Disclosed is a rotor including a sleeve part having a shape corresponding to a cylinder extending in a reference direction, and having an inner hole extending in the reference direction, in an interior thereof, a division part disposed in the inner hole, and dividing the inner hole into a first space and a second space, together with the sleeve part, a first magnet part disposed in the first space, and a second magnet part disposed in the second space, and disposed to have an opposite polarity to that of the first magnet part when viewed along the reference direction.

Rotor and sensorless control method for rotor

One embodiment of the present invention relates to an electronic device for reproducing, in time sequence, first pen data in which handwriting strokes are digitized on a medium by an electronic pen. The electronic device comprises: a communication module; a control module; an output module for reproducing or outputting first handwriting information, first image or audio information photographed or recorded by the electronic device, and event information in time sequence; and a memory module for storing contents including the first handwriting information, the first image or audio information, and the event information, wherein, when the communication module further receives second pen data in a state where the first handwriting information is held on the output module after the contents are stored in the memory module, second handwriting information corresponding to the second pen data is added to the first handwriting information and then reproduced.

Electronic device, method for driving electronic device, and method for controlling data recording application

A wafer level fan out semiconductor device and a manufacturing method thereof are provided. A first sealing part is formed on lateral surfaces of a semiconductor die. A plurality of redistribution layers are formed on surfaces of the semiconductor die and the first sealing part, and solder balls are attached to the redistribution layers. The solder balls are arrayed on the semiconductor die and the first sealing part. In addition, a second sealing part is formed on the semiconductor die, the first sealing part and lower portions of the solder balls. The solder balls are exposed to the outside through the second sealing part. Since the first sealing part and the second sealing part are formed of materials having thermal expansion coefficients which are the same as or similar to each other, warpage occurring to the wafer level fan out semiconductor device can be suppressed.

Wafer level fan out semiconductor device and manufacturing method thereof

According to one embodiment of the present invention, there is provided an electronic pen including a first pen module which includes a first pen core including a writing material used for a medium and a pattern sensing unit configured to acquire a handwritten image of a user in order for the electronic pen to acquire first location information that is location information of the electronic pen with respect to the medium, a second pen module which generates at least one of a magnetic field and an electronic field in order for the electronic pen to acquire second location information that is location information of the electronic pen with respect to an electronic device, a main body in which the first pen module is disposed at a first end portion thereof and the second pen module is fixed to at least one of the first end portion and a second end portion thereof and which has a cavity therein, and a control unit which generates a signal for controlling the first pen module and the second pen module.

Electronic pen, electronic device, and method of controlling the same

An electronic apparatus includes: a communicator configured to communicate with an intermediate server and an other electronic apparatus; a memory in which an encryption key and a decryption key generated by the electronic apparatus are stored; and a controller configured to transmit the encryption key generated by the electronic apparatus to the other electronic apparatus through the intermediate server and performs control such that a network with the other electronic apparatus is formed.

Electronic apparatus, method of controlling the same, and network system thereof

A user terminal device, which can execute an application created based on a dynamically typed language, such as JavaScript, a server, which provides reference information for compilation, and an application executing control method thereof are provided. The user terminal device includes a communicator configured to communicate with at least one server; a storage configured to store data of a source code of an application; and a processor configured to transmit identification information of the source code of the application to the at least one server, receive reference information for compiling the source code corresponding to the transmitted identification information from the at least one server, and compile the source code of the application into a machine code based on the received reference information.

User terminal device, server, and application execution method thereof

Disclosed herein is a natural gas liquefaction process using a single refrigeration cycle adopting a mixed refrigerant, and therefore having a simple structure and thus a compact system which is easy to operate, and further, after the mixed refrigerant is separated into two refrigerant parts, the two refrigerant parts are not mixed with each other but go through condensing (cooling), expanding, heat-exchanging, and compressing stages individually, and thus, optimal temperature and pressure conditions are applied to each of the separated refrigerant parts to increase efficiency of the liquefaction process.

Natural gas liquefaction process

De-airing of PVB/glass laminates can be improved, while haze in the pre-press is minimized and sleep time reduced as a result using a PVB sheet having a roughened surface with directionality. A roughened surface with a washboard pattern that is useful in this regard can be obtained by varying certain conditions of a melt-fracture extrusion process.

Radiator for electronic parts

A liquid fire extinguishing composition is obtained by mixing a C.sub.1 -C.sub.5 halogenated alkane such as Halone 1301 (CF.sub.3 Br), Halone 1211 (CF.sub.2 ClBr), or a mixture thereof with an organophosphorus compound, or the mixture thereof for a wide variety of a fire extinguishment and no residues after fire extinguishing.

Liquid fire extinguishing composition

A new process for the preparation of a 3-(4'-bromobiphenyl-4-yl)tetralin-1-one known as a key intermediate for the production of rodenticides and clinical medicines is provided. The title compound is prepared from P-bromobiphenylbenzylketone in three steps, wherein one of key inventions is dehydroxylation of 3-(4'-bromobiphenyl)-3-hydroxy-4-phenylbutyric acid ethyl ester using trialkylsilane in trifluoroacetic acid. This new process offers a high yield with a facile way and is more suitable for a commercial production than the prior art methods.
