Abstract: A chemical drum replacement apparatus includes an automated robotic assembly configured to attach or detach a drum cap and a coupler module to or from a chemical drum and a transfer robotic assembly configured to transfer the chemical drum, where the automated robotic assembly includes a travelling module configured to move the automated robotic assembly, a manipulator on an upper surface of the travelling module, and a gripper at an end of the manipulator, the gripper configured to attach or detach the drum cap and the coupler module to or from the chemical drum.

Abstract: A sample analysis system includes a loading/unloading part including a container carry-in device, by which a container containing a sample is carried in, and a container carry-out device, by which an empty container from which the sample has been removed is carried out, and an analysis part including a buffer device configured to store the container, an analysis device configured to analyze the sample contained in the container, a cleaning device configured to clean the container, and a transfer robot configured to convey the container.

Abstract: A gas supply stage includes a gas supply cabinet and a fastening vehicle. The gas supply cabinet includes a cabinet frame including an inner space configured to house a gas container and a holding module including a connector holder configured to be detachably fastened to a valve nozzle. The fastening vehicle includes a traveling unit configured to travel in a facility space in which the gas supply cabinet is installed, a multi-axis robot attached to the traveling unit, and a module gripper mounted to the multi-axis robot and configured to detachably grip a valve manipulation module and the holding module.

Abstract: An end cap holder may include a base block and a holding block. The base block may be configured to provide an end cap, which may be at a nozzle of the gas cylinder, with a torque for combining/separating the end cap with/from the nozzle. An angle correction groove may be formed at a first surface of the base block oriented toward the end cap. The holding block may be rotatably receivable in the angle correction groove to hold the end cap. The holding block may selectively make point contact with the base block to transmit the torque of the base block to the end cap. Thus, the holding block may accurately hold the end cap tilted to a vertical axis or a horizontal axis.

Abstract: A loose type pneumatic valve and a loose type pneumatic valve module, the loose type pneumatic valve including a valve body including a pneumatic passage therein; a valve head on the valve body, the valve head being coupleable with an actuator; a stem on the valve head, the stem being configured to open and close the pneumatic passage; and at least one alignment socket on the valve head, the at least one alignment socket being configured to align the valve head with the actuator.

Abstract: The present invention provides a combined system of mirror and mobile computer or communication device. In one embodiment of the invention, a portable computer comprises a top unit comprising a visual display and a base unit comprising a plurality of key buttons, a mouse, and other peripheral devices. The base unit is coupled to the top unit, and the top unit has a mirror attached to its exterior surface. The top unit may comprise a recess area or pocket on its exterior surface to hold a mirror in place and may comprise a cover or lid to protect the mirror. The mirror may be also disengageably attached to the top unit of the computer using a detachable mechanism. In another embodiment of the invention, the mirror is installed on the base unit of the portable computer so that the mirror is exposed and available for use when a user opens the computer, and covered when the user closes the computer.
