Title: Automatic off-set compensating circuit for switched capacitor filter
Inventor: KIDO MITSUYASU
IPC: G06G7/12
Filed: 1985-02-27
Abstract: PURPOSE:To prevent the receiving of the influence for the initial value deviation and change and to decrease the off-set voltage by being provided with a low- pass filter (off-set voltage detecting circuit) and an adder circuit whose cut-off frequency is sufficiently lower than the signal component, and synthesizing the extracted off-set voltage and the output of the filter facing forwards or facing backwards. CONSTITUTION:When a sine wave voltage Vi is inputted into a switched capacitor filter 1, a step waveform Ve1 including the off-set of an operational amplifier and an off-set voltage Ve1 by a switching noise, etc., is outputted. By inputting the output voltage Ve1 and the output voltage Vof of an off-set voltage detecting circuit 3 with a gain as 1 into the adder circuit, a step waveform Ve2 whose off-set voltage is reduced by half and goes to be Ve2 is outputted. A time constant and a gain of an off-set voltage detecting circuit 3 is obtained sufficiently largely, thereby an automatic off-set compensation of a switched capacitor filter 1 can be executed.

Filed: 1985-02-28
Abstract: PURPOSE:To easily perform color changing operation by storing developers or toner particles of different colors in a developer changeover container and a developer storage chamber separately and providing a supply chamber and the developer storage chamber with a supply means which supplies a developer to a developing roller individually. CONSTITUTION:When colors of development are changed, a shutter 17 is moved to isolate the scooping-up roller 15 and developing roller 16 in the developer storage chamber 3 from each other or to stop the scooping-up roller 15 and stop supplying a developer from the scooping-up roller 15 to the developing roller 16. In this state, when the developing roller 16 and a photosensitive body are rotated continuously, toner that the developing roller 16 carries is recovered in a toner recovering device through the photosensitive body 1. When the recovery of almost all toner from the developing roller 16 is detected, the developer changeover container 11 is rotated and the supply roller 14 of a chamber 13 which contains toner of specified color is stopped and held where the toner is supplied to the developing roller 16. Consequently, the toner supplied from the developer changeover container 11 is used to visualize a latent image on the photosensitive body 1, thus obtaining an image of the desired color.

Title: Device for inspecting edge of elastic body
Inventor: HACHIMAN TOSHIYUKI
IPC: G01M13/00
Filed: 1988-02-20
Abstract: PURPOSE:To inspect the edge of an elastic body by bringing a cat whisker into contact with the edge of the elastic body under a fixed pressure and converting the fluctuation of the contact pressure when the elastic body moves into voltage signals, and then, comparing the voltage signals with a reference value so as to obtain binarization signals. CONSTITUTION:After a blade B is placed on a table 1 and a cat whisker 4 is put on an edge C, with a pressure of 1-2g being applied to the edge of the cat whisker 4, the blade B is moved by means of a feeding screw mechanism 2 at a speed of 100-200mm/sec. The edge of the cat whisker 4 has a width of 0.2-1mm, nose angle of 60-90 deg., and arc radius of 5-8mu. Fluctuation of the contact pressure of the cat whisker 4 caused by the unevenness of the edge C is converted into voltage signals by means of a piezoelectric acceleration detector 5 and the voltage signals are compared with a reference value by means of a binarization converter 12 after the signals are passed through an amplifier 11. When the voltage signals exceed the reference value, '1' is outputted and the '1' is sent to a signal processor 14. Since the position signal of a position detector 13 which detects the position of the edge C of the blade B is sent to the processor 14, a defective point is indicated on a display device 16 for confirmation. The defective point is stored in a storage device 15 and can be confirmed by a microscope after inspection.

CONSTITUTION:The equalizer is provided with a second-order circulation filter in cascade connection to a non-circulation filter and an adder 17 adding the output of the circulation filter and the output of the non-circulation filter to provide the sum as an inter-code interference. In the second-order circulation filter, a 1st feedback coefficient is the sum of a 1st attenuation coefficient being a fixed value and a variable 2nd attenuation coefficient subject to adaptive control, a 2nd feedback coefficient is a product between the 1st attenuation coefficient and the 2nd attenuation coefficient whose sign is inverted to provide an output being a sum of an output of a circuit multiplying a weight of a 1st tap with a 1st tap output and an output of a circuit multiplying a weight of a 2nd tap with a 2nd tap output and uses a control signal of the 2nd attenuation coefficient, which is obtained by subtracting a product between the 1st attenuation coefficient and a 3rd tap output resulting from a 3rd tap output delaying a 2nd tap output by a one-symbol time from the 2nd tap output and by multiplying the weight of the 1st tap and an error signal resulting from the discrimination with the difference above.
