摘要： An image forming apparatus of the type including a plurality of process means for developing an electrostatic latent image provided on an image carrier to produce a visible image, transferring the visible image to a transfer material, and cleaning the image carrier after the image transfer. The image carrier and at least one image forming unit are individually removably mounted on a body of the apparatus. A first and a second sensor are provided for sensing, respectively, the end of the life of the image forming unit and that of the image carrier. Even when the end of the life of the image carrier is sensed, an indication for urging a person to replace the image forming unit being used is not produced if the life of the image forming unit has not expired, allowing the apparatus to be continuously used. It is not until the end of the life of the image forming unit is sensed next that an indication for urging a person to replace both of the image carrier and the image forming unit is produced.

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.
