way, the reoriented printed 
substrate can be used in a projection device to project 
an image containing clear, saturated colors.

second selected window.
Patent EP-0378201-A3 (EP)
IPC: B41J2/35
Filed: 1990-01-10
Abstract: When a number of exothermic elements arranged linearly 
are used for printing, driving data are inputted to the gate 
circuits of each exothermic element, and the gate circuits 
are controlled by the strove signals in the 
conducting/nonconducting state. The circuit gates are 
divided into groups and the strove signals different for 
each group are inputted in sequence. At printing, when 
these is the group having a relatively small number or no 
exothermic elements being heated and driven, and the strove 
signal is given to each group successively for any groups, 
the necessary driving time may be wasted. The operating 
speed may be improved if a plurality of strove signals are 
outputted in parallel when the number of exothermic elements 
being heated and driven is relatively small, and if the 
corresponding strove signals are stopped when there is no 
exothermic element, and outputting the next strove signals 
immediately in both cases.

Abstract: A logic synthesis network for efficiently combining 
respective bit pairs of first and second operands to 
produce respective sum bits and a carry bit associated 
with the most significant sum bit. A dummy generator 
receives the respective bit pairs and generates first 
and second dummy sum signals, and first and second 
pairs of dummy carry signals. A first dummy selector 
chain selects the appropriate dummy sum and carry 
signals of all the bits other than the least signifi­
cant bit, as a function of the state of the first pair 
of dummy carry signals generated for the least signifi­
cant bit pair. A second dummy select chain selects 
the appropriate dummy sum and carry signals for all 
the bit pairs other than the least signficant bit 
pair, as a function of the state of the second pair of 
dummy carry signals generated for the least signifi­
cant bit pair. Sum generators associated with each 
bit pair choose between the selected dummy sum signals 
from the first and second dummy select chains in 
accordance with the state of the carry-in signal asso­
ciated with the least significant bit pair. Carry 
generators associated with each bit pair choose 
between the first and second pairs of dummy carry 
signals at the ends of the first and second dummy 
select chains, again in accordance with the state of 
the carry-in signal associated with the least signifi­
cant bit pair.
