Title: Operation of electric furnace
Inventor: YAMAOKA HIDEYUKI
IPC: C22C33/04
Filed: 1984-02-07
Abstract: PURPOSE:To attain the conservation of power of a hermetically closed type electric furnace in the preparation of alloyed iron, by blowing oxygen-containing gas into the stock material bed charged in the furnace and burning CO-gas generated in the furnace as a byproduct to preheat the charged stock material. CONSTITUTION:An opening part 8 is provided to the furnace lid 2 provided to the furnace main body 1 of an alloyed iron manufacturing hermetically closed type electric furnace and a gas blowing lance 9 is inserted into a charged stock material bed. Ambient temp. air and a proper amount of pure oxygen are simultaneously blown into the furnace body 1 from an air supply port 9-3 and a pure oxygen supply port 9-4. When CO-gas generated in the furnace as a byproduct rises while passes the charged stock material bed 7, said CO-gas is burnt by blown oxygen and the charged stock material 7 is preheated by the combustion heat. By this method, power consumed in raising the temp. of the stock material can be conserved.

Title: Disposal of dilute solution containing both metal halide and halic acid
Inventor: MIYAMOTO HITOSHI
IPC: C02F1/42
Filed: 1980-02-25
Abstract: PURPOSE: To extract a halic acid equivalent to a metal content in a waste solution which was used for pickling or rinsing steel articles, or which was discharged in a process of regenerating an ion exchange resin, by absorbing a metal in a metal halide with an H type ion exchange resin at the same time when the halic acid is extracted in a high purity from the waste solution without necessity of a heat source.  
     CONSTITUTION: A dilute solution containing both a metal halide and a halic acid is passed through an H type ion exchange resin to absorb the metal of the metal halide and to convert the halogen of the metal halide into a relevent halic acid. The cation exchange resin is regenerated with sulfuric acid. The generated waste solution is then electrolyzed to regenerate sulfuric acid. The regenerated sulfuric acid is cycled for reuse. The halic acid which is generated in the process, and the halic acid which was contained in the original waste solution are also extracted. In stead of sulfuric acid, an acid having an oxidation potential higher than an O 2  generating potential, e.g., phosphoric acid or nitric acid, may be used in combination with sulfuric acid.

Filed: 1990-02-02
Abstract: PURPOSE:To shorten lead-in time by switching a driving means which moves a pickup on an information recording medium till then in specified timing at a specified time before finishing rough retrieval to control a moving speed. CONSTITUTION:An AM detection circuit 1 detects an RF signal A and converts it into an envelope signal B, and a comparator A2 converts the envelope signal B into a digital signal C, then a comparator B2 outputs a digital signal E with the aid of the polarity of a tracking error signal D. An F-V converter 3 outputs a voltage in proportion to the frequency of the signal D and a latch 4 latches the output from the comparator A2 at the time when the output from the compa rator B rises. A polarity inversion circuit 5 inverts and outputs an output signal from the F-V converter 3 in accordance with the output signal F from the latch 4. A changeover switch 6 switches so as to input a rough retrieval system control signal in an amplifier 7 till the specified timing just before finishing the rough retrieval and input the output of the circuit 5 in the amplifier 7 till finishing the rough retrieval. Thus, the lead-in time is shortened.

Title: Dot area detecting method
Inventor: OUCHI SATOSHI
IPC: G06T7/00
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To detect a dot area accurately by detecting a center pixel or all pixels of a noted 2-dimensional area as the dot area, based on a relation between number of pole pixels of the noted 2-dimension area and number of pole pixels of surrounding 2-dimension areas. SOLUTION: An input image signal section 1 applies raster scanning to an original image to convert the image into a digital multi-gradation input image signal, consisting of a luminance signal and stores the signals by number of scanning lines required for the succeeding separate processing. A pole detection section 2 applies a matrix, consisting of M×M pixels, to each pixel of the digital multi-gradation input image signal from the input image signal section 1, so as to detect whether or not a center pixel of the matrix corresponds to a pole denoting a top or a bottom of the density change. A dot area detection section 3 discriminates whether or not all the pixels in a block belong to a dot area.  An area discrimination signal output section 4 provides an output of a discrimination signal that denotes it as to whether each pixel belongs to a dot area or to a line drawing area, based on the detected result of the dot area detection section 3.

Title: Batch process control system
Inventor: SHINOHARA SAKAE
IPC: G05B13/02
Filed: 1987-02-04
Abstract: PURPOSE:To improve the control performance as the processing frequency increases by providing a learning part which stores the control information obtained by the preceding processing and converts this control information so that it can be utilized for the next processing and carrying out the next processing based on said converted information. CONSTITUTION:The manipulated variable u(k) obtained in the preceding processing is stored and then filtered for production of uf(k) which is used as the reference value of the current manipulated variable. here an allowance range DELTAu of the current manipulated variable u(t) is set against the value uf(k). Then the manipulated variable u(t) calculated with use of the preceding parameter theta(t+dtau) is corrected so that the current manipulated variable is set within a range uf(t)+ or -DELTAu. The range DELTAu can be varied in accordance with the value of the deviation between the current control amount y(t) and the target value r(t). That is, the range DELTAu is reduced as said deviation is decreased. Thus it is possible to suppress the vibration of the variable u(t) as well as the vibration of controlled variable y(t). As a result, the batch process control performance is improved as the processing frequency increases.
