Publication number: 20240099889Abstract: The control unit executes an irradiation plan acquisition step and a spot interval guide display step. At the irradiation plan acquisition step, the control unit acquires an irradiation plan for irradiating a patient's eye with treatment laser light using a contact lens having a reflective surface that reflects the treatment laser light in a direction intersecting the optical axis. At the spot interval guide display step, the control unit controls the internal display unit to display a spot interval guide indicative of an appropriate interval between a plurality of irradiation spots in accordance with the progress of the irradiation plan. The plurality of irradiation spots are scheduled to be irradiated with the laser light.Type: ApplicationFiled: September 26, 2023Publication date: March 28, 2024Inventors: Takanori TSUMURA, Naoki ICHIKAWA, Kohei MASUNAGA, Shota MIZUTA, Teruki TSUKAMOTO

Patent number: 11768226Abstract: Provided are an inspection jig and an inspection apparatus in which a configuration for bending a plurality of contacts in the same direction can be simplified. The inspection jig includes a plurality of contacts each of which has a rod shape, a first support portion that supports the first end portion side of the plurality of contacts, and a second support portion that supports the second end portion side of the plurality of contacts. The first support portion includes a facing support plate that is disposed to face the second support portion in a manner separated from the second support portion and has a plurality of through holes through which the plurality of contacts are inserted, and a cross section of each of the through holes has an elliptical shape whose major axis extends in a predetermined specific direction along a plane direction of the facing support plate.Type: GrantFiled: July 28, 2021Date of Patent: September 26, 2023Assignee: NIDEC READ CORPORATIONInventors: Kohei Tsumura, Takanori Furukawa, Jyun Yamanouchi

Publication number: 20230138341Abstract: An inspection jig includes a rod-shaped probe, a first support portion that supports one end portion side of the probe, a second support portion that supports the other end portion side of the probe, and a separation holding member that holds the first support portion and the second support portion to be separated from each other. The first support portion includes a support plate in which a through hole through which the probe is inserted is formed. A reinforcing plate having bending strength stronger than that of the support plate is disposed on a surface of the support plate facing the second support portion.Type: ApplicationFiled: April 19, 2021Publication date: May 4, 2023Inventors: Kohei TSUMURA, Hidekazu YAMAZAKI

Publication number: 20230127957Abstract: A circuit board inspection apparatus includes an inspection processing portion that inspects an electric circuit of a board to be inspected, an inspection jig, and a position detector used to position the inspection processing portion relative to the board to be inspected. The inspection jig includes a probe unit having a probe, a first board, a second board located in parallel with the first board in a thickness direction of the first board, an electrical connection portion that electrically connects the first board and the second board, and a second board holding portion that holds the second board from the first board and holds the probe unit on a side opposite to the first board side. The second board holding portion has a position detection opening penetrating in the thickness direction, at a position overlapping the position detector as viewed from the thickness direction of the second board holding portion.Type: ApplicationFiled: February 22, 2021Publication date: April 27, 2023Inventor: Kohei TSUMURA

Publication number: 20230117705Abstract: An inspection jig includes a first board, a probe unit including a probe, a second board located in parallel with the first board and electrically connected to the probe, an electrical connection portion electrically connecting the first board and the second board, and a board holding portion holding the second board in parallel with the first board in the thickness direction and holding the probe unit. The board holding portion includes a probe-side holding plate located on the probe unit side of the second board and a holding plate support portion that positions the probe-side holding plate at a position where the probe-side holding plate is in parallel with the first board in the thickness direction. The board holding portion holds the second board so that the first board and the second board are electrically connected via the electrical connection portion being sandwiched between the first board and second board.Type: ApplicationFiled: February 22, 2021Publication date: April 20, 2023Inventor: Kohei TSUMURA
