    摘要: A ball-point pen having a coupling, a tip at the distal end of the coupling, and a reservoir tube at the proximal end of the coupling. The tip may held in a tip holder, which, in turn, is coupled to the distal end of the coupling. A valve chamber is formed within the coupling with a ball seat having a guide hole therethrough on the rear portion of the valve chamber and projecting ridges on the front portion of the valve chamber. When the ball-point pen is positioned with its tip upward, a ball valve is brought into contact with the ball seat to close the guide hole and thereby prevent back flow of ink. When the ball-point pen is positioned with its tip downward, the guide hole is opened and the ball valve contacts the rear ends of the projecting ridges, so that ink flows into the tip through the guide hole, the valve chamber, and grooves formed between the ridges. A spring may be interposed in the inner hole of the tip with its proximal end held in place by the coupling. The distal end of the spring presses a writing point ball into contact with the ball-holding portion of the tip. A low-viscosity ink or an ink having shear thinning properties, i.e., statically a high viscosity which is decreased upon rotation of the ball during writing, is preferably used.

    摘要: A cleaning blade and process for use in an image forming apparatus wherein the blade removes residual developer from a photosensitive member. The cleaning blade can be in close contact with the photosensitive member. The blade extends substantially at right angles to the direction in which the photosensitive member moves. It has a lubricant layer formed on both end portions in the longitudinal direction of the blade, which forms part of a surface contacting the photosensitive member.

    摘要: The additive for a polymerizable composition according to the present invention contains a compound represented by the general formula (a). In the general formula (a), R represents a saturated hydrocarbon group having 1 to 3 carbon atoms. M represents Sn, Sb, Bi, or Ge. m represents 0 or 1. R and M are not directly bonded when m is 0. n represents an integer of 1 to 3. X represents a monovalent linking group, and a plurality of X may be the same as or different from each other. When two or more linking groups X are bonded with the metal atom M, the linking groups X may combine together to form a ring.
