Patent number: 5538578Abstract: A method of joining end portions of a weatherstrip consists of introducing the end portions to openings in a mold such that a seal portion of the weatherstrip is compressed substantially to the shape of a seal lip of the seal portion. The end portions are separated in the mold by a predetermined gap and a rubber material is injected into the gap for mutually bonding the end portions of the weatherstrip. Such a method of joining allows the weatherstrip to be installed on complexly shaped openings with no degradation of sealing characteristics over the perimeter covered by the weatherstrip. A molding apparatus for joining said end portions includes a clamping member for assuring correct positioning of a sealing edge of the weatherstrip.Type: GrantFiled: October 28, 1993Date of Patent: July 23, 1996Assignee: Kinugawa Rubber Ind.

Patent number: 5084383Abstract: Residual extracellular protease activities of a Bacillus subtilis strain can be further reduced by introducing a gene for the stimulation of extracellular protease levels into the genomic DNA of the strain.The resultant strain whose extracellular protease activities are further reduced is transformed with a recombinant plasmid for secretion of a desired protein and the desired protein can be efficiently produced and accumulated in the culture medium in a large amount. The accumulated desired protein can be easily recovered from the culture medium.For example, the accumulation level of human growth hormone secreted by a B. subtilis MT-430 strain carrying recombinant DNA phGH427 for the expression and secretion of human growth hormone can be increased five to tenfold as a result of the above treatment for reduction of the residual extracellular protease activities of the extracellular protease-activity-deficient strain.Type: GrantFiled: July 18, 1990Date of Patent: January 28, 1992Assignees: Agency of Industrial Science and Technology, Ministry of International Trade and IndustryInventors: Yoshio Furutani, Masaru Honjo, Akira Nakayama, Koichi Kawamura, Hiroaki Shimada, Izumi Mita, Akiko Akaoka

Patent number: 5015574Abstract: A expression-secretion vector is constructed by using a DNA sequence comprising a DNA fragment obtained by subjecting a DNA sequence consisting of a region involved in the expression of a gene coding for an extracellular enzyme of a bacterium of the genus Bacillus and a region involved in the secretion of the enzyme thus expressed to a deletion in the region involved in the secretion which can enhance the extracellular production of a protein dependent on the DNA fragment. By transforming a host bacterium with a recombinant DNA molecule formed by inserting a DNA fragment comprising a gene coding for a desired protein into the expression-secretion vector and then culturing the transformed host, the extracellular production of the desired protein in a large amount can be accomplished.Type: GrantFiled: November 20, 1986Date of Patent: May 14, 1991Assignees: Agency of Industrial Science and Technology, Extra-Ministerial Bureau of Ministry of International Trade and IndustryInventors: Yoshio Furutani, Akira Nakayama, Masaru Honjo, Hiroaki Shimada, Kouichi Kawamura, Izumi Mita, Akiko Akaoka
