Patent number: 6494627Abstract: An image-recording apparatus including a casing section that encases a light and heat sensitive recording material therein; an optical recording section that exposes to light a light and heat sensitive recording material fed from the casing section, and thereby records a latent image thereon; a thermal developing section that develops the latent image with heat; a moisture content-controlling section that controls moisture content of the light and heat sensitive recording material after exposure and before development; and an optical fixing section that fixes the developed image by irradiating it with light. The image-recording apparatus can be a completely dry system that is capable of forming good print images without producing waste materials such as image transfer sheets. By controlling moisture content of the recording material, problems such as mottling of images can be prevented.Type: GrantFiled: April 30, 2001Date of Patent: December 17, 2002Assignee: Fuji Photo Film Co., Ltd.Inventors: Nobufumi Mori, Akinori Harada, Shun-ichi Ishikawa, Shintaro Washizu

Publication number: 20020170987Abstract: An injector has an orifice plate formed with plural orifices. At a radially outward position of the orifice plate is disposed a wall at least partially. It is preferable that the wall be disposed at a lower position in the direction of gravity. In the wall is formed a guide hole toward an area on the orifice plate where a strong negative pressure is developed. A portion of fuel injected from the injector adheres as adhered fuel to the orifice plate or the wall. Under the action of a negative pressure on the orifice plate the guide hole sucks in the adhered fuel and returns it onto the surface of the orifice plate. The adhered fuel flows from the wall onto the surface of the orifice plate and again joins a fuel jet injected from the orifices. By utilizing a negative pressure developed near the plural orifices, the adhered fuel can be recovered and again injected. Consequently, it is possible to decrease the amount of adhered fuel.Type: ApplicationFiled: April 9, 2002Publication date: November 21, 2002Inventors: Fumiaki Aoki, Nobuo Imatake, Kimitaka Saito, Kenji Kanehara, Akinori Harada

Publication number: 20020015595Abstract: An image-recording device that improves processing speed for image-recording that is carried out using a light and heat sensitive recording material. At the same time as irradiation of the light and heat sensitive recording material with light by a light source for fixing, a heating device heats the light and heat sensitive recording material. Because photo-fixing/photo-decolorization is carried out while the light and heat sensitive recording material is heated, viscosity of the system decreases, and dispersibility of active radicals increases. Due to this activation of radicals, a photopolymerization reaction and a photo-decolorization reaction accelerate, so that efficiencies of fixing and decolorizing increase.Type: ApplicationFiled: May 15, 2001Publication date: February 7, 2002Applicant: FUJI PHOTO FILM CO., LTD.Inventors: Akinori Harada, Shintaro Washizu

Publication number: 20010055491Abstract: When a recording starting point of a color photosensitive material reaches a position on which light beams are focused by a condenser lens and a reflecting mirror, a light beam is emitted from a red organic EL element of a light source by a controller, and red image data corresponding to a plurality of lines is transferred to a DMD. In accordance with the image data, on-off control of micromirrors of the DMD is carried out, and the red light beam emitted from the light source is made incident on the DMD. When the micromirrors are on, the incident light beam is reflected toward the reflecting mirror. The light beam is focused onto a recording surface of the color photosensitive material by the condenser lens and the reflecting mirror, and red exposure is carried out. Subsequently, green exposure and blue exposure are carried out in the same way.Type: ApplicationFiled: June 25, 2001Publication date: December 27, 2001Applicant: FUJI PHOTO FILM CO., LTD.Inventor: Akinori Harada

Publication number: 20010003032Abstract: A plate-making method is capable of recording a sharp image on a photosensitive plate, and is applicable to a process operation executed in a light room, while adverse influences caused by laser flares can be hardly received. Ultra-short pulse laser light emitted from a Ti:Al2O3 laser light source is modulated by an AOM (acousto-optic modulating element). The modulated laser light is focused by a collective lens onto a high-sensitive photopolymer layer of a photosensitive plate-making material. The focused ultra-short pulse laser light may cause a photopolymerization reaction in a laser-light-irradiated portion of the high-sensitive photopolymer layer by way of a multiple photon absorption phenomenon, so as to form a hardened portion.Type: ApplicationFiled: December 1, 2000Publication date: June 7, 2001Inventors: Akinori Harada, Nobufumi Mori

Patent number: 5744073Abstract: A method for fabricating domain reversals in predetermined periods without the occurrence of localized variations in refractive index. Localized areas of a unipolarized ferroelectric material which is made of an LiNbO.sub.3 substrate, or the like, and possesses a nonlinear optical effect are exposed to electron beams in a predetermined pattern, so that domain reversals are defined. Thereafter, this ferroelectric material is subjected to a heat treatment at a temperature below the Curie temperature of the ferroelectric material.Type: GrantFiled: September 20, 1995Date of Patent: April 28, 1998Assignee: Fuji Photo Film Co., Ltd.Inventors: Yasukazu Nihei, Yoji Okazaki, Akinori Harada

An earth electrode is formed on one surface (the +z plane) of a ferroelectric substance. Domain reversals are created on the opposite side (the -z plane) of the substrate relative to the +z plane by irradiating electron beams onto the -z plane.Type: GrantFiled: July 8, 1994Date of Patent: September 16, 1997Assignee: Fuji Photo Film Co., Ltd.Inventors: Yasukazu Nihei, Akinori Harada

Patent number: 5652757Abstract: In an optical wavelength converting apparatus, a fundamental wave impinges upon a crystal of a nonlinear optical material, the type II of phase matching between the fundamental wave and its second harmonic is effected, and the second harmonic of the fundamental wave is thereby radiated out of the optical wavelength converting apparatus. Two crystals constituted of the same material are employed as the crystal. The two crystals have equal lengths and are located in orientations such that corresponding optic axes may be shifted 90.degree. from each other. The optical wavelength converting apparatus yields the second harmonic having the maximum possible output power and yet can be kept small in size and low in cost.Type: GrantFiled: June 19, 1996Date of Patent: July 29, 1997Assignee: Fuji Photo Film Co., Ltd.Inventors: Yoji Okazaki, Chiaki Goto, Hiroaki Hyuga, Akinori Harada

Patent number: 5594746Abstract: An electrode is formed in a predetermined pattern on one surface of a unipolarized MgO-LiNbO.sub.3 substrate that is a ferroelectric substance and possesses a non-linear optical effect. The substrate is subjected to corona electrical charging by the electrode and a corona wire disposed above another surface of the substrate which is opposite to the electrode-side surface, and hence an electric field is applied to the substrate. When localized domain reversals are created on areas where the electrode faces the substrate, a vessel is attached to the electrode-side surface of the substrate. While a resulting closed space is kept in a vacuum by a vacuum pump but the opposite-side surface of the substrate relative to the electrode-side surface is in a non-vacuum, an electric field is applied to the substrate.Type: GrantFiled: July 18, 1994Date of Patent: January 14, 1997Assignee: Fuji Photo Film Co., Ltd.Inventor: Akinori Harada
