摘要： Provided is a turbo compressor capable of compressing a gas and supplying the compressed gas to outside, the turbo compressor including a compression unit including an impeller for compressing a gas introduced through a compressed gas inlet, a motor including a rotating shaft having an end coupled to the impeller, to rotate the impeller, a housing including a motor accommodation space for accommodating the motor, a cooling air channel provided to pass through the motor accommodation space and formed to continuously circulate a cooling gas accommodated therein, one or more air bearings supporting a radial load or an axial load of the rotating shaft, and a non-contact explosion-proof unit provided as a passage through which flames produced in an inner space of the housing pass so as to be cooled and then discharged to the outside, and having a width less than or equal to a predetermined value and a length greater than or equal to a predetermined value, wherein a compressed gas channel is spatially separate from the cooling air channel to prevent the gas inside the compressed gas channel from penetrating into the cooling air channel. According to the present invention, an explosion-proof turbo compressor with an improved structure to increase service life and reduce vibration noise by using air bearings and to, at the same time, rapidly cool and then discharge flames caused by an internal explosion may be provided.

摘要： The present invention relates to a cobra automatic fire extinguishing device capable of loading a fire extinguisher. The cobra automatic fire extinguishing device can automatically spray extinguishing fluid to a location of a fire by mounting a fire extinguisher inside, detecting the location of the fire, and directing the nozzle to the location of the fire. In addition, the cobra automatic fire extinguishing device can be installed economically since it does not require additional cost and time for manufacturing a separate, dedicated fire extinguisher and certification procedure. Furthermore, the cobra automatic fire extinguishing device can effectively extinguish a fire by precisely spraying the extinguishing liquid to the location of the fire, and can prevent conflagration by suppressing the initial fire.

摘要： The present invention relates to a drone. The drone includes a main body, a plurality of blades, a plurality of driving motors, a power supply unit, a control unit, a plurality of sensors, and a plurality of switch units, and the switch units are connected to turn on and off power supplied to the driving motor that drives a blade corresponding to the sensor so that the main body does not collide with the obstacle. The blades are mounted on the main body. The driving motors correspond to the respective blades. The power supply unit supplies power. The control unit controls power. The sensors are installed to correspond to the respective blades. The switch units receive a signal detected by one of the sensors and turn on and off the direct supply of power to a corresponding one of the driving motors.

摘要： The present invention relates to an identification polymer label for inspection and maintenance of parts and an identification method using the same. The present invention provides a durable polymer material label including: a color change layer matrix containing a resin in which a hydrophilic polymer and a hydrophobic polymer are crosslinked; and a pigment layer matrix containing an aqueous pigment in the resin. Due to the stability against discoloration, moisture resistance, and durability of the color change layer matrix and the pigment layer matrix, the polymer label is effective for long-term identification of production information, and waterlogging thereof may be identified. Due to the aqueous fluorescent pigment contained in the pigment layer matrix, even when the identification label is attached to a dark place or and a deep portion or even at night, it may be visually recognized by visual inspection or optical detection.

摘要： The present invention provides a microspeaker having a water drainage structure capable of rapidly discharging water, entering the microspeaker, to the outside. In the case of a woofer-tweeter speaker, water is discharged through the side and bottom of a housing, and in the case of a 1-way speaker, water is discharged through the side of a housing. In addition, the present invention provides a connection portion that is formed to position a plurality of soldering points, to which a woofer wire and a tweeter wire are bonded, not outside a driver but inside or at the boundary of a space formed by the driver in a TWS-type 2-way microspeaker. This secures design freedom and save space by reducing the overall length of a small speaker.

摘要： The present invention is configured to compare a signal strength based on a position value of a wireless LAN AP recorded in a wireless LAN AP position database (120) with a signal strength based on the wireless LAN AP information of nearby wireless LAN APs and a detected position value obtained through actual search performed by position detection devices (88 and 84). When the signal strength based on the wireless LAN AP information of the nearby wireless LAN APs and the detected position value obtained through actual search performed by the position detection devices (88 and 84) is higher, it means that the detected position value is closer to a corresponding wireless LAN. Accordingly, the position value of the corresponding wireless LAN AP in the wireless LAN AP position database (120) and the signal strength are updated by being replaced with the value obtained through the actual search.
