Patent JP-H0895420-A (JP)
Title: Electrophotographic device
Inventor: KATSUMATA YOSHIKAZU
IPC: G03G15/20
Filed: 1994-09-21
Abstract: PURPOSE: To reduce overshooting, that is, the transient sudden rising of surface temp. just after a roller stops, by controlling the surface temp. of the roller in consideration of the history of the surface temp. of the roller, stopping heating simultaneously with the rotation stop of the roller and resuming the control of the surface temp. of the roller after it starts to drop. CONSTITUTION: The PI control (temperature control for setting the output of a heater 115 in consideration of the history of the temp.) of the surface temp. of a heating roller is started by a temperature control part 1, at the same time as the power turning-on. When the temp. of the heating roller reaches 100 deg., a heating/pressurizing roller starts to rotate and when the surface temp. reaches 180 deg., the rotation is stopped to be in a stand-by state. At this time, the temperature control part 1 stops the PI control of the surface temp., to make the output of the heater 115 zero and when the surface temp. starts to drop, the control part 1 resumes the PI control.  In the completion of printing, when an ejection detecting sensor 119 detects the ejection of a paper sheet to the outside of a fixing device, the PI control is stopped and the heating is stopped and when an ejection detecting sensor 120 detects the ejection of the sheet to the outside of a machine, the rotation of the roller is stopped to be in the stand-by state.

IPC: G11B21/10
Filed: 1987-09-11
Abstract: PURPOSE:To improve the detecting ratio of a servo ID by providing a function for recognizing the servo ID part in a servo ID detector when an error in reading is present at the time of a reproduction. CONSTITUTION:In a reproducing circuit 5, a reproducing signal is outputted to a position error detector 7 and a reproducing pulse corresponding to the peak of the reproducing signal is outputted to servo ID detectors 6a, 6b. Even when there is the error in reading is present at the time of reproducing the servo ID parts 2a (A), 2b (B) by a magnetic head 4, the respective detectors 6a, 6b have the function for recognizing it as the servo ID part. At the time of detecting the servo ID part 2a (A), the detector 7 is triggered to output the pulse of a constant width. The reproducing signal is A/D converted at a constant interval by the trailing edge of this pulse and supplied to a controller 8. Thereby, the position of a stepping motor 9 is controlled so as to trace the magnetic head 4 on the track.

Title: Input tuning circuit
Inventor: HATASHITA HIROSHI
IPC: H03J5/24
Filed: 1988-09-12
Abstract: PURPOSE:To decrease a deviation in the band width even in the reception at a broad band, to prevent disturbance and to improve the loss characteristic by forming a 1st inductive impedance with series connection comprising one or two inductors or over and a varactor diode. CONSTITUTION:The inductive impedance whose inductance at a high frequency is smaller than the inductance at a low frequency is formed by series connection comprising stepup coils 12, 13 determinant of an input impedance and a varactor diode 8. As a result, the input impedance at a low frequency is decreased to widen the band width. Moreover, it is possible to increase the input impedance at a high frequency to widen the band width. Moreover, the tuning circuit and the output load are connected via the varactor diode 8 to lower the output impedance at a low frequency and to increase it at a high frequency. As a result, the band width deviation of the tuning circuit is reduced.
