Abstract: PURPOSE:To offer the manufacturing method of a semiconductor, in which a gate electrode does not come off and the degradation in withstanding voltage of said electrode can be prevented. CONSTITUTION:An SiO2 film 22 is formed on a p type silicon substrate 21 at a relatively high temperature. Thereafter, an MoSi film 23 is formed on said SiO2 film 22 by an evaporating method. Then a resist pattern 24 is formed on said MoSi film 23 by a photoetching method. It is removed by an ion etching method and a gate electrode 25 is formed. Then the resist pattern 24 is removed. With the gate electrode 25 as a mask, the SiO2 film 22 is etched by aqueous solution of NH4F and the like, and a gate insulating film 26 is formed. Then n<+> type source and drain regions 27 and 28 are formed by a self-aligning method. Thereafter a polycrystal silicon film 29 is formed by a CVD method at a relatively low temperature (550-650 deg.C). Then heat treatment of said polycrystal silicon film 29 is performed in an oxidizing atmosphere at a relatively high temperature (800-1,100 deg.C), so that the film 29 is transformed into a thermal oxide film 30. An interlayer insulating film 31 is further coated on said thermal oxide film 30 by a CVD method.

Title: Continuous casting method for hollow metallic pipe
Inventor: TAKEUCHI KATSUYUKI
IPC: B22D11/04
Filed: 1986-07-28
Abstract: PURPOSE:To prevent the holding of a core and to cast a pipe to a uniform wall thickness by disposing the core into a casting hole part of a casting mold, finely oscillating the core in the axial central direction of the hole part and drawing the cast pipe solidified and formed in the hole part. CONSTITUTION:Air A is passed through a communicating hole 19 from a supply hole 16 and is supplied into a hollow part 11 and a lower cylinder chamber 14b so that a piston part 10 and the core 5 are raised by the air pressure and the energizing force of a spring 15. The air pressure in the hollow part 11 and the lower cylinder chamber 14b is then released to the outside through a communicating hole 21 and a discharge hole 18, and the air B is supplied through a supply hole 17 and a communicating hole 20 into an upper cylinder chamber 14a. The piston part 10 and the core 5 are lowered by the pressure of the air B in the upper cylinder chamber 14a. The cast pipe 8 solidified and formed in the hole part 4 of the casting mold 1 is drawn by pinch rollers 9 while the core 5 is held finely oscillated vertically by repeating the above- mentioned action. The generation of a thickness deviation in the casting pipe 8 is prevented at this time, and the molten metal surface in contact with the core 5 is activated by the oscillation, by which the solidification is suppressed.

Abstract: PURPOSE: To enable efficient working of small diameter tubes etc. by placing plural forming coils so that a part of each coil is positioned on the same plane, and combining them to form a closed curve in connection with each other.  
     CONSTITUTION: By combining coils 3, 3 coiled in a plane, working of a tube 4 which is much smaller in diameter than minimum allowable radius of curvature ϒ of an electric wire can be made. However, this is low in power efficiency. When this is made to a three-dimensional channel-shaped coil 5, magnetic fields M', M" caused by the current that flows BCDE and FDHA are reverse in direction and cancels each other and only a magnetic field M caused by the current that flows through AB, EF is obtained. Accordingly, when this is connected and brought into close contact as coils 6, 6 or 7, 7, the two coils come into contact on a common plane, and on that plane, a part of the two coils form a closed curve which is regarded as a square. When current is let flow in the direction of the arrow, a strong magnetic field of steep rise-up is formed in the closed curve.
