摘要:
The present invention relates to a map generating and updating method for mobile robot position recognition, and more specifically relates to a map generating and updating method for mobile robot position recognition, whereby position recognition error can be minimised by registering landmarks extracted during map generation and landmarks extracted on the basis of the probable error in inferred landmarks, calculating the accuracy of landmarks pre-registered during map generation, and adjusting the level of landmarks of low accuracy or removing landmarks which have been registered erroneously.

A method of manufacturing an Fe/Ni-containing material having a low content of sulfur from an Fe/Ni/SO4-containing liquid waste, a ferronickel mass using the Fe/Ni-containing material, and a method of manufacturing the ferronickel mass. The method includes: removing SO4 from an Fe/Ni/SO4-containing liquid waste by adding an SO4 neutralizing agent to the liquid waste so that pH of the liquid waste can be maintained to a pH level of 0.5 to 2.5; precipitating Fe and Ni in the form of hydroxide [(Ni,Fe)(OH)] by adding NaOH to the SO4-free solution; washing the precipitate with water; and manufacturing an Ni/Fe-containing material by filtering and drying the washed Ni/Fe-containing sludge. The method may be useful to suitably apply to the field of recycling of waste acids since an Fe/Ni-containing pellet and a high purity plaster are recovered as the stainless steel material from the waste water at the same time.

There are provided a method of manufacturing an Fe/Ni-containing material having a low content of sulfur (S) from an Fe/Ni/SO4-containing liquid waste, a ferronickel mass using the Fe/Ni-containing material, and a method of manufacturing the ferronickel mass. The method of manufacturing an Fe/Ni-containing material from an Fe/Ni-containing liquid waste includes: removing SO4 from an Fe/Ni/SO4-containing liquid waste by adding an SO4 neutralizing agent to the liquid waste so that pH of the liquid waste can be maintained to a pH level of 0.5 to 2.5; precipitating Fe and Ni in the form of hydroxide [(Ni,Fe)(OH)] by adding NaOH to the SO4-free solution; washing the precipitate with water; and manufacturing an Ni/Fe-containing material by filtering and drying the washed Ni/Fe-containing sludge. The method of manufacturing an Fe/Ni-containing material may be useful to suitably apply to the field of recycling of waste acids since an Fe/Ni-containing pellet and a high purity plaster are recovered as the stainless steel material from the waste water at the same time.

The present invention relates to a parallel-ring integrated antenna. The integrated antenna in accordance with the present invention includes a parallel ring including a plurality of rings and a central conductor, and a high dielectric body coupled to the parallel ring. Return loss can be changed depending on a thickness of the ring, a first diameter, i.e., a diameter of the ring, a distance between the rings or a second diameter, i.e., a diameter of a central conductor. Further, the high dielectric body has a groove formed therein to correspond to an external shape of the parallel ring. The parallel ring is coupled to the high dielectric body through the groove. Thus, the integrated antenna of the present invention can obtain a maximum gain and active performance while maintaining the size of an existing chip antenna and can have its size and structure changed easily and conveniently by combining the high dielectric body with the parallel ring.
摘要:
A method for manufacturing a semiconductor device is capable of increasing the size of a landing plug without loss of an insulating film separating the landing plug, and may be advantageously used for reducing contact resistance by enlarging a landing plug contact hole without causing the loss of the insulating film due to a cleaning solution during a wet cleaning process. The semiconductor device manufacturing method includes the steps of: forming a gate over a semiconductor substrate and forming an interlayer insulating film filling spaces between the gates; selectively etching the interlayer insulating film to form a landing plug contact hole; forming a primary landing plug filling the landing plug contact hole preferably by a selective epitaxial growth method; forming, over the gate, a buffer dielectric film of an over-hang structure; and forming, over the primary landing plug, a secondary landing plug as a conductive film.
