摘要： PROBLEM TO BE SOLVED: To control the lubricated condition of the friction surfaces in between of two frictional members. SOLUTION: An insulating material layer 15 and a sliding material layer are laminated on a movable electrode 14, while an insulating material layer 13 and a porous sinter layer 11 to slide with the sliding material layer 16 are laminated on a stationary electrode 12. The porous sinter layer 11 has open pores 11c leading from the sliding surface 11a to the other surface, and the pores 11c contain lubricating oil which can form electric double layer at the interface with the porous sinter layer 11. When an electric field is impressed between the stationary electrode 12 and movable electrode 14 positioned opposing, the lubricating oil in the pores 11c makes movement owing to the electroendosmosis in the direction decided by the ζ-potential (potential difference between inside the oil and the sliding surface).

摘要： PURPOSE:To prevent any abnormal wear in a contact part between a roller and a vane, in this rotary compressor. CONSTITUTION:A turning shaft 26 has a decentered crank part 28, rotating a roller 38 eccentrically in a cylinder 32. A vane 140 slides in a groove installed in this cylinder 32 and comes into contact with a peripheral surface of the roller 38, forming a pressure chamber there, supporsing a turning angle of the roller 38 at a time when the vane is in a position starting its reciprocation is set to zero, a turning angle of the roller is somewhere about 90 to 270 degrees and thereby pressing force of the vane 140 against the roller 38 becomes maximized. At this time, a contact surface 140b of the vane 140 in contact with the roller is formed into a small surface or flat surface being small in curvature, while such a vane material as being lower in elastic modulus than a roller material and further high in self-lubricity is used. With this constitution, a Hertzian stress in a contact part between the vane and the roller is reducible, and also any abnormal wear in a roller outer diameter is preventable.

摘要： PURPOSE:To effectively utilize sputtered particles to form a thin film by irradiating a target material with an energy beam while moving the irradiation position. CONSTITUTION:The ions of Ar, etc., are drawn out by a focusing electrode 6, focused by an Einzel lens formed along with an ion beam deflecting electrode 4 and a source gas supply plate 8 and introduced to a sputtering region. A periodical voltage is impressed on the electrode 4, and the beam is deflected, rotated and scanned. Furthermore, the beam is modulated in a serrated form with a slow cycle, and the focused point of the beam is scanned over the whole region of a condensed source 13 in its axial direction. The inner surface of a condensed target 1 is irradiated with the focused beam which is moved in its axial direction and draws a circle, and the condensed source 13 is also irradiated. The sputtered surface is cooled until the beam comes next time, and a fresh source gas is condensed. The sputtered particles are deposited on a sample substrate 10 to form a thin film.

摘要： PROBLEM TO BE SOLVED: To improve startability of a lubricating sliding part whose sliding surface may be cleaned by solvent by reducing a mean diameter of open air holes on a surface or near the surface, and forming an open air hole which can possibly hold lubricating oil of large volume. SOLUTION: At least one of sliding members has a minute air hole 2 to the outside, that is, an open air-hole 2 whose surface diameter ranges between 1.5 to 5 micrometers on its surface 1 on the sliding side or near the surface 1. A large open air hole 4 is formed in an inside portion 3 communicated to the outside through the open air hole 2 on the surface 1 or near the surface 1, which hole 4 is larger than the surface 1. When lubricating oil on the sliding surface is cleaned by solvent such as coolant by capillarity of the minute hole 2 on the surface 1, the lubricating oil stored in the inner comparatively large open air hole 4 is fed to the surface 1 or suctioned thereto. Satisfactory lubricating condition can be attained at the time of starting.
