摘要： It is an object of the present invention to provide an optical recording medium that is suitable for recording information therein at a high velocity. An optical recording medium according to the present invention includes a recording layer formed of a phase change material and capable of recording data therein at a linear recording velocity equal to or higher than 10 m/sec, wherein Rtop satisfies the condition that it is larger than {11−(V/5)} and smaller than {22−(2V/5)}, where Rtop (%) is a reflectivity of the crystal phase change material forming the recording layer and V (m/sec) is a target linear recording velocity. According to the present invention, since modulation (MOD) of 50% or more can be ensured, it is possible to effectively suppress the degradation of jitter caused by recording data at a high linear recording velocity equal to or higher than 10 m/sec.

摘要： A metal-inorganic particle composite material is heated into a melt. Flux is thrown into the melt, and both the melt and the flux are brought into contact with each other sufficiently. The resulting melt is then left at rest so as to be separated into an upper layer containing inorganic particles a and a lower layer composed of metal. Subsequently the upper layer and the lower layer are recovered individually.

An image compression section compresses an image signal imaged by a video camera with an image compression ratio based on control information from a terminal control section. A speech compression section compresses a speech signal collected by a microphone with a speech compression ratio based on control information from the terminal control section. The terminal control section produces such control information based on keyboard input data from a keyboard, mouse input data from the mouse and common application operation information from a computer. A multiplexer multiplexes transmission compressed image data and transmission compressed speech data based on the control information outputted from the terminal control section and outputs transmission multiplexed data to a line interface.

摘要： A compressive encoder changes a search area in accordance with an attitude of a camera platform mounting a video camera on the platform. Responsive to a video signal from the video camera, the encoder executes compressive encoding together with motion compensation which uses motion vectors found out within the changed search area. Thus, the possibility that the motion vectors are founded out within the changed search area becomes high and effective compressive-encoding is achieved.
