  • Patent number: 6494627
    Abstract: 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.

  • Publication number: 20020171018
    Abstract: The cup holder includes a case and a holder main body. The holder main body includes a bottom wall, a rear opening, a cup mounting member, and a forcing device. The cup mounting member has a rear plate which closes the rear opening in the retracted position, and a mounting plate which closes the bottom opening in the retracted position and aligns vertically with the bottom wall in the forward position. The case has a pressing part which in the stored position presses the cup mounting member toward the forward position in opposition to the force of the forcing device. The holder main body can be stored inside the case without obstruction to a device positioned inside the case.

  • Publication number: 20020170987
    Abstract: 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.

  • Publication number: 20020015595
    Abstract: 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.

  • Publication number: 20010055491
    Abstract: 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.

  • Patent number: 6264264
    Abstract: In a rotary damper device and a sun visor attaching apparatus using the same, a damping force works in one way. The rotary damper device includes a case, a rotor and a viscous fluid. The rotor is rotatably held in the case and connected to a shaft. The viscous fluid is sealed in the case. The rotor includes a rotary vane, a through-hole passing through the vane, and a valve. The rotary vane is used to agitate the viscous fluid. The valve opens the through-hole when the shaft is rotated in one direction and closes the through-hole when the shaft is rotated in the other direction.

  • Publication number: 20010003032
    Abstract: 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.

  • Patent number: 6028869
    Abstract: A polarization control element for controlling the direction of polarization and the longitudinal mode of a laser is formed by cutting a birefringent crystal so that its light incident face and light emanating face are at an angle to the optical axis of the crystal and adjusting the thickness and the reflectivities of the faces of the crystal so that the crystal can function as a Fabry-Perot etalon. The thickness of the birefringent crystal is set so that the wavelengths selected by the birefringent crystal for two laser oscillation modes whose directions of polarization are normal to each other differ from each other.

  • Patent number: 5744073
    Abstract: 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.

  • Patent number: 5652757
    Abstract: 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.

  • Patent number: 5594746
    Abstract: 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.
