Patent JP-H07304117-A (JP)
Title: Charge roll and production thereof
Inventor: SHIRAKI KEITA
IPC: B05C1/02
Filed: 1994-05-10
Abstract: PURPOSE:To reduce the electric etching action on a photosensitive drum and the shaving quantity of a sensitive material by forming a protective layer on a roll main body so that the protective layer is made thinnest at the axial central part of the roll main body and becomes gradually thick toward both end parts thereof to form the whole of a roll into a hand drum-shape. CONSTITUTION:A charge roll is constituted so that a conductive elastic material layer 2 is formed on the outer peripheral surface of a core body 1 and a semiconductor resistance adjusting layer 3 is formed on the outer peripheral surface thereof and a protective layer 4 is further formed on the outer peripheral surface thereof so as to be made thinnest at the axial central part of the roll and to become gradually thick toward both end parts thereof and formed into a hand drum-shape as a whole. By this constitution, since the resistance of both end parts of the charge roll is higher than that of the central part thereof when the charge roll is used in contact with a photosensitive drum, AC voltage is reduced and a current value becomes low and the shaving quantity of a sensitive material at both end parts of the roll is reduced. Since a change of a resistance value is provided in the axial direction of the protective layer 4 by the film thickness difference of the same material, the central part and both end parts of the charge roll have the same environmental dependence.

Filed: 1988-04-20
Abstract: PURPOSE:To suitably subject a video signal to signal processing by leading out a field discrimination signal from a composite video signal and multiplying a horizontal synchronizing signal as prescribed by a voltage controlled oscillator VCO to generate a clock signal. CONSTITUTION:The horizontal synchronizing signal is multiplied as prescribed only by a VCO 28 to generate a sampling clock signal, and pulses having a narrow pulse width of a noise component are eliminated from a composite synchronizing signal by a field detecting circuit, and thereafter, the number of change pulses is counted to detect the field discrimination signal. Thus, the sampling clock signal is generated with a very low cost, and the accurate field discrimination signal of very high reliability is led out because the probability of the malfunction of the circuit is reduced as much as possible. Consequently, various video signal processings such as the use of the field discrimination signal and the sampling clock signal as the address signal of a frame memory or the like are suitably executed.
