摘要： PROBLEM TO BE SOLVED: To obtain an ink sheet type printer in which print image quality is enhanced while using an ink sheet 2 efficiently to avoid waste thereof. SOLUTION: A roll ink sheet 2 in divided imaginarily into a plurality (q) of groups (D0-D(q-1)) in the sub-scanning direction 6 wherein a plurality (p) of print areas R1-Rp are formed on each group while being shifted in the sub- scanning direction 6. Each print area is divided imaginarily into a plurality of blocks over the main scanning direction 7 and the sub-scanning direction. For each block 15, a second accumulated print rate η2 by an image being printed next is operated using a first accumulated print rate η1 after printing, and an evaluation value G is operated for each print area dependent on the second accumulated print rate η2 among a plurality of print areas comprising only such blocks as the second accumulated print rate η2 is not higher than a predetermined value η0. Based on the evaluation value, a print area requiring a small quantity of ink is used and printed.

摘要： PROBLEM TO BE SOLVED: To provide a small and lightweight recorder having a high integration recording head performing high quality high speed gradation printing without requiring replacement in which power consumption and manufacturing cost can be reduced. SOLUTION: An ink feeder 3 feeds an UV-curing ink 4 to an intermediate transfer body 2. An UV-curing head irradiates the UV-curing ink 4 on the intermediate transfer body 2 with ultraviolet rays and cures the UV-curing ink 4 selectively according to an image pattern. A platen 9 brings a recording medium 6 into contact with the intermediate transfer body 2 and tfansfers uncured UV-curing ink 4 to the recording medium 6. A fixing/curing unit 7 cures the ink transferred onto the recording medium 6. An ink removing unit 8 removes residual ink on the intermediate transfer body 2.

摘要： PROBLEM TO BE SOLVED: To enhance the dynamic characteristics, durability, etc., of the head by forming a buckling structure, as a pressure producing means, on a substrate and fixing a diaphragm thereon through a coupling member and then removing a film layer thereby obtaining a diaphragm having flat surface. SOLUTION: Silicon oxide containing phosphorus (PSG layer) is deposited on the surface and rear of a single crystal silicon substrate 8 having orientation (100). A resist pattern is then formed thereon followed by formation of a nickel layer at the unpatterned part thus forming a buckling structure 1 of nickel layer. Subsequently, a PGS layer is formed in the center of buckling structure 1, a resist pattern is formed and eventually removed thus forming a coupling member 4. Finally, a diaphragm 2 previously deposited on a film having flat surface is fixed through the coupling member 4 to the buckling structure 1 and the film layer is removed to obtain the ink jet head.

摘要： PROBLEM TO BE SOLVED: To improve chemical resistance and heat conductivity by having a heater formed of a metal film and an insulating film of covering the heater, forming in this insulating a contact side with a heater metal of an SiOy film, forming a contact side with the outside atmosphere of an SiNx film, and enhancing adhesion to the metal film. SOLUTION: An insulating film is formed into a two-layer structure in both upper/lower part of a heater, to provide a structure of laminating SiNx film 3, 4 and SiOy films 5, 6. A contact side with the outside atmosphere is set to the SiNx films 3, 4, and a contact side with a heater metal 9 is set to the SiOy films 5, 6. This insulating film is formed as follows. First as a bed insulating film, the SiNx film 3 in formed by reactive sputtering of Ar and O2 by using a sputter device of Si target on a substrate. Next on the SiNx film 3, a sputter device of Si target is used to form the SiOy film 5 by reactive sputtering of Ar and O2 . Next a heater layer 9 is formed. On the film 5, metal for a heather, for instance, Ni is molded by sputtering method, next to be worked by photolithography and etching method, to from a heater pattern 9, so as to similarly form on this pattern the SiOy film 6 and SiNx film 4.

The substrate 6 is made of transparent material and a second reference surface 4b capable of applying a spherical abberation to the light beams when the flexible member 1 is attracted to it is formed on the substrate 6. The reference surface 4b has the curvature of a direction opposite to that of the reference surface 4a. The flexible member 1 is absorted to one side of either the reference surface 4a or the reference surface 4b by the absorption changeover of the driving device 9.
