Abstract: Provided is an undersea mining base capable of corresponding with slopes and undulations of seabed ore deposits. The undersea mining base includes a seabed mineral mining device configured to form a pit in a seabed ore deposit and a platform equipped with the seabed mineral mining device and capable of self-traveling in at least one of an X direction and a Y direction.

Abstract: The quality of the briquettes granulated by a briquetting machine is improved. A briquetting machine control device samples the briquette that have been produced to measure an apparent density and a crush strength of the sampled briquette (step S10), and controls each operation set value adjusting unit (4, 6, 7) of the briquetting machine so that the actual measurement values come closer to predefined briquette quality target values (step S20 to step S60).

Abstract: A briquette inspection device and a briquette inspection method are capable of measuring at least a volume and a crush strength of an identical briquette sample. The briquette inspection device 10 is provided with: a volume measuring unit 2 for measuring the volume of the briquette sample B by laser scanning; and a crush strength measuring unit 3 for measuring the crush strength of the briquette sample B by pressing down and crushing the briquette sample B after the volume measuring unit measures the volume of the briquette sample.

Abstract: An elevator device for a television camera which reduces noise to a low level, which moves up or down a television camera at high speed regardless of whether the moving distance is short or long, and which makes it possible that camera position movement at high speed is compatible with smooth speed change in low speed range in film shooting. The elevator device for a television camera comprises a stationary cylinder 1, a movable cylinder 3 on which a television camera 2 is mounted, and a linear motor 4 for moving the movable cylinder 3 up or down along the stationary cylinder 1, wherein the movable cylinder 3 is in the form of a telescopic tube and includes a pulley 32 and a wire rope 33 for extension and contraction of the movable cylinder 3 when the movable part 24 of linear motor 4 is moved up or down.
