Patent number: 11935559Abstract: This magnetic disk device is a 3.5-inch magnetic disk device equipped with magnetic disks formed from an aluminum alloy substrate. The magnetic disks arranged in a stacked manner have a thickness Td of 0.3 mm to 0.6 mm, the number N of magnetic disks involved is 10 to 16, and spacers disposed between the magnetic disks have an outside diameter 2 Rso of 35 mm to 65 mm. The outside diameter 2 Rso (mm) of the spacers satisfies 2 Rso??60 Td+70 and 2 Rso??0.5 N2?+16.5 N?73.Type: GrantFiled: November 11, 2021Date of Patent: March 19, 2024Assignees: UACJ CORPORATION, FURUKAWA ELECTRIC CO., LTD.Inventors: Naoki Kitamura, Kotaro Kitawaki, Hideyuki Hatakeyama, Ryohei Yamada, Toshihiro Nakamura

Patent number: 10966618Abstract: A light-emitting section (21) emits light to be irradiated on a body of a patient (100). A light-receiving section (22) outputs a signal corresponding to an intensity of light which has been transmitted through or reflected from the body of the patient (100). A pulse-amplitude Index acquiring section (32) analyzes amplitude of the signal to acquire a pulse-amplitude Index of the patient (100). A pulse determining section (33) determines presence or absence of a pulse of the patient (100) in accordance with the pulse-amplitude Index. A notifying section (34) notifies a result of determination made by the pulse determining section (33).Type: GrantFiled: July 13, 2016Date of Patent: April 6, 2021Assignees: NIHON KOHDEN CORPORATION, KYOTO UNIVERSITYInventors: Tomoyoshi Natsui, Satoshi Hayashi, Tsutomu Wakabayashi, Taku Iwami, Toshihiro Hatakeyama, Tetsuro Nishimura, Takayuki Otani

Patent number: 7452219Abstract: A flat earth terminal in the shape of a flat plate includes a main part with a screw insertion hole and a leg-like terminal part continuously extending from an end of the main part. A recess is formed on a mounting side of the flat earth terminal intended to be located on a printed circuit board, in a proximal portion of the terminal part continuously extending from the main part, to separate a distal portion of the terminal part from the main part. By this, solder is prevented from flowing from the terminal part to the main part, with certainty, so that a stable electric connection between the main part and the printed circuit board is ensured.Type: GrantFiled: February 14, 2007Date of Patent: November 18, 2008Assignee: Kyoshin Kogyo Co., Ltd.Inventors: Yoshikazu Kitajima, Toshihiro Hatakeyama

Patent number: 7094076Abstract: A ground terminal mountable to a peripheral portion of a printed board, which includes a ground terminal body having a pick-up portion picked up by a mounter and a first end edge portion formed with a semicircular notch, and which includes a connection portion formed in, for example, a second end edge portion of the ground terminal body. To mount the ground terminal to a printed board having a first side edge portion formed with a mounting hole having a function of a positioning hole, the printed board is positioned at a part mounting position with its first and second side edge portions individually engaged with first and second guide rails, and the mounter is operated to place the ground terminal on the printed board, with the notch directed to the first guide rail and aligned with the mounting hole.Type: GrantFiled: March 11, 2004Date of Patent: August 22, 2006Assignee: Kyoshin Kogyo Co., Ltd.Inventor: Toshihiro Hatakeyama

Patent number: 7044755Abstract: A ground terminal capable of being downsized and having good electrical connectability with a chassis. The ground terminal includes a ground terminal body formed into an annular shape as viewed in plan, and at least one connection portion formed integrally with the ground terminal body, the connection portion being bendable and extending from an inner circumference of the ground terminal body toward the center of the ground terminal. When a mounting screw used to mount a printed board mounted with the ground terminal to a chassis is inserted into the annular ground terminal body and a mounting hole of the printed board, the connection portion of the ground terminal is bent in the mounting hole to be brought in contact with the chassis.Type: GrantFiled: March 22, 2004Date of Patent: May 16, 2006Assignee: Kyoshin Kogyo Co., Ltd.Inventor: Toshihiro Hatakeyama

Patent number: 6056585Abstract: A quick connector includes a contact and a housing fitted thereon. The contact has a first contact piece, a second contact piece which cooperates with the first contact piece to hold a core wire of an electric wire, and leg portions which are electrically connected and mechanically fixed to a circuit board. The housing has a top wall thereof formed with a core-wire insertion hole and rod insertion holes, and a peripheral wall thereof defining therein an accommodation space in which the first and second contact pieces are closely received. The quick connector permits easy insertion of an electric wire thereinto, and adequately maintains electrical connection between itself and an electric wire inserted thereinto. The holding of the electric wire can be released by inserting a releasing rod into either one of the rod insertion holes. The quick connector is suitable to be automatically installed onto a circuit board.Type: GrantFiled: May 13, 1998Date of Patent: May 2, 2000Assignee: Kyoshin Kogyo Co., Ltd.Inventors: Toshihiro Hatakeyama, Iwao Nishimura, Koji Ito
