Title: Thermal drive type overcurrent detector for small-sized dc motor
Inventor: KOBARI KATSUO
IPC: G01R31/34
Filed: 1984-02-20
Abstract: PURPOSE:To detect an overcurrent in response to a speed by adding a heating resistor, to which a current in response to a counterelectromotive force is supplied to automatically decrease the detected current value upon rising of the speed. CONSTITUTION:A current in response to the armature current of a DC motor is supplied to the first heating resistor 5 disposed near a bimetal 1, and a current in response to a counterelectromotive force is supplied to the second heating resistor 7. The first and second resistors 7, 8 are operated in a summing manner. Thus, since an armature current value required to displace the bimetal 1 by the prescribed amount decreases, the detected overcurrent value automatically decreases upon rising of the speed, thereby protecting optimally against the overcurrent in response to the speed.

Title: Capacity detector
Inventor: NAKANISHI KIKUJI
IPC: G01R27/26
Filed: 1983-02-24
Abstract: PURPOSE:To enable accurate detection of a fine change in the capacity by automatically controlling the power source voltage of a detector section to displace the detection point of the change in the capacity each time. CONSTITUTION:A capacitance body to be inspected is connected between a terminal 6 of a crystal oscillator 2 at a detector section 1 and an electrode 3. The oscillation amplitude of the oscillator 2 changes according to a capacity value of a capacitance body and a signal is amplified with an FET5. As a detection voltage value V1 outputted from a waveform shaping section 9 falls below the lower limit voltage value of a lower comparator 12 with an increase in the electric capacity of capacitance body to be inspected, a counter 13 counts up and a voltage control section 14 raises the power source voltage V2 of the detector section 1 so that the detection voltage V1 will be maintained higher than the lower limit voltage value. As the detection voltage value V1 becomes higher than the upper limit voltage value of an upper comparator 11, the power source voltage V2 falls and the detection voltage value V1 is maintained lower than the upper limit voltage value. As the power source voltage V2 is proportional to the electric capacity of the capacitance body to be inspected, a capacity value can be measured. a fine change in the capacity can be detected accurately by reducing the potential range between the upper and lower limits.

Title: Step motor mechanism for electronic watch
Inventor: CHIHARA HIROYUKI
IPC: H02P8/02
Filed: 1980-03-10
Abstract: PURPOSE:To halve the current consumption of step motor, by automatically changing the drive current in response to the load, through the drive current control function given to the step motor mechanism. CONSTITUTION:Constitution is made to play the drive current control function by operating the load detection mechanism and the control circuit. When the input in1 of the NAND gate 11 is H, the drive current flows and the rotor turns. Accompanied with the revolution of the rotor, the detection voltage is induced in the detection coil 6. This voltage is fed to the gate of the inverter 8 via the differentiation circuit. When the rotor turns by a given angle and the voltage of the coil 6 is small, the gate voltage of the inverter 8 is lowered than the threshold voltage with the operation of the differentiation circuit, the inverter 8 is inverted into H. Then, the output of the inverter 10 is inverted into L, then the both outputs of the gate 11 are H to interrupt the drive current. Thus, the time signal starts flowing the drive current and the drive current is interrupted with specified revolution of the rotor, allowing remarkable reduction in the current consumption.

Title: Virtual common memory control system
Inventor: OSHIKIRI HIROSHI
IPC: G06F12/06
Filed: 1989-02-08
Abstract: PURPOSE:To easily add a sub-routine to an area common to the whole logical space by activating the sub-routine stored into a virtual common memory where a driver stored into each individual common memory exclusively possesses a single logical space. CONSTITUTION:The virtual common area is composed as an exclusive logical space M. When an application program calls an exclusive routine 'Driver' in a common memory block, it makes a sub-routine number 'i' into a parameter. The 'Driver' calculates the logical address of the sub-routine by 'i', and stores a logical spatial number (a) at such a time. Thereafter the 'Driver' switches the logical space to the logical space M, and activates a sub-routine #i. Thus only by adding the 'Driver' and the common sub-routine, the sub-routine to the whole logical space common area can be added without the restriction of the limited logical space.

Title: Developing device
Inventor: SATO KOICHIRO
IPC: G03G15/08
Filed: 1995-02-20
Abstract: PURPOSE: To attain excellent development even if the circumferential speed of a developing roller is reduced by providing respective specific developing roller, power sources for developing and electrifying a developer and current limiting means. CONSTITUTION: Toner T carried on the developing roller 11 is made a thin layer by a metallic plate spring blade 13 and charged by the friction. Since a supplying bias is impressed from a power source for supplying 17 to the spring blade 13 as a toner electrifying bias, a charge is directly injected from the spring blade 13 to the toner T and it is sufficiently electrified. At this time, a protective resistance 30 is interposed between the blade 13 and the power source 17 and a current supplied to the blade 13 is limited so that leakage so as to cause irregularities in an image does not occur. Moreover, when the resistance value of the resistance 30 is too high, the current supplied to the blade 13 becomes too low, so that the toner T can not be electrified. Thus, the resistance value of the resistance 30 can be set in consideration of the fact.

Filed: 1985-02-20
Abstract: PURPOSE:To deal with wide-range variance in developer characteristics by applying plural AC voltages of different frequency to a developer carrier which faces a photosensitive body at a specific interval and then varying their application time. CONSTITUTION:Signals of plural frequencies f1 and f2 from an oscillator 19 are superposed upon a DC bias 3 applied to the developer carrier 2 which faces the photosensitive body 1 at the specific interval. Then, f1 and F2, t1 and t2, and t0 are so controlled that t0=t1+t2, where t1 and t2 are duration times of the frequencies f1 and f2 and f0 is the repetition period of f1 and f2. Consequently, the ratio of application times of the plural frequencies within a development time is controlled to control image characteristics, thereby constituting a device which deals with wide-range variance in developer characteristics.

IPC: G03F1/84
Filed: 1978-03-16
Abstract: PURPOSE: To inspect the surface, by moving the semiconductor pellet arranged in a given distance toward X direction, and scanning the optical picture toward Y direction.  
     CONSTITUTION: The pellet image 7 is fed toward X axis by the length p of the photo detection area of the element 11 of the detector 8, and output signal is obtained by making scanning from upper to lower toward Y direction at the position. Since judgement is made while shifting by p, required time can be reduced than conventional methods.

After the element of the detector scanned detects the most external circumference of the pellet, the amount of notch 14 for upper and lower side is judged by counting the number of CP reference determined with the size of pellet and the permissible amount of notch. Further, the pellet shift distance until the number of detection signal corresponding to the normal side is obtained or from the final normal signal to the final side judges the notch 15 at left and right side, and the size of the surface defect 17 is known by counting the continuous delete signal. Thus, physical appearence inspection can easily and quickly be made.
