A sliding structure for high load and having high strength as well as sufficient lubricating performance, wherein a solid lubricating material is buried in a sliding surface, an oil reservoir of a predetermined capacity is formed on the reverse of the surface; oil supplying pores extend from the oil reservoir to the sliding surface; and a continuous pore material inserted into the oil supplying pore which provides a limited supply of oil to the sliding surface concerned.

Sliding structure for a high load

A method and system is described for sensing an abnormality in a degassing flow path of a vacuum die casting machine. When a vacuum device is operated to degas a gas in a cavity of a mold, a gas speed flowing through a piping is detected. The gas speed thus detected is compared with the predetermined maximum proper air speed value to determine whether the maximum gas speed value falls into the tolerance limits of the maximum proper air speed value or not. In this comparison, when the detected value departs from the tolerance limits, it is regarded that a clogging has occurred in the degassing system and an alarm is issued.
