Title: Variable-length code decoding method and device
Inventor: NAN SHOGEN
IPC: H03M7/40
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To store variables in a memory and a latch and to rapidly decode the variable length codes by retrieving the node order of code words, encoded in a decoding mode by a specific operation and using the retrieved code order for the addresses of the decoded code words. SOLUTION: A packing part receives input of an encoded bit string to be encoded and including many variable length code words having the Huffman code tree structures as the bases and packs the bit string in the largest length of the variable length code word to output it to a border line extraction part. The border line extraction part detects the border lines of code words from the packed and outputted bit string by an expression I, for using the detected border lines for the memory addresses of code words. In such a constitution, the variables are simply stored in a memory and a latch with no change in hardware, despite the change in the Huffman code tree structure. Then the variable length codes can be rapidly decoded.

Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To convert substantially whole energy of a light beam formed in a light source to required linear polarization and to minimize the light loss by constituting so that all points on a mirror cross an optical path of one beam in a reflection beam. SOLUTION: In a reflection type polarizing element 42a, the position of a light convergent element 41a on an optical axis is set so that beams in circularly polarized components reflected by the reflection type polarizing element 42a are made incident on respective points on the reflection surface of the mirror 43. The reflection type polarizing element 42a is formed on a position that when the focal distance of the light convergent element 41a on the optical axis is defined (f), the distance from the focus F of the light convergent element 41a is nearly f/2 or below, further concretely, the distance from the focus F is nearly f/4.  Since the position and the size of the reflection type polarizing element 42a are decided in such a manner, the position of the mirror 43 is decided also to the position shifted from the focus F toward a light convergent member 41 by the distance of nearly 3f/4 on the axis parallel to the optical axis. Thus, all points on the mirror 43 cross the optical path of one beam in the reflection beam.
