Abstract: PROBLEM TO BE SOLVED: To precisely control toner replenishment, to form a proper-density image and to prevent an undesirable phenomenon such as toner splash by finding the stop time and the operation time of a developing device and correcting the control of a toner replenishment device by a control means, based on the stop time and the operation time. SOLUTION: The standstill state of a developer, that means, time in the stop state of a developing unit 20 is calculated by considering the characteristic of an L sensor 40. Based on the calculated time in a stop state of the unit 20, the operation relation of a toner replenishment means with respect to the output of the sensor 40 is corrected. Then, when image forming is started and the unit 20 is operated, the stop state of the unit 20 is interrupted, that means, the progress of the stop time is stopped. Since the developer is stirred by this action, there is the function that the stop time is shortened. Then, the operation of the unit 20 is detected and the stop time and the characteristic recovery time of the unit 20 are calculated from the detected result by a control part.  Then, the control part performs the correction based on the stop time and the characteristic recovery time of the unit 20.

Abstract: PROBLEM TO BE SOLVED: To improve the operating efficiency by providing a determining means for determining the generation of foam in the fuel to be injected in an Atkinson' s cycle engine, and operating a foam generation restricting means so as to prevent the generation of foam when the generation of foam is detected. SOLUTION: In an Atkinson's cycle engine, of which compression starting time is delayed by shifting the closing timing of an intake valve 2 to a delay angle side so that a part of the air sucked into a cylinder 1 once is pushed back to the inside of an intake port 8, since the expansion volume becomes larger than the intake air volume, expansion energy by combustion can be recovered more as the kinetic energy, and energy efficiency of the engine can be improved. At this stage, an ECU 18 determines the fuel temperature and the existence of foam on the basis of the signal from an intake port sensor 9 and a fuel temperature sensor 16 or the like. In the case where the generation of foam is determined, fuel pressure is raised by a fuel pressure adjusting valve 14 so as to prevent the generation of foam in the fuel to be injected.

Title: Gyrocompass
Inventor: HOJO TAKESHI
IPC: G01C19/18
Filed: 1987-10-02
Abstract: PURPOSE:To omit a torquer coil and to make the constitution compact, in a gyrocompass using a flex gyroscope, by feeding back the output of a displacement pickup inn axial direction to a forcer coil through a compensation amplifier, which undergoes required feedback control. CONSTITUTION:The displacement of a gyro rotor 7 in the axial direction is detected with a Z-pickup 22 and fed back to a forcer coil 16 in the direction Z. Thus an accelerometer loop 110 is formed. Meanwhile, the output of an amplifier 101 is proportional to the slant angle of a gyro spin axis with respect to a horizontal plane. Therefore, north directing torque and damping torque are operated in an operating device 100 from said fact of proportion. Then the torques are fed back to the input side of a compensation amplifier 101 through a sample/hold device 105. Thus the gyro rotor is offset in the axial direction. Then, the north directing and damping torques are formed by the dead weight of the gyro rotor. In this constitution, it is not necessary to provide a torquer coil in addition to the forcer coil, which makes the axial direction displacement of the gyro rotor to be zero. The constitution of the gyrocompass is made compact.
