Title: Image forming device
Inventor: SUZUKI KAZUO
IPC: G03G15/00
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To make executable surface potential control with high precision in spite of fluctuation of image carriers by controlling the correction values of the potential at the image carrier surface potential detecting measure position and the potential at the development measure position based on the relation of surface potentials calculated to a current or a voltage applied to the image carrier. SOLUTION: A surface potential control of a photosensitive drum 1 is executed by using a surface potential sensor 41 in order to keep the photosensitive drum surface potential at a constant value. Drum potentials corresponding to the two different current reference values applied to the photosensitive drum 1 from a contact charge 2 are measured by the surface potential sensor 41 and a current value capable of obtaining a target potential is calculated by linear approximation at an operation control part 40. Based on the relation of the photosensitive drum surface potential thus calculated by using the surface potential sensor 41 for the current applied to the photosensitive drum 1 from the charger 2, a compensation value of the potential at the surface potential sensor position and the potential at the developer position is controlled.  Consequently a high precision potential control is obtained even for photosensitive bodies having different properties.

Title: Liquid crystal display element
Inventor: WATANABE RYOICHI
IPC: G02F1/1333
Filed: 1988-05-09
Abstract: PURPOSE:To obtain a liquid crystal display element which is free from the variance of lighting display and has three or more gradations by forming two or more kinds of insulating film different in dielectric constant adjacently on a plane on the electrode of at least one substrate. CONSTITUTION:With respect to a liquid crystal display element where liquid crystal is sealed between first and second substrates 5 and 6 on which electrodes 3 and 4 are formed, two or more kinds of insulating film 7 and 8 different in dielectric constant are formed adjacently on a plane at least on one of electrodes 3 and 4 of first and second substrates 5 and 6. That is, when the same voltage is applied to electrodes 3 and 4, the voltage practically applied to liquid crystal 12 is varied because insulating films 7 and 8 interposed between electrodes 3 and 4 and liquid crystal 12 are different in dielectric constant, and as the result, the threshold of liquid crystal 12 determined by voltages applied to electrodes 3 and 4 is varied. Thus, the same gradation display is surely possible in each picture element without especially making ruggedness in the picture element.

Abstract: PURPOSE:To avoid the state where rear wheels are locked in early time by installing an air - liquid converter which boosts up the pressure air supplied from an air pressure source to the pressure liquid and introducing the generated liquid pressure to the liquid chamber of a proportioning valve. CONSTITUTION:The pressurized air supplied from an air pressure source 27 is boosted by an air - liquid converter 21, and converted to the pressure liquid, and introduced into the liquid chamber of a proportioning valve 9. A prescribed pressure is reduced, and the operation of a piston is started with a low liquid pressure, and the subtracted brake torque is generated according to the action of a fluid type retarder 25 on the rear brakes 7 and 34. Accordingly, the brake torque which is generated on the rear brakes 7 and 34 only by a hydraulic brake system in service brake application is lightened according to the brake torque generated by the retarder 25. Accordingly, the brake torque of the retarder 25 is added to the ordinary brake torque accompanied with the service brake application, and the state where rear wheels 8 and 33 are locked in early time is avoided.

Abstract: PURPOSE:To make it possible that a high order station monitors power-off of a commercial power source of a low order station, by transmitting a tone signal from a radiotelephony device of the low order station at intervals of a certain time while the commercial power is supplied. CONSTITUTION:When the commercial power source is turned on, a radio-telephony device 2 of the low order station transmits a tone signal fB to a radiotelephony device 1 if the high order station at intervals of a certain time (a) by a tone signal generating circuit 3.

Title: High speed voltage stepping-up or stepping-down apparatus

Filed: 1995-05-09
Abstract: PURPOSE: To prevent the influences of the inductance and the capacitor of a chopper and to obtain a stable high speed pulse load by forming the structure in which an inverter formed of a transmittance, a diode and a switch with the chopper. CONSTITUTION: An inverter formed of a transmittance T1, a diode D2 and a switch S3 is incorporated in a chopper. The switching of the switch S3 of the inverter is repeated in the state that a switch S2 is opened to form the same state as the state that a load R is connected from the chopper, and the inverter is operated in the state. After the voltage of the capacitor C2 is stabilized, the switch S2 is closed, and the switch S3 is opened to be operated. The high speed pulse load stable at the high speed can be obtained without influence of the time constant of the inductance L and the capacitor C2 of the chopper by these driving operations.

Title: Multiplex communication system
Inventor: ISHIKAWA MASAHIRO
IPC: H04B1/10
Filed: 1990-04-26
Abstract: PURPOSE:To continue the communication even when a fault decreasing a signal level of a transmission message takes place by replacing a reference signal level into a 2nd reference signal level lower than that of the 1st reference signal level when a comparison signal is not normally detected within a prescribed time. CONSTITUTION:When power supply to a transmission station 1(100) is stopped while the multiplex communication system is in operation, a communication bus 400 is connected to ground with a low impedance. Thus, since a signal level of a transmission message is deteriorated and does not exceed a threshold level, an output of a comparator 308 is unchanged. When no change is caused in the output of the comparator 308 even lapse of a prescribed time, a monitor 309 outputs a switching signal to switching elements 306, 307 to replace the threshold level into a 2nd reference signal level V2(312). When the 2nd reference signal level V2(312) is set lower than Vdd/2, the output of the comparator 308 is changed and the communication is continued.

Abstract: PURPOSE:To reduce the size of a copying device on the whole by ejecting a leaflet from a horizontal to an upper position without using any ejection roll, by restricting the leaflet ejected to a catch tray through an upper and a lower sandwiching extrusion member. CONSTITUTION:When the leading edge of a leaflet 9 passed through a transfer part 3 and a fixing roll 8 is detected by a detection switch 10, solenoids 12 and 15 are energized a certain time later to sandwich a leaflet A between upper and lower sandwiching extrusion members 11 and 14 which are driven by the solenoids. Further, the members 11 and 14 curve toward an ejection side to extrude the leaflet A to a catch tray 7. Then, when the solenoid 12 is turned off and the leaflet A falls into the tray 7 by its weight, the solenoid 15 is turned off to eject the leaflet from a horizontal to an upper position without using any ejection roll. This constitution wherein no ejection roll is used decreases in necessary space, thereby reducing the size of a copying device on the whole.
