For sake of probing the possibility of CVD at room temperature by way of laser plasma assisted technique, a new style of CVD device has been designed and manufactured, and was used on practical preparation of Si 3N 4 film from SiH 4 NH 3 N 2 system.
Based on the theories of mechanical vibration, electromagnetics, thermodynamics and combination of numeric simulation, a prototype machine is designed and manufactured. Simulations and experiments about are done to acquire the characteristics of the compressor and the influence of factors, such as friction force, gas force, equivalent parameters of coil, additional capacitance, static position of piston, stiffness of resonant spring etc.
Melt Spinning Processing Equipment (MSPE) was designed and manufactured in order to study the strengthening mechanisms of high strength Mg alloys produced by rapidly quenched solidification.
In this article,a highly nonlinear photonic crystal fiber with a pure silica core is designed and fabricated,of which the core diameter is 1.65μm,the air hole diameter 4.75μm,the space between the hole centers 5.35μm,the zero dispersion wavelength 1 120 nm and the dispersion at wavelength of 800 nm-88 ps/(nm.km).
To verify the formula,a pressure sensor of such type using a foilstrrain gauge of 6mm in diameter was developed with a measuring range from0 to 0.5MPa.
Therefore a PDC bit with new compound cutting structure is developed in the light of the characteristics of gravel formation and soft-hard interbedded formation.
A three-transistor active pixel and its testing circuit is designed and fabricated with chartered 0.35μm 2P4M N-well CMOS process to obtain the accur ate experimental value in the model.
Hardware of the drive and control system is based on TMS320LF2407A with powerful functions, transforms the power energy into PWM to drive and control the motor and realize the protective function by protective circuit.
A superconducting magnet system (SMS) for the multicharged ion source DECRIS-SC was designed and manufactured at the Joint Institute for Nuclear Research.
Three SMPU knitted fabrics series with different content of SMPU fibers: 100% SMPU, 50% SMPU and 50% cotton, 16% SMPU and 84% cotton are designed and manufactured in our lab.
Two types of under-water quartz transducers, namely, the mosaic type & the array type, were designed and manufactured, particularly paying attention to the points of cementing of crystals and supporting of vibrating bodies, with a view to reducing the equivalent resistance r of the transducers when they are unloaded. A transducer of the mosaic type with an area of 609 mm~2, unsupported, measured 60 k Ω for its r, while one of the array type with an area of 259 mm~2, 15 k Ω. Finally, discussions were made on...
By the end of 1958 the speciality of , high voltage technique and the speciality of electricalapparatus with the help of Soviet specialist A. I. Dolginov and. in cooperation with the SianInstitute of Apparatus and the Sian Insulator workn, have made the design of 330-kv magnetic-type lightning arrester and produced it. In this paper the test result of the interrupting abilityof gap is given and the method of calculating lightning arrester characteristics discussed.
In this paper the principle of simulating an axial and plane symmetrical magnetic field by a resistance network analogue is analysed. The method of current injection has also been discussed and the formula for the second order approximation was given. Based on the above principle, a resistance network analogue with associated apparatus was constructed. The central part of the network contains 10 X 14 units. It is extended by end strips to 28 and 32 units in z and r directions respectively. Experiments have ...
