Abstract: A high purity ceramic article having a typical pore size of at least about 15 ?m and an active impurity concentration of less than about 400 ppm can be prepared by molding ceramic powder, sintering to vaporize any active impurity components, washing to dissolve any remaining active impurity components with an acid solution, and oxidizing to remove any residual active impurity components.
Abstract: A cable clip for a connector housing is configured to route a plurality of cables within a server. The cable clip includes a backing, a first portion, and a second portion. The backing configured to be placed in physical communication with the connector housing. The first portion extends from a first edge of a first side of the backing, and has a first hook opposite the first side of the backing. The first portion is adapted to flexibly slide over the connector housing and snap fit the first hook around the connector housing. The second portion extends from a second edge of the first side of the backing, and has a third hook opposite the first side of the backing. The second portion is adapted to flexibly slide over the connector housing and snap fit the second hook around the connector housing.
Abstract: A method is provided for forming a contact toaster having a flexible belt. The method includes forming a flexible belt by applying at least one of a silicone rubber, a urethane rubber, and a fluoropolymer to a fabric reinforcement material having a first face and a second face, and forming ribs on the first face of the fabric reinforcement material. The ribs are formed from at least one of a silicone rubber, urethane rubber, and fluoropolymer. The flexible belt is attached to the contact toaster such that the ribs on the first face are configured to impart lateral force to objects to be toasted that are carried by the flexible belt. The flexible belt is attached such that it passes through a heating zone of the contact toaster.
Abstract: The disclosure is directed to a chemical mechanical polishing retaining ring including a polymer matrix and a filler including polyimide. The chemical mechanical polishing retaining ring has a wear rate performance not greater than about 75 microns/hour.
Abstract: A device comprising a first port, a second port, and a non-volatile memory. The first port is coupled to and accessible by a first module, and the second port is coupled to and accessible by a second module. The non-volatile memory of the device comprises a first memory portion and a second memory portion. The first memory portion is writable by the first port and write protected from the second port, and the second memory portion is writable by the second port and write protected from the first port.
Abstract: An integrated circuit includes first and second power supply voltage terminals, a voltage controlled oscillator (VCO), and a deep N-well field effect transistor (FET). The VCO has a first node coupled to the first power supply terminal, a second node, and first and second oscillator output terminals, at least one of which is coupled to a common pin. The deep N-well field-effect transistor (FET) has a first terminal coupled to the second node of the voltage controlled oscillator, a second terminal coupled to the second power supply terminal, and a control electrode to receive a power on signal, a deep N-well is coupled to the first power supply terminal and a P-channel is coupled to the second power supply terminal to form a high impedance electrostatic discharge path between the common pin and the first and the second power supply terminals through the deep N-well.
Abstract: A composite material including a thermoplastic polymer matrix and a non-carbonaceous resistivity modifier dispersed in the thermoplastic polymer matrix. The composite material has a surface resistivity of about 1.0×104 ohm/sq to about 1.0×1011 ohm/sq and at least a portion of a surface of the composite material has a surface roughness (Ra) not greater than about 500 nm.
Abstract: A mixer (114) includes a phase clock generator (404), a latch (420), and a multiplier (118). The phase clock generator (404) provides a plurality of phase clock signals. The latch (420) is coupled to the phase clock generator (404) via a first plurality of conductors (410) and provides a plurality of resynchronized phase clock signals. The multiplier (118) is coupled to the latch (420) via a second plurality of conductors (430) and mixes an input signal using the plurality of resynchronized phase clock signals to provide a mixed output signal. The second plurality of conductors (430) is characterized as having a lower end-to-end impedance than an end-to-end impedance of the first plurality of conductors (410).
Abstract: A receiver (200) includes a transconductance mixer (310), a polyphase filter (320), and a transimpedance amplifier (330). The transconductance mixer (310) mixes a radio frequency (RF) voltage signal into a current signal having a plurality of phases using a local oscillator signal. The polyphase filter (320) filters the current signal to provide a filtered current signal. The transimpedance amplifier (330) converts the filtered current signal into an output voltage signal.
