Title: Pulse-width-modulation method for providing extended linearity, reduced commutation losses and increase in inverter/converter output voltage
Inventor: BLASKO VLADIMIR
IPC: H02M7/219
Filed: 1992-08-17
Granted: 1996-09-17
Abstract: The invention relates to voltage conversion devices, whether for inversion (constant voltage to alternating voltage), or conversion (alternating voltage to constant voltage).  It includes a pulse-width-modulator and a three-phase, three-legged bridge, each leg of the bridge having a pair of complementary switches (S1/S1*, S2/S2*, S3/S3*). One of the switches S1, S2 or S3 (S1*, S2* or S3*) conducts in those time intervals where the associated reference voltage UA UB or Uc has a higher (smaller) amplitude than the other two reference voltages.   According to the  present invention, (a) three reference  voltages are supplied, (b) the maximum of these voltages is detected, (c) the maximum is subtracted from the peak value of a triangle wave used for forming the PWM signal, and (d) the difference is added to each of the reference voltages to form augmented reference voltages supplying a PWM, which in turn supplies PWM signals to a three-phase semiconductor bridge.   The result is that when one of the three reference voltages is greater than the other two, a switch of one of the three complementary pairs of such switches in the bridge conducts, while in each of the other two complementary pairs, both switches open and close in response to the PWM signal such that only two currents are independently controlled by each of the two complementary pairs which are allowed to open and close, and the third current, associated with the complementing pair which is not allowed to switch, is controlled by the other two.   Keeping one switch in each leg closed for one-third of the period of the reference voltage allows control of all three load currents to be dictated by the switching in only two legs.

Title: Phase-locked circuit capable of being quickly put in a phase-locked state
Inventor: ICHIYOSHI OSAMU
IPC: H03L7/087
Filed: 1992-09-29
Granted: 1996-07-02
Abstract: In a phase-locked circuit which is operable in response to an input complex signal to produce an output complex signal, a first complex multiplication is carried out between the input and the output complex signals to obtain a phase difference therebetween which appears as a complex phase difference. The complex phase difference is composed of a real part and an imaginary part which are individually allowed to pass through a low pass filter and to be supplied to a numerically controlled oscillator as a control signal.  The control signal includes a frequency component even when the phase-locked circuit is put into an asynchronous state.  The low pass filter may be replaced by a digital circuit comprising phase dividers.

Title: Low pressure tubing quick connector
Inventor: MCNAUGHTON JAMES
IPC: F16L37/084
Filed: 1992-11-18
Granted: 1999-03-23
Abstract: An improved fluid connector has a deformable axially outer ring  with  latches  which  retain  a  tube  within  a main  body  of  the connection.  The outer ring is oval in cross-section, with the latches extending along surfaces spaced across the minor diameter of the oval. Connection  portions  connect  the  outer  ring  to  a main  body  of  the connector.  The connection portions extend from locations spaced across the major diameter of the oval shape.  An upset portion of  the tube deforms the latches radially outwardly upon insertion.  A removal force may  be  directed  radially  inwardly  of  the  outer  ring  at  locations adjacent to the connection portions to cause the latches to bow radially outwardly and allow the tube to be removed from the connector.   The inventive connector bears the removal force on the relatively thicker connecting  portions,  and  requires  flexing  in  the  relatively  thinner outer ring.

Granted: 1999-06-29
Abstract: A package is provided for an integrated circuit comprising a dielectric body enclosing the integrated circuit chip having a plurality of conductive terminal members extend through the dielectric body.  The dielectric body includes a magnetic shielding layer for electromagnetic radiation from the integrated circuit.  The magnetic shielding layer comprises a material having a high magnetic permeability and a high resistivity, so that the dielectric body absorbs electromagnetic radiation at frequencies generated by the integrated circuit and thereby attenuates electromagnetic emissions from the integrated circuit.  Suitable materials having a high dielectric constant and high magnetic permeability include ferrites. Conveniently a shielding layer of ferrimagnetic material comprising a ferrite plate may be applied to surfaces of a conventional plastic or ceramic packaging material. Alternatively, ferrite particles may be incorporated into binder to form a composite material suitable for forming into an IC package.  The magnetic nature of the shielding provides that a non-conductive dielectric package may significantly attenuate and suppress electromagnetic interference generated by an enclosed IC.  Further to provide effective electromagnetic shielding for a large apparatus, individual packages may be customised to provided shielding to particular integrated circuit chips with higher emissions, thereby reducing the total cost of shielding an electronic system or apparatus.
