A method for manufacturing laminated printed matter includes the steps of ejecting, by an ink jet process, a colorant-containing active-radiation-curable ink composition onto a recording medium; ejecting, by an ink jet process, a colorant-free or white-pigment-containing active-radiation-curable ink composition into a non-image area adjoining an image area formed by the colorant-containing ink composition; curing the ejected colorant-containing ink composition and the ejected colorant-free or white-pigment-containing ink composition by irradiation with active radiation to form an image layer; and laminating a lamination film on a surface on which the image layer has been formed. Laminated printed matter has, in sequence, an image layer and a lamination film. The image layer is composed of an image area and a non-image area. The non-image area is formed of a cured product selected from the group consisting of transparent cured products and white cured products. The non-image area adjoins a side of the image area in a direction along the plane of the recording medium.

A system for cooling rolling mill material is provided that includes a conveyor system that receives rolling mill material and passes the rolling mill material through one or more cooling regions. A cooling structure that operates uniformly across the central and edge regions of the conveyor system. The cooling structure uses a first jet of air for cooling the central portion of the rolling mill material. A nozzle deck is positioned on the edge regions of the conveyor system produces a second of jet of air for cooling the edge portions of the rolling mill. The nozzle deck includes one or more adjustable nozzle structures for controlling the air flow produced by the second jet of air by varying the size of their air passage regions.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

A drying device includes: a housing having a ventilation device provided therein; a drying nozzle provided in the housing, and having a ventilation groove from which an air flow generated by the ventilation device is discharged; and a driving motor for moving the drying nozzle forward and backward by rotating the drying nozzle.

A drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. The drain clearing air gun additionally includes a tank at least partially positioned within the housing and including a chamber for receiving pressurized air, a motor positioned within the main body of the housing, and a pump positioned within the main body of the housing and operatively coupled to the motor. The pump is driven by the motor to pump air into the tank. The drain clearing air gun also includes a connection mechanism coupled to the nose. The connection mechanism includes a receiving member configured to releasably couple to a plurality of accessories.

According to one embodiment, a rectifying plate is opposed to a plurality of nozzles which are configured to inject a fluid. The rectifying plate is configured to rectify the fluid. The rectifying plate includes: a plurality of high flow path resistance areas, and a low flow path resistance area. Each of the high flow path resistance areas includes a nozzle-facing area which is opposed to one of the plurality of nozzles. The low flow path resistance area surrounds each of the plurality of high flow path resistance areas. The low flow path resistance area includes a plurality of first through-holes to allow the fluid to pass through and having a smaller flow path resistance of the fluid than that of the high flow path resistance area.
