Title: Combustion method
Inventor: KUSUMOTO SHIGEAKI
IPC: F23C99/00
Filed: 1986-01-24
Abstract: PURPOSE:To improve gas emissivity and to provide a combustion method having excellent combustion efficiency, by a method wherein a specified amount of gas, containing oxygen, in which gas having excellent gas emissivity is mixed in oxygen, is used as gas for combustion, and meanwhile, by using fuel having a less nitrogen content, a nitrogen partial pressure in a combustion device is decreased. CONSTITUTION:The tip of a piping 4 for feeding oxygen gas and the tip of a piping 5 for feeding fuel are connected to a burner 2, and the base end of the piping 5 is connected to a feed source for fuel containing nitrogen of 10vol% or less. A composition of mixed gas and oxygen gas, fed to the burner 2, is regulated by valves 3a and 4a so that a total sum of oxygen gas, carbon dioxide, and a moisture content is 50vol% or more and oxygen gas is 21vol% or more. Fuel fed to the burner 2 is burnt in the presence of oxygen gas in gas containing oxygen to heat a steel piece in a heating furnace 1. Thus, since fuel having a less nitrogen content is used, a nitrogen partial pressure in a combustion burner can be reduced, and heating efficiency can be improved.

Title: Kanji recognizing system
Inventor: SHIMA KIYOYA
IPC: G06K7/10
Filed: 1988-01-27
Abstract: PURPOSE:To correctly recognize a KANJI (Chinese character) in a short time by alternately disposing black points and white points on the upper side and the left side of an information element, disposing the white points on a lower side and a right side and reading a code on which a point representing information is disposed by an image scanner. CONSTITUTION:In order to obtain the entry position of the information element, the positions Xa, Ya,...Xd, Yd of the points (a), (b), (c), (d) of the four corners of an external frame are obtained to obtain the coordinates of the points 11, 12, 21, 22 of the reference of four bits. The widths of the external frame are respectively subtracted from the distance of the X axis direction of the point (a) and the point (c), and the point (b) and the point (d) and averaged to have the length of the X axis direction occupied by a piece of information and they are two columns, so that they are divided equally into two to obtain the width Xs of the piece of information. On a Y axis, Ys is similarly obtained. The width of the information obtained in such a way is added to the coordinate Xa, Ya of an origin, thereby, the coordinate of the reference of the information is obtained. However, when the number of the bits of a the information element is increased, the position detecting error of the information element is increased. Then, as one part of the external frame, the black points and the white points are alternately disposed to measure the position of the black points, thereby, more correctly obtaining the position of the information.

Abstract: PURPOSE: To make it possible to output extremely smooth half tone by turning on and off a semiconductor laser by several kinds of high-frequency pulses different in frequency.  
     CONSTITUTION: An inputted picture signal is amplified at 10 up to a stated level. On the other hand, high-frequency pulse 19 from high-frequency oscillator 15 is divided in divider 12 and the output of amplifier 10 is A/D-converted in A/D converter 11 by divided sampling pulse 20 and inputted into digital value comparator 22.
