摘要:
A system that prevents unauthorized establishment of wireless bidirectional communication between a communication master and a communication terminal. The system includes a strength measurement signal transmission circuit that transmits a received signal strength measurement signal, which is used to measure received signal strength at the communication terminal, a number of times with different transmission strengths during a single wireless bidirectional communication session. A received signal strength measurement circuit measures the received signal strength of the received signal strength measurement signal whenever the received signal strength measurement signal is received by the communication terminal. A measurement result transmission circuit transmits received signal strength measurement results as a single response signal to the communication master from the communication terminal during the single communication session. A check circuit checks whether the current bidirectional communication is authorized based on the received signal strength measurement results from the communication terminal.

A short circuit protection circuit which readily recovers a relay drive circuit to an output operation state after a short circuit is cancelled while preventing the relay drive circuit from being damaged by a short circuit. The relay drive circuit outputs a drive current to a load in accordance with a first control signal. A short circuit detection circuit detects the occurrence of a short circuit at an output side of the relay drive circuit and suspends output operation of the relay drive circuit when a short circuit occurs. Further, the short circuit detection circuit intermittently transmits a recovery signal to the relay drive circuit in a certain time interval after a predetermined time elapses from when the short circuit occurs to recover the output operation of the relay drive circuit. The time interval is gradually increased whenever the recovery signal is transmitted.

Semiconductor devices are provided with high performance high-frequency circuits in which interference caused by inductors is reduced. In a semiconductor device including a modulator circuit to modulate a carrier wave by a base band signal to output an RF signal and a demodulator circuit to demodulate the RF signal by use of the carrier wave to gain the base band signal and a local oscillator to generate the carrier wave, inductors respectively having a closed loop wire are adopted. Interference caused by mutual inductance is reduced by the closed loop wire. For example, where inductors are adopted in the modulator circuit, a closed loop wire is disposed around the outer periphery of the inductors.

An electric vacuum cleaner includes an inlet port through which a suctioned air stream including dirt particles pass and a centrifugal separation member having a substantially circular space therein. The centrifugal separation member has a swirl portion to swirl the dust-laden suction air stream along an inner surface of the centrifugal separation member. By forming swirl passageway between the swirl portion and the inner surface of the centrifugal separation member, the high velocity swirling air stream can be made and consequently an efficiency of separating the dirt particles from the suction air and collecting the dirt particles can be improved.
