Abstract: The invention relates to a method and arrangement for target seeking, where a rotatable instrument emits an electromagnetic radiation and automatically searches for a target reflector by detecting whether reception occurs of electromagnetic radiation received by the target reflector and reflected back to the instrument. In the beam path of the electromagnetic radiation, polarization of the electromagnetic radiation, polarization modulation of the polarization direction on the electromagnetic radiation by alternately changing it, and polarization of the electromagnetic radiation take place in sequence. At least on of these steps is performed at the target reflector. Checking of the detected reflector is carried out by testing if the received radiation changes at the same rate as the modulation of the polarization direction. Only targets are accepted which give different signal strengths at said rate for the received radiation.

Abstract: An information reproducing apparatus for recovering data stored on a recording disc. Table of contents (TOC) data is read from a recorded disc to define the tracks of program material on the recording disc in terms of absolute times which represent each track. A selected track may have a desired order number which is divided into sub tracks, represented by sub absolute times. When a portion of a track is to be read, a search for the sub track permits reproduction of the data on the track from a portion defined by the sub track.

Abstract: A sealing device comprising a supporting assembly (9) containing sealing members (16) supporting the instrument column (5), and an assembly (17, 18) for lifting the instrument column (5) in sealing engagement with the supporting members (16). The sealing members (16) supporting the instrument column (5) include a clamping ring (28) and at least one O-ring seal (29, 30).

A spreading bush encompasses the threaded stem.

Abstract: Representative vectors z.sub.1i and z.sub.2j are selected from codebooks CB1 and CB1, respetively, and multiplied by weighting coefficient vectors w.sub.1 and w.sub.2 of the same number of dimensions as those of the representative vectors, whereby weighted representative vectors z.sub.1i w.sub.1 and z.sub.2j w.sub.2 are generated. These weighted representative vectors are vector combined into a combined vector y.sub.ij, and a combination of the representative vectors is selected by a control part in such a manner as to minimize the distance between the combined vector y.sub.ij and an input vector X. The weighting coefficient vectors w.sub.1 and w.sub.2 each have a maximum component in a different dimension and are selected so that the sum of diagonal matrixes W.sub.1 and W.sub.2 using components of the weighting coefficient vectors as their diagonal elements becomes a constant multiple of the unit matrix.

Abstract: An apparatus in a paper or board machine for dewatering a web carried along a first wire section and prior to introduction of the web to a press section of the paper or board machine. The apparatus comprises a first pair of water removing rolls for receiving the web and the first wire section which include a non-suction water receiving roll which is mounted on a first side of the web and has an open surface for receiving and temporarily holding water removed from the web, and a non-suction smooth surfaced roll mounted on the second side of the web. A second permeable wire section is brought in contact with a side of the web opposite that of the first wire section while passing through the pair of rolls. The first and second wire sections produce a press nip when they pass through the pair of water removing rolls with the web to remove water from the web, the water being removed to openings in the open surface of the non-suction water receiving roll.

The first movable element causes the second movable element to cooperate with and at least partly expel the terminal from the cavity in the event the elastic lance fails to correctly engage the terminal.

Abstract: An IDFT section has a set of input terminals subjected to components of an information signal respectively. The IDFT section subjects the information signal to inverse discrete Fourier transform to convert the information signal into a pair of a first in-phase signal and a first quadrature signal while assignment of the components of the information signal to the input terminals is in a first state. A first power-related value of one of the first in-phase signal and the first quadrature signal is calculated. The first in-phase signal and the first quadrature signal are written into an output buffer memory when the calculated first power-related value does not exceed a predetermined reference value. The assignment of the components of the information signal to the input terminals is changed from the first state to a second state when the calculated first power-related value exceeds the predetermined reference value.
