Title: Insect repellent and antioxidant comprising slightly volatile component contained in plant of genus alpinia
Inventor: TAIRA EIHIKO
IPC: C09K15/34
Filed: 2000-02-09
Abstract: PROBLEM TO BE SOLVED: To solve problems that it is necessary to find out a more inexpensive and safer method for separation in order to utilize a slightly volatile component because the cost required for extraction and expenditures necessary for safety control of organic solvents are high and the extraction is unsuitable for commercialization due to the extraction of the slightly volatile useful component from a plant of the genus Alpinia carried out by an organic solvent extracting method according to a conventional method though the time and cost required for the extraction can sufficiently be suppressed and the extraction is sufficiently performed out even without using an inclusion agent or a film-forming agent by utilizing the slightly volatile component in place of a volatile component contained in the plant of the genus Alpinia. SOLUTION: A slightly volatile component is separated from the plant of the genus Alpinia by using an ion exchange resin and the cost required for the extraction can thereby remarkably be reduced. Furthermore, expenditures required for the safety control can practically be eliminated because the organic solvents are not used. That is, the extraction from the plant of the genus Alpinia is carried out with hot water and the resultant hot water extract liquid is then treated with the ion exchange resin. The obtained permeate is concentrated and a precipitate obtained after the concentration is collected and used for an insect repellent and an antioxidant.

Title: Electric signal transmitting device
Inventor: SEKI HIDEO
IPC: H04L25/02
Filed: 2000-01-13
Abstract: PROBLEM TO BE SOLVED: To prevent an erroneous state caused by outer magnetic noises in electrical signal transmission. SOLUTION: A magnetic resistance element is connected to a second signal line in an electric signal transmission device. A field caused when a current is carried at the first signal line has an effect on the magnetic resistance element so that a change of current of the first signal line corresponds with a change of resistance in the magnetic resistance element of the second signal line, thereby carrying out the transmission of the electric signal in non-contacted state. In this case, the magnetic resistance element and the part of first signal line opposite to the magnetic resistance element are covered with a magnetic shielding member.  When any magnetic member for concentrating magnetic flux of generated field onto a part of the magnetic resistance caused by current carried at the first signal line is used, the magnetic member should be also covered with the magnetic shielding member.
