A build region limitation unit for an additive manufacturing apparatus includes a movable unit fixed to a build table and a non-movable unit placed on a base frame. The movable unit includes a first anti-scattering frame provided to protrude upward. The non-movable unit includes a flat plate that covers a first build region with a portion other than an opening and forms a second build region, and a second anti-scattering frame that is provided to protrude downward at an outer periphery of the opening. The first anti-scattering frame surrounds the second anti-scattering frame with a gap therebetween.

Provided is a laminate molding apparatus including a chamber, a laser irradiation device, an inert gas supply device, a fume collector, and an evacuate device. The evacuate device includes an intake port, an evacuate amount adjusting portion, a controller, and an evacuate port. The intake port is connected to any part of the laminate molding apparatus through which the inert gas flows, and takes in the inert gas. The evacuate amount adjusting portion adjusts an evacuate amount of the inert gas. The controller controls the evacuate amount adjusting portion to evacuate the inert gas such that an atmospheric pressure in the chamber and an external atmospheric pressure become uniform within a range in which leakage of the inert gas from the chamber is suppressed. The evacuate port evacuates the inert gas from which fumes have been removed to the outside of the laminate molding apparatus.

A disk drive apparatus which consumes less power to control the movement of a head on the basis of servo signals which are intermittently reproduced from a disk-like recording medium has a servo signal processing circuit driven by a clock signal for generating a head control signal from the servo signals which are intermittently reproduced from the disk-like recording medium and for generating a processing period signal indicative of a processing period in which the servo signals are being processed, a head driving circuit to control the movement of the head on the basis of the head control signal, a clock generator to supply the clock signal, a servo signal reproduction detecting circuit to detect a servo signal reproducing interval in which the servo signals are being reproduced form the disk-like recording medium, and a circuit to control the supply of the clock signal to the servo signal processing circuit on the basis of detection of the servo signal reproducing interval by the servo signal reproduction detecting circuit and the processing period signal from the servo signal processing circuit.
