| 20120091928 | POSITION DETECTOR FOR MOVING MAGNET TYPE LINEAR MOTOR - The present invention provides a position detector which can detect the position of a mover on the side of a stator, and which realizes detection with high accuracy in a moving magnet type linear motor. | 04-19-2012 |
| 20110284329 | ELEVATOR GROUP CONTROL METHOD AND DEVICE THEREOF - Provided are a group control method and a group control device capable of efficiently controlling the operation of elevators in diversified traffic situations and under a variety of specification conditions required for a group management system. A plurality of elevators are placed in service for a plurality of floors, an evaluation index for a newly made hall call is calculated, and the best suited car is selected and assigned to the hall call based on the evaluation index in the group control method of elevators. A waiting time expectation value of all passengers on all floors for each direction, either that have already occurred or that are expected to occur within a predetermined time period, is taken as the evaluation index, the waiting time expectation value being the expectation value for the sum or the average of waiting time. | 11-24-2011 |
| 20110221282 | MOVING MAGNET TYPE LINEAR MOTOR - The moving magnet type linear motor according to the present invention comprises a stator comprising a plurality of coils arranged in a single direction and having a both ends support structure supporting both ends of the stator in a direction perpendicular to said single direction, a pair of movers comprising a plurality of permanent magnets arranged opposing the sides of the stator respectively and capable of relative movement in said single direction with respect to each other, and guidance mechanisms guiding both the movers independently and movably in said single direction, and one of the movers is connected to a load. | 09-15-2011 |
| 20110192684 | ELEVATOR SAFETY DEVICE - There is provided an elevator safety device that can prevent a light beam from being looked into. The elevator safety device according to the present invention includes light emitting means for emitting a light beam crossing an entrance; light receiving means for detecting the light beam emitted from the light emitting means; foreign matter detection means for generating a foreign matter detection signal when detection of the light beam by the light receiving means is interrupted; and control means. The control means causes the light emitting means to stop an emission in a fully opened state of car doors, and causes the light emitting means to start the emission at a start of or during a closing operation of the car doors. | 08-11-2011 |
| 20110155511 | SAFETY DEVICE FOR ELEVATOR - In a safety device for an elevator, on one car door among a pair of car doors, a light-emitting/light-receiving unit is disposed facing downward at an upper end position of a vertical line separated by a predetermined distance from an end face in a closing direction, which is to abut the other car door, toward the side of the other car door, and a first reflecting member is disposed facing upward at a lower end position of the vertical line. A housing space that houses the light-emitting/light-receiving unit in a state where both car doors are closed is formed on the other car door, and a second reflecting member is disposed facing upward at a bottom portion of the housing space and extends from the same position as an end face in a closing direction of the other car door toward the back of the housing space. | 06-30-2011 |
| 20090266675 | STEP MECHANISM OF TRANSPORT DEVICE - A transport device includes a plurality of endlessly connected steps ( | 10-29-2009 |
| 20090058333 | ELEVATING MACHINE CONTROL APPARATUS - An elevating machine control apparatus controls an inverter ( | 03-05-2009 |
