Patent JP-H02290140-A (JP)
Title: Underwater motor
Inventor: YAMAMOTO SUMIO
IPC: H02K5/132
Filed: 1989-04-27
Abstract: PURPOSE:To improve erosion and corrosion resistance and to improve reliability by incorporating a core constituted of electromagnetic steel plates made of 0.4-2.5% Cr, less than 4.5% Si, at least either 0.1-2.5% Cu or Mo as principal elements of core materials, the remainder Fe and impurities. CONSTITUTION:Corrosion resistance promotes when raising the concentration of dissolved oxygen to 50ppb, and it increases with the increasement of the rate of content of Cr. The ratio of the increasement of corrosion resistance FR is such that corrosion resistance FR increases about 10 times with 1% increasement of Cr. A core loss remains unchanged when the rate of content of Cr has 0.1-2%, and when the rate of content of Cr exceeds 2.5%, it increases in correspondence with the rate of content of Cr. When the rate of content of Cr is close to 0.4%, erosion and corrosion can be prevented by adding Cu and Mo, however, the maximum of the rate of content of Cu and Mo is 2.5% in both metals.

IPC: B22D11/16
Filed: 1985-05-21
Abstract: PURPOSE:To eliminate the need for mounting of a dummy bar by maintaining a drum gap in a tight contact state, increasing the rotating speed of the drums at a specified acceleration simultaneously with pouring and controlling the drum gap so that the solidified shells are formed to the same thickness. CONSTITUTION:A continuous casting device for a thin sheet controls the rotation of a driving source 10 for the water-cooled casting drums 1, 1' by a program controller 14 and adjusts the gap between the drums 1, 1' by controlling an electric cylinder 15. The gap between the drums 1, 1' is maintained in the tight contact state in the starting stage of casting. The rotating speed of the drums is increased at the specified acceleration simultaneously with pouring and the gap of the drums 1, 1' is so controlled that the solidified shells are formed to the same thickness. The drum gap is thereafter expanded and the rotating speed is increased until the prescribed sheet thickness and the prescribed rotating speed are attained. The need for mounting the dummy bar in the starting stage of casting or the recasting stage after breakout is thus eliminated.
