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.

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.

A composition for preventing or treating an eye disease includes adiponectin as an active ingredient. Adiponectin as an active ingredient is eventually revealed to show prevention or therapeutic efficacies for eye diseases such as dry eye (syndrome), inflammatory eye disease and side effects due to the use of contact lenses by promoting tear secretion, alleviating ocular surface irregularities, decreasing inflammatory cytokines on the ocular surface and lacrimal gland, and increasing conjunctival goblet cell density. In addition, the composition having eye contact lubrication effects may be used as cleaners or lubricants for preventing non-bacterial inflammation due to wearing contact lenses.

A fuel cell includes a laminated, plate-shaped membrane electrode assembly and first and second separator plates sandwiching the membrane electrode assembly. The membrane electrode assembly includes a polymer electrolyte membrane; first and second electrode layers sandwiching the polymer electrolyte membrane; and first and second gas-diffusion layers disposed on an outer side of the electrode layers, respectively. The first and second gas-diffusion layers are made of an air-permeable metallic material. An arithmetic average roughness Ra of a surface of the air-permeable metallic material on the side contacting one of the electrode layers is in a range of 0.1 μm≦Ra≦1.0 μm.

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.

The invention discloses an intraoperative protective mirror. The protective mirror comprises an outer lens surface and an inner lens surface, and is characterized in that the outer lens surface and the inner lens surface consist of two arc surfaces; and the outer lens surface and the inner lens surface are connected into a whole to form a bowl-shaped transparent lens body. The invention also discloses an application of the intraoperative protective mirror in the vitrectomy. A method comprises the following steps of: finishing operation preparation, and smearing a corneal protective agent on the corneal surface; placing the intraoperative protective mirror above the corneal protective agent after the corneal protective agent is smeared; and after the contact surface of the intraoperative protective mirror and the corneal protective agent has no bubbles, carrying out the operation. The protective mirror can avoid or reduce the use of a balance liquid and the corneal protective agent, save the operation time, make images more clear in the operation, reduce the operation difficulty and improve the comfort level of the patient.

A hydroentangled nonwoven sheet material can be produced by a process which comprises: 0) optionally providing a polymer web on a carrier, a) providing an aqueous suspension containing short fibres and a surfactant; b) depositing the aqueous suspension on the carrier, c) removing aqueous residue of the aqueous suspension deposited in step b) to form a fibrous web, b') depositing aqueous suspensionon a surface of the fibrous web formed in step c), c') removing aqueous residue of the aqueous suspension deposited in step b') to form a combined fibrous web, d) hydroentangling the combined fibrousweb, and optionally e) drying the hydroentangled web, and/or f) further processing and finalising the dried, hydroentangled web the web to produce the nonwoven end material. The hydroentangled non-woven sheet material obtainable by this process has a low degree of surface irregularity and contains low residues of surfactants.
