There is provided a dust compressing apparatus for a dust collecting unit of a vacuum cleaner. In the dust compressing apparatus, a compartment plate divides an inner space of a dust collection container into an upper foreign substance separating compartment and a lower foreign substance storing compartment, and a branching unit guides airflow. The branching unit includes a motor connection passage directed to a motor generating a negative pressure, a dust collection passage directed to the foreign substance separating compartment, and a compression passage directed to the foreign substance storing compartment. A flow passage control unit controls connections between the passages of the branching unit. A compression unit compresses foreign substances stored in the foreign substance storing compartment by moving the compartment plate to the foreign substance storing compartment using the negative pressure transmitted through the compression passage.

An organic electroluminescent (EL) device is provided which uses an electron-transport layer including hole blocking capability. The device includes a stack structure, with an emitting layer and an electron-transport layer provided between an anode and a cathode. The electron-transport layer is a mixture of at least two materials. This mixture may include an organic compound and one or more other organic compounds, or may include a metal or inorganic compound and one or more other metal or inorganic compounds, or may include one or more organic compounds and one or more metal or inorganic compounds. By incorporating a hole blocking capability into the electron-transport layer, structure and fabrication of the device is simplified and efficiency is increased.
