Abstract: In a satellite communications system, a rotatable 90 o  phase shifter (4) and a rotatable 180 o  phase shifter (3) introduce variable phase shifts to a single pilot signal, which is transmitted to the satellite. Downlink cross-polarization interference cancelling control signals are derived from a beacon signal received from the satellite. A pulse sequence is generated to modulate the amplitude of a carrier to produce an ASK signal as the pilot signal. A correlation calculator (19) provides coarse mode interference cancellation by estimating uplink cross-polarization interference components from the downlink cross-polarization cancelling control signals and adjusting the angle settings of the 90 o  and 180 o  phase shifters with the estimated components. The pilot signal is transmitted back to the earth and synchronously detected with the pulse sequence to derive a DC signal which represents an uplink cross-polarization interference. A stepwise tracking controller (16) provides fine mode interference cancellation by stepwisely varying the 90 o  and 180 o  phase shifters by predetermined amounts an detecting previous and recent values of the synchronously detected DC signal resulting from the stepwise variations, and repeating the stepwise variations until a difference between the previous and recent values is substantialy reduced to a minimum.

Abstract: Phase enhancement means are employed in conjunction with linear feedback shift registers to generate sequences of binary pattern vectors which are much more structurally independent of one another thus enabling more thorough and comprehensive testing of integrated circuit systems. More particularly, the present invention employs a plurality of exclusive-OR gates in an array of one gate per shift register output cell to generate the desired uncorrelated pattern strings. This facilitates testing of integrated circuit devices and systems and is particularly useful for built-in test situations for very large scale integrated circuits which employ pseudorandom test methods.

Abstract: 2.1 The axle load of the mechanically sprung drive axle of running gear comprising a lift axle can be described by the spring deflection of the suspension spring and the pressure of the lift bellows. A known device has a signal body which can be displaced axially by the pressure and rotated by the spring deflection. A three-dimensional characteristic diagram is arranged on the signal body and determines for each constellation of rotation position and axial position a distance which forms the axial load signal to be obtained. Because of the signal body with the three-dimensional characteristic diagram the known device constitutes a complex solution, particularly when the lift axle running gear is only operated with rigid axle load participation of the lift axle, i.e. with only fully raised or fully lowered lift axle. 2.2 In order to simplify the known device, particularly for the last-mentioned mode the invention proposes to displace the signal body (22) axially, independently of the spring deflusion, and to replace the three-dimensional characteristic diagram by a two-dimensional contour (21, 33). 2.3 Preferred application area is vehicle technology. <IMAGE>

Abstract: In an optical unit (2) incorporated in a laser beam printer, a laser beam generated by a laser diode is converted by a group of conversion lenses (14, 16, 18) into a laser beam having a predetermined-size cross section. The laser beam is directed toward a photosensitive body (90) by a scanner unit (50), so as to scan the photosensitive body. A focusing lens (72) allows the rotating angle of the reflecting faces (68) of the scanner unit to correspond to a desirable point on the surface of the photosensitive body. In other words, the rotating angle is made to correspond to the distance between the optical axis center determined with respect to a main scanning direction and a point to which the laser beam is irradiated for scanning. Each of the reflecting faces (68) of the scanner unit is convex. The focusing lens (72) is constituted by an aspheric-surface plastic lens having a toric surface which is rotation-symmetric with reference to an axis extending in the main scanning direction. The rotating angle of the convex mirrors (68) of the scanner unit (50) is determined in accordance with the characteristics of the focusing lens (72). Therefore, both the field curve and the fϑ characteristic can be corrected.
