Abstract: A memory may include a first wafer, and a second wafer stacked on and bonded to the first wafer. The first wafer may include a cell structure including a memory cell array; and a first logic structure disposed under the cell structure, and including a row control circuit. The second wafer may include a second logic structure including a column control circuit.

Abstract: A radiator bushing mounted in a vehicle body to support a load of a radiator includes a mounting portion having an outer side fixed to the vehicle body, a center core at a center with a center hole, and a support portion having an inner side and an outer side. The support portion includes a first support portion and a second support portion with an inclined angle ? of the first support portion and an inclined angle ? of the second support portion are determined to be different. The support portion has a two-stage structure in which inclined angles are different, and a direction ratio of a Z axis direction to an X axis direction and a Y axis direction may be easily adjusted.

Abstract: An exhaust heat recovery apparatus for a vehicle, may include a case having an inlet and an outlet, a heat exchange part mounted in the case, the heat exchange part, a bypass tube connecting the inlet and the outlet of the case in the case, having an inflow opening for the inflow of the exhaust gas to the heat exchange part, and allowing an exhaust gas to bypass the heat exchange part, and a variable valve installed in the bypass tube to selectively block flow of the exhaust gas through the bypass tube and induce the exhaust gas to the heat exchange part, wherein the heat exchange part includes a coolant distribution member having a plurality of coolant paths connected to and spaced apart from each other between the bypass tube and the case, and a lubricant distribution member installed in one of the coolant paths and in which the lubricant flows.

Abstract: An exhaust device for a vehicle, the vehicle including a vehicle body, a fuel tank protruding from a bottom surface of the vehicle body, and a suspension system that supports first and second rear wheels to the vehicle body. The exhaust device is configured to be connected to a gas exhaust through-hole of an engine and includes a muffler that is disposed laterally alongside the fuel tank, with a length direction of the muffler disposed along a longitudinal direction of the vehicle body; a first exhaust pipe that connects an exhaust port of the engine to the muffler; and a second exhaust pipe connected to the muffler, and comprising a free end through which exhaust gas is exhausted. The number of mufflers is exactly one.

Abstract: A fixing device for an automobile muffler is constructed to effectively support and minimize the vertical and transverse movement of a muffler in relation to a car body via a resilient hanger that is diagonally angled. The rear part of the resilient hanger is attached with a cover bracket and a body side bracket, wherein the cover bracket is formed with a vertical flange surface and the body side bracket is formed with a vertical protrusion surface, thereby effectively support any longitudinal movement of the muffler against the vehicle, and increasing the rigidity of connecting parts between the muffler and an exhaust pipe via the cover bracket.

Abstract: A noise control type intake hose adapted to improve a noise reducing function to increase the productivity and minimize space in the intake system. The noise control type intake hose comprises an intake hose, a hose expanding part formed at a certain portion of the intake hose, an inner cover formed inside the hose expanding part, a wall formed for obtaining a sealed area between the hose expanding part and the inner cover, and an inner hose protruding out from the inner cover to interconnect the inner side of the intake hose and the sealed area.
