IPC: C04B37/00
Filed: 1989-12-28
Abstract: PURPOSE:To rapidly increase a contact area by plastic deformation and to lessen the influence of the surface roughness of joint surfaces as well as to allow rapid joining with a small pressurizing force by joining mullite ceramics by diffusion to each other under specific joining conditions. CONSTITUTION:The mullite ceramics are joined to each other by diffusion under the joining conditions specified to 1000 to 1700 deg.C joining temp., <=3mu crystal grain size, <=10<-3>/sec speed change rate and <=15kg/mm<2> deformation stress. Since the contact area increases rapidly according to the above-mentioned method, the faster joining than the conventional diffusion joining is possible and the joining is less influenced by the surface roughness of the joint surfaces. In addition, the ceramics are easily deformed by the low pressure and, therefore, the smaller pressurizing force is necessitated. The easy formation of the product consisting of the ceramics to a larger size or intricate shape is possible and the application range thereof is largely expanded.

Title: Alkaline battery
Inventor: TSUZUKI SHUSUKE
IPC: H01M6/08
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of heavy load discharging performance and the generation of internal short-circuit at the time of special discharge by using nonwoven fabric with the double-structure, which has a different density between a surface layer and a back layer thereof, as a separator. SOLUTION: A separator is formed of a nonwoven fabric formed of two layers (a surface layer and a back layer), and density of the surface layer is set at 0.30-0.35g/cm<3> , and density of the back layer is set at 0.20-0.23g/cm<3> . The back layer at a low density holds a large quantity of electrolyte at 77mg in relation to manganese dioxide at 1g. Consequently, malfunction that the heavy load discharging performance is lowered by a shortage of the electrolyte is not generated. Since the surface layer of the separator is formed at a high density, malfunction that the product on the negative electrode side passes through the separator and arrives at the positive electrode side so as to generate abnormality of discharge due to the generation of internal short-circuit at the time of special discharge is prevented.  Furthermore, since the separator is formed of single material of nonwoven fabric, generation of winding displacement can be avoided at the time of winding the separator into a cylindrical shape.
