Abstract: A transmitter/receiver (1) up-converts, using an LO signal as a local oscillation signal, an IF signal having a predetermined frequency band, thereby generating a transmission signal RFTX. Moreover, the transmitter/receiver (1) generates a (LO+IF)2 signal and a (LO?IF)2 signal based on the IF signal and the LO signal. Using the LO signal obtained by adding-up of the (LO+IF)2 signal and the (LO?IF)2 signal, a reception signal RFRX is down-converted. Thus, a local oscillation signal generation unit of a receiving unit is not necessary.

Abstract: The present invention provides a process for producing a molded foam article of a crystalline aromatic polyester resin. The process is characterized by heating the surface temperature of a mold for cavity-molding to the temperature within a range of from (td+35) to (Tg+57)°C. (Tg is a glass transition temperature of the crystalline aromatic polyester resin prepuffs), thereby to mold prepuffs, and cooling the surface of the mold to a temperature not lowered than Tg for at least 20 seconds.
