    • The present invention relates to an automatic teaching method for a circuit board inspection system and comprises a data transform step of transforming mounter data into data file for teaching; a coordinate transform step of corresponding coordinates for data for teaching transformed through the data transform step transform step with inspection system coordinates; and a teaching step of programming contents to be inspected based on data for teaching such as part coordinates, part names, reference names and part angles that are formed through the data transform step and coordinate transform step. An automatic teaching method for a circuit board inspection system according to the present invention not only completes teaching operation within a short period of time, but also substantially reduces set up time for a new circuit substrate by enabling automatic teaching utilizing mounter data of parts mounted on a forgoing actual circuit substrate.
    • 本发明涉及一种用于电路板检测系统的自动教学方法,包括将安装器数据转换成用于教学的数据文件的数据变换步骤; 通过具有检查系统坐标的数据变换步骤变换步骤变换的用于教学的数据的对应坐标的坐标变换步骤; 以及基于通过数据变换步骤和坐标变换步骤形成的诸如部分坐标,部分名称,参考名称和部分角度的教学数据来编程要检查的内容的教学步骤。 根据本发明的电路板检查系统的自动教学方法不仅在短时间内完成教学操作,而且还通过使用自动教学来实现新的电路衬底的安装时间,从而利用安装在 一个实际的电路基板。

    • The present invention relates to a reverse transcriptase having improved thermostability, more precisely a mutant reverse transcriptase with improved thermostability by substitution of one or more amino acids selected from the group consisting of the 63rd glutamine (Q63), the 264th lysine (K264), the 295th lysine (K295), the 306th threonine (T306), the 346th glutamic acid (E346), the 408th proline (P408), the 438th histidine (H438), and the 454th asparagin (N454) of the amino acid sequence of M-MLV originated reverse transcriptase represented by SEQ. ID. NO: 1 with other amino acids. The mutant reverse transcriptase of the present invention demonstrates excellent thermostability, compared with the wild type reverse transcriptase. Therefore, it is advantageous to obtain the target cDNA with stable reverse transcription activity even in the presence of RNA that can form the stable secondary structure at a high temperature.
    • 本发明涉及具有改善的热稳定性的逆转录酶,更准确地说,具有通过取代选自第63位谷氨酰胺(Q63),第264位赖氨酸(K264), 第309位赖氨酸(K295),第306位苏氨酸(T306),第346位谷氨酸(E346),第408位脯氨酸(P408),第438位组氨酸(H438)和第454位天门冬酰胺(N454) MLV起源于SEQ ID NO: ID。 NO:1与其他氨基酸。 与野生型逆转录酶相比,本发明的突变型逆转录酶表现出优异的热稳定性。 因此,即使在能够在高温下形成稳定的二级结构的RNA的存在下,也可以获得具有稳定的逆转录活性的靶cDNA。
