Publication number: 20240131832Abstract: Provided is a method for manufacturing a laminate that is excellent in adhesion between the copper foil and the resin film while using a polyvinyl acetal resin having low reactivity with the copper foil. This method includes the steps of providing a copper foil having on at least one side a treated surface on which an amount of metal components is 30 atomic % or more and 40 atomic % or less, and attaching or forming a polyvinyl acetal resin film on the treated surface of the copper foil to form a laminate. The amount of metal components is a proportion of Cr, Ni, Cu, Zn, Mo, Co, W, and Fe in a total amount of N, O, Si, P, S, Cl, Cr, Ni, Cu, Zn, Mo, Co, W, and Fe when the treated surface is subjected to elemental analysis by X-ray photoelectron spectroscopy (XPS).Type: ApplicationFiled: February 8, 2022Publication date: April 25, 2024Applicant: MITSUI MINING & SMELTING CO., LTD.Inventors: Hiroto IIDA, Makoto HOSOKAWA, Misato MIZOGUCHI, Shinya HIRAOKA, Toshiyuki SHIMIZU

Publication number: 20240132229Abstract: An aircraft light is provided which can illuminate an illuminated area with appropriate levels of illuminance. An aircraft light is configured, including: at least one or more light-emitting elements as light sources; and an inner lens configured to project light emitted from the light-emitting elements onto a desired area, in which the inner lens has a lens that splits light of a single light-emitting element in different directions. According to this aspect, both a far illumination area and a near illumination area can be illuminated, and the luminous intensity can also be adjusted by adjusting the amount of a beam to be split; therefore, an illuminated area can be illuminated with appropriate levels of illuminance.Type: ApplicationFiled: February 17, 2022Publication date: April 25, 2024Inventors: Hiroto SHIMIZU, Kenichi SHIMIZU

Patent number: 9279563Abstract: Provided is a lamp configured to control an irradiation angle. The lamp includes a light emitting unit that is provided with an LED and a reflector having a reflecting surface that reflects light from the LED. The reflecting surface of the reflector is formed to have a parabolic shape in a cross-section perpendicular to an optical axis of the LED. The reflecting surface of the reflector is formed to have an elliptical shape in a cross-section parallel to the optical axis of the LED so as to condense and diffuse reflected light beams in a forward direction.Type: GrantFiled: October 23, 2013Date of Patent: March 8, 2016Assignee: Koito Manufacturing Co., Ltd.Inventors: Shigeo Sawada, Hiroto Shimizu, Tomoya Nishihara

Patent number: 5553172Abstract: An electronic image pickup apparatus picks up an object image such as an image on a blackboard and outputs the image. The apparatus can synthesize a picked-up image with format data input from another unit and output the synthesized image. When synthesis processing is to be performed, format data to be synthesized are created and stored in several line buffers in advance. When a picked-up one-line image signal is written in a line buffer of 1 line, the format data stored in the several line buffers are read out, and the image signal and the format data are synthesized in the line buffer of 1 line. By outputting the data in this line buffer in units of lines, the synthesized data obtained by synthesizing the picked-up image with the format data is output.Type: GrantFiled: November 29, 1994Date of Patent: September 3, 1996Assignee: Casio Computer Co., Ltd.Inventors: Satoshi Kimura, Hideki Miyazaki, Hiroto Shimizu, Kazuto Yamamoto, Tsuyoshi Kato

Patent number: 5450127Abstract: An image pickup apparatus includes an optical system for forming an image of an object. An image pickup section effects the image pickup operation by causing a one-dimensional image pickup device to scan an image formed by the optical system. A light exposure detecting section detects light exposure based on a luminance signal output according to the scanning operation of the one-dimensional image pickup device at the light exposure detection time. A control section controls the image pickup section according to the light exposure detected by the light exposure detecting section at the time of image pickup operation.Type: GrantFiled: December 21, 1994Date of Patent: September 12, 1995Assignee: Casio Computer Co., Ltd.Inventors: Hiroto Shimizu, Yoshimasa Yokoyama
