A movement-distance measuring apparatus is provided with: an antenna, a phase detection circuit, a phase-shift calculation circuit, and a movement-distance calculation circuit. The antenna transmits a radio wave toward a plurality of reflectors arranged at constant intervals along a moving path of a moving object, and receives a reflected wave from the reflectors. The phase detection circuit detects a phase of the reflected wave received by the antenna. The phase-shift calculation circuit calculates a phase shift based on the phase detected by the phase detection circuit. The movement-distance calculation circuit calculates a movement distance of the moving object, based on the phase shift calculated by the phase-shift calculation circuit, and based on the interval of the reflectors.

Movement-distance measurement apparatus capable of reducing error due to change in angle of maximum reflection intensity according to movement and reducing error due to misalignment of antenna

A centrifugal compression test device includes a flow path forming section and an inlet space forming section. The flow path forming section forms an introduction flow path, an inlet flow path, and an interstage inflow path. The introduction flow path guides a fluid from the outside toward the inside in the radial direction. The inlet flow path is connected to the introduction flow path. The interstage inflow path extends from the outside toward the inside in the radial direction and is connected to the inlet flow path. The inlet space forming section is formed an annular shape having an introduction opening section through which a fluid is introduced from a part in the circumferential direction and the outside in the radial direction at the first side of the introduction flow path. Further, a front end of the introduction flow path is connected to the inlet space forming section.

In an elevator car position detection device, a magnetic field generator generates an eddy current magnetic field on an identification member, and a magnetic field detector detects the eddy current magnetic field generated on the identification member. The identification member includes a plurality of conductors which are continuously arranged along an ascending and descending direction of a car, and are relatively different in a plate thickness with respect to a skin depth of an eddy current generated by the magnetic field generator on the identification member. A shape of at least a part of a boundary between the adjacent conductors is a straight line or a curve tilted with respect to a direction orthogonal to the ascending and descending direction of the car.

A control cable guide device for an elevator, which is to be mounted to a control cable suspended between a middle portion of a hoistway and a lower portion of a car, the control cable having a curved portion formed at a lower end position of the control cable, the control cable guide device including an arm to be suspended on the control cable at a position below the car in a pivotable manner. The arm is configured to be pushed upward by the curved portion when the car is caused to travel to a lowermost position within a normal traveling range, to thereby shift to a cable receiving position for receiving the control cable while being partially projected from the car in a horizontal direction.

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.

Elevator position detection apparatus

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.
