IPC: A61P1/16
Filed: 1982-05-18
Abstract: PURPOSE:A cholagogue that contains, as a major active ingredient, a fraction soluble in an organic solvent, obtained by extraction of herb medicine in Zingiberaceae with an organic solvent, thus showing high durative effect. CONSTITUTION:A herb medicine in Zingiberaceae such as ginger or dried ginger is extracted with an organic solvent such as ethyl acetate or ethyl ether and the fraction soluble in the organic solvent is used as a major component. The fraction is obtained by cuttig the herb medicine into rough pieces, decocting with an organic solvent, and filtering. The decocting and filtration are repeated twice, then the extracts are combined, concentrated under reduced pressure at a temperature lower than 50 deg.C. The resultant fraction shows marked improved cholagogue effect compared with sodium deoxycholate as a reference. When the solvent for the extraction is relatively small in polarity such as ethyl acetate, it shows especially high cholagogue effect.

Title: Turbidity measuring circuit
Inventor: SASAKI TOSHIHIKO
IPC: G01N21/53
Filed: 1979-07-02
Abstract: PURPOSE:To realize the application of the photodetector in the optimum range and also ensure the working over a wide range of measurement without giving the range switching, by securing the continuous variation for the luminous intensity of the light source in accordance with the output of the photodetector. CONSTITUTION:With increase of the turbidity of sample 1, the illumination, i.e., the optical current of phototransistor Q2 decreases along with increase of voltage U4. As voltage U4 is applied to the inverse input of comparator 4, the output level of comparator 4 lowers down. Accordingly, the current which is supplied to LEDQ1 through Q3 increases, and thus the luminous intensity increases. When the output of comparator 4 lowers less than the set value, Zener diode D2 conducts with the base bias of Q3 held at the level of the output of comparator 4. And the current supplied to Q1 becomes constant regardless of the level of voltage U4. Comparator 5 generates the output corresponding to the difference of voltage U1 and U2 generated at resistance R4 and R6 each. And this output turns to the output signal OUT showing the turbidity of sample 1.

Abstract: PURPOSE:To reduce the lowering of Vth in charge transfer MOSFET and to obtain a boosting potential efficiently by impressing a source potential on a P-type well and by making it work as a substrate bias lowering the threshold value of the MOSFET. CONSTITUTION:Erasure of data is executed by giving a boosting potential Vpp from a boosting circuit 4 to a P-type well PW1 of a memory array 1 part and a substrate.
