Publication number: 20240149503Abstract: A molding device includes: a lower mold that supports a workpiece containing a thermoplastic resin and that is heated to a first predetermined temperature; an upper mold that is opposed to the lower mold, that presses the workpiece, and that is heated to a second predetermined temperature; a transferer that moves the lower mold and the upper mold relative to each other in a transfer direction of the workpiece; and control circuitry. The lower mold includes temperature-controlled regions adjacent to one another in the transfer direction, the temperature-controlled regions including a first lower mold temperature-controlled region and a second lower mold temperature-controlled region having a temperature lower than a temperature of the first lower mold temperature-controlled region. The control circuitry changes proportions of the first and second lower mold temperature-controlled regions in the lower mold as a function of a relative position between the upper and lower molds.Type: ApplicationFiled: January 10, 2024Publication date: May 9, 2024Applicant: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Kenshiro OKUMURA, Takaya HAMAMOTO, Sayaka OCHI, Naoki SHIMADA, Akio KAWAMATA, Yuya OUCHI

Patent number: 8461075Abstract: The present invention relates to recording material having a laser coloring layer, wherein the laser coloring layer comprises one or more materials selected from among pigments, dyes and inorganic materials, and the laser coloring layer exhibits absorption at a wavelength within a range from 700 to 12,000 nm. The recording material of the present invention has a laser coloring layer of a desired hue, such as yellow, cyan, magenta, orange, white or black, and by conducting printing by laser irradiation, a recorded item with excellent color tone can be obtained.Type: GrantFiled: September 2, 2005Date of Patent: June 11, 2013Assignee: Toyo Ink Mfg. Co., Ltd.Inventors: Norifumi Watanabe, Yoshiyuki Onai, Jun Kaneda, Atsushi Katsuya, Kenshiro Shimada

Patent number: 8231960Abstract: The present invention provides a decorative paper which is excellent in solvent resistance, and chemical resistances such as alkali resistance, acid resistance and alcohol resistance without carrying out complicated steps such as an addition of a curing agent into a ink layer because the ink layer which is poor at solvent resistance and chemical resistance is crosslinked. The decorative sheet of the present invention comprises a base material, an ink layer, a curable primer layer containing a curing agent reactive with a resin in the ink layer, and an active energy ray-curable surface protective layer, which are provided in the order of the curable primer layer/ink layer/active energy ray-curable surface protective layer on the base material.Type: GrantFiled: July 7, 2006Date of Patent: July 31, 2012Assignees: Toyo Ink Mfg. Co., Ltd., Toppan Cosmo, Inc.Inventors: Kenshiro Shimada, Joji Suzuki, Katsuyuki Ueki
