Abstract: In production management systems, management devices includes a management device of a pre-process which adds a hash value of a production condition information received from a preceding process and a hash value calculated from the production condition information of the pre-process to calculate a first hash value and transmit the production condition information of the pre-process and the first hash value to a management device of a current process, and the management devices includes a management device of a current process which calculates a second hash value from production condition information received, calculates a third hash value obtained by subtracting the second hash value from the first hash value.

Abstract: A viscous liquid feed nozzle has a nozzle body having a thin and long hole with a front end serving as a feed port. The nozzle is used with a viscous liquid feed unit to feed a viscous liquid such as a viscous adhesive from the feed port. The nozzle has a lubricative plated layer at least on the inside and outside of the feed port. The lubricative plated layer is formed by electroless plating by immersing the nozzle in a plating tank containing a lubricative plating solution. A base end of the nozzle body may have a wide port. In this case, the lubricative plated layer is formed by immersing the nozzle body in the plating tank containing the lubricative plating solution so that the lubricative plating solution enters the wide port and by applying pressure or gravity to the lubricative plating solution in the wide port to pass the lubricative plating solution through the thin and long hole of the nozzle body and discharge the same from the feed port. The viscous liquid feed nozzle with the lubricative plated layer is capable of stably feeding a very small quantity of a viscous liquid.
