Abstract: A circuit includes a receiver having first and second differential input pairs and one differential output pair, the receiver outputting the first differential inputs at the differential outputs in a first mode and applying test signals to the second differential inputs and outputting the second differential inputs at the differential outputs in a second mode; and switches coupled to the first and second differential inputs to disconnect the test input signals from the second differential inputs during the first mode and to disable the receiver input signals by connecting first differential inputs to local core voltage while tri-stating the transmitter on the other side of the link during the second mode.

Abstract: A lighting device according to the present invention includes: a curvedly shaped base chassis having a reflection layer on its inner surface; an optical sheet facing the reflection layer to output illuminating light of the lighting device; a light source group, disposed between the base chassis and the optical sheet, including first light sources and second light sources emitting light in mutually opposite directions; a light source substrate mounted with the light source group, and a light distribution adjusting member, covering the optical sheet side of the light source group, to direct light from the light source group into predetermined directions. The directions of light emission from the light source group are in parallel with the light output surface of the optical sheet. The reflection layer is curved such that a portion thereof on each of the two direction sides is concave away from the optical sheet.

Abstract: A magnetically driven agitator which includes a member adapted to be mounted through a wall of a receptacle and which has a sleeve in which is housed a rotor which supports a first magnetic coupling structure. A propelling screw is disposed around the sleeve and supports a second magnetic coupling structure which cooperates with the first magnetic coupling structure in order to rotate the screw about an axis of rotation. The rotor is moveable parallel to the axis of rotation inside the sleeve between a first position where the first and second coupling structures are generally opposite to provide a maximum magnetic force therebetween to selected second positions where the magnetic force between the first and second coupling structures is varied such that the magnetic force may be reduced or substantially eliminated.

Abstract: A magnetically driven agitator for a mixture contained in a recipient which agitator is supported by a collar hermetically mounted in a wall of the recipient and which collar is provided with a blind sleeve inside which is housed a drive shaft provided with a first magnetic coupling. A propelling screw is disposed around the blind sleeve and is provided with a second magnetic coupling adapted to cooperative with the first magnetic coupling for driving the propelling screw about an axis of rotation. A third magnetic element carried by the propelling screw is disposed opposite a cell for detecting the movement of the third coupling element during rotation of the propelling screw about the axis of rotation.
