The object is to provide a magnet roller whereby picture quality can be improved by raising the magnetic flux density of the specified magnetic pole and/or other magnetic poles, and wherein this magnetic pole pattern can be achieved with low cost. In a magnet roller (10) according to the invention that achieves this object, a plurality of magnet pieces (12, 14, 16, 18) are mounted at the periphery of a shaft (20) by joining at joining faces and peaks (32a, 34a, 36a, 38a) of magnetic poles (32, 3...

The present invention discloses a roller assembly of an in-line roller skate, the roller assembly comprising a roller frame and a plurality of roller wheels, of at least two different sizes, which are fastened pivotally with the roller frame, such that the roller assembly may rock forwards and backwards upon a surface.

The present disclosure provides a paint applicator which may be used to apply paint to corners, to junctions between adjacent walls, along window trim, along floor moldings, or other surface adjacent to the surface being painted, without smearing paint on the adjacent surface. Moreover, the present disclosure provides a paint applicator having a trim system that prevents the painter's hands from becoming covered with paint upon actuation of trim system.

The present invention provides a fixing roller capable of satisfying releasing ability and scratch resistance all together. The fixing roller comprises a core 16, a primer layer 18 applied on the periphery of the core 18, and a fluororesin top layer 20 applied on the periphery of the primer layer 18, wherein glass particles 24 are mixed into at least one of the primer layer 18 and the top layer 20.

An electrophotography roller incorporated in an image creating device by the electrophotography comprising a conductive shaft disposed along the center axis, a conductive elastic layer around the shaft, a surface layer on the conductive elastic layer formed concentrically. The JIS A hardness of the conductive elastic layer is 30.degree. or less. The shear modulus of the conductive elastic layer measured in viscoelasticity under the condition of 20.degree. C., 60% PH and 0.1 Hz is 4 10.sup.5 Pa o...

A roller cam with pairs of sliding surfaces and wear plates located in an upper plane and with pairs of laterally slanted sliding surfaces and pairs of laterally slanted guiding wear plates located in a lower plane. The guiding wear plates are longitudinally contained between end plates to avoid using screws, which might loosen under stress, to secure the wear plates. Adjusting setscrews are used to laterally adjust the guiding wear plates, and positive return members are used to provide a tool ...

A roller bearing includes an inner ring, an outer ring, a plurality of cylindrical rollers each provided between rolling contact surfaces of the inner ring and the outer ring. Each of the cylindrical rollers includes an end face having a peripheral part that is crowned. A flange portion is formed at an outer circumferential face end part of the inner ring and/or an inner circumferential face end part of the outer ring. The peripheral part is crowned in a curving shape represented by an exponenti...

A large micro-debris roller having one sided adhesive sheets facing outward and wound up on a rotatable core. The core is supported by a symmetrical handle. Each adhesive sheet is provided with a non-adhesive tab which cooperates with perforations in the adhesive sheets to make possible the simple disposal of the adhesive sheets.

The invention relates to a roller mill, particularly a modular air-swept mill, with a rotary grinding pan on which roll grinding rollers and having columns, on which are mounted by means of rockers the grinding rollers, the columns being in each case fixed to a foundation frame and arranged as a mill foundation frame. For the use of stable and torsionally stiff columns for relatively large roller mills, according to the invention the foundation frames of the columns, together with the connecting...

A paint roller (10) has a paint applicator (12), two holder mounts an applicator holder (14). The paint applicator (12) has a cylindrical outer surface and two opposite ends (18a,18b). The two holder mounts, respectively associated with the two opposite ends (18a, 18b), each has a base surface (24) and a journal (26) that protrudes from the surface (24) away from the paint applicator (12). The applicator holder (14) has a handle (40) and a fork (42) with opposite sides (44,48) that each has a jo...
