Title: Image forming device
Inventor: INUZUKA TSUNEKI
IPC: G03G15/08
Filed: 1979-05-17
Abstract: PURPOSE:To avoid the complexing of the operating part by displaying the toner shortage in the developing device and the overflow of the toner recovery case by a common display device in a dry type electrophotographic copier or the like. CONSTITUTION:A residual toner amount detecting element 61 and overflow detecting element 62 detect the toner level in a case from the presence or not of the toners interposing between lamps and photo detectors and output the signals TEP, OVF respectively. When the toners in the developing device during copying become less, the signal TEP is output by way of an operational amplifier Q50. The signal thereof lights a toner-absence display device 48 by way of a gate G61. When the toners in the toner recovery case increase and become close to an overflow state, the signal OVF is output through an operational amplifier Q51 to light the toner-absence display device 47 through the gate G61 in the same manner as with the TEP. In this case, it may be possible to make the displaying differing from that of the TEP of lighting the device by letting the device flicker.

Title: Phase-locked loop
Inventor: BAASU ARAN KIYANFUIIRUDO
IPC: H03L7/087
Filed: 1993-02-24
Abstract: PURPOSE: To prevent noises in a frequency error signal from causing jitters to a phase of a signal from a variable oscillator by selectively eliminating the frequency error signal from the variable oscillator, when a PLL system reaches a frequency-locked state. CONSTITUTION: A phase error signal, which is fed from a scaler 96 and a frequency error signal fed from a 2's complement circuit 88, are combined by an adder 94 to control a voltage-controlled oscillator VCO 86. The frequency error signal is selectively fed to an adder 94 via a gate circuit 90 controlled by an unlock detector 100. That is, when the PLL system reaches substantially a frequency lock state, the gate 90 inhibits the passing of the frequency error signal. Thus, noises in the frequency error signal fed from the two complement circuit 88 does not cause jitters to a phase from a signal from the variable oscillator.

Title: Level detecting circuit
Inventor: OOSAWA MITSUO
IPC: G01R19/00
Filed: 1983-04-07
Abstract: PURPOSE:To detect levels of many power source circuits, etc., securely at a high speed by providing plural current mirror circuits connected between plural reference power sources and a constant current source, and turning off the current mirror circuits when an input signal exceeds the reference level of the power sources and generating a detection signal. CONSTITUTION:When the input signal from the side of a connection point P exceeds a reference voltage + or -V1, a TRQ10 or TRQ11 turns off and the voltage of a resistor R45 drops to a zero level. Similarly, when the input signal exceeds a reference voltage + or -V2, the voltage of a resistor R46 goes down to the zero level. Namely, when the level of the input signal is within the reference range, high-level control signals SCA and SCB appear at the collector sides of TRs Q10 and Q12, but when the level of the input signal exceeds the reference voltages, the level is inverted and low-level control signals SCA and SCB appear at the collector sides of the TRs Q10 and Q12. Namely, current mirror circuits 10- 13 operate as gate circuits and operate as original current mirror circuits when the input signal is within the reference level range.

IPC: B65H23/195
Filed: 1982-04-13
Abstract: PURPOSE:To prevent the application of the abnormal tension to a tape regardless of the winded tape diameter, by detecting the value of the tape wind diameter and then varying the maximum torque which can be delivered from a reel motor at each time. CONSTITUTION:The speed of a tape 1 is detected by a photointerrupter 6, and this detecting signal is fed to a speed control circuit 11 via a waveform shaping circuit 10. The circuit 11 produces a speed error signal from a speed reference signal and a speed detecting signal and feeds it to a torque control circuir 15. The circuit 15 varies the maximum torque of a reel motor 7 that can be obtained by a motor driving circuit 12 in response to the value of the tape wind diameter R of a take-up reel 3 on the basis of the information obtained via the photointerrupter 9 and a tape wind diameter detecting circuit 14 and although the error signal swings to the full within the working range. This prevents the application of the abnormal tension to the tape 1 regardless of the value of the diameter R.

Title: Original reader
Inventor: SAITOU TSUTOMU
IPC: H04N1/04
Filed: 1979-05-21
Abstract: PURPOSE:To remove or lessen an influence of stary light by constituting an arithmetic circuit so that an electric signal from a photo detector will selectively be added corresponding to the size of an original to be read. CONSTITUTION:The read original 13 samll in size, an input from key switch 22 opens switches 181 and 183 and closes 182. Then, when a laser beam stays near both X-directional end parts of an original holding part, stray light strikes optical fiber element groups 151 and 153 because of no original and photoelectric converting elements 161 and 163 output an electric signal corresponding to the quantity of the stray light. However, since switches 181 and 183 are left open, the outputs of amplifiers 171 and 173 are never input to analog adder 19. Next, when the laser beam is in the region of original 13, the laser beam strickes optical fiber elememt group 152 by scattering and reflecting from original 13. Therefore, an electric signal corresponding to shade information on original 13 is input to adder 19. On the other hand, although the stray light strike element groups 151 and 153, its electric signal is never input to adder 19.
