  • Patent number: 10186712
    Abstract: Provided is a catalyst for an oxygen reduction reaction, including an alloy in which two metals are mixed, in which the corresponding alloy is an alloy of iridium (Ir); and silicon (Si), phosphorus (P), germanium (Ge), or arsenic (As). The corresponding catalyst for the oxygen reduction reaction may have excellent price competitiveness while exhibiting a catalytic activity which is equal to or similar to that of an existing Pt catalyst. Accordingly, when the catalyst is used, the amount of platinum catalyst having low price competitiveness may be reduced, so that a production unit cost of a system to which the corresponding catalyst is applied may be lowered.

  • Publication number: 20080011525
    Abstract: The present invention relates to a design of a driving mechanism for a vehicle to move through uneven terrain including stairways. The link-type double track mechanism in accordance with the present invention comprises: front and rear track driving sections; a built-in type control box; a set of angle-adjusting flippers, installed at front and rear ends of the control box, for adjusting the track angle; and high-speed driving wheels installed at the angle-adjusting tracks and imbedded inside. The link-type double track mechanism in accordance with the present invention does not require a complex terrain-adaptation mechanism, and thus it has advantages that the overall structure is simple and the control is very easy.

  • Publication number: 20020075533
    Abstract: In order to have a wanted exposure pattern, a specific intensity of light should be irradiated for a certain time interval since the exposing degree of the photoresist depends on the intensity of the incident light. The intensity of the light emitted from a light source such as a conventional laser has the Gaussian distribution in space, and the Gaussian distribution is maintained after passing a conventional lens. And the uniform area is limited to a very narrow area since the exposure pattern is changed with the intensity distribution of the light incident to the photoresist.
