Abstract: A casting device capable of manufacturing products in a short cycle time; and a casting method using this casting device. The casting device includes: a pressurized furnace; a mold having a cavity formed therein; a stalk; at least a first hot water tap in a cylindrical shape connecting the cavity and an end of the stalk on the downstream side in the molten metal filling direction and guiding the molten metal supplied to the stalk to inside the cavity; and a filter member provided in the first hot water tap. The filter member includes a flange extending along the extension direction of the first hot water tap and abutting an inner wall surface of the first hot water tap. A coolant passage having coolant flowing therethrough is provided in the vicinity of the inner wall surface.

Abstract: A gear-grinding multilayer grindstone includes: a first thread-shaped grindstone and a second thread-shaped grindstone that are fixed to each other, such that the first and second thread-shaped grindstones have a rotational axis that is common to the first and second thread-shaped grindstones; and a thread-shaped groove that is provided in a first outer circumferential surface of the first thread-shaped grindstone and a second outer circumferential surface of the second thread-shaped grindstone. The thread-shaped groove extends continuously over the first outer circumferential surface and the second outer circumferential surface. The second thread-shaped grindstone is constituted by abrasive cloths that are laminated on each other, and has a higher elasticity than the first thread-shaped grindstone.

Abstract: The present invention is intended to provide an adaptive optics system and an optical device that allow correction of wavefront phase aberration with higher accuracy than before and have a wider correction range than the conventional ones, regardless of the distance between the observation target and the fluctuation layer, and the size of the observation target. An adaptive optics system includes: a wavefront phase modulator that makes aberration correction to incident light and emits the corrected light; and an imaging-conjugated position adjustment mechanism that adjusts freely within a specimen the position of a surface imaging-conjugated with a fluctuation correction surface formed by the wavefront phase modulator. The imaging-conjugated position adjustment mechanism adjusts the fluctuation correction surface to be imaging-conjugated with a fluctuation layer existing in the specimen.

Abstract: A casting device is provided with: a pair of cylinders; a core pin holding member to which core pins are attached; and a pair of bent members. The cylinder is disposed in parallel with a second limb of the bent member, and a rod is coupled to a surface on the inner side of a first limb of the bent member. The second limb is coupled to the core pin holding member via a coupling mechanism so as to be freely attachable to/detachable from the core pin holding member.

Abstract: A casting device is provided with: a positioning member that is provided to a base and comes into contact with an upper mold and a slide member to define the positions of the upper mold and the slide member at the time of mold clamping; and a restraining force-applying mechanism for applying a restraining force to the slide member in a direction opposite a pressing force acting on the positioning member from the slide member at the time of mold clamping of the slide member.

Abstract: Provided is a casting die 1 including a base 3, a lower mold 4, a horizontal sliding mold 5, and an upper mold 6. The lower mold 4 is configured by a lower mold body 10 and a lower mold stage 11. A guide member 17 is mounted on the lower mold stage 11 so as to freely move in the up and down direction with respect to the lower mold stage 11. The horizontal sliding mold 5 is configured to slide on the guide member 17 and the lower mold body 10. The guide member 17 is provided with a locking part 17a which locks with a lateral edge part of the lower mold body 10 when the lower mold body 10 is separated upward from the lower mold stage 11, so that the lower mold body 10 and the guide member 17 separate upward together.

Abstract: Provided is a casting mold including a lower mold 4 fixed on a base 3, a plurality of horizontal sliding molds 5 to 8 which slide freely on the base 3 between a mold-opening position and a mold-closing position, an upper mold 9, and sliding mechanisms 12, 25 which slide the horizontal sliding molds 5 to 8 in the sliding directions. When sliding the horizontal sliding molds from the mold-opening position to the mold-closing position, the sliding mechanisms 12, 25 cause force to act on a lower section of the horizontal sliding molds 5 to 8 and prevent force from acting on an upper section of the horizontal sliding molds 5 to 8.
