The object of the present invention is to provide an explosion-proof safety valve assemblage having a lead cap which allows some of the manufacturing man-hour in the process such as precision working and positioning to be deleted, since the lead cap is integrally formed with an explosion-proof safety valve and serves to provide a current circuit in a battery in place of a conventional one composed of lead plate or lead wire which requires such precision working and positioning operations, and to provide a closed secondary battery using the above mentioned safety valve assemblage. An explosion-proof safety valve assemblage for use in a closed secondary battery comprising an outer container, an electrode element, consisting of a positive electrode, negative electrode, and a separator, accommodated in said outer container, wherein said safety valve assemblage is sealingly secured to an open end portion of said outer container via an insulating gasket integrally with a closing cap, and it consists of an explosion-proof safety valve element, a coreless disc-shaped insulator, and a lead cap formed of a metal substrate and a metal foil laminated to the metal substrate, substantially the center of which is provided with an opening, and a closed secondary battery using the above mentioned safety valve assemblage.

A power source device includes a control circuit which controls switching elements in full-bridge arrangement so as, in decreasing an output to a load, to substantially equalize ON timing of one of two switching elements at diagonal position to the other of them with ON period of the one switching element shortened, that is, with ON duty ratio of the one switching element decreased. Switching operation of the elements in this event is not made to be in the hard switching operation, and a range in which the output to load can be controlled without increasing any stress or noise is thereby broadened, whereby it is enabled to minimize varying width of switching frequency and to attain a wide range control of the output to load without causing any one of the switching elements to be in the hard switching operation.
摘要:
A liquid crystal display device comprising a liquid crystal display panel and a light guide plate arranged in a rear side of the liquid crystal display panel. The liquid crystal display panel is of a substantially spherical shape, and the liquid crystal display panel is fitted at a front side of the light guide plate such that a proximity of a central portion of the liquid crystal display panel is outwardly bulged. There can be prevented display deficiencies (paddling) owing to interference between the liquid crystal display panel and the backlighting unit or between the former and the casing. Moreover, since no interference exists between the liquid crystal display panel and the backlighting unit or between the former and the casing, sheets such as the diffusing sheet will not be wrinkled, and the brightness of the backlighting unit can be maintained to be uniform.

A discharge lamp lighting device employs first and second series circuits, each series circuit including two switching elements and a connecting point located therebetween. The first and second series circuits are both connected in parallel across a DC voltage source. A load circuit, including a discharge lamp, is connected between the two connecting points in the first and second series circuits. ON/OFF timing of the switching elements in the first series circuit varies between in-phase and 180 degrees out-of-phase from ON/OFF timing of the switching elements in the second series circuit. The ON period ratio of the switching elements is different in at least one of the first and second series circuits. The device allows dimming of the discharge lamp over a wide range, and lighting of the discharge lamp with a small supplied power.
