Abstract: The present technology includes a power supply and a method of operating the same. The power supply includes a main power supply configured to receive external power and output a charge voltage and main power, and an auxiliary power supply including a capacitor array configured to charge auxiliary power using the charge voltage and output the auxiliary power. The auxiliary power supply is configured to periodically repeat a discharge operation and a sub charge operation on the capacitor array when the charging of the capacitor array is started.

Abstract: A vehicular air conditioning system includes: a refrigerant circulation line including first and second evaporators through which refrigerant can flow in a cooling mode, and first and second expansion valves configured to depressurize and expand the refrigerant introduced into each of the first and second evaporators; and refrigerant flow control part provided in front of the first evaporator and the first expansion valve and configured to control refrigerant flow. The first evaporator is used for cooling rear seat region of a passenger room and the refrigerant flow control part is configured to supply and block the refrigerant with respect to the first evaporator and the first expansion valve and is configured to block the refrigerant when the cooling governed by the first evaporator is controlled in a turn-off mode and supply the refrigerant to the first evaporator and the first expansion valve depending on the on/off condition of the cooling governed by the second evaporator.

Abstract: A semiconductor memory device includes a source layer, a channel structure, gate electrodes on the source layer and spaced apart on a sidewall of the channel structure, and a common source line. The gate electrodes include a first word line group including first and second gate electrodes and a second word line group including third and fourth gate electrodes. The semiconductor memory device, in response to a voltage of the common source line reaching a target voltage, causes an inhibition voltage to be applied to the second word line group and an erase voltage to be applied to the first word line group in a first erase operation interval, and causes the inhibition voltage to be applied to the first word line group and the erase voltage to be applied to the second word line group in a second erase operation interval.

Abstract: A sidestream smoke removal device and a control method thereof are provided. The sidestream smoke removal device according to some embodiments of the present disclosure may include a housing in which a smoking space is formed, an article insertion portion which is disposed at one end of the housing and forms an opening for insertion of a smoking article into the smoking space, an ignition portion which is configured to ignite the smoking article inserted into the smoking space, a sidestream smoke processing portion which is configured to process sidestream smoke generated from the smoking article inserted into the smoking space, and a heating portion disposed inside the housing to heat the smoking space. The heating portion may heat the smoking space to remove a smell generated due to by-products of smoking, and accordingly, the cleanliness of the sidestream smoke removal device can be improved.

Abstract: A chip-on-film package may include a film substrate including a chip region and an edge region, a semiconductor chip provided on the chip region and mounted on a top surface of the film substrate, the semiconductor chip including a chip pad adjacent to a bottom surface thereof, an input line and an output line provided on the edge region and disposed on the top surface of the film substrate, a connection terminal interposed between the film substrate and the semiconductor chip, and a redistribution pattern disposed between the semiconductor chip and the connection terminal.

Abstract: A connection structure of a stator of a drive motor is configured to allow coils to be wound in a plurality of slots provided in a stator core and to connect the coils withdrawn from the slots. The coils are wound in the slots to form first-type structures and second-type structures configured such that withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the first-type structures are opposite to withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the second-type structures. The first-type structures and the second-type structures are disposed symmetrically to each other with respect to a reference line formed to divide the slots in half.
