Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To obtain 5-alkoxyamidolevulinic acids having high oil solubility and capable of generating free 5-aminolevulinic acid by hydrolysis and having high effect to an organism by converting 5-aminolevulinic acid useful as a herbicide, etc., into an amide derivative not containing a hydrochloric acid component. SOLUTION: This compound is 5-alkoxyamidolevulinic acid expressed by the formula (R is a 1-24C linear or branched alkyl or alkenyl) or its salt and is obtained by reacting, e.g. a chlorocarbonate of an alcohol corresponding to R with 5-aminolevulic acid hydrochloride in the presence of a base. For instance, 5-hexyloxyaminolevulinic acid is obtained by dissolving 5-aminolevulinic acid and sodium hydrogencarbonate into water and reacting with adding diethyl ether and hexyl chlorocarbonate. By the process, hardly isolable and instable free 5-aminolevulinic acids can be practicable.

Title: Optical waveguide type directional coupler and its manufacture
Inventor: EBISAWA FUMIHIRO
IPC: G02B6/13
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To adjust the branch ratio of the optical waveguide type directional coupler to a specific value by providing a trench right above a coupling part where two optical waveguides are close to each other and charging a filler in the trench. SOLUTION: The optical waveguide type directional coupler having two optical waveguides put closely on a silicon substrate 1 has the trench 6 which is deep enough to reach a core 3 or shallower than that right above the coupling part 5 where the two optical waveguides are close to each other, and a 1st filler 7 is charged in the trench. The coupling state of the directional coupler is changed by varying the refractive index of the filler 7 charged in the trench 6, and the branch ratio can be changed. The branch ratio of the directional coupler is determined by the waveguide interval, the distance by which they are parallel (coupling length), etc. The waveguide interval of several μm can not be made constant at the time of the manufacture.  This operation is therefore utilized to adjust deviation of the branch ratio, caused owing to variance in the waveguide interval, from its design value.

IPC: H03M7/40
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To execute encoding at a high compression rate by storing a symbol, a first symbol strong of expression with backspace reference, a delimiter and code words corresponding to them and converting the symbol string consisting of the inputted symbol into a symbol word string based on stored contents. SOLUTION: When it is determined that an inputted symbol can be received by normal expression with backspace reference in a code table by a collator in an encoder, the encoder outputs the encoded symbol which is expressed by a backspace reference variable number, after outputting the code corresponding to the inputted symbol and continuously outputs the encoded delimiter. At this time, when plural backspace reference variable numbers which are included in one symbol exist, the encoded delimiter is outputted at the interval of the respective variable numbers. In addition, matching with the symbol by normal expression is determined by a leading match longest group so as to be processed, and an encoding processing inside the backspace reference variable number is executed in terms of an recurrence. That is, the first encoding processing is interrupted temporarily, and a new one is executed.
