Filed: 1992-12-03
Abstract: PURPOSE: To prolong the life of a spot welding electrode by forming a weldable primer film on a zinc-coated metal substrate and forming a specified amount of protective film per unit area on it. CONSTITUTION: A primer film composition is one-layer-coated on the surface of a zinc-plated metal substrate and is dried by heating to form a primer film. A protective film composition of an amount sufficient to form about 50-400 mg/ft<2> by dry weight of film is coated on the primer film and is dried by heating to form a protective film. The primer film composition contains binder, solvent and about 50-60 wt.% ferrophosphorus as a conductive pigment, and the ratio of pigment/binder is about 3:1 to about 5:1. The life of a copper-tipped spot welding electrode is prolonged to 200 times or more in the number of times of welding.

Abstract: PURPOSE:To always obtain an image with high quality by forming a prescribed- shaped electrostatic latent image at a part other than the original image forming area of a latent image carrier when the size of a specified area is equal to or under the size of an image area which is previously set. CONSTITUTION:A comparison circuit which compares the size S of the area specified for an original image which is calculated by an arithmetic part 22 with a reference size value So which is previously set and a count circuit being as a count means for the number of copied sheets are provided in a toner concentration control circuit. Then, when the original image whose size S specified by an original pressing plate 1 is smaller than the reference value So is consecutively copied equal to or above the prescribed number of copied sheets (np), solid developing is executed at P in a figure. Due to that, Vb (toner concentration voltage) < Vc (toner reference voltage) is attained before the electrostatic charge quantity of toner is over Qmax. Then, the new toner is replenished. Thus, the change of the electrostatic charge quantity of the toner is always controlled within a proper range, that means, between Qmin or more and Qmax or under. As the result, the image with the high quality is obtained.

Filed: 1987-12-24
Abstract: PURPOSE:To make a press plate with a high plate wear in an easy and simple manner, by using an adhesion chemically applied to an ink to selectively make the ink adhere on a plate substrate. CONSTITUTION:A pH value changing pattern corresponding to an image signal is formed in an ink. The ink impart with an adhesion according to the pattern is transferred to a plate substrate to form a press plate. An electron pair accepting material, such as hydrochloric acid and organic acid, or an electron pair donative material, such as sodium hydroxide and organic base, is added to the ink, whereby the ink pH shifts to an acid side or an alkali side; in this manner, an process ink 2 having an adhesion is formed. In addition, for example, with use of a peptide compound of amino acid, a pH value shifts to an alkali side by a cathodic reaction due to an electric conduction, and -NH3<+> ion of amino acid is turned to -NH2. On the other hand, the pH value shifts to an acid side by an anodic reaction, and -COO<-> ion of amino acid is turned to -COOH. The change of the amino acid mentioned above causes a change in crosslinked structure, thus generating the difference in adhesive properties.
