摘要:
A radio transmitter/receiver and an intermittent transmission/reception control method thereof, capable of reducing the reception startup time as well as suppressing reception power consumption. A radio transmitter/receiver used for ad hoc communication is provided with a dedicated standby reception unit (10) having a simple combination of an RF demodulator (6) and a SAW oscillator (7) only to detect a carrier. For a time period of several bits, the activation system of the radio transmitter/receiver intermittently receives activation selection signals transmitted using ASK (or OOK) modulation prior to a preamble signal, and makes an activation selection based on the pattern of presence and absence of the carriers of the signals. As a result, the reception startup time can be shortened, and less reception power is required.

摘要:
A cathode active material having an average discharge potential of 4.5 V or more with respect to Li metal is used, and as an electrolyte, a solvent with higher dielectric constant such as ethylene carbonate, and at least one of dimethyl carbonate and ethylmethyl carbonate are used in combination. A higher operating voltage can be realized while suppressing capacity reduction after cycles and reduction of reliability at a higher temperature.
