Patent number: 7118219Abstract: An test tool for optometry includes a lens holding frame and a clip. The lens holding frame pivotally supports a trial lens to be mounted. The clip is attached to a rear side of the lens holding frame to clamp glasses. The lens holding frame has a pair of axi-symmetrical C-shaped rims having open ends and opposing closed ends, and a connecting portion that connects the opposing closed ends of the rims. Each rim has an inner surface that forms an accommodating space for holding the trial lens to be pivotal and movable in a left-to-right direction.Type: GrantFiled: March 14, 2003Date of Patent: October 10, 2006Assignee: Hoya CorporationInventor: Takashi Itagaki

Patent number: 6564451Abstract: On carrying out a hole filling method for a printed wiring board having an interlayer connection hole, first and second printed wiring boards (1 and 2) are prepared, each of which has the interlayer connection hole. The first printed wiring board is placed on a bottom plate (7). On the first printed wiring board, a first hole guide plate (8) having a first guide hole formed at a position corresponding to the interlayer connection hole of the first printed wiring board is placed in such a manner that the first guide hole is coincident with the interlayer connection hole of the first printed wiring board. A hole filling resin (9) is superposed on the first hole guide plate. On the hole filling resin, a second hole guide plate (10) having a second guide hole formed at a position corresponding to the interlayer connection hole of the second printed wiring board is placed.Type: GrantFiled: August 8, 2001Date of Patent: May 20, 2003Assignee: Japan Radio Co., Ltd.Inventors: Shigetoshi Abe, Tomoko Kato, Yasuo Sato, Takashi Itagaki, Kenji Matsumoto

Patent number: 5499809Abstract: A bank note conveying apparatus provides stable conveyance of bank notes by firmly pinching the bank notes from both sides. The apparatus comprises an endless belt 1 contacting one of the two faces of a bank note A, a belt driving mechanism which rotates the endless belt 1, a ball 2 which is provided to come into contact with the opposite face of the two faces of the bank note, and a holder 4 which supports the ball 2 to rotate freely. The holder 4 comprises a casing 4a which houses the ball 2 so that it is movable in the direction to and from the endless belt. A coil spring 7 is provided within the casing 4a which pushes the ball 2 in the direction of the endless belt.Type: GrantFiled: May 26, 1994Date of Patent: March 19, 1996Assignee: Kabushiki Kaisha Ace DenkenInventors: Takatoshi Takemoto, Toshikazu Chida, Noriaki Kano, Eiji Ito, Koji Murakami, Takashi Itagaki, Koji Sekimoto, Masanori Suzuki

Patent number: 5496020Abstract: A bank note transporting apparatus for transporting externally inserted bank notes is provided in an game machine island in which a plurality of game machines (12) and a plurality of game media lending machines (13) for lending game media used for playing games are disposed. The bank note transporting apparatus comprises a main transporting path (200) provided within the island for transporting bank notes to a destination position and an introducing path (300) disposed in at least one position along the length of the main transporting path for merging bank notes externally inserted into the island to the main transporting path. The main transporting path including an accepting slot (3) for accepting the bank notes from the introducing path. The introducing path including a bank note inserting unit (4) into which the bank notes are externally, inserted and a merging unit (9a) for guiding and transporting the inserted bank notes to the accepting slot.Type: GrantFiled: May 9, 1994Date of Patent: March 5, 1996Assignee: Kabushiki Kaisha Ace DenkenInventors: Takatoshi Takemoto, Toshikazu Chida, Noriaki Kano, Eiji Ito, Koji Murakami, Takashi Itagaki, Kozo Sekimoto, Masanori Suzuki
