Patent ID: 7487710

Claim:
A high-pressure generation apparatus, comprising: a pair of columnar-shaped anvils disposed in opposed relation to one another; a pressure-generating space defined between said anvils; said anvils being adapted to be applied with a load therebetween to generate a high pressure in said pressure-generating space, wherein each of said anvils has a top portion formed in an approximately circular truncated cone shape, said top portion having a central region formed with a depression having a side surface which extends obliquely outward; and a laminated member surrounding the pressure-generating space and formed with a least two metallic thin plates and a plurality of insulating gaskets that are placed between the metallic thin plates and between the metallic thin plates and the anvils; wherein the high-pressure generation apparatus produces a pressure in the pressure-generating space of approximately more than 60,000 atmospheres to approximately at least 100,000 atmospheres.
