US Patent:

45840288, Apr 22, 1986

Filed:

Sep 24, 1984

Appl. No.:

6/653559

Inventors:

Jacques I. Pankove - Princeton NJ
David E. Carlson - Yardley PA

Assignee:

RCA Corporation - Princeton NJ

International Classification:

H09L 21265

US Classification:

148 15

Abstract:

A p-type impurity in a silicon semiconductor structure is at least partially neutralized by exposure to atomic hydrogen. The subject method provides an excellent means of modifying the profile of the impurity. Suitable impurities include boron, aluminum, gallium and indium.

Filed:

Nov 3, 1977

Appl. No.:

5/848250

Inventors:

Alan E. Bell - East Windsor NJ
Brown F. Williams - Princeton NJ
David E. Carlson - Yardley PA

Assignee:

RCA Corporation - New York NY

International Classification:

H01L 3106

US Classification:

136 89TF

Abstract:

A photovoltaic device has a body which includes a thin film active region and a layer substantially transparent to solar radiation. The thickness of the transparent layer is such that a first antireflection condition is present for solar radiation at a wavelength which is relatively highly absorbed by the material of the active region. Furthermore, the combined thickness of the transparent layer and active region are such that a second antireflection condition is present for solar radiation at a wavelength which is poorly absorbed by the material of the active region. As a result of the prevailing antireflection conditions the solar radiation absorption efficiency of the photovoltaic device is increased.

Appl. No.:

8/939453

Inventors:

David L. Carlson - Harrison NJ

International Classification:

G10D 1302

US Classification:

84411R

Abstract:

A percussive instrument comprises two shells, each having open ends. The shells are positioned substantially end to end. Drum heads are positioned at the opposing open ends and between the two shells.

F17D 5/06
G01N 29/32
G01N 17/04
G01N 29/22

Abstract:

Embodiments of tuning fork-based sensors are disclosed. The sensors may include a measurement sensor that includes a diaphragm disposed on a proximal end and a plurality of forks extending from the diaphragm toward the distal end of the sensor. The diaphragm may have a domed geometry defining a curved surface. The plurality of forks may extending from the curved surface of the diaphragm toward the distal end and each of the plurality of forks may include a stub portion connected to the diaphragm, a stem portion, and a paddle portion. Some sensors, such as measurement sensors, may include a stem portion formed from a corrosive material. A reference sensor may be provided to compensate for changes in frequency measurements due to temperature, viscosity, or other environmental factors present in the environment where the sensors are deployed.
