Title: Tester for semiconductor device
Inventor: YAMAGUCHI TAKASHI
IPC: G01R31/02
Filed: 1979-08-15
Abstract: PURPOSE: To stably measure an input offset voltage, by changing an applied voltage at every time when the output of a measured object DUT crosses a reference voltage and by measuring the applied voltage when the change in the voltage has converged.  
     CONSTITUTION: A voltage VE is applied from a continual comparison voltage generation circuit 20 to the inverted input terminal of a DUT1 by clock pulses from a clock signal generation circuit 12. When a switch 13 is opened, the output voltage +VO of the DUT1 is compared with a reference voltage VR by a voltage comparison circuit 16. If the voltage VO is higher than the reference voltage VR, a weight of such bits is applied to a comparision register 21 that the output voltage of the circuit 20 becomes equal to 1/2VE. Such operation is repeated to the final bit (n). The output voltage of the continual comparison voltage generation circuit 20 corresponding to a weight of bits of the comparison register at the final bit (n) is measured by a voltage measurement circuit 17 to determine an input offset voltage. According to this constitution, positive feedback is effected so that stable discrimination can be performed even if the DUT1 is likely to oscillate.

Title: Dynamic frequency dividing circuit
Inventor: MATSUURA YOSHIAKI
IPC: G04D7/00
Filed: 1981-07-02
Abstract: PURPOSE:To fix an initial state unequivocally and to make it steady by forcibly fixing output terminals of plural MOSFET arrays of a dynamic frequency dividing circuit at an input or power voltage level by an input signal and a control signal. CONSTITUTION:When an input terminal 15 and a control terminal 2 are held at a level VSS, an FET58 turns on and an FET61 turns off to forcibly hold a terminal 6 at a level VDD. An output terminal 16 is held forcibly at the level VSS because an FET64 is on and an FET62 is off. As a result, an FET52 turns on and an FET53 also turns on because the terminal 15 is at the level VSS. On the other hand, FETs 54 and 55 are off, so a terminal 3 is also held forcibly at the level VDD. Therefore, a stationary state is fixed unequivocally and any floating state does not occur. No influence of noises is exerted and operation at a specific frequency is eliminated without reference to the stopping of input.

Title: Rotary type brush roll
Inventor: KAWAMURA KIICHI
IPC: A46B7/10
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To realize uniform electrification by spirally winding a ribbon-like brush body where conductive brush bristles are pile-woven in a base member round a core bar roller. SOLUTION: The brush roll 10 is obtained by spirally winding the ribbon-like brush body round the core bar roll 12. The brush body is obtained by pile- weaving a conductive fiber 18 in a foundation 16. Since the pile-weaving direction is set to a direction orthogonal to the longitudinal direction of the brush body, that is, nearly parallel with the direction of the rotary shaft of the roll 10, a stripe-pattern spot is not made even in the case of electrification by the roll 10. By making the pile-weaving direction nearly parallel with the direction of the rotary shaft of the roll 10, the electrification is performed along in the direction of the rotary shaft of a photoreceptor drum by the brush bristle 17 formed of one conductive fiber 18, so that the electrification spot is not made along in the direction of the rotary shaft of the photoreceptor drum. Since electrification is performed by the brush bristle 17 along in the lateral direction of paper, the stripe pattern does not appear in the case of printing the paper in the longitudinal direction.

Title: Detector for force-fed amount of force-fed fine powder
Inventor: FUKUICHI KIYOSHI
IPC: E21D11/10
Filed: 1991-05-09
Abstract: PURPOSE:To allow highly accurate detection in real time by providing a vane for detecting a flow rate and stirring powder and a rotation body having a groove for holding the powder. CONSTITUTION:A vane 4 for detecting a flow rate and stirring powder provided on a powder force feeding pipe 1 is rotated by energy of compressed gas flowing at a high speed, whereby a speed detecting motor 12 is driven to have generated current varied. The powder flowing in layers in the force feeding pipe 1 is stirred and scattered and goes toward a cone rotating body 6 of a cone part 2 in a separation state. The rotating body 6 is applied with force by a compressed coil spring 10 and rotates while pressing the powder against an inner wall of the cone part 2. Therefore a rotation torque of the rotating body 6 changes with friction due to an amount of the powder held between the rotating body 6 and the cone part 2 and its nature, thereby changing current of a torque detecting motor 11. A calculator 13 obtains a flow rate from the changing current of the motor 12, obtains an amount of the powder from the changing current of the motor 11, and highly accurately calculates a flow rate of the force-fed powder in real time.
