A method of pressing a powder metal compact comprising partially filling a die cavity with powder metal, engaging a second die with the first die, extending radially inwardly punches for forming a transverse feature in the compact, filling the die cavity with powder metal, compressing the powder metal with a punch, relieving pressure on the compact, withdrawing the radially inwardly punches so as to allow axial movement of the compact, withdrawing the second die, and ejecting the compact from the die while simultaneously filling the die cavity.

This invention relates to a device to compact parts with an undercut out of powder material having an upper die moveable relative a lower die, at least one upper punch associated with the upper die for relative movement therebetween, at least two lower punches associated with said lower die for relative movement therebetween, the lower punches defining a lower cavity with the lower die for filling with the powder material when the dies are in an open position, the upper die contacting the lower die in a closed position for movement of one of the lower punches towards the upper die so as to transfer the powder material towards the upper die and then to compact the powder material between the upper and lower punches with said dies in the closed position so as to produce said part; said dies moveable to an eject position for ejection of the compacted part.
摘要:
A method and system for cleaning a substrate in a multi-module cleaning assembly is provided. The method begins by receiving the substrate into the cleaning module. A cleaning chemistry, at a temperature elevated from an ambient temperature, is applied onto a top surface of the substrate. Concurrent with application of the cleaning chemistry, vapors are exhausted from the cleaning chemistry through a port located below a bottom surface of the substrate with the vapor exhaustion providing a negative pressure relative to a pressure external to the cleaning module. The application of the cleaning chemistry is terminated, followed by termination of the exhausting of the vapors. The substrate is dried after the flowing of inert gas is terminated.

A composition is described which consists of a microemulsion of oil in a water/glycol solution containing certain thickening agents, emulsifiers, substantially water-insoluble, partially polar oils, and alkanolamines to provide the desirable viscosity and shear stability needed to give a composition having effective de-icer and anti-icing properties.

This invention relates to a device to compact parts with an undercut out of powder metal, including a pair of dies linearly moveable relative to one another and then phased, and an associated linearly displaceable pair of punches to produce said parts with said undercut.

The transmission connector includes a base, a flexible circuit board and a cover. The base has a fixing seat with bendable tongues and a receiving seat. The flexible circuit board is received in the fixing seat and the receiving seat with abutting against the tongues. The cover includes a contact seat coupled to the fixing seat and having insulation-displacement contacts (IDCs). Bottoms of the IDCs are in contact with the flexible circuit board. The tongues generate elasticity force to push the flexible circuit board, so that the flexible circuit board can keep in electric contact with the IDCs.

摘要:
Methods for cleaning a substrate are provided. One such method includes receiving the substrate into a cleaning module and flowing an inert gas into the cleaning module. The flowing of the inert gas includes flowing the inert gas into an inlet defined within a top surface of the cleaning module and modifying a direction of the flowing inert gas to flow radially along the top surface of the cleaning module. Concurrent with or after initiating the flowing of the inert gas, a cleaning chemistry is introduced onto a surface of the substrate. The cleaning chemistry is at a temperature elevated from an ambient temperature. The dispensing of the cleaning chemistry is terminated and the flowing of the inert gas is terminated either concurrent with or after termination of the dispensing of the cleaning chemistry. The substrate is dried after the termination of the flowing of the inert gas.
