| 20090059388 | Zoom lens and imaging apparatus - The invention relates to a zoom lens and an imaging apparatus, and more particularly to a slimmed-down zoom lens well fit for imaging apparatus inclusive of video cameras and digital cameras. The zoom lens comprises, in order from its object side, a first lens group having negative refracting power, a second lens group having positive refracting power, a third lens group having negative refracting power and a fourth lens group having positive refracting power. The first lens group consists of one negative component wherein one negative lens and one positive lens are cemented together. Upon zooming from the wide-angle end to the telephoto end and the second lens group moves toward the object side with a decreasing spacing between the first lens group and the second lens group, a changing spacing between the second lens group and the third lens group and a changing spacing between the third lens group and the fourth lens group. | 03-05-2009 |

| 20120028107 | BATTERY PACK - A battery pack includes: a plurality of batteries; a housing for containing the batteries; and at least one partition plate for separating the batteries from one another. The at least one partition plate includes a metal mesh and a heat insulating layer disposed on each side of the metal mesh. The heat insulating layer includes a foam material capable of foaming at a temperature of 110° C. or more and 200° C. or less, so that the thickness of the heat insulating layer increases when the foam material foams. Even when one of the batteries contained in the battery pack generates abnormal heat, the conduction of the heat to other batteries can be effectively suppressed. | 02-02-2012 |
