Title: Heat fixing device
Inventor: YAMASHITA KEITAROU
IPC: G03G15/20
Filed: 1983-03-18
Abstract: PURPOSE:To form a heat fixing device where a practically uniform heating temperature is obtained throughout the overall length of a heat roll by extending an insulating layer on the outside circumference of a metallic hollow core up to shaft part of the hollow core. CONSTITUTION:When a heat roll 1 and a pressure roll 2 which are pressed to each other are rotated by a driving means such as a motor, a gear, or the like and, for example, a commercial AC voltage is to a feeding brush 13 brought into contact with electrodes 9a and 9b, a current is flowed to a resistance heating body layer 8 to heat it. When the surface of the heat roll 1 reaches a prescribed fixing temperature, a supporting material 16 holding a toner image 15 is allowed to pass between the heat roll 11 and the pressure roll 2 to obtain a fixed image. By this heat fixing device, the radiation from the shaft end part of the heat roll 1 to the outside of the fixing device is suppressed considerably by the heat insulating effect of an insulating layer 7 because the shaft end part of the heat roll 1 is supported on a bearing 3 through the insulating layer 7, and thus, the temperature distribution in the axial direction on the surface of the heat roll is kept uniform practically.

Title: Series lighting circuit wire-core breaking detector
Inventor: NARITA KAZUTOYO
IPC: H05B37/03
Filed: 1989-02-28
Abstract: PURPOSE:To permit detecting the position of a wire-broken lamp so as to attempt improvement in the efficiency of lamp maintenance and inspection operations by short-circuiting the secondary winding side of an insulating current transformer for a wire-core-broken lamp, and then canceling the short-circuited condition of each lamp after the passage of a time set differently at every lamp. CONSTITUTION:With the breaking of a wire-core in a lamp L1, a terminal unit R1 short-circuits the secondary winding side of an insulating current transformer CT1 after the passage of a given waiting time. In the meantime, when a wire-core breaking occurrence judgment unit 6 judges the occurrence of a broken wire-core by the rise waveforms of both an output current and an output voltage from a constant-current power unit 2, it varies the output waveform of the unit 2 via a power source control unit 8 during the waiting time. On detecting a change in the output waveform of the unit 2, the terminal unit R1 cancels the short-circuited condition of each lamp after the passage of a given time set differently at every lamp. The judgment unit 6 detects this cancellation and subsequently the control unit 8 measures the time necessary until this change of the waveform is undergone after the passage of the time when the output of the power unit is originally varied so that a wire-core breaking position judgment unit 9 judges the position of a wire-broken lamp. The efficiency of lamp maintenance and inspection operations is therefore improved without needing any walk-around inspection.

Title: Temperature controller for fixing device
Inventor: YOTSUKAICHI KEIJI
IPC: G03G15/20
Filed: 1987-03-02
Abstract: PURPOSE:To prevent a fixing device from being overheated, by storing abnormality detecting information, when the abnormality of a temperature sensor is detected. CONSTITUTION:When a power source switch 5 is turned on, and power conduction is started, a warm-up timer 4 starts its operation, and until the warm-up time elapses, a 'H' signal is outputted to an AND circuit 7. The circuit 7 outputs a 'H' signal so as not to operate an abnormality detecting circuit, and inputs it to a temperature control circuit 8. The circuit 8 outputs a 'L' signal. In this case, since a timer 10 and a storage element 11 are not operating, an OR circuit 13 outputs 'L', and a solid-state relay 14 becomes on, therefore, a heat source 1 becomes on. Subsequently, when the abnormality of a temperature sensor is detected, the heat source 1 is turned off quickly, so that the heat source 1 is not turned on even by an operation such as returning-on etc. of the switch 5 and a door switch 6. Also, after the abnormality has been detected, when the cause of disconnection of a thermistor 2, etc. is eliminated, its abnormality detection is released automatically, when a prescribed time elapses. Also, a state of the abnormality detection is released by only depressing a prescribed key 15 without waiting for the prescribed time.

Title: Frequency modulation method for crystal oscillator
Inventor: OKAZAKI KUNIO
IPC: H03B5/32
Filed: 1986-03-04
Abstract: PURPOSE:To apply frequency modulation directly to a signal only by a crystal oscillation circuit having high stability such as a Pierce oscillation circuit without using an accessory circuit by sending a modulation wave whose amplitude is converted into a mechanical amplitude by a moving coil to a crystal vibrator via a damper. CONSTITUTION:An electrode is fitted to the crystal vibrator 1, which is connected to a crystal oscillation circuit such as a Pierce oscillation circuit to apply oscillation. In impressing a signal current such as a voice current to a moving coil 3, the moving coil 3 is vibrated by the mutual action of the magnetic force with a permanent magnet 4. Compression and expansion are executed for the crystal vibrator 1 between dampers 2a and 2b through said vibration, the mass of the crystal vibrator 1 is changed by the compression and expansion, resulting that the oscillated frequency of the crystal oscillation circuit is changed. So long as the change depends on the amplitude of the signal current such as the voice current, the oscillated output of the crystal oscillation circuit is subjected to frequency modulation.

Abstract: PURPOSE: To facilitate narrow band spectrum analysis of repetition signals. CONSTITUTION: In a narrow band spectrum analyzing device for separating and analyzing the selected segment of periodic signals, the signals to be analyzed are digitalized by an analog-to-digital converter 31. A gate generator 36 is so constituted as to trigger at a specific part of signal waveform and to identify the start and end of the selected segment. The gate generator 36 generates a digitalized gate sequence over the period of the segment. The envelope of this sequence can be formed in rectangular shape, ideally can be made the envelope of a specific window function. The digitalized signals are then multiplied by the gate sequence, and the multiplied output is supplied to a signal processor to perform narrow band spectrum analysis.  A DC component in the selected segment is thereby eliminated completely before multiplication so as to reduce the possibility of presence of a spectral term to be a false signal in the output of the processor. This spectrum analyzing device is provided with a means for reasoning the component amplitude of the continuous signals in case of supposing that the signals in the segment period is part of the continuous signals at the root.
