摘要： The ink jet head records an image on a recording medium by ejecting ink containing charged fine particles by means of an electrostatic force, and includes an ink guide, an ink flow path that supplies the ink to the ink guide and an ejection electrode that ejects the supplied ink. The ejection electrode includes a surrounding electrode arranged so as to surround an outer periphery of the ink guide with a spacing, or side-by-side electrodes arranged on both sides of the ink guide so as to oppose each other with a spacing. A ratio between an effective inside diameter of the surrounding electrode or an effective spacing between the side-by-side electrodes, and a distance from the surrounding electrode or the side-by-side electrodes to a tip end of the ink guide protruding on the side of the recording medium is set in a range of 1:0.5 to 1:2 or 1:0.7 to 1:2.8, respectively.

摘要： The improved transporting apparatus for scanning exposure of a recording material as it is fixed on an exposure mount which is moved by means of a screw transmission mechanism is characterized in that the exposure mount for transporting the recording material is composed of a platen for carrying the recording material and a transport plate that holds the platen and which engages the screw transmission mechanism, with the platen and the transport plate being designed to be capable of relative displacement by small amounts, preferably in a non-contact relationship. Optionally, urging members may be provided to combine with the platen and the transport plate to form a vibration system that composes a vibration filter. The apparatus effectively absorbs not only vibrations that originate from the drive system to be transmitted to the exposure mount via the travelling nut of the screw transmission mechanism, as exemplified by erratic rotation or vibrations of the motor and the screw shaft of the screw transmission mechanism, but also vibrations due to externally applied forces and, hence, highly precise scanned transport of the recording material can be accomplished while suffering from very small levels of unevenness in the speed of its transport that will occur on account of those unwanted vibrations.

摘要： A method for preparing a lithographic printing plate not requiring dampening with water comprising the steps of imagewise exposing to light a presensitized plate for use in preparing a lithographic printing plate not requiring dampening with water which comprises a substrate provided thereon with a light-sensitive layer and a silicone rubber layer in that order and then spraying a pressurized liquid on the plate surface to remove the silicone rubber layer of the image areas. The method does not require the use of brush rolls or developing pads which directly come in contact with the plate surface and give rise to wear and/or bending. Therefore, the method always ensures excellent quality and uniformity of development. Further, the method may be carried out repeatedly with less maintenance of equipment since it is not necessary to use any developing pad or brush roll which must frequently be exchanged due to wear or bending.
