Abstract: The quantitatively and objectively present invention provides an apparatus for evaluating the contact pressure distribution in a temporomandibular joint. Specifically, the mandible and cranium are converted to two-dimensional rigid body element models by use of positional data of their contact line acquired from an image input device to compose a rigid body spring model, where only vertical springs resisting in vertical direction to the contact line are assumed in temporomandibular joint portion and vertical springs resisting in vertical direction as well as shear spring resisting in the direction parallel to the contact line are assumed in the teeth portion. An external force converted from an assumed elevation myodynamia is exerted on this model, and based on the theory of a rigid body spring model, stresses at each of the springs are calculated to represent contact pressures due to reaction forces against the external force mentioned above.

Abstract: An object, such as a container cover, is lined on a predefined area of the object by depositing powder on the predefined area. The lining material is formed into a non-spherical powder having a resting angle of 40 degrees or greater. The powder is deposited by fluidizing the powder in a feeder using vibration and conveying the powder through a nozzle to the predefined area. The powder layer deposited on the object is pressed with a molding element to form a lining layer having the predefined shape. The lining thus formed has a predefined thickness distribution and shape with good tightening and sealing properties and corrosion resistance. In addition, no environmentally unsafe processes are required for the precise deposition of powder.
