Patent number: 7600627Abstract: A conveyor apparatus is provided that is free of a pulsing motion in the circulating chains so as to provide a comfortable ride quality on its steps. The conveyor apparatus includes a step guide rail, a plurality of steps, a step chain, and a chain driving mechanism for driving the step chain. The chain driving mechanism includes a rotating and driving unit, a driving sprocket which is rotated by a driving force given by the rotating and driving unit, and a circulating chain for giving a thrust to the step chain. The circulating chain has chain links and hinges that are to be connected to the adjacent chain links. The chain link includes a placing surface on which the step roller is placed, and pressing surfaces that are in contact with step rollers.Type: GrantFiled: August 24, 2007Date of Patent: October 13, 2009Assignee: Toshiba Elevator Kabushiki KaishaInventors: Yoshinobu Ishikawa, Kenzo Tonoki, Taihei Koyama, Yoshio Ogimura, Takayuki Kikuchi, Nobuhiro Oku, Shin Murakami, Hitoshi Kawamoto

Publication number: 20070164618Abstract: The main body of a rotary electrical machine is accommodated in a frame (1). A circulatory device (5) is provided that is rotated by a rotor (3) of said rotary electrical machine, in which there is accommodated cooling liquid (7) that cools at least the main body of the rotary electrical machine. The circulatory device (5) circulates said cooling liquid (7) to outside of the frame (1) by pump action. The cooling liquid (7) is accumulated by a reserve tank before being circulated within the frame (1). After the heated cooling liquid (7) is cooled in the reserve tank, this accumulated cooling liquid (7) is then caused to flow back into the frame (1) by the pressure difference.Type: ApplicationFiled: December 22, 2006Publication date: July 19, 2007Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Taihei Koyama, Shinichi Noda, Kenzo Tonoki, Shigetomo Shiraishi

Patent number: 7243760Abstract: An elevator door unit includes cage doors, a cage door lock unit, hall doors, and a lock release unit. The cage doors are provided in a cage which moves in a shaft. The cage door lock unit limits and locks the opening width of the cage doors to the width not to permit passing of passengers. The hall doors are provided in a landing hall, and opened interlocking with the cage doors, when the cage stops in a range of facing to the cage doors. The lock release unit releases the cage door lock unit within the opening width by opening the cage doors by manual operation, when the cage stops in a range that the cage doors face to the hall doors.Type: GrantFiled: February 11, 2004Date of Patent: July 17, 2007Assignee: Toshiba Elevator Kabushiki KaishaInventors: Kenzo Tonoki, Yoshiaki Fujita, Shin Murakami, Norihito Togashi

Patent number: 7178638Abstract: A car door apparatus of an elevator includes a pair of door panels, a door drive device, and a door-opening mechanism. The pair of door panels open and close a doorway of the car of the elevator. The door drive device drives the door panels to open and close the doorway using electric power. When the car is stopped in an emergency in which a power source for driving the elevator is shut off, the door-opening mechanism starts up the door drive device using a secondary battery to move the door panels in the opening direction by a predetermined distance respectively to make a predetermined clearance between the door panels.Type: GrantFiled: September 7, 2005Date of Patent: February 20, 2007Assignee: Toshiba Elevator Kabushiki KaishaInventors: Yoshiaki Fujita, Kenzo Tonoki, Norihito Togashi
