Title: Production of beet saponin
Inventor: ENDO AKIRA
IPC: C09K23/56
Filed: 1990-08-24
Abstract: PURPOSE:To obtain the subject high-purity saponin excellent in workability and useful not only for foods but for cosmetics in high yield by removing high- molecular components by ultrafiltration and then recovering the objective saponin by centrifugation. CONSTITUTION:Crushed beet materials are extracted using water or an aqueous alkaline solution and the resultant extract is subjected to ultrafiltration to remove high-molecular components. The pH thereof is lowered using a mineral acid until flocks of beet saponin are formed and the resultant flocks are recovered by the centrifugal separation, thus obtaining the objective saponin. In addition, the recovered saponin is preferably dissolved in remarkably weak alkali solution and the obtained solution is passed through a synthetic adsorption resin to adsorb beet saponin onto the above-mentioned resin. The adsorbed saponin is subsequently eluted using a solvent.

Title: Thin-film magnetic head
Inventor: ARAI NOBUO
IPC: G11B5/31
Filed: 1988-09-07
Abstract: PURPOSE:To obtain the title head with little induced noise which is suitable for the high-density recording of a VTR, etc., in a mounted state by crossing a wiring pattern on a terminal board at least once. CONSTITUTION:A wiring pattern 8 crosses at least once on a terminal board 5 and the sum of the effective areas of an oblique line part 7 surrounded by the wiring pattern 8 and a coil 3 incorporating a magnetic core 2 to the induced noise by an extraneous wave is nearly equal to the effective area of the other oblique line part 9 to the induced noise by the extraneous wave. The polarity of the induced noise by the extraneous wave generated in the oblique line part 7 surrounded by the coil 3 incorporating the magnetic core 2 on a thin-film magnetic head chip and the oblique line part 7 surrounded by the wiring pattern 8 is reverse to that of the induced noise generated in the other oblique line part 9 surrounded by the wiring pattern 8. Consequently, they cancel each other and the interference of the extraneous wave can be completely canceled. Thus, the one with little induced noise which is suitable for the high-density magnetic recording of the VTR, etc., in the mounted state can be obtained.

Title: Electron source for picture image display
Inventor: KAWACHI YOSHIKAZU
IPC: H01J31/12
Filed: 1982-12-17
Abstract: PURPOSE:To reduce power consumption of hot-cathode without sacrifice of brightness of picture image, by arranging a linear hot-cathode at intermediate position against two through-holes of electron beam take-out electrode while regulating the potential to be applied on a rear face electrode to take out each of two electron beams from hot-cathode through said through-holes. CONSTITUTION:Electrons emitted from a linear hot-cathode 22 is taken out as two electron beams through through-holes 28, 28' in an electrode take-out electrode 23 shifted from the hot-cathode 22 by regulating potential on the rear face electrode 21. In other word, in a curve showing electron density distribution on said electrode 23 when varying the potential on the electrode 21, two through- holes 28, 28' are arranged at the positions corresponding to two maximum levels. Consequently both maximum levels of electron density distribution to be emitted from single hot-cathode 22 can be used simultaneously to take out two electron beams from single hot-cathode 22. Since the maximum level is high, electron beam density for each beam will never deteriorate to reduce power consumption.

IPC: H02M1/14
Filed: 1988-09-06
Abstract: PURPOSE:To prevent a noise generated in a power circuit from flowing out to the outside of an apparatus by starting and stopping all power sources in said apparatus simultaneously, by stopping all power circuit at the time of any trouble of a power circuit for contriving the safety of said apparatus, and by using isolate elements. CONSTITUTION:When a switch SW is disconnected or a contact ARL operates, a relay K1 becomes inoperative, a supply voltage is not applied to a control terminal G0, and a relay K2 also becomes inoperative. Therefore, a contact K2 opens and the transistor Q1 of a starting circuit 3 does not operate, a relay K3 becomes inoperative, and the operation of an auxiliary power circuit 8 stops. Accordingly, power is not given to a control circuit 7, which becomes a transistor Q2, and a power circuit 2 stops its operation. In said relays K1, K2, driving and contact parts are electrically separated from each other so that a noise in the power circuit 2 is not transmitted to the input power supply side and the effect of a filter 1 is displayed. Thus, said relays K1, K2 functions as isolate elements separating the power supply V side and the power circuit 2 side with the filter 1 in between.
