Title: Over write capable magnetooptical recording medium with controlled exchange coupling force between magnetic layers
Inventor: IIDA HARUHISA
IPC: G11B11/105
Filed: 1989-08-02
Abstract: An over write capable magnetooptical recording medium comprises a substrate, and a magnetic film including first and second layers stacked on the substrate and having perpendicular magnetic anisotropy, wherein a non-magnetic element is doped in one having a smaller product of a saturation magnetic moment Ms and coersivity Hc of the first and second layers, thereby controlling an exchange coupling force  sigma w acting between the first and second layers to a predetermined value. The preferred non-magnetic element is Si, Ge, Ti, Cr, Cn or In, giving a medium which permits reversal of magnetization in the second layer with recording of a bit information of magnetization of the first layer under the influence of the second layer magnetization, under high level laser radiation whilst under low level laser a bit information is recorded in the first layer under the influence of the second layer. The layers have differential Curie temperatures and coercivity.

Title: Swept frequency signal generating circuit
Inventor: BRAITHWAITE IAN
IPC: G01R23/173
Filed: 1989-09-13
Abstract: A swept frequency signal generating circuit for use as the first local oscillator of the superheterodyne receiver of a spectrum analyser, comprising: an oscillator 13 for generating the output signal; an arrangement for generating from a memory (not shown) a frequency control signal to tune the oscillator, the control signal being swept periodically over a predetermined range, a mixer 14 for mixing the output signal with a synthesised signal source 15 output to generate a difference frequency signal; an arrangement 17-19, 21, 22 for detecting the instant that the difference frequency crosses over a datum frequency; and an arrangement 20 responsive to the detecting arrangement and to the values of the datum frequency and the frequency of the synthesised signal source to provide an indication of the precise frequency of the output signal at the said instant of cross-over. A microprocessor 20 uses the cross-over frequency as a reference datum, determines the amplitude/frequency spectrum of an input signal and displays it. Two or more frequency cross-overs may be obtained by arranging the sources 15, 22 to be agile. For narrow sweeps, the oscillator 13 may be briefly controlled in a phase lock loop arrangement by applying to the oscillator 13 via a switch 25 the output of a phase comparator 21. <IMAGE>

Title: Laser doppler velocimeter
Inventor: DRAIN LESLIE ERNEST
IPC: G01S7/481
Filed: 1990-08-13
Abstract: A laser beam (14) is split into two accurately parallel output beams (18), and the beams are focussed to intersect at their common focus. The beam (14) is split by a spaced-apart pair of calcite wedges (46), and by Brewster-angle displacement blocks (50, 52) with accurately parallel opposite faces. A lens assembly causes the beams to intersect at an angle of up to 60 DEG , and the light beams emerge from the final surface of the assembly along radial lines, so the position of the crossing point is unaffected by immersion of that surface in a liquid such as water. A probe volume as small as 15 micrometres diameter and 30 micrometres long in water can thus be achieved. <IMAGE>

Title: Traction control apparatus for motor vehicles
Inventor: TAMURA MINORU
IPC: F02D45/00
Filed: 1991-02-14
Abstract: Wheel slip in the driven wheels (1L, 1R) of a motor vehicle is detected by comparison between driven wheel speed and nondriven wheel speed. in the event that slip is detected the driving force is reduced by reducing fuel supply or applying brakes. In the event of wheel slip occurring during cornering, resulting in lateral slip of the vehicle, the driving force reduction is inhibited, allowing driving wheel ship to continue thereby increasing lateral stability of the vehicle. Lateral slip is detected by comparing rates of change of wheel speed against a threshold. If the undriven rear wheels are decelerating faster than the threshold value, and the driven front wheels not decelerating so fast, or accelerating, lateral slip is indicated. Lateral slip may also be detected by a yaw sensor. <IMAGE>

Title: A reverse gear selection inhibitor arrangement and inhibitor therefor           comprising pivoting cam plate
Inventor: HOWARD TIMOTHY M
IPC: F16H61/18
Filed: 1993-06-03
Abstract: A reverse gear selection inhibitor arrangement for a motor vehicle gearbox comprises a selector finger and a reverse gear selection inhibitor comprising a cam-plate 41 mounted for example on the base 19 of a gearlever housing for pivotal movement in two opposite directions. The pivotal axis of the cam-plate 41 is off-set from the principal longitudinal axis of the selector finger in the central neutral position by a linear distance. A cam shoulder 46 on the cam-plate 41 is positioned at a distance from the pivotal axis greater than said linear distance. The cam-plate 41 is sprung biassed towards an at-rest position. The selector finger in travelling from a forward gear position v to a reverse gear position contacts one face 47 of the shoulder 46 causing pivotal movement of the cam-plate 41 but such movement is stopped when faces 22 and 21 respectively on the cam-plate 41 and base 19 of the housing 14 abut one another thereby preventing the reverse gear position R being reached directly from the forward v position and stopping the selector portion 8 at the selection neutral position. During pivotal movement, the cam-plate does not cut the selector finger axis. <IMAGE>
