IPC: H03M7/40
Filed: 1992-09-25
Abstract: PURPOSE: To provide a Huffman decoder which can decode Huffman codes at a fixed speed by selecting the sequential bit string having the length corresponding to the maximum permissible length of Huffman codes from a data flow. CONSTITUTION: Sixteen subtractors 301-316 are each provided with a bit length related to a permissible Huffman code length. At the beginning of each composite cycle, data strings 331-346 having bit lengths which are shorter than the bit lengths of the subtractors by one are loaded into the subtractors 301-316. The subtractor 301 reads the most important bit and decides whether or not a sequential data bit string indicates a valid code. If the code is invalid, the shortest subtractor 301 inhibits all final outputs. Namely, the subtractor 301 sends a negative signal to a priority encoder 371. The other input to each subtractor is the minimum redundancy code having the same bit length as each subtractor has and the first redundancy code contains a code effective bit.  These redundancy codes 0-15 are stored in the appropriate bit-length register of each subtractor and the values of the codes are different among the subtractors.

Title: Microwave plasma processing method and apparatus
Inventor: OTSUBO TORU
IPC: H01L21/205
Filed: 1993-10-15
Abstract: PURPOSE:To provide a microwave plasma processing apparatus wherein plasma high in density and stability is generated, and ions impinging on a substrate are uniform in energy throughout the surface of the substrate. CONSTITUTION:A cavity resonator 1 is connected to a waveguide, whereby microwaves amplified in amplitude by resonance inside the cavity resonator 1 are radiated into a plasma generating chamber 6 through a slit to produce plasma of high density. That is, a microwave resonant section and a plasma generating section are so separated from each other as to prevent plasma from being generated in the microwave resonant section. By this setup, plasma can be stably generated without changing microwaves in a resonant state. Therefore, ions or radicals can be made to impinge on a work uniform in effect. In the result, a plasma treatment can be carried out with high speed ions optimal in energy. Furthermore, a uniform film can be formed at a high speed.
