US Patent:

41282990, Dec 5, 1978

Filed:

May 12, 1977

Appl. No.:

5/796262

Inventors:

James Maher - Sodus NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G02B 514
G02F 129

US Classification:

350 9613

Abstract:

Light propagating in a waveguide is modulated by deforming a cladding on at least one surface of the waveguide. The cladding has a thickness at least equal to the exponential depth of the evanescant field of the propagating light. A pair of electrode means is used to impress a field across the waveguide and cladding so that the cladding is deformed to a degree sufficient to interfere with the evanescant field and to modulate the propagating light.

Susan Pike Farnand - Fairport NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03G 2100

US Classification:

399 98

Abstract:

A development station for an electrostatographic reproduction apparatus wherein pigmented marking particles from a particulate material mixture of pigmented marking particles and magnetic carrier particles are utilized to develop latent image charge patterns on a dielectric member. The development station has a housing adapted to be located adjacent to a dielectric member. The housing defines a reservoir for a particulate material mixture, and an opening facing such dielectric member. A mixer for mixing particulate material, a magnetic brush for applying pigmented marking particles from such particulate material mixture to a latent image charge pattern to develop such charge pattern, and a transport for transporting such particulate material from the mixer to the magnetic brush are located within the housing. A device is provided for collecting contaminating airborne particulate material contamination. The contamination collecting device includes an elongated tube, located externally of the housing.

Appl. No.:

5/710484

Inventors:

Gustav R. Pfister - Webster NY
James C. Maher - Sodus NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

H03F 304

US Classification:

330 5

Abstract:

Amplification of optical signals propagating through a first waveguide is achieved by modulation of high intensity light propagating through an elastomeric waveguide responsive to said signals, the modulation of the high intensity light being accomplished by an apparatus including a photodiode for registering the modulation of the optical signals and an electrode arrangement for causing corresponding light-modulating deformation of the elastomeric waveguide, the circuitry between photodiode and the electrode arrangement including a resistor and a D. C. power source.

Appl. No.:

8/199903

Inventors:

Edward T. Miskinis - Rochester NY
Richard A. Weitzel - Hilton NY
James C. Maher - North Rose NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03G 2100

US Classification:

355208

Abstract:

A toner monitor which measures the magnetic permeability of the developer mix uses a coil around the toner monitor so that when energized with a DC current, the coil acts as an electromagnet to align the developer mix in a consistent fashion at the monitor. The permeability of the mix is measured and the DC current to the coil is inhibited allows the measured sample to fall away or be moved away from the sensor by mixing augers or paddles. When current to the coil is once again restored, another sample is captured and aligned with the monitor. Information concerning the permeability of the developer mix is used to control replenishment of the toner.

James C. Maher - North Rose NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03G 2100

US Classification:

399353

Abstract:

An electrostatographic imaging apparatus and method for cleaning remnant toner. An intermediate transfer member (ITM) is in transfer relation to a primary image-forming member to transfer the toner image from the primary image-forming member to the ITM. The ITM then transfers the image to a receiver sheet. A cleaning brush including plural individual brush fibers in engagement with the ITM removes residual toner from the ITM. The fibers each include an electrically conductive core and a surrounding substantially nonconductive annular portion. An electrically conductive backing secures the fibers and is adapted to electrically induce a potential from the backing to the cores of the fibers. The backing is substantially electrically insulated from the electrically conductive cores of the fibers. An electrical potential is established on the backing which is induced upon the cores of the fibers to attract remnant toner from the ITM to the brush.

International Classification:

G02B 514

US Classification:

350 9614

Abstract:

Optical modulators and methods of modulating light include introducing light to an optical wave guide from a light source. The wave guide is formed of an elastomer film which is deformable by a mechanical or electrostatic force acting to change the cross section of the film and thereby modulate the light passing through the wave guide.
