PROJECTION TYPE RECEIVING SET

PROBLEM TO BE SOLVED: To solve the problem in the conventional alumite coat formation treatment wherein fine roughness on a surface by an acid treatment as a pretreatment causes poor sealing in some cases and it leads to a liquid leak accident, further, it is required to clean a radiator before assembling to prevent that dye applied on the surface by black colouring treatment peals off from the surface to the liquid and this results in an increase in the number of assembling steps. SOLUTION: In the projection type receiving set of the present invention, a container filled with liquid is formed between a face side of a cathode ray tube and a projection lens disposed in front of the face side, and a fluororesin coat is applied and formed on a part or the whole of a surface of the container to the thickness of several micrometers through several decades of micrometers.
