Title: Hydrolysis of polysaccharide
Inventor: OKATSU YASUKAZU
IPC: C07D277/56
Filed: 1991-05-31
Abstract: PURPOSE:To industrially advantageously obtain hydrolyzed substances of a polysaccharide, e.g. chitosan which is deacetylated material of chitin in a mild condition by hydrolyzing the polysaccharide in the presence of a specified compound having a thiazolidinecarboxylic acid structure. CONSTITUTION:A monosaccharide such as L-cysteine or D-mannose is converted into a thiazolidinecarboxylic acid compound of formula I (n is 2-6) by a reaction in the presence of pyridine, etc., in water and acetic anhydride is added thereto for acetylation. The resultant acetylated compound is reacted with a secondary amine such as dodecylamine and the obtained amide compound is treated with sodium methoxide for deacylation. The resultant compound represented by formula II (R1 and R2 are 8-30C alkyl; R3 is H or 1-8C acyl) is subsequently oxidized to obtain a compound represented by formula III (X is O or H2). In the presence of the synthesized compound and a phospholipid, a polysaccharide (e.g. chitin) is hydrolyzed to obtain hydrolyzed substances (e.g. chitosan) of the polysaccharide in a mild condition.

Title: Dc-dc converter
Inventor: HIROKAWA MASAHIKO
IPC: H02M3/28
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To reduce the size of a DC-DC converter and improve the efficiency of the converter, by connecting an output rectifier filter circuit to the secondary winding of a transformer, and constituting a constant-current load circuit against a circuit connected to the primary side of the transformer. SOLUTION: Desired DC output power is obtained from a DC-DC converter by making a sine wave electric current to flow to a resonance circuit 3 by periodically switching a DC power source 6 with switching elements 1 and 2, and transmitting the current to the secondary side of a transformer 4 from the primary side of the transformer 4, and then, rectifying and filtering the current by means of an output rectifier and filter circuit 5. The circuit 5 is constituted in a choke input rectifier and filter circuit constituting a constant- current load circuit against a circuit connected to the primary side of the transformer 4. Accordingly, the ripple current flowing to a filter capacitor 54 is made smaller by the action of an output choke coil 53. Therefore, the loss of the capacitor 54 of the circuit 5 caused by the ripple current becomes smaller.

Abstract: PURPOSE: To form a three-dimensionally patterned and crack-free coat by the procedure in which a specific under coat is applied on a base material with an uneven pattern, the paint layer on convexity is removed while the under coat is not hardened, and the same paint is again coated on the whole surface of the base material.  
     CONSTITUTION: The desired uneven pattern 2 is formed on the hard base material 1 such as color iron plate, etc., and then the under coat paint 6 mixed with a pigment and vehicle of a hue and lightness different from those of the base material is coated on the whole surface of the base material uniformly. Then, while the paint is not hardened, the paint layer 6a adhered to the convexity 4 and the corner 5 is removed by wiping, and then the same paint is again coated on the whole surface. Thus, a coat which is excellent in contrast due to different hue and lightness, has a three-dimensional feeling, and free of cracks in the corner portion can be obtained after hardening.
