摘要： A physical vapor transport growth system includes a growth chamber charged with SiC source material and a SiC seed crystal in spaced relation and an envelope that is at least partially gas-permeable disposed in the growth chamber. The envelope separates the growth chamber into a source compartment that includes the SiC source material and a crystallization compartment that includes the SiC seed crystal. The envelope is formed of a material that is reactive to vapor generated during sublimation growth of a SiC single crystal on the SiC seed crystal in the crystallization compartment to produce C-bearing vapor that acts as an additional source of C during the growth of the SiC single crystal on the SiC seed crystal.

摘要： In one embodiment of the present invention, storing a plurality of key value pairs may be accomplished by first, for each of two or more quantities of most significant bits, determining how much overall memory usage will be saved upon removal of the corresponding quantity of most significant bits from each key in the plurality of key value pairs. Then, for the quantity of most significant bits determined to have the most overall memory usage savings, the quantity of most significant bits may be removed from each key in the plurality of key value pairs. Then a first auxiliary data structure may be formed, wherein the first auxiliary data structure contains the removed quantity of most significant bits from each key in the plurality of key value pairs and pointers to the remaining bits of each key of the plurality of keys in a primary data structure.

摘要： In a crystal growth method, a seed crystal 8 and a source material 4 are provided in spaced relation inside of a growth crucible 6. Starting conditions for the growth of a crystal 14 in the growth crucible 6 are then established therein. The starting conditions include: a suitable gas inside the growth crucible 6, a suitable pressure of the gas inside the growth crucible 6, and a suitable temperature in the growth crucible 6 that causes the source material 4 to sublimate and be transported via a temperature gradient in the growth crucible 6 to the seed crystal 8 where the sublimated source material precipitates. During growth of the crystal 14 inside the growth crucible 6, at least one of the following growth conditions are intermittently changed inside the growth crucible 6 a plurality of times: the gas in the growth crucible 6, the pressure of the gas in the growth crucible 6, and the temperature in the growth crucible 6.

摘要： The instant invention comprises a hydroprocessing method having at least two stages. The first stage employs a hydroprocessing catalyst which may contain hydrotreating catalyst, hydrocracking catalyst, or a combination of both. The subsequent stage is limited to hydrocracking. Conversion in subsequent stages may be improved by the addition of multiple reaction zones for hydrocracking, with flash separation zones between the stages. Middle distillate yield is thereby increased and the volume of the recycle stream is reduced. This invention reduces the need for equipment which would normally be required for a large recycle stream.
摘要翻译： 本发明包括具有至少两个阶段的加氢处理方法。 第一阶段采用加氢处理催化剂，其可以含有加氢处理催化剂，加氢裂化催化剂或两者的组合。 后续阶段仅限于加氢裂化。 后续阶段的转化可以通过加入多个反应区用于加氢裂化而改善，其中阶段之间具有闪蒸分离区。 因此中间馏分产率增加，并且再循环料流的体积减少。 本发明减少了对大循环流通常需要的设备的需求。
