IPC: B22D19/16
Filed: 1983-03-07
Abstract: PURPOSE:To obtain the defectless texture in the boundary region of a melt stuck part by coating a flux contg. a compd. having high affinity to the S contained in the melt of high-alloy cast iron charged previously into a casting mold on the surface to be melt stuck of said melt then post casting spheroidal graphite cast iron into the mold. CONSTITUTION:While a casting mold for a centrifugal casting method is rotated at a required number of revolutions, the melt of high Ni grain iron is charged therein and a shell layer 10 is solidified. The above-described flux (e.g.; the flux compounded with Na2CO3) is sprayed on the inside surface thereof. Pheroidal graphite cast iron which is the molten metal for a core layer 11 is post cast into the mold while the layer 10 in said state is still in a molten state. As a result, the abnormal structure of foreign matter remaining at the boundary surface with the high grain cast iron of the layer 10 is removed and the structure at the boundary surface of the high Ni grain cast iron of the layer 10 is thoroughly spheroidized by said removal coupled with the effect of a spheroidizing agent. The layer 10 and the layer 11 are thoroughly diffused during this time and the foreign matter is floated from the central part of the layer 11 to the upper riser and is throughly expelled together with the dross contained in the spherical graphite cast iron melt in the layer 11. The composite casting of the spheroidal graphite cast iron having the defectless boundary region is thus performed.

Abstract: PURPOSE:To make optimum clutter suppression possible by discriminating statistical distribution characteristics of a clutter amplitude to suppress clutter. CONSTITUTION:A Weibull distribution function setting circuit 3 determines a distribution function F(U) in accordance with a logarithmic conversion value U of a radar reception signal due to a logarithmic amplifying circuit 1 and an A/D converting circuit 2 and impresses it to a Weibull converting circuit 4. A converting circuit 42 operates and determines a value Y based on an equation I in accordance with a shape parameter K and a scale parameter delta set by a convertion parameter setting circuit 41 of the circuit 4. On a basis of this value Y, an amplitude characteristic discriminating circuit 5 calculates an inclination parameter, which is given by a formula II, in accordance with a value W defined by the integral value from the value Y to the infinite of the Weibull function and a value Z defined by lnY; and if a prescribed number of inclination parameters are equal to the parameter K, statistical distribution characteristics of the clutter amplitude is discriminated as a Weibull function distribution. Similarly, a log normal distribution is discriminated, and an optimum clutter suppression is performed in accordance with distribution characteristics.
