Abstract: An electronic apparatus includes a communication interface, a memory, a microphone, a speaker, a touch screen display, and at least one processor. The electronic apparatus transmits voice input and identification information matched with the compatible information, to an external server in response to receiving a voice input for performing a task, to obtain state information of an executing application. The electronic apparatus stores the incompatible information matched with the identification information in the memory, receives action information, which is generated based on the voice input and the compatible information, and the compatible information from the external server, to obtain the incompatible information stored in the memory, using the identification information matched with the compatible information. The electronic apparatus performs the task based on the action information, and uses the obtained incompatible information when performing the task.

Abstract: A compressor including a hinge recess formed at a rolling piston and a hinge protrusion formed at a vane to be inserted into the hinge recess. A diameter of the hinge protrusion is greater than an interval between both ends of an opening of the hinge recess. A bearing surface, which comes in contact with an inner circumferential surface of the hinge recess, of an outer circumferential surface of the hinge protrusion, has a circumferential surface below 90° at both sides, respectively, based on a central line in a lengthwise direction of the vane. This structure may facilitate cutting and grinding of the bearing surface so as to produce machining costs, and also improve a machining degree and thus stabilize behaviors of the rolling piston and the vane so as to enhance compression efficiency.
