Abstract: A conduction control device comprises a first ferromagnetic region having relatively high coercivity, a second ferromagnetic region having relatively low coercivity and a junction region disposed between the first and second ferromagnetic regions. The device also comprises a gate for applying a field to the junction region so as to control charge carrier density within the junction region.

Abstract: The invention relates to an arrangement for projecting an image, which is made of pixels, onto a projection surface, including at least one light source whose intensity can be altered and which emits a light beam, also including a deflection device which deflects the light beam onto the projection surface, and a two-stage transformation lens system which is arranged between the deflection device and the projection surface. The invention also relates to optical systems for adjusting the angle of an incident light beam by means of a two-stage transformation lens.

Abstract: A magnetoresistance device includes an elongate channel formed of silicon. A conductor comprising titanium silicide is connected to the channel along one side of the channel and leads are connected to and spaced along the channel on the opposite side.

Abstract: A video projection system with at least one light source which can be controlled in intensity and generates at least one light bundle and with a deflecting device which deflects the light bundle sequentially to produce picture points of a video picture on a screen by picture and line scanning has two component groups, the first of which contains at least one light source and has a light output from which at least one light bundle exits, while the second component group contains the deflecting device and has a light input through which a light bundle can be imaged into the deflecting device. Further, a light transmission device is provided which enables the light output of the first component group to be optically connected with the light input of the second component group.

Abstract: The invention relates to a device for positioning an object relative to a carrier means, particularly for use in digital image conversion where an object has to be accurately positioned relative to the carrier means. This is achieved by tensioning said object by means of two strips and an elongated member to a mounting piece which moved by a displacement means positions said object. The positioning operation is observed through a measuring microscope.
