Stress and deformation of cathode ray tubes (CRTs) under atmospheric pressure and implosion protection band tightening were analyzed using a finite element method (FEM). The stress and deformation of the tubes were measured experimentally by using st

It is well known that the strength characteristics of the glass used for the cathode ray tubes usually has a distinct scatter under the influence of surface flaws. Therefore, it is important to consider the variations in the static and delayed fractu

The delamination arrest between die pad and resin should be an efficient method to prevent resin cracking of LSI packages. In some LSI packages, dimples arranged on the die pad are effective for delamination arrest. In this study, the effects of dimp

This paper describes the fatigue life estimation of the welded joint having an unpenetrated portion in the pressure vessel by use of the fracture mechanics. The internal pressure fatigue tests of the pressure vessel were carried out at room temperatu

The arrest of delamination between the die pad and the resin is expected to be an efficient method to prevent resin cracking of LSI packages. In some LSI packages, dimples properly arranged on the die pad surface prove to be efficient for the arrest
