摘要： An exposure control device for a camera having a shutter mechanism, a solenoid serving as an electromagnetic drive, a presser for pressing a solenoid plunger, and a control circuit for conduction control for the solenoid. After the solenoid attracts the plunger to open the shutter, conduction voltage for holding the plunger is controlled within a permissible range and become lower than the conduction voltage utilized for initially attracting the plunger. The heating of the solenoid is thus minimized. This control sequence prevents the breakdown of the solenoid and improved reliability in exposure control. Furthermore, power consumption in the camera is minimized.

摘要： A machine part used as a magnet roll for developing and a process for producing the same. The machine part constitutes a member of a developing machine for an electrophotographic process such as a copier and facsimile, and a laser printer as well. The machine part comprises a shaft having a resin-bonded magnet layer provided on the outer periphery thereof. The composite molding of a resin-bonded magnet is produced by molding and establishing a composition for a thermoplastic resin-bonded magnet comprising from 35 to 60 % by volume of a thermoplastic resin and from 40 to 65 % by volume of a hard ferrite powder into a cylinder of uniform thickness on the outer periphery of a shaft, obtained is a thin resin-bonded magnet layer having a surface roughness of 5 .mu.m or less and free of seams which have generated during molding, the thin resin-bonded magnet layer further having provided on the surface a plurality of magnetic poles at a small spacing.
