Abstract: An ultrasonic transducer employing a meta slab includes a piezoelectric body configured to generate elastic waves; a meta slab connected to the piezoelectric body and configured to induce elastic wave mode conversion resonance with respect to the elastic waves incident on the meta slab; and a wedge connected to the meta slab, attached to an external surface of a pipe, and configured to transmit the elastic waves having passed through the meta slab to the pipe. The meta slab includes an anisotropic medium and a thickness of the meta slab satisfies the equation as follows: d=m·nFS·?FS/4, d=m·nSS·?SS/4, nSS/2?nFS/2=odd. Thus, highly-efficient flow velocity measurement is possible.

Abstract: A water pocket with an open top side is filled with water, mounted in a regular position on a supporting frame, and tilts to supply the water stored in the water pocket to an ice making tray, thereby easily supplying a required amount of water to the ice making tray. A refrigerator includes an ice making tray provided to linearly move with rotation when ice of the ice making tray is separated, or includes a holding preventing member which prevents the ice from being caught by a lower ice making tray, thereby improving a forward-and-backward width of an ice maker. It is possible to easily withdraw ice stored in an ice bucket by pushing an ice discharge button in a state in which the ice bucket is not separated.
