摘要： Motion picture data is compression-encoded by a compression encoder with the frame rate changing according to the amount of accumulated data of the buffer, which can adequately change the number of pieces of frame image data to be compression-encoded per unit time, according to the change in the picture of the motion picture. In addition, tracing is done to trace extract image data in the frame image data by using a simple motion vector detected for the frame image data of the motion picture data, a higher layer motion vector detector detects a motion vector of the frame image data by using the simple motion vector in common, and a compression encoder extracts the extract image data based on the results of tracing and compression-encodes it by using the motion vector.

摘要： A high-density magnetic recording medium uses a nonmetallic substrate, while still providing high in-plane magnetic anisotropy and remanent coercivity. Such a medium can be formed by depositing a seed layer on a textured surface of the nonmetallic substrate in a gas mixture containing oxygen or nitrogen and an inert gas, while controlling the oxygen concentration or nitrogen concentration, and subsequently exposing the surface of the seed layer to oxygen or nitrogen.

摘要： A method and apparatus for encoding a picture advantageously employed for encoding a picture. A plurality of input picture data are stored, and the quantity of the information of the input picture data from the plural stored picture data is evaluated for detecting a scene change. A GOP of a preset unit length, made up of a picture formed by compression by intra-frame coding and a picture formed by compression by inter-frame predictive coding, is selected based upon a scene change detection output and the input picture data is encoded in a pre-set manner in accordance with the selected GOP. By detecting a scene change and selecting the intra-frame coding as a compression method responsive to scene change detection, the compression efficiency is raised at a scene change portion of the input picture data where the correlation between previous and succeeding pictures is lowered.

摘要： Excellent negative resistance characteristics are attained in a resonant bipolar transistor (RBT) while improving current gain. A first conduction type collector layers and the opposite conduction type base layer are sequentially formed on a semiconductor substrate. A quantum well structure in which a quantum level of electrons or holes is generated, and a contact layer of the same conduction type as the base layer are sequentially formed on a part of the base layer. An emitter layer of the same conduction type as the collector layer is formed directly on another part of the base. Since good negative resistance characteristics can be attained by utilizing the resonant tunneling effect of base majority carriers, and the quantum well structure causing carrier accumulation can be eliminated from the path of carriers flowing between the emitter and the collector, it is possible to reduce the recombination current at the emitter-base interface and in the quantum well structure, thereby improving current gain.
