  • Patent number: 6402058
    Abstract: An aerosol spray gun used selectively in two spraying modes of small and large patterns is provided. The aerosol spray gun has a throttle valve, an air duct, and a coupling link. The throttle valve has an internal air duct for supplying pressurized air to a patterning air outlet which shapes a paint spraying stream jetted out from the aerosol spray gun, and has a movable valve element to which a compressed spring applies force to open the valve. The air duct created at the tip of the movable valve element supplies a small volume of air from the internal air duct to the patterning air outlet while the movable valve element seats on a valve seat. The coupling link, coupling the movable valve element to the trigger, has an elongated hole to disconnect the trigger from the movable valve element without cooperative relation between them from an initial stage where an operator begins to squeeze the trigger to an intermediate stage before the operator fully squeezes the trigger.

    Abstract: A liquid crystal device is constituted by a pair of substrates having mutually opposing electrodes thereon, and a liquid crystal layer disposed between the substrates so as to form a pixel comprising a pair of the opposing electrodes and the liquid crystal layer therebetween. The liquid crystal layer in a pixel is divided into a plurality of regions having mutually different liquid crystal layer thicknesses, and the pixel is constituted so as to show an applied voltage-transmittance characteristic having an improved linearity. More specifically, for example, the liquid crystal layer in a pixel is provided with locally varying thicknesses by forming on a substrate pluralities of stripe-shaped projections and indentations at locally different indentation widths so that the projections have a smaller width in a region having a smaller indentation width than in a region having a larger indentation width.
