A connector is provided for preventing a connection terminal inserted into a connector housing from being dislodged. This organic EL light emitting element has a transparent conductive layer, organic light emitting unit layer, and metal layer in that order on a transparent substrate. A tunneling oxide layer is provided on the surface of the semiconductor substrate. Also provided are methods for increasing oil yield, comprising genetically modifying a plant to cause, in at least one oil-producing organ or tissue of the plant, a decrease in triose-phosphate isomerase activity and an increase in glycerol-3-phosphate dehydrogenase activity. To increase the range of motor vehicles that have at least one electric drive device, an internal combustion engine is arranged in the climate control box. The host computer is operationally coupled to the port to participate in the communication by generating the data signals.
