Title: Method for preparing sample for analyzing amino acid and kit for analyzing sample
Inventor: HUSEK PETR
IPC: B01J20/283
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To rapidly, effectively, and reliably analyze an amino acid by retaining the free amino acid in a liquid sample at an ion-exchange resin and releasing the amino acid in an elution medium, adding a derivative reagent to an eluate for forming the derivative of the amino acid, and separating the amino acid derivative from an obtained mixture. SOLUTION: When a free amino acid contained in a liquid sample is to be analyzed, the retention of protein is avoided if it exists, and liquid is subjected to ion exchange to retain the free amino acid at the ion exchange resin. By treating the resin in an elution medium, the amino acid is released from the ion-exchange resin and then is contained in an eluate. The amino acid contained in the eluate is formed into a derivative by adding a derivative reagent to the eluate and the eluation medium also plays a role of the derivative reaction medium. The obtained amino acid derivative is separated by the chromatography analysis. An absorbent cartridge used for separating the amino acid is made of a pipet chip in the market.

IPC: F25B9/14
Filed: 2000-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a cryogenic refrigeration unit which is simple of structure and is capable of obtaining ultralow temperature. SOLUTION: A displacer is inserted into a cylinder, and an expansion chamber is demarcated at one end of the cylinder. A drive means reciprocates the displacer.

A gas supply system supplies refrigerating gas into the expansion chamber through the first gas passage, and recovers refrigerant gas from the expansion chamber. The supply and recovery of the refrigerant gas are performed synchronously with the reciprocation of the displacer. A refrigerant gas container is coupled with the expansion chamber through the second gas passage having flow resistance. A third gas passage leads to a refrigerant gas container.  A gas pressure reducing means reduces the pressure within the refrigerant container through the third gas passage.

Filed: 2000-03-13
Abstract: PROBLEM TO BE SOLVED: To compensate the temperature dependence of EDFA in a 1525 to 1565 wavelength range and to realize wavelength multiplexed transmission. SOLUTION: First and second long-period gratings having different grating periods are formed in an optical fiber in such a manner that the peak wavelength in the curve of the optical transmission loss characteristics in the first long-period grating side is formed in the shorter wavelength side than the transmission band as shown in Fig 1 (a) and that the peak wavelength in the curve of the optical transmittance loss characteristics in the second long-period grating side is formed in the longer wavelength side in the transmission band as shown in Fig 1 (b).  When the curves of the optical transmission loss characteristics are shifted depending on the temperature, the optical transmission loss in the short wavelength side of the transmission band is increased with the increase of the temperature by the loss deviation characteristics of the first long-period grating to compensate the large gain deflection characteristics of an optical amplifier, while the residual gain deviation characteristics in the long wavelength side in the transmission band are compensated by the loss deviation characteristics of the second long-period grating. Thus, the gain temperature characteristics in the transmission band of the optical amplifier are compensated.

Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To obtain an n-type diamond semiconductor with improved characteristics, without losing crystallinity of diamond by having neutrons irradiated on 30Si-containing diamond and causing P to contain in the diamond by a specific nucleus conversion reaction. SOLUTION: 30Si-containing diamond containing is synthesized, and the 30Si diamond is irradiated with neutrons, thus forming an n-type diamond semiconductor containing P in the diamond by the nuclear conversion reaction of Si(n, γ)31Si → 31P. The larger the amount of 30Si is, the more the nucleus conversion reaction occurs, thus reducing the amount of application of neutrons by that amount. Also, by increasing the concentration of 30Si, the amount of Si doping into the diamond is reduced. At the same time, the amount of Si remaining in diamond after the nuclear conversion of 31Si →31P can be reduced, thus obtaining diamond with satisfactory crystallinity.
