Abstract: The present invention relates to novel mesylate salt of N-(5-(4-(4-((dimethylamino)methyl)-3-phenyl-1H-pyrazol-1-yl)pyrimidine-2-ylamino)-4-methoxy-2-morpholinophenyl)acrylamide, a novel crystalline form thereof, and a process for preparing the same. More specifically, the present invention relates to mesylate salt of N-(5-(4-(4-((dimethylamino)methyl)-3-phenyl-1H-pyrazol-1-yl)pyrimidine-2-ylamino)-4-methoxy-2-morpholinophenyl)acrylamide, which is excellent in stability, solubility, and bioavailability when it is administered not only alone but also in combination with other drugs and which has a high purity, a crystalline form thereof, and a process for preparing the same.

Abstract: A cathode ray tube comprises a panel having a fluorescent formed on an inner surface thereof; a funnel fastened to the panel; an electron gun housed in the funnel, emitting electron beams; a shadow mask for selecting colors of the electron beams; a mask frame for supporting the shadow mask; and a mask spring for coupling the mask frame to the panel, wherein the mask spring is comprised of an fastening portion welded to the mask frame, a attaching portion attached to the panel, and a connecting portion for connecting the fastening portion with the attaching portion, and elongated embossments are formed on a bending portion formed between the fastening portion and the connecting portion.

Abstract: The color cathode-ray tube includes a panel having a fluorescent screen formed on the inner surface thereof, a funnel coupled to the panel, an electron gun mounted into the neck portion of the funnel for emitting electron beams toward the fluorescent screen, and a shadow mask mounted on the fluorescent screen formed on the inner surface of the panel and having a predetermined distance from the fluorescent screen for carrying out color selection. The shadow mask is in a rectangular shape having a longer axis and a shorter axis and including a plurality of beam through apertures. The vertical pitch of the beam through apertures is between 0.15 mm and 0.35 mm. The vertical pitch of the beam through apertures increases as it goes from the central portion to the end portion of the shorter axis of the shadow mask.
