Title: Elevator door opening/closing device
Inventor: OKUDA SEIJI
IPC: B66B13/28
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To prevent a foreign matter from being inserted in a gap between an elevator door and a doorway frame by picking up an image around the gap between the opening/closing door and the doorway frame, processing this image information, outputting a danger discrimination signal, and controlling the opening/closing action of the opening/closing door. SOLUTION: An image recognizing device 7 is fitted to the upper part inside of a doorway frame 2 and has a CCD camera, an image pickup element. An image processor processes image information on the basis of output of the image recognizing device 7 and outputs a dangerous state of a foreign matter such as the finger of a person 5 approaching the vicinity of a gap between the doorway frame 2 and a car door 1. A door control device controls the opening/closing action of the car door 1 on the basis of a danger discrimination signal of an image. That is, in case there is a danger of the foreign matter such as the finger of the person 5 being drawn in, a danger discrimination signal is outputted from the image processor, and the door control device receives this signal and holds the opening/closing action of the door 1.  The foreign matter such as the finger of the person 5 is thus prevented from being drawn into the gap between the opening/closing door 1 and the doorway frame 2.

Title: Wind resisting structure
Inventor: TOKUSHIGE MASAFUMI
IPC: E01D2/04
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To establish a higher flutter generating wind speed stably. SOLUTION: Two barrier members 20 in the form of vertical plate extending in the longitudinal direction of box girders 16 are installed in the center gap 18 between the two girders 16, and thereby the wind stream in the gap 18 is complicated, and such phenomena are produced complexly as promotion of draft to the gap 18, exfoliation of wind at the upstream barrier 20 and re- exfoliation of wind at the downstream barrier 20, and inclusion of vortices in the gap between the barriers 20. Thereby the dynamic air force acted to the downstream box girder 16 is allowed to act in the direction of suppressing the flutter, and the flutter generating wind speed is heightened.

Abstract: PURPOSE:To ensure that a specified slip friction load is added to a ribbon regardless of a change in the ribbon diameter of a ribbon feed shaft by providing a constitution in which, if a ribbon cartridge is attached, part of the ribbon is held between a holding member and a holding part, and this holding action is cancelled in the process of removal of cartridge. CONSTITUTION:If a ribbon cartridge B is attached to a carrier cover 12, the lower surface of the ribbon cartridge B comes in contact with the upper end of a stopper 8, and the stopper 8 is pressed downward. Subsequently, the stopper 8 rotates at a specified angle resisting the spring force of a coil spring 10. In turn, the upper end part of the stopper 8 leaves the short side end of an opening part 7b of a moving plate 7, that is, the upper end part is disengaged with the short side end. Further, the moving plate 7 moves due to the compression force of the coil spring 9, and part of a ribbon 14 of the ribbon cartridge B is held between the holding part 7a of the moving plate 7 and a holding member 6. Thus a specified slip friction load can be added to the ribbon 14.
