Abstract: A resin film is formed on the surface of a hot dip galvanized steel sheet by applying emulsion of a polyolefin copolymer resin molecular-associated by ion cluster to the steel sheet surface. The resin film contains, in terms of solids content, 10 to 55 mass % of silica particles, 1 to 8 mass % of a crosslinking agent, and 1 to 8 mass % of tannic acid and/or ammonium vanadate. The resin-coated hot dip galvanized steel sheet is capable of exhibiting well-balanced superior characteristics in weldability, corrosion resistance, and machinability.

Abstract: The present invention relates to a photocurable resin composition which contains a photocurable component and forms on a substrate a photocurable resin layer having a viscosity of 1000-500,000 Pa·s at 23° C. and 65% RH. This resin composition is formed into a photocurable resin layer, which is laminated onto a metal sheet to give a metal sheet with a photocurable resin layer laminated thereon. This metal sheet can be worked and converted into a metal part with a high-hardness protective coating laminated thereon upon irradiation with light or electron beams after working.

Abstract: In a cathode ray tube apparatus having an in-line type electron gun, magnetic pole pieces comprising four pole pieces of substantially arc-shaped cross section are disposed in a cylindrical shape with circumferential gaps between neighboring pole pieces 0.degree., 90.degree., 180.degree., and 270.degree. locations on the cylinder. An additional pair of narrow width stripe-shaped pole pieces are disposed inside said cylinder at a predetermined distance from the cylinder in a manner to cover the 90.degree. and 180.degree. gaps. The apparatus acting to modify the horizontal and vertical deflection magnetic fields so that the electron beam spots on the phosphor CRT screen are substantially circular in shape without losing the self convergence effect of the magnetic fields.
