Publication number: 20240069280Abstract: A photodetector includes a substrate, a material layer, a first electrode made of a metal, a core, a second electrode and a light absorption layer made of graphene. The first electrode, the core, and the material layer constitute a hybrid plasmonic waveguide, and the light absorption layer is disposed thereon. Light guided in the hybrid plasmonic waveguide is absorbed by the light absorption layer, photoelectrically converted by the PTE effect, and extracted as an electric signal from the first electrode and the second electrode.Type: ApplicationFiled: February 8, 2021Publication date: February 29, 2024Inventors: Masaaki Ono, Katsumasa Yoshioka, Kengo Nozaki, Akihiko Shinya, Masaya Notomi

Patent number: 8214071Abstract: A method includes steps of: expressing changes of velocity components of a paper material at an exit of a slice lip by using a mathematical model, wherein the changes of velocity components are caused by manipulating an edge flow adjustment means (or a side bleed adjustment means) of a headbox when supplying the paper material on a wire; without changing a velocity component of a flow of the paper material in the mathematical model, setting the mathematical model based on an assumption in which a velocity component orthogonally crossing a flow direction of the paper material is proportionally changed by changes of an edge flow (or a side bleed) of a certain response width from the exit of the slice lip; and conducting a forecasting calculation of changes of a fiber orientation profile in a cross direction by using the mathematical model.Type: GrantFiled: September 4, 2007Date of Patent: July 3, 2012Assignees: Yokogawa Electric Corporation, Nippon Paper Industries Co., Ltd.Inventors: Takashi Sasaki, Hirofumi Sano, Katsumasa Ono, Hidenobu Todoroki

Patent number: 7699960Abstract: Methods for producing cast-coated papers showing a reduced level of curling and reduced curling or wavy deformation caused by moisture absorption or other reasons as well as showing a high surface quality in the cast-coated surface. The steps for producing cast-coated papers include applying a coating color based on a pigment and an adhesive on one side of a base paper, and pressing/drying the coated layer in the wet state against a casting drum mirror surface, where moisture is added to the coated paper by passing it through conditioned air at a high temperature and a high humidity (for 20 seconds or more) after pressing/drying the coated layer against a casting drum.Type: GrantFiled: March 31, 2004Date of Patent: April 20, 2010Assignee: Nippon Paper Industries Co., Ltd.Inventors: Katsumasa Ono, Hidenobu Todoroki, Yuji Abe

Patent number: 7611606Abstract: The present invention provides a low-density neutral paper offering excellent opacity, opacity after printing and other advantageous printability properties despite high bulk, by containing, as a filler, precipitated calcium carbonate-silica composite having an average particle size of 30 ?m or less and produced by neutralizing a mixture of precipitated calcium carbonate and alkaline silicate to pH 7 to 9, wherein the ratio of precipitated calcium carbonate to silica (precipitated calcium carbonate/silica) is 30/70 to 70/30 in solid content by weight and the surface of precipitated calcium carbonate particles is covered with silica. In particular, the present invention provides a low-density printing paper, or an electrophotographic transfer paper offering excellent stiffness and copier suitability, by means of adjusting the filler content in paper to a range of 1 to 25 solid content percent by weight, or provides a neutral newsprinting paper by means of adjusting the filler content in paper to a range of 0.Type: GrantFiled: March 15, 2005Date of Patent: November 3, 2009Assignee: Nippon Paper Industries Co., Ltd.Inventors: Kazunari Soga, Dai Nagahara, Kazuyuki Fujita, Takashi Ochi, Koji Kutsuwa, Katsumasa Ono
