摘要:
A new austenitic stainless steel containing approximately 0.1-1.0 mass % of Si and not more than approximately 0.003 mass % of Al. Nonmetallic inclusions dispersed in a steel matrix are converted to MnO—SiO2—Al2O3 containing not less than approximately 15 mass % of SiO2 and not more than approximately 40 mass % of Al2O3. During steel making, molten steel is covered with basic slag and heavily deoxidized with a Si alloy whose Al content is controlled to not more than approximately 1.0 mass % in a vacuum or non-oxidizing atmosphere. The austenitic stainless steel sheet can be formed to an objective shape without the occurrence of cracking due to its decrease in susceptibility to cracking and its good formability.

摘要:
It is made possible to reduce the interface resistance at the interface between the nickel silicide film and the silicon. A semiconductor manufacturing method includes: forming an impurity region on a silicon substrate, with impurities being introduced into the impurity region; depositing a Ni layer so as to cover the impurity region; changing the surface of the impurity region into a NiSi2 layer through annealing; forming a Ni layer on the NiSi2 layer; and silicidating the NiSi2 layer through annealing.

A switch element includes a substrate; a plurality of carbon nanotubes provided upright on the substrate; magnetic particles arranged at tip ends of the carbon nanotubes respectively; and a plurality of conductive layers formed between base ends of the carbon nanotubes and the substrate. A switching operation of the switching element is performed in such a manner that the carbon nanotubes or the magnetic particles are brought into contact with each other according to an electrical potential between the conductive layers, and the carbon nanotubes are separated from each other when an electrical current flows through the carbon nanotubes with the carbon nanotubes or the magnetic particles brought into contact with each other.

Disclosed is a mayonnaise base which is mixed with eggs by consumers to give mayonnaise. The mayonnaise base consists indispensably of vegetable oil, vinegar and emulsifier (except egg yolk) along with other seasonings (except vinegar) and spices, and is stored in an oxygen-free container. The mayonnaise base is mixed with fresh eggs by consumers to give mayonnaise with ease. In accordance with the consumers' request, either whole eggs or only egg yolk or albumen can be added to the mayonnaise base.
摘要:
In a case for holding and carrying a substrate such as a photomask, a case body comprises a top cover and a bottom cover, whose inner surfaces include inwardly extending protrusions integrally formed therewith. The protrusions are crowned with silicone caps to hold a substrate. The substrate within the case is at its four corners fixedly held from both sides by the silicone caps. The top and bottom covers also include at their inner surfaces a plurality of positioning projections designed to come into contact with the edges of the substrate to place the substrate in position in its surface direction. Then the top cover and the bottom cover are brought into engagement with each other and fastened together, thereby providing a case low in dust generating characteristics arising from vibration and capable of holding various sizes and thicknesses of the substrate.

摘要:
A twin-roll type continuous casting apparatus comprises a pair of rotatable drums and a pair of side dams disposed on both axial ends of the drums so that a pool of molten steel is defined by the drums and the side dams. As the drums are rotated in counter directions, the molten steel is cooled so that the molten steel is partially solidified to form solidification shells which are then pressure-bonded to each other as they pass through the narrowest gap defined between the drums, so that a steel sheet is formed by continuous casting. The side dam is composed of a side refractory part which functions to maintain the pool of molten steel and a metallic member which supports the side refractory part and which serves as a cooling plate for cooling the steel. The side refractory part is projected inwardly of the pool from the metallic member and arranged so that the lower end thereof is positioned in the vicinity of a point where the pressure-bonding of the solidification shells is commenced, the point being located above the narrowest gap defined between the drums.
