IPC: F01N11/00
Filed: 1993-01-21
Abstract: PURPOSE:To detect the accurate deterioration of a catalyst during air-fuel ratio control by prohibiting any operation of a catalyst deterioration detecting means when a first or second air-fuel ratio compensation value goes beyond the specified range. CONSTITUTION:Each oxygen sensor (O2 sensor) as an air-fuel ratio sensor is installed at both up- and downstream sides of a catalytic converter provided in the exhaust system of an internal combustion engine. Before the value of an air-fuel ratio correction factor KO12 is settled to a lower limit value O2 LMIL, it comes to an equation of flag FKO2LMT=0, and any deterioration detection of a catalyzer is permitted. The value of a correction factor KO2 is settled to the lower limit value O2LMIL, it comes to an equation of flag FKO2LMT=1 at a step S111, therefore the catalytic deterioration detection is not permitted. In addition, at a step 113, even if the correction factor KO2 value is put back within the specified range from the lower limit value O2LMIL, the equation of the flag FKO2LMT=1 is continued till the specified time tOPEN elapses, and the deterioration detection is permitted after air-fuel ratio control is stabilized.

Abstract: PROBLEM TO BE SOLVED: To obtain aluminum polysulfate capable of improving flocculating performances of aluminum polychloride(PAC) by adding aluminum polysulfate to PAC by using hydrargillite-based crystalline aluminum hydroxide as aluminum hydroxide and reacting the aluminum hydroxide with sulfuric acid at a specific temperature. SOLUTION: Aluminum hydroxide is reacted with sulfuric acid at 100-140 deg.C. The reaction pressure is 0.05-1.0 MPa. A reactor used is preferably an acid- resistant and pressure-resistant one. The reaction is preferably carried out in a closed state. The reaction time is 1-8 hours. The ratio of sulfuric acid to aluminum hydroxide is 0-10% excessive aluminum hydroxide based on the theoretical amount of aluminum hydroxide necessary for a desired basicity. The basicity of obtained aluminum polysulfate is 10-50%. Sodium hydroxide, and the like, are used as an alkali agent for adjusting basicity. The amount of aluminum polysulfate added to PAC is an amount to form 1.5-3.5% sulfate radial in the PAC.

Filed: 1988-02-08
Abstract: PURPOSE:To prevent the overcooling condition to prevent frosting, by a method wherein vent holes are provided at the outer periphery of a cooling plate while airflow direction deflecting plates are provided on the upper surface of a partitioning plate. CONSTITUTION:Most of cold air, passing through a first ventilating passage 15, flows along the bottom surface of a cooling plate 13 and cools the cooling plate 13. One part of the cold air passes through vent holes 26, flows out of a front opening through the bottom surface of a first ice making pan 17 or the upper surface of the same pan 17 and returns to a return passage 22. The amount of cold air, which flows on the first ice making pan 17, is corrected by airflow direction deflecting plates 28. Accordingly, either one of the right or left side of the first ice making pan 17 may be prevented from falling into overcooled condition. On the other hand, the vapor of water, which is evaporated during producing transparent ice, can not be adhered to a heating plate 12, since the temperature thereof is high, and flows to the bottom surface of the first ice making pan 17, however, cold air from the venting holes 26 flows slightly along the bottom surface of the same, therefore, the vapor of water flows to the opening of an ice making chamber 25 whereby frosting will never be generated on the cooling plate 13 or the inside of the ice making chamber 25.

Abstract: PROBLEM TO BE SOLVED: To provide a position noticing equipment and the position noticing system in which the position of the person possessing the equipment is retrieved. SOLUTION: Upon the receipt of a base station code sent from a radio base station, a portable terminal equipment 10 stores the received base station code and discriminates whether or not a newest base station code is coincident with the base station code stored in a registration base station code memory.

Title: Method and equipment for inspecting semiconductor device

IPC: G06T7/00
Filed: 1995-02-16
Abstract: PURPOSE: To obtain method and equipment for inspecting a semiconductor device in which deformation of lead or the like of the semiconductor device is detected by processing a light- and-shade image thereof picked up from the upper part. CONSTITUTION: A semiconductor device 2 is illuminated by a light source 5 disposed obliquely above the lead or the like formed on the semiconductor device 2, and picked-up by a camera 4 disposed above the device 2. A light-and-shade image thus obtained is then subjected to differentiation in the direction of illumination by means of an image processor 6 and the extent of deformation is determined based on the variation in the light-and-shade level obtained through differentiation. The light-and-shade image has light-and-shade level approximately proportional to the gradient from the horizontal direction and the light-and-shade level obtained through differentiation is approximately proportional to the curvature of the plane to be inspected.  Consequently, deformation of the lead or the like of semiconductor device can be detected by comparing the curvature with a reference value for deciding pass/fail of deformation test. Since deformation in the horizontal direction can be detected on the light-and-shade image, deformation of the lead or the like can be detected simultaneously in horizontal and vertical directions from one image of the semiconductor device picked up from the upper part.

Abstract: PURPOSE:To prevent the bound at the time of fully opening a blade, to take a photograph with a desired exposure and to prevent the distortion of an image on a peripheral part by providing a means butting against the surface of a part of the blade and bending it, at the time of fully opening the blade. CONSTITUTION:A shutter blade riding projection 36h is formed in the locus of the turn of a shutter blade 14 arranged on a side nearer to the front surface, and in the vicinity of the releasing position of the shutter blade 14. The front surface of the shutter blade riding projection 36h, that is, the projected surface is a slope gradually lifted up forward as it approaches the releasing position of the shutter blade 14 and when the shutter blade 14 approaches the releasing position, the shutter blade 14 is ridden on the slope of the shutter blade riding projection 36h and fictional resistance is increased. When the shutter blade 14 ridden on the slope of the shutter blade riding projection 36h reaches the releasing position, the bound from the releasing position is suppressed and the shutter blade 14 never covers a part of the peripheral region of a focus lens group 10, because kinetic energy is changed into the frictional resistance.
