Abstract: A multilayer capacitor includes a body including dielectric layers and internal electrodes and external electrodes disposed on an external surface of the body and connected to the internal electrodes. The body includes a first surface and a second surface to which the internal electrodes are exposed, the first surface and the second surface opposing each other in a first direction, a third surface and a fourth surface opposing each other in a second direction which is a direction in which the dielectric layers are stacked, and a fifth surface and a sixth surface opposing each other in a third direction. At least one of the internal electrodes include a first bottleneck structure having a first directional length of a third-directional outer region smaller than an inner region thereof and a second bottleneck structure having a third directional length of a first directional outer region smaller than an inner region thereof.

Abstract: A variable exhaust valve assembly for a vehicle includes an exhaust housing, a power transmission device that transmits rotational power, a shaft that extends through the exhaust housing and is coupled with a valve so as to open and close the exhaust housing, and a heat shielding unit to reduce heat transfer between the power transmission device and the exhaust housing. The power transmission device is configured to regulate an opening degree of the valve. The variable exhaust valve assembly is improved in durability by minimizing damage to power transmission caused by high-temperature heat of exhaust gas, and reducing vibration transmitted to the power transmission device.

Abstract: An electric valve may include a valve housing, a valve plate disposed in the exhaust gas passage of the valve housing by a rotation shaft, a heat shield being connected to the valve housing by a bracket and forming a penetration opening to be penetrated by an upper end portion of the rotation shaft, an actuator assembled on the heat shield to decelerate torque of a drive actuator and then to output the decelerated torque, a power delivering member transferring torque of the drive actuator, wherein damping is performed by a power delivering spring disposed between a spring seat mounted the rotation shaft and the worm wheel of the actuator, to the rotation shaft, and a rotation limiting member mounted between the penetration opening of the heat shield and the spring seat corresponding with the penetration opening to limit a rotation angle of the rotation shaft.
