An image forming apparatus, which appropriately performs a banding correction even if similar banding does not always occur at a same position of a recording medium, detects reflected light from a test patch image and obtains information on a density change caused by a periodically-uneven rotation of a rotation member, and performs a density correction at an arbitrary position of a print image based on the acquired information on the density change.
摘要:
A thermoplastic resin foam which has both high reflectance and superior shape-retention properties, suitable for use in backlights and illumination boxes for illumination signboards, lighting fixtures, displays and the like. The thermoplastic resin foam is manufactured by a manufacturing method including a procedure for holding a resin sheet composed of thermoplastic resin (A) and thermoplastic resin (B), which has a functional group having an affinity with thermoplastic resin (A), within a pressurized inert gas atmosphere to enable the resin sheet to contain inert gas, and a procedure for foaming by heating the resin sheet containing inert gas at a temperature higher than the softening temperature of thermoplastic resin, under normal pressure.

摘要:
Provided is a double-side coating apparatus which can uniformly coat both surfaces of a substrate to be processed with a coating solution and form uniform coating films on both the surfaces of the substrate to be processed. A double-side coating apparatus (1) includes a holding mechanism (3a) which holds a substrate (2) to be processed so that the thickness direction of the substrate (2) to be processed is a horizontal direction; a rotational driving mechanism which rotates the substrate (2) to be processed in a circumferential direction; a first coating solution nozzle (18a) which jets a coating solution onto one main surface (2a) of the substrate (2) to be processed; and a second coating solution nozzle which jets the coating solution onto the other main surface (2b) of the substrate (2) to be processed. The first coating solution nozzle (18a) and the second coating solution nozzle are symmetrically arranged with respect to a thickness center surface of the substrate (2) to be processed. Provided is an edge rinsing apparatus which can accurately and stably rinse only a fixed width of an outer peripheral portion of the substrate and can easily control the width of the outer peripheral portion to be rinsed even if the width of the outer peripheral portion to be rinsed is small.
