Abstract: 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.

Abstract: The present invention forms screw-like projection at the entrance of ceramic bottle and enables air-tightening with plastic cork, formed with screw-like projection in its body. It guarantees air tightening of ceramic bottle, and does not use imported cork, which decreases the need to import. Moreover, increases productivity by automating the air-tightening process of plastic cork. The present invention can reduce cost of production, at the same time, increasing productivity, and it can be re-used multiple times after the air-tightening.

Abstract: 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.

Abstract: In method for freeze-crushing waste resources, freezing gas is first created by collecting freezing heat source of liquefied petroleum gas during a heat exchange process between the liquefied petroleum gas and cooling gas, and then the waste resources stored in a freezing tank is frozen to a temperature where the waste resources can be easily crushed by supplying the freezing gas to the freezing tank. Next, the frozen waste resources is crushed in an crushing apparatus, after which the freezing gas is separated from the crushed waste resources in a separate apparatus and the freezing gas for is collected the purpose of reuse.

Abstract: Disclosed is a DPLL circuit including a PCR register receiving and storing PCR values; an LPCR counter counted by a system clock; an LPCR register fetching an LPCR value every PCR input cycle; a phase error detector determining a difference in values stored in the PCR and LPCR registers, and calculating a present phase error requiring compensation; an interpolator interpolating signals between phase error values; a gain calculator determining a difference between consecutive LPCR values, then calculating a gain value, a D/A converting portion multiplying values output from the interpolator and the gain calculator, then converting the resulting signals into analog signals; and a VCO generating system clock frequencies according to signal voltage output from the D/A converting portion. In another aspect, the DPLL circuit is used in MPEG2 systems.
