Filed: 1989-02-01
Abstract: PURPOSE:To produce steel plates having an excellent surface property and improve the production efficiency by a method wherein a reduction ratio are measured which represent partial pressure ratios of the reducing gas components to the non-reducing gas components in the atmosphere in a furnace, and the excess air ratio is controlled so as to maintain the reduction ratio within a constant range. CONSTITUTION:Reducing gases of CO and H2 and non-reducing gases of CO2 and H2O are detected by detecting elements of a reduction ratio meter 9 in a direct firing furnace 1, and a reduction ratio is measured as the concentrations of reducing gas components. Next, an air ratio is obtained by an excess air ratio conversion device 10 which converts the obtained reduction ratio into an excess air ratio according to the data on combustion gas composition, and an excess air ratio is obtained from this converted air ratio and a target air ratio by an excess air ratio controller 11. On the other hand, the outlet temperature of steel plate 3 is detected by a steel plate thermometer 8, and an air feed ratio is calculated from the measured temperature and a target temperature by a steel plate temperature controller 12. The calculated air feed ratio is input to an air flow controller 13, and an air control valve 14 is operated so as to control the air feed ratio. By maintaining the reduction ratio within an adequate range, and oxide film thickness on the surface of the steel plate can be controlled at a low value and an excellent surface property can be obtained.

Inventor: TACHIBANA YASUO
IPC: H03H17/02
Filed: 1994-02-18
Abstract: PURPOSE:To make a calculation time per sample period independent of the number of taps by forming a spectrum analyzer with a narrow band digital filter. CONSTITUTION:The spectrum analyzer is formed with a narrow band finite impulse response type digital filter in which a coefficient for each tap is given as a product among a trigonometric function, a complex variable exponential function and a real coefficient power whose absolute value is the '1' or below. An input signal is given to synthesis filters 1-3 and output signals from the synthesis filter group are all fed to a frequency separator 4, from which a spectrum separate signal resulting from multiplication between said received signal and a frequency separate matrix is outputted. Thus, a calculation time per one sample period is made independent of the number of taps and indepedent of the initial conditions of the filters.

Filed: 1988-02-01
Abstract: PURPOSE:To realize low power consumption and a low cost by a method wherein a closed magnetic circuit is formed by using a yoke and an armature without containing a permanent magnet part when a coil is excited. CONSTITUTION:When electricity is applied in such a way that magnetic flux flows in a path PHI2 (an arrow with a broken line) in a direction opposite to a direction of magnetic flux in a non-exciting path PHI1 flowing in a moving part 9, one magnetic path is as follows: the moving part 9 of an armature 2 zeta a gap G2   a magnetic pole part 13   a yoke 3   a permanent magnet 5 zeta an auxiliary yoke 4   its other end 14   a gap G3   an armature 10   the moving part 9. The other magnetic path is as follows: the moving part 9   the gap G2   the magnetic pole part 13  the yoke 3   a magnetic pole part 12   a gap G1   the armature 10   the moving part 9. In the former magnetic path, the magnetic flux of the permanent magnet 5 and the magnetic flux of a coil 1 are offset; the magnetic flux in the latter magnetic path is overlapped with the magnetic flux of the permanent magnet 5 at the gap G1. As a result, the gap G1 becomes small as the armature 2 approaches the magnetic pole part 12. Finally, the gap G1 results in a closed state; a magnetically closed loop which does not pass through the permanent magnet 5 and the gap is formed by the latter path.
