Abstract: In a color picture tube apparatus, a deflection unit (27) is provided around a color picture tube (21) and a leakage magnetic (14) is generated from the deflection unit (27). A metal cover (32) made of aluminum, which covers an electrical power source is located in a space to which leakage magnetic field (14) is reached and a first opposition magnetic field is generated from the metal cover (32) due to the leakage magnetic field which produces an eddy current in the metal cover (32). A metal plate (34) made of a conduc­tive and non-magnetic material is so located between the deflection unit (27) and the metal cover (32) as to be substantially perpendicular to the metal cover (32). Thus, a second opposition magnetic field is so generated from the metal plate (34) due to the leakage magnetic field as to substantially cancel the first opposition magnetic field.

Abstract: In order to identify diamonds in gangue, incident laser radiation is scanned along an extended line across particulate gangue, and the diamonds 2 are identified by detecting the Raman radiation which is emitted, using a narrow pass band filter 9 in order to block out other radiation. In order to identify the position along the scan line from which the Raman radiation was emitted, the incident laser radiation is pulsed at a pulse frequency which changes along the scan line, and the frequency of the Raman radiation detected is sensed. In this way, one can simplify the equipment needed.

Abstract: Apparatus for the cross-correlation of two complex sampled digital data signals  X  and  Y  uses a first N-stage CORDIC rotator of pipeline sequential form for rotating each of the real and imaginary data portions of the first ( X ) complex sampled signal sequentially through a summation of angles ϑ=ξ i α i  (where ξ i =+1 or -1, α₁=90° and α n-2 =tan⁻¹(2 -n ) for n=0, 1, 2, 3,..., N-2) until X Im  is approximately zero and a substantially zero phase angle is reached. The sign from each i-th stage, of this first pipeline is also utilized to determine the sign of rotation in each like-positioned i-th stage of a plurality M of additional CORDIC pipeline rotators, where M is the total number of time delays at which the cross-correlation function is evaluated. The real and imaginary portions of the complete M-th interval cross-­correlation product are each obtained by multiplying the associated complex output of each of the  Y  pipeline rotators by the first pipeline magnitude signal output; N samples are then summed to provide at the j-th rotator output the appropriate pair of the real and imaginary parts of the j-th complex digital data output sample  C (j).
