Abstract: PURPOSE:To construct a series-parallel system driving circuit at a low cost with a reduced number of parts, by connecting between two divided coils through a diode, and employing complementary transistors. CONSTITUTION:A driving circuit is constructed which operates an electromagnet at a high speed by connecting two divided coils 4a, 4b to a power source 2 in parallel for a predetermined period of time after starting, and connecting both the coils 4a, 4b to the power source 2 in series after the predetermined period of time has elapsed. For example, a timing circuit, which is constituted by a resistor 7 and a capacitor 8 and adapted to supply current for a predetermined period of time after a switch 1 is made ON, is connected between the bases of a pair of transistors 6, 11 which are complementary to each other. A diode 12 is connected between the collectors of the transistors 6, 11. Both the transistors are made conductive through the timing circuit to connect both the coils 4a, 4b in parallel, and after a predetermined period of time has elapsed, both the coils 4a, 4b are connected in series through the diode 12. Diodes 9, 10 in combination constitute a discharging circuit for the capacitor 8.

Abstract: PURPOSE:To prevent glossiness from getting too much even in the case of switching from a full color image to a black-and-white image by providing a means for heating and melting toner transferred on a sheet in a 2nd fixing roller and either of 1st and 3rd fixing rollers. CONSTITUTION:The fixing in the case of forming the full color image which needs large heat capacity, for example, is performed at a fixing part formed of a press-contact part between 1st and 2nd fixing rollers 201 and 202 provided with heating means 204a and 204b, respectively.

In the case of switching from forming the full color image to forming the black-and-white image, the roller 202 which is heated too much in the case of forming the full color image is cooled by press-contacting with the roller 203, and temperature appropriate for forming the black-and-white image is attained instantly, so that the glossiness is prevented from getting too much just after switching.

When the updating coefficient is made into the prescribed value, the integrating time T1 and differentiating time TD are decided by the proportional band and oscillation period at such a time. Thus, the parameter can be automatically adjusted without making the plant into the non-control condition.

Abstract: PURPOSE:To eliminate interference without providing separately a subantenna by installing a horn for receiving interference wave from an interferring satellite at a position shifted from the center of a main reflection mirror. CONSTITUTION:A signal from a desired satellite 10 is focused at a position of a corrugated horn 21 and fed to a low noise amplifier 3 via a transmission/reception branching filter 22.

IPC: H04N5/14
Filed: 1993-05-06
Abstract: PURPOSE: To detect the detecting point of the edge of detected signals regardless of the edge shape of the detected signals by generating a zero-crossing point of the difference signal of the detected signals and a switching edge when the zero-crossing point is detected. CONSTITUTION: A first edge detector 12 generates a detected signal 12.1 when the detector 12 detects an undelayed signal and an edge detector 13 outputs a detected signal 13.1 having the same shape as a signal 12.1 has through a delay line 10. The delaying time of the line 10 is calculated so that the detected signals 12.1 and 13.1 may partially overlap each other. A subtractor 16 generates a difference signal from the two detected signals 12.1 and 13.1 together with the zero-crossing point at a signal edge detecting point. A zero-cross point detector 17 generates the zero-crossing point of the difference signal and, when the zero-crossing point is detected, a switching edge.
