Abstract: A digital control device includes a first controller which generates a control reference signal of a first controlled variable of a controlled system, a first frequency converter which converts said control reference signal into pulses of a frequency proportional to a magnitude thereof, a second frequency converter which converts a measured value of a second controlled variable of said controlled system into pulses of a frequency proportional to a magnitude thereof, and a second controller which obtains a difference between the output pulses of said first frequency converter and the output pulses of said second frequency converter and which controls said second controlled variable by using said difference as a control reference value.

Abstract: The present invention is directed to a process for producing foamable polyolefin particles comprising adding a mixture of 3 to 15 parts by weight of a blowing agent and 0.5 to 5 parts by weight of a blowing aid to 100 parts by weight of polyolefin particles maintained in a fluid state. The addition of the mixture of blowing agent and blowing aid is conducted under substantially anhydrous conditions, which result in the blowing agent being present in the particles in a gas phase and not a liquid phase. Polyolefin particles comprise polyolefin resin with vinylaromatic resin chemically bonded thereto.
