摘要:
A fluorinated resin having enhanced wettability to water prepared by roughening a surface of the fluorinated resin such that a central line roughness average (Ra) of the surface is increased to at least 0.1 &mgr;m, and then depositing thereon a thin hydrophilic film while maintaining the central line roughness average (Ra) of at least 0.1 &mgr;m, the thin hydrophilic film being formed from a hydrophilic substance having a contact angle of water of less that 90°, and the resulting fluorinated resin having up to 20° of contact angle of water. The fluorinated resins are able to maintain high hydrophilicity even after prolonged exposure to the atmosphere and can be used in various fields that require bio-compatibility and in permeable membranes or filters.

The present invention relates to an electric vehicle and to a method for controlling same. The electric vehicle according to the present invention comprises: a sensor unit including a first sensor and a second sensor; and a vehicle control unit including a main processing unit and a sub-processing unit for taking, as an input, signals from the sensor unit and performing an operation. The main processing unit takes, as an input, a first sensor value measured by the first sensor and a second sensor value measured by the second sensor, and compares the first sensor value and the second sensor value so as to obtain a first difference value. The sub-processing unit takes, as an input, a second difference value obtained from the difference between the first sensor value and the second sensor value. The main processing unit or the sub-processing unit compares the first difference value and the second difference value in order to determine the state of the vehicle and control the travel of the vehicle.

An adjustable length adapter incorporates a driving motor on the inside and is coupled with a rotation tool at one side, wherein a rotation shaft protrudes from the rotation tool and rotates when the driving motor is driven. The adapter includes a coupling member formed with a through-hole at one side to be penetrated by the rotation shaft, wherein the rotation tool is coupled at one side of the rotation tool, a main body having a supporting member formed at the other side of the coupling member, a varying section having one side coupled with the supporting member and withdrawable therefrom, and the other side is formed with a rotation shaft to be coupled with an exchangeable working member, a driving pulley disposed on top of the main body and coupled with the rotation shaft, a driven pulley coupled with the rotation shaft of the varying section, and a belt coupled between the driving pulley and the driven pulley for rotating the driven pulley when the rotation shaft protruded from the rotation tool rotates. The main body of the adapter coupled at a side of the rotation tool is coupled with a varying section, which is coupled with a working member such as a cutting blade or the like, in such a manner that the length of the varying section is adjustable so that the length is adjusted according to the state of an object, thereby enabling easy machining of the object.

Provided is a cell case for secondary batteries which protects and supports a bare cell. The cell case has vents, thus enhancing the cooling efficiency of the bare cell. A heat exchanging member is formed in an outer surface of the cell case so that the bare cell can directly dissipate heat to the air through the heat exchanging member. Therefore, the efficiency of cooling the bare cell can be enhanced, thereby improving the performance of the secondary battery.

The present invention relates to a system for charging an electric vehicle and to a method for charging the electric vehicle. A charging stand which supplies electric power for charging to the electric vehicle performs user authentication or vehicle authentication for the electric vehicle to be charged, so as to prevent unauthorized charging or theft and thus enable the electric vehicle to be stably charged. In addition, a connection circuit is used as a connection cable or a connector for charging, which interconnects the vehicle and a charging side by means of a single line to enable both the vehicle and the charging side to recognize the interconnection, thus simplifying the configuration of the circuit for enabling the vehicle and the charging side to recognize the interconnection, and enabling both the vehicle and the charging side to easily recognize whether or not they are interconnected.
