Title: Vehicle-mounted charger
Inventor: YOSHINAGA ROKU
IPC: G01R31/36
Filed: 1994-07-14
Abstract: PURPOSE:To prevent a fully charged secondary battery from being overcharged through quick charging by storing the charged state of a secondary battery when a first DC power supply is turned OFF and sustaining the charged state thus stored at the time of reclosing the first DC power supply. CONSTITUTION:A secondary battery 3 starts quick charging under the control of a microcomputer 2 when a cigar lighter is on. A timer is set to 1-2 hours. When the charging voltage drops after start of charging operation or when an abrupt temperature rise of a secondary battery 3 is detected, a transition is made to a low current charging operation with or without time lag of 1-2 hours. When a cigar lighter is turned OFF, the charging operation is stopped under control of a microcomputer 2. The microcomputer 2 is operated continuously with a car battery coupled directly therewith and stores the charged state in a memory. When the cigar lighter is turned ON again, the charged state stored in the memory of the microcomputer 2 is sustained. In other words, the quick charging operation is sustained when the power supply is turned OFF under quick charging state whereas the low current charge operation is sustained when the power supply is turned OFF under low current charge state thus sustaining the quick charging operation for the remaining time of the timer at the time of quick charging operation.

Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To sufficiently seal the gas without increasing the fastening force, and improve the yield in blanking of a material by forming multiple recessed parts in both surfaces of a reinforcing plate with arrangement patterns continued with a view in any directions from any position. SOLUTION: A compound sheet 4 is formed by adhering an expanded graphite sheet 2 to both surfaces of a reinforcing plate 1 formed of a metal thin plate. The both surfaces of the reinforcing plate 1 are formed with multiple hexagonal recessed parts 1c with a pattern continued with a view in any directions from any position. When an annular gasket is blanked from the compound sheet 4, pinched at a flange, and fastened by bolts, the expanded graphite sheet 2 is pushed into the recessed part 1c. Consequently, surface pressure of the expanded graphite sheet 2 at a position of the recessed part 1c is remarkably lowered, and the surface pressure is remarkably increased at a position of a part 1d except for the recessed part 1c, and the sufficient fastening pressure can be obtained for sealing of the gas without increasing the fastening force.  The sealing function can be secured even in the case where the gasket is cut from any position.
