IPC: G02B6/38
Filed: 1979-04-25
Abstract: PURPOSE:To integrally from the receptacle without impairing the inside diameter accuracy of the circular pipe part by putting the flange part which has beforehand been made of the specified material into a die and integrally forming the circular pipe part by plastic material. CONSTITUTION:The flange part is beforehand made of material which does not receive any deformation during molding.
