Abstract: A 3-dimensional object-forming apparatus is provided which may avoid lowering of irradiation efficiency of laser light due to fumes and so forth while avoiding lowering of quality of the formed object. A shroud 20 includes an inside partition wall portion 21 that demarcates an inside space S1 which extends from one end opening 202 to another end opening 206, and an outside partition wall portion 22 that opens in the other end opening 206 of a shroud 20 on an outside of the inside space S1 and demarcates, together with the inside partition wall portion 21, an outside space S2 which closes in a position closer to the one end opening 202 than the other end opening 206 of the shroud. A ventilation area of the inside space S1 in the other end opening 206 of the shroud 20 is larger than the ventilation area of the inside space S1 in an upstream portion closer to the one end opening 202 than the other end opening 206.

Abstract: The vehicle floor carpet of the present invention includes a skin layer, a thermoplastic resin layer, and a base layer in this order, the thermoplastic resin layer has a plurality of open hole parts penetrating through the thermoplastic resin layer in the thickness direction, and the open hole parts are arranged on recesses in a surface of the skin layer or recesses in a surface of the base layer at the side of the thermoplastic resin layer.

Abstract: The three-dimensional object building apparatus includes a powder delivering unit that delivers a powder on an object building area, a powder flattening device that flattens the powder delivered from the powder delivering unit to form a powder layer, and a light beam radiating unit that is disposed above the object building area and radiates a light beam on the powder layer to sinter or melt solidify the powder for building an object. The three-dimensional object building apparatus also includes a transferring mechanism that moves the light beam radiating unit in three-dimensional directions, and a shroud that moves integrally with the light beam radiating unit and surrounds a space above an area of the powder layer that is smaller than the object building area around a radiation of the light beam. The powder delivering unit and the powder flattening device move integrally with the light beam radiating unit.

Abstract: In a method of grinding ball grooves formed in a workpiece with a grind stone, the grind stone is fed in a direction of a longitudinal axis of the ball groove in a condition in which an axis of rotation of the grind stone is inclined in the direction of the longitudinal axis of the ball groove relative to a plane which perpendicularly crosses the longitudinal axis of the ball groove. An apparatus for grinding the ball groove has an apparatus bed which is movable in a direction of a longitudinal axis of the ball groove relative to a work holder for holding a workpiece, a supporting bed which is provided on the apparatus bed, a grind stone holder which rotatably mounts on a front end thereof a grind stone for grinding the ball groove, and an electric motor and a gear mechanism for rotating the grind stone. The grind stone holder, the electric motor and the gear mechanism are mounted on the supporting bed.
