Patent number: 11697234Abstract: Provided is a decorative sheet in which a graphic is less deteriorated even after injection molding. First and second graphic layers contain a plurality of interference pigments that emit respective interference lights having respective colors in a first direction in first and second binders to exhibit first and second mixed colors. An optical functional layer changes a reflectance property of light. The first and second graphic layers represent a graphic visually recognizable from a front surface of a decorative sheet and allow visually recognizing an image displayed on a back surface from the front surface. The optical functional layer increases at least one of ratios of an amount of visible light representing the graphic and an amount of visible light representing the image that transmits through the first and second graphic layers to an amount of visible light reflected by and visible on the front surface.Type: GrantFiled: August 3, 2020Date of Patent: July 11, 2023Assignee: NISSHA CO., LTD.Inventors: Daichi Hama, Chuzo Taniguchi, Toshitsugu Fujimura, Masato Kurahashi

Publication number: 20230054589Abstract: A molded body is molded into a prescribed three-dimensional shape. A protective film covers at least a portion of a surface of the molded body. A circuit film is integrally molded with the molded body. An electric circuit is installed in the circuit film and causes a physical change outside of a molded article or causes an electric signal to be generated in accordance with a physical change outside of the molded article. The protective film or the circuit film has a contact area disposed on the surface of a contact portion. The molded body includes a hot melt adhesive: which is disposed on the surface of the molded body which is opposite skin, with the contact area therebetween; and which defines a three-dimensional shape of the contact area within the prescribed shape. The hot melt adhesive covers at least a portion of the circuit film.Type: ApplicationFiled: January 27, 2021Publication date: February 23, 2023Applicant: NISSHA CO.,LTD.Inventors: Chuzo TANIGUCHI, Ryomei OMOTE, Eiji KAWASHIMA, Jun SASAKI, Yoshihiro SAKATA, Toshitsugu FUJIMURA

Patent number: 10418202Abstract: A method for manufacturing a membrane switch member that can be manufactured easily and that can be caused to function as an electrostatic sensor even when a protruding portion is pressed. Injection molding by injecting a material including a supercritical fluid gas and a resin material in a mixed state; and, after the injection molding, removing a first mold from a second mold, causing gas produced within the injection molded resin to grow in concave portions, thereby causing the concave portions to invert to a protruding state; and manufacturing a membrane switch member in which voids are formed between the protruding portions and a molding resin layer, and portions other than the portions corresponding to the protruding portions are adhered to the resin layer by an adhesion layer.Type: GrantFiled: April 28, 2016Date of Patent: September 17, 2019Assignee: NISSHA PRINTING CO., LTD.Inventors: Chuzo Taniguchi, Masayuki Kyoumen, Toshitsugu Fujimura, Takenori Yoshida, Isao Yamamoto

Patent number: 7922952Abstract: In the simultaneous molding and decorating method for forming an image onto the surface of a resin molding simultaneously with resin molding by holding a decoration sheet on which the image is rotary printed in a die, such a decoration sheet as having a predetermined pattern for every revolution of the cylinder of a printing machine wherein the image is formed in the longitudinal direction at a constant interval is used. By holding the decoration sheet longer than one revolution but shorter than two revolutions of that in the die and performing resin molding, the image is formed onto the surface of a long molding exceeding the outer circumference of the cylinder.Type: GrantFiled: October 3, 2008Date of Patent: April 12, 2011Assignee: Nissha Printing Co., Ltd.Inventor: Toshitsugu Fujimura

Publication number: 20100028475Abstract: A compression molding method capable of preventing contamination of abrasion powders generated by scoring to thereby improve the product yield is provided. The compression molding method, including a fixed mold and a movable mold arranged opposite each other, includes: contacting a slide board connected with a movable die plate on the movable mold side via a spring, with the parting face of the fixed mold by a spring force; further advancing the movable mold after injecting resin into a cavity in the mold, and compressing and molding the resin filled in the cavity by a core, provided in the movable mold, penetrating through the slide board. A resin film is disposed between the fixed mold and the slide board, and one surface of the resin in the cavity is compressed by the core via the resin film.Type: ApplicationFiled: September 10, 2009Publication date: February 4, 2010Inventors: Shinya Takeuchi, Toshitsugu Fujimura
