Title: Digit overflow processor of digital filter
Inventor: SANO SHIGENORI
IPC: H03H17/04
Filed: 1980-07-09
Abstract: PURPOSE:To prevent oscillating operation due to an overflow by performing overflow processing by outputting the maximum value of a dynamic range when input data is positive or the minimum value when negative. CONSTITUTION:According to the value of the output data of an adder 2 which adds the outputs of an adder 8 and a multiplier 1, a digit overflow circuit 12 controls the output data. When the absolute value of input data to the circuit 12 is >1, the input data is outputted as it is. When the absolute value of the input data to the circuit 12 is >=1 and <2, the circuit 12 outputs the maximum value of a dynamic range in response to the positive input or the minimum value in response to the negative one. Therefore, the circuit 12 prevents an overflow to prevent oscillations of a filter.

Title: Cooling method for rolling roll made of sintered hard alloy
Inventor: HAMAMATSU HISAYOSHI
IPC: B21B1/16
Filed: 1979-07-25
Abstract: PURPOSE:To extend the roll life, and to prevent the surface roughening, by directly pouring the cooling medium upon the roll part making no contact with the rolled material, without pouring the cooling medium directly upon the roll surface contacting with the rolled material. CONSTITUTION:The nozzle headers 4, 4', inject the cooling water 5 against the outer surface of the rolling rolls 2, 3. The baffle plate 7 is arranged so as to prevent the inner roll caliber of the rolling rolls 2, 3, from being directly shot by the cooling water 5. Hereby, the cooling water 5 is intercepted by the baffle plate 7 so that the cooling water never directly coolides with the surface of the roll caliber 6. Other parts of the rolling rolls 2, 3, than the roll caliber 6 are directly cooled by the cooling water 5, so that the heat to be received by the roll caliber as a result of contact with the rolled material is quickly transmitted to other parts than the roll caliber owing to the high thermal conduction characteristic of the sintered hard alloy to be the constituting material of the rolling roll; hereby, the cooling effect sufficient as a whole can be obtained.
