The invention discloses a guide system for hip replacement and a using method thereof. The guide system comprises a handle, a guide connecting rod, an acetabular cup connector and a sleeve. The lower end of the handle is connected with the acetabular cup connector. One end of the guide connecting rod is connected with the side close to the upper end of the handle, a sleeve hole is formed in the other end of the guide connecting rod, and the sleeve is nested into the sleeve hole. The acetabular cup connector comprises a mounting shaft which can be connected with an acetabular cup in a rotating mode, and the center axis of the sleeve is roughly overlapped with the axis of the mounting shaft. According to the guide system for hip replacement and the using method thereof, the guide system is easy to assemble and disassemble and convenient, quick and accurate to use, the completion time of minimally invasive surgery is greatly shortened, any muscle and any joint capsule do not need to be cut off in the operation process, an acetabular component can be accurately positioned, inserted and pressed in a matched mode, and dislocation can be avoided.

A method of fabricating a MOS transistor having shallow source / drain junction regions is provided. A diffusion source layer is formed on a semiconductor substrate on which gate patterns are formed. Same type or different type of impurities are implanted into the diffusion source layer several times in different directions. As a result, dislocation does not occur and the impurity concentration of the diffusion source layer can be nonuniformly controlled so that damage to the crystal structure of the semiconductor substrate does not occur. Also, the impurities nonuniformly contained in the diffusion source layer are diffused into the semiconductor substrate by a solid phase diffusion method to form shallow source / drain junction regions having LDD regions and highly doped source / drain regions by a self-alignment method.

The invention discloses a cable inner core wire oil passing device, which belongs to the technical field of cable spray oil passing, and comprises a casing, a rear casing is fixedly installed on one side of the casing, and two sides of the casing are The outer walls are provided with inner core grooves, and a driving motor is fixedly installed on one side of the outer wall of the rear shell. There is a transmission assembly on the outside, which is used for the stable wire of the cable, and the transmission assembly is located in the shell cavity of the rear shell; in the present invention, the transmission assembly and the wire mechanism are arranged inside, and the oil sprinkling assembly is arranged inside, Through the linkage design, the conduction of the cable, the preliminary oiling and the stirring of the oil can all be realized through the same driving source, which reduces the energy consumption. At the same time, the real-time stirred oil is widely sprayed to ensure the preliminary oiling effect.

The invention comprises the grower adopting a Mo crucible pulling method heated by resistance and the crystal growing method comprising two procedures and four phases. The laser crystal of YAS series provided by the invention has large size of 35 to 50mm, high concentration (reaching 2.0at percent), no core, no dislocation and no scattering. In addition, the growing technology is stable; growing cycle is short; cost is low; and the yield of the crystal is high with above 85 percent.

The invention relates to the technical field of molds, in particular to a mold with an exhaust insert convenient to disassemble and assemble. The mold comprises a mold core, the exhaust insert, an insert base and a first mold plate. The exhaust insert is arranged on the insert base, the insert base is arranged on the mold core, and the mold core is arranged on the first mold plate. The mold further comprises an ejection rod, an ejection rod base and a cam. The first mold plate is provided with a guide hole for the ejection rod to move in the axial direction. One end of the ejection rod is connected with the insert base, and the other end of the ejection rod is connected with the ejection rod base. The cam is connected to the insert base in an abutting mode and presses the ejection rod to move in the axial direction under the drive effect of external force. Compared with the prior art, there is no need to disassemble the mold core and the mold plate when the exhaust insert needs to be cleaned, the exhaust insert can be disassembled through the compact matching structure of the cam and the ejection rod, the reliability is high, energy consumption is small, and the work is stable.
