摘要:
Disclosed is a luminance-enhanced film, including birefringent island-in-the-sea yarns, whose island portions are grouped, based on two or more spinning cores, present in a sheet. The luminance-enhanced film causes formation of an optical modulation interface between island portions and sea portions, thus maximizing optical modulation efficiency, as compared to conventional birefringent island-in-the-sea yarns. The birefringent island-in-the-sea yarns of the present invention are free of aggregation of island portions in the center thereof, although the number of island portions is 500 or more. As a result, the birefringent island-in-the-sea yarns maximize an optical modulation interface area, and thus considerably improve optical modulation efficiency, as compared to conventional birefringent island-in-the-sea yarns including one spinning core. Accordingly, the birefringent island-in-the-sea yarns advantageously exhibit considerably improved luminance, as compared to conventional birefringent island-in-the-sea yarns wherein birefringent fibers or one spinning core is present in a sheet.

There is provided an online broadcasting system for providing virtual co-presence to broadcast audiences. The online broadcasting system may comprise a plurality of user terminals, a user reaction processing server and a broadcast server configured to transmit broadcast program data to the user terminals. The user terminals may be configured to: display a broadcast program based on the broadcast program data; receive individual user reaction data from a user input interface; and transmit the received individual user reaction data to the broadcast server. The user reaction processing server may be configured to: receive the individual user reaction data from each of the user terminals; aggregate the individual user reaction data to create total user reaction data based on the received individual user reaction data; generate interface control data based on the total user reaction data, wherein the interface control data, when executed, is operative to cause a client application to generate output indicative of the total user reaction data; and transmit the generated interface control data to at least one of the user terminals.

Mask ROM cell and method of fabricating the same, is disclosed, including a semiconductor substrate of a first conductivity type, a plurality of impurity diffusion regions of a second conductivity type, formed in the semiconductor substrate in one direction, having a predetermined distance therebetween, an insulating layer formed on a portion of the semiconductor substrate, corresponding to each impurity diffusion region, a gate insulating layer formed on the semiconductor substrate, and a plurality of conductive lines formed on the gate insulating layer and insulating layer in a predetermined interval, being perpendicular to the impurity diffusion regions.
摘要:
A process for producing a photoresist pattern is disclosed. In particular, the disclosed process for forming a photoresist pattern reduces or prevents poor quality photoresist patterns formation, especially when a high light absorbing (i.e., low transmittance) photoresist resin is used. In one aspect, a photoresist film which has been exposed to light is treated with a gas phase basic compound to produce a substantially vertical photoresist pattern.
摘要:
The present invention provides photoresist resins and photoresist compositions comprising the same, which are useful in a resist flow process. The present invention also provides a process for forming a contact hole pattern using the same. In particular, the photoresist resin of the present invention comprises a mixture of polymers. Preferably, a mixture of a first copolymer and a second copolymer. In one aspect, the first and the second copolymers have different properties. Photoresist compositions of the present invention can be used to reduce or eliminate photoresist overflow during a resist flow process. In addition, photoresist compositions of the present invention allow formation of uniform sized patterns and improve standing wave effect.

The present invention provides a triple-effect absorption chiller with vapor compression units, where one or more vapor compressors are connected to GM, GH, or evaporator of a conventional chiller, to compress refrigerant vapor from the said generators or evaporator, thereby lowering the GH temperature to a preferable range of below 170° C. The triple-effect absorption chiller of the present invention can be practically applied for lowering the temperature of GH, without the corrosion due to the high temperature of GH.
摘要:
A tablet dropping unit for an automatic tablet dispensing system is disclosed, and an automatic tablet dispensing system which incorporating the tablet dropping unit is disclosed. The automatic tablet dispensing system includes a drum unit communicating with a plurality of release holes which fixate a plurality of tablet cassettes, storing therein and releasing therefrom, a measured quantity of tablets. Tablet released from the tablet cassettes drop via release holes to a guide hopper of a tablet packaging unit. The packing unit packages the tablets released from the tablet dropping unit and discharges the packaged tablet bags to an exterior of the automatic tablet dispensing system. The drum unit has a pair of arc-shaped drum bodies partitioned by a predetermined space therebetween. An auxiliary arc-shaped drum is further located within each of the arc-shaped drum bodies.
摘要:
A tablet cassette for an automatic tablet dispensing system is disclosed. The tablet cassette includes a cylindrical rotor received into a medicine case of the tablet cassette and engaged to a male gear fixed to a motor shaft located within a driving unit. The rotor has a waved guide formed along an conically tapered upper surface thereof and a protrusion formed on a central surface portion thereof so as to smoothly agitate the received tablets and preventing from tangling together with said waved guide. The cylindrical rotor has a plurality of guide teeth formed along an outer periphery of the rotor body and a plurality of insert openings regularly provided between said guide teeth to respectively receive one tablet therein. At least one auxiliary case has an upper and a lower engagement steps formed along the periphery thereof. The upper engagement step has thrust bumps along an upper periphery thereof to facilitate engagement onto an upper portion of the medicine case having a corresponding engagement step formed along an upper periphery thereof, and the lower engagement step of the said auxiliary case has thrust grooves formed in correspondence to the thrust bumps of the medicine case. A cover is provided onto an upper portion of the medicine case or said auxiliary case. The cover includes a porous compartment formed underneath a lower surface thereof, wherein preservatives or demoisturants can be placed.
