  • Publication number: 20220390294
    Abstract: A method for measuring interfacial stress and residual stress in multilayer thin films coated on a substrate is disclosed. First of all, a residual stress measurement process is applied to each thin film of a multi-layered structure. Subsequently, after two kinds of interfacial stress (FHL, FLH) are calculated, a mathematical formula for estimating at least one adjusting parameter is derived based on the two interfacial stresses. As a result, a modified Ennos formula is obtained by involving the adjusting parameters into the Ennos formula, such that a residual stress in the multi-layered structure (i.e., multilayer thin films) is therefore calculated by using the modified Ennos formula.

  • Patent number: 10258162
    Abstract: A foldable chair includes a chair body having two rear legs, a metal seat movable upward and foldable on the rear legs so as to occupy little storage room. When the seat is moved to a seated position and when the rear legs are moved to a stretch-out position, the seat has a bottom edge seated on the top end of the rear legs and defines a straight line aligned with a middle line of the top end of the rear leg. An integrally formed strengthening structure extends across a bottom side of the seat so that gravity center of the seat is concentrated on the top ends of the rear legs, thereby strengthening the supporting ability of the rear legs relative to the seat so that even sitting of an overweight person on the seat does not deform and damage the seat and the rear legs.
