Transfer apparatus using electrostatic attraction and transfer method using electrostatic attraction
Patent number: 10957934Abstract: A transfer apparatus using an electrostatic attraction includes an electrostatic chuck for attracting and placing a workpiece as a transfer member on a placement surface by electrostatic attraction. The electrostatic chuck is grounded by an earth via a ground electrode after the electrostatic chuck receives electric power from a power supply surface of a power source via power receiving electrodes of the electrostatic chuck, so that the electrostatic chuck is configured to attract and place the workpiece on the placement surface by electrostatic attraction in a state where electrostatic balance is broken.Type: GrantFiled: January 25, 2019Date of Patent: March 23, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Hirohiko Hisano -
Publication number: 20200112042Abstract: An assembly apparatus for a membrane-electrode-gas diffusion layer-assembly for a cell for fuel cell capable of positioning and assembling materials while suppressing failures is provided. An assembly apparatus includes a pair of transfer rollers, a first detection unit, a second detection unit, and a conveyance unit. The conveyance unit includes a pair of first rollers and a pair of second rollers. The pair of first rollers are arranged to be separated in a width direction of a band-shaped sheet intersecting with a conveying direction, and rotate in contact with the preliminary assembly. The pair of second rollers are arranged to be separated in the width direction, and rotate while sandwiching the preliminary assembly with the pair of first rollers. An inclination at least one of the first roller or the second roller varies with respect to the conveying direction together with the preliminary assembly.Type: ApplicationFiled: September 19, 2019Publication date: April 9, 2020Inventor: Hirohiko HISANO

Patent number: 10392703Abstract: A plasma CVD apparatus is provided. The plasma CVD apparatus includes: a chamber forming a plasma space; and a power introduction terminal arranged in a terminal insertion hole that extends through a wall of the chamber. The power introduction terminal includes an insulator having a through hole and a rod-like electrical conductor inserted in the through hole. One end of the conductor is arranged in the chamber and the other end of the conductor is electrically connected to a power source that supplies power into the chamber. A gap between an inner wall of the insulator and the rod-like electrical conductor is less than 2 mm. A distance from one end of the insulator, which is arranged in the plasma space inside the chamber, to a contact point between the insulator and the conductor is greater than 10 mm.Type: GrantFiled: March 16, 2015Date of Patent: August 27, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hirohiko Hisano, Masafumi Koizumi

Publication number: 20100288740Abstract: A laser processing apparatus comprises a first shift mechanism including a first transparent member having a first incident face and a first output face that are parallel to each other; and a first motor that rotates the first transparent member around a first rotational axis. The first shift mechanism shifts the laser beam exiting from the first output face in a state parallel with the incident light on the first incident face in a first direction. The laser processing apparatus also comprises a second shift mechanism including a second transparent member including a second incident face and a second output face that are parallel to each other; and a second motor that rotates the second transparent member around the second rotational axis. The second rotating mechanism rotates the laser beam exiting from the second output face in a state parallel with the laser beam incident on the second incident face in a second direction perpendicular to the first direction.Type: ApplicationFiled: February 19, 2009Publication date: November 18, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomoki Komiya, Hirohiko Hisano, Akio Sato, Tomoya Okuno
