Abstract: A laser device for photocoagulation surgery is disclosed, wherein the laser device includes a multi-wavelength laser source having a first direction and a second direction different from the first direction. The laser device includes a positioning light source, a first laser light source, a first lens, a second laser light source, a second lens, a third laser light source, a third lens, a fourth laser light source and a fourth lens. The positioning light source configured to project a positioning visible light along the first direction, wherein the positioning visible light has a specific wavelength being about 635 nm. The first laser light source configured to project a first laser light having a first wavelength along the second direction. The first lens disposed in a main optical path of the positioning visible light, and configured to receive the first laser light and reflect the first laser light along the first direction.

Abstract: A transistor includes a gate structure over a substrate, wherein the substrate includes a channel region. The transistor further includes a source/drain (S/D) in the substrate adjacent to the gate structure. The transistor further includes a lightly doped drain (LDD) region adjacent to the S/D, wherein a dopant concentration in the first LDD is less than a dopant concentration in the S/D. The transistor further includes a doping extension region adjacent the LDD region, wherein the doping extension region extends farther under the gate structure than the LDD region, and a maximum depth of the doping extension region is 10-times to 30-times greater than a maximum depth of the LDD.

Abstract: A vehicle cesspool level sensor includes a mounting base, a stainless steel detection tube welded to the bottom side of the mounting base to hold a detection circuit on the inside, an end cap welded to the bottom end of the stainless steel detection tube, a float axially movably mounted the detection tube and movable, the float having two magnets symmetrically disposed at two sides and adapted to induce the detection circuit, a stainless steel strainer fastened with the top end to an endless locating flange at the bottom side of the mounting base, and a strainer cover capped on the bottom end of the stainless steel strainer and fastened to the end cap with a screw.
