Abstract: A laser processing method for performing laser ablation process on a work piece by radiating laser beam on the work piece includes the step of forming simultaneously a plurality of process shapes arranged at a predetermined interval by use of laser beam of plural pulses having extremely large spatial and temporal energy density radiated from a laser oscillator as the laser beam oscillating at the pulse radiation time of one picosecond or less. With the laser processing method thus structured, it is possible to perform a highly precise processing without creating by-product, as well as to fundamentally prevent the converted thermal energy from being accumulated on a work piece, such as resin, which causes the work piece to be fused or thermally expanded during the operation of laser processing.

Abstract: A method for processing a discharge nozzle of a liquid jet recording head includes bringing a mask plate on which the shape of an ejection orifice to be formed is patterned into close contact with the liquid ejection side of an ejection orifice forming plate on which a plurality of ejection orifices of a liquid jet recording head are formed, and emitting parallel laser beams from the mask plate side, thereby processing and forming a discharge nozzle at the ejection orifice forming plate. Another method for manufacturing a liquid jet recording head includes bringing a mask plate into close contact with the liquid ejection side of an ejection orifice forming plate having a plurality of ejection orifices formed thereon after at least the ejection orifice forming plate and a member for holding the ejection orifice forming plate have been coupled with each other from among members constituting the entire liquid jet recording head, and simultaneously emitting a plurality of parallel laser beams in a direction inclined at a predetermined angle with respect to a vertical axis of the mask plate face, thereby processing and forming a discharge nozzle at the ejection orifice forming plate. In both methods, the closely contacted mask plate and the ejection orifice forming plate are reciprocally scanned by one reciprocation or more along an arrangement for forming the discharge nozzles with respect to a laser bean emission area.

Abstract: A method for manufacturing a liquid jet recording head and a method for manufacturing discharge nozzles thereof through which drops of recording liquid or the like are projected to be deposited on a printing medium. The method for manufacturing the discharge nozzles uses sublimation caused by an ultraviolet laser. In the method, a laser beam is emitted from the liquid ejection side of a discharge port forming plate, and a mask plate having a total-reflection mirror coating layer to prevent it from being damaged is used. The method allows many discharge nozzles, tapered so that they are progressively thinner toward their ends, to be formed on the liquid ejection side of the discharge port forming plate simultaneously in a short period of time.

Abstract: An image forming paper comprises at least pulp, wherein the paper has a spectral reflectance of at least 85% for light diffused-reflected therefrom in a wavelength range of from 440 nm to 640 nm, and a spectral reflectance distribution in which the difference between the maximum and minimum values of the spectral reflectance of the light in the above wavelength range is 5% or less. Therefore, since the amount of light reflected by the paper is large and the reflectance in blue to red regions is constant, color chroma of a color image on the paper is enhanced particularly in green to red regions, and a color reproduction area of the color image is enlarged.

Abstract: In an optical scanning apparatus, a light beam emitted from a light source is collimated and is incident on a reflecting surface of a deflector via stop member. The deflector deflectively reflects the light beam to be directed to a surface to be scanned. The light beam deflectively reflected by the deflector is converged on the surface to be scanned by an optical system. The stop member has an aperture which is constructed such that a circular shape aperture and a slit-like shape aperture are combined. The width of the slit-like shape aperture is arranged in a sub-scanning direction while the circular portion of the circular shape aperture is arranged in a main scanning direction.
