Abstract: The present invention relates to a chamfering device and a chamfering method and, more particularly, to a device for chamfering an edge of a glass substrate, comprising: a heating element which contacts a corner of the edge of the glass substrate and makes heat penetrate the edge of the glass substrate; and a moving unit for sliding the heating element along the edge of the glass substrate, wherein the moving unit slides the heating element so that the corner of the edge of the glass substrate is naturally peeled along the moving direction of the heating element so as to continuously generate chips to chamfer the glass substrate.

Abstract: A display tool comprises a first member and a second member that visually represents a character, wherein states that a relative positioning between the first member and the second member can take include a first state and a second state in which the first member is more difficult to hold than in the first state.

Abstract: The present invention relates to a system for showing an image, and more particularly, to a system for showing an image having a game function of performing an interactive game for viewers in a theater. To this end, the present invention provides a system for showing an image, including: a plurality of motion chair assemblies including a predetermined number of motion chairs; a center server configured to control the motion chair assembly; and a screen configured to display an image output from the center server, in which a signal generated in the motion chair assembly is transmitted to the center server according to an image displayed on the screen, and when the generated signal does not accord with a preset condition, the center server operates the motion chair assembly, and when the generated signal accords with the preset condition, the center server does not operate the motion chair assembly.

Abstract: Provided is a system for controlling a seat effect for a facility of showing pictures, and particularly, a user on a rear line may easily and safely control an effect provided to the user himself/herself even while a seat is in motion operation at the time of showing pictures by controlling an effect synchronized with pictures by relaying control information inputted from the user on the rear-line seat by using an effect controlling device of a front-line seat, in the facility of showing pictures, which provides the effect (for example, a water shot, an air shot, or a scent) synchronized with the pictures to the user on the rear-line seat.

Abstract: Provided are a system and a method for controlling a motion using time synchronization between a picture and the motion, and more particularly, a motion code corresponding to a time code is prestored before showing the picture and the motion is controlled according to the prestored motion code when the picture showing starts while a current motion driving time is compared with a reference time of the picture and then synchronized to provide a high-resolution precision motion to a user while achieving accurate synchronization with the picture.
