Abstract: An inkjet printer with a nozzle plate that has an exterior surface with formations for reducing its co-efficient of static friction. By reducing the co-efficient of static friction, there is less likelihood that paper dust or other contaminants will clog the nozzles in the nozzle plate. Static friction, or “stiction” as it has become known, allows dust particles to “stick” to nozzle plates and thereby clog nozzles. By patterning the exterior of the nozzle plate with raised formations, dust particles can only contact the outer extremities of each formation. This reduces friction between the particles and the nozzle plate so that any particles that contact the plate are less likely to attach, and if they do attach, they are more likely to be removed by printhead maintenance cleaning cycles.

Abstract: The present invention surely absorbs ink leaked from an atmospheric pressure introducing port using an ink absorber while achieving the miniaturization of an ink jet recording apparatus. An ink absorber housing is constituted of a fixing plate and a frame body which is formed on a periphery of the fixing plate and accommodates an ink absorber therein. Projecting ridges which project toward the ink absorber side and are brought into contact with the ink absorber are formed on an inner surface of the frame body thus increasing a holding force for holding the ink absorber in the inside of the ink absorber housing. Since the projecting ridges are brought into contact with portions of the ink absorber and resiliently deform the ink absorber, the deformation occurs partially and a deformation quantity is small. Accordingly, it is possible to increase the holding force for holding the ink absorber while preventing the large crushing of the small pores and the small interstices among the fibers in the ink absorber.

Abstract: A novel latch for pivoted optical elements of a solar concentrator and other equipment latches them in position between orientation operations. The mirrors may be on a universal pivot that can rotate or tilt in any direction; or on gimbal pivots. The orientation power can be turned off between alignments with the mirrors remaining in alignment orientation during this off-power period.
