摘要:
An ink-jet printer head includes a base plate having ink channels penetrating through the base plate, through which ink is supplied, a hollow heat driving section formed in the base plate and encircling an exit of the ink channels, an ink chamber barrier stacked on the base plate for serving as a side wall of an ink chamber where ink is reserved, and a nozzle plate stacked on the ink chamber barrier and having a nozzle which communicates with the ink channels and the ink chamber coaxially. Accordingly, an area occupied by the unit nozzle can be reduced, and ink flow in the ink chamber is easily controlled, thereby enhancing a printing speed and a print quality.

An apparatus and method for routing on a mobile ad-hoc network are provided. The apparatus and method allow each node in a network to: measure a packet transmission rate to a neighboring node using a signal-to-noise ratio (SNR); measure variation in the number of nodes due to their insertion or deletion; distribute relative packet transmission time relative to the SNR, which is measured using the packet transmission rate; and determine a routing path using the stored relative packet transmission time relative to the SNR. The apparatus includes a transceiver that receives a reply packet from a neighboring node, a measuring unit that uses the reply packet to measure movement of the neighboring node and a relative packet transmission time thereto, and a routing path determination unit that uses the relative packet transmission time to determine a routing path in the network.

An apparatus and a method for allocating a channel capable of minimizing interference between channels in a node on an Ad-hoc network using a plurality of wireless interfaces for communication are provided. The apparatus includes a receiving unit that receives information on channel allocation from neighboring nodes, a channel search unit that searches for channels through which the node can communicate with all the neighboring nodes with reference to the received information on channel allocation, and a channel allocation unit that allocates a channel to the wireless interfaces based on the result of the search, so that it is possible to improve efficiency of network bandwidth usage and decrease interference of the channels.

A method of fabricating a color filter includes depositing an ink color in a pixel of a substrate using at least two printing process cycles, wherein at least one of a size of an ink droplet and a number of ink droplets is varied between the at least two printing process cycles.
摘要:
A semiconductor memory device including a clock buffer, a column selection line decoder, a control signal generation circuit, and a column selection line driver is provided. The clock buffer receives an external clock signal and information about a column address strobe (CAS) latency and generates either a first clock signal which synchronizes with rising edges of the external clock signal or a second clock signal which synchronizes with falling edges of the external clock signal depending on the type of CAS latency information. The column selection line decoder receives and decodes a column selection address and outputs a decoding address used to select either a column selection line signal synchronized with the first or second clock signal. The control signal generation circuit outputs control signals that synchronize with one of the first and second clock signals. The column selection line driver drives the column selection line signal in synchronization with one of the first and second clock signal in response to the decoding address and the control signals.
摘要:
A mechanism for establishing a wireless communication environment in which a wireless mesh network and a wireless local area network (LAN) are structured in a single plane and communicate with each other. A method of providing mobile station information includes obtaining information of at least one mobile station located in a wireless LAN from among a plurality of wireless LANs using a first frame received through the wireless LAN and transmitting a second frame including the obtained information over a network of mobile nodes including a mobile node that coordinates the wireless LAN.
