摘要： An apparatus for training horses having a series of adjustable obstacles with transverse crosspieces (22; 201; 306; 402; 510), the apparatus comprising a base structure formed by a pair of substantially horizontal and parallel guide rails (2, 2'; 108; 102') disposed on the ground at a predetermined distance from each other, a plurality of vertical mounts (3, 3'; 101, 101'; 203, 203'; 304, 304'; 501) slidably placed upon the guide rails to adjust their longitudinal position therealong. The vertical mounts have vertically mobile supports for supporting and holding the crosspieces at adjustable height. The same number of vertical mounts is disposed on both rails in mutually facing relationship to form pairs, each vertical mount being fixed on a wheeled carriage coupled to first motor means to provide synchronous movement of the pairs along the guide rail. Second motor means act on the vertically mobile support to adjust their vertical position along the guide means.

摘要： A reinforced flexible hose includes at least one inner tubular layer (2) of plastic or rubber; a knitted reinforcement (3), which has substantially parallel rows (4) and lines (5) of substantially parallel stitches, with respective stitch counts per unit length of the hose (Nm, Nr); and an outer layer (6) which is superimposed on the reinforcement layer (3) to protect it. The knitted reinforcement layer (3) is provided in the form of a single tubular layer and is wrapped around the outer surface of the inner tubular layer (2); the rows (4) and lines (5) of stitches are substantially helical, with respective longitudinal pitches (Pm, Pr) and inclinations which are mutually opposite with respect to the longitudinal axis (Y). The longitudinal pitch (Pr) of the lines (5) of stitches is substantially proportional to the square of the outside diameter (ζo) of the inner layer (2), whilst the number of lines (Nr) of stitches per unit length of the hose is directly proportional to the outside diameter (ζo) of the inner layer (2).

摘要： A motorized head for multiple-head machines for twisting threads or for similar processes includes: a supporting pivot (2) for a thread spindle or reel (3); a rotor (5) that is coaxial to the pivot for unwinding and twisting the thread; a motor connected to the rotor to make it rotate at a controlled speed. The motor consists, for each head, of a single electric motor (8) of the high-efficiency brushless type with cylindrical permanent magnets, directly coupled to the rotor (5). An electronic circuit (11) for speed and power supply control, independent of the circuit of other heads, is associated with the motor. The motor speed and power supply control circuit (11) is a miniaturized frequency converter that is integrated in the motor shell.

摘要： A temperature compensated logarithmic detector biased with a proportional to absolute temperature (PTAT) voltage produced in accordance with an area ratio of biasing transistors is disclosed. According to one implementation of the invention, the temperature compensated logarithmic detector includes biasing circuitry (12) and a logarithmic detector cell (14). The biasing circuitry receives an input signal and produces a PTAT bias voltage from the input signal. The PTAT characteristic of the PTAT bias voltage is produced by an area ratio. The logarithmic detector cell converts the input signal to a logarithmic output signal in accordance with a logarithmic transfer function over a narrow range.

摘要： A linear differential amplifier (48) with improved voltage swing is disclosed. The linear differential amplifier (48) corrects for an error voltage inherent in differential pair amplifiers, without hindering the available voltage swing, and thus, is particularly suited for low-voltage applications. The differential amplifier includes an input differential amplifier (50) for receiving an input voltage difference to be amplified; a distortion correction differential amplifier (52) for producing an error correction amount; and an output differential amplifier (54) for receiving the input voltage difference and the error correction amount, amplifying the input voltage difference to produce an output voltage, and correcting the output voltage in accordance with the error correction amount. Also disclosed is a method for improving available voltage swing of a differential amplifier when amplifying an input voltage difference.
