A coupling member that is attachable to/detachable from a housing of an electronic device while making the housing wearable on a user's body, and an electronic device including the coupling member is provided. The electronic device includes a band member that is configured to come in contact with a user's body portion, a slide member that is mounted on the band member, and is bound to a portion of the housing in a state where the coupling member is mounted on the housing, an opening that is formed in the slide member, a locking member that is disposed on the band member, and a locking protrusion that is formed on a locking member. The locking protrusion appears to the outside of the slide member through the opening according to the reciprocating of the locking member, and the coupling member is bound to the housing.

Coupling member and electronic device including the same

Disclosed is an electronic device electronic device that has a single part, which allows a wheel dial to be fixed to a housing of the electronic device, and prevents the wheel dial from moving horizontally and vertically relative to the housing.

Electronic device with rotatable structure

A semiconductor device according to example embodiments may include a channel including a nanowire and a charge storage layer including nanoparticles. A twin gate structure including a first gate and a second gate may be formed on the charge storage layer. The semiconductor device may be a memory device or a diode.

Semiconductor device and method of manufacturing the same

The wheel-type high-speed railway system includes rails provided on a railroad track and configured such that wheels provided in a bogie of a vehicle come into contact with them, a support provided on a tread surface of a railroad track between the rails, a repulsive Linear Synchronous Motor (LSM) provided between the bogie and the support and configured to improve traveling performance by reducing axle load in a high-speed region, first and second steel plates mounted on both sides of the support in inclined positions, and first and second attractive Dynamic Motion Control (DMC) magnets mounted on the bogie of the vehicle in inclined positions to correspond to the first and second steel plates, and configured to generate attractive force.

Wheel-type ultra high speed railway system

Provided is a tube railway system that reduces noise and air resistance using a sealed evacuated tube as a passage for a tube railway, thereby allowing a train to run at a higher speed. A vacuum division management system and a vacuum blocking screen device for a tube railway system required to maintain vacuum are provided, in which the vacuum blocking screen device is operated to rapidly block a passage for a tube railway in response to an operation signal, is installed at every certain section or at a designated section of the tube railway, and is operated in a specific section when a vacuum maintenance problem occurs, or when the vacuum needs to be released, or when the train needs to stop immediately, thereby allowing the specific section to be isolated from other sections to have a degree of vacuum different from those of the other sections.

Vacuum division management system and vacuum blocking screen device for tube railway system

A wireless communication interface for a portable wireless terminal and a system for wirelessly communicating by a portable wireless terminal with another device via a free space. The interface facilitates aligning the portable wireless device with another devices for improved communication. The interface including: a light source for generating a data-modulated visible light signal and outputting the visible light signal to the free space; an optical detector for generating an electrical signal by photoelectrically converting the visible light signal input from the free space, and for outputting the electrical signal. A demodulation unit demodulates the electrical signal input from the optical detector, and outputs a data signal.
