摘要： A level shifter capable of high speed operation and a high-speed level shifting method. The level shifter includes a pull-down switching unit configured to selectively connect a first node and a second node with a first power supply (ground) voltage in response to a first switching signal and a (complementary) second switching signal, a pull-up switching unit connected between the first node and the second node and configured to connect the first node with a second power supply voltage in response to the voltage level of the second node and to connect the second node with the second power supply voltage in response to the voltage level of the first node, and a internodal switch configured to selectively connect the first node with the second node in response to a control signal. Due to the switching operation and resistance of the internodal switch, the level shifter can reduce power consumption and perform high speed level-shifting operation.

摘要： A container is specially configured to enable a user to withdraw stored fasteners such as nails, screws, bolts, and the like. The device includes a receptacle base having a bottom wall and a continuous side wall that can be somewhat squared in shape. The receptacle base could be cylindrically shaped, oval shaped, or any other selected shape in plan view. A lid removably attaches to the side wall at the wall upper edge, the lid including a lid front section and a lid rear section. A hinge enables the front lid section to rotate about a hinge axis of rotation between closed an open positions. Each lid section has a raised portion that includes a plurality of inclined surfaces that define frictionally engaging correspondingly shaped socket and projecting portions that interlock when the front lid section is opened. An interference fit or frictional fit generated by the engaged socket and projecting portions holds the front lid section in the open position.
