Title: Method and apparatus for cleaning pipe
Inventor: MATSUDA SHINICHI
IPC: B21C43/00
Filed: 1980-12-26
Abstract: PURPOSE: To remove adhering matters at low cost in removing adhering matters on the inside of a large diameter pipe using high-speed air current containing abrasives by providing a metallic hollow spherical air-current accelerating member in the pipe and thereby accelerating the speed of air current by an air compressor of small capacity.  
     CONSTITUTION: In removing adhering matters 91 such as rust on the inside of a pipe 90 by high-speed air current containing abrasives such as sand, a hollow spherical air-current accelerating member 26 made of mild steel or light metal is held by a wire 28. Whirling air current is jetted from plural nozzles 25 through hoses 13, 20 and a cylinder 18 by driving a compressor 10. Abrasives 92 in a tank 40 are supplied to a discharge pipe 22 and sent into the pipe 90 by whirling air current, and adhering matters are removed by abrasives 92. Since there is an air-current accelerating member 26 in the pipe in this case, the sectional area of the inner face of the pipe 90 is small and the air current is accelerated. Thus, adhering matters are thoroughly removed even by a compressor 10 of relatively small capacity.

Filed: 1995-06-28
Abstract: PURPOSE: To provide a control method and a controller which have high robustness against the modeling error of an induction motor by a method wherein the renewal of a control setting value is discretely performed with a time interval which is longer than the time interval of the generation of a slip angle frequency command value. CONSTITUTION: The adaptive vector controller of an induction motor 1 has a rotation angular velocity detector 2, a current detector 3, a 2-phase/3-phase converter 4, a vector control system 51, a main control unit 5 composed of an adaptive identification system 52 and a power converter 6. If a slip angle frequency command value is generated continuously with a lapse of time and, further, a control setting value is renewed in accordance with a secondary resistance value which is identified by the adaptive identification system 52 discretely with a lapse of time, the control setting value of the secondary resistance is not renewed every time when the slip angle frequency command value is generated. With this constitution, the instability caused by the modeling error can be improved significantly.

Abstract: PURPOSE:To obtain a highly reliable semiconductor device by disposing semiconductor elements to a defective region which extends from interior of semiconductor substrate and reaches the surface thereof and the fault-free region isolated by insulating film and provided at the surface thereof and thereby perfectly eliminating influence of stray carrier. CONSTITUTION:A groove 23 is formed in the depth of about 3mum on a P type Si substrate 21, it is then annealed at a high temperature under the O2 ambient. Thereby, a fault-free layer 24 is formed in the thickness of 3mum or less. It is also annealed at a low temperature under the N2 ambient. Thereby the fault precipitation core is formed at the entire part 25, except for the layer 24. The fault-free layer 24 is isolated into several islands by the surface grinding. The P<+> layer 27 is formed by implanting boron ion through the Si3N4 mask 26, the surface is then oxidated and thereby a field oxide film 28 can be formed. At this time, a region 29 in which many minor defects are precipitated is generated at the region 25 and thereby the P<+> channel cut 27 is formed. Thereafter, when a dynamic RAM, for example, is formed by an oridinary method on the fault-free layer 24, a highly reliable device resulting in no erroneous operation can be obtained.
