Title: Combustion of pulverized coal
Inventor: AZUHATA SHIGERU
IPC: F23C1/00
Filed: 1988-12-31
Abstract: PURPOSE:To improve the burning rate of pulverized coal by its characteristic that it contains more than a certain amount of particles which have particles whose particle diameters are below a certain value. CONSTITUTION:In the burning of pulverized coal in which the pulverized coal is mixed with air and the mixture is jetted out from a burner and burned, the pulverized coal contains more than 20wt.% of the particle, diameter of which is below about 20mum, or more than 30wt.% of the particle, diameter of which is below about 10mum. And the maximum particle diameter in the pulverized coal is below 150mum. In order to form a stable flame a sufficient amount of pulverized coal which have minute particles and accompany the air flow in the vicinity of the burner outlet and are easy to be mixed with the air are added in the pulverized coal to improve the combustibility. Since the pulverized coal with a small particle diameter is light in weight and easy to accompany the air flow and has a large specific surface area, heat is easy to penetrate to the core of the particle and it is easy to be ignited. It is, however, a disadvantage as far as the cost of pulverization is concerned to work on all the particles. Accordingly the combustibility is improved by the pulverized coal which contains the coal of particle diameters in the range above mentioned in said rate.

Title: Device and method for processing recording/reproducing
Inventor: OGAWA YASUYUKI
IPC: G11B20/10
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To execute/restart smoothly copy processing with simple operation by adding the identification data which are not overlapped with the identification data of another information to the information to be copied. SOLUTION: The total of sizes of main image data files, etc., of a selected image is calculated. When a free capacity of a copy destination recording the data of the calculated sizes is recognized, a recording/reproducing processing part 100 confirms whether or not a data file having the only one file number is formed newly. When the copyable state is confirmed, the copy processing of the main image data file, etc. is performed. In the copy processing, the attribute information of the data file of a copy origin is reflected as it is on the attribute information in the data file of the copy destination. When the copy processing success is confirmed, after the file number of the newly generated data file is stored in a nonvolatile memory 56, the copy processing is ended.

IPC: G01D21/00
Filed: 1994-12-15
Abstract: PURPOSE: To improve the detection precision even for the distribution in which the frequency distributions of measured values of respective measuring instruments and measured value variation quantities are not in normal distribution by detecting abnormality of a measured value on the basis of a reference range determined on the basis of the distances of 1st - 3rd quartile points of the relative cumulative frequency of stored measured values. CONSTITUTION: A decision reference value arithmetic unit 20 sets a decision reference value (weighted quartile standard) on the basis of hinge width 1 (distance from 1st quartile point to 2nd quartile point of stored measured values) and hinge width 2 (distance from 2nd quartile point to 3rd quartile point) obtained by a hinge width arithmetic unit 19, and the 1st quartile point and 3rd quartile point. An abnormality decision device 22 compares a measured value stored newly in a measured value storage device 18 with the decision reference value stored in a decision reference value storage device 21 to decide that a measured value meeting a condition of 1st quartile point - m × hinge width 1 < measured value < 3rd quartile point + m ×hinge width 2 (m: positive optional number) is normal.  Namely, the standard is weighted so that the normal range is wide in the direction wherein the frequency distribution is trailing.

Title: Production of fiber bundle pen point
Inventor: SHINOHARA YUTAKA
IPC: B43K1/12
Filed: 1987-12-29
Abstract: PURPOSE:To enhance ink-ejecting properties of a fiber bundle pen point, by a method wherein fibers aligned in order in the longitudinal direction in the condition where an adhesive applied thereto is not completely solidified are heat-treated by passing through a heated nozzle, and the adhesive is solidified by heating while maintaining the outer diameter of the resultant molded piece as it is. CONSTITUTION:Fibers with a fineness of not more than 3 deniers are aligned in order in the longitudinal direction, and are coated with an adhesive based on a thermosetting resin. The fibers are heat-treated by passing through a heated nozzle. The heating temperature and the velocity at which the fibers are drawn through the heated nozzle are so controlled that the solidification of the adhesive is stopped at an incomplete stage. As a result, the inside part of each of the fibers in the molded piece coming out of the nozzle is yet softer than the skin of the fiber. The molded piece is heat-treated to solidify the adhesive without affecting the diameter of the molded piece, thereby enlarging the variations in the density of the molded piece. The fiber bundle thus obtained is processed to appropriate length and shape to obtain a fiber bundle pen point having an extremely excellent ink-ejecting property.
