Abstract:
PROBLEM TO BE SOLVED: To provide a lubricant for electrophotography by which the amount of toner passing through a cleaning blade and remaining in a photoreceptor is reduced so as to be less than the conventional one regardless of the condition of the formed image even by using the toner formed into a spherical shape. SOLUTION: The lubricant for the electrophotography to be coated on a latent image carrier to which the toner having ≥0.94 spherical degree is fed, is obtained by adding an inorganic additive satisfying the relation of 2Y/1,000≤X≤Y/10 [wherein, Y is a particle diameter (μm) of the toner; and X is a particle diameter (μm) of the inorganic additive] thereto.

Abstract:
The invention concerns a threaded portion of a tubular element for a threaded tubular connection hiving an axis of revolution, the portion comprising a threading extending over its outer or inner peripheral surface, and a first sealing surface on the peripheral surface, the first sealing surface being capable of producing metal-metal interference with a corresponding second sealing surface belonging to a complementary threaded portion of a tube. The threading and the first sealing surface are coated with a metallic anti-corrosion and anti-galling layer wherein zinc (Zn) is tie major element by weight.
Abstract:
L'invention porte sur une fixation (10; 40) métallique pour assembler avec interférence au moins deux éléments de structure (20, 22) comprenant un perçage traversant, la fixation comportant une tête élargie (12; 42), un fût (14; 44) présentant avant installation un diamètre extérieur (D 1 ) supérieur à un diamètre intérieur (D 3 ) de l'alésage, ledit fût (14; 44) comprenant une surface conductrice (26; 56). Avant installation, au moins la surface conductrice (26; 56) est recouverte d'une couche (30) lubrifiante présentant une adhérence suffisante pour empêcher son abrasion par manipulation manuelle de la fixation (10; 40) et suffisamment faible pour être arrachée de la surface conductrice (26; 56) au moins partiellement lors du montage en interférence de la fixation (10; 40), un mélange d'au moins une polyoléfine et d'un polytétrafluoroéthylène par exemple. L'invention concerne également un procédé d'obtention d'une telle fixation (10;40) et un procédé d'installation d'une telle fixation (10; 40) dans une structure (22; 24). L'invention s'applique à l'assemblage de structures d'aéronefs.
Abstract:
Lubrication and friction reduction improves fuel efficiency and reduces energy consumption. Effective and controllable material removal results in superior surface finishing and planarization. Nanosheets are developed with specific functionalization that can be used to reduce friction and wear, improve the fluidic property, and rheological performance.. The nanosheets can be from the graphite family, transition metal dichalcogenides, transition metal trichalcogenides, semiconducting chalcogenides, metal oxides, layered hydroxides, clays, ternary transition metal carbides and nitrides, and zirconium phosphates and phosphonates, and their corresponding dopants. Tribological, rheological, and polishing applications include lubricants, viscosity modification, and chemical-mechanical planarization. The nanosheets are useful in improving efficiency and lifetime of machinery, saving energy for mechanical operations, and optimizing manufacturing processes in surface engineering.
