| 20100276105 | METHOD AND APPARATUS FOR REMOVING A CASTED PART FOR USE IN A DIE CASTING MACHINE - A method for removing a casted part, for use in a die casting machine comprises the steps of setting a position in which a chuck performs an operation to grasp a casted part attached to a movable mold as a position from which the casted part is to be removed, and setting a relative positional relationship between a handle portion which is a part of the casted part attached to the movable mold to be grasped by the chuck and a movable die plate. The method further comprises the step of advancing the chuck between the movable mold and the fixed mold and positioning the chuck at the position from which the casted part is to be removed, in parallel with the movement of the movable die plate. Additionally, the method comprises the steps of stopping the movable die plate when the handle portion of the casted part attached to the movable mold reaches the position from which the casted part is to be removed, grasping the handle portion of the casted part by using the chuck, and removing the casted part from the movable mold. | 11-04-2010 |

| 20100047479 | SMECTIC AEROGEL AND METHOD FOR PRODUCTION THEREOF - The present invention is to provide a high quality smectic aerogel which is not brittle and a method for producing the smectic aerogel by using a host material comprising a mixture of a smectic liquid crystal and a UV-curable material or a host material comprising a smectic UV-curable material and by selecting an appropriate host material. A smectic aerogel comprising 4-nonyl-4′-cyanobiphenyl (9BC) and air bubbles can be produced, wherein hexagonal or pentagonal air cells are separated from each other by a smectic layer comprising a smectic liquid crystal. The thickness of the wall of the smectic layer at the boundaries of the air cells is about 24 μm, which corresponds to about 6000 smectic layers. The thickness of the wall of the smectic layer at the boundaries can be varied. Particularly, the thickness can be reduced to as thin as several smectic layers. | 02-25-2010 |
