  • Patent number: 4988744
    Abstract: An aromatic composition comprises aromatic substances that are encapsulated and/or clathrated in a matrix of polymer. The polymer includes an inorganic polymer produced from metal alkoxides; a conjugated polymer produced from metal alkoxides and silane coupling agents; and a conjugated polymer produced from metal alkoxides, silane coupling agents, and organic monomers. The aromatic composition has slow-release characteristics, so that the aromatic substances are released over a long period of time. In a method for the production of the aromatic composition, a catalyst for sol-gel methods that comprises an acid or its anhydride and an organic base, and if necessary, irradiation with ultraviolet light and/or an electron beam are used for making the polymer.

  • Patent number: 4830882
    Abstract: Paint spray guns are cleaned in respective cleaning tanks. In each of the cleaning tanks, a cleaning fluid is ejected to the nozzle end of the paint spray gun by a plurality of cleaning guns disposed in the cleaning tank. The paint spray guns and the cleaning tanks are relatively movable so that the cleaning tanks are retracted away when the paint spray guns spray a paint coat over a desired object such as a vehicle body. Each of the cleaning tanks includes two flexible cover members having holes for inserting the paint spray gun therethrough. The cover members and the inserted paint spray gun close a cleaning chamber defined in the cleaning tank to prevent the cleaning fluid from leaking out. Each cleaning tank comprises a base plate and a casing detachably mounted on the base plate and defining the cleaning chamber.

  • Patent number: 4766379
    Abstract: A main magnetic field is applied to a target to excite the nuclear spin of a chosen type of atoms in a selected slice of the target. Subsequently, first and second gradient fields, which are parallel to the main magnetic field noted above and the strengths of which vary in the directions of respective first and second crossing axes in the slice, are applied to the target for predetermined period of time. Then, a readout magnetic gradient field, which is parallel to the first gradient field, and the strength of which varies in the direction of the first axis, is applied to the target to detect a free induction signal from the target. The detection of the free induction signal is repeatedly performed with a plurality of different strengths of the first and second gradient fields, whereby NMR data containing chemical shift data is obtained from the slice of the target noted above.
