Patent GB-2273201-A (GB)
Title: High reliability contact scheme
Inventor: PUNTER GEORGE WILLIAM
IPC: H01L23/528
Filed: 1992-09-18
Abstract: A high reliability contact scheme is provided for electronic devices such as heterojunction bipolar transistors used in cell phones. A multilayer contact scheme is etched and patterned to produce an upper level (26) of power resistance conductor material, such as gold, contacting a lower barrier layer (14) of higher resistance material through an interviewing insulating layer (16) of air or inorganic or organic material. The higher resistance material may be titanium, palladium, germanium, indium, titanium tungstenate, tungsten silicide or an alloy of any of these. A direct interface between the lower resistance conductor material and the semiconductor material of the transistor is thus eliminated. <IMAGE>

Title: Determining the stator flux of an asynchronous machine
Inventor: HEIKKILA SAMULI
IPC: H02P21/12
Filed: 1992-10-21
Abstract: The invention relates to a method for determining the stator flux of an asynchronous machine when a stator current (is) and stator voltage (us) of the asynchronous machine are measured, wherein the product of the stator current (is) and a stator resistance estimate (Rse) is determined (at 30), the obtained product is subtracted at 31 from the stator voltage (us) and the obtained voltage difference is integrated at 32 with respect to time to obtain a first stator flux estimate ( PSI se). The method further comprises the steps of determining (at 33) a second stator flux estimate ( PSI se,id) on the basis of the stator voltage (us) the stator current (is), the short-circuit inductance ( sigma Ls), the stator inductance (Ls) the rotor time constant ( tau r) and the stator resistance estimate (Rse); determining at 34 a stator flux correction term ( DELTA  PSI se) as a difference between the first stator flux estimate ( PSI se) and the second stator flux estimate ( PSI se,id) and summing at 36 the stator flux correction term ( DELTA  PSI se) weighted by a constant coefficient (w) with said voltage difference. The method is particularly useful at very low operating frequencies and is accurate over both short and long periods of time. <IMAGE>

Title: Light modulating cells
Inventor: DAWBER WILLIAM NICHOLAS
IPC: G02F1/29
Filed: 1993-03-18
Abstract: A light modulating cell comprises an electro- or magneto-optically active medium (13), such as a lithium niobate crystal, through which a travelling electromagnetic wave (12) is transmitted to thereby generate a moving phase grating in the medium. Light (14) is transmitted through the medium and, after modulation by the moving phase grating therein (17) is detected by an optical detector. The modulation cell comprises parallel plates (10, 11) connected to a waveguide; the electro- or magneto-optically active medium being located within the enclosure and means being provided to direct light to the medium and to detect light diffracted by the medium. A radio frequency electrical signal connected to the waveguide produces the moving phase grating in the optically active medium. The crystal is cut such that its crystal axis is colinear with the direction of the electromagnetic waves (12) traveling therethrough and light is transmitted laterally between the plates. The crystal is selected to have a high diffraction efficiency and a high time-bandwidth product. In an alternative arrangement the active medium is formed of a layer (34) of crystal material of relatively high dielectric constant sandwiched between layers (35, 36) of crystal material of a relatively low dielectric constant where the crystal axis of the middle layer (34) is perpendicular to the crystal axis of the outer layers. <IMAGE>

Title: A vehicle security device with electronic use-authorization coding
Inventor: BRINKMEYER HORST
IPC: G06F21/62
Filed: 1995-03-28
Abstract: Vehicle security devices with electronic immobiliser are known in which the code protection is based for example on a unidirectional changing code method or a bidirectional symmetrical encryption method. Systems which operate bidirectionally offer a higher degree of protection against the misuse of intercepted authentication data but until now have been costly. 
<??>The new vehicle security device contains a rapid encryption method which operates on the basis of a one-way function, for which method at most it is necessary to store one item of secret code information at the vehicle end in a single piece of equipment of any desired number of pieces of equipment involved in security while in all these units only the one-way functional values corresponding to these inverse image values need to be present, the reading out of which inverse image values does not permit unauthorised production of a counterfeit key. Security against interception and storage of information transmitted at the key end in order to produce counterfeit keys is ensured by including in this authentication information an item of random information transmitted from the vehicle end. 
<??>To be used in realising electronically actuable locking systems and/or electronic immobilisers.

Title: Protecting a flat cable joint
Inventor: TANAKA YOSHIYUKI
IPC: B29C45/14
Filed: 1996-02-15
Abstract: A method of protecting a conductive connecting part of a flat cable and a protecting structure of the cable are provided. The method includes a step of connecting conductors of the flat cable to conductors of relay wires at the conductive connecting part, a step of arranging a protective member at the exterior of an insulating cover part of the flat cable, a step of interposing the protective member between opposing molding dies and accommodating the conductive connecting part of the flat cable in a cavity defined by the molding dies, in a leak-tight manner and a step of supplying insulating material in the cavity for an insert molding. The protecting structure includes the conductive connecting part, the protective member and the insulating member for enclosing the conductive connecting part together with a leading end of the protective member. The insulating member is formed by the insert molding. Since the cover part is not held by the mold directly but held through the intermediary of the protective member in forming the conductive connecting part, it is possible to moderate a force applied on the conductors by the aid of the protective member without increasing a thickness of the cover part of the flat cable, so that the breaking of the conductors can be prevented certainly.

Filed: 1996-12-24
Abstract: A vehicle braking system comprising a return pump (40, Figure 1) arranged in a hydraulic circuit with a magnetic valve (53) is monitored in the following way. If the vehicle forward speed Vx lies between Vmax, Vmin, and the brake light switch is OFF, the pump is switched ON by a control unit, and then switched OFF when the pump speed Np reaches Nhigh. The time T1 taken for the pump to slow to a preset value is recorded. The magnetic valve is now switched to OPEN, and the above steps are repeated, with the time T2 for the pump to slow down being recorded. It is determined if T1-T2<S. If so, a fault is indicated, and an error is displayed (14) and/or antilock control, drive slip control, or travel dynamics control is switched off. It is possible to test that fitting of the control unit and the valve/pump unit (29) separately in a workshop has been carried out correctly.
