Patent number: 11970644Abstract: Provided is a method for peeling a PSA sheet adhered on a polarizing plate. The PSA sheet has a PSA layer. The PSA layer includes a layer A forming at least one surface of the PSA layer. Of the polarizing plate, the surface to which the PSA sheet is adhered is corona-treated or plasma-treated. The peeling method includes a water-peel step in which the PSA sheet is peeled from the polarizing plate, in a state where an aqueous liquid exits at the interface between the polarizing plate and the PSA sheet at the front line of peeling the PSA sheet from the polarizing plate, with the aqueous liquid allowed to further enter the interface following the movement of the peel front line.Type: GrantFiled: January 28, 2019Date of Patent: April 30, 2024Assignee: NITTO DENKO CORPORATIONInventors: Naofumi Kosaka, Yosuke Shimizu, Satoshi Honda, Taiki Shimokuri, Shou Takarada, Masayuki Satake, Kenichi Okada, Atsushi Takashima, Ginji Mizuhara

Patent number: 6929575Abstract: A pulley comprises a disk and an insert. The insert is fitted into the center of the disk integrally. Linear expansion coefficient of the disk is larger than the same of the insert. A concavity is formed on a periphery surface of the insert so that both side surfaces of the concavity are slanted outwardly, i.e. a distance between the side surfaces become large in proportion to being far from the centerline of the insert. When a slanting angle is defined as an angle between the side surface and a line which is perpendicular to the centerline of the insert on a plane including the centerline of the insert, the slanting angle is set from ten degrees to forty-five degrees, preferably from fifteen degrees to forty-five degrees. The disk is made of synthetic resin such as phenol resin, and the insert is made of metal such as iron.Type: GrantFiled: March 25, 2003Date of Patent: August 16, 2005Assignee: Toyoda Koki Kabushiki KaishaInventors: Hiroyuki Takahashi, Atsushi Kosaka

Patent number: 6926253Abstract: An air passage in an air-conditioner such as an automotive air-conditioner is selectively opened or closed by moving a position of an opening formed on a film screen relative to the air passage. The film screen is coupled to a pair of rollers, forming a curved path between the pair of rollers guided by a guiding surface. The film screen is formed by laminating a first film made of resin and a second film made of woven fabric having a higher elongation rate for a temperature rise than the first film. The second film is positioned inside of the curved path to prevent a shape of the roller or the guiding surface from being easily transferred to the film screen.Type: GrantFiled: November 17, 2003Date of Patent: August 9, 2005Assignee: DENSO CorporationInventors: Takahiro Tokunaga, Koji Ito, Atsushi Kosaka

Patent number: 6619071Abstract: In an adsorption-type refrigerating apparatus, an adsorber includes therein an adsorbent having a temperature-dependent characteristic in which an amount adsorbed in an adsorption step is larger than an amount adsorbed in a desorption step, even when a vapor pressure rate in the adsorption step is equal to or lower than a vapor pressure rate in the desorption step. Therefore, even when the cooling temperature of outside air for cooling the adsorbent increases, a sufficient cooling capacity can be obtained. In addition, a difference between the amount adsorbed in the adsorption step and the amount adsorbed in the desorption step can be made larger.Type: GrantFiled: June 6, 2002Date of Patent: September 16, 2003Assignee: Denso CorporationInventors: Hideaki Sato, Katsuya Ishii, Atsushi Kosaka, Shigeo Numazawa, Seiji Inoue, Kouji Inagaki, Kazuhisa Yano, Norihiko Setoyama, Yoshiaki Fukuyama
