Title: Manufacture of ultra fine grain powdered quick lime of high purity
Inventor: INOUE HIROTSUGU
IPC: C01F11/02
Filed: 1979-06-11
Abstract: PURPOSE: To obtain ultra fine grain powdered quick lime of high purity in a high yield by converting quick lime into milk of slaked lime and removing coarse grains by classification or other method after which the resulting slaked lime grains are surface covered with Ca salt of a fatty acid or the like, dehydrated, dried, and calcined.  
     CONSTITUTION: Quick lime is converted into milk of slaked lime by wet slaking, and coarse grains are removed by classification or screening. The resulting slaked lime grains are surface covered with Ca salt of a fatty acid such as capric acid or lauric acid and/or Ca salt of resin acid or calcium carbonate, dehydrated by a usual method, dried, and calcined at the decomposition temp. or above, e.g., about 900W 1,250°C. Thus, aggregation of dried slaked lime grains is prevented, and ultra fine grain powdered quick lime of high purity is obtd. This quick lime has enough fine grain size for use as a water absorbing agent for rubber.

Title: Obstacle detector
IPC: B60W30/00
Filed: 1992-03-30
Abstract: PURPOSE:To detect the motion of an obstacle so as to take a proper avoiding action corresponding to the degree of danger by detecting the motion pattern of the obstacle and performing the avoiding operation based on its classification result. CONSTITUTION:Right and left laser radar head units 2 measure the motion direction and the speed of the obstacle. A signal processing unit 3 detects the motion direction, the position, and the speed of the obstacle based on the measurement result to obtain the motion pattern. This unit classifies this motion pattern as crossing in the, or entering a dangerous area from the outside, or going-out outsides this area. At this time, the unit 3 classifies the area, where the obstacle exists, as a 'dangerous area where collision is inevitable', an 'adjacent area where collision is possible', or an 'area where precaution is necessary'. Thus, the signal processing unit 3 deduces the position, the distance, and the degree of danger of the obstacle after a prescribed time to avoid the obstacle.

Title: Method for estimating coke strength
Inventor: ARIMA TAKASHI
IPC: C10B57/04
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To estimate coke strength with good accuracy by estimating the amounts of powdery cokes produced by surface fracture and bulk fracture from the properties of the respective coals to be blended and estimating the strength of the coke to be produced from their sum. SOLUTION: The properties (e.g. expansion ratios and specific volumes) of the respective coals to be blended are measured to estimate the amount of the powdery coke produced as a result of surface fracture and that of the powdery coke produced as a result of bulk fracture. From the sum of these amounts, the strength of the coke to be produced by carbonization is estimated.  An example of the method comprises estimating the amount of the powdery coke produced as a result of the surface fracture of coke from the relationship between the value determined by finding the weight-fraction-weighted average of the expansion ratios or specific volumes of the coals to be blended and the amount of the 6mm or smaller powdery coke after a coke strength test and estimating the amount of the powdery coke produced as a result of the bulk fracture from the re-solidification temperature, etc., of the coal blend.

Title: Production of magnetic disk
Inventor: SATO MOTOHARU
IPC: G11B5/852
Filed: 1990-03-23
Abstract: PURPOSE:To improve the coercive force and squareness ratio of a recording medium by forming a Co-base alloy magnetic layer on a carbon substrate and then subjecting this layer to heat treatment at specified temp. in a magnetic field orienting in the circumferential direction of the disk. CONSTITUTION:After the magnetic layer 3 comprising a Co-base alloy such as Co-Ni-Cr, Co-Ni, Co-Ni-Pt, Co-Cr, and Co-Cr-Ta is formed on the carbon substrate 1, this layer is subjected to heat treatment at 250 - 1450 deg.C in a magnetic field orienting to the circumferential direction of the disk. By this method, boundaries of grains in the Co-base alloy magnetic layer 3 are selectively oxidized, and moreover, segregation of Cr on the grain boundaries can be promoted when the Co-base alloy magnetic layer 3 contains Cr. This makes each grain of the Co-base alloy magnetic layer 3 behave as a single magnetic domain, which increases the coercive force and squareness ratio.
