Abstract: A vehicle radio (10) having a microprocessor based control (10) has bass and treble tone controls (22,24) and a fade control (26) to produce digital settings. A tone adjusting arrangement compensates for the effect of fade change on perceived tone or frequency response.

Abstract: Compensation for process direction motion of a photoreceptor (24) in a Raster Output Scan system is provided by moving the cylinder lens (16) located between the laser source (12) and a rotating spot scanning mechanism, e.g., a polygon (20). The cylinder lens is moved in the process direction in response to error signals generated by a start of scan (SOS) detector (30) and timing marks (34) on the photoreceptor drum surface, or an encoder on the drum shaft. The lens movement is obtained by sending motion error signals to a piezo-electric actuator (18) which increases in length to impart the desired motion to the cylinder lens.

Abstract: A pipe diffuser (11) is used in a centrifugal compressor in such a way as to obtain high efficiency over a broad operating range. The number of channels in the pipe diffuser (11) is limited such that the wedge angle is relatively large and therefore not susceptible to flow separation at the leading edges thereof. The vaneless space between the impeller (12) and the leading edge circle of the diffuser (11) is limited in its radial depth such that the flow separations are further inhibited. Finally, the impeller (12) has a relatively high backsweep such that the absolute flow exit angle is relatively low, thereby reducing the sensitivity to lower flow conditions.
