Roll-to-roll plasma device for enhancing chemical vapor deposition

The invention relates to a roll-to-roll plasma device for enhancing chemical vapor deposition, which is characterized in that the device comprises a roll-out roller (2), a winding roller (11), a heating cavity (15), a vertical transmission rail (3), a rail (16), tension pulley groups (4,6,13) and a cooling roller (12), wherein the rail (16) connected with a horizontal transmission rail (20) and arranged in a vacuum chamber (22) is used for feeding deposited flexible matrix material into the winding roller (11); the tension pulley groups (4,6,13) are respectively arranged in a vacuum chamber (1), the vacuum chamber (22) and the heating chamber (15) and used for keeping the tensile force of the matrix material in the transmission process, and the cooling roller (12) is arranged in the vacuum chamber (22) and used for cooling the deposited flexible matrix material loaded on the winding roller (11). The device greatly improves the transport efficiency of the flexible matrix in the vacuum cavity, furthermore accurately controls the surface tension of the matrix at high temperature conveniently, and greatly reduces the phenomenon of uneven surface of the flexible matrix caused by thermal contraction at high temperature.

Photogravure press and method for manufacturing multilayer ceramic electronic component

In a print area provided on a peripheral surface of a gravure roll, a plurality of cells are defined by printing-direction walls and perpendicular walls, and each perpendicular wall has a plurality of cuts. In a center portion of the print area, most intersections of the printing-direction walls and the perpendicular walls are defined by T-shaped intersections where the perpendicular walls do not cross the printing-direction walls, but meet the printing-direction walls in a T-shaped arrangement. Preferably, round chamfers are provided at corners where a portion of each printing-direction wall and a portion of each perpendicular wall intersect, and at leading ends of the perpendicular walls pointing toward the cuts.

Coated fiber-reinforced resin molded article and manufacturing method of the same

An object is to provide a manufacturing method of a fiber-reinforced resin that significantly reduces a resin filling defect on the surface and surface irregularity caused by a temperature difference between a molding temperature (curing temperature) and ordinary temperature in the course of molding the fiber-reinforced resin, and a product manufactured by the manufacturing method. There is accordingly provided a manufacturing method of a coated fiber-reinforced resin molded article and a product manufactured by the manufacturing method. The manufacturing method comprises a first molding process that cures a matrix resin which a reinforcing fiber is impregnated with at a temperature T1(° C.) to obtain a fiber-reinforced resin molded article; and a second molding process that places the fiber-reinforced resin molded article in a cavity of a mold, sets the cavity to a temperature T2(° C.) that is lower than the temperature T1(° C.), injects a liquid coating layer-forming resin material into the cavity such as to coat at least part of a surface layer of the fiber-reinforced resin molded article, and cures the coating layer-forming resin material at the temperature T2(° C.), so as to obtain the coated fiber-reinforced resin molded article, wherein the mold is comprised of at least two pieces and has the cavity in a shape that is approximately same as a shape of the fiber-reinforced resin molded article.

Electro-optical device

An auxiliary capacitor for a pixel of an active matrix type liquid crystal display is provided without decreasing the aperture ratio. A transparent conductive film for a common electrode is formed under a pixel electrode constituted by a transparent conductive film with an insulation film provided there between. Further, the transparent conductive film for the common electrode is maintained at fixed potential, formed so as to cover a gate bus line and a source bus line, and configured such that signals on each bus line are not applied to the pixel electrode. The pixel electrode is disposed so that all edges thereof overlap the gate bus line and source bus line. As a result, each of the bus lines serves as a black matrix. Further, the pixel electrode overlaps the transparent conductive film for the common electrode to form a storage capacitor.
