摘要: In a selective calling circuit including a band-pass filter which may be constituted by an active filter, and a power source for energizing the filter, a control signal is generated which has a predetermined duration in accordance with the output of the band-pass filter at a point of time whereat the output of the band-pass filter reaches a predetermined level. In response to the control signal, there is established a state in which the center frequency of the band-pass filter can be changed, and the output of the power source is changed from a first level to a second level for a period of time substantially corresponding to the predetermined duration of the control signal. At the aforementioned first level, the band-pass filter may be energized, while at the second level, it may be deenergized.

摘要: A method of moulding foamed synthetic resin pellets of polyolefine in a mould, wherein the synthetic resin pellets are prepared with volumne of closed cells being more than 65 % of the total volume of the total cells and having an inorganic gas in the cells at a pressure higher than 1.18 atmospheres, then filled in a mould which is not completely gas tight, and then heated to expand and tightly adhere to each other. The pressure in the mould can be lower than ordinary pressure or at a vacuum and the pressure of the resin can be at a pressure higher than ordinary pressure. The moulded product may be removed from the mould after cooling or during cooling when the inner temperature of the product is between its melting point and a temperature 50.degree.C below the melting point. The obtained product may be stored at a temperature of 30.degree. to 70.degree.C below the melting point.
