Title: Transfer paper for wet electrophotography
Inventor: KAJI HIROO
IPC: G03G7/00
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To improve the fixability of a toner after printing by coating the surface of transfer paper having a specified ash content with a specified amt. of a specified Zr compd. SOLUTION: The surface of transfer paper for wet electrophotography having 5-20wt.% ash content is coated with 0.05-1.00g/m<2> (expressed in terms of ZrO2 ) at least one kind of Zr compd. selected from among ammonium zirconium carbonate, potassium zirconium carbonate, zirconium sulfate, zirconium nitrate and zirconium acetate. Such a Zr compd. is generally used as an adhesiveness improver or a crosslinking agent in an adhesive or ink. At the time when a liq. toner reaches the surface of the transfer paper coated with the Zr compd. before printing, the Zr compd. forms a complex with a polar group existing in the toner and the fixability of the toner on the surface of the paper is improved. Work efficiency after printing is enhanced.

Title: Position alignment apparatus
Inventor: MITOMI TAKASHI
IPC: B25J13/08
Filed: 1990-11-29
Abstract: PURPOSE:To execute position alignment of a moving body with an object highly precisely in a short time without being affected by instruction precision, by determining the relationship in relative positions on the basis of positional information obtained by recognizing a shadow from the object and two shadows formed by two light sources. CONSTITUTION:An image processing element 13 in a controller 5 recognizes first the position of a shadow formed by a hole 8 from a pattern of a laser light sensed by a camera 3, according to an instruction from a central control element 11. Next, the position of a shadow 9 of the fore end of a component 6 which is formed on a workpiece 7 by a light projected from a light source 2a and intercepted by the component 6 and the position of a shadow 10 of the fore end of the component 6 which is formed on the workpiece 7 by a light projected from a light source 2b and intercepted by the component 6 are recognized by template matching. Recognized position data thus determined are sent to the control element 11 and the relationship in relative positions of the position of the hole 8 and the position of the fore end of the component 6 is determined three-dimensionally from those positions of the fore end of the component 6 and the pattern of the hole 8. According to this constitution, position alignment of a moving body with an object can be executed highly precisely in a short time irrespective of instruction precision.

IPC: H04N1/387
Filed: 1993-12-28
Abstract: PURPOSE:To output beautiful multi-level void data to an output device capable of gradation expression by providing a multi-level data holding means, a multi- level thickened data generating means, a multi-level data inverting means, and an inverted data overwrite means. CONSTITUTION:Multi-level data as the object of void processing is held in a multi-level data holding means 1, and a multi-level thickened data generating means 3 generates multi-level thickened data, whose outline part corresponds to the gradation value, from multi-level data held in the means 1. The multi- level data inverting means 2 inverts the gradation value of each picture element of multi-level data held in the means 1 to generate the void part whose outline part corresponds to the gradation value. An inverted data overwrite means 4 writes only values of picture elements, which are effective and are other than those in the original background part, out of picture elements inverted by the means 2 over the picture elements of multi-level thick data generated by the means 3. Thus, multi-level void data where outline parts of the inside and the outside are multi-level is generated from multi-level data.

Title: Method and device for surface polishing wire material
Inventor: SUGIYAMA SATOSHI
IPC: B24B29/00
Filed: 1993-12-28
Abstract: PURPOSE:To provide favorable surface polishing without changing polishing material by filling a closed space of a wedge-like form with grain material for polishing, and running a wire material through it, so the grain material for polishing flows as the wire material runs to get in contact with the surface of the wire material. CONSTITUTION:A wire material 1 is supplied through a cylindrical body 4, grain material 5 for polishing is injected from an injection port 9 after that to fill the inside of the cylindrical body with the grain material 5 for polishing. In polishing, the injection port 9 is closed with a cap 10 for preventing leak of the grain material 5 outside. As polishing is started by running the wire material 1 by a wire material takeup means, the grain material 5 inside the cylindrical body 4 flows in a wedge-shaped space in the cylindrical body 4 to generate loop currents as illustrated with arrows. The grain material thus flows along the wire material l to fold back at the position of a nipple 8 to get apart from the wire material 1, where loop currents in inverse directions are generated. The grain material 5 to get in contact with the wire material 1 is always renewed to have high polishing ability, thereby favorable polishing can be assured for a long time.
