Title: Bias stabilizing circuit
Inventor: SUGAWARA MITSUTOSHI
IPC: H03F1/30
Filed: 1981-09-07
Abstract: PURPOSE: To compensate the influence of a bias variation due to a resistance connected to the base of a pair of transistors, in case when supply voltage is low, etc., by equalizing the bias voltage of the first and second transistors constituting a differential pair, with reference voltage.  
     CONSTITUTION: When base bias voltage of transistors 1, 2 rises, the impedance of a variable impedance device of a voltage controlling circuit 8 is increased by error voltage from a voltage comparator 6. As a result, voltage between an electric power source 9 and a terminal 10 is greatly dropped, voltage of the terminal is reduced, and base voltage of the transistor 1 or 2 is dropped. On the other hand, in case when the base vias voltage of the transistors 1, 2 has dropped, said operation is reversed. In this way, a negative feedback type automatic control is operated so that base voltage of the transistors 1, 2 is equalized with voltage of a reference electric power source 7. Since the base bias voltage of the transistors 1, 2 can be equalized with supply voltage, the bias of the transistors 1, 2 becomes constant irrespective of a voltage drop generated by high resistances 4, 5.

Filed: 1984-07-09
Abstract: PURPOSE:To take high-precision measurement by constituting a microwave bridge in a microwave transmitting circuit and reducing a standing wave error. CONSTITUTION:A material 15 for measurement is put in a slit 14 for measurement and a radio microwave from a microwave oscillator 1 is divided into a wave propagating as shown by an arrow 18 and a wave propagating as shown by an arrow 20. The radio wave in the direction of the arrow 18 is attenuated by water in the material 15, reflected by a plunger 17, and led to a detector 9 as shown by a dotted-line arrow 19. The wave in the direction of the arrow 20, on the other hand, is passed through a variable attenuator 6 and reflected by a plunger 8 to reach a detector 9 as shown by a dotted-line arrow 21. Therefore, when signals of both arms are equal in attenuation quantity and 180 deg. out of phase with each other, an output signal is zero and an indicator 11 indicates zero. For the purpose, both arms are balanced before measuring operation and the amount of water is measured from the deflection of the meter when the radio wave is passed through the material 15. Further, the standing wave error due to the reflection of the plunger is small, so the precision of the measurement is high.

Filed: 1978-11-17
Abstract: PURPOSE:To let a laminated type photoreceptor maintain always good chargeability and photosensitivity during continuous copying operation by radiating the photoreceptor by the use of the light removed of the light of the wavelength absorbed in the carrier moving layer on a conductor substrate thereby destaticizing the same. CONSTITUTION:Light of the wavelength absorbed to a carrier moving layer 13 is removed with a filter such as of methyl anthrathene or the like. The filter is mounted to a quenching lamp 9. A photoreceptor 1 comprises subsequently laminating a carrier generating layer 12, carrier moving layer 13 on a conductive substrate 11. The cause for light fatigue which degrades the charging characteristics and photosensitivity characteristics of the photoreceptor lies in that the light applied from the quenching lamp 9 is absorbed in the carrier moving layer 13. Hence, by mounting the filter to the qenching lamp 9 and removing absorption wavelength bands, the light fatigue of the photoreceptor may be prevented and good chargeability and photosensitivity may be maintained.
