Filed:

Sep 7, 2004

Appl. No.:

10/935775

Inventors:

Xin Liang Li - Pomona CA, US

International Classification:

G02C009/00

US Classification:

351 47, 351 57

Abstract:

An auxiliary frame for detachably mounting in front of a spectacle frame includes a mounting frame and a retention arrangement. The mounting frame supports two shelter lenses for detachably mounting on a spectacle bridge. The retention arrangement includes two guiding members and two urging members. The two guiding members are rearwardly extended from two inner sides of the shelter lenses respectively and defined a guiding distance between the two guiding members which is smaller than the lens distance of the spectacle frame. The two urging members define an urging distance which is larger than the lens distance of the spectacle frame, such that when the guiding members are extended at the two inner sides of the spectacle lens respectively, the two urging members are adapted for applying an urging force against the two inner sides of the spectacle lens respectively.

Appl. No.:

11/181292

Assignee:

International Rectifier Corporation - El Segundo CA

International Classification:

H01L 29/76

US Classification:

257328, 257330, 257331

Abstract:

A vertical conduction trench FET has a plurality of trenches containing conductive polysilicon gates. The mesas between the trenches have a source diffusion region connected to a common source electrode. The trenches are spaced so that the depletion regions induced by the trench gate will overlap to pinch off conduction through the mesa to turn off the device. The gate potential is pulsed. The polysilicon in the trenches may be separated into two insulated portions. The pulses may be applied simultaneously or sequentially to the polysilicon gates.

Inventors:

Xin Li - Pomona CA, US

International Classification:

G02C 11/02

US Classification:

351052000

Abstract:

A spectacle set includes at least a decorative frame for supporting two lenses in position. The decorative frame includes two lens rims which are shaped and sized corresponding to the lenses, a bridge extended between two inner sides of the lens rims, two side extensions provided at two outer sides of the lens rims for coupling a pair of temples respectively, and a free-hand securing device detachably mounting the two lenses on the lens rims respectively in a toolless manner.

Inventors:

Xin Li - Pomona CA, US

International Classification:

G02C 7/08

US Classification:

351057000

Abstract:

A spectacles set includes a lens frame, a decorative frame and a lens engaging arrangement. The lens frame includes two lenses and a lens retention arrangement spacedly supporting the two lens in position. The decorative frame includes two lens rims defining two lens areas respectively, a bridge extending between two inner sides of the lens rims, and two side extensions extending at two outer sides of the lens rims. The lens engaging arrangement is provided at a rear side of the decorative frame to detachably engaging with the lens frame at a position that when the lens retention arrangement is detachably mounted at the rear side of the decorative frame in a hidden manner, the two lenses are alignedly positioned at two lens areas respectively so as to keep an aesthetic appearance of the decorative frame with the two lenses.
