Title: Production of carrier for immobilizing enzyme
Inventor: KOGA NAOKI
IPC: C12N11/14
Filed: 1990-11-15
Abstract: PURPOSE:To improve acid resistance, specific surface area and enzymic activity of a carrier for immobilizing an enzyme by granulating a clay mineral such as sepiolite or attapulgite, treating the resultant carrier granules with an acid, removing soluble components in the carrier and then burning the resultant carrier. CONSTITUTION:A clay mineral such as sepiolite or attapulgite is subjected to crushing and the resultant carrier particles are subjected to extruding granulation, tumbling granulation, etc., and granulated. The obtained carrier grains are then treated with an acid solution to remove soluble components and the prepared carrier grains are subsequently burned. The components soluble in the acid are removed from the interior of the carrier by treating the carrier grains with the acid solution. As a result, durability in the acid is improved. In addition to crushing and granulating, various granulating methods such as an extruding granulation method for adding water to a raw material, providing a clayey form, then extruding and forming the resultant clayey material and subsequently cutting the formed material or a tumbling granulation method for dispersing and granulating the raw material with a small amount of water in a mixer and granulating the prepared material can be utilized as a method for granulation. Furthermore, alumina, silica or clay minerals such as attapulgite or bentonite having the hydrophilic surface may be used as the raw material in addition to the sepiolite.

IPC: H03H9/64
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To widen a band, without narrowing the cross width of resonators and the intervals of the resonators by installing a first cross finger electrode with a period length L, which converts input voltage into a surface acoustic wave, a second cross finger electrode with a period length L, which converts it inversely, and a first reflector group and a second reflector group, which have the specified period lengths by leaving specified intervals on both outer sides of the cross finger electrodes. SOLUTION: A surface wave on a piezoelectric substrate 100 which is excited by the cross finger electrode 2 is reflected between the reflectors 4 and 5. Energy is confined and a standing wave (first vertical resonance) is generated. Partial energy leaks outside and is reflected between the reflectors 6 and 7. Then, the standing wave (second vertical resonance) is generated. First vertical resonance and second vertical resonance are mutually connected and the strength of connection and a frequency difference between vertical resonances change by the number of the reflectors 4 and 5. Since both the resonances have symmetric/asymmetric modes, four resonances in total are generated. Thus, the four resonances can be adjusted according to the appropriate frequency intervals by the number.

Title: Injection molding device and controlling method thereof
Inventor: ISOJIMA YOICHI
IPC: B29C45/76
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To realize the optimum charging amount irrespective of the size of a molding and of its material quality by a method wherein the charging amount of an injection screw is controlled by comparing the data of the position of the injection screw through the measurement of the amount of rebound of the injection screw occurring at the time when an injection completes with the data given at a setting part. SOLUTION: An injection screw starts the injection of a molding material at a point (b) and completes its injection at a point (a). Then, when the injection molding pressure is temporarily lowered, the charged amount of molding material, which is compressed in a molding cavity through injection, expands, resulting in retreating the injection screw by the distance B mm through the rebound of the screw. This rebound distance B mm is detected by a position sensor and inputted in a detecting part. The data inputted in the detecting part is compared in a comparing part with the range of the set values inputted in a setting part and processed so as to judge the excess and deficiency of the charged amount of molding material at a judging part and, at the same time, control an injecting pressure cylinder.
