摘要： An objective of the present invention is to provide a switching device that shows two markedly different stable resistance characteristics reversibly and repetitively, and which is applicable to highly integrated nonvolatile memories.The present invention provides a switching device, which comprises a variable resistor element that has, between two electrodes, a metal-oxide thin-film comprising a single central metal element with a compositional variation; which is connected to a control circuit which can apply, between said two electrodes, a voltage or a current selected from among a voltage or a current of the first threshold or higher, a voltage or a current of the second threshold or lower whose absolute value is smaller than the absolute value of said first threshold, and a voltage or a current of the third threshold or lower whose absolute value is smaller than the absolute value of said second threshold; and in which the interelectrode resistance characteristic reversibly changes by a factor of 1,000 to 10,000 in the voltage or current region whose absolute value is equal to or below the third threshold.

摘要： 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.
