Abstract: In a display apparatus, an acquisition unit acquires coordinate information associated with a fiducial marker installed in a specific area of a real space and a virtual object including advertisement information, an imaging unit images a real image and the fiducial marker, a self-position specifying unit specifies a self-position from a distance and an angle from the imaged fiducial marker, a state detecting unit detects a distance and an angle of view from the virtual point based on the self-position, a selection unit selects any virtual object existing within an angle of view from the self-position, and a display unit displays a main object of the virtual object existing within the angle of view from the self-position in such a manner that the main object is superimposed on a relative position on the real image and displays a main object and a sub object of the selected virtual object.

Abstract: A refrigerator of the present invention includes a refrigerating cycle including a compressor, a condenser, an expander and an evaporator and filled with a flammable refrigerant, a load detector detecting a change in load of the compressor, and a control device detecting a damage which is a cause for leak of the refrigerant from the refrigerating cycle, based on a detection output of the load detector.

Abstract: A refrigerator-freezer is described, in which refrigerant leakage from the refrigeration cycle can be safely detected. The refrigerator-freezer comprises: a refrigeration cycle formed by a compressor, a capillary, an evaporator and an accumulator connected in series, and filled with a flammable refrigerant; a cooling fan configured to blow the cold air cooled by the evaporator in the refrigerator-freezer; and a refrigerant leakage detection system configured to detect leakage of the flammable refrigerant, wherein the refrigerant leakage detection system is provided with a temperature sensor configured to measure the temperature of a refrigerant conduit of the evaporator and judges that the flammable refrigerant is leaking in the low pressure side of the refrigeration cycle when the temperature is detected by the temperature sensor with the compressor being halted is no lower than a predetermined temperature.

Abstract: A refrigerator of the present invention includes a refrigerating cycle including a compressor (24), a condenser (25), an expander (30, 31) and an evaporator (16, 20) and filled with a flammable refrigerant, a load detector (41) detecting a change in load of the compressor (25), and a control device (43) detecting a damage which is a cause for leak of the refrigerant from the refrigerating cycle, based on a detection output of the load detector (41).

Abstract: A refrigerator includes a mode-change chamber, having first and second dampers which may be selectively used as a freezer compartment, refrigeration compartment or chill compartment. When the freezer compartment mode is selected, the first damper permits the flow of cold air into the mode-change chamber to maintain the temperature in the mode-change chamber at a freezing temperature. When the refrigerating compartment mode is selected, the second damper permits the flow of cold air into the mode-change chamber to maintain the temperature in the mode-change chamber at the selected refrigeration temperature. When the chill compartment mode is selected, the control temperature of the second damper is forcibly expanded by a heater to maintain the temperature in the mode-change chamber at a chill temperature between the freezing and refrigeration temperatures.

Abstract: A control circuit for a refrigerator in which the compressor is operated in a pre-cool cycle prior to automatic defrost and in a rapid cooling mode. The control circuit defrosts immediately following rapid cooling when a defrost signal is produced during rapid cooling.
