This invention relates to novel 1,2-pyridazines, 1,6-pyridazines or pyrimidines of the formulawherein B1 to B3 and R1 to R7 are as defined in the description and in the claims, as well as pharmaceutically acceptable salts thereof. After having formed capacitors and diodes on an SOI, remove a silicon substrate of the SOI. 01 \u03bcm to about 10 \u03bcm, are held together as a thin-layered, handleable, and unified mass by a porous inert polymer material. Last, store the Gamma corresponding relationship of all major and minor sampling pixel data in the Gamma table. The validated records are partitioned based on a unique parameter.
