Patent CA-2572397-A1 (CA)
Inventor: FANG YI
IPC: C30B29/04
Filed: 2006-12-20
Abstract: Polycrystalline ultra-hard materials and compacts comprise an ultra-hard material body having a polycrystalline matrix of bonded together ultra-hard particles, e.g., diamond crystals, and a catalyst material disposed in interstitial regions within the polycrystalline matrix. The material microstructure is substantially free of localized concentrations, regions or volumes of the catalyst material or other substrate constituent.  The body can include a region extending a depth from a body working surface and that is substantially free of the catalyst material. The compact is produced using a multi-stage HPHT process, e.g., comprising two HPHT process conditions, wherein during a first stage HPHT process the catalyst material is melted and only partially infiltrates the precursor ultra-hard material, and during a second stage further catalyst material infiltrates the precursor ultra-hard material to produce a fully sintered compact.

Filed: 2005-07-06
Abstract: A first and a second object (1 and 2) are joined with the aid of a joining element (8) comprising at least in the region of its distal and proximal ends (8.1 and 8.2) a thermoplastic material. Two blind holes (5 and 6) facing each other are provided in the two objects (1 and 2) and the joining element (8) is positioned in the blind holes such that its distal and proximal ends (8.1) are in contact with the bottom faces of the blind holes and such that there is a gap (9) between the two objects (1 and 2). This assembly is then positioned between a support (3) and a sonotrode (4). The sonotrode (4) and the support (3) are forced towards each other, while the sonotrode (4) is vibrated, thereby liquefying at least part of the material having thermoplastic properties, there, where the joining element ends (8.1 and 8.2) are pressed against the bottom faces of the holes (5 and 6) and allowing the liquefied material to infiltrate into pores of the hole surfaces or unevennesses or openings provided in the hole surfaces, such anchoring the joining element ends (8.1 and 8.2) in the objects (1 and 2). For achieving suitably similar anchorage qualities at the two joining element ends (8.1 and 8.2), the distal end (8.1) of the joining element (8) has a smaller face area and comprises less thermoplastic material than the proximal end (8.2) of the joining element.

Inventor: POTTEIGER DAVID
IPC: G06F3/06
Filed: 2005-07-12
Abstract: A system and method is disclosed for improving data integrity and the efficiency of data storage in separate memories of a computing device. In particular, the present invention introduces a combination of two types of memory, namely, an NVRAM and a Flash memory, as persistent memory for storing file data. By constantly caching a last data portion of a data file in an NVRAM, it avoids any sector erasing for individual bits in a Flash memory. Such an approach increases the data storage efficiency and life expectancy of a Flash memory. The present invention has very broad application in almost all computing devices, including any PC (desktop or laptop) and server computers. It demonstrates particularly advantageous performance in portable electronic devices implementing Windows(TM) CE operating systems.
