摘要： A compound semiconductor structure in the form of a superlattice film with effectively graded average composition, comprising an alternating lamination of two kinds of layers of different composition to form pairs of layers, the ratio of the thickness of one layer to the thickness of the other in said pairs of layers being gradually varied in the direction of thickness throughout successive pairs, thereby the average composition being effectively graded throughout the pairs. In a hetero-junction field effect transistor, the layer of effectively graded composition is used between a semiconductor layer making low resistance contact with a current-supplying electrode and a semiconductor layer where a two dimensional channel is to be formed. In case of AlGaAs/GaAs system, the Al composition is varied. When the superlattice film is heat-treated, Al in the AlGaAs layer diffuses into the GaAs layer, yielding a film with actually smoothly graded Al mole fraction.

摘要： An optical system is disclosed for an endoscope having a generally tubular distal end in which an objective lens assembly and an image sensor in the form of a solid-state video camera are internally housed so that an image formed by the lens assembly is focussed upon the input or pickup surface of the video camera. The video camera is disposed along or in proximity to the center axis of the distal end of the endoscope and in some instances is oblique with respect to the center axis. The video camera may be positioned in this way due to the provision of a reflecting surface which is angularly disposed in opposing relationship with an input surface of the video camera, and deflection means disposed in front of the lens assembly and within the objective lens assembly, or between the lens assembly and the reflecting surface so that an image formed by the lens assembly can be focussed on the input surface of the video camera.
