In order to allow a worker to accurately and repeatedly mark an original plan on a working surface, the present disclosure provides a nonrestrictive drive-type marking system comprising a nonrestrictive drive-type marking device, the nonrestrictive drive-type marking system including an input unit configured to receive data of content to be marked; a marking unit configured to mark the content corresponding to the data on a working surface; a driving unit configured to allow at least a part of the nonrestrictive drive-type marking device comprising the marking unit to nonrestrictively move on the working surface; a position detecting unit configured to sense position information of the nonrestrictive drive-type marking device; and a control unit electrically connected to the input unit, the marking unit, the driving unit, and the position detecting unit, and configured to calculate a current position of the at least the part of the nonrestrictive drive-type marking device comprising the marking unit by comparing the position information with the data, to compare the current position with the data, and if the current position does not match with the data and a degree of mismatch thereof is within a preset range, to move at least a part of the marking unit, and to control the nonrestrictive drive-type marking device to mark the content corresponding to the data on the working surface while the nonrestrictive drive-type marking device moves.

Provided are an oil-based ink composition for writing utensils, a writing utensil using the same, and an airbrush unit using the same. The oil-based ink composition for writing utensils has good writing properties on writing surfaces of various materials and improved scratch resistance to scratches repeated or to scratches with stronger force on a marking after writing. The subject oil-based ink composition for writing utensils contains at least an aluminum pigment, a colorant, a resin, an organic solvent, and a polydimethylsiloxane, the polydimethylsiloxane having polyether-modifying groups at both ends, and a total number of hydroxyl groups on the polyether-modifying groups being 3 or greater.

A device for marking a surface, the device comprising: a body configured to store a marking substance; a guide arrangement having a first end and a second end, at least a portion of an outer surface of the guide arrangement tapering from the first end to the second end which is narrower than the first end, wherein an output path is provided through the second end at substantially the center of the guide arrangement; an activation arrangement; and a delivery arrangement which is configured, in response to triggering of the activation arrangement, to deliver a quantity of the marking substance from the body, along the output path and out of the second end, wherein, in use, a user inserts at least the second end of the guide arrangement into an aperture in an element positioned adjacent a surface until the outer surface of the guide arrangement contacts the aperture, and the user triggers the activation arrangement to deliver a quantity of the marking substance through the second end and onto the surface to mark the surface at a position which is substantially aligned with the center of the aperture.

This device comprises a control panel (23) in which said representation is digitally stored, a platen (9) of flat shape designed to accept a support, such as a sheet of paper, an airbrush printing tool (7) designed for airbrush printing (7), comprising a hopper and a reservoir (21) designed to take ash and ink that are to be mixed by the hopper, the airbrush printing tool (7) being designed to be able to create airbrush prints using the mixture contained in the reservoir and supplied by the hopper, the airbrush printing tool (7) furthermore being mounted with the ability to move relative to the platen (9) along three orthogonal axes and being numerically controlled into its positions along the three axes by the control panel (23) so as to allow the digital representation to be airbrush printed onto the support.

A marking/drying tool applies ink to biological tissue using a single handheld device. A cylindrical body retains a felt tip movable between a retracted position within the body and an extended position outside the body for marking the tissue. A gas source has a manual valve to selectably dispensing a drying gas onto the tissue. In a preferred embodiment, an interlock prevents dispensing of drying gas when the tip is in the extended position and prevents the tip moving to the extended position when the manual valve is dispensing the drying gas.

A liquid applying tool which can create pressurizing action with a simple structure and without any labor at the time of using the liquid applying tool, and allows liquid to be smoothly fed to a tip end of a liquid applicator member with the assistance of the pressurizing action.

Provided is an airbrush in which a needle cap separated from a nozzle is not easily lost. The airbrush includes: an airbrush body; a nozzle that is provided at a tip of the airbrush body so as to spray paint and air; a needle cap that is separably attached to the nozzle; and a needle cap attachment portion that is provided at a rear end of the airbrush body so as to temporarily attach the needle cap separated from the nozzle thereto.

An oil-based ink composition suitable for writing utensils may contain an aluminum pigment of the non-leafing type, a solvent, and a resin. The surface of the aluminum pigment is an embossed scale-like aluminum pigment of the non-leafing type that expresses interference fringes. The arithmetic mean roughness Ra of a coating film measured under the condition of a measurement range of 2 mm in conformity with JIS B 0601 is 250 or more. The coating film may be formed by applying such a oil-based ink composition to a polystyrene plate to a thickness of 50 m and drying.
