Patent number: 7019227Abstract: In a case where a left-hand push-button switch is ON, a second relay RL2 is electrically de-energized to open a normally close contact RL2-1 of the second relay RL2 so that a relay contact circuit RC is opened. If, in this state, a right-hand push-button switch is shifted to a second OFF state, a normally close contact R3-1 of the right-hand push-button switch is opened. Thus, a third relay RL3 is not electrically de-energized and a first and a second circuits are in cutoff until both the right-hand and the left-hand push-button switches are returned to a first OFF state.Type: GrantFiled: August 22, 2001Date of Patent: March 28, 2006Assignee: Idec Izumi CorporationInventors: Takao Fukui, Kenji Miyauchi, Kazuya Okada, Yasushi Kamino, Ken Maeda, Yoshio Sekino, Masaki Nobuhiro

Patent number: 6911609Abstract: A push-button switch 5 disposed in a switch case 3 has c-contacts and a normally close contact electrically connected with a terminal block 9 via conductors 39. Leading ends 23 of cores of a cable 7 introduced into the switch case 3 are inserted in insertion holes 49a, 49b formed in the terminal block 9. Screws 53a, 53b mounted to the terminal block 9 are tightened to press the leading ends 23 of the cores against conductive connection portions, on one side, in the insertion holes 49a, 49b, thereby to establish electrical connection.Type: GrantFiled: September 12, 2001Date of Patent: June 28, 2005Assignee: Idec Izumi CorporationInventors: Kenji Miyauchi, Takao Fukui, Kazuya Okada, Yasushi Kamino, Ken Maeda, Yoshio Sekino

Patent number: 6660949Abstract: An actuator of the present invention comprises an operation key 2 to be inserted into a key insertion hole formed in the safety switch, and a base 3. The operation key 2 is held on the base 3 and capable of freely swinging in two orthogonal directions. The actuator also comprises means (e.g. a guide stopper 4 and engagement spaces 34) for selectively restricting the swinging movement of the operation key 2 to either of the two directions.Type: GrantFiled: August 24, 2001Date of Patent: December 9, 2003Assignee: Idec Izumi CorporationInventors: Yasushi Kamino, Takao Fukui, Yoshio Sekino, Kenji Miyauchi, Hideo Niinai, Tokunori Tanaka, Kazuya Okada, Ken Maeda, Yoshihiro Shima

Patent number: 6627830Abstract: A push-button switch and a teaching pendant employing the same are provided. The push-button switch ensures that a push button is capable of switching ON/OFF the switch if one of contacts thereof should fail during an operation of the switch. For achieving this object, a switch case 3 contains two c-contacts 9a, 9b each having a snap action configuration and switching mechanisms 11a, 11b for opening/closing the c-contacts 9a, 9b. When a push button 5 is depressed, the switching mechanisms 11a, 11b simultaneously open/close the c-contacts 9a, 9b for turning ON/OFF a push-button switch 1.Type: GrantFiled: March 28, 2002Date of Patent: September 30, 2003Assignee: Idec Izumi CorporationInventors: Takao Fukui, Kenji Miyauchi, Kazuya Okada, Yasushi Kamino, Ken Maeda, Yoshio Sekino

Patent number: 6388640Abstract: A user changes the shapes of the side frames from the shapes at the positions indicated by dashed lines at which no external force is applied to those at the positions indicated by dashed lines, and mounts the side frames on the head. As a result, the side frames and rear mount pads perfectly fit on the head, as indicated by solid lines. The user therefore can see video on a main body of a display unit in a natural state without any strain.Type: GrantFiled: December 30, 1998Date of Patent: May 14, 2002Assignee: Canon Kabushiki KaishaInventors: Tatsuo Chigira, Kenji Miyauchi, Hironori Takano

Patent number: 6175406Abstract: An image reading apparatus includes a carriage for holding a film holder holding a film, a motor for moving the carriage, and a housing for holding the carriage and the motor. While the motor moves the carriage, a first portion of the carriage is positioned by being slidably clamped by the housing, and a second portion which is in the opposite side of the first portion of the carriage is slidably positioned by a guide shaft. An image reading apparatus includes an image sensor for sensing an image from an original, a conveyor for conveying the original, a first board on which an image processing circuit for performing predetermined processing for an image signal output from the image sensor is mounted, and a second board on which a power supply circuit for supplying power to the image processing circuit is mounted.Type: GrantFiled: November 5, 1997Date of Patent: January 16, 2001Assignee: Canon Kabushiki KaishaInventors: Toshimi Iizuka, Masahito Natsume, Kenji Miyauchi, Yoshinari Onda, Toshiki Ishino
