Disclosed is a method for forming a hollow pipe-sandwiching metal plate and applications thereof. The hollow pipe-sandwiching metal plate comprises a first panel, a second panel, and multiple hollow pipes between the first panel and the second panel; gaps are arranged among the hollow pipes, and the hollow pipes are connected to the first panel and the second panel by brazing. The present disclosure further includes the applications of the hollow pipe-sandwiching metal plate. The hollow pipe-sandwiching metal plate has advantages, such as light weight, high strength, low stress, high temperature resistance, pressure bearing, thermal insulation and vibration isolation. The metal plate will not deform due to thermal difference, thereby providing permanent service life of the metal plate.

A computer readable medium having instructions is provided. When executed by a computer system, the instructions direct the computer system to identify a control element used to control a process in a machine automation environment, identify a plurality of variables used by the control element to monitor the process, and translate the plurality of variables to a plurality of aliases according to a translation protocol specific to the control element.

An interface for an industrial controller is provided that enables connection of different types of plug-in I/O modules to the industrial controller. The interface includes several mechanisms, which can be implemented through control logic, circuitry, and/or software, that enable the control/monitoring device to operate in conjunction with different types of plug-in I/O modules. According to certain embodiments, the interface includes setup mechanisms that enable initial communications between the plug-in I/O modules and the control/monitoring device. The interface also may include operational mechanisms that facilitate communication between the plug-in I/O modules and the control/monitoring device during operation. The interface further may include registers that store data for the plug-in I/O modules.
摘要:
This relates to detecting unwanted couplings between a protected terminal and other terminals in an integrated controller of a power supply. Offset and clamp circuitry may apply a positive or negative offset voltage and clamp current to one or more terminals of the controller. In the event that a terminal having the offset voltage and clamp current is accidentally coupled to the protected terminal, the offset voltage and clamp current may be applied to the protected terminal. The protected terminal may be coupled to a fault detection circuitry operable to detect a fault signal at the protected terminal. The fault detection circuitry of the controller may cause the power supply to shut down in response to a detection of the fault signal at the protected terminal or may cause the power supply to shut down in response to a detection of a predefined threshold number of cycles in which the fault signal is detected.
摘要:
Wire is fed to a bonding tool of a wire bonder by a pneumatic device that is operative to urge the wire to feed through an outlet of the pneumatic device towards the bonding tool. A wire clamp is located adjacent to the outlet of the pneumatic device and a wire guider with a hole is located adjacent to the wire clamp between the wire clamp and the bonding tool for threading the wire through the hole before being fed to the bonding tool.

摘要:
A method to reduce or eliminate pinch flashing in mold operations by applying a thin coating of a hydrocarbon wax to the outside surface of an uncured rubber article or on the sidewall or shoulder of a green tire at a location(s) where segments of the mold close on each other and on the rubber article or tire during cure. The hydrocarbon wax has a melting point from about 60 degrees to about 80 degrees Celsius, and is compatible with the composition of the rubber. The hydrocarbon wax acts as a sacrificial layer and is scraped up by the mold parts instead of the rubber when the mold segments close.
