Title: Purifying method for magnesium hydroxide
Inventor: TAKAMIYA YOUICHI
IPC: C01F5/14
Filed: 1980-08-19
Abstract: PURPOSE: To considerably reduce the amount of industrial water for washing, to almost prevent silica from mixing, and to reduce the size of an apparatus by washing a cake layer obtd. by press-dehydrating the minus mesh part of a conc. Mg (OH) 2  slurry.  
     CONSTITUTION: An Mg(OH) 2  slurry obtd. by the reaction of decarboxylated seawater with slaked lime or milk of lightly burned dolomite is concd. to ≥100g/l solid concn. with a thickener or the like, fed to a vibrating screen apparatus 2 from a pipe 1, and screened with a screen 3 having ≤44μm mesh. The preferred screen 3 is a vibrating screen provided with a controller 6 and discharging the plus mesh by closing a valve A and opening a valve B from the viewpoint of capacity and efficiency. As the mesh of the screen is made smaller, the purity of a product is increased, so the mesh is decided according to the purity. The slurry freed of solid impurities is then dehydrated with a press dehydrator under ≥0.5kg/cm 2  pressure to remove impurities such as Ca ion. The resulting cake is washed by injecting water. By blowing compressed air into the washed cake, the water content of the cake can be lowered.

Abstract: PURPOSE:To obtain apparatus which can detect a position in a relatively high speed and with high precision, by roughly detecting the position by means of the pattern matching wit binary signals of a bright field detection image, and finely detecting the position by means of the pattern matching with multivalue signals of a dark field detection image. CONSTITUTION:An automatic alignment interface 31 is provided with a generator of correlative functions which, on the basis of a picture signal from a TV camera, compares a small part of the image pattern in a predetermined region on a wafer 4 with the pattern of a template and generates a correlative function representing a pattern matching degree between patterns. An illumination interface 32 controls the ON/OFF operations of a lamp 33 for illuminating the bright field and a lamp 34 for illuminating the dark field. For rough positional detection, the pattern matching is performed with a bright field binary detection image having a wide bottom which allows easy detection of a peak of the pattern matching degree and rapid processing. For fine positional detection, the pattern matching is performed with a dark field multivalue detection image having large variations which allows highly accurate positional detection.
