Problem: To provide a liquid-material discharge device that enables easier correction of a changed discharge amount during discharge operation than conventional techniques. Solution: A liquid-material discharge device according to the present invention, which includes a discharging member having a rod-shaped body, a liquid chamber wider than the discharging member, in which a tip portion of the discharging member is disposed, a discharge port communicating with the liquid chamber, a liquid feed path that makes the liquid chamber communicate with a liquid-material reservoir, and a driving device configured to drive the discharging member, includes a discharge amount adjustment member positioned at the liquid feed path, and a member position adjustment mechanism configured to shift a position of the discharge amount adjustment member within the liquid feed path, the discharge amount adjustment member being kept from interrupting communication between the liquid chamber and the liquid-material reservoir.

A dispensing apparatus for dispensing a fluid includes a dispenser body having a fluid chamber that receives the fluid, an outlet disposed on the dispenser body and that fluidly communicates with the fluid chamber, and a shaft disposed within the fluid chamber. The shaft at least partially defines a variable passage for the fluid to move therethrough from the fluid chamber to the outlet. The dispensing apparatus transitions between a plurality of dispensing configurations, and the variable passage is defined to have a different dimension for each of the plurality of dispensing configurations.

A composite friction unit of a three dimensional composite body is formed in a system for continuous process manufacturing of composite friction units. The system uses a plurality of rolls of reinforcing fiber fabrics, a resin dispensing system that receives a panel of reinforcing fiber fabric from each one of the rolls and separately dispenses resin through a plurality of dispensing tubes, each associated with a different panel, onto a surface of each panel. A forming die is positioned to receive the plurality of panels of reinforcing fiber fabric after resin is dispensed onto the panels and is configured to form a composite panel from the plurality of panels of reinforcing fiber fabrics. A cutting mechanism cuts a desired shape part from the composite panel.

The disclosure concerns a mixing valve for mixing two coating agent components (e.g. master batch and hardener) to form a multi-component mixture, with two coating agent inlets for supplying the two coating agent components and with two coating agent valves for controlling the coating agent flow through the two coating agent inlets, as well as with a coating agent outlet for discharging the multi-component mixture in a specific outflow direction. The disclosure provides that at least one of the coating agent valves is formed as a rotary slide valve having two plane-parallel valve discs which are rotatable relative to each other about an axis of rotation.
