IPC: H04L25/03
Filed: 1989-11-09
Abstract: In a digital demodulator, a recovered baseband signal is sampled in response to a clock pulse supplied from a VCO and converted to a digital signal representing one of multilevels of the sampled signal. Real-axis and imaginary-axis transversal equalizers are provided. Each equalizer has a tapped delay line for receiving the digital signal, a plurality of tap weight multipliers connected respectively to taps of the tapped delay line, and an adder. The adder of the real-axis transversal equalizer sums all outputs of the tap weight multipliers except for the output of one which is connected to a tap adjacent to the center tap for producing a partially equalized signal, while the adder of the other equalizer sums all outputs of the tap weight multipliers for producing a fully equalized signal. Both of the equalized signals are summed by an adder and applied to a phase control circuit which derives from it a VCO control signal so that it corresponds to a tap-weight control signal applied to the multiplier whose output is excluded from being summed by the adder of the real-axis transversal equalizer. The output of the adder is summed with the excluded multiplier output and supplied to a tap weight controller which controls the multipliers of both transversal equalizers.

Abstract: A germicidal iodine containing composition includes iodine, an iodophor, cupric ions and nitrite ions in an aqueous base. Iodide ions which form in the composition during radiation sterilization or prolonged shelf life are oxidized back to iodine by the cupric ions in a pH dependent reaction which consumes hydrogen ions formed concurrently with the iodide ions. Cuprous ions formed during the oxidation are spontaneously cycled back to cupric ions by traces of air present in the composition. The composition may include nitrite ions to augment the conversion of cuprous ions back to the cupric form.

Abstract: In an electronically controlled automatic transmission system including a gear transmission (5) and a clutch (4), in which a target gear position is determined in accordance with map data for gear shift control, it is discriminated whether or not the vehicle is in accelerating condition and necessary control for shifting up the transmission to the target gear position is carried out only when the vehicle is not in the accelerating state. Thus, when the driver presses hard on an accelerating member (15) to accelerate the vehicle, a series operations for shifting up is not carried out, whereby the transmission is kept in its present gear position. The operation for shifting up can be carried out after the completion of the acceleration of the vehicle.

Abstract: The invention relates to a straightness interferometer system, for measuring transverse deviations in the relative movement of machine parts. The preferred embodiment comprises a laser 30 which directs a single frequency laser beam, polarised in two orthogonal modes, along a principal axis P onto a beam splitter 24 which splits the beam into its two modes to provide two secondary beams 26,28. One of the secondary beams 26 is undeviated from the principal axis, the other 28 is deviated through a small angle. A roof-top reflector/prism combination 30/40 is positioned in the paths of both secondary beams in a plane normal to the principal axis, the prism being arranged to deflect the deviated beam into a direction parallel to the pincipal axis so that both beams are reflected back to the beam splitter where they re-combine to form a combined beam. The combined beam is passed to a detector system 38 for detecting interference fringes reproduced from the combined beam caused by relative change in the path lengths of the two secondary beams as the reflector undergoes movements transverse to the principal axis. 
     Three types of beam splitter are specifically disclosed, two of which show a further preferred feature of displacing one of the beams transversely to solve the dead path problem of a prior art system. A variety of combinations of the various elements of the preferred system are discussed but not all are illustrated.

Abstract: An ultrasonic rotary horn (10) intended to be excited at a frequency of from about 18 to about 60 kHz, which horn is shaped, solid metal object having a radial surface (11) terminated by a first end (12) and a second end (13), and a rotational axis (14), in which each of the ends is defined by a surface. The diameter of the horn can vary from about 4 cm to about 19 cm. The width of the horn at the radial surface is in the range of from about 0.6 cm to about 13 cm. The thickness of the horn at its rotational axis is from about 0.6 cm to about 15 cm and is independent of the width of the horn at the radial surface. The horn has a mass in the range of from about 0.06 kg to about 30 kg. The diameter, width, and thickness values are selected for a desired frequency so that the horn, upon being excited by ultrasonic energy at such frequency which is input at the rotational axis at, and substantially perpendicular to, one or both ends, is adapted to resonate in a manner such that:
     (1) the excited end moves substantially in phase with the movement of the source of excitation;   (2) the opposing end, whether or not it is actively excited, moves substantially out of phase with the movement of the excited end;   (3) said radial work-contacting surface also moves substantially out of phase with the movement of the excited end; and   (4) said horn exhibits a single nodal point at its geometric center.    The horn may include hubs on each of the two ends; the hubs being integral parts of the horn; the horn may also include threaded studs which protrude from the ends or from the hubs. The ultrasonic rotary horn of the present invention is particularly useful in continuous processes for bonding together two or more layers of at least partly thermoplastic materials, such as woven and nonwoven fabrics and films.
