Abstract:
PURPOSE: A polysulfone-based polymer, a polymer electrolyte membrane including thereof, an membrane electrode assembly including thereof, a fuel cell, and a manufacturing method of the polysulfone-based polymer are provided to secure the high hydrogen ion conductivity, and the low methanol transmittance. CONSTITUTION: A polysulfone-based polymer includes a recurring unit marked with chemical formula 1. In the chemical formula 1, X is a single bond or Ar1. The Ar1 is a substituted or non-substituted arylene with 6~20 carbons. M1 and M2 are hydrogen, lithium, sodium, or potassium, independently. R1, R2, R3, and R4 are a linear or branched alkyl group with 1~20 carbons, an alkenyl group with 2~20 carbons, an alkynyl group with 2~20 carbons, a cycloalkyl group with 5~20 carbons, an aryl group with 6~20 carbons, a heteroaryl group with 2~20 carbons, an alkyl aryl group with 7~20 carbons, and an alkoxy group with 1~20 carbons.
Abstract:
PURPOSE: A vehicle open detecting method using a pressure sensor is provided to allow a driver to easily recognize the open of a window by determining the open of an opening unit through change of indoor pressure and by informing the driver. CONSTITUTION: Whether a key is removed is determined after starting is stopped so that a driver gets off. When the removal of the key is determined, the opening of an opening unit is determined by determining change of indoor pressure sensed through a pressure sensor. When the change of the indoor pressure is determined, the opening of the opening unit is determined and is warned.

Abstract:
PURPOSE: A locking device of a vehicle slide door is provided to increase safety and convenience of a passenger by preventing the generation of safety accidents of the passenger. CONSTITUTION: A remote control lever(50) is included in a slide door and releases locking state of a door latch(13) according to operation of a door inside handle(11) and a door outside handle. A stopper(70) is placed on the slide door and restricts movement of the slide door when the slide door contacts a door rail. A master switch device(80) is placed on the slide door and connected to the remote control lever by the medium of an input cable(61). The master switch device is connected to the stopper by the medium of an output cable(63) and connects or blocks power transmission between the input cable and the output cable.
