20210140472 · 2021-05-13 ·

Methods and apparatus for transporting a flexible substrate are provided. In one embodiment, an air turn is disclosed that includes a body, a porous cover disposed about a circumference of the body, and two seals. Each of the two seals are positioned about the circumference of the body and spaced apart from each other in a longitudinal direction of the body to define a central zone bounded by a second zone and by a third zone. The second zone and third zone are each positioned outside of a respective seal. The body includes a first opening formed along a longitudinal axis of the body, and a plurality of second openings formed in the body at a position other than along the longitudinal axis.

Fixing member, fixing device, and electrophotographic image forming apparatus

Provided is a fixing member including a base layer, and a surface layer on an outer surface of the base layer directly or with a primer layer interposed between the base layer and the surface layer, in which the surface layer is constituted by a single layer, the surface layer contains a fluororesin, and fluorine oil having a perfluoropolyether structure, and as for a measurement sample taken from the surface layer, when subjecting to predetermined treatments (i) and (ii), masses of an adhered material adhered in a unit area of a detection surface of a QCM sensor and containing the fluorine oil are within specific ranges.

VACUUM-SEALING DEVICE AND VACUUM CHAMBER DEVICE

A vacuum-sealing device includes: a first roll; a second roll that contacts the first roll; a first holding member having a first space in which the first roll is held and which has an axis coincident with an axis of the first roll; and a second holding member having a second space in which the second roll is held and which has an axis coincident with an axis of the second roll. The first holding member has an inner circumferential surface that faces the outer circumferential surface of the first roll, and rotation of the first roll and the second roll in correspondence with each other causes a sheet material to pass.
