20100101721 | Heat pressing apparatus with puncture prevention function and method for producing woody material - [Problem to be Solved] When a wood raw material is heat-pressed in order to produce a woody material or woody board, steam is generated in an interior of the wood raw material. The heat-pressed wood raw material is then decompressed with the steam staying in the interior of the wood raw material. This causes a puncture or a rupture of the woody material. The puncture occurs in the last phase of the production process, thus spoiling the entire production process. In order to avoid the puncture, the wood raw material needs to be dried completely. This requires a large amount of energy. | 04-29-2010 |

20110030894 | VACUUM HEAT INSULATOR AND ITS MANUFACTURING METHOD - A vacuum heat insulator small in limitation in shape of applicable objects, and wide in application is presented. A vacuum heat insulator is formed of a plurality of core members of thickness of 5 mm or less made of glass fiber shaped nearly in a regular octagonal shape, being coated with a gas barrier enveloping member and evacuated in side. The core members are shaped in octagon, and disposed in lattice layout at specified intervals so as to form folding lines in four directions of vertical, lateral and oblique 45-degree directions, parallel to each side. In order that the plurality of core members may be located in independent spaces individually, the entire surface of the enveloping member around the core members is formed as heat seal parts, and it is foldable in four directions and is flexible.

The applied first force causes the heater/isolator plates to move toward each other along the main axis and thereby causes the collapse of each chamber zone volume and the application of bonding pressure onto the wafer pairs. | 04-05-2012 |
20120132360 | METHOD FOR LAMINATING ESSENTIALLY PLATE-SHAPED WORK PIECES - A method for laminating essentially plate-shaped work pieces with a thermally activated adhesive layer, particularly photovoltaic modules. Work pieces are inserted into a vacuum chamber having a compression element dividing the vacuum chamber in a gas tight fashion that can be raised and lowered by pressure differences. The compression element presses against the work piece which in turn presses against a heating plate which forms a lower side of the vacuum chamber, with processing heat being transferred into the work piece to soften the adhesive. The work piece is first impinged by the compression element with a slight load from approx. 2% to 10% of the defined processing load, and is simultaneously kept below the adhesive activation temperature. Thereafter, the slight load is lifted off the work piece and the work piece is heated to the activation temperature and impinged via the compression element with the processing load. | 05-31-2012 |

20140060731 | Method and System to Reduce Porosity in Composite Structures - In an embodiment of the disclosure, there is provided a method to reduce porosity in a composite structure. The method adds an additive to a resin material to form an additive-resin mixture. The method combines the additive-resin mixture with reinforcement fibers to form a composite prepreg material, and in turn, a composite structure. The method heat cures the composite structure in a heating apparatus under a vacuum device at the resin cure temperature, heats the composite structure to an increased temperature above the additive phase transition temperature, and maintains the increased temperature for a time period sufficient. The method reduces the increased temperature back down to the resin cure temperature to allow the additive gas to undergo a phase transition to a condense phase, resulting in a substantially reduced vacuum pressure, resulting in a reduction in a porosity of the composite structure. | 03-06-2014 |
