Title: Control unit for regulation of washing machine motors
Inventor: SOLE MARCELLINO SAMSO
IPC: H02P7/295
Filed: 1988-02-15
Abstract: A control unit for regulating the speed of a washing-machine motor 1 over a wide range of speeds (e.g. in the wash, rinse and spin modes) comprises a tachogenerator 2 coupled to a divider 6 for dividing the output pulses of the tachogenerator according to the operating mode of the machine. The pulses, after being differentiated at 9 are fed to a voltage/time converter 11 which compares the voltage on a charging capacitor with a reference to produce a measure of the pulse interval. The output of the converter 11 is integrated at 15 and compared at 16 with a saw-tooth waveform to control a triac 19 through which the motor 1 is supplied. A memory 13 may be used to trip the supply to the motor if an excessive speed is sensed. <IMAGE>

Title: Pulsed plasma apparatus
Inventor: HEINECKE RUDOLF AUGUST HERBERT
IPC: C23C16/515
Filed: 1986-06-27
Abstract: An apparatus for pulsed plasma processing of a substrate surface includes a reactor chamber 11, a high power radio frequency pulse generator 12 whereby, in use, a substantially fully dissociated localised plasma is generated in the chamber, means for evacuating the chamber 17, means for supplying active or inert gases to the chamber, and means for traversing the plasma across the substrate surface whereby, at a given instant, only part of the substrate surface is in contact with the plasma. Two types of traversing or scanning are envisaged, one where the treated area and the high intensity plasma regime are mechanically moved with respect to each other, and another where scanning is provided by switching the r.f. power between a plurality of electrodes as shown in Fig. 9. Alternatively a rotating shield with a sector- shape opening lined with magnets mounted in front of an electrode may be used. <IMAGE>

Title: Balanced constant current feed for subscriber lines
Inventor: DYER MICHAEL PHILIP
IPC: H04M19/00
Filed: 1988-11-11
Abstract: A telephone subscriber's line circuit has a transformer (TF) which does not carry DC, as its line-side winding is split with a mid-placed capacitor (C). The two legs of the line are each coupled to the DC terminals (0-50V) via current regulators (CR1, CR2) each preferably shunted by a high value resistor (Rs) which provides balance if the regulators are not identical. Results are best if the regulators, which may be commercially available constant-current devices - have positive temperature coefficients of pass current. <IMAGE>

Title: Full-swing BiCMOS driver
Inventor: YUN BYUNG WHEE
IPC: H03K17/567
Filed: 1990-10-15
Abstract: A full-swing BiCMOS driver comprises an inventor 11 for inventing an input signal VIN, a pull-down controlling part 2 for providing control signals, an output driving part 3 for providing an output, and a delay-inventor Dl for delaying and inventing the input signal between the input terminal and an output terminal.

The transmission gates may be replaced by other resistance arrangements and the delay is introduced by a combination of the resistance of the resistors with the parasitic capacitance of the following transistor. The BiCMOS driver is applicable to logic gates such as AND, NOR. <IMAGE>

Title: Air-fuel ratio learning control system for automotive vehicle
Inventor: MOROZUMI TAKURO
IPC: F02D41/14
Filed: 1990-11-06
Abstract: An air fuel ratio control system provides a basic fuel injection quantity and has a feedback loop providing a limited range of correction to the basic quantity in dependence on the output of an exhaust gas oxygen sensor. Under normal circumstances the feedback loop provides a compensation signal a depending on proportional and integral error and causes the air fuel ratio to oscillate around the optimum level. In the event of a large discrepancy between the optimum and the actual air fuel ratio, the cessation of oscillation is detected over a time interval t0 and a second correction factor, the learning value, is steadily increased to assist the return of the air fuel ratio to the optimum. While the learning value changing, the integration coefficient Ki in the feedback loop is reduced in value to limit the change in the compensation signal a. When the air fuel ratio returns to optimum, the recommencement of oscillation is detected over a predetermined number of cycles and any further correction  DELTA  alpha  in the compensation signal a is transferred to the to, learning value. <IMAGE>

Title: Automatic selector device of a change-speed gear box includes gear ratio retention control valve
Inventor: MULLER ALFONS
IPC: F16H61/02
Filed: 1992-07-15
Abstract: In an automatic selector device of a change-speed gearbox of a motor vehicle, a frictional connection such as a clutch or brake which can be engaged and disengaged by means of a gear ratio retention control valve 11 is held in the instantaneous position on the occurrence of a fault in an electronic control unit 8. An auxiliary control force for actuating the gear ratio retention control valve 11 is derived from the magnetic force of an electromagnetic control valve 9 for the gear change, this valve being dependent on the control unit 8, the control force resulting from a permanent minimum excitation of the electromagnetic valve. The control pressure resulting from the minimum excitation is less than the force of a spring 19 acting to move a selector valve 7 into a zero position in which working pressure is cut off from a selector setting element which actuates the brake or clutch. <IMAGE>

Patent GB-2257867-A (GB)
Title: Tracking radar system
Inventor: ATTWOOD JOHN WILLIAM
IPC: G01S13/68
Filed: 1989-07-27
Abstract: A tracking radar system (Figs 2 and 3 not shown) has a multi-element aerial (1). A receiver (10) processes radio-frequency sum (S) and difference (D) signals derived from the aerial to produce corresponding intermediate frequency sum (S<1>) and difference (D<1>) signals. The oscillator (62) of a phase-locked loop (60) locks on to the frequency of the intermediate frequency sum signal (S<1>), and a phase-sensitive detector (34) compares the oscillator (62) output with the intermediate frequency difference signal (D<1>) to produce an output signal representing the direction of a target relative to the aerial. The phase-locked loop includes a variable gain circuit (300). Responsive to the intermediate frequency sum signal (S<1>), a threshold detector (304) produces a first or second output signal. The first threshold output signal is combined with a target acquisition signal to cause the variable gain circuit (300) to slowly decrease the bandwidth of the phase-locked loop (60). The second threshold output signal causes the variable gain circuit (300) to rapidly increase the bandwidth of the phase-locked loop (60). The invention is particularly concerned with the use of sidebands added to the narrowband oscillator (62) output to simulate the sidebands in the wideband sum signal I.F. As shown the narrow band intermediate frequency sum signal from oscillator 62 is combined at 605 within the first phase locked loop with a proportion of the output of a second wide band phase locked loop 600-603 to provide pseudo sidebands of constant amplitude. <IMAGE>
