Title: Detector circuit for bubble memory
Inventor: TOYOOKA TAKASHI
IPC: G11C19/08
Filed: 1982-07-09
Abstract: PURPOSE:To eliminate the cause to level fluctuation, by adding a circuit setting a reference level discriminating 0, 1 of a detecting line signal in response to a detected output waveform, when only a reading signal corresponding to ''0'' is generated on the detecting line. CONSTITUTION:An output CONT of a control circuit 23 is set to an L level at the beginning of a threshold level set period, and an output RESET pulse of the circuit 23 is inputted to a threshold level set circuit 22. As a result, an output VTH of the set circuit 22 is set to an initial value. This initial value is set to a minimum level or below taken by an output of a differential amplifier 10 corresponding to a reading signal corresponding to ''0'' information. Thus, an output COUT of a comparator 11 is at H without fail. The COUT is inputted to the set circuit 22 through a gate 25 to increase the level of the output VTH by DELTAv according to the pulse. When the same operation is executed for plural number of times with the VTH set newly, the VTH is increased more than the output of the differential amplifier 10. Since no COUT is outputted after that, the VTH is kept to a prescribed level. An SET pulse is inputted from the circuit 23 to the circuit 22 at the end of the threshold level set period to increase the output VTH of the set circuit 22 by a required set value DELTAv'. The threshold level VTH set with above-mentioned process is held and the next readout is executed.

Title: Voltage controlled oscillator
Inventor: MASUDA YOICHI
IPC: H03B5/30
Filed: 1990-05-10
Abstract: PURPOSE:To set the sensitivity of an oscillating frequency optionally with respect to a control voltage by applying feedback control to the voltage controlled oscillator so that an amplification factor of one amplification factor variable amplifier changes in proportion to the control voltage and an amplification factor of other amplification factor variable amplifier changes in inverse proportion to the control voltage. CONSTITUTION:Since a collector current of a transistor (TR) 3 is a current resulting from the subtraction of a current flowing to a TR 4 from a collector current of a TR 1, the collector current is inversely proportional to the amplification factor of a lst amplification factor variable amplifier. Moreover, since a resistor 5 is connected between the collector of the TR 3 and a power terminal 6, the collector level of the TR 3 is inversely proportional to the collector current. When a control voltage fed to a control terminal 21 rises, the base level of the TR 3 is dropped and the base level of the TR 4 is increased. When the base level of the TR 3 is decreased, the collector current is decreased and the collector level is increased. Then the level is fed back negatively to an inverting input of a differential amplifier 20 via a low pass filter 22.

CONSTITUTION:A document S which is separated and sent out by a feed roller 10 and a reverse roller 13, wrinkles in the area corresponding to the width of the reverse roller 13, and in this condition, the peripheral speed of an edge part is faster than that of a middle part in a driving side roller 21 out of one pair of rollers 21, 22, because its outer diameter is increased toward its edge part from that in its middle part. Consequently, feeling action on the diameter S is stronger both edge parts then in the middle part, and as the result it a pulled toward the edge parts from the middle part. The larger DELTAE which is the difference between the diameter of the edge part and the diameter of the middle part in the roller 21, is the more effective it its as the measures against the wrinkles, but about 0.2-1% is preferable as DELTAE because it caused bias and the wrinkles when DELTAE becomes too large.
