A process for producing fluoropolymer particles includes preparing a solution/dispersion containing fluoropolymer dissolved/dispersed in a first solvent such that the swelling of fluoropolymer by the first solvent is from 50 to 1,200%, and mixing the solution/dispersion with a second solvent such that fluoropolymer forms particles and the swelling of fluoropolymer by the mixture of the first and second solvents is from 0 to 100%. WC/WB is in the range of from 1 to 5, WB represents mass of the first solvent, WC/ represents mass of the second solvent, WC/WB represents a ratio of the mass of the second solvent to the mass of the first solvent. SBC/SB is at most 0.5. SBC represents the swelling by the mixture of the first and second solvents, SB represents the swelling by the first solvent, and SBC/SB represents a ratio of the swelling by the mixture to the swelling by the first solvent.

A radio communication system minimizes power consumption against noises. The system includes a first radio terminal (10A) with a first transmitter (40A) for transmitting a first data indicative of a specific event, and a second radio terminal (40A) with a battery (14B) and a receiver (20B). The first radio terminal (10A) includes a first bit interpolator (32A) which inserts a check bit pattern of “01010101” at a predetermined cycle into one frame of the first data. The second radio terminal (10B) has a second power controller (60B) which intermittently activates the second receiver (20B) at predetermined intervals in order to receive the bit-interpolated data from the first transmitter. A check bit detector (24B) is included in the second radio terminal (10B) to detect the check bit pattern from within the bit interpolated data and to issue a stop signal immediately upon occurrence of that the check bit pattern fails to appear at said predetermined cycle within a predetermined time frame shorter than one frame length of the first data. In response to the stop signal, the power controller of the second radio terminal terminates a current receiving operation.
