In one aspect, the invention provides a catalyst for converting diesel type liquid hydrocarbons to methane rich gas. A plurality of planet gears are rotatably mounted to the planet carrier. The data records in the dataset are read directly from the database for each iteration, and the data model is trained inside the database by repeatedly applying the read data records in the training operation and updating the data model. A predetermined stick voltage is applied to a plurality of electrodes formed on a substrate of an electronic device forming the organic thin film using a circuit previously formed on the substrate and thus the organic material pseudo-molecular ion is selectively stuck to a predetermined electrode. The support electrode is laid out around the lower electrodes while being insulated and isolated from the lower electrodes, and formed to be higher than the lower electrodes to support the upper electrode.
