Publication number: 20240071640Abstract: Provided is a chemical decontamination method that shortens the decomposition time of a reduction decontamination agent. An oxidization decontamination, a decomposition of an oxidization decontamination agent, and reduction decontamination using an oxalic acid aqueous solution are performed on a target piping of a BWR plant. After that, the oxalic acid is decomposed (S7). That is, a part of the oxalic acid is decomposed by irradiating the oxalic acid aqueous solution with ultraviolet rays upstream of a decomposition device (S8), and Fe3+ in the aqueous solution is converted to Fe2+. Hydrogen peroxide is supplied to the decomposition device (S9). In the decomposition device, the oxalic acid is decomposed by a catalyst and hydrogen peroxide, Fe2+ and hydrogen peroxide react to produce Fe3+ and OH*, and the oxalic acid is decomposed by OH*. A corrosion potential of the aqueous solution flowing out from the decomposition device is measured (S11).Type: ApplicationFiled: October 29, 2021Publication date: February 29, 2024Inventors: Tsuyoshi ITOU, Kazushige ISHIDA, Hideyuki HOSOKAWA, Shintaro YANAGISAWA, Takashi OOHIRA

Patent number: 8766076Abstract: A keyboard device for an electronic keyboard instrument, capable of ensuring stable contact between movable contacts and fixed contacts of a switch body, to accurately detect key depression information. A hammer has a pressure-applying surface formed in a predetermined configuration. A key switch detects key depression information and includes a substrate with fixed contacts, a hollow switch body with a pressure-receiving surface, and movable contacts provided inside the body. Pressing of the pressure-receiving surface by the pressure-applying surface sequentially brings the movable contacts into contact with the fixed contacts, causing switch body compressive deformation. The pressure-receiving surface and pressure-applying surface are complementary in shape, and an orientation of the former conforms to an orientation of the latter when hammer pivotal motion is terminated after the movable contacts are brought into contact with the fixed contacts.Type: GrantFiled: January 11, 2011Date of Patent: July 1, 2014Assignee: Kabushiki Kaisha Kawai Gakki SeisakushoInventor: Hideyuki Ishida

Publication number: 20100165659Abstract: A planar light guide includes recesses formed in the upper and lower surfaces thereof. The recesses in the lower surface are perpendicular to the recesses in the upper surface. In a state in which light sources emit light into the planar light guide, when an X-direction driving mechanism is driven and the planar light guide is deformed in the X directions, the recesses in the upper surface are opened, so that the lower surface side can perform surface emission of light. When a Y-direction driving mechanism is driven and the planar light guide is deformed in the Y directions, the recesses in the lower surface are opened, so that the upper surface side can perform surface emission of light. By selectively driving the X-direction driving mechanism or the Y-direction driving mechanism, the position from which light is output, the amount of light, or the direction of light can be changed.Type: ApplicationFiled: March 12, 2010Publication date: July 1, 2010Applicant: ALPS ELECTRIC CO., LTD.Inventors: Kazutaka ISE, Hideyuki ISHIDA

Publication number: 20100026632Abstract: A reflective display portion includes indication and background portions. A first reflective layer is formed on the indication portion, and a second reflective layer is formed on the background portion on an outer surface of a translucent sheet. Each of the indication and the background portions has a different reflectance value. A light limiting layer is formed on an inner surface of the sheet at an inner side of the second reflective layer so as to reduce a difference of a light transmittance between the indication portion and the background portion. When the external light reflects, the indication portion and the background portion of the reflective display portion are observable owing to the difference of the light reflectance. The light from the light emitting display portion transmits the indication and background portions such that the display content of the light emitting display portion is observable.Type: ApplicationFiled: October 9, 2009Publication date: February 4, 2010Applicant: ALPS ELECTRIC CO., LTD.Inventors: Hideyuki ISHIDA, Masami AIHARA, Tsuyoshi HAYAMA, Naoki ITO
