Filed:

Feb 5, 2009

Appl. No.:

12/366141

Inventors:

Curtis Dove - Pueblo CO, US

Assignee:

Asia Union Electronic Chemical Corporation - Kaohsiung County

International Classification:

H01B 13/00

US Classification:

216 20, 216 83, 216 99, 136256, 136259, 438 68, 438690, 438753

Abstract:

Methods for performing damage etch and texturing of single crystal silicon substrates, particularly for use as solar cells or photovoltaic cells. Damage etch with a TMAH solution followed by texturing using solution of KOH or NaOH mixed with IPA is particularly advantageous. The substitution of some of the IPA with ethylene glycol further improves results. Also disclosed is a process that combines both damage etch and texturing etch into a single step.

International Classification:

B29C 4514
B29C 4576

US Classification:

264 401

Abstract:

A plastic injection molding/encapsulation apparatus for the peripheral encapsulation of a glass workpiece which is equipped with an optical sensing device including a light source, a light detector, and a light reflector to detect possible glass breakage of the workpiece and thus automatically shutting down the plastic injection process to avoid damage to the mold.

Hughes Aircraft Company - Los Angeles CA

International Classification:

G01B 902

US Classification:

356 45

Abstract:

An instrument of measuring motion of a vibratory system, such as an ultrasonic bonder, employs a laser (10) that receives within its lasing cavity light transmitted (24) to the object (26) to be monitored and retroreflected (24), so that oscillations within the laser cavity experience interference peaks corresponding to the phase relation between the outgoing and incoming laser beams (24). The interference peaks of the beam within the cavity are counted to provide an indication of motion of the reflecting object. Sensitivity is enhanced by choosing a front reflector (14) of the laser cavity to have a transmissivity at the frequency of interest that is selected to achieve maximum interference peak values. The laser cavity length is selected to cause the laser to have no more than two modes at the output frequency of interest, thereby avoiding beat frequencies that approach the frequency of vibration of the mechanical system of which motion is being observed.
