The present invention provides a silane oligomer for immobilizing a physiological material that is prepared by copolymerizing an aminosilane compound with a cyclic siloxane oligomeric compound. The present invention can preserve the immobilization layer by applying a silane oligomer. Further, the immobilization layer has a three-dimensional structure and thus has superior thermal stability and reagent resistance.

A composition for a transparent conductive layer, a transparent conductive layer formed of the composition, and a method for forming the transparent conductive layer. The composition comprises a metal (M.sub.1) particle, a binding agent and a solvent, wherein the metal (M.sub.1) particle has an average particle diameter of 10.about.30 nm and is at least one selected from the group consisting of gold (Au), silver (Ag), platinum (Pt), copper (Cu), nickel (Ni), lead (Pb), cobalt (Co), rhodium (Rh), ruthenium (Ru), palladium (Pd) and tin (Sn), and wherein the binding agent is at least one compound selected from the group consisting of polypyrrole, polyvinylpyrrolidone, polyvinylalcohol and silicon alkoxide oligomer. Therefore, the transparent conductive layer which is excellent in conductivity and transmittance can be formed by a low-temperature sintering process.

A fail-safe air flap control apparatus for a vehicle includes a coolant temperature sensor, a control unit, an actuator, a movable unit, a flap unit, an elastic member and a solenoid unit. The coolant temperature sensor measures the temperature of a coolant. The control unit compares a value measured by the sensor to a reference value and generates a corresponding control signal. The actuator has a rotator which rotates in a clockwise or counterclockwise direction depending on the control signal. The movable unit linearly moves under rotational force of the rotator. The flap unit includes a flap housing having an air flow slot, a flap door mounted to the flap housing to openably close the air flow slot, and a connecting rod connected to the movable unit. The elastic member applies elastic force to the movable unit in a direction in which the flap door opens. The solenoid unit is controlled by the control signal of the control unit so as to either restrain movement of the movable unit and so maintain the flap door in a closed state or to release the movable unit.

A light emission device for simplifying a structure of an electron emission unit and a manufacturing process thereof is provided. A display device using the light emission device as a light source is also provided. The light emission device includes a vacuum panel having a first substrate and a second substrate facing each other. A sealing member is between the first and second substrates. Recesss portions each have a depth into a side of the first substrate facing the second substrate. Cathode electrodes are in corresponding recesses. Electron emission regions are on corresponding cathode electrodes. A gate electrode is fixed at one side of the first substrate at a distance from the electron emission regions. A light emission unit is at one side of the second substrate. The gate electrode includes a mesh unit having openings for passing through an electron beam and a supporting member surrounding the mesh unit.
