IPC: H02P29/00
Filed: 1991-04-01
Abstract: PURPOSE:To shorten the regulating time and to achieve suppressing effect on torsional vibration of a shaft by simplifying the constitution of observer. CONSTITUTION:A difference detecting section 11 produces a difference between a speed command and the speed of a motor. The difference is then amplified through a first control amplifier 12 and fed to plus input terminal of first subtracting section 13 having minus input terminal being fed with torque error output. Subtracted value from the first subtracting section 13 is amplified through a second control amplifier 14 in order to compensate for a torque command through feedback. Output from the second control amplifier 14 and an estimated torque are added at an adding section 15 in order to perform feedforward compensation of the torque command with the estimated torque. An estimated torque observer section 17 outputs an estimated torque which is then employed, together with an output from a high speed torque estimating section 22, in the operation of estimated torque error at a second subtracting section 25.

Filed: 1984-04-06
Abstract: PURPOSE:To deepen the penetration depth and to prevent the foam generation by controlling the generated plasma of a large output laser beam, by irradiating a laser beam through a nozzle on the body to be welded inside a vacuum welding chamber and by preventing the air flowed in the nozzle. CONSTITUTION:A large output laser beam 15 is irradiated with its convergence through small diameter opening nozzles 3, 4 on the body 9 to be welded of the above of the carriage 7 which is moved by the push rod 8 inside the vacuum welding chamber 1 which is exhausted from pipes 13, 14. In this case, the air flowed in from the opening nozzle 3 is prevented by the blowing air 12 from the ejecters 5, 6 facing for the outer part of the nozzle 3. The large output laser beam 15 in vacuum that the pressure inside the chamber 1 is made about 70Torr like this constrains the plasma generation, deepens the penetration depth and prevents the porosity generation. The large output irradiation is made possible because of no optical system being used for the laser beam 15 focusing. The effect is further increased by removing the generated plasma by blowing an inert gas from the side part nozzle 9 to the irradiating part.

Title: Manufacture of semiconductor device
Inventor: MIYAGAKI SHINJI
IPC: H01L29/40
Filed: 1991-04-01
Abstract: PURPOSE:To enhance permeability by forming a transparent conducting film on a substrate based on a sputtering process and then removing a contaminated layer and a degraded layer formed on the surface of said transparent conducting film accompanying a drop in the temperature of the transparent conducting film. CONSTITUTION:An about 1000 to 2000Angstrom  thick transparent conducting film 5 is formed on a transparent substrate 3, such as glass or quartz. A contaminated layer and a degraded layer are formed on a portion below about 100Angstrom  from the uppermost surface of the transparent conducting film 5 induced by the degradation of the surface of the transparent conducting film 5 during the process being cooled from the temperature on the surface of the transparent conducting film 5 during the manufacturing process or the sputtering process. Therefore, after the transparent conducting film 5 is formed and cooled, the contaminated layer and the degraded layer 5' whose thickness is about 100Angstrom  are removed from the uppermost surface of the transparent conducting layer by using a wet etching process based on an about 12% oxalic acid aqueous solution bath at a temperature of about 40 deg.C so as to obtain a transparent conducting film 5a. I is, therefore, possible to eliminate surface contamination after the formation of he film or surface degradation and hence obtain high permeability.
