A valve device that can be activated by pilot air of comparatively low pressure though the size of such valve device is small and provides a valve device that is excellent in durability. The valve device comprises a pilot port which pilot air is supplied to activate a piston part, and a biasing means to press the piston part in the opposite direction to supply and discharge the pilot air, thus controlling the opening and closing of the valve. A first magnetic member is provided on a valve rod; a second magnetic member is provided on a housing. Magnetic attraction is generated between both magnetic members to activate the piston part in the first direction, thus increasing such magnetic attraction by the approach of both magnetic members. An arrangement-relation facing each magnetic member through an air gap is set even when making its closest approach.

A coating device is equipped with a rotary head, a drive unit, and an electric power supply unit. The rotary head is configured to be supplied with a coating material. The rotary head includes a diffusion surface that is configured such that the coating material is diffused toward an outer edge portion of the diffusion surface by a centrifugal force, and a plurality of groove portions that are included in the outer edge portion. The rotary head is configured to discharge a threadlike coating material from the groove portions. Also, the coating device is configured such that a diameter of the threadlike coating material is set equal to or larger than 0.03 mm and equal to or smaller than 0.1 mm and that the threadlike coating material is electrostatically atomized.

Coating device

A coating material filling and discharging device includes a coating material supply part configured to supply a coating material to a coating material storage bag arranged inside a case of a coating material cartridge, an extrusion liquid supply part configured to supply extrusion liquid to a surrounding region outside the coating material storage bag within the case, and store the extrusion liquid discharged from the case, an extrusion liquid route that connects an extrusion liquid supply part and the surrounding region with each other, a flowmeter provided in the extrusion liquid route, and a control part configured to determine whether or not filling of the coating material in the coating material cartridge is completed based on a drop of flow speed of the extrusion liquid.

Coating material filling and discharging device

A jet dispersing device includes a high pressure region having a flow inlet and a low pressure region having a flow outlet. A partition wall is positioned within the high pressure region such that the high pressure region is partitioned from the low pressure region. Additionally, the partition wall may be provided with at least one nozzle hole configured to jet a liquid from the high pressure region to the low pressure region such that the liquid is dispersed as fine particles. The partitioning wall may also have a cleaning fluid communication port having an opening area which is larger than an opening area of the at least one nozzle. Additionally, a valve mechanism configured to open and close the cleaning fluid communication port may also be provided.

Jet dispersing device

A small-sized and inexpensive coating material feeding apparatus capable of feeding even a coating material comprising less miscible main agent and curing agent as in an aqueous two component mixed coating material, while uniformly mixing them, to a coating machine or a coating material tank under extremely simple control, the apparatus comprising a measuring unit having a measuring cylinder for delivering the coating material ingredients each by an amount in accordance with the mixing ratio individually and simultaneously to the coating material tank, a storage unit having a transfer cylinder for storing the coating material prepared by mixing each of the coating material ingredients previously and then delivering the same to the coating machine or the coating material tank, and a valve unit formed with a switching valve for conducting channel switching, in which the coating material ingredients delivered from the measuring cylinder are pre-mixed in the channel stirring pre-mixer and a coating material delivered from the transfer cylinder is uniformly diffused and mixed in a jetting diffusion mixer.

A surface decorated article in which a surface is entirely or partially decorated with a coating of a first and second glitter paints each using a flaky glitter material as a pigment, wherein first paint particles at a low viscosity with a relatively high solvent dilution ratio formed by coarsely particulating a glitter paint and second paint particles at a high viscosity with a relatively low solvent dilution ratio formed by coarsely particulating a glitter paint are coated in a state mixed with each other, to form the coating comprising areas in which the first paint particles are dried to solidify and areas in which the second paint particles are dried to solidify are mixed together in a spotwise pattern. The surface of articles can be provided with colors or textures exhibiting unique and high quality feelings.
