Publication number: 20240304395Abstract: The present disclosure provides an electrolytic capacitor for middle or high voltage application of 160 V or more, which can suppress the total amount of gas generated inside the electrolytic capacitor. An electrolytic capacitor includes anode foil on which dielectric oxide film is formed, and a cathode body. The cathode body includes cathode foil formed of valve action metal and a carbon layer formed on the cathode foil. The anode foil and the cathode body have capacitance so that when capacitance X of the anode foil per unit area is 1, ratio of capacitance Y of the cathode body per the same unit area is equal to or more than 10.Type: ApplicationFiled: January 26, 2022Publication date: September 12, 2024Inventors: Kazuhiro NAGAHARA, Tatsuru HATAE, Kazuya KOSEKI, Atsushi YOSHIDA, Makoto TOMINAGA, Riho Gumilar MAEDA

Patent number: 10792720Abstract: A hemming device includes an anvil for placing a work, a presser material handling portion, a conveyance robot, and a roller hemming robot. The anvil includes an anvil main body portion, a positioning device, a gripping device, and a device-side ATC device to be attached to and detached from a conveyance-robot side ATC device. The presser material handling portion includes a frame portion having a shape corresponding to a shape of the work, a positioning device, a gripping device, a presser provided to press the inner panel at a position at which the presser does not interfere with a final shape, and a device-side ATC device to be attached to and detached from the conveyance-robot side ATC device. With this configuration, processing time is reduced and replacement operation of the anvil is simplified, and therefore productivity is improved.Type: GrantFiled: June 16, 2017Date of Patent: October 6, 2020Assignee: HIROTEC CORPORATIONInventors: Kohei Horike, Makoto Tominaga

Patent number: 7575408Abstract: Plural wok pairs composed of a plurality of works are stored in work storing means. A movable sensor 45 fitted to a conveyance robot 5 detects the position of one of the work pairs in the work storing means, and the work gripping means 25 takes out a plurality of works at one time from the work storing means. One of the plurality of works is held temporally by temporal work holding means 6 or 7 while the other work is conveyed to a jig Y. In the course of conveyance, a fixed sensor 63 detects the relative positional relationship between the work and the work gripping means 25. If the relative positional relationship deviates from the regular positional relationship, the movement of a robot arm 31 is corrected.Type: GrantFiled: December 28, 2006Date of Patent: August 18, 2009Assignee: Hirotec CorporationInventor: Makoto Tominaga

Patent number: 5525840Abstract: A semiconductor device has an alignment mark formed as a diffraction grating which comprises a plurality of unit markers arranged so that the period P of the diffraction grating is 8 .mu.m. The length d.sub.1 of each unit marker in the scanning direction of a laser beam is 4 .mu.m while the length L thereof in a direction perpendicular to the scanning direction is 4 .mu.m. Each unit marker comprises nine unit segments each of 0.8 .mu.m.times.0.8 .mu.m in size and arranged in an array of 3.times.3. Submicron openings constituting an unit segment has a small size for sufficiently filling the openings with deposited metal. An accurate alignment can be obtained by the alignment mark in an optical stepper for manufacturing semiconductor devices.Type: GrantFiled: November 9, 1994Date of Patent: June 11, 1996Assignee: NEC CorporationInventor: Makoto Tominaga
