IPC: B22D11/10
Filed: 1985-06-12
Abstract: PURPOSE:To reduce the fall of the temp. of molten steel and to save the energy as well by sucking from the nozzle provided on the bottom part of a container the burnup exhaust gas inside a molten steel container and by returning into the container from the exhaust gas jet port provided in plural pieces on the upper cover. CONSTITUTION:The inner part of a tandish 1 is primarily heated by the combustion gas passed from a burner 3. In this case the forming exhaust gas is absorbed at 50-150mm H2O pressure by an exhaust gas circulating fan 8 and blown out from the exhaust gas jet port 4 provided between the burner 3 to perform the secondary heating. It is preferrable to perform so that the pressure at the drying and heating up time inside the tandish becomes about + or -1mm H2O. It had better to perform the oxygen enrichment to the degree of 30-40%. The biased heat inside the tandish is thus eliminated and the heat reserve is increased and the energy saving can be performed as well by the circulating use of the combustion exhaust gases.

Title: Crystalline elastic body
Inventor: NAKANISHI HIROAKI
IPC: F16F1/02
Filed: 1991-05-31
Abstract: PURPOSE:To strengthen the part of a stress concentration existing in a crystalline elastic body by making amorphous the boundary part between a fixed part and an elastic deformation part by ion implantation and by preventing occurrence of cleavage thereby substantially. CONSTITUTION:In a crystalline elastic body formed monolithically of a crystalline material, stress concentration occurs in deformation in the boundary part between a fixed part and an elastic deformation part. When this boundary part is made amorphous, a face easy to cleave, which exists in a crystal, is removed. In an accelerometer, a beam 32 is the elastic deformation part while a frame 30 and a mass body 31 are the fixed parts. When the accelerometer receives acceleration and the beam 32 is bent, the boundary parts 34a and 34b are subjected to large stress concentration. Therefore, ion implantation is applied to the parts 34a and 34b so as to destruct the crystal structure of the parts, and thereby the parts are made amorphous. In order to make the crystal amorphous from the surface to the inside without fail, it is desirable to execute the ion implantation by a variety of incident energies.
