Filed: 1989-05-19
Abstract: PURPOSE:To secure the time necessary for write protecting process against the sudden voltage drop of a power supply by dropping, rectifying three-phase AC power supply voltage and comparing the same with reference voltage. CONSTITUTION:U-, V- and W-phase are rectified by a three-phase rectifier SB1 and rectified voltage ES1 of two phases U, W among the phases U, V, W is inputted to a control DC power supply PS. This power supply PS has a microprocessor MPU and a memory MEM 1 built therein and becomes the power supply for operating a control circuit CPU 1 controlling an external input/output apparatus. In a voltage drop detecting circuit CP1, the voltage ES1 is ripple filtered by a capacitor C1 and divided by registors R1, R2 to obtain comparing voltage EC1 which is, in turn, set to one input voltage of a comparing circuit CMP to be compared with the other reference voltage E1 of said circuit CMP. By this method, since a change of three-phase power supply voltage is detected by a ripple filter circuit with a small time constant, the abnormality thereof is detected at an early stage and light protecting processing can be performed a surplus time.

Title: Timing signal generator
Inventor: TAWARA SHUICHI
IPC: H03K5/15
Filed: 1988-05-25
Abstract: PURPOSE:To generate an arbitrary and same size timing, to execute miniaturization and to execute the high integration by controlling the critical current value and input signal of Josephson junction. CONSTITUTION:Since input resistances 110 and 111 are set to the same value, and an input signal 8 impressed to an input signal line 3 is equally branched and inputted to Josephson junctions 1 and 2 having a different critical current value. At times t1 and t2 when the input signal 8 exceeds current values I1 and I2, the Josephson junctions 1 and 2 are respectively switched. Times t2-t1 are equivalent to a delaying time (t). After the Josephson junctions 1 and 2 are switched, an output side becomes a high load and the current flows through output resistances 104 and 105 to a ground. Consequently, current pulses 9 and 10 of the equal size are obtained from output lines 4 and 5. Compared with the case when the delaying line is used, miniaturization and high integration can be executed.

Title: Controller for cleaning system
Inventor: AOYAMA HAJIME
IPC: A47L9/00
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To obtain a controller for a cleaning system which shortens a stoppage distance while avoiding any malfunctions, at the time of an emergency stoppage. SOLUTION: It relates to a controller 10 which controls each function by the main controller 12 mounted on a cleaning system 1 performing a cleaning operation by a cleaning means to pivot and drive left and right drive wheels 30 by means of a drive motor 32. When an emergency stoppage switch 50 is pushed down, current feeding to the drive motor 32 is shut off by means of a delay signal which delays for a predetermined period of time generated from a delay part 60 after the control operation of the drive motor 32. In this instance, a stoppage means which shuts off current feeding to the drive motor 32 to prevent the drive motor driver 34 not only from malfunctions but also from running.  Thereby, even when the drive motor driver 34 and motor driver 58 are not functioning properly, current feeding to each motor is shut off after a predetermined period of time (e.g. 0.3 seconds) elapses, and the cleaning system 1 reduces in speed and stops from running, by force of inertia.

Abstract: PURPOSE:To supply a toner without scattering the toner around a device neither dirtying the worker by breaking a seal of a toner supply box with a projecting part provided in a storage part and supplying the toner in the state where the supply box is inserted into a storage vessel. CONSTITUTION:When an upper cover of a toner supply box 1 is removed to insert the toner supply box 1 to an upper supply hole 7 of a storage vessel 6, a projection 5 directed to the central part of the supply hole 7 breaks the seal face of the supply box 1. When the supply box 1 is lifted slightly, the toner is dropped from an aperture part opened in the seal face and is stored in the storage vessel 6. Consequently, the toner is supplied easily only by attaching and detaching the supply box 1 to and from the supply hole 7, and the supply work is performed without scattering the toner around the device neither dirtying the device and the worker.
