Abstract: Antistatic agents, adhesives and coatings with high antistatic properties under low humidity and temperature, which contain a quaternary ammonium salt of formula I: ##STR1## wherein each of R.sub.1, R.sub.2 and R.sub.3 is an alkyl radical having 1-5 carbon atoms, and R.sub.4 is an alkyl radical having 1-3 carbon atoms.

Abstract: A recording/printing unit using roll paper, and method for easily and securely detecting the terminal end of roll paper rolled around a core inside a color printer. The outside face of said core is darker than the roll paper. A sensor is provided for detecting the intensity of reflected light. A pinch roller is provided turning in contact with the roll paper surface and a spring is provided for pressing the pinch roller against the surface of roll paper, and for detecting the terminal end of roll paper by the change in the intensity of reflected light.

Abstract: A paper guide printer with simple structure, high positioning accuracy and color print of excellent picture quality. The printer/recording unit includes a platen roller, a roll type recording paper which is pulled and fed on the platen roller and a recording head. A recording paper pull-feed mechanism is installed which includes a clamp opening closing unit for catching the end of the roll type recording paper and for making the linear reciprocation movement by the designated cycles at every recording in accordance with the length of main run direction being recorded at one time, and also the roll paper drum that can be turned in reverse direction for pulling back the recording paper when the roll type recording paper reciprocates at the designated cycles.

Abstract: The present invention is a bonding anchor coating agent and a laminated film having an anchor coating layer which provides a high anti-static performance on a film surface without having to mix the anti-static agent into the basic material of the film. The bonding anchor coating agent contains polyethylene imine and a bridge formation polymer having the ability to prevent electrostatic induction. The laminated film contains the anchor coating agent in the basic material of the film.
