Geologic phenomena that characterize Japanese islands (e.g., volcanism, faulting and crustal deformation, metamorphism, and formation of ore deposits) are taking place within the crust (shallower than 30 km depth). Internally heated gas medium high-pressure apparatus (or hot isostatic press, HIP) would be the most important tool to study these geologic phenomena at crustal depths. Due to the rigorous regulation by law, HIP apparatuses have not been popular among Japaese earth scientists. Beyond SOOMPa range, only one operating HIP exists in a material research laboratory in Yamaguchi Prefecture. In this project, with KOBELCO Co. we have developed a new HIP (SMC-8500), which is capable to conduct experiments up to 85OMPa. The SMC-8500 has relatively large vessel size (65 mm diameter and 400mm long) with quenching device by cutting the hanging wire of the specimen at the termination of each experiment. The internal pressure of the SMC-8500 can be measured directly by a pressure gauge up to 200MPa. Beyond 200MPa the internal pressure can be estimated only through hydraulic pressure of the main piston. It was found that there is a large frictional loss (perhaps at the gas sealing part) between the hydraulic presssure and the internal gas pressure. We have tested that the internal gas pressure can be monitored by resistance change in a Manganin wire. Using the Manganin as an internal scale, the internal gas pressure of the SMC-8500 can be controlled by the hydraulic system.

日本岛屿特有的地质现象（例如火山活动、断层和地壳变形、变质作用和矿床形成）发生在地壳内（深度小于 30 公里）。内加热气体介质高压装置（或热等静压机，HIP）将是研究地壳深处这些地质现象的最重要工具。由于法律的严格规定，HIP装置并未受到日本地球科学家的青睐。在 SOOMPa 范围之外，山口县的材料研究实验室中仅存在一台正在运行的 HIP。在这个项目中，我们与KOBELCO Co.开发了一种新型HIP（SMC-8500），它能够进行高达85OMPa的实验。 SMC-8500具有相对较大的容器尺寸（直径65毫米，长400毫米），具有淬火装置，可在每次实验结束时切断试样的挂线。 SMC-8500的内部压力可以通过压力表直接测量，最高可达200​​MPa。超过200MPa时，只能通过主活塞的液压来估算内部压力。发现液压和内部气体压力之间存在很大的摩擦损失（可能在气密封部分）。我们已经测试，可以通过锰铜线的电阻变化来监测内部气压。使用锰铜作为内部秤，SMC-8500的内部气压可以由液压系统控制。
