Abstract: An advertisement system and method of a printer is proposed. Particularly, customized advertisement content is displayed on a computing device interworked with the printer during a print waiting time, or the customized advertisement content for each user is output on a printout of an output device. In the advertisement system of the printer, a user-customized advertisement is displayed during the print waiting time that inevitably occurs when outputting to the printer, or user-customized content is output according to a layout and design of the printout. In addition, the advertisement system of the printer provides a rental fee discount, point and reward accumulation of the printer according to an amount of time the advertisement is output from the output device and an advertising print volume, so that a user who rented the printer may generate revenue and an advertiser may improve advertising effectiveness through the advertisement system of the printer.

Abstract: Provided are a gas injection device and substrate processing apparatus using the same. The gas injection device includes a plurality of gas injection units disposed above a substrate support part rotatably disposed within a chamber to support a plurality of substrates, the plurality of gas injection units being disposed along a circumference direction with respect to a center point of the substrate support part to inject a process gas onto the substrates. Each of the plurality of gas injection units includes a top plate in which an inlet configured to introduce the process gas is provided and an injection plate disposed under the top plate to define a gas diffusion space between the injection plate and the top plate along a radius direction of the substrate support part, the injection plate having a plurality of gas injection holes under the gas diffusion space to inject the process gas introduced through the inlet and diffused in the gas diffusion space onto the substrate.

Abstract: The present invention provides a composite tool bar which has a composite body part (10) covered with a covering (20), with a plurality of bites (TO1-T05) mounted on the composite body part (10) along a longitudinal direction. The composite tool bar includes a first insert (240) which is inserted into the composite body part (10). A bite mounting hole (210) is provided in the first insert (240) to receive a bite therein. A bite height adjusting hole (220) is axially aligned with the bite mounting hole (210) to receive therein a bite height adjusting bolt (BO1-B05). The composite tool bar further includes a second insert (250) which is inserted into the composite body part (10) to be coupled to the first insert (240). A bite holding hole (230) is provided in the second insert (250) to receive therein a bite holding bolt (B06-B10).

Abstract: A robot arm has an impact absorption structure for absorbing impact energy caused by a collision to protect a person from injury and the robot arm from being damaged. The robot arm includes a plurality of rigid beams provided at both end portions thereof to define a frame of the robot arm, and side members made of an elastic material and provided between the plurality of rigid beams to define an appearance of the robot arm and absorb the impact energy. Each side member includes a sheet made of a plastic material, a foam or honeycomb structure, and a fiber reinforced composite material attached to the sheet.
