Abstract: A scroll compressor may include a rotational shaft, the rotational shaft including a first frame support having an inner circumferential surface, into which a boss of a first scroll is inserted, and an outer circumferential surface that forms an outer surface of the rotational shaft; and at least one guide hole that extends from the inner circumferential surface to the outer circumferential surface.

Abstract: The present disclosure relates to an electronic device capable of performing complex biometric authentication, and the electronic device may include a plurality of biometric sensors configured to sense different biometric information, a security module configured to calculate a matching score for each of the different biometric information through a comparison between the different biometric information and previously registered user information, and calculate fake probability information for each of the different biometric information in consideration of a fake factor of the different biometric information, and perform user authentication using the matching score and the fake probability information calculated for each of the different biometric information, and a controller configured to control the electronic device based on a user authentication result performed by the security module.

Abstract: A scroll compressor is provided that may include a casing; a drive motor; a fixed scroll that forms a compression space by being coupled to the orbiting scroll; and a discharge cover provided at an inner space of the casing, the discharge cover having a space that communicates with the compression space and separated from the inner space of the casing, and having one or more discharge hole on a side surface thereof, the one or more discharge hole providing communication between an inside and an outside of the space. With such a configuration, vibration noise of the scroll compressor may be more reduced in comparison with a case in which an oil separator is provided outside of the casing. Further, as an area of the one or more discharge hole and a volume of the space are optimized, efficiency of the scroll compressor may be enhanced.

Abstract: A bush bearing and a scroll compressor including a bush bearing are provided. A boss of an orbiting scroll may be inserted into and coupled to a boss coupling groove of a rotational shaft, and thus, an outer circumferential surface of a bush bearing may wholly contact an inner circumferential surface of the boss coupling groove, thereby decreasing wear of the bush bearing. Further, friction loss in the bush bearing may be reduced, and thus, compression efficiency and reliability may be enhanced, noise may be reduced, and material costs may be reduced. Furthermore, despite that the bush bearing is formed in a ring shape and press-fitted to the boss, as the bush bearing may be formed of a plastic material having an ether ketone bonding in consideration of a thermal expansion rate, an elongation, and a press-fit range, the bush bearing may be effectively prevented from being detached from the boss, thereby enhancing a reliability of a compressor.
