A tool for grinding and polishing diamond and a method for polishing diamond in which a single crystal diamond, a diamond thin film, a sintered diamond compact and the like can be polished at low temperatures without causing cracks, fractures or degradation in quality therein. The tool and method provide a polishing operation which is easy to accomplish, provides stable polishing quality, and provides decreased costs while maintaining stable grinder performance. The grinder is formed of a main component which is an intermetallic compound consisting of one kind or more of elements selected from the group of Al, Cr, Mn, Fe, Co, Ni, Cu, Ru, Rh, Pd, Os, Ir and Pt and one kind or more of elements selected from the group of Ti, V, Zr, Nb, Mo, Hf, Ta and W. The diamond polishing method includes pushing the above stated grinder against the diamond, and rotating or moving the grinder relative to the diamond while keeping the portion of the diamond subjected to polishing at room temperature. Alternatively, the portion of the diamond subjected to polishing can be heated to a temperature within the range 100-800&deg; C.

The methods of the present invention provide efficient mechanical milling or alloying of stock materials of titanium and aluminum in order to increase yield of the titanium stock and reduce cost in connection with the production of a titanium-aluminum-based alloy sinter. Sponge titanium, which has a particle size of 1 to 20 mm and which contains hydrogen at 3.5 mass % or more, is used as the titanium stock. The sponge titanium is ball-milled with an aluminum stock in an argon atmosphere to produce a hydrogen-containing titanium-aluminum-based alloy powder. Furthermore, this powder may be sintered, as required.

An enzymatic method for the preparation of a fructose-containing oligosaccharide, in which a .beta.-fructofuranosidase obtained by culturing Arthrobacter sp. K-1 (FERM BP-3192) as an enzyme is reacted on sucrose, raffinose or stachyose as the donor in the presence of an aldose or ketose as the receptor. The enzyme is characterized by:

In a method for preparing multiple glucosyl branched-cyclodextrins, a debranching enzyme is contacted to a mixture of maltose or a substance containing maltooligosaccharide such as maltose with a cyclodextrin to obtain a reaction product from which a branched-cyclodextrin is then separated; said branched-cyclodextrin is converted to glycosyl-cyclodextrin under the action of glucoamylase, which is thereafter mixed with maltose or a substance containing maltooligosaccharide such as maltose; and the resulting mixture is successively acted on by a debranching enzyme and glucoamylase.

The invention provides a method for pulverizing or granulating nuts or seeds which comprises mechanically grinding a mixture of nuts or seeds with a cyclodextrin. The invention also provides a stable particulate admixture of cyclodextrin containing nuts or seeds. The admixture is highly stable during storage and provides a versatile product for use in food processing.
