An electronic device according to various embodiments of the present invention may comprise: a body portion comprising a first surface facing in a first direction, a second surface facing in a second direction that is opposite to the first direction, and a seating groove arranged in an inner peripheral area thereof in the longitudinal direction; a display portion rotatably coupled to the body portion; and a connector module arranged in the seating groove of the body portion so as to provide electric coupling between the body portion and the display portion, at least a part of the connector module being configured to rotate. The connector module may comprise: a support portion fixed/coupled inside the seating groove, the support portion comprising an opening arranged therein; a link portion rotatably coupled to the support portion, the center area of the link portion being open so as to correspond to the opening of the support portion; at least one elastic member arranged between the support portion and the link portion so as to provide elastic restoration power caused by rotation of the link portion; and at least one cable connected from the body portion to the display portion through the opening of the link portion, the cable being folded or unfolded by rotation of the link portion.

A method for manufacturing an alloy catalyst for a fuel cell is disclosed. The method for manufacturing an alloy catalyst for a fuel cell may include predetermined processes and reaction conditions, such that iridium is alloyed to platinum contained in a cathode carbon support catalyst. Accordingly, time for stabilizing charge on the carbon surface may be reduced and a metal particle size may be controlled, thereby manufacturing high quality products having uniform metal particle distribution and improved durability. In addition, corrosion of a cathode carbon support catalyst in a harsh condition such as vehicle driving may be prevented.

A method and system for fracturing or mask data preparation is disclosed in which the central core portion of a diagonal pattern is fractured using overlapping variable shaped beam (VSB) shots, and an outer portion of the diagonal pattern is fractured using non-overlapping VSB shots. A transition region is interposed between the central core and outer pattern portions, and transition region shots are generated so as to produce in the transferred pattern a smooth transition in pattern characteristics such as line edge roughness or period of waviness, from the central core portion of the pattern to the outer portion of the pattern. A pattern determined by the transition region shots is then compared to a reticle pattern created using conventional non-overlapping VSB shots. Methods for forming a semiconductor device layout pattern on a reticle or substrate are also disclosed.
