First to eighth laser measurement sections (30a) to (30h) of a laser measurement unit (30) measures a height of a surface of powder resins (15) in a coil insertion range CA for every angular degree in a circumferential direction of a stator core (2). A control unit (18) computes the number of points where the height of the surface is lower than a predetermined height among measurement results at multiple points measured by the first to eighth laser measurement sections (30a) to (30h), where the number of points is defined as an index value indicative of a dispersion of the measurement results. When it has been determined that the index value exceeds a first predetermined value, a notification is issued by outputting from a speaker (32) a sound indicative of the fact that the index value that has been computed exceeds the first predetermined value.

A method removes a follower plate of a device for transporting viscous material out of a barrel-like container. The device has the follower plate for closing the container, which is open at the top and has a container base and a container casing extending upwards from the base, the follower plate being movable toward and away from the base. A force measuring sensor measures a force exerted by a container onto a placement surface; the controller switches the ventilation mode to the lifting mode if the force exerted by the container onto the placement surface exceeds a first target force value; and the controller switches the lifting mode to the ventilation mode if the force exerted by the container onto the placement surface falls below a second target force value, and/or the at least one sensor measures the position of the container relative to a stationary point.

A device for measuring and regulating a volume of a fluid dispensed by a time-pressure dispenser, the device comprising: an adaptor for releasably coupling a syringe to the device, the syringe containing a fluid to be dispensed; a probe configured to be coupled with a piston of the syringe, the piston being operative to apply a pressure for ejecting the fluid from the syringe upon the application of an air pressure to the piston; and a displacement detector operative in use to determine a position of the probe so as to determine a position of the piston when dispensing the fluid, whereby to regulate the volume of the fluid dispensed from the syringe.

A fluid pressure-feed device includes a main tank and a sub tank. The sub tank is connected integrally with an upper portion of a main follower plate that applies pressurizing force to a urethane adhesive inside the main tank. A drum pump is provided in an upper portion of a sub follower plate provided in the sub tank. While the urethane adhesive is flowing into the sub tank from the main tank, the urethane adhesive is fed under pressure from the sub tank to a fluid passage by actuation of the drum pump. While the main tank is being replaced, the urethane adhesive inside the sub tank is fed under pressure to the fluid passage by the drum pump.
