Title: Signal reproducing method for recording medium
Inventor: MITA SEIICHI
IPC: G11B20/14
Filed: 1993-01-28
Abstract: PURPOSE:To make the binarization of a signal at the same slice level possible by replacing a reproducing signal having the fluctuation of a low frequency component with another signal in an area other than a demodulation area, a non-recorded part and a relatively long default signal area. CONSTITUTION:The default and non-recorded areas of the reproducing signal are detected by a waveform shaping circuit 9. The output (c) of a DC correction circuit 2 is inputted to a signal compensation circuit 3 and replaced with a compensation signal (d) whose average potential is equal to a reference voltage Vr before a reproducing area, the non-recorded area in the reproducing area being reproduced and in the relatively long default signal area. Also even in the condition that a read gate (e), that is, a signal reproducing area from a system controller 14, is negative, when the non-recorded area being reproduced and the relatively long default signal area are detected by default detection circuits 10 and 11, it is replaced with the compensation signal (d) by the default detection signal (f) of the circuits 10 and 11.

Title: Method for descaling hot rolled silicon steel plate
Inventor: TAKEDA SUNAO
IPC: C21D9/46
Filed: 1992-01-27
Abstract: PURPOSE:To perform descaling by means of continuous annealing and pickling treatment at the prescribed plate passing velocity by controlling the annealing atmosphere at the time of hot rolled silicon steel plate annealing, applying mechanical descaling, and regulating the immersion length in a pickling solution. CONSTITUTION:A silicon steel sheet is produced by hot-rolling a silicon steel slab, subjecting the resulting hot rolled plate to continuous annealing and to pickling, and then passing the plate through manufacturing stages including one or two cold rolling stages. At the time of performing hot rolled plate annealing, the air ratio in the gas combustion atmosphere in the temp. region where steel plate temp. becomes >=400 deg.C is controlled, by which the scale thickness of the hot rolled plate after combustion is regulated. Subsequently, mechanical descaling is done and descaling is allowed to proceed to the prescribed scale thickness. Then, the immersion length of the hot rolled plate in a pickling solution is regulated and the amount of descaling at the time of pickling is regulated. By this method, continuous pickling for plural types of steel can be done at the velocity equal to the annealing velocity.

Abstract: PURPOSE: To easily constitute a virtual compensation capacitor in an IC by making the capacitor usable as the on-chip frequency compensating constitution of a switching regulator by using a negative feedback operational amplifier. CONSTITUTION: The output of an operational amplifier 22 is returned to its inverted input. When the inclination of an open loop gain is driven with a signal which operates at a frequency of -dB/decade at a terminal 24, an equivalent capacitor 20' is formed at the noninverted input of the amplifier 22. Therefore, a capacitor multiplying circuit can easily simulate a capacitor having a value of the order of several hundreds of nanofarads. This circuit becomes applicable as part of loop compensation to the amplifier of a switching regulator.

Inventor: TAKAHASHI SUSUMU
IPC: H03L7/08
Filed: 1982-01-29
Abstract: PURPOSE:To realize a stable PLL operation to a signal of a random cycle, by using a voltage control oscillator which receives a phase control with an exclusive OR between the latch output of an input signal and the input signal and at the same time has a latch operation with an oscillation output. CONSTITUTION:An input signal (a) having a random cycle and supplied through an input terminal 1 is applied to a data input D of a latch circuit 2 as well as to a double input exclusive OR circuit EX-OR3. An output (b) of a voltage control oscillator VOC performs a latching operation. The difference of phase between the signal (a) and the output signal (c) of the circuit 2 is applied to a VCO5 via an LPF4 to control the oscillating frequency of the VCO5. In a steady state the VCO5 is locked when a cycle of the output (b) is equivalent to a clock period T. Therefore the pulse width of the output (b) is set at 1/2T in the steady state. Then the signal (a) has a delay phase compared with the output (b). Thus the pulse width of a phase difference (d) is reduced, and a control is given to  delay the phase of the output (b).

IPC: B67D7/42
Filed: 1991-01-11
Abstract: PURPOSE:To make a common tube serve both as a vapor sampling tube for determining a fuel type and a tube for detecting a full tank. CONSTITUTION:A gas detector and a pressure detector are connected in the middld of a tube whose tip is connected to an open hole 24 at the tip of a dispensing tube of a fuel feed nozzle and rear end is connected to a negative pressure generator. When the negative pressure generator is actuated to pull a fuel feed lever 20, a stop valve 26 opens to have a pressure sensor signal varied and also vapor in an automobile fuel tank is fed into a gas sensor. Thus a fuel type in the automobile fuel tank can be determined. If fueling is started in this state and fuel is supplied up to the vicinity of a fuel port, the open hole 24 is closed by the fuel so that the signal from the pressure sensor again varies. With this change in the signal from the pressure sensor, a full tank is determined. Thus a single vapor sampling tube can both determine the fuel type and detect the full tank.
