  • Publication number: 20160076811
    Abstract: A droplet removal apparatus comprises a first liquid-scraping unit and a second liquid-scraping unit which are displaced from each other in an up-down direction along a movement direction of the optical film and arranged, respectively, on right and left sides across the optical film. Each of the first and second liquid-scraping units comprises a liquid-scraping member for scraping off the droplets, and a liquid-scraping member holding mechanism comprising a pressing-side holding member, a support-side holding member having a pair of angle adjustment shafts provided, respectively, at longitudinally opposite ends thereof to protrude outwardly. The pressing-side holding member and the support-side holding member are detachably fastened together in such a manner as to cooperatively hold the liquid-scraping member.

  • Patent number: 5478520
    Abstract: A process and apparatus for effecting injection molding of plastic resin products on an injection molding apparatus including a metal mold composed of a slidable mold element and a fixed mold element defining together the mold cavity, an actuator for sliding the slidable mold element and an injection nozzle for adjusting the nozzle flow path section, which comprises a first molding step of injecting a molten resin into the mold cavity which has been preset by the slidable mold element so as to include a post-compression margin to be compressed afterwards in a second molding step, to effect the injection under a reduced molding pressure, while causing a temperature elevation and, thus, a viscosity reduction of the molten resin, until the mold cavity has been filled up, and a second molding step of compressing the resin so charged in the mold cavity by operating the slidable mold element to compress the charged resin to compensate the post-compression margin, so as to allow an effective pressing force to be imp

  • Patent number: 5246949
    Abstract: (A) a diacylated dopamine derivative represented by the formula (I): ##STR1## wherein R.sup.1 represents an alkyl group having 3 to 7 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms, substituted or unsubstituted phenyl group or a substituted or unsubstituted nitrogen-containing heterocyclic group; and R.sup.2 represents a hydrogen atom or a lower alkyl group; or a salt thereof; and(B) one or more compounds selected from lactic acid esters, fatty acid monoglycerides and higher alcohols; optionally together with(C) an unsaturated fatty acid monohydric alcohol ester. This preparation has a sustained effect, a high skin permeability and a low skin irritativeness.

  • Patent number: 5098275
    Abstract: The invention is embodied as a raw material resin feeding apparatus for a molding machine, such as an injection molding machine or an extruder. In this system, upon carrying out a variable resin-change operation by making use of material to be changed, raw material resin is intermittently fed to a feed section by intermittently opening and closing a resin passageway. The improvements reside in that the apparatus includes a raw resin material feed selection mechanism provided midway along a resin passageway for selectively either feeding a predetermined amount intermittently or continuously to a feed section. A resin-change resin feed start detector mechanism is provided for detecting completion of discharge of the amount of raw material corresponding to the predetermined amount, and a resin-change completion detector mechanism is provided. With this apparatus, raw material can be selectively fed to effect quick resin-change or for normal operation.

  • Patent number: 4037930
    Abstract: In a liquid crystal display cell wherein two glass plates are sealed to a peripheral sealing member provided with a liquid crystal inlet port, the peripheries of the glass plates generally project slightly beyond the periphery of the peripheral sealing member thus forming a shallow groove. Low melting point glass filler is filled in the groove about the inlet port. A metal layer is applied onto the filler and finally a solder layer is applied onto the metal layer to seal the inlet port.
