Abstract: An apparatus for growing an ingot from a melt accommodated in a crucible of a chamber comprises a first senor and a controller. The first sensor is installed on one side of the chamber for detecting a detection signal in real time from a side portion of the ingot. The side portion of the ingot rotates via a detection area focused by the first sensor. The controller obtains a detection signal at each of a plurality of sampling points based on detection signals detected in real time, obtains a value of a central point of the ingot based on the detection signal at each of the plurality of sampling points, and determines whether or not the ingot is defective based on the value of the central point of the ingot.

Abstract: Disclosed are a rubber composition for a motor mount that exhibits improved fatigue resistance and maintains desired mechanical properties using a second crosslinking agent having a first functional group and a second functional group different from each other, and a rubber for motor mounts including the same. The rubber composition includes a natural rubber, a filler, an activating agent, an antiaging agent, a dispersant, a first crosslinking agent containing sulfur, a vulcanization accelerator, and a second crosslinking agent having different first functional groups and second functional groups, wherein the first functional group is N-hydroxysuccinimide ester (NHS ester), and wherein the second functional group is maleimide.

Abstract: Disclosed are a rubber composition for a dynamic damper and a dynamic damper including the same. The rubber composition may include a resin including ethylene-propylene-based rubber and halogenated isobutylene-isoprene rubber, a filler, a plasticizer, a crosslinking agent and a vulcanizing accelerator. For example, the rubber composition may be prepared by mixing the resin including the ethylene-propylene-based rubber and the halogenated isobutylene-isoprene rubber, the filler, the plasticizer, the crosslinking agent and the vulcanizing accelerator at an optimal mixing ratio, thus increasing the loss factor thereof while decreasing the temperature dependency thereof across the broad range of temperatures to thereby improve anti-vibration characteristics regardless of changes in season or temperature.

Abstract: A thermoplastic elastomer composition, and more particularly, a thermoplastic elastomer composition for use in manufacturing a joint connecting a glass run and an inner-belt. The thermoplastic elastomer composition includes an ethylene propylene diene monomer (EPDM), polybutene (PB), polypropylene (PP), paraffin oil, a peroxide cross-linking agent, and an antioxidant.
