52253775, Jul 6, 1993

Filed:

May 3, 1991

Appl. No.:

7/695185

Inventors:

John R. Hines - Richardson TX
Ralph H. Johnson - Plano TX
Richard Kirkpatrick - Richardson TX

Assignee:

Honeywell Inc. - Minneapolis MN

International Classification:

H01L 21306

US Classification:

437228

Abstract:

A structure is formed from two layers of material having opposite conductivity types. A first region is formed within the structure, and extends at least in part into a layer to be etched. A surface of the structure is then masked and etched. The result is a microstructure which varies with the conductivity type and geometry of the region formed and etchant used.

Assignee:

Honeywell Inc. - Minneapolis MN

International Classification:

G01L 708
G01L 906

US Classification:

73727

Abstract:

A pressure transducer having means for improving the linearity and sensitivity of an output signal from the pressure transducer. Ribs and bosses are introduced in the diaphragm region to collect the moments caused by a difference in pressure on the two sides of the diaphragm and thus improve device sensitivity. In addition, the ribs and bosses prevent stretching of the piezoresistors thus improving the linearity of the device. A constraint can also be included to improve the alignment of the piezoresistors thus improving the linearity of the device.

Appl. No.:

6/717740

Inventors:

John R. Hines - Garland TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G05F 320

US Classification:

323317

Abstract:

A current switch whose turn-on and turn-off voltages are independent of temperature includes a transistor switch circuit having two input transistors to which a differential voltage is applied, two sensing transistors for sensing turn-on and turn-off voltages respectively, and an output transistor controlled by the sensing transistors. A differential voltage sensing circuit including a differential transistor pair is connected to receive the differential voltage at the inputs of the transistors and to deliver the differential voltage to the transistor switch circuit. A biasing current source is provided to supply biasing currents which vary as a function of temperature to the input and sensing transistors of the switch circuit, and a biasing current source is provided to supply a biasing current which varies as a function of temperature squared to the differential transistor pair.

International Classification:

C22B 1300
A61K 4300

US Classification:

423 2

Abstract:

A method and apparatus for providing radionuclides of bismuth-212 and lead-212. Thorium-228 and carrier solution starting material is input to a radiologically contained portion of an isotopic generator system, and radium-224 is separated from thorium-228 which is retained by a strongly basic anion exchange column. The separated radium-224 is transferred to an accessible, strongly acidic cationic exchange column. The cationic column retains the radium-224, and natural radioactive decay generates bismuth-212 and lead-212. The cationic exchange column can also be separated from the contained portion of the system and utilized without the extraordinary safety measures necessary in the contained portion. Furthermore, the cationic exchange column provides over a relatively long time period the short lived lead-212 and bismuth-212 radionuclides which are useful for a variety of medical therapies.

Appl. No.:

6/656204

Inventors:

John R. Hines - Garland TX

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G05F 326

US Classification:

323315

Abstract:

A linear voltage-to-current converter which operates entirely from a single power supply, accepts input voltages as low as one diode-drop from ground, and accepts input voltages greater than the power supply voltage is disclosed. Current mirrors sense an input voltage converted to a current through a resistor and reflect the current as one component of the output current. Additional compensation circuits provide a second component of the output current which compensates for non-linearities.

Appl. No.:

6/656206

Inventors:

John R. Hines - Garland TX

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H03F 345

US Classification:

330289

Abstract:

A temperature dependent amplifier which may be used as a system building block in temperature compensation applications is disclosed. A temperature dependent signal source generates a first order temperature dependent signal which is multiplied by an input signal and divided by a temperature reference signal to produce an output which varies in direct proportion with temperature changes. The input signal is multiplied by the temperature reference signal and divided by the temperature dependent signal to produce an output which varies inversely proportional to temperature changes.

International Classification:

C22B 3/00
B03D 1/02

US Classification:

252 61, 75711, 423304, 209 3

Abstract:

Methods for purifying one or more value materials are provided. The method can include contacting an aqueous mixture comprising a value material and a contaminant with a dispersant and a depressant to produce a treated mixture. A weight ratio of the dispersant to the depressant can be from about 1:1 to about 30:1. The method can also include recovering a purified product comprising the value material from the treated mixture. The purified product can have a reduced concentration of the contaminant relative to the aqueous slurry.
