  • Publication number: 20130118649
    Abstract: A method for simultaneously annealing and applying a coating to a spring includes heating the spring up to a predetermined temperature that exceeds an upper limit of a permissible baking temperature range of the coating. The surface temperature of the spring then allowed to decrease to within the permissible baking temperature range of the coating, and then the coating is applied to a surface of the spring. The coating is then baked onto the surface of the spring while cooling the spring for at least a portion of the baking step. The heating and baking steps together achieve a predetermined low temperature annealing effect in the spring.

  • Publication number: 20130119045
    Abstract: A method of producing a spring which reduces time required for a heat treatment step of eliminating a machining strain generated by a forming step is provided. This production method is provided with a forming step (S10) of forming a spring steel material into a spring shape and a heat treatment step (S12) of eliminating a machining strain generated in the spring steel material by the forming step. The heat treatment step is executed by electrically heating the spring steel material by applying a current thereto. The heat treatment step has a first step of heating the spring steel material to a predetermined set temperature and a second step of keeping the spring steel material at the set temperature for a predetermined set time period subsequent to the first step. The set temperature is set to be higher than 430° C. but not higher than 500° C.

  • Publication number: 20120264143
    Abstract: A full-length cDNA corresponding to an EST (AA418955), which does not show any homology to other proteins in the database but has a weak homology to G-CSF, has been successfully isolated by synthesizing primers based on the EST sequence, and effecting PCR-cloning from a human fetal spleen library. Sequencing of the thus-isolated cDNA and analysis of its structure revealed that the cDNA has typical characteristics of a factor belonging to the IL-6/G-CSF/MGF family. It is also found out that the culture supernatant of said sequence-transfected CHO cells shows a proliferation supporting activity towards bone marrow cells in the coexistence of kit ligand.

  • Publication number: 20110293602
    Abstract: A novel human gene having a significant homology with a VEGF-C gene, a member of the VEGF family, has been isolated by the PCR method using primers designed based on the sequence of EST that is assumed to be homologous with the C-terminal region of the VEGF-C gene. Mouse and rat genes have been isolated based on the human gene isolated as above. A protein encoded by the above human gene has been isolated by introducing the gene into Escherichia coli and expressing it. The isolated protein and genes can be applied to, for example, gene therapy for the VEGF-D deficiency, wound healing, and promotion of collateral vessel formation. Furthermore, VEGF-D protein inhibitors can be used as a novel anticancer drug, etc.
