Title: Method of measuring deviation of azimuth angle
Inventor: MIZUNO YOSHIO
IPC: G11B5/455
Filed: 1993-03-30
Abstract: PURPOSE:To achieve an accurate and handy measurement of a deviation of an azimuth angle of a magnetic head. CONSTITUTION:A sweeping signal with the frequency thereof varying from 0Hz to several MHz is recorded on one track with a known track width W thereof using a magnetic head with an azimuth angle thereof known as differing from the azimuth angle of a magnetic head 15 to be measured to prepare a reference tape for measurement. Then, the reference tape is set on a magnetic reproducer carrying the magnetic head 15 to be measured to reproduce. A reproduction signal of the sweeping signal is outputted from the magnetic head 15 to be measured. But, when a deviation of the azimuth angle and the frequency of the sweeping signal in the recording and reproduction meet a specified relationship, an azimuth loss increases. The deviation of the azimuth angle of the magnetic head to be measured can be measured from a suppressing point of the reproduction signal. At this point, as reproduction is performed during the stoppage of the tape, the effect of disturbance caused by the running of the tape is reduced thereby achieving accurate measurement.

IPC: H04N1/401
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To eliminate unevenness of density by measuring the density of an image at a plurality of points for one pixel of a thermal head, determining the density data for each pixel of the thermal head from the variation of measurements and setting correction conditions, and then correcting the image data for recording an image depending on the correction conditions. SOLUTION: An image (hereinafter referred to chart) for setting correcting conditions is recorded at a constant density by recording a black pixel extending in the subscanning direction in the vicinity of the opposite ends in the main scanning direction and supplying a pixel data of same heating energy to all other pixels. A densitometer is then scanned in the main scanning direction and the density of the chart is measured linearly over the entire region. Density is measured at a plurality of points for one pixel and the mean value of measurements is calculated. Subsequently, correction conditions are determined as the density data of each pixel and set at a shading correcting section 80D in order to correct shading. According to the arrangement, correct shading correcting conditions can be set for all pixels.

Title: Inhibiting method for oxidation and polymerization of furfural and its derivative
Inventor: GAJI BII DEITSUKAKIAN
IPC: C10G21/16
Filed: 1995-03-29
Abstract: PURPOSE: To inhibit the oxidation and polymerization of a furfural derivative by adding a dialkylphenylenediamine to the furfural derivative as an inhibitor.  
     CONSTITUTION: An inhibitor expressed by the formula (R 1  and R 2  are each a 2-4C alkyl) is introduced into furfural or its derivative at a concentration of 5-1,000 ppm while keeping the acidity of the furfural or its derivative to about <0.20 mgKOH/g. The control of the acidity is preferably carried out by intermittently introducing a liquid amine such as ethylamine. The introduction of the inhibitor can be carried out during or after the production of furfural or before the transportation and/or storage of furfural. Furfural is useful for the solvent purification process to extract a component from a lubrication oil. Other examples of the inhibitor are diarylphenylenediamine, dialkylnaphthalenediamine and diarylnaphthalenediamine.
