Abstract:
In a bipolar plate of a fuel cell and a fabrication method thereof, the bipolar plate of the fuel cell includes a plate; a fluid flowing space formed on both sides of the plate; a fluid guide mesh installed on the fluid flowing space; an inflow path formed on the plate to be connected with the fluid flowing space; and an outflow path formed on the plate to be connected with the fluid flowing space. Also, in the fabrication method, the bipolar plate is fabricated with a certain mold and by a processing method. Accordingly, it is possible to uniformize flux distribution and reduce flow resistance of fuel and air respectively flowing into a fuel electrode and an air electrode of a fuel cell. In addition, reaction area with a M.E.A and diffusion zone can be increased, and fabrication can be simplified and facilitated.
Abstract:

The home network system includes: at least one new device including a node address having an initial logical address through a network based on a predetermined protocol, transmitting a configuration request message having the node address to a master device, receiving a temporary address setting request message, changing the initial logical address by selecting one temporary logical address, generating a temporary address setting response message, transmitting the temporary address setting response message to the master device, receiving an address change request message having a predetermined logical address from the master device, changing the temporary logical address into the received logical address, and having a unique node address; and at least one master device for receiving the plurality of configuration request messages from the new device, setting the temporary logical address range for the new device, transmitting the temporary address setting request message having the set temporary logical address range to the new device, receiving the temporary address setting response message from the new device, setting the predetermined logical address of the new device, and transmitting the address change request message having the set logical address to the new device of the selected temporary address.
Abstract:
A rotary compressor having two different compression capacities is provided. The rotary compressor may include a driving shaft that is rotatable in both a clockwise and counterclockwise direction, and having an eccentric portion at an end thereof. The compressor may also include cylinder having a predetermined inner volume, and a roller rotatably installed on an outer circumferential portion of the eccentric portion so as to contact an inner circumference of the cylinder and form a fluid chamber therebetween. A vane is elastically installed in the cylinder and contacts the roller, and upper and lower bearings are respectively installed at upper and lower portions of the cylinder so as to rotatably support the driving shaft and hermetically seal the inner volume of the cylinder. Suction and discharge ports communicate with the fluid chamber based on a rotational direction of the driving shaft so as to provide a different compression capacity depending on the rotational direction of the driving shaft.
Abstract:
The present invention discloses a home network system using a living network control protocol. The home network system includes: at least two electric devices (e.g., a first and a second electric device); and a network based on a predetermined network for networking the electric devices, wherein the first electric device sends a request message to the second electric device, and the second electric device sends a response message to the first electric device, wherein the response message transmitted from a lower layer to an upper layer of the second electric device is transmitted to a lower layer and then to an upper layer of the first electric device, and includes a command code included in the request message, for indicating an operation for the second electric device to execute, and a field related to an execution of the request.
Abstract:
The present invention discloses a home network using a living network control protocol. The home network system includes: a network based on a predetermined protocol; at least electric device connected to the network; and a network manager connected to the network, for controlling and/or monitoring the electric device, when the protocol includes an application layer for handling a message for controlling and monitoring the electric device, a network layer for network-connecting the electric device to the network manager, a data link layer for accessing shared transmission medium, and a physical layer for providing a physical interface between the electric device and the network manager, wherein the physical layer further includes a special protocol for providing an interface with a dependent transmission medium, and the network layer further includes a home code control sub-layer for managing a home code for network security when accessing the dependent transmission medium.
Abstract:
A method for setting a product address in a home network system is disclosed. The method includes a step for requesting a temporary address in which a network controller designates redundant addresses with a predetermined range to each product and requests an arbitrary address among the redundant address as a temporary address; a step for designating a temporary address in which each product designates an arbitrary address among the redundant addresses as a temporary address and informs to a network controller; and a step for confirming an address in which the network controller sequentially sets one of the redundant addresses for each address not doubled among informed temporary addresses from each product.
Abstract:
An apparatus for fixing an eletrode of an electrode of plama polymerization apparatus is provided, which comprises; a nonconductive holder for fixing an electrode by covering an end part of the electrode, a leadline connecting the electrode with a power supply, and a fixing part fixing the holder on a chamber wall.
Abstract:
Disclosed is a network control system for home appliances that satisfies the characteristics of low-cost and high-efficiency with respect to currently used appliances adopting a low-performance microcomputer. The system is constructed to define a master/slave type communication structure with respect to the respective appliances; construct a network by connecting the appliances through the serial communication function; and enable the appliances to communicate with one another if a predetermined communication event is produced. According to the system, an optimized network for the home appliances can be implemented, and operation states of the respective appliances can be displayed through the co-operation among the appliances, thereby maximizing the user convenience.
