Abstract: La présente invention a pour objet un mécanisme de verrouillage monté entre la partie dossier et la partie siège d'un ensemble de siège d'automobile, le mécanisme en question permettant de contrôler le pivotement de la partie dossier par rapport à la partie siège de l'ensemble. Un organe de montage est associé à chacune des pattes avant et arrière de l'ensemble de siège, chacun des organes de montage en question pouvant être actionné en coopération avec son élément de fixation respectif ancré au plancher du véhicule afin de permettre le déplacement de la partie siège de l'ensemble entre une première position d'utilisation à l'intérieur du véhicule et une deuxième position de rangement à l'intérieur du véhicule. L'organe de montage associé à l'une, au moins, des pattes arrière du siège comporte en outre un mécanisme de verrouillage pouvant être verrouillé ou déverrouillé de son élément de fixation respectif. Un premier dispositif de manoeuvre monté sur le côté du siège peut être actionné par l'utilisateur entre une position neutre, où un organe de verrouillage s'oppose au pivotement de la partie dossier du siège, et une position de manoeuvre, où la partie dossier peut pivoter librement par rapport au siège. Un deuxième dispositif de manoeuvre monté sur la partie siège de l'ensemble est disposé de manière à être actionné par une partie du dossier du siège lorsque celui-ci est rabattu vers l'avant de l'ensemble, ce qui a pour effet de dégager les organes de verrouillage et d'autoriser le coulissement vers l'avant de la partie siège de l'ensemble entre sa position d'utilisation et sa position de rangement pendant que le dossier poursuit son mouvement de pivotement par rapport à la partie siège de l'ensemble.

Abstract: On a rotor which is fixed to a rota-table rotating shaft, a plurality of permanent magnets are disposed along the direction of rotation such that the same magnetic pole type thereof face outward.  In the same way, balancers are disposed on the rotor for balancing the rotation of this rotor.  Each of the permanent magnets is obliquely arranged with respect to the radial direction line of the rotor.  At the outer periphery of the rotor, an electromagnet is disposed facing this rotor, with this electromagnet intermittently energized based on the rotation of the rotor.          According to the magnetic rotating apparatus of the present invention, rotational energy can be efficiently obtained from permanent magnets.  This is made possible by minimizing as much as possible current supplied to the electromagnets, so that only a required amount of electrical energy is supplied to the electromagnets.

Title: Method and apparatus for scrambling and descrambling of audio signals
Inventor: QUAN RONALD
IPC: H04B15/00
Filed: 1994-10-18
Granted: 2000-10-17
Abstract: Audio signals are descrambled by double sideband modulating the scrambled audio signal with a modulation carrier having a carrier frequency slightly above the highest audio signal present in the scrambled studio. This produces a double sideband signal that is passed through a low pass filter which in turn is modulated by a second carrier frequency lower than the first carrier signal by an amount equal to the offset spectrum of the original scrambled signal. The first low pass filter nulls out any residual carrier from the first modulator that results from the intermodulation of the two modulation frequencies that would be audible at its descrambler output. The modulators used are low noise switch type modulators that improve the signal to noise ratio in the descrambled signal over the previously used linear modulators. The use of switch type modulators provides a lower cost device with improved performance. A companion scrambling device uses similar technique to provide improved performance at a lower cost.
