Abstract: A space oven operates in microgravity environments by forcing convection towards the center through a unique heating element and airflow design. The space oven includes a tubular chamber, a heating rack, a heating system, a cooling system, a hatch, a user interface, a microcontroller, an enclosure, at least one first vent, at least one second vent and at least one temperature sensor. The tubular chamber is the cooking area. The heating rack holds consumables in place. The heating system heats up consumables. The cooling system prevents any overheating. The hatch closes off and allows access to the inside of the tubular chamber. The user interface allows a user to input commands. The microcontroller manages the electronic components. The enclosure protects the tubular chamber. The at least one first vent and the at least one second vent reduce pressure buildup. The at least one temperature sensor monitors the internal temperature.

Abstract: Disclosed is an air circulation device for an outdoor cooking appliance such as a grill. The device helps circulate air more consistently and efficiently by providing slats that direct rising air in a cyclonic arrangement. By providing this cyclonic effect, the air circulation device can distribute heat and smoke more evenly to the food being cooked and improve smoke penetration, heat efficiency, and the evenness of cooking.

The substrate treating apparatus includes a chamber providing a space in which a substrate is treated, a support unit supporting the substrate inside the chamber, a laser unit irradiating laser to an edge region of the substrate, a vision unit capturing the edge region of the substrate to measure an offset value of the substrate, and an adjustment unit adjusting an irradiation location of the laser based on the offset value of the substrate.

Abstract: A laser apparatus including a stage. A target substrate is mounted on the stage. The laser apparatus further includes a coupling unit disposed below the stage and coupled with a conveying unit, the conveying unit conveying the stage. The laser apparatus additionally includes a discharge unit disposed at a predetermined position for laser machining, configured to communicate with the coupling unit when docked with the coupling unit, and configured to discharge foreign matter that is generated during laser machining.

Abstract: A laser processing apparatus emits processing light, measurement light, processing guide light, and measurement guide light with which a surface of a workpiece is irradiated. Respective wavelengths of the processing guide light and the measurement guide light are set to wavelengths at which a deviation amount between an irradiation position of the processing guide light and an irradiation position of the measurement guide light due to a chromatic aberration of magnification of a lens, and a deviation amount between an irradiation position of the processing light and an irradiation position of the measurement light due to the chromatic aberration of magnification of the lens are equal to each other. Therefore, positioning of spot positions of a plurality of laser lights having different output differences can be realized with high accuracy and high speed.
