Abstract: A method and apparatus for rapid interconnection (hot plugging) peripheral device interface circuits to a computer bus is disclosed. The interconnections are completed using three sets of conductors in the sequence: common grounds, power from the bus and data lines. The time period between the interconnections is determined by the relative set back lengths of the conductors from the card edge and allows for stabilization of voltage and establishment of a stable high impedance state for the peripheral device controller circuits before the data lines are interconnected.

Abstract: A Phase Locked Loop (PLI) circuit (100) includes a control signal generator (20), a digital phase detector (28), logic gates (32,34), a charge pump (36) (charge/discharge circuit), a transmission gate (40), a loop filter (42), a lead-lag filter (44) and a voltage controlled oscillator (VCO) (46). Outputs of the digital phase detector are coupled through the logic gates to inputs of the charge pump. An output of the charge pump is coupled to a capacitor (38) and to a first input/output of the transmission gate. A second input/output of the transmission gate is coupled to an input of the loop filter whose output is coupled to an input of the VCO whose output is coupled to a first input of the digital phase detector. A second input of the digital phase detector is coupled to a source (18) of a reference frequency signal. The control signal generator generates non-overlapping complementary control signals with one of same connected to the logic gates and the other connected to the transmission gate. Accordingly, the electrical path from the digital phase detector to the charge pump through the logic gates is closed and the electrical path from the capacitor to the loop filter is open or vice versa. The loop filter includes an operational amplifier (54) with AC feedback which is controlled by the same signal which controls the logic gates. The PLL circuit is typically formed on a single integrated circuit silicon chip using CMOS technology.

Abstract: A laser Doppler anemometry apparatus comprises means (12,14,16,20) to create two coherent light beams which intersect to define a probe volume (18), and at least two sensors to detect light scattered in different directions by a particle traversing the probe volume. The light beams are orthogonally polarized; and each sensor comprises a beam splitter (30) arranged to split the scattered light into two orthogonally plane polarized components at 45° and 135°, and two photo-detectors (34) to detect these components. For a pair of photo-detectors the pedestal signals are the same but the Doppler signals are of opposite phase; the detected signals are added (to give the pedestal) and are subtracted (to give the Doppler). The Doppler frequency indicates particle velocity, while the phase difference between Doppler signals at the two sensors indicates particle size. The pedestal signals may be utilized as trigger signals.

Abstract: A disc driving apparatus comprises a motor (6), a turntable (9) which is rotated by a driving force of the motor and supports a disc on one side thereof, a fixed supporting portion for rotatably supporting the turntable, and magnetic means (20) for always generating a predetermined magnetic attracting or repulsive force between the other side of the turntable (20) and the fixed supporting portion which faces the other side of the turntable. A unidirectional urging force is always applied to the turntable by the magnetic means in the axial direction, so that even if an external vibration exists, when a force which is applied to the turntable by the vibration is equal to or less than the urging force, the turntable does not move in the axial direction. Thus, the interval between the disc supported on the turntable and a pickup does not change by the vibration, and an erroneous recording or reading of a signal can be avoided.

Abstract: A linear array of light emitting devices (e.g. LEDs) is disposed opposite to an array of corresponding photodetectors to define a gap through which the web travels. The web is scanned by sequentially applying pulses of electrical power to the emitting devices. Output signals are provided from each photodetector representing the presence of the web. In order that the brightness is sufficient to detect the presence of low density (semi-opaque) webs and to maintain uniformity of brightness of illumination from emitter to emitter, the current to the emitters is computer controlled by means of a control system. The control system responds to the signals from the photodetectors and increments or decrements the current from an initially preset level during selected scans, for example on scans which occur every 15 seconds. The preset level is sufficient so that the photodetectors detect a reduction in illumination and provide corresponding output signals even when blocked by a semi-opaque film.

Abstract: The invention relates to a cold water unit with performance adjustment to the heat generation of objects to be cooled with constant cold water forward run temperature, in which there is in the cold water foward run circuit a heat exchanger which is flowed through by coolant and which compensates the difference between cooling output and thermal output to be led away. Known cold water units are at the same time of very great constructional outlay. This outlay is reduced by the present invention in that the condenser (2K) of the cold water unit is at the same time that part of the heat exchanger (2W), present for regulation of the water temperature of the cooling water, which is flowed through by the cooling agent. <IMAGE>
