20120063260 | TURBINE VIBRATOR - A turbine vibrator has a housing, an eccentric rotor mounted in an air chamber of the housing and two covers mounted respectively in two mounting recesses of the housing. Two threaded walls defined respectively around the mounting recesses of the housing have same threaded directions. Therefore, the mounting recesses, the air chamber and the other mounting recess are formed sequentially so axes of the mounting recesses and the air chamber are disposed along a same line. Manufacturing processes of the housing is reduced and shearing forces applied to the shafts of the eccentric rotor are reduced so the turbine vibrator has a prolonged useful life. Moreover, as a rotating direction of the eccentric rotor and the fastening directions of the covers are the same, when the turbine vibrator operates, the covers tighten against the housing. The first and second covers do not drop from the housing. | 03-15-2012 |

20140075491 | ERROR PROOF METHOD FOR RECORDING AND RECORDING DEVICE - The method is applied to the recording device, and the recording device is connected to a set-top box. The error proof method includes following steps. In the beginning, whether a startup process of the set-top box has been finished is determined according to a video signal and an audio signal outputted from the set-top box. After the startup process of the set-top box is finished, the video signal outputted from the set-top box is analyzed to determine whether an image of the video signal is covered by an information window. If the image of the video signal is not covered by any information window, then a channel changing signal is transmitted to the set-top box, to change a channel of the set-top box to a reserved recording channel. After that, a television program of the reserved recording channel is recorded. | 03-13-2014 |
