  • Publication number: 20190086369
    Abstract: In a rope damage diagnostic testing apparatus, an ultrasound applicator generates ultrasonic waves in a wire rope by making the wire rope vibrate due to magnetostriction effect. A detecting element detects changes in a state of propagation of the ultrasonic waves in the wire rope. An excitation coil and the detecting element are disposed in a parallelogram that has as a first opposite side length a length of a portion of the wire rope in which one of the outer layer strands makes one revolution around the wire rope, and that has as a second opposite side length a product of a diameter and number of the outer layer wires that are included in one of the outer layer strands.

  • Patent number: 10144613
    Abstract: A detection subject body provided in a hoistway includes an ID sequence formed by arranging three or more types of segments having different magnetic properties in a movement direction of an elevating body. An eddy current type detection unit is provided on the elevating body to generate signals corresponding to the magnetic properties of the respective segments. An identification unit identifies the respective types of the segments on the basis of the signals from the detection unit, and outputs a time series signal in a different output condition depending on the type of each segment. A digital data conversion unit converts the time series signal into digital data on the basis of variations in the output condition of the time series signal from the identification unit. A position specification unit specifies the position of the elevating body on the basis of the digital data.

  • Patent number: 10065833
    Abstract: In an elevator position detection apparatus, when a first diagnosis switch is closed, a diagnosis coil generates a first induced magnetic field, and when a second diagnosis switch is closed, the diagnosis coil generates a second induced magnetic field that is weaker than the first induced magnetic field. In a constant L output fault diagnosis mode in which the first induced magnetic field is generated, an output value of a measurement signal falls below a threshold regardless of whether or not a detection subject body is present in a detection region. In a constant H output fault diagnosis mode in which generation of both the first and the second induced magnetic fields is stopped, the output value of the measurement signal equals or exceeds the threshold regardless of whether or not the detection subject body is present in the detection region.

    Abstract: A detection subject body includes a first detection subject plate provided with an ID sequence and a second detection subject plate provided with a clock sequence. A detector includes a first detection unit that outputs, as an ID signal, a time series signal that switches condition in a boundary position between a first property portion and a second property portion of the ID sequence when the ID sequence passes through a first detection region, and a second detection unit that outputs, as a clock signal, a time series signal that switches condition in a boundary position between a first property portion and a second property portion of the clock sequence when the clock sequence passes through a second detection region. A processing unit specifies a position of the elevating body by reading the condition of the ID signal in a position where the condition of the clock signal switches.

    Abstract: An optical receiver is provided with a photoelectric converter that outputs an electrical signal according to light that is received by a light-receiving region. The optical receiver is provided with a condensing lens and optical filter that are located in an optical path from where signal light enters towards the light-receiving region. The condensing lens condenses the signal light onto the light-receiving region. The optical filter reflects light having a first wavelength that is included in the signal light using a front surface thereof and reflects light having a second wavelength that is included in the signal light using a rear surface thereof that faces the front surface so that the light is emitted through the front surface.

  • Patent number: 8953164
    Abstract: The transmittance of a filter periodically varies with respect to the incident light frequency. Provided that fk is the sum of Fk and ?k, or the difference obtained by subtracting Fk from ?k, depending on the kth light source among multiple light sources, an incidence guide causes light from the plurality of light sources to be incident on the filter such that the propagation angle of light when light from the kth light source propagates through the interior of the filter equals ?k obtained by computation using fk. The incidence guide causes light to be incident on the filter, taking fk to be the sum of ?k and Fk for at least one of the light sources, and taking fk to be the difference between ?k and Fk for at least one other of the light sources. A detector detects the intensity of transmitted light that transmits through the filter.
