Title: Production for information recording substrate
Inventor: MATSUMOTO YASUYOSHI
IPC: B29C65/08
Filed: 1984-02-20
Abstract: PURPOSE:To make a joint layer uniform to enhance the joining force and to shorten the joining time by forming an annular projecting part in a sticking part of one of surfaces of disc substrates and a spacer and joining the spacer and disc substrates by an ultrasonic welding method. CONSTITUTION:Triangular projections 8 and 9 are formed to ring shapes in center parts on both surfaces in an inside peripheral edge part 3 and an outside peripheral edge part 4 of a spacer 6. After substrates 1 and 1' are fixed on a base 10 with the spacer 6 between these substrates, a horn 11 of an ultrasonic welding machine is pressed from above to apply a pressure. Ultrasonic waves are generated in this state, and then, heat of friction is concentrated on projections 8 and 9 formed on the spacer 6 to fuse prohections 8 and 9, and disc substrates 1 and 1' and the spacer 6 are joined. Since the thickness of the weld- joint part and the joint area can be controlled freely by increasing or reducing sizes of projections 8 and 9 and the amplitude and the pressure of the horn 11, the joint layer is formed with a uniform thickness without variance of adhesion.
