  • Patent number: 5534225
    Abstract: A chemical analysis element supplier has a cartridge container for storing a cartridge in which a plurality of chemical analysis elements are stored. The cartridge is inserted into the container through a cartridge insertion port which is formed in the top of the container. An element take-out mechanism takes out the chemical analysis element in the cartridge through an element take-out port which is formed in the bottom of the container. The element take-out mechanism is provided with a lifting member which is operative to move upward through the element take-out port to lift the cartridge in the container so that at least a part of the cartridge projects upward through the cartridge insertion port.

  • Patent number: 5518687
    Abstract: A chemical analysis film cartridge with a box-like casing body having first and second end walls opposed to each other between which a plurality of dry frameless chemical analysis film chips are stored in a stack. A first opening is formed in a side wall of the casing body near the first end wall so that only the film chip nearest the first end wall can be taken out of the casing body through the first opening by moving the film chip in a direction perpendicular to the stack. A second openings which permits a suction pad to hold the film chip nearest the first end wall and to remove it from the casing body through the first openings is formed in the first end wall. The width of the first opening is larger than the thickness of one film chip and smaller than double the thickness of one film chip over at least a portion of the first opening.

  • Patent number: 5317610
    Abstract: For the purpose of preventing reductions of wall thickness due to erosion-corrosion in parts (2, 3, 7) of a system made of carbon steel, and which constitute a wet steam system, a feedwater and condensate system, and a drain system of a thermal or nuclear power plant, a coating (17) of metal or ceramic which is chemically stable against a fluid flowing in the systems is formed by spraying on the surface of the devices which are exposed to the fluid.
