摘要:
A method of selective growth without catalyst on a semi-conducting structure. According to the method, which is applicable in electronics in particular: a semi-conducting structure is formed from first gaseous or molecular flows; at a same time or subsequently, at least one second gaseous or molecular flow is added thereto, to selectively in situ grow a dielectric layer on the structure; and then another semi-conducting structure is grown thereon from third gaseous or molecular flows.

A wholly air-controlled impact mechanism invented for creating a more compact and powerful pneumatic wrench comprises a flying hammer, a pressure impulse generator and a pressure container containing the hammer and the generator. The main part of the flying hammer is a flywheel with 2 cavities and a number of air passages. A pilot valve and an impact pin are fitted in the cavities. The impact pin rests in its cavity during energy-accumulation phase and stretches out rapidly from the flywheel to finish an impact during impact phase. The generator transmits pressure impulse periodically, affecting the differential pressure acting on the pilot valve. The higher the differential pressure, the greater the impact torque developed. The unique design of the air passages of present invention results in a very reliable, powerful and durable energy-accumulating pneumatic wrench. Its production cost is much lower due to simplicity of its configuration.
