Abstract: In order to provide a fluid heating device for battery heating of an electric vehicle to ensure durability of a heating device and prevent malfunction of the device due to submersion, a fluid heating device for battery heating of an electric vehicle of the present disclosure includes a housing configured to allow fluid to flow in and out and form a first space in which the fluid is heated, and a heater configured to form a path through which the fluid flows into the first space and heat the fluid.

Abstract: The present disclosure provides a smoking article filter which includes lyocell tow including lyocell fibers, a binder solution, and filter wrapping paper, and has 90% or higher biodegradation within 6 months according to the American Society for Testing and Materials (ASTM) D6691 under marine conditions at 30° C., and a smoking article including the smoking article filter.

Abstract: A cigarette filter which includes lyocell tow made of a plurality of lyocell fibers and a binder configured to bond the lyocell fibers to each other is provided. The cigarette filter according to one embodiment of the present disclosure reduces each of tar and nicotine, which are delivered through cigarette smoke, by 70% to 95%. The cigarette filter according to one embodiment of the present disclosure has a resistance to draw of 80 mmWG to 200 mmWG. The cigarette filter according to one embodiment of the present disclosure is filled with the lyocell tow at a packing density of 0.2 g/mL to 0.6 g/mL. The cigarette filter according to one embodiment of the present disclosure addresses basic material-related problems, such as low hardness, of the lyocell tow and, further, has excellent filtration functionality as a filter.

Abstract: A display device including: scan lines including first and second scan lines; pixels connected to the scan lines; photo sensors connected to some of the scan lines, the photo sensors including a first photo sensor connected to the first scan line and a readout line, and a second photo sensor connected to the second scan line and the readout line; a scan driver to provide scan signals to the scan lines; and a readout circuit to receive, through the readout line, detection signals which are outputted from the photo sensors in response to the scan signals, wherein, while the scan signals are provided to the first and second scan lines, the readout circuit samples a detection signal of one of the first photo sensor and the second photo sensor without sampling a detection signal of the other one of the first photo sensor and the second photo sensor.

Abstract: A source driver and a display device including the same includes a latch unit to store data, a digital-to-analog conversion (DAC) unit to convert the stored data into an analog signal, amplifiers to amplify or buffer the analog signal, output pads, output switches between the DAC unit and the output pads corresponding to the amplifiers, and an output controller to generate switch control signals that control the output switches based on/in response to a source output enable signal. The amplifiers and the output switches include a plurality of groups. The switch control signals to the output switches of each group may have different delay times based on the source output enable signal. Delay times between contiguous switch control signals to at least one group may be different from delay times between contiguous switch control signals to one or more other groups.

Abstract: A magnetron includes a yoke, an anode unit including an anode cylinder, radially arranged vanes, and first and second pole pieces at both sides of the anode cylinder, a cathode unit having a filament spaced apart from the vanes, and an output unit having an antenna lead connected to one vane to radiate high-frequency microwaves. The first pole piece includes a first flat portion, a slope at an inner side of the first flat portion, a second flat portion at an inner side of the slope and having a diameter of 9.5˜10.5 mm, a first hole formed in the second flat portion and having a diameter of 8˜8.2 mm, and a second hole formed in the slope for penetration of the antenna lead. The magnetron achieves higher and stabilized efficiency, restricted oscillation efficiency variation, lower energy consumption, and improved load stability without deterioration of oscillation efficiency.
