  • Patent number: 9694381
    Abstract: A combination nozzle and a device for applying a viscous material, particularly an adhesive, to a component edge includes two wide-slot nozzles lying close to one another. The first nozzle applies the viscous material and the second nozzle supplies a gas such as air for shaping the applied material bead. A nozzle mount has a guide roller placed on and movable about the edge of the component during application. A connector element via a connecting mechanism allows movement of the nozzle mount parallel to the surface normal on the component edge to press the guide roller against the edge during the application process by a spring mechanism. With the proposed combination nozzle and the proposed device, an optimal wetting of the component edge with the viscous material can be achieved, and additionally the component tolerances are compensated without the necessity of an elaborate sensor system.

  • Patent number: 5801062
    Abstract: For the removal of a small amount of fluid, in particular blood, from a sealed container, and the deposition of a drop of fluid on a slide by a dropper, and the subsequent spreading of the drop, the rear end of a dropper needle having a longitudinal channel which passes therethrough is pressed through a seal into a container. Once the needle is inserted into the container, a drop of fluid moves out of the container via the longitudinal channel to a slide. After depositing the drop of fluid on the slide, the dropper itself is used to spread and distribute the drop of fluid on the slide, so that spreading of the drop of fluid is facilitated and hazardous waste is reduced to a minimum. The dropper used for this purpose is made integral with a spreader.

  • Patent number: 5737178
    Abstract: An electrostatic chuck (20) comprises at least one mesh electrode (30) on an underlying dielectric layer (25), the mesh electrode having apertures therethrough. A monocrystalline ceramic (28) covers the mesh electrode (30). The monocrystalline ceramic (28) comprises a layer of large crystals substantially oriented to one another, the layer of crystals having a resistivity sufficiently high to electrically insulate the mesh electrode (30). The monocrystalline ceramic (28) further comprises integral bonding interconnects (40) that form a unitary structure with the layer of large crystals, the bonding interconnects extending through the apertures in the mesh electrode (30) to bond directly to the underlying dielectric layer (25), substantially without adhesive.

  • Patent number: 5700346
    Abstract: The present invention provides an automatic slide staining system which will process stained slides, such as cytology or histology specimens. The present invention includes two embodiments for the staining system. The first system includes a slide storage device, a slide transport apparatus, a first platen including a plurality of staining stations, a heating station, and a housing. In order to utilize the first embodiment of the system of the present invention, the stained slides are placed in the storage device. The slides are removed from the storage device and are processed on the various stations via the transport apparatus. The first system can be altered slightly so that a cover slip apparatus can be incorporated within the system. In order to do so, the heating station is removed. A cover slip dispensing apparatus replaces the heating station. This will permit for a cover slip to be placed on the stained slide after a complete transverse of the slide staining stations.

  • Patent number: 5688324
    Abstract: A substrate coating apparatus includes a stage, a coating liquid tank, and a moving mechanism. The stage holds the substrate to be vertical or inclined. The tank has a hollow body extending along the widthwise direction of the substrate, with opposing ends closed. The tank has a protruding front end surface which can be positioned facing the substrate surface to be coated. The tank has an outlet path having an opening over the width of the area to be coated, and an inlet opened in the tank below the outlet. The moving mechanism holds the tank such that the front end surface thereof faces the surface of the substrate, with a prescribed space, for example, 0.1 to 0.3 mm, therebetween. The moving mechanism moves the tank vertically relative to the substrate, from a start position to an end position, while the predetermined space between the tank and the surface is maintained. The front end surface of the tank has a lower edge positioned between the outlet and the inlet of the coating liquid outlet path.

  • Patent number: 5681392
    Abstract: A reservoir for dipping a non-cylindrical flexible belt into a coating fluid so that an electrophotographic layer can be deposited onto its outer surface during a manufacturing process includes a non-cylindrical tank with an inlet located at one end. A coating fluid enters the bottom of the tank and moves past a flow divider located inside or just above the inlet. This divides the entering fluid into two substantially equal portions, so that the level of coating fluid inside of the tank rises uniformly. The coating fluid passes first through a porous membrane, and then through a perforated plate, both of which will reduce the velocity of the coating fluid, to ensure that the fluid has laminar flow characteristics once it reaches the top of the reservoir. Finally, the coating fluid passes through an annular shaped flow director which ensures that the layer which is deposited onto the outer surface of the flexible belt has a uniform thickness.

  • Patent number: 5455062
    Abstract: A device for coating a plate has an open channel being open in an upward direction and a device for supplying a liquid to the open channel. The liquid in the open channel forms an convexly curved portion projecting upwardly from the open channel. A device for transporting a plate at a close distance past the open channel is provided, with which a surface to be coated of the plate facing the convexly curved portion of the liquid is guided such that a thin film of the liquid is deposited on the surface to be coated by adhesion effects. Another device for lacquering or coating plates or disks has a capillary slot that is filled with a liquid coating medium. The plate to be coated is advanced across the capillary slot with the surface to be coated facing downwardly so that due to the capillary effect a thin layer is deposited on the surface of the plate.
