摘要:
A spray-type dampening water supply apparatus having a spray unit whose nozzles (10, 20, 30, 90) are protected against adhesion of any foreign matter to the nozzle surfaces and in which at least orifices (13, 23, 33, 93) of the nozzles (10, 20, 30, 90) can be easily cleaned out. Each nozzle of the spray has a guide surface (1, 2, 3) slanting from an upstream outer peripheral edge toward a downstream central orifice. A partition (40, 50, 60) of the spray is disposed downstream of the nozzle assembly and has a plurality of apertures (41, 51, 61) confronting the respective nozzles. The spray is equipped with means (70) for opening and closing the apertures (41, 51, 61) of the partition (40, 50, 60).

PROBLEM TO BE SOLVED: To solve the problem that stain is easy to stick and accumulate on a nozzle surface and cleaning of the nozzle ejection port is insecure and difficult, and, as a result, a stain prevention system may become inevitably large-sized, in a conventional nozzle. SOLUTION: A spray type damping water feeding apparatus supplies damping water by spraying through a nozzle 10 to the peripheral face of a roller R which leads to the printing plate face or the printing plate of an offset printing machine P, in which the nozzle 10 has a guide face 1 which slants toward the center ejection port 13 on the downstream side in the damping water ejection direction from the outer peripheral side on the upstream side in the damping water ejection direction, a partition wall member 40 is provided with an opening port 41 at a position facing against the ejection port 13 of the nozzle 10, and a spraying apparatus is provided with an opening/closing means 70 capable of opening/closing the opening port 41.

PROBLEM TO BE SOLVED: To provide a system, an apparatus and a method for coating a mixture of two liquid components stored in respective containers. SOLUTION: Two liquid components stored in respective containers 19 are discharged through respective delivery ports 8 in respective delivery port passages 5 in a nozzle head 1. Also, gas is discharged through an individual delivery port in a gas delivery port passage in the nozzle head 1. The delivery ports 8 are aligned substantially along a straight line. The gas is discharged through the delivery port at one end of the straight line of the delivery ports. The volume stream of the gas is rendered suitable for a volume stream of each component so that each component is caught in a jet discharged through the gas delivery port outside of the nozzle 1.

PROBLEM TO BE SOLVED: To provide an evaporating device capable of restraining blockage of a carrier gas outlet at a tip of an injection nozzle part for evaporating a liquid raw material.SOLUTION: An evaporating device 12 for forming a raw material gas by evaporating a liquid raw material 60 with carrier gas comprises: an evaporation vessel 96, in which an evaporation chamber 94 is formed; an injection nozzle part 64 having a nozzle 122 for the liquid raw material emitting the liquid raw material at a center, and having a nozzle 124 for the carrier gas concentrically emitting the carrier gas to an outer periphery of the nozzle for the liquid raw material to form the raw material gas; a gas diffusion restraining block 100 whose opening angle gets enlarged at a sharp angle in an injection direction of the liquid raw material from the injection nozzle part to form a gas diffusion restraining region 130 opened toward the evaporation chamber; and a raw material gas outlet 84. This restrains blockage of the carrier gas outlet at the tip of the injection nozzle part evaporating the liquid raw material.
