Abstract: A system for depositing a material includes a die and a flow guide. The die includes an opening and a cavity communicating with the opening. The die is configured to extrude the material in a principal deposition direction through the opening. The flow guide is disposed in the cavity and is configured to shape a flow of the material extruded by the die. The flow guide includes a flow narrowing portion and a flow shaping portion. The flow narrowing portion extends in a width direction perpendicular to the principal deposition direction so as to block the material from flowing through in the principal deposition direction. The flow shaping portion extends downstream from the flow narrowing portion in the principal deposition direction. A width of the flow shaping portion is smaller than, or decreases from, a width of the flow narrowing portion.

Abstract: A fire-fighting virtual reality simulator allows the trainee to move in a virtual space in various complex virtual fire disaster situations and perform a suppression of a virtual fire and a confrontation training. An experience interactive simulator for providing a trainee with a floor movement that may occur in a fire disaster situation so that the trainee wearing HMD in a virtual fire-fighting training has the same sense of feeling as that in an actual fire-fighting training is provided. For the realistic content experience, a physical floor movement, such as tilting, falling, and shaking of the floor is reproduced using a base motion, thereby providing a floor movement that enables a sense of feeling similar to a fire disaster situation.
