摘要:
This invention relates to a curtain applicator on which a two-layer curtain is formed by dispensing two types of coating medium, for example color, from a medium feeder positioned to the upper side of a moving web in order to apply two layers of coating medium onto the web surface. The medium feeder has a middle lip, which is arranged in the flow channels for the two types of medium and has a pointed part projecting toward the web side from the pointed parts of the two side lips which are arranged on the outer side of the flow channels for the two types of medium on the outer side in the width direction of the web. The curtain applicator also includes a convexly formed medium separation device, which adjoins the pointed part of the middle lip and individually separates the two types of surplus medium, for example, color, which are dispensed from the medium feeder.

Curtain-type coater and process for coating a web with curtain-type coater. Curtain-type coater includes a curtain head having a slit structured and arranged to supply a coating liquid curtain onto a surface of a web and outside of the edges of the web. At least a portion of the slit forming the coating liquid curtain outside the edges of the web has a width greater than a portion of the slit forming the coating liquid curtain supplied onto the web.

The present invention provides a 2-layer curtain coater that supplies a 2-layered paint curtain formed from a first paint curtain and a second paint curtain to the surface of a transported web to overcoat a first paint and a second paint in two layers on the surface of the web, the 2-layer curtain coater being able to prevent paint loss during coating preparation. The 2-layer curtain coater includes a first curtain nozzle for the forming of the first paint curtain and a second curtain nozzle for the forming of the second paint curtain and, in addition, in that the first curtain nozzle and the second curtain nozzle are relatively movable between a segregated coating preparation position and a merged coating operation position wherein, in the coating preparation position, the first paint and the second paint are recovered in a state independent of each other by the recovery of the first paint curtain from the first curtain nozzle by way of a first recovery pan and the recovery of the second paint curtain from the second curtain nozzle by way of a second recovery pan and, in the coating operation position, the 2-layered paint curtain is formed from the first paint curtain from the first curtain nozzle and the second paint curtain from the second curtain nozzle to overcoat the first paint and the second paint in two layers on the surface of the web.

In a heat exchanger having a side plate for reinforcing a core portion, after an elastic support member for supporting the core portion is inserted between opposite walls of the side plate, a part of the opposite walls having a slit portion is plastically deformed at a position around the slit to form a protrusion. The protrusion protrudes toward the support member to be engaged with a recess of the elastic support member. Further, the silt is provided to penetrate through each opposite wall without being opened to an outer peripheral end of the side plate. Accordingly, the support member can be readily attached to the side plate, while it can prevent the side plate from being deformed in a brazing.

A plastic optical element for focusing light to a target includes a first lens and a second lens. The first lens includes an incident surface, a projection surface opposite the incident surface, and a non-optical surface through which light does not pass and that includes a non-transfer portion. At least one light beam passes from the incident surface to the projection surface. The second lens includes an incident surface, a projection surface opposite the incident surface, and a non-optical surface through which light does not pass and that includes a non-transfer portion disposed opposite the non-optical surface of the first lens. At least one light beam passes from the incident surface to the projection surface. The non-transfer portions of the first lens and the second lens are portions on which no surface is transferred from a surface of a mold used to form the plastic optical element.

A molded plastic part prepared by injecting a resin in a cavity of a die so that a pressure is generated in the resin in the cavity and at least one transfer wall surface of the cavity is transferred to the resin. The plastic part has at least one transferred surface; at least one imperfectly transferred concave portion on a first surface thereof other than the transferred surface; and at least one imperfectly transferred convex portion on the first surface or a second surface thereof other than the transferred surface. The ratio (a)/(b) of the thickness (a) of the plastic part in a direction perpendicular to the transferred surface to the thickness (b) of the plastic part in a direction parallel to the transferred surface is less than 1.

A cover assembly for an aperture in a wall may include: a first support and a second support provided on the wall, each support including a monolithic receptacle; a first pin-portion and a second pin-portion rotatably mounted in the receptacles, respectively, to define respective pivot-hinge arrangements; and a cover coupled to the first and second pin-portions. For example, the wall may be a part of fluid (e.g., air) duct disposed in a vehicle, and the cover may be oriented with respect to the wall so that the aperture represents one of an inlet and an outlet.
