    摘要： This invention aims at providing a sliding component having a crowning shape formed by applying surface quenching treatment to a portion made of a steel, and a production method thereof. The shape and the quantity of crowning can be controlled by heat-treatment or machining after the surface quenching. The sliding component may be made of a steel alone, or may be formed in such a manner that at least one portion of members forming the crowning-shaped sliding face by the surface quenching is joined or fitted to a sliding component main body made of the steel, and its material is a ceramic.

    摘要： The present invention is intended to provide a sliding member that can prevent abnormal wear and partial wear of the mating metal sliding component even when an oil contaminated with exhaust gas components is used. A ceramic sliding component is manufactured as followed. A silicon nitride-based material for the sliding face member is joined to a metal body having a higher thermal expansion coefficient than the sliding face member. A crowned portion is formed on the sliding face of the sliding face member in such a way that the difference between the amounts of crowning (da, db) at two arbitrary points axially symmetric with respect to the center line of the crowned portion is 10% or more and 50% or less of the average of the crowning amounts at the two points.

    摘要： The invention reduces the time required for nitriding in the process of reaction sintering for production of a sintered body of silicon nitride, thereby improving productivity, and provides a sintered body of silicon nitride having sufficient compactness and high strength which can be produced by reaction sintering. The sintered body is Si.sub.3 N.sub.4 having an unpaired electron density of 10.sup.15 /cm.sup.3 to 10.sup.21 /cm.sup.3. The sintered body is produced through reaction sintering by using a Si powder having an unpaired electron density of 10.sup.15 -10.sup.20 /cm.sup.3, which is obtained by annealing a commercially available Si powder at temperatures of 300.degree. to 800.degree. C. in other than nitrogen atmosphere for 3-5 hours. In particular, the sintered body is produced by adding to the so obtained Si powder, together with a sintering assistant, an element having a valence of, particularly, from +1 to +3, the element having a covalent bond radius RM which bears such a relation with the covalent bond radius RSi of Si that (RM - RSi)/RSi

    摘要： A vacuum vessel is provided in which the majority of a vessel wall including an annular wall portion (1) and a plate-wall portion (2) is formed of ceramic material such as silicon nitride, for example. To bond the plural wall members together, bonding faces having a surface flatness of not more than 1 .mu.m are prepared thereon, and then a ceramic powder bonding substance with an average particle diameter of not more than 1 .mu.m is interposed between adjacent bonding faces and subjected to heating. Because the generation of gas, such as hydrogen, from the wall of the ceramic vessel is reduced, extremely high vacuum can be generated and maintained in the interior of the vacuum vessel. Also, because the wall of the vacuum vessel has a high permeability with respect to a magnetic field and an electric field, the vacuum vessel can be used as a vessel in a particle accelerator that allows the high precision control of charged particles therein by means of an electromagnetic field.
