Disclosed is a polycrystalline diamond or diamond-like element with greatly improved wear resistance without loss of impact strength. These elements are formed with a binder-catalyzing material in a high-temperature, high-pressure (HTHP) process. The PCD element has a body with a plurality of bonded diamond or diamond-like crystals forming a continuous diamond matrix that has a diamond volume density greater than 85%. Interstices among the diamond crystals form a continuous interstitial matrix containing a catalyzing material. The diamond matrix table is formed and integrally bonded with a metallic substrate containing the catalyzing material during the HTHP process. The diamond matrix body has a working surface, where a first portion of the interstitial matrix in the body adjacent to the working surface is substantially free of the catalyzing material, and a second portion of the interstitial matrix in the body adjacent to the working surface contains the catalyzing material. The first portion of the interstitial matrix and the second portion of the interstitial matrix have substantially the same impact strength.

A method, computer readable medium, and system for vapor deposition on a substrate that maintain a first assembly of the vapor deposition system at a first temperature, maintain a second assembly of the vapor deposition system at a reduced temperature lower than the first temperature, dispose the substrate in a process space of the first assembly that is vacuum isolated from a transfer space in the second assembly, and deposit a material on the substrate. As such, the system includes a first assembly having a process space configured to facilitate material deposition, a second assembly coupled to the first assembly and having a transfer space to facilitate transfer of the substrate into and out of the deposition system, a substrate stage connected to the second assembly and configured to support the substrate, and a sealing assembly configured to separate the process space from the transfer space. The first assembly is configured to be maintained at a first temperature and the second assembly is configured to be maintained at a reduced temperature lower than the first temperature.

The present invention provides a superhard polycrystalline diamond or diamond-like element with greatly improved resistance to thermal degradation without loss of impact strength. Collectively called PCD elements, these elements are formed with a binder-catalyzing material in a high-temperature, high-pressure process. The PCD element has a plurality of partially bonded diamond or diamond-like crystals forming at least one continuous diamond matrix, and the interstices among the diamond crystals forming at least one continuous interstitial matrix containing a catalyzing material. The element has a working surface and a body, where a portion of the interstitial matrix in the body adjacent to the working surface is substantially free of the catalyzing material, and the remaining interstitial matrix contains the catalyzing material. This translates to higher wear resistance in cutting applications, higher heat transfer capacity in heat sink applications, and has advantages in numerous other applications including hollow dies, indentors, tool mandrels, and wear elements.

The present invention receives list content providing location conditions in a list organized by location conditions in which a reference destination of location-dependent content, being content assigned correspondence to geographical location information, is compiled for each location condition, sent from a content communication server; receives the sent location information; generates area-specific list content comprising information on location-dependent content corresponding to location information, by extracting a list organized by location conditions, in which location conditions matching location information are provided, from the list content; and outputs the area-specific list content.

An SFP module includes a housing (1) and an ejector (70). An ejector seat (111) is formed in the housing for receiving the ejector. A triangular latch (114) is formed on the housing behind the ejector seat. The ejector includes a push bar (79) exposed forward of a front end (17) of the housing, and a tongue board (74). Two ejecting protrusions (741) are formed at a rear end of the tongue board, corresponding to a spring tab (611) of an SFP cage (6). The spring tab defines a retaining hole (613) for retaining the latch of the housing. When the SFP module is withdrawn from the cage, the push bar is pressed until the protrusions of the ejector have released the spring tab from the latch of the housing. The SFP module is then ejected from the cage by conventional spring means located in a rear of the cage.

The present invention provides a rotational magnetic gimbal with an integral magnetic bearing. Brushless DC motor technology provides electromagnetic suspension, using a single electromagnetic actuator to perform both the radial bearing and rotary torque (motoring) functions. An integrated motor and magnetic bearing consistent with the invention comprises a rotor comprising a plurality of permanent magnets and a stator comprising a plurality of independently controlled coil segments magnetically coupled to the permanent magnets. Embodiments may further comprise first and second radial position sensors, the first radial position sensor disposed in or adjacent to a clearance gap between the rotor and the stator for sensing the position of the rotor with respect to the stator along a first axis, and a second radial position sensor disposed in or adjacent to the clearance gap between the rotor and the stator for sensing the position of the rotor with respect to the stator along a second axis. In method form, a method for providing integral electromagnetic motor and bearing functions comprises sensing a first radial position of a rotor, the rotor comprising a plurality of permanent magnets, with respect to a stator along a first axis, the stator comprising a plurality of independently controlled coil segments magnetically coupled to the permanent magnets; and sensing a second radial position of the rotor with respect to the stator along a second axis; and delivering current to at least one coil segment, the amount of current based on at least one sensed position.

A lock bolt extendible and retractable by movement of a power transmission assembly driven by an actuator and having a cam thereon which cams against the lock bolt to retract the lock bolt and unlock the steering column. In some embodiments, the cam has a curved surface with varying distance from the axis of rotation of the cam or pivot to improved lock bolt motion. The cam can have a gradual ramp surface to extract a lock bolt even in binding conditions of the lock bolt.
