  • Patent number: 7090520
    Abstract: A compact vehicle-mounted electrical outlet box offering a reliable plug blade detection function. The electrical outlet box is formed from synthetic resin rectangular case 1 which includes body 2 and cover 3. A pair of electrical plug blades 100 and 101 are inserted into plug blade insertion slots 5 located on the front surface of case 1 through which the plug blades contact two blade receiver parts 10. The forceful contact of plug blades 100 and 101 rotate two pivot levers 12 which convert the insertion force of plug blades 100 and 101 to a directional force. Two return springs 13 apply pressure to pivot levers 12 in a direction opposite to that applied by the insertion of plug blades 100 and 101. Printed circuit block 14, which is comprised of circuit base plate 14a to which each microswitch 14b is installed, is housed within case 1. The two pivot levers 12 are located at the approximate mid-point of body 2 between the two mutually facing blade receiver parts.

  • Patent number: 5791521
    Abstract: A liquid dispensing bag includes a bag body portion having a surface wall and a back wall formed of a flexible material having high gas barrier properties, and an elongated spout portion in which the surface wall and said back wall are projected in an elongated manner from a lower portion of the bag body portion. A flowpassage division area has the surface wall and the back wall welded integrally to divide a flowpassage toward the lower portion of the bag body portion. The flow passage division area is formed at a position close to the lower portion from the center of the bag body portion. The flowpassage division area is provided upwardly thereof with a pressure regulating area in which the surface wall and the back wall are welded. The flowpassage division area is formed in the central portion with a central flowpassage.
