Patent number: 8297260Abstract: A fuel supply system includes a covering member, a subtank, a first housing on the covering member to project toward the subtank, terminals in the first housing, a second housing fitted to the first housing, and lead wires in the second housing connected respectively to the terminals. The first housing includes a fitting recess opening toward the subtank, and a partition wall dividing the recess into spaces, each of which receives a corresponding terminal. The second housing includes a fitting projection fitted into the recess, a slit dividing the projection into blocks, each of which receives a corresponding terminal, the partition wall being inserted in the slit, and axial holes, each of which accommodates a corresponding wire. Each wire includes a corresponding one of elastic seal members. Each seal member seals a gap between a corresponding wire and a wall surface of a corresponding axial hole.Type: GrantFiled: January 7, 2010Date of Patent: October 30, 2012Assignee: Denso CorporationInventor: Kengo Masuda

Patent number: 6671201Abstract: A method of writing data into a semiconductor memory device including a memory cell to which a power supply potential and a ground potential are provided is disclosed. The method may include generating a negative voltage (GNDL) lower than the ground potential and providing complementary data signals to a bit line pair when writing data to a memory cell wherein the low one of the complementary data signals is essentially the negative voltage. In this way, compensation for a potential increment which may be caused due to a wiring resistance, or the like, of a bit line (BL1) may be provided.Type: GrantFiled: April 1, 2002Date of Patent: December 30, 2003Assignee: NEC Electronics CorporationInventor: Kengo Masuda
