    • A reversibly immortalized human pancreatic islet cell line containing an hTERT gene and an SV40T gene each interposed between a pair of LoxP sequences, characterized in that it is capable of producing insulin and enhancing expression of insulin after excising the hTERT gene and the SV40T gene, in particular, NAKT-13 (deposited with International Patent Organism Depository, National Institute of Advanced Industrial Science and Technology, address: AIST Tsukuba Central 6, 1-1, Higashi 1-Chome, Tsukuba-shi, Ibaraki-ken, 305-8566 Japan, deposited date: Sep. 4, 2003, accession number: FERM BP-08461) or a passage cell line thereof; a human pancreatic islet cell obtained by excising the hTERT gene and the SV40T gene from the reversibly immortalized human pancreatic islet cell line or passage cell line thereof; and use of these cells. By using the reversibly immortalized human pancreatic islet cell line of the invention insulin-producing cells can be easily and surely obtained in a number enough to meet the demand.

    • An electrical contact pin has a fixing part to be fitted into a through hole of a circuit board for fixing without using any solder. The fixing part has a substantially rectangular cross section. A pair of alternating recesses are provided on opposite sides of said rectangular section. A pair of corners closer to said recesses extend beyond said sides to form a pair of projected corners. A process for manufacturing such an electrical contact pin is characterized by the step of pressing a metal work having a substantially rectangular cross section to form said fixing part in a pair of metal dies. A pair of projections are provided on the bottoms of said dies to form said recesses. A pair of opposite sides of said dies are arranged so that there may be small spaces between said pair of sides and the opposite sides of said work before pressed. A part of said bottom of each die is made deeper than the rest of said bottom so as to form said projected corner when said work is squeezed.
    • 电接触销具有固定部分,以将其装配到电路板的通孔中,用于固定,而不使用任何焊料。 固定部分具有大致矩形的截面。 一对交替的凹槽设置在所述矩形部分的相对侧上。 靠近所述凹部的一对角部延伸超过所述侧面以形成一对突出的角。 用于制造这种电接触针的方法的特征在于:按压具有大致矩形横截面的金属制件以在一对金属模具中形成所述固定部分的步骤。 在所述模具的底部设置有一对凸起以形成所述凹部。 所述模具的一对相对侧被布置成使得在压制之前所述工件的所述一对侧面和相对侧之间可以具有小的空间。 每个模具的所述底部的一部分比所述底部的其余部分更深,以便当所述工件被挤压时形成所述突出的角部。
