42571111, Mar 17, 1981

Filed:

Oct 3, 1979

Appl. No.:

6/081418

Inventors:

Jack E. Soohoo - Fountain Valley CA
Michael J. McNutt - Yorba Linda CA
Cecil L. Hayes - Placentia CA
Richard A. Gudmundsen - Santa Ana CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

G11C 1300

US Classification:

365114

Abstract:

A digital-to-analog optical recorder incorporating both CCD and integrated optics technologies which is fabricated as a single integral unit including an electro-optical layer portion and a semiconductor layer portion. Sampling circuits and digital-to-analog converters are implemented on the semiconductor layer portion using CCD technology, and a plurality of optical channel waveguides and electro-optical modulators are implemented on the electro-optical layer portion. Each digital signal is converted into two complementary light spots at the output of the recorder.

Appl. No.:

7/809929

Richard A. Gudmundsen - Santa Ana CA

International Classification:

B63H 1102

US Classification:

440 38

Abstract:

This is a water-jet propulsion system employing a cyclic air-pump to induce a cyclic reduced-pressure inside a vacuum-chamber which has front and rear valves, the front facing the predominant direction of travel. The front valve opens near the start of a "pump down" portion of the cycle to allow a jet of water to be admitted at the bottom of said boat from the "rest system" outside, into the less-than-atmospheric-pressure interior, the front or intake valve closing after the "jet-slug" is fully formed. The internal pressure changes so that when said jet-slug reaches said exit port, said chamber pressure is atmospheric and the opened exit port valve allows the water-slug to exit the chamber just prior to the beginning of a new cycle. Friction and pumping losses are minimal as the water jet is not in contact with walls over most of its trajectory, and said pump is pumping air. Low final water-velocity with respect to the rest system, high volume flow, leads to high propulsion efficiency.

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

G02B 514

US Classification:

350 9614

Abstract:

A CCD driven integrated optical modulator array including an array of chirp grating optical lenses implemented on the surface of an electro-optical crystal such as LiNbO. sub. 3 or LiTaO. sub. 3, a plurality of channel waveguides and a thin metal film pattern on the surface of the waveguides for modulating the optical waveform in each channel. The thin metal film form planar capacitors, each of the capacitors being electrically connected to the output circuit of a corresponding semiconductor device, such as a CCD array. The CCD array is implemented on a semiconductor wafer bonded to the electro-optical crystal. Signals in each optical channel in the electro-optical crystal are thereby modulated by corresponding circuit elements associated with corresponding CCD channels implemented on the major surface of the semiconductor wafer.
