A mechanical seal 4 is a static pressure type non-contact gas seal, including a rotary sealing ring 5 that is fixed to a rotating shaft, and a stationary sealing ring 7 that is engaged and held in an inner periphery of a seal case 6 made of a metal by means of O-rings 12 so as to move in an axial direction thereof. The O-rings 12 are held engaging with the outer periphery of the stationary sealing ring 7, and come in press contact with the inner periphery of the seal case 6 so as to give a secondary seal to a gap between the stationary sealing ring 7 and the seal case 6, while allowing the stationary sealing ring 7 to move ih ng a thickness in the range of 5 to 100 μm is formed on the inner periphery of the seal case 6 at least within a range in which the O-rings 12 relatively move in accordance with the movement of the stationary sealing ring 7 in the axial direction.

An electrostatic charge image developing toner includes toner particles that contain a binder resin having a carboxyl group, in which the carboxyl group in the binder resin present on the surfaces of the toner particles forms an alkaline earth metal salt, and an amount of the alkaline earth metal which is detected through ion chromatography of the toner particles is in a range of from 1.00×10−10 mol/g to 0.90×10−6 mol/g.
摘要:
A shaft-seal device for high-temperature fluid including a seal case (2) formed as a metallic cylindrical structure of a single unit and comprised of a main body portion (2a, 2b, 2c), first and second holding portions (2d, 2e), first and second partition portions (2f, 2h), a channel formation portion (2g) forming a minute annular channel (27) with the outer circumference surface of a rotary shaft (1), and an o-ring holding portion (2i). The seal case is installed in an apparatus housing (8) with first and second o-rings (2m, 2n) in between. The intra-seal case region (A1), in which sealing rings (31, 32, 41, 42, 51, 52) of mechanical seals (3, 4, 5) are provided, and the high-temperature fluid region, which is an intra-apparatus housing region (A), are partitioned by a cooling chamber (28) into and from which coolant (82) is supplied and discharged via feed/discharge coolant paths (80, 81).
摘要:
A toner set for electrostatic image development, includes: at least one kind of a colored toner that contains a coloring agent; and a transparent toner that does not substantially contain a coloring agent, wherein a proportion of particles having a shape factor of 0.94 or less in mother particles of the transparent toner is about 5% by number or less based on particles having a particle diameter of 7.5 to 15 μm, and a reflectance of the mother particles of the transparent toner is about 90% or more for light at a wavelength of 700 nm.
摘要:
A mechanical non-contact gas seal including a rotary scaling ring and a stationary sealing ring that is engaged and held in an inner periphery of a seal case by means of O-rings so as to move in an axial direction thereof. The O-rings engage with the outer periphery of the stationary sealing ring and come in press contact with the inner periphery of the seal case to seal a gap between the stationary sealing ring and the seal case while allowing the stationary sealing ring to move in an axial direction. A resin coating of a thickness in the range of 5 to 100 μm is formed on the inner periphery of the seal case at least within a range in which the O-rings relatively move with the movement of the stationary sealing ring.
摘要:
An electrostatic latent image developing dry toner and the like are provided, in which toner remaining after transfer can be recovered during developing with or without having a blade cleaning stage for promoting friction of an electrostatic latent image holding member. The electrostatic latent image developing toner contains toner particles containing a binder resin and a colorant and monodisperse resin particles having a volume mean diameter of 80 to 300 nm, a gel ratio of 60% or more by weight, and a standard deviation of D50×0.20 or less. A method of producing the above toner first mixes monodisperse resin particles, which have a volume mean diameter of 80 to 300 nm, a gel ratio of 60% or more by weight, and a standard deviation of D50×0.20 or less, with toner particles containing a binder resin and a colorant, and adds an inorganic compound having a diameter smaller than that of the resin particles with a shear lower than the first mixing.
