Appl. No.:

10/137629

Inventors:

Richard Hong - Los Angeles CA, US

International Classification:

G09F013/00

US Classification:

040/557000

Abstract:

A self-illuminating street sign system comprises a base panel, reflective surfaces attached on each upper surface of the base panel, translucent boards supported by the base panel to incorporate a description including a street name. An ambient light from above the street sign system is reflected by the reflective surface and directed toward the boards to brighten the description.

Filed:

Dec 18, 2008

Appl. No.:

12/338056

Inventors:

Richard J.K. HONG - Sunnyvale CA, US

Assignee:

SANDISK CORP. - Milpitas CA

International Classification:

H02H 9/04

US Classification:

361 56

Abstract:

Methods and devices of the invention include an electrostatic discharge (ESD) protection circuit. This circuit includes rise time dependent activation circuitry capable of detecting a slew rate of an input signal and capable of determining whether the slew rate of the input signal is greater than a threshold value. For an ESD event said activation circuitry generates a trigger signal. Additionally, the activation circuitry is coupled with the ESD dissipation duration control circuitry which is further coupled with an ESD dissipation circuit. This arrangement enabling the duration control circuit to be activated by the trigger signal which responds by producing an activation signal that activates the ESD dissipation circuitry and that controls the length of time the dissipation circuit remains active. The ESD dissipation circuitry includes a shunt that redirects the ESD energy away from the protected internal circuit. The ESD dissipation duration circuitry further configured to maintain shunting of the energy for a period of time sufficient to discharge of the ESD energy without damaging the protected circuitry.

International Classification:

C03B 20/00

US Classification:

65 2912, 65158

Abstract:

The present disclosure relates to methods for automated inspection of the orientation of a glass substrate () having a side that is coated and/or impregnated with a non-glass material (e.g., tin). One method () includes: picking up the glass substrate () by using an automatic lifting assembly (); inspecting a side of the glass substrate () with a sensor () so as to determine whether the inspected side is coated or impregnated with the non-glass material; determining whether the glass substrate () is correctly oriented based upon the inspection results; and using the automated lifting assembly () to place the glass substrate () on a conveyor () in response to determining that the glass substrate () is correctly oriented.

US Classification:

361 56

Abstract:

Methods of the invention include an electrostatic discharge (ESD) protection method capable of detecting a slew rate of an input signal and capable of determining whether the slew rate of the input signal is greater than a threshold value. For an ESD event having a slew rate in excess of the threshold value said method generates a trigger signal which generates an activation signal that activates the ESD dissipation circuitry and that controls the length of time the dissipation circuit remains active. The method further comprises shunting the ESD energy away from a protected internal circuit. The method maintaining the shunting of the energy for a period of time sufficient to discharge of the ESD energy without damaging the protected circuitry.

Assignee:

Applied Materials, Inc. - Santa Clara CA

International Classification:

C23C 1434

US Classification:

20419212

Abstract:

The present invention generally provides an apparatus and a method for physical vapor deposition of a metal onto a substrate comprising a physical vapor deposition chamber and a target disposed in an upper portion of the chamber. The target comprises a backing plate having a central portion and a flange portion attachable to the physical vapor deposition chamber, a sputterable portion extending from the central portion of the backing plate, and an annular ridge disposed on a surface of the flange portion. Preferably, the sputterable portion of the target includes a restriction side wall that restricts entry of plasma and back-scattered particles into the dark space gap between an upper shield and the target.

Assignee:

Applied Materials, Inc. - Santa Clara CA

International Classification:

B05C 1300
B05C 1302
B05C 2100

US Classification:

118503

Abstract:

A method and apparatus is provided for clamping and shielding the edge of a substrate useful in electronic device fabrication. A shadow ring is formed by an inward radial extension of the top surface of a generally annular shaped clamp ring. The shadow ring portion overhangs but does not contact the top surface of a substrate being processed. A smoothly tapered substrate contact surface extending from the outer diametrical extent of the shadow ring bottom surface to the bottom surface of the clamp ring is sized and adapted to engage the outer edge of a substrate. The substrate contact surface aligns the clamp ring to a substrate support member and a substrate to the substrate support member and the clamp ring as the substrate is lifted vertically.
