Filed: 1990-02-02
Abstract: PURPOSE:To keep initial function worked for a long time by forming hardened films on sliding faces of a guide part of a moving side flange, as well as of the guide part of an electrifying shaft. CONSTITUTION:Films 25, 26 are formed on sliding parts of a guide part 22a of a moving side flange 22 as well as of a moving side electrifying shaft 15. The electrifying shaft 15 is directly guided by the guide part 22a of the flange 22, and is positioned thereby, and assembly is thus facilitated with a small number of components. In addition, since the co-axial assembly to the flange 22 is achieved with good accuracy, concentricity with a fixed side electrifying shaft is improved, and electrifying, arc-extinguishing, and voltage withstanding features are also improved. The films 25, 26 are highly hardened, and the abrasion of the sliding part due to the vertical movement of the electrifying shaft 15 can be reduced. Even when the opening/closing becomes more frequent, initial electrifying, arc-extinguishing, and voltage withstanding characteristics can be exhibited.

Title: Pressure fixing device
Inventor: YAMASHITA KEITAROU
IPC: G03G15/20
Filed: 1979-02-27
Abstract: PURPOSE: To improve the pressure distribution of rolls and prevent the creasing of paper by constituting the top roll and bottom roll with the point of intersection of their respective central axes being deviated from the center of the rolls.  
     CONSTITUTION: The centerlines of the respective rolls of a top roll 1, bottom roll 2 and backup roll 3 are crossed in the positions deviated from the center of the roll length. Namely, in the central position, the centerline of the bottom roll 2 is in the position deviated from the perpendicular line on which the centerlines of the top roll 1 and backup roll 3 are placed. As for the deviation of the crossing point of the centerlines of the rolls from the center, suitably selecting the same from roll sizes and fixing pressures suffices. However, in ordinary cases, with the deviation up to 10mm, the prevention of paper crease cannot be done and above 60mm, the pressure drop of the pressure distribution ends becomes excessive, causing fixing failure. Therefore, between 10W60mm are preferable. In this way, the pressure distribution of the rolls may be improved and the creasing of paper prevented.

Abstract: PROBLEM TO BE SOLVED: To improve the radiation characteristic of a condenser and to save the energy by providing a heat exchanging pipe comprising a thermo-siphon to which a pair of opening parts are faced in a gas-liquid two-phase region on the downstream side of the condenser in the refrigerating cycle to suppress the dryout phenomenon. SOLUTION: In the refrigerating cycle, a condensation-proof pipe 3c comprises a thermo-siphon of open-loop type, and a pair of opening parts are provided so as to opposite to the gas-liquid two-phase region on the downstream side of a condenser.
