Title: Variable gain amplifier
Inventor: MAEKAWA HIDESUMI
IPC: H03G3/30
Filed: 1983-10-31
Abstract: PURPOSE:To obtain a variable gain amplifier output without changing a DC voltage level at an output terminal by changing an emitter resistance of a differential amplifier comprising NPN transistor (TR). CONSTITUTION:The resistance value of N-channel junction field effect TRs (N- JFET) Q3, Q4 is changed by a signal of an AGC circuit 3 and an output voltage gain is obtained. As the N-JFET current voltage characteristic, a drainsource voltage VDS is increased and then a drain source current IDS is increased, saturated to a prescribed current value and the current saturation value is increased by increasing a gate voltage VG1. This invention uses the resistance change of the N-JFET on the principle above. Since the dynamic range is proportional to the emitter current and the emitter resistor, when the AGC is applied by increasing the emitter resistance, the dynamic range is widened. Then the dynamic range is widened more by the method changing the emitter resistance than the method changing the emitter current.

Title: Method for correcting peripheral length of endless steel belt
Inventor: HOSOMI KOJI
IPC: B21B5/00
Filed: 1984-09-28
Abstract: PURPOSE:To improve the correcting accuracy of the peripheral length of belt by stretching a multilayered body of endless steel belt around both driving and driven rolls and increasing the distance between the axes of them to reduce a correcting speed at an intermediate point before the final distance between them. CONSTITUTION:Said belt 30 is stretched around a driving roll 11 and a driven roll 12 to be freely circulated around them, and its peripheral length is corrected by providing a prescribed tension to the belt 30 with the aid of a hydraulic cylinder 31 used for adjusting the distance between the axes 13, 14 of both rolls 11, 12. At that time, a detecting means 40 for detecting said distance detects that the distance reaches a previously set intermediate point before a final point equivalent to the aimed peripheral length of belt 30 to reduce a correcting speed (i.e. the moving speed of cylinder 31) to a slow speed. Next, the tension provided to the belt 30 by the cylinder 31 is eliminated according to the detection of said final point of the distance. In this way, the accuracy of interlayer difference and the adjustment of peripheral length are achieved at the same time.
