Abstract: A mode conversion apparatus includes a first freeform-surface mirror to reflect incident light provided from a front-end optical system and output the reflected light in a first direction, and a second freeform-surface mirror to reflect the reflected light and output mode-converted light in a second direction where surface shapes of the first and second mirrors are determined based on a freeform-surface coefficient determined by at least five optical parameters of a distance from the first mirror to a confocal point of the first mirror and the second mirror, a distance from the confocal point to the second mirror, a distance from a waist of the incident light to the first mirror, a distance from the second mirror to a waist of the mode-converted light, and an incident angle of the incident light for the first mirror and an incident angle of the reflected light for the second mirror.

Abstract: A drying apparatus includes an upper drying part including a first drying nozzle which is formed above an object to be dried and which extends along a width direction of the object, the upper drying part including a second drying nozzle formed on a same surface as the first drying nozzle. Furthermore, the drying apparatus includes a lower drying part including a lower drying nozzle which is formed below the object and which extends along the width direction of the object. The first and second drying nozzles are configured to dry the object with different heat sources. There is an effect that the drying deviation of the object may be minimized and the precision of the drying may be increased by effectively preventing the overdrying or non-drying of the object during the drying of the object.

Abstract: An automatic replacement apparatus for a feed material includes a discharge unit discharging a feed material to the outside, a pair of feed units disposed to be adjacent to the discharge unit and having a feed roll around which the feed material is wound, and a pair of material joint units respectively provided in the pair of feed units connecting a front end of a first feed material waiting in a first feed unit, one of the pair of feed units, and an end of a second feed material being transferred from a second feed unit, the other of the pair of feed units, to the discharge unit in a butt joint manner.

Abstract: The present invention relates to an apparatus and method for inputting a password using a game. The method includes displaying, on a display unit, a password image corresponding to at least one password information, displaying, on the display unit, at least one obstacle image, displaying, on the display unit, a character image moved based on movement information received from an external input unit, determining whether the character image is in contact with the password image, and controlling a user authentication procedure to be performed based on the at least one password information corresponding to the password image when the character image is in contact with the password image.

Abstract: The present invention provides a tension regulating apparatus for a chain of a leftover food treating device which comprises an agitation shaft having agitation blades and rotatably installed in an agitation tank and a rotation unit installed on one side of the agitation shaft for providing the agitation shaft with a rotational force, the tension regulating apparatus comprising: a driving sprocket engaged with a driving shaft of a driving motor provided on one side of the agitation tank; a driven sprocket connected to the driving sprocket by a connecting chain and engaged with one end of the agitation shaft; and a tension sprocket provided between the driving sprocket and the driven sprocket, for regulating the tension of the connecting chain.

Abstract: A method and an apparatus for pulse-amplitude equalization of rational harmonic mode-locked optical pulses provides modulation voltages greater than a switching voltage of a dual-electorde Mach-Zehnder modulator to electrodes of the Mach-Zehnder modulator, so that rational harmonic mode-locked optical pulses experience the same transmission coefficient through the Mach-Zehnder modulator, to thereby achieve amplitude-equalized rational harmonic mode-locked optical pulse trains.

Abstract: A method and server for adjusting a character ability value is provided. Advantages/disadvantages occurring due to a character's ability value difference can be adjusted since ability values associated with the characters can be adjusted in real time when the characters are matched against each other in a program running on a client, an imbalance in ability values occurring due to level differences can be solved by adjusting ability values of objects associated with the characters, such as a summoned creature, a pet, a throwing weapon, and projectile, and a combat can be performed under a condition of equal ability values. Consequently, participation in a service can be encouraged by arousing a user's interest.

Abstract: A system and method for providing a service of playing an accompaniment/musical performance is disclosed. In order to embody the system and method for providing the service of playing the accompaniment/musical performance, virtual orchestra system (VOS) files, which is converted from digital music files, e.g., musical instrument digital interface (MIDI) files and includes play order notes and sound data for each musical instrument capable of being played, are used. A server provides the VOS files through a network, e.g., a local area network (LAN), an Intranet, a value added network (VAN), an Internet or a public switched telephone network. A music is selected by a user through at least a client terminal. The play order note for each musical instrument is provided and the sound data for each musical instrument is played based on the play order note, thereby playing in solo or in concert. (At this time, sound for the others musical instrument is silent or used as a background music.
