Abstract: PURPOSE:To prevent discharging to a dielectric belt from a transferring electrifier by installing an insulating part which extends from both side edges of paper to both outer sides of the dielectric belt on the surface of the dielectric belt of the transferring electrifier. CONSTITUTION:The transferring electrifier 5 is formed of a frame 6, wire 7, and a grid 8, each formed from stainless steel. Further, the insulating part (holder lid) 14 which extends from both side edges of the paper 4 and both outer sides of the dielectric belt 1 is installed on the surface on the dielectric belt 1 side of the transferring electrifier 5. Then a multiple number of tongues 15 are formed on this holder lid 14, and these tongues 15 are repulsively engaged to an engagement part 16 formed on wire holders 9 and 10. Therefore, even when both side edges of the dielectric belt 1 is warped in the direction of the outer periphery, it comes into the vicinity of or comes into contact with the holder grid 14. Thus discharging from the transferring electrifier 5 to the dielectric belt 1 can be prevented.

Title: Magnetic sensor and manufacture thereof
Inventor: KUBO SHOICHI
IPC: G01D5/245
Filed: 1989-05-19
Abstract: PURPOSE:To detect a magnetic field by a ferromagnetic Hall effect device and to obtain a sine wave by generating a magnetic field in the same direction as an axis of a cylindrical drum in an outer periphery thereof, and moving a magnetic track in a sine curve in the axial direction simultaneously when said drum is rotated. CONSTITUTION:When a position x1 of a magnetic track 2c is opposed to detecting portions R1A,R2A, the resistance value of the detecting portion R2A is changed most to be negative, with an output voltage VA becoming the maximum value. When a position x2 of the magnetic track 2c confronts to the detecting portions, a magnetic field is applied to the detecting portions R1A,R2A in the same manner, so that the resistance value is changed the same, with the output voltage becoming half of a source voltage. Further, when a position x3 of the magnetic track 2c confronts to the detecting portions, the resistance value of the detecting portion R1A is changed most to be negative, with the output voltage VA turned to be minimum. Similarly, when the magnetic track 2c confronts to the detecting portions at positions x4,x5, the output VA is changed. Since the magnetic track is in a sine curve except at positions x1-x6, the generating magnetic field draws the sine curve and the output voltage VA changes in the sine curve. As the magnetic drum 1 makes one rotation, the output voltage VA of sine wave of 1 Hz is obtained. The phase of a magnetic track 2d leads 90 degrees with respect to that of a track 2a when the drum 1 is rotated in a direction shown by an arrow.
