  • Liquid flow controlling system
    Patent number: 5058636
    Abstract: By employing two independent, separate and distinct flow paths which are controllably sequentially opened during use in a single actuation operation, an error-free, spill-free flame and explosion proof liquid delivery/filling system is achieved. In the preferred embodiment, both flow paths are normally maintained in a closed, sealed configuration, requiring an actuation force to controllably, sequentially open the flow paths. In addition, by providing a cooperating, mating liquid transfer assembly, the container on which the liquid delivery/filling system is mounted can be refilled with safety and ease, completely eliminating spillage of the liquid. In this way, a fully integrated, cooperating, liquid flow controlling system is realized.

  • Varnish impregnation method and apparatus
    Patent number: 5056457
    Abstract: Apparatus is provided for carrying out a varnish impregnation method wherein a sheet-like base material is sequentially passed through a low-viscosity liquid storage region storing a low-viscosity liquid such as a solvent, a thermal syphon region, and a varnish storage region storing a varnish, the thermal syphon region being positioned between the low-viscosity liquid storage region and varnish storage region and communicating with both regions at air tight seals closed by liquid surfaces, and heating the base material in the thermal syphon region to vaporize the low-viscosity liquid impregnated in the base material. When the base material passes through the low-viscosity liquid, air contained in the base material is replaced with the low-viscosity liquid and discharged outside the apparatus. The low-viscosity liquid impregnated in the material is vaporized in the thermal syphon region.

  • Apparatus for positioning a pick-up coil for detecting magnetic flux quantum trapped in a superconductor
    Patent number: 5053707
    Abstract: A head with a pick-up coil is attached to a supporter so that the head is freely movable along the direction perpendicular to the surface of a superconductor. Fluid spouted from the spout hole of the head maintains the height (gap space) of the head from the surface. The head is firmly fixed to the supporter in the direction along the surface. Since the relative position of the head in the direction along the surface of the superconductor is changable by drive means for moving the superconductor or the head, the distribution of the magnetic flux which is trapped in the superconductor is measured by scanning the surface of the superconductor with pick-up coil.

  • Grid-inserted quantum structure
    Patent number: 5054030
    Abstract: A grid-inserted quantum structure which exhibits a quantum size effect and in which a material (3), (4) dissimilar to that of a confining layer (1) having a high level of electron affinity is disposed on both sides or one side of the confining layer (1), comprises grids (2) which are composed of a dissimilar material having an attraction potential or a repulsion potential and which are disposed at equal intervals. This structure enables electrons to be captured in regions without the grids (2) or around the grids (2) owing to the interaction between the electrons and the grids (2) in the confining layer (1). Further, the effective function of the potential of the grids (2) enables the same effect as that obtained by several tens atomic layers of a dissimilar material to be obtained by one or several atomic layers.

  • Preparing metal for melt-coating
    Patent number: 5053112
    Abstract: Steel is prepared for hot-dip coating in molten zinc, by forming lead chloride on it in a greater mass (at least 12 g/m.sup.2) than possible by evaporation from saturated aqueous solution. One way of so forming the lead chloride is to cathodize the steel (24000 coulomb/m.sup.2) in 1:1 HCl saturated with lead chloride, and air-dry the steel. The steel thus prepared is dipped for 2 minutes in molten zinc or, for greater corrosion resistance, in molten scrap zinc.

  • Adjustable intra-luminal valvulotome
    Patent number: 5049154
    Abstract: An adjustable intraluminal valvulotome including a hollow tubular member in which is slidably disposed a control wire. First and second spring wire elements respectively interconnect first and second cutting blades having first and second perpendicular cutting edges to one end of the control wire. There is a handle member proximate the other end of the control wire for controlling longitudinal movement of the control wire in and out of the tubular member. The handle member enables the first and second cutting blades to move from a first extended cutting position to a second retracted position. A receptacle at the distal end of the tubular member restrains the cutting blades in a fully retracted non-cutting position and prevents their engagement with the vein or valves. A method of using a valvulotome to rupture and render inoperative the valves is also disclosed.
