Title: Buffer solution for capillary electrophoresis
Inventor: YAMAGUCHI MASATO
IPC: G01N27/447
Filed: 1993-10-15
Abstract: PURPOSE:To provide buffer solution excellent in separability by which a low molecule organismic sample can be separated in a single base unit by containing glucomannan whose molecular weight is less than a specific value. CONSTITUTION:Buffer solution is obtained by containing glucomannan whose molecular weight is less than fifty thousand. In naturally obtainable konjak mannan, molecular weight normally falls within a range of about one million to two million, so that this molecular weight is necessary to be reduced by a chemical hydrolytic method or a decomposition method by oxygen. In the glucomannan having low molecular weight, when the concentration is set high, though a small mesh structure is formed, when the concentration is excessively high, injection into a capillary becomes difficult. In order to stabilize the mesh structure of the glucomannan, since to blend natural polysaccharide except the glucomannan such as agarlose is effective, the mesh structure of the glucomannan is reinforced by blending the natural polysaccharide, and long-term preservation or stability at repeatedly using time is secured.

Title: Receiving station of pneumatic conveyor
Inventor: FUREIZAA HENDAASON
IPC: B65G51/30
Filed: 1989-10-03
Abstract: PURPOSE: To automatically transfer a heavy article with a stopping distance shortened to the following conveying position by providing an arrestor means for arresting an article in a receiver; and by moving the receiver between an article-receiving position from a pneumatic tube and a discharging position. CONSTITUTION: The tube 13 of a housing 12 in a receiving station is connected to the tube 14 of a pneumatic tube conveyor. In an operational mode, a ram 19 is actuated at the expected timing in which an article conveyed in the tube 14 by means of air arrives at the receiving station, connecting a tube 16 to the tube 13. Thus the article is sent to the tube 16 through the tubes 14, 13. The carrying air is decelerated by externally escaping the carrying air from the bores 15 of the tubes 13, 16; the carrying air is terminated after striking a pat 18. Finally, the ram 19 moves the tube 16 to a dotted line position, connecting the tube 16 to a discharging tube 23. Thus the article downwardly slides on the discharging tube 23 with the aid of the gravitational force for discharge. The result stops a heavy article in a short distance, being automatically conveyed to the discharging tube.

Title: Liquid sample high-pressure differential scanning calorimeter device
Inventor: KAWAI SHOJI
IPC: G01K17/06
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To measure the thermal physical property of protein under high pressure condition at real time by providing a sample vessel and reference vessel having pressure tightness of at least a specified value, and providing a high-pressure connector for simultaneously and similarly pressurizing both the pressure vessels and a high- pressure pump to be connected thereto. SOLUTION: A sample vessel 2 and a reference vessel 3 have pressure tightness of at least 10 MPa, and the reason for simultaneously and similarly pressurizing both the pressure vessels is that it is necessary to simultaneously raise the pressure to the same pressure since both the sample and reference vessels must be placed in the same environment. A high-pressure connector 4 connects a high-pressure pump 5 to the vessel 2 and the vessel 3. The vessel 2 is connected to the vessel 3, whereby both of them can be laid in the same pressure, and are connected to the pump 5, whereby both vessels can be simultaneously pressurized. This device is provided with the connector 4 for pressurizing the vessel 2 and the vessel 3, the high-pressure pump 5 and a pressure gauge 6.  After the pressurization is performed to a prescribed pressure by this high-pressure pump 5, a general differential scanning calorie measurement is performed.
