摘要:
To eliminate a temperature overshoot or an undershoot during thermocontrol of thermocontrolled components, e.g. an injection cylinder, with respect to an object temperature in each operating status of the injection molding machine, the Fuzzy Control theory is used for controlling the injection molding machine. By using the Fuzzy Control theory, the object temperature of the thermocontrolled components can be attained with practically eliminated overshoot and undershoot.

A main frame for a C-type frame for die tightening units mounted for an injection molding machine is prepared by employing a casting process. The main frame includes an opposing pair of side frames, upper frames projecting forward of fore upper surfaces of the side frame and a front frame extending between both the side frames. The side frames, the upper frames and the front frame are cast and integrated with each other to form the main frame having a predetermined width. A base board made by casting or made of a steel plate is bolted to the lower end of the main frame to form a C-type frame, and a pair of support columns each made of a steel material extend through the joint portions where the side frames are integrally joined to the front frame. The tensile strength and the compressive strength of the C-type frame are increased by tightening the support columns via nuts threadably engaged with male threads machined at the opposite ends of each support column. With this construction, the C-type frame can be constructed with lighter weight and smaller dimensions.

An encrypted-traffic discrimination device includes an input interface, a flow discrimination section, a data accumulation section, a selective data calculation section, a calculation result determination section, and an output interface. The flow discrimination section discriminates the input traffic into separate flows based on at least a transmission origin address and a transmission destination address. The data accumulation section accumulates characteristic amount data of the traffic for each of the separate flows. The selective data calculation section executes an evaluation computation utilizing specific data from the characteristic amount data. The calculation result determination section that, based on a calculated evaluation computation value, executes threshold value determination to determine whether or not the traffic is encrypted, and, if the traffic is determined to be encrypted, which encryption format the traffic is encrypted with.
