Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a fatty acid ester of astaxanthin by which the stable fatty acid ester good in absorption efficiency and usable for a food, a medicine, a cosmetic or the like is produced at high yield by using a lipase when carrying out an esterification reaction of the astaxanthin with the fatty acid. SOLUTION: Astaxanthin of the formula is esterified by a 14-22C linear or branched (un)saturated fatty acid by using one or more kinds of lipase such as the lipase derived from microorganisms belonging to the genus Candida or the genus Chromobacterium, the lipase derived from an animal pancreas, and the like to provide the objective fatty acid ester of the astaxanthin such as a fatty acid monoester of the astaxanthin or a fatty acid diester of the astaxanthin in the method for producing the fatty acid ester of the astaxanthin. The fatty acid ester of the astaxanthin is more stable than the free astaxanthin and provides high absorption efficiency in the intestinal canal. The fatty acid ester is useful for a food, a medicine, a cosmetic, a color-heightening agent of cultured fish or the like.

Filed: 1992-03-19
Abstract: PURPOSE:To fit an ID tag to a position where communication troubles are not caused and injury is hardly generated by arranging the ID tag having information to be read by means of the bar antenna of a fork lift vehicle on the back face of a beam viewing from a fork inserting port. CONSTITUTION:When the fork 4 of a fork lift vehicle is inserted into the opening part of a pallet 5, current flows in a bar antenna 6 by the function of a controller 16 so as to generate a magnetic field. Inducing by variation with time of the magnetic field, primary or secondary electromagnetic induction is generated, magnetic flux is passed through a front horizontal beam 19 so as to make the beam 19 to be a magnetic path, and hence induction electro motive force is generated in a bar antenna 14 for an ID tag. By this induction electro motive force, information for identifying respective pallets stored in an IC circuit 15 or the positions of the respective pallets are transmitted from the bar antenna 14 for the ID tag to the bar antenna 6. Thus, the signals can be delivered and received even if there is an iron beam between the bar antenna 6 and the ID tag 12.

Filed: 1995-04-19
Abstract: PURPOSE: To shorten accessing time until detection of the position of a target track by changing the number of track-jumping tracks according to reproduction position at the time of disk reproduction. CONSTITUTION: A pickup in a disk reproducing part 5 is moved to a specified position in the radial direction of a disk 6 and its position is set based on the control of a CPU 1. The difference between a reproduced track position based on address information read from the disk 6 and a track position recording target data is detected and when its positional difference is lower than a specified amount, the pickup is track-jumped only by the number of tracks set according to the positional difference. By changing the number of tracks track-jumped according to the reproduced position at this time, jumping is directly made to a position very close to the target track position and accessing time is thus shortened.
