Abstract: PURPOSE:To prepare a styrenic resin foam excellent in long-term heat insulating properties by using such a pressure and temp. condition that the melting amount of an evaporation type foaming agent is specific with respect to the addition amount thereof and the mean melting speed of the foaming agent per 1g of a styrenic resin is within a specific range. CONSTITUTION:When an evaporation type foaming agent prepared by mixing HFC-134a with an easy permeable foaming agent having a valve equal to or more than that of air in the gas permeability to a polystyrene membrane is added to perform extrusion foaming, in such a case that the addition amount of HFC-134a is set to (l/rho)X1.7X10<-5>-(1/rho)X5.3X10<-5>mol per 1g of a styrene resin, the melting amount of the evaporation type foaming agent calculated by integrating formula (a) is 95% or more of the addition amount thereof. When mean melting speed is 1.0X10<-7>-7.0X10<-7> mol./g.sec, an objective polystyrenic resin foam is obtained. When the melting amount is below 95% of the addition amount, the liberation phenomenon of the foaming agent is generated and appearance and physical properties lower. When the melting speed is 1.0X10<-7>mol/g.sec or less, a stagnation time is too long and productivity lowers. When the melting speed is 7.0X10<-7> mol/g.sec or more, an extrusion system becomes unstable.

Abstract: PURPOSE:To improve the deterioration of a reproduction picture due to the color run of a comb-shaped filter by recording a chrominance signal or insuring against passing through the comb-shaped filter included by a reproduction system when the vertical correlation of the chrominance signal is weaker than the prescribed value. CONSTITUTION:An Y signal (b) and a C signal (f) are separated from an input signal (a) by a comb-shaped filter COMB2. The input signal (a) and its 1H delay signal are passed through BPFs 25 and 24 to become signals (c) and (d) of 3.58mHz and transmitted to a compartor circuit 2. The amplitude or phase of the signal (c) is compared with that of the signal (d) by the comparator circuit 2, and a difference signal (e) in accordance with the vertical correlation is outputted. This control signal (e) is applied to a switch circuit 27. When the signal (e) is at a low level (strong vertical correlation), the output of the COMB2 is selected. When the signal (e) is at a high level (weak vertical correlation), the input signal (a) is selected. As a result, the color run of a chrominance signal output (g) from a BPF8 can be improved.
