Title: Electric winding up machine
Inventor: MUKODA TAKAHISA
IPC: B66D5/30
Filed: 2001-12-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electric winding up machine having the minimum distance between hooks (the minimum distance between an upper hook and a lower hook), while ensuring the performance of excessively winding preventive device.  <P>SOLUTION: Winding-up/winding-down operation is conducted by operating a switch. At the time of excessively winding-up and winding-down, a chain guide is pressed up through a winding-up/winding-down limit spring. By the rolling angle action of a limit lever, a contact of a limit switch is opened, thereby stopping winding-up/winding-down operation. In this electric winding machine, the winding-up limit spring for absorbing the impact at a winding-up upper limit is disposed on an outer peripheral part of the chain guide so as to be compressed.  <P>COPYRIGHT: (C)2003,JPO

Title: Huffman encoding and decoding method
Inventor: MITCHELL JOAN L
IPC: H03M7/42
Filed: 2001-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a Huffman encoding and decoding method which can be realized in a short time, using reduced processing resources and hardware. SOLUTION: Huffman encoding performed from an especially packed data format can be simplified by using two different table formats depending on the code length. In this way, a Huffman table can be also reduced in size. In performing the Huffman decoding method, the performing time can be reduced, by testing for the length of valid Huffman codes in a compressed data stream and using an offset corresponding to testing criteria. Thus, a particular test result for forming direct index into Huffman table symbol values can be obtained, while reducing the size of a reference table used for such a purpose.
