摘要： A connection structure between lead frames and a base plate of aluminum nitride, to be applied as a connection structure between components of a semiconductor apparatus, has a base plate made of a sintered body of aluminum nitride on which a semiconductor device is to be mounted. The lead frames are made of iron alloy containing nickel in 29 wt. % and cobalt in 17 wt. %. A silver solder is used for joining the base plate and the lead frames. A surface of the lead frame to be joined to the base plate is clad with a stress relief layer of oxygen-free copper of a high plastic deformability to relieve, by its plastic deformation, a thermal stress caused by a difference between a thermal expansion coefficient of the aluminum nitride base plate and that of the lead frame in a cooling process at the time of soldering. Preferably, only a portion of each lead frame to be joined to the base plate comprises an inner layer of an iron alloy containing 29 wt. % of nickel and 17 wt. % of cobalt, and an outer layer portion of oxygen-free copper.

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： To provide sliding components each comprising a base metal and, joined thereto, a sliding face member having a sliding face of crowning profile, in particular, sliding components such as valve train parts, a cam follower and a rocker arm of an automobile engine. A sliding component having a structure comprising (1) a ceramic forming a sliding face and (2) a base metal joined together, in which the extent of crowning of the sliding face is at least 0.1 to 0.4% of the maximum length of the junction face of the ceramic. The ceramic has a four-point flexural strength of at least 50 Kg/mm as measured in accordance with the Japanese Industrial Standard R1601. The base metal is mainly steel at least the surface of which has preferably a martensite texture and has a hardness of higher than 45 in terms of H.sub.RC. The structure may have an intermediate layer of a metal or cermet. In one mode the junction of the sliding face member such as a ceramic of crowning profile is simultaneously carried out with the formation of the base metal part and in another mode the sliding face of the base metal is hardened by the heating after the junction. A sliding component whose extent of crowning is great can be provided at a lowered cost without suffering from defects such as cracking.

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.
