Title: Temperature overrising preventing device for fixing device
Inventor: IKEDA YOSHITO
IPC: G03G15/20
Filed: 1992-04-27
Abstract: PURPOSE:To normally operate a temperature overrising preventing device even at the time of starting a fixing device, and at the time of reaching a normal state by shielding the surroundings except a side opposite to the fixing roller of an energizing interrupting member, with a shield member. CONSTITUTION:A thermal fuse 11 as the energizing interrupting member, is arranged at a small gap from the periphery of the fixing roller 1, and simultaneously, the surroundings except the side opposite to the fixing roller 1 is covered with a cover 20 as the shield member. Thus, the thermal fuse 11 is protected from an air current inside a fixing unit, such as convection by the heat of the fixing roller 1 and wind by an exhaust fan, and an environmental temperature (surface temperature) is prevented from being lowered. On the other hand, when the temperature of the fixing roller 1 reaches a prescribed one, even at the time of starting, the thermal fuse 11 is disconnected, the energization of a heater 2 is interrupted. Therefore. even at the time of starting the fixing device, or even in the normal state after the start, the temperature overrising preventing device 24 is normally operated.

Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a stable received image at all times by switching the time constant of a loop filter in a time base correction(TBC) processing circuit corresponding to the electric field state of an RF signal in the received image. SOLUTION: The output video signal of an RF signal receiving circuit 1 is outputted through signal processing circuits 2 and 3 on preceding and following stages. In this case, concerning the synchronization of the respective processing circuits 2 and 3, the time constant of the loop filter in a TBC processing means 4 is switched by a time constant switching means 8 corresponding to the detected result of an electric field strength detecting circuit 5 connected to the RF signal receiving circuit 1.  Thus, since the state of a received video signal or the electric field strength of a received RF signal is always detected and not only the time constant but also the gain and inclination of the loop filter in the TBC processing circuit are appropriately controlled corresponding to the detected result, reception trouble such as jitter or snaking is suppressed and images can be stably received at all the time.

Filed: 1989-04-28
Abstract: PURPOSE:To save, transmission data quantity without almost giving effect on a plotted figure and cursor operation by controlling data quantity to be sent in response to the distance between inputted coordinate data. CONSTITUTION:A display control section 9 displays a cursor to a position on a display device 10 represented by a coordinate data obtained from a mouse input interface 2 at a prescribed time interval according to a sampling clock 11. On the other hand, a coordinate information control section 3 calculates a distance R between the coordinate data and outputs a coordinate data to a transmission data conversion section 4 when the distance R is larger than the setting value and outputs the data while the inputted coordinate data is interleaved when the distance R is small, that is, the motion of the mouse 1 is slow. Thus, the transmission data quantity is reduce without almost giving the plotted figure and the motion of the cursor.
