Abstract:
Provided is an unmanned mail/courier management system and method which can unmannedly receive a delivery of mail or a courier item, and can unmannedly store and receive a delivered mail or courier item. The system invention provides a configuration that enables a work, which is performed for unmanned reception and storage through interworking between an unmanned reception machine and a management server through a network in the art, to be input through and processed by a user terminal, and thus, does not require construction of a network for interworking with the management server in the unmanned reception machine for implementation thereof, thereby enabling easy installation of the unmanned reception machine, and minimizing a standby time by omitting a procedure of directly inputting in the unmanned reception machine.
Abstract:
An apparatus for preventing withdrawing and insertion of a carriage of a circuit breaker is disclosed. When a circuit breaker main body is inserted, an interlocking unit operates by interworking with the carriage withdrawing and inserting preventing apparatus, and while the circuit breaker is being closed, a withdrawal and insertion handle prevents a lead screw from being rotated by the interlocking unit. Thus, when the circuit breaker performs a closing operation, unnecessary withdrawing and inserting operation of the carriage is basically prevented to thus prevent various safety accidents, a contact resistance, a temperature increase, and damage to a device resulting from a breakdown.
Abstract:
A joint structure for fixing between a sunroof and a headliner, may include a headliner defining an opening, wherein a portion of the headliner around the opening protrudes and is curved upwards to define the opening, and the headliner has a face fabric attached to a surface thereof, a bracket attached to an upper end portion and a lower portion of the headliner, outside of the opening, wherein the bracket has a support end portion protruding in a direction opposite to the opening, a clip into which the support end portion of the bracket is selectively fitted, and a sunroof frame coupled with an upper portion of the clip, wherein the sunroof is provided on the sunroof frame.
Abstract:
Disclosed herein is a super-resolution lithography apparatus and method based on a multiple light exposure method. The super-resolution lithography apparatus comprises a photographic medium having energy levels of a first ground state, a second ground state, a first excited state, a second excited state and a quenching state; a first light source inducing energy level transition between the first ground state and the first excited state of the photographic medium; a second light source inducing energy level transition between the second ground state and the first excited state of the photographic medium; and a third light source inducing energy level transition between the second ground state and the second excited state of the photographic medium. Accordingly, the resolution of lithography can be improved simply by using a photographic medium having a simple structure and conventional laser beams and increasing the number of exposure steps. Furthermore, a multiple photon absorber that is difficult to obtain, a medium having a complicated energy level and a high-efficiency quantum optical light are unnecessary, and thus economic efficiency is improved.
