Abstract: The present invention relates to methods for treating or controlling schizophrenia in a mammal using compounds having the Formula (I), wherein M1 and M2 are defined in the application.

Abstract: The subject of the present invention is a pneumatic brake booster comprising an envelope in which a skirt (2) slides in a sealed manner, a pneumatic piston (8) rigidly attached to the skirt, a three-way valve (20) actuated by a control rod (22) operated at a first end by a pedal, a plunger (32) mounted at a second longitudinal end which is the opposite end and slideably mounted in the body of the piston, the control rod and the plunger forming a brake control (33), characterized in that the said booster comprises means (68) of damping the relative and in particular oscillatory movement between the brake control (33) and the pneumatic piston (8).

Abstract: The invention relates to a method of manufacturing a field effect transistor comprising at the surface of a substrate of semi-insulating gallium arsenide W an active n-type active layer (102), on which is formed a gate electrode (G) of the Schottky type having at its lower part (15) the general form of a trapezoid, whose minor base is in contact with the active layer, then comprising on either side of the active layer a region of the n.sup.+ type (101 and 101') constituting the source and drain regions, of which the edges adjacent to the active layer are self-aligned with the edges of the major base of the trapezoid, and moreover comprising source (S) and drain (D) electrodes of the ohmic contact type formed at the surface of the regions of the n.sup.+ type.

Abstract: Fast filtering apparatus, particularly for biological liquids.It comprises in combination:an injection device equipped with a cylindrical reservoir, whose bottom is sealed by a porous pellet and whose top is sealed by a piston displaceable in translation in the cylindrical reservoir, the latter containing the liquid phase to be filtered;a filter support device comprising a cylindrical chamber, whose upper part is sealed by a porous pellet serving as a support for the actual filtering material;a device for bringing about the fast, temporary contact between the injection device and the filter support device;an electronic control assembly controlling each filtering operation, by simultaneously acting on the contacting device and on the mechanical means for the translation of the piston.
