摘要： An apparatus is provided for tensioning a drive belt, which apparatus consists of tensioner arm having an idler pulley thereon for engagement with the surface of a drive belt, structure for mounting the tensioner arm to a support for pivoting movement in first and second opposite directions relative to the support, and a torsion coil spring formed of wire and acting between the mounting structure and tensioner arm for biasing the tensioner arm in one of the first and second directions. The wire has a non-circular cross section.

摘要： A frequency interpolating device for restoring a signal similar to the original signal by creating a suppressed frequency component of a specific frequency band of the original signal, approximately from the input signal having the suppressed frequency component. In the frequency interpolating device, when the suppressed frequency component is artificially created from the input signal and added to the input signal, the additional level is set dynamically and adaptively on the basis of the spectrum pattern of the remaining frequency component of the input signal. This setting of the addition level is done by searching a look-up table which stores data that causes a plurality of reference frequency spectrum patterns to be associated with predetermined addition levels. Moreover, the data stored in the table is created on the basis of the results of either an aural test on a plurality of signal sample sounds or a physical frequency analysis on the massive signal data.

摘要： An apparatus for tensioning a belt consisting of a tensioner arm having an idler pulley for engagement with a surface of a drive belt, structure for mounting the tensioner arm to a suppport for pivoting movement about a pivot axis in first and second opposite directions, and structure for biasing the tensioner arm in one of the first and second directions. The mounting structure includes first and second members with first and second relatively movable cooperating friction generating surface for damping rotation of the tensioner arm. At least a portion of one of the friction generating surfaces is concave opening towards the tensioner with at least one of the friction generating surfaces having at least a portion defined by other than a radius centered on the pivot axis of the tensioner arm to thereby produce a greater resistance to rotation of the tensioner arm in the other of the first and second directions than in the one of the first and second tensioner arm pivoting directions.
