摘要： There is provided an image encoding method in a facsimile apparatus or an image filing apparatus as an image communication apparatus. In this method, a color image signal which is expressed by a plurality of color component signals to be encoded is input, the input color image signal is converted into a bit stream signal, and the bit stream signal is encoded by prediction encoding. A parameter for the prediction encoding is changed in accordance with the color image signal to be encoded. The encoding operation is executed adaptively to the color image signal to be encoded. By virtue of bit stream converting the binary color signal, efficient encoding using the color correlation can be executed and an increase in data amount is prevented. By encoding the bit stream signal using a dynamic arithmetic code, a binary color image can be efficiently encoded.

摘要： A heat treatment jig with a silicon carbide coating for production of a semiconductor includes a base material and a silicon carbide film formed on the surface of the base material by a CVD method. The silicon carbide film is formed from a plurality of layers substantially parallel to the surface of the base material, and at least one of the layers is formed as a nucleus formation layer while the other layers are formed as ordinary crystal layers so that crystal growth between the ordinary crystal layers across the nucleus formation layer is discontinuous while crystal growth of the silicon carbide in the ordinary crystal layers are continuous in a direction of thickness of the ordinary crystal layers.
