Title: A driving device for a stepping motor
IPC: G04C3/14
Filed: 1981-12-04
Abstract: A driving device of a stepping motor comprises a driver/detector circuit for detecting whether a rotor has rotated or not by comparing a voltage induced across a driving coil by the free oscillation of the rotor with a reference voltage after a driving pulse is cut off and a control circuit automatically varies the pulse width of the driving pulse in response to an output of the driver/detector circuit. The control circuit includes circuitry for lowering the reference voltage when the pulse width of the driving pulse is lengthened thereby enabling use of a wider range of driving pulse widths than would otherwise be possible.

Patent GB-2149260-A (GB)
Title: Image processing
Inventor: MCEWEN ROBERT KENNEDY
IPC: H04N5/217
Filed: 1983-11-04
Abstract: The more modern imaging systems employ solid state detector area arrays which "stare" at the viewed scene. The sensitivity and the output absolute value of the detector elements can vary very significantly over the array. In the invention the output of each individual detector element is normalised; specifically, there are found for each detector element the values defining its gain and offset, there are then recorded for each element the two factors that will convert each to the mean value of the entire array, and thereafter the relevant two "normalisation" factors are in use applied to the output of each element, before the output is employed to form the desired image of the viewed scene, so that the output is modified to the value it would have if it had emanated from an element having the predetermined average values for gain and offset. <IMAGE>

Title: Polarised relay of high sensitivity
Inventor: ELDRIDGE PETER GORDON
IPC: H01H50/10
Filed: 1984-11-07
Abstract: A polarised miniature electromagnetic relay has two changeover contact sets (12, 13) actuated by a pivotally mounted armature (7) which extends outside the energising winding (2). The energising winding has a fixed soft iron core providing a pole (6) at one end. The armature which is made of sheet metal has bent over end portions (8 and 9), one end portion (8) having mounted on its underside a thin, flat ferrite-loaded plastics magnet (14) which has a low energy and which is effective to polarise the relay. This arrangement has the advantage that two or more such relays can be mounted side by side without the biassing magnets interfering with adjacent relays, and a very compact design can be achieved, in contrast with prior art arrangements using a metal bar magnet. A four-changeover-contact set version is also described (Fig. 2). <IMAGE>

Title: Karman vortex flowmeters
Inventor: MIYOSHI NORIOMI
IPC: F02D41/18
Filed: 1985-02-05
Abstract: A flowmeter for measuring the quantity of air inhaled by an internal combustion engine comprises a signal processing circuit 25 for processing a detected vortex detection signal housed in a container 134 communicating via pipe 130 with an air inlet passage on the downstream side of a throttle valve (106, Fig. 32, not shown), the other side of container 134 being in communication with the atmosphere via pipe 132 so that an air flow will be induced through the container due to negative pressure on the downstream side of the throttle valve so that the components of circuit 25 will be cooled. The cooling air prevents a temperature rise of the elements of circuit 25 when the temperature within the engine compartment rises. <IMAGE>
