Abstract: A dental floss applicator of this invention comprises a housing, a dental floss stick, a floss spool, a spring rack, a take-up wheel, and a rotary knob with a springy ratchet on the inside. The spring rack has a stop portion engaged with a gear wheel fastened to the floss spool to stretch the dental floss, and a press portion extending to the outside of the housing for pressing by the user to loosen the dental floss on the dental floss stick. The springy ratchet releases the stop portion of the spring rack step by step upon rotation of the rotary knob, allowing the used segment of the dental floss to be taken up.

Abstract: A white-light emitting semiconductor device includes a first light-emitting die, a second light-emitting die, a photostimulable luminescent substance, and a holding assembly. The first light-emitting die emits a first radiation having a first wavelength range. The second light-emitting die emits a second radiation having a second wavelength range, and a third radiation having a third wavelength range different from the second wavelength range.

Abstract: A broad-spectrum Al(1-x-y)InyGaxN light emitting diode (LED), including: a substrate, a buffer layer, an N-type cladding layer, at least one quantum dot emitting layer, and a P-type cladding layer. The buffer layer is disposed over the substrate. The N-type cladding layer is disposed over the buffer layer to supply electrons. The quantum dot emitting layer is disposed over the N-type cladding layer and includes plural quantum dots. The dimensions and indium content of the quantum dots are manipulated to result in uneven distribution of character distribution of the quantum dots so as to increase the FWHM of the emission wavelength of the quantum dot emitting layer. The P-type cladding layer is disposed over the quantum dot emitting layer to supply holes. A broad-spectrum Al(1-x-y)InyGaxN yellow LED may thus be made from the LED structure of this invention, with an emission wavelength at maximum luminous intensity falling within a range of 530˜600 nm, and FWHM within a range of 20˜150 nm.
