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

Patent number: 7034392Abstract: A filter chip lying on an upper surface of a top layer package substrate is connected to an upper surface ground electrode (235). The upper ground electrode (235) and a lower surface ground electrode (237) are connected to each other via through electrodes (261, 262, 263), ground wiring patterns (251, 252), first connecting lines (271 to 276), and second connecting lines (281, 282). The first connecting lines (271 to 276) are connected to the ground wiring patterns (251, 252), whereas the second connecting lines (281, 282) are not connected to the ground wiring patterns (251, 252), respectively. Owing to the provision of the connecting lines connected to the ground wiring patterns (251, 252) and the connecting lines unconnected to the ground wiring patterns (251, 252), the impedance between a multilayer package substrate and ground can be adjusted.Type: GrantFiled: July 8, 2004Date of Patent: April 25, 2006Assignee: Oki Electric Industry Co., Ltd.Inventors: Akio Hirakawa, Yoshiaki Fujita, Tomokazu Komazaki

Patent number: 7017714Abstract: There is provided a double-deck elevator which does not cause any impacts or vibrations on each cage when adjusting the spacing in the vertical direction between upper and lower cages. Loads on an upper support beam from right and left support arms for hoisting and supporting the upper cage are measured by right and left upper measuring units. Similarly, loads on a lower support beam from right and left support arms for hoisting and supporting the lower cage are measured by right and left lower measuring units. Because the magnitude of the loads on the right and left screw shafts can be obtained correctly, any impacts or vibrations caused on each cage can be prevented when adjusting the spacing in the vertical direction by correctly controlling the drive torque output from right and left drive motors.Type: GrantFiled: March 18, 2003Date of Patent: March 28, 2006Assignee: Toshiba Elevator Kabushiki KaishaInventors: Yoshiaki Fujita, Naoki Kondo
