The motor structure according to the preferred embodiment of the present invention includes: a fixing body, a shaft fixed to the fixing body, a bearing rotatably fitted on the shaft, a rotating body fixed to an outer side of the bearing and rotated by electromagnetic force, a case fixed to the fixing body and having the shaft, the bearing, and the rotating body accommodated in an inner space thereof, and a washer fixed to a top inside of the case so as to be interposed between the top inside of the case and a top surface of the bearing and contacting a part of the top area of the bearing.
Abstract:
A home appliance system and an operation method thereof are disclosed. The home appliance outputs product information as a predetermined sound and transmits the sound through a connected communication network, thereby making it easier for a service center at a remote place to check a status of the home appliance. Further, the home appliance system and operation method thereof prevents noise or signal error generated in the procedure of converting product information into a signal of a predetermined frequency band in order to output the product information as a sound, thus enabling stable signal conversion and improving the accuracy of information transmission using the output of sound.
Abstract:
Disclosed are a plug interlock device for a circuit breaker and a circuit breaker having the same, wherein a plug is not allowed to be separated from a connector while a breaker main body is moved from a test position to a run position or is running at the run position, thereby obviating the plug from being unexpectedly unplugged from the connector while the breaker main body is moved from the test position to the run position or is running, resulting in preventing a safety accident in advance.
Abstract:
There is provided a flat type vibration motor 100 that includes a bracket 150 with a shaft 140 of which one end is inserted into and fixed to the center thereof, a printed circuit board 110 having a terminal portion 130 receiving external electricity and disposed on the side of the bracket 150, a stator disposed on the top of the printed circuit board 110, a rotor 170 rotatably installed in the shaft 140 and generating vibration while rotating by interaction with the stator 160, and a stopper 180 installed at the other end of the shaft 140. The bracket 150 and the shaft 140 are electrically connected with the terminal portion 130. Further, it is possible to use the bracket or a shaft as an external power connection terminal by electrically connecting a negative terminal to the bracket and the shaft through the contact portion.
Abstract:
The present invention relates to a remote monitoring system and a method controlling the same, which can selectively monitor according to a condition of power and a control of devices including a washer and a dryer installed in a remote place. The remote monitoring system comprises a communication module provided in each device for transmitting monitoring information after identifying an operation condition of each device according to a user's demand; and a remote monitoring unit for selecting a device to be monitored based on a result after identifying a power condition of each device, as well as displaying an operation condition of each device based on the transmitted monitoring information and the control of each device.
Abstract:
Disclosed are a position switch and a circuit breaker having the same. As contact plates having an elastically variable height are provided between switch blocks and switch levers, each of a testing contact plate and a running contact plate may compensate for inferior dimensioning of the switch blocks and the switch levers. This may allow a position of a breaker body to be rapidly and precisely displayed, and may prevent damage of the position switch provided at the breaker body. Furthermore, connection inferiority between a terminal of the breaker body and a terminal of a cradle may be prevented.
Abstract:
Disclosed is a robot cleaner system having superior functions of sucking dust and exhausting dust to a docking station. The robot cleaner includes a dust suction port to suck dust, a dust collecting chamber to collect dust introduced through the dust suction port, a dust exhaust port to exhaust dust collected in the dust collecting chamber to the docking station, a connection path extending from the dust suction port to the dust exhaust port in adjacent to the dust collecting chamber, and a valve device provided between the connection path and the dust collecting chamber, an opening/closing of the valve device allowing the dust collecting chamber to selectively communicate with the dust suction port or the dust exhaust port according to a pressure difference between the dust collecting chamber and the connection path.
Abstract:
A diagnostic server and a controlling method are provided. In the method, the diagnostic server receives a packet including at least one frame and performs error checking on each frame included in the packet. The diagnostic server receives a retransmitted packet upon determining from the result of error checking that a frame in the packet has an error. The diagnostic server performs error checking on each frame included in the retransmitted packet and restores the frame included in the packet based on the retransmitted packet when a frame, which is located in a location corresponding to the error frame, included in the retransmitted packet has no error. In the case where a packet including product information is transmitted, this method can reduce the number of retransmissions of the same packet required to acquire an error-free packet.
Abstract:
A method for preparing a ZnO nanocrystal directly on a silicon substrate includes the steps of: (S1) forming a Zn—Si—O composite thin film on the silicon substrate; and (S2) thermally treating the obtained thin film. Particularly, ZnO nanocrystals are formed in an amorphous Zn—Si—O composite thin film by controlling the composition of the Zn—Si—O composite thin film and heating temperature thereof. With the present invention method for preparing a ZnO nanocrystal directly on a silicon substrate, more possibilities are opened up for the applications of ZnO nanocrystals to an optoelectronic device in use of a silicon substrate.
Abstract:
A method for implementing a redundant structure of an ATCA system via a base interface of a network system based on an ATCA standard, and the ATCA system for use in the same are disclosed. Each of routing protocol shelves and LI shelves includes two ports connected to two IPC paths provided from the base interface, such that a representative IP address is assigned to a single port to be used, performs IPC communication using the representative IP address. If a port error or link-down state occurs, the representative IP address is assigned to the other port, resulting in the implementation of stable IPC communication. If the port error or link-down state occurs in an active-mode ShMC shelf, an IPC path passing through a standby-mode ShMC shelf is provided.
