Patent attributes
Disclosed is a high-pressure generation apparatus, which comprises a pair of columnar-shaped anvils disposed in opposed relation to one another to define a pressure-generating space therebetween. The anvils are adapted to be applied with a load therebetween to generate a high pressure in the pressure-generating space. Each of the anvils has a top portion formed in an approximately circular truncated cone shape, and the top portion has a central region formed with a depression having a side surface which extends obliquely outward. The high-pressure generation apparatus also includes a cylindrical capsule disposed in a central area of the pressure-generating space, and a laminated member formed by alternately laminating a doughnut-shaped metallic thin plate and a doughnut-shaped insulating member along the outer periphery of the capsule. The improved shape of the depression makes it possible to significantly reduce damages of the components. In addition, the laminated member formed of the metallic thin plate and the insulating member originally used for sealing the pressure-generating space makes it possible to generate a higher pressure.
