An electronic apparatus includes a cover, a latch fixable to the cover and a base pivotally connectable with the cover. The latch includes a hook having a shank portion and a hook portion extending from the shank portion, and the shank portion defines a slanted surface thereon. The base includes a retaining portion engagable with the hook portion of the latch for fixing the cover to the base, and a stopper portion along which the slanted surface of the shank portion is slid thereby causing the cover to lift away from the base.

A fixing apparatus for fixing a hard disk drive includes a bracket receiving the hard disk drive with a locating pin extending from each of opposite sidewalls, and a rotating member. The bracket includes two opposite supporting walls and an end wall. Each supporting wall defines a latching slot. The locating pins are slidably inserted into the corresponding latching slots. The rotating member includes a fixing pole slidably abutting against the hard disk drive toward the end wall, two rotating poles respectively extending from two opposite ends of the fixing pole and rotatably connected to the corresponding supporting walls, and a latching pole extending from a distal end of one of the rotating poles to be detachably latched to one of the supporting walls.

A fixing apparatus for holding a data storage device is provided. The fixing apparatus includes a drive bracket, and an insertion rack. The drive bracket includes two opposite side panels. Each of the side panels forms at least one guiding portion and defines a slot therein. The insertion rack is configured for inserting the data storage device into the drive bracket. The insertion rack forms two hooks. The insertion rack is capable of sliding into the drive bracket along the guiding portions. The hooks ride along an exterior of the drive bracket until they are inserted into the corresponding slots of the drive bracket.

A method for secondarily synthesizing calcium sulphoaluminate mineral in Portland cement clinker is provided. The method includes adding gypsum into raw Portland cement, calcination, then heating twice to re-form calcium sulphoaluminate mineral that has decomposed at high temperature in the clinker. This method can increase the content of calcium sulphoaluminate mineral in the clinker. As a result, the advantages of the calcium sulphoaluminate mineral in the clinker may be obtained, such as improvement of the early stage performance and long-term performance of the cement clinker and increase in the quantity of mixture in the cement.
摘要:
The present invention relates to a process of controlling crystal form of Alite in Portland cement clinker, wherein the said Portland cement clinker is thermally treated in order to change the crystal form of Alite in Portland cement clinker, so as to improve performance of resulting Portland cement clinker. The said process of present invention is easy and feasible.
