71 units), it was not easy to attach or detach it from the LI/P furnace.
（２）支持台からの熱放散が大きかった。(2) Heat dissipation from the support was large.
（３）支持台の上部と下部で温度差が生じ、この温度差
のために熱歪（亀裂）が発生した（支持台耐久ｒσ低下
）。(3) A temperature difference occurred between the upper and lower parts of the support, and thermal strain (cracks) occurred due to this temperature difference (reduction in durability rσ of the support).
（４）上記（３）の亀裂からカスリークが生じ使用不能
になった。(4) A gas leak occurred from the crack in (3) above, making it unusable.
