  • We constructed Seal type waterproofing with adhesive and swelling properties in the field of construction work as yet. But we have many problems of seal type waterproofing with adhesive and swelling properties for construction. Because it has high viscosity, so wokers are too adhered for the work. So, we developed and applied about the high temperature and spray equipments of piston type better than before. We able to be expect that cost reduction and increase construction ability by high temperature and spray equipments of piston type.

  • In this paper, propose an optimal design to improve the mechanical efficiency of gate valve made by forging method. In order to design the experiments using table of orthogonal array and optimization design is conducted as application of real response model to Taguchi method based approximation model using computer simulation. Also, from verification of the response model with optimized results was confirmed that usefulness and reliance of application Taguchi method to structural optimum design using finite element analysis and equation.

  • In this paper, we proposed a new method which does not need no load test for the characteristics analysis of linear induction motor. A new equivalent circuit of LIM is chosen and a method of determining its constants from results of the lock test is discussed. The calculated results were satisfactorily agreed with experimental results and conventional method.
