Abstract: A receiver includes: a broadcast reception unit configured to receive a broadcast signal; a keyword acquisition unit configured to acquire a search keyword based on metadata included in the broadcast signal; and a transmission unit configured to transmit the search keyword acquired by the keyword acquisition unit to a terminal device.

Abstract: The receiver (90) is provided with an application authentication unit (917) which uses a verification key to verify whether or not a signature of an application is valid and authenticates whether the acquired application is either an A-application or an ordinary application based on the validity of the signature; and a resource access controlling unit (918) performing a resource access control based on a resource access controlling table.

Abstract: When a defrosting requiring signal is outputted, the opening of a motor-operated expansion valve (5) is fully closed in a heating cycle so that refrigerant is recovered into a receiver (4). In addition, when the defrosting requiring signal is outputted, an indoor fan (6f) is deactivated so that heat is stored. Further, when the completion of the recovery of refrigerant is determined, defrosting operation is executed. The recovery of refrigerant is completed when an outdoor heat-exchange temperature Tc at the present time drops to or below a specified temperature, when the outdoor heat-exchange temperature Tc at the present time drops to or more than a specified difference from a reference outdoor heat-exchange temperature Tcl at the time before the motor-operated expansion valve (5) is fully closed, when an indoor heat-exchange temperature Te at the present time rises to or above a specified temperature, or when a set time passes.

Abstract: An air and liquid-tight container is capable of storing different substances in different compartments sealingly separated by a front gasket having two separate parts that are independently slidable. A rear gasket is connectable to a push rod so as to function as a plunger, the front gasket being slidable in response to sliding of the rear gasket, thereby enabling the substance in the rear compartment to be introduced into the front compartment through a bypass. The front and rear gaskets are encased in the tubular body at a compressibility C (%) of 2% to 10%, with the product of the compressibility and the contact area (mm.sup.2) of the gaskets with the inside wall of the tubular wall falling within the range of 150 to 400.
