摘要： A stationary die is held on the front surface of a stationary platen and a movable die is held on the front surface of a movable platen. A plurality of monitoring sections are set in advance within a moving range of the movable platen and an upper limit of forward thrust of the movable platen is set for each of the monitoring sections. When the forward thrust of the movable platen reaches the upper limit set in one of the monitoring sections during a die closing operation, it is determined that abnormality occurs to stop the movable platen from moving forward. If a die closing mechanism is of a toggle link type, the forward thrust of the movable platen is calculated based on the thrust of a crosshead which drives a toggle link mechanism, the moving speed of the crosshead, and the moving speed of the movable platen.

摘要： This invention provides a method which makes it possible to reliably detect malfunctions during the ejecting step without rendering the injection molding machine more complicated. An ejector pin is incorporated in the movable die. This ejector pin is connected, via an ejector plate, a connecting rod, a connecting plate and a feed screw, with a servo motor. The force for ejecting the ejector pin pushing a molded product is measured from the driving torque of a servo motor. In this invention, the relationship between driving torque and elapsed time from the initiation of ejection of the molded product is stored as a reference pattern. The tolerance limit and monitoring interval of driving torque are preset relative to the reference pattern. When the value of driving torque falls outside the tolerance limit during the ejecting step, it is judged as a malfunction, and an alarm is generated to stop the machine in a safe state.

摘要： A wireless network communication system and method in which the wireless channel can be determined by selecting a vacant pseudonoise (PN) or spreading code. When communication is started, in order to judge whether a PN code is being employed by another communication group, the degree of correlation between the received signal converted to an intermediate frequency or a base-band frequency by a transceiver and a reference pseudonoise code signal is detected using a correlation circuit within a correlation detector. There is a channel controller which controls the PN code used by the communication terminal which receives an output of the correlation detector which correlates a received channel signal with a reference PN code generated by the PN code generator. If the correlation output signal is not smaller than a threshold value, it is determined that the PN code is to be employed. Furthermore, at the time of transmission, the pseudonoise code generator is controlled so as to supply the selected PN code to a transceiver. The transceiver combines the data to be transmitted with the PN code to be used in order to determine the final signal which is to be transmitted by the terminal.
