Title: Transfer device for image forming device
Inventor: YUNAMOCHI TAKAYASU
IPC: G03G15/16
Filed: 1993-08-03
Abstract: PURPOSE:To prevent a failure in the transfer of a part corresponding to the gap between respective conductive elastic layers, the staining of the rear side of a transfer material caused by a paper track after a small-sized transfer material passes, etc., when the conductive elastic layer of a transfer roller is a divided one. CONSTITUTION:The electrodes 6 and 8 of three divisions are fitted into an insulated core metal 9 and the outer peripheries of these electrodes are surrounded by the conductive elastic layers 18, to constitute the transfer roller 19. The conductive layers 18 have 10<7>-10<10>OMEGAcm middle resistance and are abutted on a photosensitive drum 1 to form a transfer nipping part. In the transfer material of a narrow passing range, a transfer bias is applied on only the electrode 8 via a switch 11 and in the transfer material 17 of a wide passing range, the transfer bias is applied on the electrodes 6 and 8 via the switches 10 and 11. The elastic layers are integrated so that the failure ire the transfer is not generated. Moreover, an unwanted transfer bias is never applied on a nonpaper passing part.

Title: Perforation forming cutter
Inventor: YAMAGAMI NORIO
IPC: B31B1/90
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To reliably open a package along perforations by reliably and sufficiently forming a notch on the front/rear ends of the perforations, by making an inclination of the taper surface different between the cutter body side and the cutting edge side, and forming a cutting edge side inclination larger than a cutter body side inclination. SOLUTION: An inclination α of the taper surface 13 continuing with a cutting edge 14 formed as symmetrical both side surfaces of a cutting edge 11, is formed so as to become larger than an inclination β of the cutting edge base part 12 side taper surface 17 formed on the cutter body side of the edge 11. It is better to properly select the inclination α by a blade width and an interval of the cutting edge 14, material and thickness of a workpiece and a diemsion of the cutting edge 14 and a groove inside cutting edge 15. It is better to set the inclination α of the cutting edge 14 side taper surface 13 to about 40 degrees to form perforations at the normal temperature by such an edge 11.  When the inclination αis smaller than this, a sufficient notch is not formed on the front/rear ends of the perforations, and to the contrary, when the inclination α is large, an edge angle of the cutting edge 14 becomes an obtuse angle, so that the perforations are hardly formed.

Title: Negative feedback amplifier
Inventor: NAGATA YOSHIAKI
IPC: H04L27/01
Filed: 1986-09-10
Abstract: PURPOSE:To prevent an output signal spectrum from deterioration due to the delay of a power amplifier or the like by adding a control circuit for outputting a control signal indicating whether the average value of outputs obtained from the power amplifier is >= or <=a fixed value in case of demodulating the output of the power amplifier and feeding back the demodulated signal as a base band signal and a variable gain circuit for adjusting negative feedback gain at the time of receiving the output of the control circuit so that average power inputted to the control circuit is always fixed. CONSTITUTION:The 1st and 2nd base band signals are inputted to a DC/AC converter 130 through subtractors 110, 115 and LPFs 120, 125. A signal modulated by the converter 130 is amplified by a power amplifier 140. A part of the output of the amplifier 140 is attenuated by a variable gain attenuator 145 and inputted to a DC/AC demodulator 135. The demodulator 135 receives the output of the attenuator 145 and the output of a sine wave generator 131 through a phase shifter 132 and demodulates the inputted signals to obtained a base band signal. The input to the attenuator 145 is also inputted to a control circuit 150 and a gain control signal is obtained from the attenuator 145 so that a required value is obtained from said input. The output of the control circuit 150 controls the attenuator 145 so that the attenuation of the attenuator 145 is reduced when the output of the amplifier 140 exceeds a required value, and when the output is smaller than the required value, the attenuation is increased. Consequently, a negative feedback circuit can be prevented from the deterioration of the whole characteristics due to the change of delay characteristics from a designed value.

Title: Controller for current-type inverter
Inventor: MITSUNE SHUNSUKE
IPC: H02M7/12
Filed: 1988-08-27
Abstract: PURPOSE:To smooth the operation of an inverter by suppressing the generation of overvoltage low through providing a rate of change limiting means fixing the rate of change of an output current command value to a specified value. CONSTITUTION:A current command value I* is inputted to a converter side and controlled by an ACR circuit 17 so that DC current becomes Ia. A frequency command value omega* and a control phase command value theta* are inputted to an inverter side so that an integrated-phase command value thetaT* is generated by an integrated-phase command phase arithmetic circuit 18. When said integrated-phase command value thetaT* changes suddenly, an output current i1 changes sharply. In this case, it is judged by the equation I in said integrated- phase command arithmetic circuit 18 whether the rate of change of said control phase command value theta* exceeds a specified value  theta. When said equation I is satisfied, said output current i1 can suppress the rate of change di1/dt to a small value, even if said integrated-phase command value thetaT* changes suddenly. Therefore, an overvoltage can be reduced substantially.
