Title: Image data encoding device
Inventor: YAGISHITA TAKAHIRO
IPC: H04N19/176
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To provide an image data encoding device with which high compressibility can be provided in the mixed picture of character/image. SOLUTION: When multilevel two-dimensional(2D) image data are inputted, an image data dividing part 1 divides these image data into blocks. A frequency converting part 2 finds the conversion coefficients of respective bands while dividing the frequency of image in each divided block into four bands of horizontal high area, vertical high area, diagonal high area and low area and converts each pixel in that block to the cluster of found conversion coefficients. A discriminating part 3 discriminates the level of pixel value in the block divided by the image data dividing part 1 and discriminates whether that block shows a character area or an image area. Corresponding to the discriminated result, a quantizing part 4 quantizes the conversion coefficient outputted from the frequency converting part 2, and an encoding part 5 performs data compression through entropy encoding to that quantized coefficient. A memory 6 stores the compressed data.

Filed: 1992-05-11
Abstract: PURPOSE:To simply assay an ultramicro-amount ingredient with high sensitivity by supplying a predetermined volume of slurrylike particular substance by volumetric dispensing when a particulate substance is supplied to a reaction system. CONSTITUTION:When a predetermined volume of gel is added, an open end 8 of a measuring tube 5 is introduced into a vessel 9 filled with slurrylike gel 7, the gel 7 is sucked by a syringe 1, and fills the tube 5. According to this method, the gel 7 of 0.05 or less of dry weight can be volumetrically dispensed by 0.8% of a relative standard deviation. Then, the gel 7 in the tube 5 is extruded by the syringe 1, and added to sulfuric acid solution, ascorbic acid solution to be analyzed. Thus, since less particulate substance can be accurately volumetrically dispensed and a quantity of the substance to be used for analysis can be reduced, a concentration magnification of coloring ingredient is raised, and sensitivity is improved. Since it is not necessary to previously weigh the gel 7, an operation is simple.

Title: Casting roll and method of overhauling said roll
Inventor: BUIRUHERUMU FURIIDORITSUHI RAU
IPC: B22D11/06
Filed: 1987-05-13
Abstract: Rods are placed into axially arranged grooves of the roll core. These rods protrude radially from the roll surface and the roll shell is shrink-fitted onto the rods. Due to the creeping movement of the roll shell which is a result of periodical heating and cooling thereof, the inside surface of the shell and the interfacing outside surface of each rod are subject to wear. Whenever this wear has proceeded beyond a tolerable limit the rods are replaced, whereafter a new shell with a normal inside diameter is again shrink-fitted onto the rods. Thereby the rod's and the shell's dimensions must never be changed. The roll core is not subject to wear. Stock-keeping and fabrication are particularly simplified due to the fact that the dimensions of the replacement parts never change.
