摘要： PROBLEM TO BE SOLVED: To remove excess power efficiently with small energy and to reuse the collected excess power for developing an image. SOLUTION: In an image forming apparatus for forming a latent image on a recording medium by ejecting liquid drops by ink jet system, applying adhesive powder between the liquid drop and developing an image, powder sprayed excessively (excess powder 14) onto a recording medium 11 from a powder diffusion chamber 3 is removed by attracting electrostatically to an electrostatic drum 6. The removed excess powder 14 is scratched by means of a blade 7 and returned back to a powder tank 4 through a collecting pipe 18 by means of a powder transfer pump 9. According to the method, excess powder 14 is removed efficiently with small energy and the collected excess power 14 can be reused for developing an image.

摘要： PROBLEM TO BE SOLVED: To record images having a nearly uniform image area and a gradational image area with good quality, by providing a first recording means for recording gradational images by a recording head, and a second recording means for recording images of a nearly uniform density with the use of all of a plurality of recording agents of the recording head. SOLUTION: In recording images, pixels of pixel values in a range 255-192 among pixels of input image data are binarized by a CPU 103 with a threshold value of a pixel value 224. The obtained pixels are stored as an output image data M1 in a RAM 106. Pixels of pixel values in a range 191-128 are binarized with the threshold value of a pixel value 160. The obtained pixels are set as an output image data M2 and those of the data M2 having a pixel value 0 are stored as pixels of the output image data M1. Then, a background area and a gradational image area are determined on the basis of the generated output image data. The background area is recorded with the use of all ink on a recording head.

摘要： PURPOSE: To enhance the abrasion resistance of slide protruding parts by supplying a thermoplastic resin to the nip between a roll mold having scale patterns provided to the peripheral surface thereof and a roll to transfer the scale patterns and providing the slide protruding parts so as to hold the scale patterns therebetween. CONSTITUTION: A stamper 8 is fixed to the surface of a stamper roll 2 and a first roll 1 is arranged in opposed relation to the stamper roll and a large number of scale patterns for an optical scale are formed to the surface of the stamper 8. A molding material is extruded to the nip between the first roll 1 and the stamper roll 2 from a T-die 4. Whereupon, the scale patterns are transferred to the surface of the stamper 8. At this time, an easy slide material is supplied only to the parts corresponding to the slide protruding parts of the scale patterns on the stamper 8 from a dispenser 5 through nozzles 6 and integrated with the molding material to form the slide protruding parts. This optical scale sheet 7 is fed by a third roll 3 and cooled to be punched to obtain individual optical scales.

摘要： PURPOSE: To produce a substrate for optical recording medium stably with low birefringence and high transfer rate by controlling the molding conditions such that the line pressure of a resin, held between a first mirror face roll and a stamper roll, is sustained at a predetermined level. CONSTITUTION: A first mirror face roll 5 is pressed against a second roll (stamper roll) 6 by the hydraulic pressure of hydraulic cylinders 3, 4 with output sensors A, B. In this regard, the force of the hydraulic cylinders 3, 4 minus the force of gap regulating members 1, 2 With pressure sensors A, B act continuously between the first mirror face roll and the second roll 6. The line pressure being applied to a resin at the time of molding is determined by dividing the differential force by the width of a resin sheet. A computer sets the molding conditions by specifying the line pressure which is sustained by controlling the pressure, molding speed, gap, etc. This method realizes stabilized production of a substrate for optical molding medium with low birefringence and high transfer rate.

摘要： PURPOSE:To provide a process for production of the stamper master disk which is capable of forming a 2P resin replica without intruding and protruding of air bubbles, yields the 2P resin replica having good transferability without the danger of degrading flatness by deflection at the time of injecting the 2P resin into a cell and is much higher in injection rate than that in the conventional methods. CONSTITUTION:A cell 4 formed by hermetically disposing an original mold 1 having rugged patterns and a substrate 2 opposite to each other via spacer materials 3, 3' at their peripheral edges and central parts is placed in a vacuum chamber 6 and the pressure in this chamber is reduced. An injection hole 5 is thereafter immersed in a photosetting resin 9 and the pressure in the chamber is increased to suck the photosetting resin 9 into the cell 4. The photosetting resin is thereafter irradiated with light to cure the photosetting resin, and the hardened resin replica of the original mold is obtd.

摘要： PURPOSE:To provide the method capable of producing the substrate having excellent thickness accuracy by clamping and pressing a thermoplastic resin while bringing a roll stamper and a forming roll into contact therewith via a gap regulating means. CONSTITUTION:The roll stamper 102 is constituted by fixing a flexible stamper on the peripheral surface of a roll base material 109 and forming the gap regulating means 108 in the region exclusive of the region where the thermoplastic resin sheet 106 comes into contact. The roll stamper 102 and the forming roll 104 clamp and press the resin sheet 106 while the stamper and the roll are pressed to each other so as to come into contact with each other via the gap regulating means 108. The dependency of the gap formed of the roll stamper 102 and the forming roll 104 in which the resin sheet 106 passes on the eccentricity of the respective rolls is eliminated by such constitution. The substrate sheet 107 for the optical recording medium having the excellent thickness accuracy of preformat patterns 103 is thus produced at a low cost.

摘要： PURPOSE:To prevent the generation of an uneven flaw or transfer irregularity in the fine uneven pattern of a substrate for a data recording medium molded by a roller group molding method by providing a heat insulating layer to the interior of a flexible stamper. CONSTITUTION:A photoresist film is formed on a glass substrate and exposed and developed to form an uneven pattern. A conductive film and a metal film due to an electroforming method are successively formed thereon. After the surface of the metal film is ground, a heat insulating layer 2 such as a polyimide film having heat conductivity lower than that of the metal film is formed. The conductive film and the metal film are again formed on the layer 2 to be ground and the glass substrate is released to form a flexible stamper 1. The fixing jig 24 of this stamper 1 is welded to be fitted in the groove provided roller to form a roll-shaped stamper for molding a roller group. Further, a flexible stamper 23 may be formed by a known method to provide a porous layer 22 between the stamper 23 and a mirror surface roller 21.
