Title: Speaker
Inventor: NAKAMURA TAKESHI
IPC: H04R1/40
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To obtain a clear low sound frequency level through the reproduction of only a low-frequency sound by providing two sounders, made of piezoelectric bodies placed to openings at both ends of a cylindrical main body and a film placed between two cylindrical covers with a bottom to cover the two sounders, so as to reproduce a low-sound frequency regardless of its small size. SOLUTION: At each of both end openings of a cylindrical main body 12 having a 1st opening 18, a 1st damper 16 clamps a sounder 16, a 2nd damper 24 fixes a film 26, and each cover 20 having a 2nd opening 22 is provided. The two sounders 16 are driven by right and left channel stereophonic signals respectively. Thus, a low-frequency sound without a phase difference of the right and left channel signals is radiated from the 1st opening 18 as a double- pressure resonance sound to obtain a sufficient low-frequency sound level regardless of its small size and a clear sound with unpleasant sound components suppressed therefrom is obtained from the 2nd opening 22, because the radiation of the sound wave is attenuated by the film.

Title: Method of enzymatically fractionating highly unsaturated fatty acid
Inventor: ROORENSU SANDOZU
IPC: C11C3/02
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To obtain a fraction contg. highly unsatd. fatty acids having a degree of unsaturation of 3 or higher by hydrolyzing an oil rich in highly unsatd. fatty acids with a nonspecific lipase, collecting the resultant fatty acid mixture, esterifying the mixture with a lipase of the genus Mucor in the presence of methanol, and collecting and purifying a nonesterified fraction.  
     SOLUTION: Black currant seed oil, borage oil, and evening primrose oil rich in γ-linolenic acid are used as starting oils. These oils are hydrolyzed with a nonspecific lipase of Candida cylindracea at room temp. at a neutral pH to give a fatty acid mixture, which is esterified with a lipase of the genus Mocor in a solvent contg. methanol. Since highly unsatd. fatty acids are not esterified in this esterification step, the mixture after the esterification is stirred together with an alkali (e.g. sodium carbonate) at 20-80°C until the mixture divides into an aq. phase and an org. phase. The aq. phase is separated, then is acidified with a hydrochloric acid soln., and is extracted with an org. solvent (e.g. hexane) to give highly unsatd. fatty acids.
