Abstract

PURPOSE:To form a diaphragm plate having sufficient mechanical strength, easy handling and light in weight, by constituting a dome-shape by a plate composed of light metal and ceramic. CONSTITUTION:Composite plate member is formed with light metal foil 1 made of aluminum alloy and ceramic layer 2 formed with aluminum molten on the surface of the light metal foil 1. Although the diaphragm plate 10 formed into dome for the composite plate like this is ease to crack if it is made of the ceramic layer 2 itself, but if it is made a composite plate with light metal foil 1, the entire plate 1 is made rigid and easy for handling further, light in weight.
