IPC: E01F8/02
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To allow a soundproof wall panel to be radiated by sunlight efficiently and directly by forming the back face of the soundproof wall panel with a rugged face, and providing a cover layer of a photocatalyst on its outside face. SOLUTION: A sound absorbing material 3 is arranged in a casing having many sound absorbing openings 1 on the front face. Its back face section is formed with a rugged face, and a cover layer of a photocatalyst is provided on its outside face. When this soundproof wall panel is erected, fixed and supported between stanchions erected in the central separation zone of driveways to construct a soundproof wall structure, it absorbs and reduces the noises of automobiles running on the driveways on both sides of the central separation zone. The photocatalyst decomposes and reduces the nitrogen oxides and sulfur oxides discharged by automobiles in the range that it receives the direct projection of the sunlight. A self-cleaning capability is exerted on the surface of the soundproof wall panel by the high hydrophilic property of the photocatalyst.  The soundproof wall panel is radiated by the sunlight efficiently and directly to the utmost, and it can contribute to the maintenance and conservation of environment.

CONSTITUTION:The KANA to KANJI converter is provided with a word length obtaining means 7, a character sequence changing means 8, a reverse consulting word conversion dictionary file 10, and a reverse consultation retrieving means 9, the length of a word is checked from a word inputted to a KANA (Japanese syllabary) to KANJI (Chinese character) conversion buffer 5, and by utilizing the length of the word, the word in the KANA to KANJI conversion buffer 5 is rearranged from the ending of the word to the head of the word. The word corresponding to the rearranged word is retrieved from the words of the reverse consulting word conversion dictionary file 10 registered by being rearranged from the ending of the word to the head of the word for a reverse consultation retrieval, and whether it is a word brought to longest coincidence or not is decided. In the case of a usual word order, words in which characters of an a-line, a ka-line and a sa-line exist in the head of the word increase, but when the word order is rearranged in reverse, the whole is averaged, and therefore, the retrieval is averaged extending over all characters. In such a way, the time required for the retrieval can be shortened.
