Abstract:
An ultrasonic probe and a manufacturing method thereof are provided. The ultrasonic probe improves performance by separating first tiles, which transmits ultrasonic beams, and second tiles, which receive the ultrasonic beams, from each other. The ultrasonic probe comprises: the n number of the first tiles which transmit ultrasonic beams to an object; and the m number of the second tiles which receive the ultrasonic beams fed back from the object.
Abstract:
An apparatus and a method for maintaining the freshness of foods are provided to perform electric field application and temperature control through single electrode without separate temperature control by connecting a heat transmission part to the electrode for voltage application. An apparatus and a method for maintaining the freshness of foods comprises first and second electrodes(1,2), a voltage generating part(3), a heat transmission unit(4) and a temperature controller(6). The first and the second electrodes are apart from each other at fixed intervals which are set up in advance. A voltage generating part applies the voltage between the first and the second electrodes. The heat transmission unit is connected to the first or the second electrode and absorbs heat from a space between the first and the second electrodes. The temperature controller controls the heat transmission unit to adjust the temperature in the space between the first and the second electrodes to be the temperature which is set up in advance.
