Abstract: A synthetic resin bearing and a scroll compressor using the same are provided. In the synthetic resin bearing as a journal bearing fixed to an orbiting scroll or a main frame and relatively rotated with respect to a rotational shaft in a scroll compressor, the journal bearing is made of a PEEK material, and a thickness t of the journal bearing is smaller than a thickness t1 with which a temperature in a contact surface thereof with the rotational shaft during an operation of the scroll compressor corresponds to a glass transition temperature.

Abstract: An artificial intelligence server includes: a communication interface configured to communicate with a terminal, and a processor. The processor is configured to receive, from the terminal through the communication interface, a video of a home appliance, acquire a first feature vector by inputting image data extracted from the video to an image classification model, acquire a second feature vector by inputting sound data extracted from the video to a voice classification model, acquire a result value by inputting a data set obtained by combining the first feature vector and the second feature vector to an abnormality classification model, and transmit, to the terminal through the communication interface, a failure type acquired based on the result value.

Abstract: Disclosed are an Intelligent electronic device and authentication method using message sent to intelligent electronic device. The method of authenticating using a message transmitted to the intelligent electronic device comprises the steps of: receiving a first message from a first external device; learning the received first message and extracting characteristics on a user of the first external device based on the learned first message; generating a template for the user of the first external device modeled based on the extracted characteristics on the user of the first external device; receiving a second message from a second external device; determining whether a unique identifier of the first external device is the same as a unique identifier of the second external device; and comparing the second message with the template to determine whether the user of the first external device is the same person as the user of the second external device, when the unique identifier of the first external device is the same as the unique identifier of the second external device. Accordingly, the fraud of impersonating another person can be prevented. The method of authenticating using a message transmitted to the intelligent electronic device of the present disclosure may be associated with an artificial intelligence module, a drone, a robot, an augmented reality device, a virtual reality device, a device related to a 5G service, and the like.

Abstract: A scroll compressor having a bearing is provided. The scroll compressor includes: a casing; a main frame fixed to the casing and having a shaft insertion hole formed therein; a fixed scroll fixed to the casing and disposed above the main frame; an orbiting scroll forming a compression chamber together with the fixed scroll and having a boss portion formed on a lower surface thereof; a rotational shaft having an end portion insertedly fixed in the boss portion in a state in which the rotational shaft is insertedly positioned in the shaft insertion hole; and a lubricating layer made of a PEEK material and formed in the shaft insertion hole or the boss portion, wherein the lubricating layer is formed by applying a liquid material to the shaft insertion hole or the boss portion.
