摘要:
A residential facility control system transmits data as a radio signal between host and subsidiary apparatus. Transmitting and receiving devices of the host and subsidiary apparatus are reduced in power consumption. A transmitting circuit of the transmitting device of the transmitting and receiving apparatus is supplied with power from a transmitting circuit power source control in synchronization with a first timing signal from a first timer for a period of time which is necessary for transmission. A receiving circuit of the receiving device of the transmitting and receiving device is supplied with power from a receiving circuit power source control for a shorter period of time in synchronization with a second timing signal from a second timer which is synchronized with the first timing signal. When the receiving circuit receives a signal for the shorter power supply period of time, the receiving power source control maintains power supply to the receiving circuit for a period of time which is necessary to receive the signal. Synchronization between the first and second timing signals is achieved by initializing the second timer by way of timer synchronization device each time when the receiving device receives an effective signal or by regularly transmitting a forced synchronization signal to the receiving device from a forced synchronization signal generator provided in the transmitting device and by receiving the synchronization signal at the receiving device to initialize the second timer by way of the timer synchronization device.

A cooking device includes: first and second heating cooking units; a mode setting unit configured to set heating modes of the first and second heating cooking units; a receiving unit; a priority managing unit configured to store priorities which are given to the first heating cooking unit and the second heating cooking unit, respectively; and a power adjusting unit configured to adjust using power of a heating cooking unit to which a lower one of the priorities of the first heating cooking unit and the second heating cooking unit stored in the priority managing unit is given when the receiving unit receives a power adjustment request signal transmitted from a power controlling device. The priorities are different values for each heating mode.
摘要:
A cooking appliance performs cooking which is remotely controlled, based on information relating to the object to be heated, as the information is transmitted to the appliance's computer from a management's computer. The cooking appliance can also cook any part of food in the cooking chamber locally.

In a radio receiver apparatus of an orthogonal detection type, a voltage controlled first local oscillator generates a first local oscillation signal, and mixers mix an inputted reception signal with the first local oscillation signal and a 90.degree. shifted signal thereof, respectively, the mixed signals respectively being passed through first and second band-pass filters to obtain desired first intermediate frequency signals. Further, a second local oscillator generates a second local oscillation signal. Further mixers mixes the first intermediate frequency signals from the first and second band-pass filters with the second local oscillation signal and a 90.degree. shifted signal thereof, respectively. Then there is calculated either one of a sum of and a difference between the resulting mixed signals, the calculated signal being passed through a third band-pass filter to obtain a second intermediate frequency signal to be demodulated. Furthermore, an average frequency detector detects an average frequency of the second intermediate frequency signal for a predetermined time interval, and a frequency correction circuit controls the first local oscillation frequency of the first local oscillation signal based on the detected average frequency.

A washer-dryer is provided with a time shift function for performing timer presetting processing on the basis of a time shift computation result which indicates an operation start time suitable for operation. The washer-dryer includes: an input operation unit for allowing a user to perform operations for operating the washer-dryer; a display unit for displaying information relating to the operation of the washer-dryer; and an operation control unit for controlling the operation of the washer-dryer on the basis of the time shift computation result. When a start button on the input operation unit is operated by the user, the operation control unit automatically performs the timer presetting processing on the basis of the time shift computation result and also displays a timer preset time at the display unit.
