Abstract: A drum rotating device of a laundry care apparatus includes a drum shaft coupled to a drum, and a motor including a stator and a rotor that rotates relative to the stator. A gear assembly transmits rotational force of the rotor to the drum shaft A carrier constituting the gear assembly and the drum shaft is coupled to each other in a first area. A sun gear, a ring gear (RG), and pinion gears constituting the gear assembly are engaged with each other and rotate in a second area spaced apart from the first area based on the axial direction of the drum shaft.

Abstract: A joining method between Fe-based steel and Ti/Ti-based alloys having a joint strength higher than those of base metals by using interlayers. The production of intermetallic compounds at a joint portion between Fe-based steel and Ti/Ti-based alloys can be prevented using interlayers, and strong interface diffusion bonding can be formed at interfaces between interlayers, thereby producing a high-strength joint. Accordingly, the present disclosure can be used to develop high-strength, high-functional advanced composite materials.

Abstract: A method of forming an isolation layer of a semiconductor device includes forming first trenches in an isolation region of a semiconductor substrate. Sidewalls and a bottom surface of each of the first trenches are oxidized by a radical oxidization process to form a first oxide layer. An oxidization-prevention spacer is formed on the sidewalls of each of the first trenches. Second trenches are formed in the isolation region below the corresponding first trenches, wherein each second trench is narrower and deeper than the corresponding first trench. The second trenches are filled with a second oxide layer. The first trenches are filled with an insulating layer.

Abstract: An alarm suppressing method for an optical transmission apparatus includes the steps of checking whether a detected alarm is a root alarm, suppressing a first propagation alarm generated by the root alarm when the detected alarm is a root alarm, determining the types of network elements, suppressing a second propagation alarm generated by the root alarm in accordance with the determined types of the network elements, and suppressing a third propagation alarm generated in accordance with the second propagation alarm. The method further includes the steps of recognizing the direction of a detected propagation alarm, retrieving an element next to the recognized direction, checking the kind of the generated propagation alarm, and suppressing a corresponding propagation alarm when a data base includes a root alarm by retrieving from the data base the information relevant to the root alarm in accordance with the kinds of the checked alarms.
