Title: Color image forming device
Inventor: TAKEUCHI AKIHIKO
IPC: G03G15/01
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent the scattering of a color character or a color line at the time of superposing colors by taking a black toner image as a toner image transferred first from an image carrier to an intermediate transfer body. SOLUTION: This device is provided with the image carrier 1, developed image forming means 2 to 4, the intermediate transfer body 5, a 1st transfer means 6 and a 2nd transfer means 7. The developed image is formed on the image carrier 1 by the means 2 to 4 and temporarily primarily transferred to the transfer body 5 by the transfer means 6, then the developed image on the transfer body 5 is transferred on transfer material P such as paper by the transfer means 7. The first toner image transferred to the transfer body 5 from the image carrier 1 at the 1st transfer position by the transfer means 6 is the black toner image. Since the black toner is only used as little inking (UCR processing), it is not used much for the color character or the color line. Therefore, the scattering of the color toner superposed on the black toner does not become trouble in practical use.

Filed: 1989-03-28
Abstract: PURPOSE:To obtain a composite film having excellent adhesiveness and adapt able to various uses by constituting said film of a liquid-crystalline polymer layer containing a thermotropic liquid-crystalline polymer and a thermoplastic polymer layer containing polyester. CONSTITUTION:This composite film is constituted of a liquid-crystalline polymer layer containing a thermotropic liquid-crystalline polymer and a thermoplastic polymer layer containing polyester. The liquid-crystalline polymer is selected as a combination of polyesters each composed of constitutional component consisting of one or more kind of aromatic dicarboxylic acid and alicyclic dicarboxylic acid and one or more kind of aromatic diol, alicyclic diol and aliphatic diol. The polyester contained in the thermoplastic polymer layer contains polyvalent carboxylic acid as a constitutional component and polyvalent carboxylic acid can be used in a mixed state. For example, the composite film may be formed as a two-layered structure wherein the liquid-crystalline polymer layer 1a is laminated to the thermoplastic polymer layer or may be constituted by forming thermoplastic polymer layers 2b, 12b to both surfaces of the liquid- crystalline polymer layer 1b.

Title: Pretreatment for plating
Inventor: NAKANO TADASHI
IPC: C25F1/00
Filed: 1991-02-28
Abstract: PURPOSE:To sufficiently degrease and mirror-finish a material to be plated by impressing a DC current having ripples alternately on the anode side and on the cathode side. CONSTITUTION:When a material to be plated is electrolytically degreased as pretreatment, a DC current on which ripples (pulse) are superimposed is impressed alternately on the anode side and on the cathode side. In this case, Y >0.421XX+5.789 is preferably fulfilled, where Y is the impressing time of the anode and X is the impressing time of the cathode. A smooth mirror finish is attained by using a DC current having ripples and appropriately selecting the parameters (the frequency of ripples and the ratio of the impressing time of the anode to that of the cathode). Good heat-resistant adhesion is obtained between the plating layer and the material by this pretreatment.
