Abstract: Un transducteur optique permettant de déterminer la distance ou le déplacement d'un miroir (3) comprend une diode laser (1) qui est excitée à intensité constante. On analyse le spectre du signal de tension dans ladite diode laser, et on calcule l'écartement entre elle et le miroir (3) à partir de la formule f = cm/2L, où f est la fréquence, c la vitesse de la lumière, m le numéro du mode et L la longueur optique efficace de la cavité. Une force, ou un autre transducteur, peut être couplée au miroir (3), ce qui permet de calculer ladite force ou d'autres paramètres. Dans un autre mode de réalisation, on amène par une fibre optique le faisceau laser à une cavité optique éloignée, de longueur variable, et on calcule les fréquences dans ladite cavité en analysant le signal de tension dans la diode laser.

Abstract: L'invention concerne un élément pivotant destiné à des radiotéléphones portables et est configuré spécialement pour assurer un couplage extrêmement efficace de l'énergie acoustique entrant dans et sortant du radiotéléphone grâce à un pavillon acoustique formé de manière précise et constitué de la cavité intérieure de l'élément plan pivotant. Lorsqu'il est conçu comme dispositif de couplage de l'énergie acoustique dans un microphone monté de manière fixe sur le boîtier du radiotéléphone, le son incident est dirigé de l'embouchure du pavillon vers la section de la gorge, puis au travers d'un joint acoustique rotatif vers un canal d'entrée sur le microphone. Le joint rotatif pouvant tourner en continu s'adapte aux rotations de l'élément pivotant, ceci ayant pour conséquence de donner à l'élément pivotant deux fonctions, à savoir celle de protection et de recouvrement du clavier du radiotéléphone lorsqu'il n'est pas utilisé, et celle de couplage efficace du son entrant lorsqu'il est déployé.

Abstract: Metal members are joined to each other by the use of depending collars and through holes. A tool head inserted through the collars and holes and the tool shoulder exert pressure to simultaneously bend and crimp the collar. This technique can also be applied to truss members or to tracks and studs so that the members are easily joined or attached to each other. Beveled ends facilitate the alignment of collars with the holes.

the belt straps, a pair of plastic tongues, each
attached to one of the other two belt straps and
inserted, for fastening purposes, into the shell on top

by elastic means, engage with the tongues when the
latter are pushed into the shell, holding them firmly,
and a release button able to move between a rest
position and a working position, into which it is
pushed manually, against the action of the elastic
means, and disengages the retention means from the
tongues, while an elastic ejection member, which is
preloaded by the insertion of the tongues,
automatically ejects the latter.

is able to move in a guided manner (in 11.3) relative
to the said shell (11) and carries an integral metal
pawl (14) that engages with the said tongues (12), the
latter being inserted into the shell (11) on top of
each other, by moving in a plane approximately
perpendicular to the direction of insertion of the
tongues, and keeps the parts securely engaged by the
return action of the said elastic means (15), which
push the said release button (13) into its rest
position.

Title: Ferroelectric material, nonvolatile  memory device and their manufacturing methods
Inventor: MACHIDA AKIO
IPC: H01L21/314
Filed: 1998-05-14
Abstract: It is intended to provide a ferroelectric that exhibits
superior ferroelectricity. A ferroelectric provided is an
oxide having a layered crystal structure that is composed of
Bi, a first element Me, a second element R, and O. The first
element Me is at least one element selected from the group
consisting of Na, K, Ca, Ba, Sr, Pb, and Bi. The second
element R is at least one element selected from the group
consisting of Fe, Ti, Nb, Ta, and W. Ninety-eight percent or
more of the entire body of the ferroelectric exhibits
ferroelectricity. After an oxide having a layered crystal
structure has been grown by a vapor-phase method (crystal
growth step), electrodes are attached to the oxide having a
layered crystal structure and a voltage is applied thereto
(voltage application step). As a result, strains of crystal
lattices are corrected at least partially, whereby portions
that did not exhibit ferroelectricity at all or did not
exhibit superior ferroelectricity due to such large strains
that the symmetry of crystal lattices is lost are changed so
as to exhibit superior ferroelectricity.

Abstract: The lambda probe testing method involves using an air source (11) for individually supplying air to at least two lambda probes (7,8,9,10). The probes are inserted in respective exhaust gas lines (3,4) of a multi-cylinder IC engine, during a test interval corresponding to a reaction interval of the lambda probe. The resulting lambda probe signal is compared with a threshold value. The air is supplied to each lambda probe via a connection (12,13,14,15) to the exhaust gas line between the exhaust gas outlet (16,17) of the engine and the lambda probes.

Abstract: The spray gun has an air cap (22) that generates a spray mixture of
liquid and air. The air cap (22) includes a fluid valve (14) for
controlling the delivery of liquid and a separate air valve (12) in the
body of the spray gun is provided for controlling delivery of air. A
control mechanism assembly (16,18,56) for both of the valves (12,14) is
located axially within a central bore (48) extending substantially the
length of the spray gun. The control mechanism is actuated by means of a
cam and follower arrangement with the cam surface (11) provided on the
rear of a manually operable trigger (10). The fluid valve (14) is fully
adjustable separately from the air valve (12) but the control mechanism
assembly includes a common control member (18) that is in engagement
with the control mechanism and operates both the fluid and air valves.
The arrangement of the air valve (12) enables the surface area of the
air passages (34,70) leading from an ionising source (72) to the air cap
(22) to be minimised and unnecessary restrictions to be omitted so that
ion recombination losses within the spray gun are significantly reduced.

Abstract: To break down continuous textile materials (3) into fibers, they are subjected to high pressure fluid streams as a continuous fluid curtain (14) over the whole width of the material and at least on one side, delivered by a wide slit jet (6). The fluid is delivered by the wide slit jet (6) at a pressure of 25-70 bar. At the fluid beating station (4), where the pressure fluid jet stream strikes the fabric (3), the material is supported by a smooth and impermeable surface pref. as a rotating roller (1). The fluid enters the jet (6) through connections on both sides, impelled by a recirculating pump. The gap between the jet (6) and the material (3) is not more than 20 mm and preferably not more than 8 mm. The fluid is pref. water, with additives especially to swell cellulose and other natural material fibers and mixed with air. The water jet stream strikes the fabric (3) at an angle ( alpha ) of 40-150 degrees and pref. 60-120 degrees . An Independent claim is included for an apparatus with a wide slit jet (6) to form a continuous fluid curtain (14) on the running textile material (3).
