Abstract: A method of controlling a damper pulley clutch for selectively transmitting power of an engine to engine accessories, may include determining, by a controller, whether a vehicle is driven in a fuel-cut mode under deceleration of the vehicle and controlling the damper pulley clutch, by the controller, to be engaged upon determining that the vehicle is driven in the fuel-cut mode and to be disengaged upon determining that the vehicle is not driven in the fuel-cut mode.

Abstract: An engine device for a vehicle is configured such that a clutch pulley may be rotated together with a crankshaft or may not be rotated depending on the application of electric power. Therefore, when an auxiliary drive system does not need to rotate, the clutch pulley is prevented from rotating. Accordingly, torque loss attributable to dispersion of torque to the auxiliary drive system is minimized As a result, fuel efficiency is improved, and engine output is increased.

Abstract: Disclosed is an apparatus for decreasing a thrust of a radial flow turbine. The apparatus includes a rotary shaft having an axial through-hole in the interior thereof, a rotor assembled in the rotary shaft and having a rotor hub and rotor blades formed on an outer peripheral surface thereof, a casing configured to isolate the rotary shaft and the rotor from the outside, and a shaft seal configured to maintain a seal between the rotary shaft and the casing.

Abstract: A system, apparatus, and method for generating one or more path rules or combination or path rules for performing the operations of an application. According to various embodiments, a user terminal through an intelligence server may generate a path rule and may perform the operation of an application based on the path rule to provide a service. The user terminal may provide a user with the processing status of a user utterance and may receive an additional user input to process the user utterance. For example, when a keyword (or parameter) required to process the user utterance is insufficient, the user terminal may provide the user with a state requiring additional information and may output feedback corresponding to the insufficient state in order to receive the necessary information from the user.

Abstract: A ZnO-based thin film transistor (TFT) is provided herein, as is a method of manufacturing the TFT. The ZnO-based TFT has a channel layer that comprises ZnO and ZnCl, wherein the ZnCl has a higher bonding energy than ZnO with respect to plasma. The ZnCl is formed through the entire channel layer, and specifically is formed in a region near the surface of the channel layer. Since the ZnCl is strong enough not to be decomposed when exposed to plasma etching gas, an increase in the carrier concentration can be prevented. The distribution of ZnCl in the channel layer, may result from the inclusion of chlorine (Cl) in the plasma gas during the patterning of the channel layer.
