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: 11933489Abstract: An optical device includes a metal reflective layer substantially made of a metal material, a first light transmissive layer disposed on the metal reflective layer, an optical multilayer reflective film disposed on the first light transmissive layer and including a plurality of sublayers stacked on each other and having different refractive indexes, and a wavelength converting layer disposed on the optical multilayer reflective film and containing a fluorescent material capable of absorbing incident excitation light and generating fluorescent light having a lower energy. The wavelength converting layer is capable of generating mixed light containing the excitation light and the fluorescent light in response to irradiation with the excitation light.Type: GrantFiled: February 5, 2021Date of Patent: March 19, 2024Assignee: STANLEY ELECTRIC CO., LTD.Inventors: Yusuke Yokobayashi, Yasuyuki Kawakami, Yosuke Maemura, Hideaki Yamamoto, Keijiro Takashima, Ryosuke Kamakura

Publication number: 20210221015Abstract: There is provided a blade with high safety and ease, which is suitable for use with a cutter knife, as an item before step-up to an ordinary cutter knife used by an adult. In the blade of the present invention, almost all portion of a cutting edge which actually cuts an object is covered with a cover member, such that safety during handling the same is significantly high. Further, even when a blade body is made of metal, a cover member made from resin would reduce metal portion visible from outside, and thus reducing fear at a look.Type: ApplicationFiled: July 13, 2018Publication date: July 22, 2021Inventor: Yosuke TAKASHIMA

Publication number: 20210187763Abstract: A safety utility knife includes a resin-made grip part, a blade projecting from the grip part, and a resin-made head part arranged at a tip of the projecting blade. The blade is formed with a through-hole so that a resin-made coupling part lying within the through-hole couples together the grip part and the head part that are made of resin. Since the safety utility knife of the present invention allows the three resin-made parts to be joined together, it can be manufactured easily and at low cost using a 1-gate type mold. Also, there is no unnecessary increase in the blade thickness, preventing an increased cutting resistance and a rough cut end from occurring.Type: ApplicationFiled: May 30, 2019Publication date: June 24, 2021Inventor: Yosuke TAKASHIMA

Patent number: 10279489Abstract: The present invention provides a cutter knife, which even if made with only the metal parts, smoothness of sliding operation of the blade is not degraded in time, even without lubricating oil nor friction resistant coating, A slider of the cutter knife carries rolling member, which is made rolling contact with the outer surface of the cutter knife. Further, the slider has a protrusion which extends into the cutter knife body and is engaged into a hole formed on the blade. Since an external force applied onto the slider is received by the rolling member, the slider can be operated smoothly. Besides, the height of the protrusion is determined, such that the protrusion does not touch the inner surface of the cutter knife. Thus, the protrusion tip never interfere with the inner surface of the cutter knife, thereby the sliding operation of the slider would not be prevented.Type: GrantFiled: May 9, 2016Date of Patent: May 7, 2019Assignee: OLFA CORPORATIONInventors: Toshiyuki Watanabe, Minoru Masuda, Yosuke Takashima

Patent number: 8727195Abstract: Disclosed is a blade snap-off holder which enables a safe, easy and smooth operation for snapping off a blade tip of a cutter knife. The holder has an insertion opening on its wall. A tip of a knife blade inserted through the opening is received in a groove of a rotary member located inside the holder. The rotation axis of the rotary member extends substantially parallel to the score of the knife blade. When the rotary member is rotated and a bending force is applied to the tip of the knife blade, the blade tip received in the groove of the rotary member can be snapped off. A user only grasps this holder in one hand and rotates the operation lever with a finger, and then a blade tip can be snapped off cleanly and easily without any subtle control of a force.Type: GrantFiled: January 30, 2012Date of Patent: May 20, 2014Assignee: Olfa CorporationInventor: Yosuke Takashima

Patent number: 5278919Abstract: An image area determining apparatus acquires a multi-value image to determine to which one of a picture area and a character area an image signal of the multi-value image belongs. A density detecting unit detects whether or not a density value of the multi-value image is within a range between two preset density threshold values. A density variation amount detecting unit detects whether or not a variation amount of the density value of the multi-value image is less than a preset density variation threshold value. The determining apparatus determines that the multi-value image is related to a picture area when the density value of the received multi-value image is within the range between the two density threshold values and the density value variation amount of the multi-value image is less than the density variation threshold value.Type: GrantFiled: February 27, 1992Date of Patent: January 11, 1994Assignee: NEC CorporationInventors: Masashi Sugiura, Yosuke Takashima

Patent number: 4701806Abstract: An adaptive pseudo halftone generator which achieves high resolution and faithful rendering of gray scales or gradations even when video image data comprise a mixture of alphanumeric characters and other symbols represented by two-level signals and photographs and like images represented by multi-level signals. A value indicative of a degree of continuity of tones of an input video signal is computed to control the threshold value adapted for dot pattern representation on the basis of the computed value.Type: GrantFiled: February 20, 1985Date of Patent: October 20, 1987Assignee: NEC CorporationInventor: Yosuke Takashima
