  • Publication number: 20060153738
    Abstract: The present invention relates to a technique for analyzing the concentration of a specific component in a sample liquid, such as a method for analyzing a sample. The analyzing method includes a first detection step for irradiating light from a light source (50) onto a reaction system to detect a response from the reaction system (56) as a first detection result. The reaction system contains a sample liquid and a reagent. The method also includes a second detection step for irradiating light onto a reference board (54) to detect a response from the reference board as a second detection result. The response from the reference board under light irradiation is dependent on wavelength. The method further includes a calculation step for calculating the concentration of the specific component in the sample liquid based on the first and second detection results.

  • Publication number: 20060121759
    Abstract: In a connecter, the position at which a pointed part of a rocking terminal slidingly contacts an insertion and the position at which the pointed part of the rocking terminal contacts an upper surface of a terminal plate are substantially the same. Therefore, shavings generated by the contact of the insertion and the pointed part or foreign matters adhering to the insertion may adhere to the pointed part of the rocking terminal and be pinched between the pointed part and the terminal plate, whereby no contact is caused by inserting the insertion into the connector. Then, with regard to a connector having a switch part comprising a rocking terminal 51 swayed by inserting an insertion 53 into a main body of the connector and a receiving terminal 52 arranged to contact the rocking terminal, an pointed part 51a is formed on the rocking terminal, and the terminals contact electrically with each other by making the receiving terminal touch a side surface of the pointed part.

  • Patent number: 7050941
    Abstract: An online manual capable of efficiently identifying a trouble cause and not requiring trouble for updating. A service engineer (SE) connects an SE terminal to a service support system (1) and transmits a trouble event caused in a device to be repaired. In a judgment route data storage section (16), judgment materials for identifying a symptom cause are stored in the descending order of the goodness of fit. A data extraction section (20) extracts the judgment material in that order and represents it to the SE terminal. When the SE selects a judgment material matched with the state of the device to be repaired, the data extraction section (20) extracts a countermeasure action content corresponding to the judgment material from the countermeasure-action data storage section (11), an action data storage section (12), and a content storage section (13) and displays it on the SE terminal.

  • Publication number: 20060094098
    Abstract: A method of purifying a target protein from a solution, in which the target protein containing an electron transfer protein is dissolved, with the use of liquid chromatography. The liquid chromatography is performed by introducing the above-described protein solution into a tank filled with a packing agent, thus bonding the target protein to the packing agent, removing impurities, and then eluting the target protein from the packing agent with the use of an eluent containing a hydroxycholanoic acid salt. As an example of the above protein, glucose dehydrogenase containing a protein having an activity of dehydrogenating glucose is cited. The liquid chromatography is performed by combining hydrophobic chromatography with anion exchange chromatography.
