Abstract: One embodiment discloses a DC-DC converter which, in a solar-related energy storage system, cuts-off the over-discharging of a battery, and a control method thereof. Specifically, disclosed are a DC-DC converter which protects a battery by appropriately switching between a sleep mode which minimizes battery consumption by maintaining only minimized functions and a cut-off mode which prevents the battery from over-discharging by physically cutting off a circuit connected to the battery, and a control method thereof. Also, an embodiment discloses a DC-DC converter or reverse wiring protection device for between a solar panel and a battery.

Abstract: An image sensor including a substrate having first and second surfaces that are opposite to each other. The substrate includes unit pixel regions having photoelectric conversion regions. A semiconductor pattern is disposed in a first trench defined in the substrate and defines the unit pixel regions. The semiconductor pattern includes a first semiconductor pattern and a second semiconductor pattern disposed on the first semiconductor pattern. A back-side insulating layer covers the second surface of the substrate. The first semiconductor pattern includes a side portion extended along an inner side surface of the first trench and a bottom portion connected to the side portion and disposed closer to the second surface of the substrate than the side portion. The second semiconductor pattern extends toward the second surface of the substrate and is spaced apart from the back-side insulating layer with the bottom portion of the first semiconductor pattern interposed therebetween.

Abstract: The present invention provides a glass wool cutting device. The device includes a cutting section housing that has a cutting section chamber, a feed port that is connected to the cutting section chamber, and a discharge port that is connected to the cutting section chamber. A stationary knife is disposed on the cutting section housing to protrude into the cutting section chamber and a movable cutter that has a rotary support body is disposed in the cutting section chamber and a movable knife is supported on the rotary support body to apply a shearing force to the glass wool together with the stationary knife. Additionally, a cutter actuator provides a driving force to the rotary support body.

Abstract: Provided is a bushing for manufacturing a three-dimensional composite preform using a tow made of a fiber reinforced polymer. The bushing includes a base plate in which one or more through-holes are formed, and a plurality of spools spaced apart from each other on the base plate. A flat top is formed at an end portion of the spools, and grooves are formed on outer surfaces of the plurality of spools in a circumferential direction thereof.
