    • 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.

    • A power saving wireless fire alarm system has a master station and a plurality of battery-powered fire detecting terminals linked for wireless communication with each other. Upon detection of a fire occurrence at one of the fire detecting terminals, the fire detecting terminal transmit a fire detection message to a master station which in turn transmit a wake-up message to the other fire detecting terminals and thereafter a fire information message which starts a multiple synchronous communication between the master station and the fire detecting terminals. Each fire detecting terminal has a power controller which selects an intermittent reception mode of activating its own receiver only intermittently until receiving the wake-up message or information indicative of the fire occurrence, and select a constant operation mode thereafter to make the fire detecting terminals be ready for the multiple synchronous communication commenced by the fire information message from the master station.

    • An air intake passage system includes an external air intake port provided in a rear portion of a top cover and a passageway section projecting upwardly from the engine cover for directing taken-in external air to the engine. The top cover is provided over the engine cover with a gap therebetween such that the taken-in external air is allowed to flow into the passageway section and a water discharge section is provided between the engine cover and the top cover. Water, having entered together with external air, flows along the upper surface of the engine cover, bypasses the passageway section and is then discharged via the water discharge section.
