  • Patent number: 10491732
    Abstract: A transmitter modulates an input voice signal to transmit an RF signal. A receiver demodulates a received RF signal to output an output voice signal. A voice level comparator compares a level of an input voice signal obtained by collecting a voice by a microphone with a VOX sensitivity level. A transmission determination unit instructs the transmitter to transmit the input voice signal, when the level of the input voice signal is equal to or greater than the VOX sensitivity level, based on a comparison result by the voice level comparator. A VOX sensitivity level calculator calculates the VOX sensitivity level in a predetermined period until just before the receiver completes outputting the output voice signal, based on an ambient sound collected by the microphone.

  • Patent number: 10418958

A transmission determination unit instructs a transmitter to transmit the voice signal, when the level of the voice signal is equal to or greater than the VOX level, based on a comparison result by the voice level comparator. A timer starts to measure an elapsed time from a point of time when a switch is operated. A VOX level selector seta a first VOX level as the VOX level when the elapsed time measured by the timer exceeds a reference elapsed time, and sets a second VOX level which is smaller than the first VOX level as the VOX level when the elapsed time measured by the timer stays within the reference elapsed time.

  • Patent number: 10164680
    Abstract: A radio communication device is provided with a VOX function. A reception completion state determination unit determines whether or not a reception unit is in a state of completing reception. A timer starts to measure a predetermined time when the reception completion state determination unit determines that the reception unit is in the state of completing the reception. A VOX level selection unit sets a VOX level at which the VOX function determines that transmission is made to a first VOX level after the timer finishes measuring the predetermined time, and sets the VOX level to a second VOX level smaller than the first VOX level while the timer is measuring the predetermined time.

  • Patent number: 10032582
    Abstract: A pair of fixed arc electrodes are arranged facing each other within a sealed container that is filled with arc-extinguishing gas 1. There are provided: a compression puffer chamber for accumulating pressurized gas that is obtained by elevating the pressure of the arc-extinguishing gas; and an insulated nozzle that directs the pressurized gas towards the arc discharge from the compression puffer chamber. A buffer chamber is provided, in which hot exhaust gas generated by the heat of the arc discharge is temporarily accumulated. A pressurized gas through-flow space is provided, communicating with the compression puffer chamber. In the pressurized gas through-flow space, an opening/closing section prevents inflow of hot exhaust gas by assuming a closed condition during the earlier half of the current interruption period, and in the latter half of the current interruption period the opening/closing section 41 is opened to allow flow of pressurized gas.

  • Patent number: 9997314
    Abstract: The gas circuit breaker includes a sealed container filled with an arc-extinguishing gas, a pair of fixed arc electrodes arranged in the sealed container to be opposite to each other, a trigger electrode movably arranged between the fixed arc electrodes and generating an arc discharge according to movement, a pressurization chamber pressuring and increasing a pressure of the arc-extinguishing gas with pressurization means, and a pressure accumulation chamber in communication with the pressurization chamber and accumulating the pressurized arc-extinguishing gas. The trigger electrode switches the pressure accumulation chamber into a closed state or an open state. The pressure accumulation chamber is switched to the closed state in a first half of breaking of the electric current, and the pressure accumulation chamber is switched to the open state in a latter half of breaking of the electric current. The arc-extinguishing gas in the pressure accumulation chamber is guided to the arc discharge.

  • Publication number: 20170117007
    Abstract: An inputter inputs a sound signal. A delayer delays the input sound signal. An acceptor accepts a command to transmit the sound signal. A transmitter transmits the sound signal delayed in the delayer when a level of the sound signal delayed in the delayer is larger than or equal to a threshold value when the acceptor accepts the command. On the other hand, the transmitter transmits the sound signal input from the inputter when the level of the sound signal delayed in the delayer is smaller than the threshold value.
