摘要： A slide member has a sliding surface made of ceramic and a has surface roughness of not more than 1.0 .mu.m in center line average roughness Ra. The ceramics includes a silicon nitride sintered body which contains crystal grains having a linear density of at least 35 per 30 .mu.m in length with a boundary phase volume ratio of not more than 15 volume %, and which contains pores of not more than 20 .mu.m in maximum diameter in a content of not more than 3%. In a method of manufacturing the slide member, it is possible to ensure smoothness of the sliding surface by grinding the sliding surface and thereafter heating the ceramic in an either an inert gas or atmospheric air. A slide member that can be used under severe sliding conditions of high-speed sliding or the like and that has excellent wear resistance is obtained. Even if the slide member is used for to a sliding part of a compressor or the like which employs a fluorocarbon containing no chlorine as a cooling medium, it is possible to prevent the occurrence of seizure and abnormal wear on the sliding surface.

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.

摘要： The present invention relates to improvement of a quadrupole electrode for use in a mass spectrometer or the like, in which two pairs of electrode rods 1, 2, 3 and 4 formed in such a manner that the section of the opposed face of each rod is hyperbolic or circular, and each electrode rod is made of a ceramic and the surface of the electrode is coated with a coating layer 5 of a conductive metal. Further, the present invention relates to a production process, characterized by incorporating such four electrodes at predetermined intervals. Since the electrodes are mainly made of a ceramic which is easily formable with a high dimensional accuracy, the adjustment of the positional relationship between the electrodes during assembling can be made without much effort, which enables a quadrupole electrode having a high performance to be provided with a good reproducibility at a low cost.
