IPC: H01R33/06
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To provide an electric connector which easily fixes and replaces an electric terminal, and enables safe and certain electric connection. SOLUTION: An electric connector consists of a connector housing 2 which consists of insulating members, and a conductive electric terminal 3 which is built in this connector housing.

Title: Developing device
Inventor: SAKAMOTO KOJI
IPC: G03G15/06
Filed: 1989-03-03
Abstract: PURPOSE:To control the bias voltage of a developing roller so that the proper surface potential of the developing roller is obtained in a development area even when the developing roller has a resistance body by providing a correcting means which corrects a deviation in the time until a toner layer whose surface potential is measured reaches the development area from its measurement position. CONSTITUTION:A surface electrometer 10 measures the surface potential of the developing roller 4 which includes the toner layer and inputs the measured surface potential to a difference detecting circuit 12. A bias voltage which is applied to a conductive base 7 is inputted to the detecting circuit 12, which outputs the difference between the bias voltage and actually measured value. This output is outputted after being delayed by a delay circuit 13 by the time (t) required for the developing roller to move from the potential measurement position to the development area A. Then this output is subtracted by a 2nd difference detecting circuit 14 from the reference bias voltage value V0 of a power source 15 and the resulting bias voltage is applied to the conductor of the developing roller 4, i.e. base 7. Consequently, even when the developing roller having the resistance body is used, the surface potential of the developing roller 4 in the development area A can be controlled to a constant value.

Title: Frictional damper provided with speed-up mechanism
Inventor: HIKITA KENJI
IPC: F16F7/10
Filed: 1982-03-31
Abstract: PURPOSE:To obtain the damping effect of a large capacity with no increase in the mass of a flywheel, by increasing the rotational speed of a screw rod with the use of a differential gear speed-up mechanism and then transmitting the rotation of the screw rod to the flywheel. CONSTITUTION:A recirculating ball member 4 is rotated by a screw rod 3 when a relative displacement between a main casing 1 and a subcasting 2 comes about. The rotation of the recirculating ball member 4 is transmitted to a flywheel 7 through a differential speed-up mechanism comprising gears 5, 6, 7a. The rotation of the flywheel 7 is transmitted to a friction member 9 through balls 11 when an acceleration in the rotation of the recirculating ball member 4 is low, and therefore, the friction member 9 is driven to rotate with a predetermined gap being defined between a lid 1c and the friction member 9. Further, a relative displacement between the flywheel and the friction member 9 comes about due to the inertia force of the friction member 9 when an acceleration in the rotation of the recirculating ball member 4 is high, and therefore the balls 11 roll up on a slant surface so that the friction member 9 is frictionally engaged with the lid 1c, thereby the effect of damping may be obtained.
