Title: Immunopotentiator, its production and usage
Inventor: TOYOMASU TETSUO
IPC: C12P21/02
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To obtain an immunopotentiator capable of inducing the production of interleukin 12 and contributing to an indirect antitumor activity such as the strengthening of natural immunity and cell-mediated immunity by compounding a double strand RNA of an edible mushroom as an active ingredient. SOLUTION: This immunopotentiator contains a double strand RNA of an edible mushroom as an active ingredient. Further, to obtain the double stranded RNA, it is preferably isolated from an edible mushroom; for example, the RNA is contained mainly in a 80%-alcohol precipitated fraction obtained after an equal volume of ethyl alcohol is added to a hot water extract of the mushroom while stirring, and polysaccharides precipitated at 50%-alcohol are separated. Specifically, the extraction is carried out by adding a 1%-sodium dodecyl sulfate in an amount of 20 times and a tris-HCl buffer solution containing 100 mmol of sodium chloride to lyophilized powder of a mushroom such as Lentinus edodes.  From the extract, a fraction precipitated by a 50%-concentration ethanol is removed by centrifugal separation, then a fraction insoluble in an 80%-concentration ethanol is collected, proteins are removed from the fraction, impurities are decomposed and removed, and subsequently the objective RNA is isolated and purified by chromatography or the like.

Title: Working method for sharpening blunted tip
Inventor: TANIGUCHI NORIO
IPC: C23F4/00
Filed: 1979-03-27
Abstract: PURPOSE: To sharpen easily the tips of many diamond tools simultaneously, by ion- sputtering the blunted tips of diamond tools etc. in vacuum.  
     CONSTITUTION: When the tip of a hard tool such as diamond tool etc. is blunted, the blunted tip is ion sputtered from above with Ar ion beam of 1 k eV in vacuum not lower than 10 -2  Torr. The angle of incidence of the ion beam except at the top end is not smaller than 0°, and the degree of sputter-working is extended to 60°, as a result the working on the inclined plane advances quickly as shown by dotted lines, and the top is worked later. Hence, the conical tip of a diamond tool, blunted to about 2μm in radius of curvature at the top, is sputtered to a sharp shape 0.02μm in radius of curvature. This method permits to sharpen many tips of tools simultaneously without requiring skillfulness.
