20160097030 | Bacteria Culture Medium and Applications Thereof - The present invention has publicized a bacteria culture medium. In common bacteria culture medium, one kind or several kinds of β-lactam antibiotics and/or the salts thereof were premixed. The β-lactam antibiotics and/or the salts thereof premixed in the bacteria culture medium is slightly soluble in water at 25° C. and the solubility is less than 10 mg/ml. The concentrations of the β-lactam antibiotics premixed in the culture medium are greater than the solubility of the used β-lactam antibiotics at 25° C., but are less than 100 mg/ml. The bacteria culture medium can be used to selectively culture bacteria with β-lactam antibiotic resistance and can be stored for a long time. | 04-07-2016 |

20150252450 | Process of Preparing Aluminum Alloy - The present invention provides a process of preparing an aluminum alloy, comprising the following steps: a first step of adding a ZL101 aluminum ingot and covering the melt after complete melting said alloy; a second step of adding one of modifiers Te and Sb and then performing heat preservation; and a third step of adding one or more of rare earth elements La, Ce, Y and Hf and then performing heat preservation. The ZL101 alloy melt after the treatment can be casted into an ingot or a part after refining, and a high-toughness ZL101 Al—Si alloy can be obtained after cooling. By adopting the combined effect of the rare earth elements and the long-acting modifiers, the present invention realizes controllable morphology of α-Al and eutectic Si, and inhibits the formation of α-Al dendrites and the generation of the long strip shape eutectic Si in a solidification process, thus the high-toughness ZL101 Al—Si alloy is prepared. | 09-10-2015 |

20130335916 | PORTABLE TERMINAL - A portable terminal has a main machine body and a cell, one of the main machine body and the cell is arranged a pushing button moving axially, and a compression spring is arranged between the pushing button and the one of the main machine body and the cell, the other has a clamp slot of which a notch extends axially, and the main machine body and the cell is clamped at the axial direction by the pushing button and the clamp slot. The portable terminal also comprises a lock cover connected with the pushing button, and a torsional spring is arranged between the lock cover and the pushing button, so that the lock cover and the pushing button can rotate along the spring-body axis of the torsional spring; when the torsional spring is reset, vertical distance between one end of the lock cover and the cell or the body arranged the compression spring is smaller than the distance that the pushing button inserts into the clamp slot. The lock cover in the present invention can achieve double-clamping at the axial direction for the cell and the main machine body. The pushing button can tightly lock the cell and the main machine body even if the portable terminal is dropped down or impacted. The cell can be taken from the main machine body only by adding certain torque to the torsional spring while in the assembling or disassembling operation, operation is simple and convenient. | 12-19-2013 |

20090064772 | Atomic force gradient microscope and method of using this microscope - A scanning probe microscope in which the probe is oscillated at a frequency lower than its resonant frequency, a force sensor that is sensitive to the bending of the cantilever and minimally sensitive to the oscillation is used to measure tip-sample interaction force. The sensor signal is then converted to a force gradient signal by electronics. The gradient signal is kept constant by a feedback mechanism as the tip is scanned across the surface of a sample, and force and topographical information are mapped. | 03-12-2009 |
