Abstract: A novel quinazoline compound having SOS1 inhibitory activity and uses of the quinazoline compound are disclosed. More particularly, the present invention relates to a novel quinazoline derivative compound having inhibitory activity on SOS1 binding to RAS family proteins and/or RAC1, to pharmacologically acceptable salts thereof, and to pharmaceutical compositions containing the quinazoline compound. The novel quinazoline compound has the following chemical formula 1: wherein all the variables have meaning as defined in the specification.

Abstract: A reprint apparatus may include: a defect checking unit configured to check a defective portion in a solder resist layer of a circuit board; a material filling unit positioned above the circuit board to fill the defective portion with a filling material; and a curing unit configured to cure the material filled in the defective portion. The defect checking unit may be configured to calculate a volume of the defective portion, and the material filling unit may be configured to calculate a discharge amount of the filling material based on the calculated volume of the defective portion, and then discharge the filling material by the discharge amount.

Abstract: A display device includes a first area in which a foreign substance is disposed and a second area in which the foreign substance is not disposed. The display device includes a lower panel including a base layer, a display element layer, and an encapsulation layer, an upper panel disposed on the lower panel and including a light control layer and a color filter layer, and a filling layer filling a space between the lower panel and the upper panel. A distance between the display element layer and the light control layer in the first area is greater than a distance between the display element layer and the light control layer in the second area. Accordingly, defects caused by the foreign substance are prevented, and a display quality and a reliability of the display device are increased.

Abstract: Provided is a PROX (preferential oxidation) reaction apparatus for a fuel cell, which includes a mixing chamber to which a reforming gas and a PROX air are introduced, a reforming gas supply tube disposed in the mixing chamber to supply a reforming gas, a heat exchange chamber connected to an upper portion of the mixing chamber, a disk disposed between the mixing chamber and the heat exchange chamber, a cooling water circulation module connected to the heat exchange chamber, and a PROX catalyst chamber disposed above the heat exchange chamber, wherein the reforming gas supplied through a lower portion of the mixing chamber performs multi-stage mixing while passing through the mixing chamber and the disk.

Abstract: Provided is a fuel reformer for a fuel cell system, which includes an autothermal reforming reactor having an autothermal reforming reaction catalyst and configured to produce a reforming gas with abundant hydrogen by using a hydrocarbon-based fuel, water and air, an ATO reactor configured to produce a high-temperature combustion gas by burning a fuel-containing tail gas discharged from a fuel cell stack, and an ATO heat exchanger configured to increase a temperature of a mixture of water and air supplied to the autothermal reforming reactor, by using the combustion gas produced by the ATO reactor.

Abstract: An apparatus for manufacturing molten iron includes a reduction furnace having a charging device that is capable of preventing segregation. The reduction furnace for reducing an iron-containing material used for manufacturing molten iron may include a charging hole where the iron-containing material is charged, a first guide plate sloped toward a first direction in the reduction furnace to guide the iron-containing material to the inside of the reduction furnace, and a second guide plate fixed and sloped toward a second direction intersecting the first direction in the reduction furnace to guide the iron-containing material dropped and guided by the first guide plate. A dropping direction of the iron-containing material dropped and guided by the first guide plate is changed when the iron-containing material is guided by the second guide plate.

Abstract: A link structure of a power tailgate is disclosed in which the links opening and closing the tailgate move perpendicularly in relation to the rotational direction of the driving motor, thereby preventing an overload of the motor. Accordingly, a small capacity motor may be used for reducing the weight and raw material cost thereof. Further, as the orientation of the links is in the longitudinal direction of the vehicle body, a compact link construction is provided. Such the structure includes a rack gear meshing with a driving gear of the motor, and a multi-joint link connected at both ends thereof to the rack gear and tailgate, respectively. The multi-joint link is constituted by a plurality of link members relatively and pivotally connected to each other by means of pins.
