Granted: 1999-10-01
Abstract: To facilitate the processing of an electrode, and prevent the drop of capacitance by constituting a capacitor lower electrode of a metallic electrode consisting of iridium or ruthenium, and preventing oxidation of the lower electrode from occurring in formation of a capacitor dielectric film. A capacitor lower electrode is constituted of a metallic electrode. And, as the material of the metallic electrode, ruthenium or iridium is used in place of platinum, and the thickness of the metallic electrode is made 30-600 nm. Hereby, the surface of the oxide is not oxidized at the time of formation of a capacitor dielectric film, and the structure of a cell becomes simple, and besides, stable capacitor property can be obtained. Moreover, as compared with the prior art case where platinum is used as an electrode material, the processing of the electrode becomes easy.

Title: Long product rolling mill
Inventor: NAKAYA MASAMITSU
IPC: B21B31/18
Filed: 1998-01-09
Granted: 2001-07-21
Abstract: The caliber change for a working roll 8 having a plurality of calibers C1, C2 on its outer peripheral surface has heretofore involved the operation of removing the working roll 8 from the tip of a roll supporting shaft on a pass line P. This operation requires a long time, thus resulting in deterioration of productivity. A roll housing 7 capable of shifting in the axial direction of the working roll 8 is provided separately from a bevel gear box 6, and the caliber change is performed by shifting the housing 7. For absorbing a change in axial length of a driving force transfer path with a shifting motion of the housing 7, an axially protrudable/retractable means such as a spline shaft 25 is provided in the said path. Since it is not necessary to remove the working roll 8 at the time of caliber change, the caliber changing work becomes easier and the time required is shortened, so that the productivity is improved.
