| 20090148787 | Method for fluorescent image formation, print produced thereby and thermal transfer sheet thereof - The present invention relates to a method for fluorescent image formation which can form a highly scratch-resistant fluorescent full-color image using a colorless fluorescent agent and can freely regulate the tone of color mixture of a combination of two or more fluorescent colors in order to impart, to articles, a higher level of forgery preventive function than a prior art technique and a print having a high level of forgery preventive function. The invention characterized in that fluorescent inks are provided that are substantially colorless upon visible light irradiation and contain organic fluorescent agents which, upon ultraviolet light irradiation, emit fluorescences in a visible region, and that two or more fluorescent inks, which emit fluorescences having mutually different color tones, are deposited on a printing face in its image formation region according to information on an image to be printed in a dot matrix manner so that dots of one color do not overlap with dots of another color. | 06-11-2009 |
| 20090219592 | FABRICATION PROCESS FOR CHOLESTERIC LIQUID CRYSTAL MEDIA HAVING A VOLUME HOLOGRAM - The invention provides a process capable of fabricating a cholesteric liquid crystal medium having a volume hologram with efficiency yet without recourse to complicated steps such as an alignment step. This is achievable as follows. A volume hologram layer is formed on a substrate, and a cholesteric liquid crystal layer is then formed on another substrate comprising a center substrate film that is subjected to bondable treatment. The volume hologram layer is applied to the center substrate film that is subjected to bondable treatment, and placed in a state where the volume hologram layer and cholesteric liquid crystal layer are laminated together via the substrate. The substrate is peeled off the volume hologram layer, and an adhesive layer is formed on the surface of the volume hologram layer off which the substrate is peeled off, followed by the provision of the substrate on the adhesive layer. Finally, the multilayer structure is shaped into a label form of cholesteric liquid crystal medium having a volume hologram layer. | 09-03-2009 |
| 20100197016 | Structure enclosing hematopoietic progenitor cells from ES cells and method for preparing blood cells using the same - An object of the present invention is to provide a sac-like structure enclosing hematopoietic progenitor cells and a method for preparing the sac-like structure as well as a method for efficiently preparing blood cells such as mature megakaryocytes and platelets from the sac-like structure. The present invention provides a sac-like structure enclosing hematopoietic progenitor cells, the sac-like structure being obtained by plating ES cells onto feeder cells and culturing the ES cells under suitable conditions for inducing hematopoietic progenitor cell differentiation. Moreover, the present invention provides a method for producing various blood cells, the method comprising further culturing hematopoietic progenitor cells enclosed in the sac-like structure under suitable conditions for inducing blood cell differentiation. | 08-05-2010 |
| 20110053267 | METHOD FOR PREPARATION OF PLATELET FROM iPS CELL - It is an object of the present invention to provide a method for efficiently preparing blood cells, such as mature megakaryocytes and platelets, from iPS cells in an in vitro culture system. | 03-03-2011 |

| 20080299464 | LENGTHY VOLUME HOLOGRAM LAYER TRANSFER FOIL, METHOD OF PRODUCING VOLUME HOLOGRAM LAMINATE USING THE SAME AND VOLUME HOLOGRAM LAMINATE - The present invention provides a lengthy volume hologram layer transfer foil capable of transferring a volume hologram layer continuously to a specified position of a transfer-receiving member. The above problem can be solved by a lengthy volume hologram layer transfer foil according to the present invention, the transfer foil is formed lengthwise and comprises: a substrate, a volume hologram layer which is formed on the substrate and in which a volume hologram is recorded, and a heat seal layer which is formed on the volume hologram layer and which contains a thermoplastic resin, the transfer foil being characterized in that it is provided with a cut portion formed so as to penetrate through the heat seal layer and to cut at least a part of the volume hologram layer, on at least a part of the full width in a direction perpendicular to the longitudinal direction thereof. | 12-04-2008 |
| 20080316556 | VOLUME HOLOGRAM TRANSFER FOIL, VOLUME HOLOGRAM LAMINATE, AND PRODUCTION METHOD THEREOF - A major object of the present invention is to provide a volume hologram transfer foil that gives a volume hologram laminate higher in antiforgery function, | 12-25-2008 |
| 20100104952 | METHOD OF PRODUCING VOLUME HOLOGRAM LAMINATE - A method of producing a volume hologram laminate which can regenerate a hologram image in an arbitrary wavelength by a simple process. The method uses a volume hologram forming substrate which includes: a substrate, a volume hologram layer formed on the substrate and containing a photopolymerizable material, a resin layer, formed on the substrate so as to contact to the volume hologram layer, containing a resin and a polymerizable compound. The producing method includes processes of: a hologram recording process to record a volume hologram to the volume hologram layer, a substance transit process of transiting the polymerizable compound to the volume hologram layer, and an after-treatment process of polymerizing the polymerizable compound. | 04-29-2010 |
