  • Patent number: 5804046
    Abstract: A collimator having a particle getter function, and a thin-film forming apparatus equipped with the collimator disposed between a target and a wafer. The collimator is fabricated by assembling particle getter sheets into a lattice, honeycomb, or other structure having a number of rows of openings and fixing the assembly into a frame. The particle getter sheets refers collectively to sheets and plates to be assembled integrally to provide a surface having excellent particle capturing and holding actions. Typically, the collimator is a lattice assembly of embossed, slitted particle getter sheets. The film deposited on the collimator is kept from peeling off, without deteriorating the collimator performance.

  • Patent number: 5792268
    Abstract: Apparatus for supporting and holding a circuit board in place in a machine for screen printing a major surface thereof with solder paste. The apparatus includes a member with a surface on which a circuit board rests as the board receives solder paste printing through a screen. The surface has a main groove and distribution grooves that intersect the main groove in communicating relationship therewith at spaced locations along its length. Further, the member has an air removal passageway extending therethrough from one side to the opposite side thereof. The passageway terminates on the one side of the member at an opening located in the main groove. A circuit board resting on the surface over the grooves is held in place during screen printing with solder paste as a result of reduced air pressure established in the grooves when air is withdrawn therefrom through the passageway.

  • Patent number: 5702734
    Abstract: A molded parison handling apparatus for removing hollow plastic parisons used in the manufacture of oriented plastic bottles from an injection molding machine includes a base having an arm coupled to the injection molding machine. A carriage mounted on the arm moves in a first dimension into and out of the space between the molding elements of the molding machine. A frame cooling unit coupled to the carriage engages the body portion of a set of parisons as they are released from the molding machine. A first motor moves the cooling apparatus to any of three preselected positions along the first dimension located outside the molding machine. A transfer assembly includes three sets of grabbers mounted on a gantry for movement with respect to the base. One set of grabbers grabs the finish portion of the parisons from the cooling apparatus.

  • Patent number: 5700430
    Abstract: A device for dispensing a volatile substance includes a gas-fueled, portable heat source. The heat source has a combustion nozzle capable of supporting a flame. The device includes a sole plate for heating the volatile substance and heat transfer means for enclosing the combustion nozzle and transferring heat from the flame to the sole plate. A heat box substantially surrounds the heat transfer means and sole plate. The heat box has a window through which volatile substances released from the sole plate may escape. The device also has a housing within which the heat box is held in spaced relation from the housing, the housing having a housing window adjacent to the heat box window. By use of the device, a flame at the combustion nozzle heats the sole plate to volatilize a volatile substance placed thereon, which may then escape into the atmosphere through the heat box window, with the housing remaining cool.

  • Patent number: 5688476
    Abstract: Disclosed herein is a single step sterilization wrapping material suitable for use, as an example, in wrapping surgical instruments and supplies for sterilization, transportation and storage. The material includes separate inner and outer wraps which, unlike previous wraps, are joined to one another. Common wrapping techniques involve wrapping items to be sterilized with two separate sheets of wrap. The present invention provides separate wraps which can be specially engineered to deliver specific properties for each sheet and then joined to one another so as to permit wrapping and opening in a neat single step process which increases efficiency and saves time and money. In special situations the outer wrap can be engineered with increased strength, the inner wrap with increased barrier properties and the inner and outer wraps can be made visually distinct from one another so that improper wrapping or opening is not a problem.

  • Patent number: 5681539
    Abstract: A bracket for fixating medical instruments or other articles includes a base member with a plurality of spaced-apart fingers extending up from the base member. A recess is formed in a side wall of at least one finger, which recess faces the adjacent finger. Also, a sheath engages around each finger which sheath has a flexible, resilient side wall which overlies any recess in that finger and defines therewith a void. When an article is wedged into the space between the one and the adjacent finger, it will snap into a stable position opposite the void so that the article is resiliently engaged and fixated by the overlying sheath wall.

  • Patent number: 5679308
    Abstract: A porous material such as paper made of cellulose fiber prepared by a preservation method of the present invention can retain excellent folding endurance after being subjected to accelerated aging treatment performed at a high temperature with high humidity. The method for preserving the porous material includes the steps of placing a porous material made of mainly cellulose fiber in an airtight chamber, evacuating the airtight chamber to reduce the pressure, supplying an ammonia gas into the airtight chamber to thereby neutralize an acidic substance present in the porous material, simultaneously permitting the porous material to absorb the ammonia gas, and supplying an ethylene-oxide-containing gas into the airtight chamber to thereby react with an ammonia present on the surface of and inside the porous material, thus producing an alkaline substance principally consisting of triethanolamine and allowing the alkaline substance to attach to the porous material.
