    Abstract: A vacuum carrier module includes a substrate having at least one hole and an edge region. There is at least one support on a top surface of the substrate. Further, a gel film is adhered to the edge region of the substrate. The at least one hole fluidly connects a reservoir located above the top surface of the substrate. A method of using a vacuum carrier module includes planarizing a gel film by passing an alignment material through a hole in a substrate to contact a first surface of the gel film, positioning at least one chip on a second surface of the gel film opposite the first surface. The method further includes encasing the at least one chip in a molding material and applying a vacuum to the first surface of the gel film.

  • Publication number: 20140242231
    Abstract: A rotary molding system for molding food products, mold cavities formed when a mold shell rotates mold shapes disposed along the mold shell into a fill position between a fill plate and a wear plate. Molded food products are removed from mold cavities using knock-out cups, the use of air pressure, or the use of a vacuum source disposed below the mold cavity, without the need to slow the rotation of the mold shell. Knock-out cups may be used with a heating system to reduce accumulation of unwanted materials on the knock-out cups. The rotary molding system can also be used to form products with contoured surfaces. A smart tagging system can be used to ensure that compatible sets of mold shells and knock out cups are being used. A vacuum region may be disposed upstream of the fill position to remove air within the mold cavity prior to filling.

The mold has two opposing side walls; a bottom wall; a front wall; a top side with an opening through which the block can be removed from the mold; a cover, and a rear side through which liquid, such as concrete, can be poured into the mold. Extending from the two side walls are a pair of trunnions about which the mold is rotatable, such that when the mold is suspended by the trunnions and the mold is empty, gravity rotates the mold from a block-removal orientation in which the top side faces upwards to a mold-filling orientation in which the rear side faces upwards. The trunnions are also positioned such that when the mold is filled with the liquid, gravity rotates the mold from the mold-filling orientation to the block-removal orientation.

    Abstract: A mold for imprinting a patterned region by imprint lithography is provided with a peripheral groove around the patterned region. The groove is connected, as by channels through the mold, to a switchable source for gas removal to prevent bubbles and for the application of pressurized gas to separate the mold and substrate. In use, the mold is disposed adjacent the moldable surface and gas is withdrawn from the patterned region through the groove as the mold is pressed toward and into the moldable surface. At or near the end of the imprinting, the process is switched from removal of gas to the application of pressurized gas. The pressurized gas passes through the groove and separates or facilitates separation of the mold and the moldable surface.

    Abstract: The present invention provides a method for separating a mold from solidified imprinting material that includes creating deformation in the template in which the mold is included. The deformation is sufficient to create a returning force that is greater than an adhesion forced between the solidified imprinting material and the mold. For example, the deformation may result from a pressure differential created between the mold and a side of the template disposed opposite to the mold. In this manner, the distortion may be undulations in the template of sufficient magnitude to contact a substrate upon which the solidified imprinting material is disposed.

    Abstract: Disclosed are a molded article picker for a post-mold device and a related method for the use of the molded article picker for handling a molded article. The molded article picker includes a floating element being configured to be movable between an extended position and a retracted position and biased in the extended position. Furthermore, the molded article picker comprises a pressure structure extending through the floating element. The floating element is cooperable with the molded article to define a substantially enclosed volume including the pressure structure. The pressure structure is configured such that by evacuating the substantially enclosed volume the molded article is sealed to the floating element and the floating element is drawn into the retracted position, thereby transferring the molded article to the molded article picker.

  • Publication number: 20070278705
    Abstract: Contact lens delensing methods are described, and the present delensing methods include using a gas to facilitate separation of a polymerized contact lens product from a contact lens mold member. The contact lens mold member is compressed to deform a portion of the mold member, and gas, such as air, is directed toward the polymerized contact lens product in contact with the portion. The contact lens mold member can be compressed as the mold member, and lens product, rotate. A vacuum device can be used to separate the polymerized contact lens product from the contact lens mold member after compressing the portion of the mold member and directing the gas towards the mold member. Delensing systems used to practice the present methods are also described.

  • Patent number: 7198479
    Abstract: An ejector with multi-ejection pins is used in the post-processes of the semiconductor industry and is used by a selection device to choose a predetermined quantity of ejection pins. When a propelling device lifts the selection device, a pin-base vertical driver controls the vertical motion of a pin base, and a pin-base motion device controls the planar motion of the pin base; the chosen ejection pins can be lifted to elevate the respective dies for separation from adhesive film.

  • Patent number: 6976837
    Abstract: A compact disc (CD) molding apparatus. The CD molding apparatus comprises a movable mold, a fixed mold, a mold cavity, an outer ring, a gas passage, an outlet and an auxiliary gas channel. The movable mold is disposed adjacent to the fixed mold. The mold cavity is defined between the movable mold and the fixed mold. The outer ring surrounds the mold cavity, and the outlet is defined between the fixed mold and the outer ring. The gas passage is defined between the fixed mold and the outer ring and connects the mold cavity and the outlet. Particularly, the auxiliary gas channel is disposed in the fixed mold and connected to the gas passage to facilitate exhaust of high temperature gas from the mold cavity, wherein a material is injected into the mold cavity and the high temperature gas passes through the gas passage before exiting through the outlet.

  • Patent number: 6929461
    Abstract: A method and apparatus for making multiple layer optical discs is applied to separate the base plate from the mold plate. The apparatus includes a first adhesive ending groove, a mold plate, a sealing member and an air-blowing axle. The adhesive does not cover the area around the first and second openings and the first and second adhesive ending grooves, so an enclosed cavity is formed between the first and second openings. The air-blowing axle passes through the second opening and encloses the cavity but leaves injestion ports in the cavity so that air can be injected into the cavity for separating the base plate and the mold plate while the second recording layer and the adhesive layer adhere to the base plate.

  • Patent number: 6838098
    Abstract: Method and system for continuously producing pieces of liquid-filled gum material. An extruded rope of liquid-filed gum is sized and separated into individual pieces of gum. A rotating drum mechanism having a die ring and cutter ring with mating die members separate the rope of gum material into individual pieces. Pairs of cam-operated plunger members compress and form the pieces of gum material in the die cavities. Angled grooves in the die members prevent portions of the gum pieces from being chipped-off during formation. Guide pin members are positioned between rider members on the plunger members. A feed chute with air assist transfers the gum rope from a sizing table to the rotating drum mechanism. A stripper member insures that the formed pieces of gum material are removed from the drum mechanism. Portions of the drum mechanism can be selective heated and cooled, or not cooled at all. The invention provides a more efficient system for continuous, high production operation.
