  • Patent number: 8790567
    Abstract: Provided is an electret having high piezoelectric properties. An electret sheet of the invention is characterized in that it comprises a synthetic resin sheet is electrified by injecting electric charges thereinto, that the synthetic resin sheet comprises two types of synthetic resins incompatible with each other, and that these synthetic resins form a phase separated structure and are cross-linked through a polyfunctional monomer. Therefore, positive and negative charges in an apparently polarized state are present in the interfacial portions between the two types of synthetic resins incompatible with each other. By applying an external force to the electret sheet to deform it, the relative positions of these positive and negative charges are changed, and these changes cause a favorable electrical response. Therefore, the electret sheet has high piezoelectric properties.

    Abstract: In order to realize a device and a method each capable of forming a lens with high accuracy and low costs, a lens forming device of the present invention includes a metal mold, an insulating substrate, a stage, a power source, a switch, and a UV radiating device. Dielectric resin is supplied onto the insulating substrate and a transfer surface of the metal mold is pressed to the dielectric resin so as to transfer a lens shape to the dielectric resin. At that time, the power source applies a voltage on the metal mold to generate an electric field between the metal mold and the insulating substrate so that an electrostatic attraction causes the dielectric resin to be attracted toward the transfer surface of the metal mold while the top of the dielectric resin has a sharp cuspate shape. Consequently, bubbles are less likely to be invade between the transfer surface and the dielectric resin, allowing transferring a highly accurate lens shape to the dielectric resin.

  • Patent number: 7682552
    Abstract: The present invention relates to a capacitive measurement method and system for a nanoimprint process, which arranges a plurality of electrode plates on both the backside of the master mold and the surface of the supporting base carrying the wafer substrate to form a plurality of capacitive structures. By monitoring the capacitance variation signal caused by the continuous variations in the thickness and the material properties of the resist during the imprint process, the status of the resist can be monitored and recorded, which is used as the references for determining the timing to demold in the nanoimprint process and for maintaining the flatness of the resist. Accordingly, the nanoimprint process can be automated easier and the quality and the throughput of of the nanometer scaled imprint product can be improved.

  • Publication number: 20090246309
    Abstract: A fine structure imprinting machine is provided which can surely and easily eliminate static electricity in removing a stamper from an imprinting object. The fine structure imprinting machine is adapted to bring the stamper with a fine concavo-convex pattern formed thereon into contact with the imprinting object, thereby to imprint the fine concavo-convex pattern of the stamper onto a surface of the imprinting object. The stamper has a conductive film on at least a pattern formation surface thereof. The stamper is fixed by a conductive holding member, the conductive film is connected to the holding member via the conductor, and the holding member is connected to a ground within the machine.

  • Publication number: 20090179358
    Abstract: An aspect of the present invention provides a method for producing a saturated norbornene resin film by melt film-forming method comprising discharging a molten resin molten in an extruder in a form of a sheet onto a traveling or rotating cooling support from a die so as to be solidified by cooling, wherein the molten resin discharged from the die is subjected to a close contact treatment which allows only the both end parts of the full width of the molten resin to closely contact to the cooling support. According to the aspect, a close contact treatment which allows only the both end parts of the full width of the molten resin discharged from the die to closely contact to the cooling support is conducted in the melt film-forming of a saturated norbornene resin film, a saturated norbornene resin film having an excellent surface quality without the surface quality defects such as step irregularities can be produced.

  • Publication number: 20080211134
    Abstract: A mold for the interior surfaces of one or more spirals is rotated and heated to a temperature sufficient to melt a weldable plastic such as LLDP or HDP plastic in a predetermined amount deposited thereon. Plastic powder not melted is recovered and redeposited until all the plastic powder is melted. The mold or molds are then actively cooled and the formed spiral is removed. An insulation layer is used to improve heating and cooling efficiency, and to control the areas where plastic is deposited. A cover closes the back of the mold.

  • Patent number: 7419373
    Abstract: A method and apparatus for forming laminate composite structures. At least two laminae, each containing electrically conductive reinforcing fibers, are placed upon each other in contacting relationship to form a generally layered structure. The layered structure may be subjected to heat to conductively transfer heat through the layered structure and thereby improve the surface contact between the two laminae. The layered structure is volumetrically heated by inductively transferring energy to the electrically conductive reinforcing fibers. The heated, layered structure is consolidated, such as by applying pressure and reducing the temperature of the layered structure. The consolidated structure is then quenched by rapidly cooling the consolidated structure in a directionally controlled manner about a midplane thereof.

  • Patent number: 7393193
    Abstract: A system is capable of making a metallic product with robust mechanical and electrical properties. The system includes a pressing stage configured to compress powder (e.g., MMC material) to form a green compact from the powder, a sintering stage configured to sinter the green compact to form a sintered structure from the green compact, and a consolidation stage configured to apply electric current to the sintered structure to form the metallic product from the sintered structure. The electric current is in the form of high density, short electric AC or DC pulses and results in consolidation of the sintered structure at grain boundaries to correct defects in the boundaries (e.g., areas of high electrical resistance) without melting the bulk metal to produce the metallic product. Such a system alleviates the need for coining process, which could fracture bonds and thus weaken the structure, following the sintering process.
