Title: Method for estimating conversion efficiency of catalyst for purifying exhaust of internal combustion engine
Inventor: ISHII TOSHIO
IPC: F02D41/14
Filed: 1991-03-20
Abstract: PURPOSE:To judge deterioration of a catalyst well without breaking air/fuel ratio feedback by computing for estimation conversion efficiency of the catalyst on the basis of a cross-correlation function of the output signals of air/fuel ratio sensors located on the upstream and the downsteam sides of the catalyst for purifying the exhaust. CONSTITUTION:An engine control unit 11 controls fuel injection quantity with the fuel injection signal on the basis of a result of a computing process performed in response to the engine speed and a load of an internal combustion engine. At this stage, conversion efficiency of the catalyst 10 is computed for estimate on the basis of a cross-correlation function of the output signal of air/fuel ratio sensors 8, 9 located on the upstream and the downstream sides of catalystic converter rhodium for purifying the exhaust. Since judgement of deterioration of the catalyst 10 is thereby performed without generating dislocation from a set air/fuel ratio, judgement of deterioration of the catalyst is performed well without breaking the air/fuel ratio feedback.

In order to form the phoptoelectric screen 4, silver is vapordeposited on the inner wall of a face plate 3 from a silver particle 7 after a tube 1 is evacuated, then pure oxygen is introduced into the tube 1 before the oxygen gas is subjected to electric discharge in a high-frequency electric field thereby oxidizing the thin silver film. Next, a potassim case 9 is heated by feeding current to it so as to cause emission of potassium thereby adsorbing potassium on the above silver layer. Then cesium is caused to be emitted from a cesium case 10 thereby causing adsorption of cesium. After that, silver is again vapordeposited on the photoelectric screen. The thus manufacture photoelectic screen has a sensitivity to white light of 40-45muA/lm and an improved sensitivity to infrared rays of around 7-8muA/lm.

Filed: 1991-03-22
Abstract: PURPOSE:To generate the geographic model in a smooth solid shape by finding height data on mesh points on a two-dimensional plane which have a smaller pitch than dot array data on contour lines according to the dot array data. CONSTITUTION:After the mesh point and contour line data (Z=0) are generated, points on three contour lines closest to each mesh point are retrieved. Then it is decided whether or not the points on the contour lines can be retrieved for the mesh point and when not, the height data on the mesh is set to '0'. When the points are retrieved, it is decided whether the mesh point is inside the closest contour lines. When it is decided that the mesh point is not inside and when it is decided that the mesh point is inside, the height data on the mesh point is interpolated according to the distance, etc., between the mesh point and the intersection with the closest contour line which is obtained by connecting the mesh point and the 2nd close contour line.

Abstract: PURPOSE:To enable formation of the epitaxial layer having highly uniform film thickness over all of the plural substrates of arbitrary forms by forming a polycrystalline thin film deposition layer consisting of the same compound as crystal of the substrate on the suscepter for supporting substrates used for vapor growth of a compound semiconductor. CONSTITUTION:A polycrystalline thin film deposition layer 20 consisting of the same compound as crystal of the substrate 16 is formed on a suscepter 17 for supporting substrate crystal used for vapor growth of a compound semiconductor. For example, when placing the GaAs substrate 16 on the suscepter 17 to perform vapor growth of GaAs crystal, a GaAs polycrystalline thin film layer 20 deposited to about 50mum of thickness on the suscepter 17. Consequently, as growing speed of GaAs crystal on the GaAs polycrystalline thin film deposition layer 20 is the same as that on the GaAs substrate 16, there is practically no gap when the substrate is placed on the suscepter. Accordingly, the epitaxial growth layer having a fixed film-thickness distribution constantly irrespective of a shape or an area of the substrate to be placed can be obtained.
