Abstract: The enclosure of the receiver device is divided into an antenna vicinity enclosure 1 and a demodulation unit enclosure 2, which are connected by a single transmission cable. By disposing the antenna vicinity enclosure 1 in the vicinity of the antenna, the high frequency feeder cable drawn from the antenna to the antenna vicinity enclosure 1 can be shortened. The effect of pulse noise and high frequency noise picked up by the conventional feeder cable can therefore be reduced. Furthermore, the length of the feeder cables in a quantity corresponding to the number of antennas is then reduced and the wiring space for the feeder cable can be reduced. The demodulation unit enclosure 2 is disposed spaced apart from the antenna, and the wiring space for the transmission cable can be greatly reduced in comparison with a case where a plurality of feeder cables are wired in the wiring space.

Abstract: A compiler section 15 converts a source program into an object program. A load module-executing section 12 outputs information on the portion placed in the wait state due to exclusive control during parallel processing of a source program 11, to an execution information-storing file section 13. A source program-reprogramming section 16 reprograms the source program, based on the information from the execution information-storing file section 13, by interchanging the portion under exclusive control with another interchangeable portion to prevent occurrence of the wait time due to the exclusive control.
