    • PURPOSE: An optical encoder outputs output signals without fixed slits as waveforms of the output signals are determined according to a shape of the whole light receiving region. CONSTITUTION: An optical encoder includes a rotator, a light source, and a light receiving unit. Rotation slits of identical pitches are formed on the rotator. The light source emits lights penetrating through the rotation slits. The lights penetrated through the rotation slits are incident to the light receiving unit. The light receiving unit includes a light receiving region (340) generating output signals according the incident lights; and an electrode (380) which is connected to the light receiving region and outputs output signals to the outside. A waveform of the output signals is determined depending on a shape of the light receiving region.

    • PURPOSE: A device and a method for measuring the handling position of a nozzle are provided to calculate a difference between the current position and a target point of a shroud nozzle when the shroud nozzle is coupled to the bottom end of a ladle. CONSTITUTION: A device for measuring the handling position of a nozzle comprises a nozzle manipulator(110), rotation angle sensors(130), and a controller(150). The nozzle manipulator horizontally and vertically moves a shroud nozzle(15) through one or more rotary shafts and fixes the shroud nozzle to the bottom end of a ladle(10). The rotation angle sensors are installed in the rotary shafts of the nozzle manipulator and detect the rotation angle of each rotary shaft. The controller calculates the current position coordinate of the shroud nozzle installed in one side of a support frame(111) depending on the detected rotation angle signals and calculates a difference between the current position coordinate and a pre-set target point.

    • A main scale of an optical displacement measuring apparatus has slits arranged on it at regular intervals, a part of which is a missing slit that does not allow light to pass through used for detecting the original point. An index scale has four sets of windows formed on it. The four windows are arranged with mutual phase differences of ¼ P, where P is the pitch of the arrangement of the slits. When a part of the missing slit overlaps with the index scale, no light reaches to photodiodes from the missing slit and only a partial light flux passes through a window, so that the light quantity decreases. An original point signal associated with the missing slit can be obtained by adding up the outputs of all the photodiodes.
