Abstract: PURPOSE:To improve the detecting performance for jams by disposing a sensor unit wherein plural pieces of light emitting elements and one photodetector are combined to one body in proximity to the surface of a photoreceptor in the position after separation of recording paper. CONSTITUTION:An IR light emitting diode 20b for detecting toner density, a visible light emitting diode 20c for detecting jams, and a phototransistor 20d which detects the light emitted from the diodes 20b, 20c and reflected from a small piece for reference density and outputs as electric signals are embedded respectively at prescribed angles in a supporting body 20a for forming a sensor unit 20. Then the space for mounting and the number of constituting parts are reduced and since visible light is used for detection of jams, the difference in the output levels of the photodetector when a jam is detected changes largely as compared to the case in which IR is used, whereby the detecting performance for jams is improved.

Title: Switching power unit
Inventor: HENMI TOKUYUKI
IPC: H02M3/155
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To stabilize the boosted voltage from a switching power unit and the operation of a control system, by rectifying the boosted voltage by connecting diodes and capacitors in the output section of a charge pump circuit. SOLUTION: The turn-on/off duty ratio of a switching transistor(TR) 3 is set at <100%. When a switching power unit is starte, a voltage is applied to a control section 25 from an input power source 1 through diodes 10 and 11 and a circuit is operated. As a result, the TR 3 is turned on. The source voltage of the TR 3 is boosted and the cathode-side voltage of the diode 10 is boosted. When the TR 3 is turned off, a diode 4 is turned on and the source of the TR 3 is connected to a O voltage. As a result, the diode 10 is turned on and charges a capacitor 15 and the cathodeside voltage of the diode 10 becomes nearly equal to the input voltage. When the cathode-side voltage of the diode 10 is rectified by means of the diode 11, a capacitor 13 is stabilized at a voltage which is about twice as high as the input voltage. Thus a switching power unit can make stable boosting operations.

Abstract: PURPOSE:To discriminate the frequency of an input signal accurately by passing the frequency of a difference component in the multiplication output of a specific signal through a band-pass filter and deciding whether the level of the passing signal is larger than a reference level or not. CONSTITUTION:The input signal is multiplied by the specific signal generated by a signal generating means and the sum component of and difference component between the frequency of the input signal and the frequency of the specific signal by the multiplication are obtained as the multiplication output of a multiplier 24. For example, the frequency of the difference component as one multiplication output is passed through the band-pass filter BPF30 and a level decision means (AM detector 32 and a comparator 34) decides whether the level of the passing signal is larger than the reference level or not. Then, a frequency decision means (frequency counter 40 and coincidence decision circuit 42) decided whether the frequency of the passing frequency is equal to a set frequency or not and the frequency of the specific signal generated by the signal generating means is varied according to those level decision output and frequency decision output, thereby deciding the frequency of the input signal from the coincidence or constant relation between the frequency and the frequency of the input frequency.

Abstract: PURPOSE:To enable the control in the plate shape of a rolling stock corresponding to the rolling conditions by moving a cross point onto the line center by operating each one side cross device of the upper and lower rolls and by forming the crossing state of the upper and lower rolls. CONSTITUTION:A roll cross state is generated with one side cross method by moving the hydraulic cylinder plunger 4, 9 for crossing at the work side to the outlet side on the upper roll and by moving the hydraulic cylinder plunger 24, 25 for crossing at the driving side to the outlet side on the lower roll in the cross mill.

Accordingly the cross point obtains the roll gap change in the roll axial direction symmetrical with respect to the center line according to the cross angle without coming off from the above of the line center and the plate shape control of the rolling stock corresponding to the rolling conditions is performed easily.

Title: Integrated circuit
Inventor: OBATA TOMOJI
IPC: H01L27/04
Filed: 1981-10-29
Abstract: PURPOSE:To prevent the destruction of a transistor due to an abnormal current when an overcurrent flows to the transistor to be protected, by detecting the voltage drop of a resistance connected to the emitter of said transistor and actuating a protecting circuit. CONSTITUTION:A large current flows to transistors (TR) Q56 and Q58 when an output terminal (n) of an IC-converted power amplifier has a contact with the negative potential of a power supply voltage VCC5. In this case, a TRQ54 works when the voltage drop produced across a resistance R57 exceeds the base-emitter voltage of the TRQ54. As a result, the base driving current of the TRQ56 is absorbed by a collector current to inhibit the working of the TRQ58. This prevents the destruction of the TRQ58 due to an abnormal large current. The resistance R57 is formed with a metallic wiring whose resistance increases as the temperature rises up. As a result, the resistance value of the R57 increases owing to a rising temperature change which is produced when an overcurrent starts to flow to the TRQ58. At the same time, the detecting sensitivity can be improved for the overcurrent.

Title: Non-breed electrode
Inventor: FURANKU SOROMON
IPC: H01M4/88
Filed: 1981-10-30
Abstract: This disclosure is directed to a non-bleeding gas electrode for operation under the rigors of high current density and to the active layer thereof. This active layer is comprised of 60 to 90 weight percent high surface area, electroconductive carbon (with or without catalyst thereon), 10 to 40 weight percent particulate polytetrafluoroethylene (PTFE) and has pores sufficiently large to relieve internal hydrodynamic pressures thus preventing liquid being forced through the electrode wetproofing layer to the air side thereof. In addition such electrodes include a PTFE-containing wetproofing or backing layer secured on one side to said active layer and on the other side to a current distributor. The pores in both the active layer and the backing layer are controlled to relieve hydrodynamic pressures by coordinating the particle size of the pore former used to establish the pores in both said layers such that the repellancy of the backing layer to hot alkali exceeds the internal liquid pressures in the active layer. Of particular significance is the fact that the present electrode is non-bleeding when operated on air and preserves its low voltage at high current density over extended time periods without bleeding.
