  • Patent number: 11821423
    Abstract: Provided is a scroll compressor that can prevent liquid from being accumulated, the scroll compressor including: a fixed scroll; an orbiting scroll; and a rotation shaft that extends in the horizontal direction and causes the orbiting scroll to orbit relative to the fixed scroll. Liquid is injected into a working chamber. An enclosing point of a working chamber formed near the outer end of a fixed wrap of the fixed scroll is positioned below a center of the rotation shaft and at the lowest point of the contour of the working chamber having shifted to the lowest position. The fixed scroll has an inclined wall surface that is positioned below the center of the rotation shaft, is made to face upward, and extends from the dust wrap to the outer end of the fixed wrap. The inclined wall surface is formed so as to be sloped down gradually from the dust wrap toward the outer end of the fixed wrap.

  • Patent number: 11465879
    Abstract: During a maintenance inspection, an optical rope diameter measuring device is provided at a predetermined position along a path of a wire rope, rope diameter is measured at multiple measuring points while the elevator is driven in test mode, and diameter reduction at each measuring point is determined and stored as a first diameter reduction (S2_S6). During a subsequent maintenance inspection, rope diameter is similarly measured at each measuring point to determine diameter reduction constituting a second diameter reduction (S7_S11). Based on these two diameter reductions, the time at which diameter reduction will reach a predetermined threshold value is predicted for each measuring point, and the earliest time is displayed as a rope replacement time (S12_S14).

  • Publication number: 20200071130
    Abstract: An elevator-rope inspection device comprising a camera for capturing images of the elevator rope R, and an image-processing unit for processing a captured image outputted by the camera, wherein the image-processing unit detects a location of wear by implementing binarization on the captured images, and a labeling process that assigns a label to the location of wear, measures a distance between labels 1, 2, and 3 assigned by the labeling process, and when that distance is less than a fixed value, it judges that the area between labels is a wire break, so texture information of the elevator rope is unnecessary in advance.

  • Publication number: 20090320554
    Abstract: [Object] To ensure a wear measurement over an entire section of a trolley wire and to facilitate the wear measurement, and also to perform the measurement during daytime, without being affected by structures existing around the trolley wire. [Means to solve] A line sensor 5 and an illumination lamp 6, which are placed in a direction of a scanning line perpendicular to a laying direction of a trolley wire, are mounted on a test car 1. The line sensor 5 shoots a pantograph contact surface of the trolley wire by the running of the test car, and this image signal is saved in a recording device 8 through a measurement computer 7. The measurement computer 7 arranges luminance signals of scanning lines, obtained by the line sensor 5, in time series, and creates a line sensor image. The measurement computer 7 gets a binary operated line sensor image from this line sensor image.
