An implosion protected cathode ray tube which comprises a glass envelope having a faceplate; and a layered protective structure deposited over and positioned frontwardly of the faceplate. The layered protective structure includes a first resin-coated layer held in contact with the faceplate, a hard coated layer for protecting the first resin-coated layer and a second resin-coated layer formed between the first resin-coated layer and the hard coated layer. The first resin-coated layer has a hardness which corresponds to 1H or lower of hardness of drafting pencil lead, and an elongation at breakage within the range of 65 to 85%. The first resin-coated layer also has a break strength of 3.5 kilograms per square millimeter or greater. The hard coated layer has a hardness which corresponds to 5H or higher of hardness of drafting pencil lead, and an elongation of 3% or smaller at breakage. The second resin-coated layer has a hardness generally intermediate between the hardness of the first resin-coated layer and that of the hard coated layer and also an elongation at breakage generally intermediate between the elongation of the first resin-coated layer at breakage and that of the hard coated layer at breakage.

Cathode-ray tube with multi-layer resin coating on faceplate providing

A device for measuring the adhesive or shear strength of a coated film comprising: a fixed member which can be fixed on an object to be measured; a guide member fixed on the fixed member; a moving member which moves along the guide member in parallel with a measuring surface of the object to be measured; a cutting blade supporting member; a cutting blade mounted on one end part of the cutting blade supporting member and press-contacted on the measuring surface; a mechanism for adjusting the press-contacting force of the cutting blade onto the measuring surface; a mechanism for adjusting a pressure contacting angle of the cutting blade; and a pressure detector for detecting cutting resistance generated by the cutting blade. The device also comprises a vertical displacement detector for detecting a vertical displacement with respect to the measuring surface of the object to be measured.
