Title: Prefix-retrieving method using compressed retrieval table, and data structure
Inventor: LUNTEREN JAN VAN
IPC: G06F17/30
Filed: 2001-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a system for evaluating a fixed retrieve key for the unit of segment by retrieving all over a tree structure table without fail, for detecting output information which corresponds to the longest matching prefix. SOLUTION: Concerning at least one segment, only the selected bit of a retrieve key segment is used as an index for accessing a relational table preserving a test value to be compared with an individual retrieve key segment. The bit to be selected is determined by an index mask, while being reflected with the variance of valid test values (and valid retrieve key segment values) in a table entry. This enables table compression, for minimizing required storage conditions and retrieval time. A procedure is disclosed for generating the optimal index mask in response to the set of the valid test value.

Inventor: NISHI TEIZO
IPC: G02B5/30
Filed: 2001-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing a polarizing film by establishing a uniaxial stretching condition of a polyvinyl alcohol(PVA) film for obtaining excellent polarizing characteristics while neck-in is prevented from being generated. SOLUTION: When the PVA film is stretched uniaxially between rolls rotating at different circumferential speeds, the PVA film is subjected to hot stretching in the unwetted state at 60-120 deg. at first. The hot-stretched PVA film and the apparatus are kept in a state free from dew-condensation, the PVA film is preheated under the pressure of unsaturated steam and the PVA film is heated while the relative humidity is kept around 80-95% and then the PVA film is stretched immediately. The polarizing film of PVA having uniform physical properties can be obtained by using the hot stretching in the unwetted state together with the wet stretching as mentioned above. That is, the PVA film hot-stretched in the unwetted state is subjected to swelling treatment, dyeing and wet re-stretching so that the objective polarizing film is obtained.
