20100184882 | ADHESIVE FOR TEETH-STRAIGHTENING MEMBERS - The present invention discloses an adhesive for orthodontic attachments, which contains (A) a polymerizable monomer, (B) a polymerization initiator and (C) a fluorescent dye and, when cured, exhibits a fluorescence spectrum having a peak at 400 to 800 nm. As the polymerization initiator (B), there is preferably used a compound which generates a radical through the transfer of hydrogen between two components, or a compound which generates a radical species through intramolecular cleavage. As the fluorescent dye (C), a coumarin type dye is used preferably. | 07-22-2010 |

20110069396 | ZOOM LENS - The invention relates to a new mechanism for permitting a zoom lens to focus on a short distance subject by moving a focusing lens group in an amount that varies in an optical axis direction depending on a zooming position. The zoom lens comprises, in order from its object side, a positive first lens group, a negative second lens group and a positive third lens group. Zooming is implemented while the space between adjoining lens groups is varied, and focusing on a short distance subject is implemented by moving the negative second lens group in an amount that varies in the optical axis direction depending on a zooming position. The negative second lens group comprises a negative front unit G | 03-24-2011 |
