Title: Control system for servo circuit
Inventor: CHIYUUNO MASARU
IPC: H02P7/288
Filed: 1979-08-24
Abstract: PURPOSE: To ensure an easy control for the loop gain of the servo circuit having a constant speed control to an optional value, by detecting the counter electromotive force of the DC motor and then forming a negative feedback control loop.  
     CONSTITUTION: A control is secured for the resistance side of the 3rd resistance R 3  by the serial connection between the fixed resistance r 3 ' and the variable resistance r 3 ". During this control, the parallel connection of the fixed resistances r 2 ' and  r 2 " is secured for the 2nd resistance R 2  of other resistance side to obtain R 2 .  Then based on the loop oscillation method, a control is given to variable resistance  r 3 ' to obtain R 3 /R 2 ≈R a /R 1 . After this control, the r 2 " is made disconnective to  secure R 2 =r 2 ' to complete the control. Here R 1  is the 1st resistance and R a  is the  armature resistance respectively. In this control system, whether the counter electromotive voltage control system has the loop oscillation or not is checked by giving  an observation of the waveform by an oscilloscope to either one of the emitter (a)  point of the transistors 3 and 4, the output terminal (b) point of the operational  amplifier 2, the reverse-phase input terminal (c) point of the amplifier 2 and the  positive-phase input terminal (d) point of amplifier 2.

Title: Image fixing device
Inventor: KAMEI TATSUO
IPC: G03G15/20
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To constitute a simple means for detecting whether a fixing cleaning part is fresh one or not, by incorporating a temperature fuse into the fixing cleaning part and detecting whether the temperature fuse has been blown or not, thereby judging whether an oil roller is unused or not. SOLUTION: When a user replaces a fixing cleaning part 18 with a fresh one, the periphery of the fixing cleaning part 18 has such a low temperature that one can touch it. At least it is not such a high temperature exceeding 100 deg.C. At the time, a temperature fuse 16 attached to the unused fixing cleaning part 18 is not blown and has a sufficiently small resistance value in comparison with that of a resistor. Subsequently, when the temperature of a heat roller 11 is made high in order to carry out an image fixing operation, the temperature fuse 16 is also heated to a high temperature, is blown at the end and becomes released. Therefore, the simply monitoring of a voltage makes it possible to judge whether the attached fixing cleaning part 18 is unused one or not, that is, an oil roller 15 is impregnated with sufficient oil or not.

Abstract: PURPOSE:To shorten the time required for anomaly detection, by switching current and auxiliary units when the time change rate of the output level of the LPF exceeds a fixed value in respect to current and auxiliary units for fundamental frequency generation dependent upon a PLL circuit. CONSTITUTION:In current and auxiliary fundamental frequency generating units consisting of main oscillators 1 and 1' and PLL circuits 2 and 2', outputs of LPFs 22 and 22' are subjected to A/D conversion by converters 6 and 6' and are stored in memories 7 and 7'. Digital values stored in memories and digital values of A/D converters are compared with each other by comparators 8 and 8'. If memories and comparators use fundamental frequencies fi and fi' of main oscillators as sampling pulses, comparators detect equivalently the difference between two digital values different in period, namely, the time change rate of the LPF output signal level. In case that this difference exceeds a fixed value, change-over switches 3 and 3' are switched through control circuit 5 to perform switching from the current unit to the auxiliary unit or from the auxiliary unit to the current unit.
