Open the CIPO recordAbstract From the Canadian patent
A method of resistive sheet transfer recording is disclosed, in which the thermal diffusion coefficient of a resistive sheet (1) in the range of 1 to 100 x 106 m2/s is combined with that of an electrode head (2) in the range of 0.1 to 50 x 106 m2/s, thereby making it possible to form a high-quality image at high sensitivity and high speed.

Why it's free to use
- Filed January 15, 1990 and granted December 13, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 15, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 15, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
