摘要:
The present invention relates to a lens driving device includes a lens receiving part with a lens disposed therein, having first and second extension parts formed at opposed sides in a predetermined interval from each other. The lens driving device also includes an actuator having a body between the first and second extension parts. The actuator body has first and second output members contacting the first and second extension parts of the lens receiving part at opposed ends thereof, and thereby expands, contracts and bends when power is applied. The lens driving device also includes a preload member compressing the first and second extension parts against the actuator body to maintain a status of pressed contact. The lens driving device further includes a guide part for guiding the movement of the lens receiving part in an optical axis direction.

A point-of-sale electronic distribution system for distributing an access code (e.g., a personal identification number (PIN)) is provided. The system allows retailers/distributors to purchase access codes for use with pre-paid products using conventional telephones and without requiring the use of a dedicated terminal or personal computer at the point-of-sale. A telephone call relating to a request for an access code is received at a central server. An access code is obtained from a database of access codes and transmitted to the caller by telephone, facsimile, or e-mail. Reports relating to a pre-paid calling card account can be requested during the telephone call.

Provided is a method of fabricating an organic field effect transistor (OFET). The method includes: forming an OFET pattern on a substrate, the OFET pattern having a gate electrode, a dielectric layer, a source electrode, a drain electrode, and an organic semiconductor layer; attaching a junction layer covered with a predetermined adhesive on the entire surface of the source and drain electrodes and the organic semiconductor layer and isolating the OFET pattern from the substrate; and transferring the isolated OFET pattern onto a plastic substrate that is prepared beforehand. In this method, the OFET pattern can be deposited without the temperature limit, the dielectric layer can be formed using a wide variety of materials, and the OFET pattern can be transferred in a very simple manner. Also, the junction layer functions as a passivation layer for protecting the organic semiconductor layer from external air and moisture so that the organic semiconductor layer can keep good performance for a long time.

A programmable logic array (PLA) in accordance with the invention achieves a maximum amount of depopulation of programmable connections while still implementing a logic function and maintaining flexibility for future reprogramming. In addition, a PLA in accordance with the invention can be built so that no matter what functionality is programmed, performance characteristics for the device are maintained. Further, a PLA in accordance with the invention does not require a regular array structure.

An eyeglass frame assembly for coupling clip-on auxiliary spectacles to primary spectacles. The primary spectacles having a pair of cavities formed on one of the frame and the inside surface of rear extensions. The clip-on spectacles having a pair of insertable members mounted on a pair of hinged extensions, wherein the insertable members are capable of positively engaging the cavities. The hinged extensions allow the clip-on spectacles to swing up and to place the auxiliary lenses mounted within the clip-on spectacles to be outside the vision path of the user.
