摘要:
An alternating-current power line is wired in a building for supplying alternating-current electricity to an electric load. A bidirectional power converter converts bilaterally between alternating-current electricity and direct-current electricity. A power storage unit is connected to the alternating-current power line through the bidirectional power converter. The power storage unit is charged with electricity from the alternating-current power line and discharges direct-current electricity into the alternating-current power line. A charge-and-discharge unit charges a vehicular power accumulating device with alternating-current electricity supplied from the alternating-current power line through a connecting terminal and discharges electricity outputted as alternating-current electricity from the vehicle to the connecting terminal. A power converter converts alternating-current electricity outputted from the vehicle through the connecting terminal into direct-current electricity and discharges the converted direct-current electricity through the bidirectional power converter into the alternating-current power line.

A power supply system includes a solar power generator, a storage, a controller, a calculator calculating a predicted amount of electricity consumed and a predicted amount of electricity generated, a calculator calculating a shortage amount that is a difference between the predicted amount of electricity consumed and the predicted amount of electricity generated, and a device setting a predicted amount of electricity stored. In a specified time in which electricity cost is lower than in other times, the controller controls such that the storage is supplied with electricity supplied to a building until an amount of electricity stored reaches the predicted amount of electricity stored. In the other times when an amount of solar power generation is larger than an amount of electricity consumed by an electric load, the controller controls such that the storage stores a surplus of the solar electricity.

An air-conditioning apparatus for vehicle use which can obtain sufficient heater capacity even in a cold-climate region, can utilize an existing heater unit, can combine a combustion type heater with a simple assembly operation, and can utilize exhaust heat of a motor for travel use of an automobile for heating a passenger compartment. The air-conditioning apparatus includes a refrigeration cycle connecting a refrigerant compressor, a refrigerant/water heat exchanger, a first pressure-reducer, and an exterior heat exchanger in an annular configuration. Further, a hot-water cycle connects the refrigerant/water heat exchanger, a hot-water heater core, an exhaust-heat cooler, and a water pump in an annular configuration and connects a combustion type heater in parallel with the refrigerant/water heat exchanger. Accordingly, during heat-pump hot-water heating, hot water, with a temperature raised by refrigerant condensation by the refrigerant/water heat exchanger, circulates in the hot-water heater core so as to obtain a required heater capacity. During combustion heater hot-water heating, hot water, with a temperature raised by combustion fuel in the combustion type heater, circulates in the hot-water heater core so as to obtain sufficient heating capacity even in a cold-climate region.

摘要:
In a heat exchanger having a coaxial pipe, the coaxial pipe is formed by integrating an inner pipe, an outer pipe and connecting walls together by an extruding or a drawing forming process. A header of a first connecting member is connected to a removed portion formed by removing a part of the outer pipe at an end portion of the coaxial pipe. A second connecting member is welded to the inner pipe at a more longitudinal end side of the inner pipe than the header. Thus, the coaxial pipe can be bent like a coil for downsizing the heat exchanger without reducing the heat-exchanging ability of the heat exchanger, and the total cost of manufacturing the heat exchanger can be reduced.

A method of driving a liquid crystal recording device comprises applying a drive signal to liquid crystal micro shutters defined at the intersection of common electrodes that are normal to signal electrodes. The drive signal is a signal experienced by a microshutter as a result of the application of a selected signal to the common electrode and the application of a recording signal to the signal electrode. Both the selected and recording signals contain components of frequencies grater and less than a specified frequency which causes the dielectric anistotropy of the liquid crystal to disappear. A drive signal which opens or closes microshutters for a selected period of time includes a signal whose frequency is lower than said specified frequency, and superposed waveform obtained when the signal whose frequency is loser than the specified frequency is superposed upon a signal whose frequency is higher than the specified frequency. A driving waveform which reversely sets the microshutters open or closed for the selected period of time is formed of a signal including a frequency higher than the specified frequency and a zero frequency signal. As a consequence of the application of signals of this nature to the microshutters, the temperature characteristics of the liquid crystal microshutters are improved.
摘要:
An electric power supply system has a sub breaker arranged in a sub line electrically connected with a power line to intercept an electrical link between a main breaker and the sub line if a predetermined value of current flows through the sub line. A current detector is arranged in the sub line to detect a value of current supplied to an energy storing portion. A controller causes a battery of a vehicle to store electricity with an electric current equal to or lower than a current value that is calculated by subtracting the value of current detected by the current detector from the predetermined value of current set for the sub breaker.
