A system for forming a particle layer on a substrate may include at least one sprayer and at least two masks configured to selectively mask a substrate in a first region and second region of the substrate. The at least one sprayer may be configured to spray particles at the substrate, where the at least two masks maintain the first region and second region substantially free of the deposited material. A heater may be employed to heat the substrate as the particles are sprayed by the at least one sprayer onto the substrate.

A powder film forming method includes the steps of: filling an opening with a powder, the opening being formed in a screen plate; and forming the powder film by generating an electric potential difference between the screen plate and a substrate so as to cause the powder, which is filling the opening, to move to the substrate.

The supply unit is used in a printing device including a printing head configured to perform printing process of a viscous fluid on a printing target using a screen mask, a collection section having a collection member configured to contact the screen mask to collect and move the viscous fluid and a collecting and moving section configured to move the collection member in a predetermined printing direction. The supply unit includes a supply section having a mounting section capable of mounting and dismounting a cartridge accommodating the viscous fluid, a driving section configured to move the supply section in the supply operation direction, a detection member, and a supply section detecting section configured to detect whether the supply section is positioned in a passage space where the collection section and the supply section do not contact each other by the position of the detection member.

A screen-printing apparatus for repeatedly marking an indicium at regularly spaced intervals or predefined discrete intervals on a surface or medium. The screen-printing apparatus includes a wheel mounted to a housing. A screen frame can be mounted to a housing that can interchangeably receive a screen having void(s) of a shape that corresponds to the indicia to be printed. The screen-printing apparatus also has an ink supplying unit that sprays ink over the top surface of the screen. A solenoid operably coupled to the ink supplying unit for triggering the ink supplying unit. The solenoid and the wheel are operably coupled to a control unit, the control unit can receive readings from the wheel about the distance covered by the wheel on the surface and based on the readings can trigger the solenoid at predefined intervals.
