Title: Method and apparatus for analyzing minute foreign matter, and manufacture of semiconductor element or liquid crystal display element using the method and apparatus
Inventor: FUJINO NAOHIKO
IPC: H01L21/66
Filed: 1995-02-14
Abstract: PURPOSE: To make it possible to observe, analyze and evaluate minute foreign matter by linking the coordinates of the respective apparatuses of a particle inspecting apparatus and an analyzer by using the same coordinate system based on the shape of a sample. CONSTITUTION: A sample wafer is mounted on the stage of a particle inspecting apparatus, and laser light is cast. Two points of the read-out orientation flat parts are connected, and an inclination an is computed. By the same way, the central coordinates of three points, which are read at an arc part, are computed. The coordinate system, wherein the inclination an is 0 and the central coordinates become the original point, is set. The correlation functions of the coordinate system and the coordinates of the apparatuses are obtained. The apparatus coorinates are converted into the coordinates of the coordinate system based on the shape of the sample. Then, the wafer is mounted on the stage of the analyzer, and the same operation is performed, but the light is not cast, and the position of the wafer of the wafer edge is recognized with a microscope.  The position value is read and added to the apparatus coordinates, and the coordinate system is set on the coordinates. Then, the correlation function with the coordinate system is obtained. Both apparatus coordinates are correlated with the coordinate system as a parameter. Therefore, the position of the minute foreign matter detected in the inspecting apparatus can be specified in the visual field of the analyzer having the high magnification.

Inventor: KISHIDA MITSUHIRO
IPC: H02B13/02
Filed: 1979-03-05
Abstract: PURPOSE:To maintain the acceleration response at the bushing attached section less than the degree of acceleration of earthquake by coupling a supporting section, of at least 3-direction and provided at a pedestal with equal angle against the pedestal, to the attaching flange of bushing by means of a damper. CONSTITUTION:A pedestal 5 having the supporting section 5a, which is consisted of a U-typed cut-in opposing to supporting flange section 4a, is installed on the ground, and a main transformer 1 and a tank-type switch 2 are fixed. And, a supporting metal fitting 6 is fixed to the supporting section 5a opposing to the flange section, and the metal fitting 6 and the flange section are coupled by dampers 7. Hereby, when vibration acceleration is going to be amplified at the section where the switch 2 and the bushing installed pedestal 2a are installed at the time of an earthquake, the response acceleration at the bushing installed pedestal 2a will not particularly be amplified due to the vibration energy absorbing efficiency of the dampers 7. The acceleration response is, therefore, maintained at a point less than the acceleration limit at which the long bushing 4 installed at the flange 4a can endure.

Abstract: PURPOSE:To suppress the fluctuation of the controlled variable for disturbance,  by using an extension model, to which the integral characteristics of the deviation between the controlled variable and a set value of a plant is added, to control a controlled system most suitably. CONSTITUTION:A most suitable controlling system 100 incorporating a model controls a system where a feed forward controlling system 200, a subloop controller 300, and a thermal power plant 400 are combined. A load demand change rate LDR from the system 200 is regarded as the disturbance, and controlled variable deviations such as a power generation output deviation MWE and a main stream pressure deviation PMSE are used as the controlled variable, and the extension model where the integral characteristics of the controlled variable deviation of the plant 400 is added to a model having the characteristics, where the generation process of the disturbance and the controlled system are combined, is generated. This extension model is used to control the controlled system of the system most suitably. Thus, the controlled variable is made coincident with the set value without offset in the steady state, and interferences among plural controlled variables are suppressed to suppress the fluctuation of the controlled variable for the disturbance.
