Abstract: To further reduce manufacturing steps and improve display characteristics. A display device includes: a light emitting element; a first capacitor including a first electrode and a second electrode; a second capacitor including a third electrode and a fourth electrode; and a drive transistor that supplies, to the light emitting element, a current corresponding to a voltage accumulated in the first capacitor and a voltage accumulated in the second capacitor, in which the second electrode is electrically connected to the third electrode, and the second electrode and the third electrode are disposed in different layers.

Abstract: A partition plate for multiple-stage adsorption separator includes a planar body member having opposing external surfaces and a peripheral edge with conduits providing fluid communication between the opposing surfaces and different points on the peripheral edge. Each of the opposing surfaces is provided with a peripheral rim and covered with a perforated plate whereby an open chamber is defined between the body member and a perforated plate at each of the external faces.

Abstract: An adsorbent is charged into a horizontal type packed column having a multiplicity of packed vessels each of which is composed of a partition plate and a cylindrical body and which are connected through the partition plates, from an opening formed on the upper wall of each cylindrical body. Then, each opening is closed tightly with a detachable plug cover. The partition plate is provided with a first fluid passage through which a fluid is passed in the direction of the axis of the cylindrical body and a second fluid passage which is in communication with the first fluid passage, which extends toward the peripheral wall of the cylindrical body and which opens at the cylindrical body. This apparatus is suitable for use as a multiple-stage adsorption separator directed to a simulated moving-bed system.
