Consequently, the entire surface thereof can be formed with a crystallized layer by performing water evaporation. As a result, molding at higher temperature can be realized, and high-density compacts can be stably obtained. Further, the solution L in which the lubricant is dissolved in a solvent into a homogeneous phase, is applied to a molding portion 1A, and then evaporated to thereby form crystals thereon, thus forming the crystallized layer.Type: GrantFiled: March 26, 2004Date of Patent: September 8, 2009Assignee: Mitsubishi Materials PMG CorporationInventors: Takashi Nakai, Kinya Kawase

According to this powder compacting method, even when the powder material has a non-uniform fill density distribution, a compact with a uniform density distribution can be obtained at a high productivity.Type: GrantFiled: November 5, 2001Date of Patent: May 2, 2006Assignee: Neomax Co., Ltd.Inventor: Atsushi Ogawa

Patent number: 6984117Abstract: An apparatus and methods of manufacturing seamless gaskets using expanded intercalated graphite worms, in which an annular die cavity has a central column with a charge inlet in a perimeter wall. Expanded intercalated graphite worms communicate from a source through the charge inlet in the annular die cavity for depositing a charge of expanded intercalated graphite worms within the die cavity. An upper pusher is movable from a first position distally spaced from an open end of the die cavity to a second position within the die cavity for compressing a first charge of expanded intercalated graphite worms. A lower pusher is movable from a first position to a second position during the compressing of the first charge of expanded intercalated graphite worms in the die. The upper pusher causes the lower pusher to move to the second position, so that a second charge of expanded intercalated graphite worms is received in substantially the same volume as the first charge.Type: GrantFiled: March 18, 2003Date of Patent: January 10, 2006Assignee: Acadia Elastomers CorporationInventors: Steven M. Suggs, Reid M. Meyer

Patent number: 6969244Abstract: The present invention aims to prevent heating and ignition of a material powder of a rare-earth alloy while reducing the oxygen content thereof so as to improve the magnetic properties of the rare-earth magnet. A rare-earth alloy powder is compacted by using a powder compacting apparatus including: an airtight container capable of storing a rare-earth alloy powder therein; an airtight feeder box moved between a powder-filling position and a retracted position; and an airtight powder supply device capable of supplying the rare-earth alloy powder from the container into the feeder box without exposing the rare-earth alloy powder to the atmospheric air.Type: GrantFiled: August 15, 2002Date of Patent: November 29, 2005Assignee: Neomax Co., Ltd.Inventors: Futoshi Kuniyoshi, Koki Tokuhara, Kunitoshi Kanno, Hitoshi Morimoto, Tomoiku Ohtani, Ryoji Ono

Patent number: 6955533Abstract: An apparatus for extending food dough is provided that is compact and has a relatively long conveying path for food dough that extends the food dough. Also, the apparatus can be easily cleaned and maintained. It includes a lower frame (3) having a food-conveying member to convey food dough in one direction, an upper frame (5) located above the lower frame, and a cluster of a plurality of extending rollers that are located within the upper frame. To extend the food dough the extending rollers are arranged to be endless and rotatable. The upper frame (5) can be moved up and down in relation to the lower frame (3) so that the cluster of the plurality of the extending rollers can be completely separated from the food-conveying member. Thus, the food-conveying member can be easily cleaned.Type: GrantFiled: February 14, 2002Date of Patent: October 18, 2005Assignee: Rheon Automatic Machinery Co., Ltd.Inventor: Michio Morikawa

Patent number: 6887416Abstract: A method and device for the production of a closure cap having a first part (16, 17) and a second part (18), joined together by at least one thinner section (19). The device contains a female mould part (11) and a male mould part (12), which are moveable relative to one another, in order to enclose a mould cavity. After the closing of the mould cavity, an additional mould part (14) is moveable relative to the mould cavity. In order to reduce the volume thereof, until the plastics material fills the mould cavity completely. Consequently the invention ensures that when compression moulding in the mould cavity, the closure cap and in particular also the thinner section (19) are formed completely in the mould provided.Type: GrantFiled: November 1, 2000Date of Patent: May 3, 2005Assignee: Crown Cork & Seal Technologies CorporationInventors: Dieter Schmitt, Raymond Stich

Patent number: 6736626Abstract: A machine makes blocks from pressed earth. A feed drawer having an open lower end and filled with loose earth is moved laterally across a planar surface into registration over a breech. A press foot is lowered to a level in the breech to receive loose earth from the feed drawer. The press foot is raised to a third level against a bucking foot to compress the loose earth in the breech into a block. Upon moving the feed drawer laterally into registration over the breech, the block will be pushed out of the path of the bucking foot. The feed drawer, and likewise a screed, having a lower edge notched to pass over a three dimensional surface of the press foot for pushing the block out of registration and for clearing above the three dimensional surface of the press foot.Type: GrantFiled: April 28, 2003Date of Patent: May 18, 2004Assignee: Foxfire, LLCInventor: David Lienau
