Abstract: The present invention provides a filter assembly for use in filtering and treating contaminated water 14 in an aquarium tank 40. A filter bag 10 is used for receiving a continuous supply of contaminated water 14 under a predetermined pressure. The walls 12 of the filter bag 10 are made at least partially of a porous filter membrane formed of a matrix of pressure displaceable fibrous material. As the filter 10 clogs with contaminants, bacterial growth and accompanying by-products, the fibrous material is displaced to increase the size of the interstices of the matrix to permit water 14 to continue to flow through the interstices and continue filtering.

Abstract: A plurality of blades extend radially from a a hub which is rotated by a motor about a drive axis. Each blade has a root which is rotatably connected to the hub so that it can be independently twisted to vary the pitch thereof relative to the drive axis. A plurality of electromagnets are annularly positioned adjacent the hub so that permanent magnets connected to the roots of corresponding blades can be attracted and/or repelled to induce twisting motion in the blades as the hub rotates about its drive axis. A control circuit receives input commands for a manual control device and causes predetermined electrical signals to be applied to the electromagnets for simultaneously varying the pitch of the blades. The pitch of the blades can be varied cyclically and collectively in accordance with any real continuous function, and not just sinusoidally as in the case of prior mechanical linkages employing swash plates. A vessel equipped with the propeller system at the fore and aft ends thereof can be precisely maneuvered in six degrees of freedom.

Abstract: An image signal processing apparatus comprises a memory (12) and an address generator (14) that generates addresses for allocation to successive words of a digital input signal (10) representing an input image for mapping those words (or words obtained by interpolation therefrom) into the memory (12) in such a manner that individual portions of the mapped image stored in the memory may be compressed and/or rotated with respect to corresponding portions of the input image. A digital filter (40) of variable bandwidth effects two-dimensional filtering of the image before it is stored in the memory (12). Local scaling factor computation means (42) monitors the addresses allocated by the address generator (14) to successive sets of words of the input signal corresponding to successive local image areas and computes from each set of addresses, for the corresponding set of words, a local scaling factor representing the extent of compression and/or rotation of the local area. Bandwidth control means (44) is responsive to the successive local scaling factors computed by the computation means (44) to vary the bandwidth of the filter (40) in a sense to minimise aliasing that would be caused by compression and/or rotation of the local areas.

Abstract: For temporally detecting and imaging a point of a specimen, which carries a signal of at least one particular frequency, a secondary signal is generated in a microscope. A primary beam (PE) is modulated with at least one particular frequency (fb), this frequency (fb) being different from at least one frequency (fs) of the signal which is carried by the point. The resultant signal is thus mixed to form a particular intermediate frequency (df) and finally demodulated into two features, which are in the frequency domain, of the secondary signal in a measurement processing arrangement (MV, MV'). The temporal signal of the specimen is subsequently recovered by means of an inverse Fourier transformation in the computer (R). <IMAGE>

Abstract: The invention relates to a magnetic recording and reproducing apparatus for eliminating the crosstalk component from an adjacent track and obtaining a high picture quality. Chrominance signals in the base band which are produced by a low frequency conversion chroma signal are supplied to comb-shaped filters which are used in the magnetic recording and reproducing apparatus. The chrominance signals in the base band are obtained by generating (25 to 36) carriers (ø₁, ø₂) synchronized with a burst signal of the low frequency conversion chroma signal including the jitter component upon reproduction and by multiplying (5, 6) the carriers (ø₁, ø₂) and the low frequency conversion chroma signal. A burst signal portion between the resultant chrominance signals in the base band is applied as a frequency control input signal to an oscillator as the carrier generating source (25 to 36), so that desired carriers (ø₁, ø₂) are derived. Thus, the frequency fluctuation is eliminated from the converted chrominance signal in the base band and the high picture quality can be realized.

Abstract: Data of "0" and "1" are input to input pad (10) which is provided for each dRAM chip. The data is input to two data input buffers (14a, 14b) via protection cir­cuit 12. Each of data input buffers (14a, 14b) senses the level of input data, converts the sensed level to the MOS level and outputs the MOS level data. Data input buffers (14a, 14b) are respectively supplied with control signals (φa, φb) for determining the sense-­timings thereof. The phases of control signals (φa, φb) are shifted from each other. Selection circuit (16) selects an output of one of data input buffers (14a, 14b) in synchronism with control signals (φa, φb) and supply the selected output to a corresponding one of write data line (18). Since two data input buffers are used, each data input buffer may operate to sense every other input data and each of control signals (φa, φb) is set to have a pulse occurring in every two cycles of the input data.
