20140033832 | PRESSING ROLLER TESTING APPARATUS FOR PRINTER - A pressing roller testing apparatus for a printer includes a base, a duplexer module positioned on the base, and a resisting module fixed on the base. A paper pressing roller is fixed on the duplexer module. The resisting module includes a rotating axis, a rotating wheel mounted on the rotating axis, a pressure detecting unit mounted on the rotating wheel, a supporting block mounted on the rotating wheel, and a resisting block connected to the pressure detecting unit and the supporting block. A top surface of the resisting block contacts the paper pressing roller. A bottom surface of the resisting block contacts the pressure detecting unit. The rotating axis is rotated and the resisting block resists against the paper pressing roller. The paper pressing roller generates an elastic counterforce on the pressure detecting unit by the resisting block. The pressure detecting unit detects and output value of the counterforce. | 02-06-2014 |

20120268188 | VOLATGE LEVEL SHIFTING APPARATUS - A voltage level shifting apparatus is disclosed. The voltage level shifting apparatus has a cross-coupled transistor pair, a plurality of transistor pairs, a first diode string, a second diode string and an input transistor pair. One of the transistor pairs is coupled to the cross-coupled transistor pair, and the transistor pairs are controlled by a plurality of reference voltages. The first and the second diode strings are coupled between two of the transistor pairs. Each of the first and the second diode strings has at least one diode. The input transistor pair receives a first and a second input voltage, and the first and second input voltages are complementary signals. The cross-coupled transistor pair generates and outputs a first output voltage and a second output voltage by shifting the voltage level of the first and the second input voltage. | 10-25-2012 |
