Abstract: A wafer cleaning apparatus provided by the present invention comprises a rotary shaft, a chuck arranged on the top of the rotary shaft for retaining the wafer, a fixed shaft coaxially passed through the rotary shaft, and an upper end cover and a lower end cover that block the top and bottom of the fixed shaft respectively. Wherein, the fixed shaft is a hollow shaft with at least one circle of exhaust holes provided on the wall of the fixed shaft. The lower end cover is arranged with a gas inlet port, through which a protective gas is provided to the interior of the fixed shaft. The protective gas forms a positive pressure in the annular space between the fixed shaft and the rotary shaft through the at least one circle of exhaust holes. The present invention provides positive pressure protective gas to the spacing between the fixed shaft and the rotary shaft by opening exhaust holes on the wall of the fixed shaft.

Abstract: A novel mobile terminal is provided. The mobile terminal includes a display screen element, a battery element, and a machine chip element separately disposed. Because the main functional components in the mobile terminal, such as the display screen element, the battery element, and the machine chip, are arranged separately, a shape of the display screen is no longer restricted by the shape of the functional components, such as the battery and the chip, and can be set to any shapes. Thus, a flexible screen can be bent arbitrarily, and the problems that the flexible display screen disposed in the conventional mobile terminal is subject to the shape of functional components and cannot be bent arbitrarily are solved.

Abstract: An article for holding foodstuff. The article comprises a receptacle (4) having a wall with an inner surface for holding the foodstuff and an opposite outer surface. The wall is formed of a first material, such as a ceramic material, having a first thermal conductivity. The articles also has a shell (1; 5) spaced apart from the outer surface of the receptacle such as to define an interstitial chamber (2, 3) between the shell and the outer surface of the receptacle. The shell is at least partially formed of a ceramic material with a second thermal conductivity. Within the interstitial chamber, there is disposed a phase change material which abuts with at least the outer surface of the wall of the receptacle. The first thermal conductivity being greater than the second thermal conductivity, so as to allow for heat transfer through the wall to the phase change material, which will accumulate the heat.
