Title: Rotor for super-conduction rotary electric machine
Inventor: TAKANO ICHIROU
IPC: H02K55/04
Filed: 1978-11-28
Abstract: PURPOSE: To reduce the rising voltage produced at the time of quenching and thereby eliminate fluctuation in electromagnetic force by dividing two bipolar coils and connecting in series in loop the divided coils of the two coils which are in the symmetrical positions.  
     CONSTITUTION: Bipolar super-conducting coils 1 and 2 are divided into three coils, 5∼7, and 8∼10 respectively, and are fitted to rotor 4. Divided coils of both bipolar coils that are in the symmetrical positions, namely, 5 and 8, 6 and 9, and 7 and 10 are closed by connecting them in series. By this, the voltage produced when quenching occurred is reduced to 1/3 compared with the case when the coils are not divided, and also no deviation in electromagnetic force occures, and thereby it is possible to prevent damage to the rotor due to quenching.

Abstract: PURPOSE: To prevent the deterioration of image quality by forming clearance for allowing a copy sheet to pass to a transfer area with a pretransfer baffle and a charge holding material, and bringing the copy sheet into contact with the charge holding member before the copy sheet reaches the transfer area. CONSTITUTION: A pretransfer baffle 52 made of a suitable metal or conductive material biased to, for example, 1500 volt(DC) is arranged close to a corotron 50 for transfer. The baffle 52 neutralizes the effect of -1500 volt(DC) of a charge holding member on a copy sheet 70 before the copy sheet 70 reaches the corotron 50 for transfer. When the copy sheet 70 passes through the pretransfer baffle 52, the copy sheet 70 is brought into contact with the baffle, a negative bias is applied to the copy sheet 70 by the baffle 52, and an undesired magnetic filed for transfer between the charge holding member 42 and the copy sheet 70 is weakened, and the geometrical array and position of the copy sheet 70 for the charge holding member 42 is controlled. Thus, the deterioration of image quality on the copy sheet can be prevented.

Abstract: PURPOSE:To stably polish a tape sliding face for a long time by rotatably fixing a blacket for rotatably supporting tape path adjusting roller for guiding a lapping tape to a supporting member. CONSTITUTION:Clockwise force is applied to a roller 21 by tape tension. Since force applied to a Y part to be the lower end side of a tape is larger than force applied to an X part to be the upper end side of the tape, counterclockwise moment around the rotational center 24a of a blacket 23 is applied to the roller 21. Thereby, the blacket 23 is rotated in the counterclockwise direction by the moment together with the roller 21 and the width direction tension of the lapping tape 104 is automatically stabilized by the rotational direction of the roller 21. Thus, the tape sliding face can be highly accurately polished.
