Abstract: Provided is an oxygen reduction catalyst having a high oxygen reduction performance. An oxygen reduction catalyst according to the present embodiment includes a transition metal oxide to which an oxygen defect is introduced, and a layer that is provided on the transition metal oxide and that contains an electron conductive substance. A method for producing an oxygen reduction catalyst according to the present embodiment includes heating a transition metal carbonitride as a starting material in an oxygen-containing mixed gas. In addition, a method for producing an oxygen reduction catalyst according to the present embodiment includes heating a transition-metal phthalocyanine and a carbon fiber powder as starting materials in an oxygen-containing mixed gas.

Abstract: A display control apparatus which improves the visibility of a display unit (for example, wristwatch) having a normal display section and a normal non-display section provided outside the normal display section along its at least one side. When it is not sensed that the display unit is inclined at a predetermined angle to a horizontal surface, time information is displayed in a normal size on the normal display section. When it is sensed that the display unit is inclined at the predetermined angle to the horizontal surface, the time information is displayed in an enlarged size on a whole of the normal display and non-display sections for a predetermined time.
