Title: Integrated circuit
Inventor: NAKAJIMA TOSHIO
IPC: H01L31/04
Filed: 1983-09-22
Abstract: PURPOSE:To obtain an IC which can have the stable operation even when it is driven with a solar battery, etc. by using a voltage deciding circuit to decide the power supply voltage and stopping the supply of clock pulses to the IC when the power supply voltage becomes less than a prescribed level. CONSTITUTION:A voltage deciding circuit 2 detects the voltage value of a power supply terminal 1, and an output 3 is changed to a low level from a high level when the power supply voltage is lower than a prescribed level. An AND gate 4 controls the supply of clock pulses and decides the supply of the output of a clock oscillator 5 to a circuit 6. The output 3 is set at a low level by the function of the circuit 2 in case the power supply voltage of the terminal 1 is lower than a prescribed set voltage. Thus the output of the oscillator 5 is cut off by the gate 4 and not supplied to the circuit 6. A runaway state which causes an abnormal current does not occur if the supply of clock pulses is stopped. Then a low current consumption state is maintained. Thus it is possible to obtain an IC which can have the stable operation even when it is driven with a solar battery, etc.

Abstract: PROBLEM TO BE SOLVED: To eliminate the occurrence of output current distortion caused by on-delay time, by computing a PWM waveform taking on-delay compensation into consideration from the output signal of an on-delay compensation timing computing section and outputting the computed waveform to a power inverter. SOLUTION: A frequency analyzer section 6 detects a frequency component which is twice or odd number times as high as an operation command frequency and an on-delay compensation timing computing section 7 changes the on-delay compensation timing with the zero-crossing point as the center, so that the frequency component can become the minimum after the change directions of the detecting levels of both frequency components are confirmed. Then, a waveform computing section 8 drives an induction motor with a PWM waveform, taking the on-delay compensation timing into consideration.

Title: Denitrification control of denitrification device
Inventor: ARAKI KOJI
IPC: B01D53/74
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To denitrify exhaust gas by making a denitrification rate accurately constant, if there is a sharp load variation. SOLUTION: An addition molar ratio m2 is sought by adding a molar ratio correction value mc which corrects a rate of denitrification so that the rate is constant, if there is a load variation, to a molar ratio ml complying with a fuel demand 2. Further, an ammonia flow rate is controlled so that a calculated quantity of ammonia 6 obtained by multiplying the addition molar ratio m2 by a total quantity of NOX 5 and an actual quantity of ammonia 8 show a deviation of O. On the other hand, a residual quantity of ammonia 27 obtained by subtracting the rate of denitrification 23 obtained based on the actual quantity of ammonia 8 from a value 1 is multiplied by a differential rate of variation 29 in NOX at the entrance which is obtained by differentiating a rate of variation 11 in NOX at the entrance to seek a correction value 31.  In addition, an estimated rate of variation 33 in NOX at the exit obtained by adding the correction value 31 to a rate of variation 12 in NOX at the exit and the rate of variation 11 in NOX at the entrance are used to seek an actual rate of denitrification 14. Further, the molar ratio correction value mc is sought based on a deviation between the actual rate of denitrification 14 and a set rate of denitrification 16.

Title: Magnetic disc device
Inventor: TAKAHASHI KAZUJI
IPC: G11B21/08
Filed: 1985-08-13
Abstract: PURPOSE:To suppress the increase of the burden in a system side by providing a control means which changes the extent of movement of a magnetic head, which corresponds to a signal which instructs the magnetic head to move for one track, in accordance with the input of an external control system. CONSTITUTION:In case of the change of the recording density, a change signal is switched to the high/low level at a desired timing. When 'single' is selected as the density, excitation is switched in two-phase excitation each time when a head seek signal is inputted. When the recording density change signal is switched to 'double', a switching signal is sent to a step motor control part 18 from a drive control circuit 20 at a time T1 when the track where the reference position of head seek is compensated is detected, and hereafter, excitation is performed twice per one step signal in two-phase excitation, and the extent of movement of the head per one head seek is doubled. That is, the track pitch for 'double' is two-fold track pitch for 'single', and the recording density for 'double' is reduced to a half. Thus,the recording density is changed freely even during device operation without increasing the burden of the control system.
