摘要:
A multi-transmission phase mask, and a method of manufacturing a multi-transmission phase mask are disclosed. The method comprises the steps of primarily patterning a light shielding layer after forming the light shielding layer on a light transmissive substrate, forming a plurality of pattern regions of a semiconductor by etching the light transmissive substrate to a predetermined depth using the primarily patterned light shielding layer, and secondarily patterning the light shielding layer and forming a phase shift region between the adjacent pattern regions of the semiconductor such that a predetermined portion of a surface of the light transmissive substrate is exposed to the outside between the adjacent pattern regions of the semiconductor. Each of the pattern regions provides a phase delay of 180° while a gap between the pattern regions provides a phase delay of 0°, thereby realizing a minute pattern and a critical dimension of the pattern with high precision.

A method of producing a polyethylene terephthalate-based polyester fiber includes spinning polyethylene terephthalate based polyester to produce an undrawn yarn with an intrinsic viscosity of 0.83 or more and a density of 1338 g/cm3 or more, multi-stage drawing the undrawn yarn, heat-setting the drawn yarn, relaxing heat-set yarn, and winding the relaxed yarn to produce the resulting drawn yarn with an intrinsic viscosity of 0.83 or more and a density of 1.38 to 1.3865 g/cm3, so that the thusly produced industrial polyester yarn with high modulus and low shrinkage contributes to significantly improving strength retention (tenacity of a dip cord/tenacity of a grey yarn) of the dip cord, produced by treating the polyester yarn with an adhesive (RFL) and subsequently heat-treating the RFL-treated polyester yarn, to be useful as a tire cord.

摘要:
A MAC device guarantees QoS in a VoIP wireless LAN by giving higher priority to voice data than to non-voice data. Transmission data generated by an application program is provided to a modem according to the priority assigned to the data. A kernel classifies the transmission data into voice and non-voice data. A MAC driver stores the voice and non-voice data in two queues, and transmits a MAC header to a MAC transmitter to notify it of generation of the transmission data, and transmits the stored voice or non-voice data to the MAC transmitter according to the type of a transmission interrupt received from the MAC transmitter in response to the notification. The MAC transmitter combines the voice or non-voice data, received from the MAC driver in response to the transmission interrupt, with a corresponding header, and outputs it to the modem.

An energy transfer element having an energy transfer element input winding and an energy transfer element output winding. In one aspect, the energy transfer element input winding is capacitively coupled to the energy transfer element output winding. The energy transfer element is capacitively coupled to electrical earth. One or more additional windings are introduced as part of the energy transfer element The one or more additional windings substantially reduce capacitive displacement current between the energy transfer element input winding and energy transfer element output winding by balancing the relative electrostatic fields generated between these windings and/or between the energy transfer element and electrical earth by canceling the electrostatic fields generated by all windings within the energy transfer element relative to electrical earth through the selection of the physical position and number of turns in the additional windings.
