摘要:
The present invention provides a separator for a fuel cell that improves efficiency of the fuel cell by removing water generated in a membrane-electrode assembly and accumulated in a channel of the separator, a manufacturing method thereof, and a fuel cell stack including the same. The separator for the fuel cell of the present invention includes: a main body of a plate shape; a channel concavely formed in at least one surface of the main body and supplying a fuel or oxygen to a membrane-electrode assembly; and a metal layer provided to a surface of the channel and including an oxide layer formed by an anodic oxidation treatment and minute grooves of a nano-scale formed in the oxide layer, thereby forming the surface of the channel to be super-hydrophilic.

An anisotropically conductive layer ‘ACL’ for mechanical and electrical bonding of two circuit containing structures, such as a flip chip and carrier is disclosed. The ACL is formed of a rigid insulating substrate or membrane with a top and bottom planar surfaces formed with a plurality of pins therein. The pins extend beyond the top and bottom surfaces so that a portion of each pin is exposed. The pins provide electrical connection between contact terminals or pads of the flip chip and carrier and additionally provide mechanical support between the flip chip and carrier so that the flip chip can undergo post-bonding processing without substantial deformation or breaking. A method of electrically and mechanically bonding the flip chip and carrier and a method of making a semiconductor device using the ACL is also disclosed.

A polyester tire cord is produced from a polyester multi-filamentary yarn having a novel internal microstructure containing crystalline, amorphous and mesomorphous portions which are changed to a definite structure of crystalline and amorphous portions during formation of the tire cord. A polyester resin containing at least 90 mol % polyethylene terephthalate is melt-spun and solidified by quenching to produce an undrawn yarn with a birefringence of 0.03 to 0.08, which is then drawn at a total draw ratio of 1.4:1 to 2.2:1 and thermally treated and relaxed. The resulting filamentary yarn is dipped in a rubber solution to produce a tire cord which exhibits excellent dimensional stability and fatigue resistance when it has been incorporated into a rubber matrix of a tire.

Disclosed is a method of measuring audience ratings for at least more than one service and content in a terminal. The measurement method may include receiving a campaign invitation message for an audience measurement campaign from a server. The campaign invitation message may include at least more than one of information for the audience measurement campaign, information for the server, and information for an opt-in rate of the audience measurement campaign. The method may further include authenticating the information for the server in the campaign invitation message. The method may further include determining whether to participate using the information for the opt-in rate of the audience measurement campaign in the campaign invitation message. The method may further include transmitting a panel opt-in request message to the server according to the determination result. The method may further include receiving a panel opt-in response message from the server.

An anisotropically conductive layer “ACL” (50) for mechanical and electrical bonding of two circuit containing structures, such as a flip chip and carrier is disclosed. The ACL is formed of a rigid insulating substrate (72) or membrane (61) with a top and bottom planar surfaces formed with a plurality of pins therein. The pins extend beyond the top and bottom surfaces so that a portion of each pin is exposed. The pins provide electrical connection between contact terminals or pads of the flip chip and carrier and additionally provide mechanical support between the flip chip and carrier so that the flip chip can under go post-bonding processing without substantial deformation or breaking. A method of electrically and mechanically bonding the flip chip and carrier and a method of making a semiconductor device using the ACL is also disclosed.

A polyester multi-filamentary yarn having a novel internal microstructure, polyester tire cord produced from the yarn and a process for production thereof are provided. The polyester yarn has a novel three-phase microstructure consisting of crystalline, amorphous and mesomorphous portions which are changed to a structure having crystalline and amorphous portions during formation of a tire cord. The polyester resin contains at least 90 mol. % polyethylene teraphthalate. The resin is melt-spun and solidified by quenching to produce an undrawn yarn having a birefringence of 0.03 to 0.08, which is then drawn at a total draw ratio of 1.4:1 to 2.2:1 and thermally treated and relaxed. The resulting filamentary yarn is dipped in a rubber solution to produce a tire cord which exhibits excellent dimensional stability and fatigue resistance when it is incorporated into the rubber matrix of a tire.

A system and a method for stabilization control may control position and direction of an object having first and second bodies connected to each other. The system may include an artificial vestibular apparatus for outputting a movement signal corresponding to movement of the first body and a rotation signal corresponding to rotation of the first body; a translating actuation unit connected between the first and second bodies and controlling position of the second body in response to the movement signal; and a rotating actuation unit connected between the first and second bodies and controlling rotation of the second body in response to the rotation signal. If the system and the method are applied to a vision system of a mobile robot, the vision system may obtain stabile image information even when the mobile robot is moving. Thus, it is possible to prevent any blurring from occurring at the image information.
