  • Publication number: 20240109330
    Abstract: A printing apparatus includes a liquid tank unit, a printing head, and a supply tube unit. The liquid tank unit includes first and second liquid tanks that store liquid and are arranged in parallel to each other. The printing head ejects liquid from the first and second tanks while moving in a main scanning direction. The supply tube unit includes a first supply tube connecting the first liquid tank to the printing head and includes a second supply tube coupled in parallel to the first supply tube and connecting the second liquid tank to the printing head. The second supply tube transitions from a connected tube state in which the second and first supply tubes are coupled in parallel to a single tube state by being separated from the first supply tube, passes across the first supply tube, and is connected to a connection port of the second liquid tank.

  • Patent number: 7817335
    Abstract: A microscope apparatus including a light source device, a storage table, and a setting controller is provided. The light source device includes a light intensity adjuster which changes light intensity of an illumination light of plural different wavelength regions selectively extracted from light emitted from a light source, and thereby emitting the illumination light including light of the plural different wavelength regions in such a manner that a light intensity ratio of light of one wavelength region to light of another wavelength region is variable. The storage table stores therein set values of the light intensity adjuster for each of combination patterns of the wavelength regions of the illumination light emitted from the light source device.

  • Patent number: 7764424
    Abstract: A wavelength selection unit includes a light source which emits light of at least a predetermined wavelength region, a collector lens which collects the light emitted from the light source and emits a parallel flux which is inclined relative to a light axis of an optical system of itself, a selective reflection optical system which reflects light of a predetermined wavelength region from the parallel flux selectively, and a returning optical system which returns each reflected flux reflected by the selective reflection optical system symmetrically about a reflected light axis of the selective reflection optical system. The collector lens collects a back flux which is returned by the returning optical system and which is re-reflected by the selective reflection optical system, and forms a light source image of the light source.

  • Publication number: 20060037669
    Abstract: A method for manufacturing a stainless steel product, which comprises contacting a bulk product of a ferritic stainless steel having been formed into a desired shape through melting with an inert gas containing nitrogen at 800° C. or higher, to thereby convert the structure of the whole or a part of the bulk product to austenite and produce an austenitic product or a product having a two-phase structure comprised of ferrite and austenite, respectively. The method allows the reduction of the manufacturing cost of a formed austenitic stainless steel product to a satisfactorily low level, which results in the manufacture of a stainless steel product having satisfactory characteristics in both of strength and corrosion resistance at a satisfactorily low cost.
