  • Publication number: 20160046202
    Abstract: A vehicle power supply device includes: a plug socket to supply an external device with electrical power; and an external output switch configured to be switched between an on state in which the electrical power is supplied from a battery to the plug socket and an off state in which the supply of the electrical power is stopped. In a case where the external output switch is in the on state, when the vehicle transitions from a ready mode to an OFF mode, the switch control unit sets the external output switch to the off state along with the transition, and when the vehicle transitions from an ACC mode or an ON mode to the OFF mode, the switch control unit maintains the on state of the external output switch.

  • Patent number: 9246201
    Abstract: Even when temperature sensors (12, 13) used in a device for warming a battery (1) being not in use by using a battery-driven heater (2) have failed, the battery (1) is prevented from freezing. Based on a battery temperature (Tb) and an outside air temperature (Ta), times (?t1 to ?t8) during which Tb will decrease down to a warming start temperature (Tb_start) are each set to the next controller startup time (?t). A controller (9) is started up every ?t, at t2, t3, and t4, and checks whether Tb<Tb_start is satisfied or not. At t4 when Tb<Tb_start is satisfied, a heater (2) is battery-driven to warm the battery (1). After t0 when the outside air temperature sensor (13) fails, the outside air temperature (Ta) is set to a fixed value (Ta_const) and based on this Ta=Ta_const and the battery temperature (Tb), the above control is repeated.

  • Patent number: 9235180
    Abstract: A fixing device thermally fixes an unfixed toner image onto a recording sheet and includes: a rotatable heating element that is endless and includes a resistive heating layer that generates heat upon application of voltage; a power source for placing voltage across the resistive heating layer; an ammeter for measuring the electric current flowing through the resistive heating layer, and a controller for determining whether the resistive heating layer has a scratch by monitoring an amount of change between a value of electric current that flows through the resistive heating in absence of a scratch and a value of electric current actually measured by the ammeter. The resistive heating layer exhibits resistivity anisotropy satisfying R1<R2, where R1 and R2 denote a volume resistivity of the resistive heating layer in a direction of voltage application and that in a direction perpendicular to the direction of voltage application, respectively.

  • Patent number: 9162580
    Abstract: When a timer charge time zone is set by a timer charge reservation means for allowing a user to designate a predetermined timer charge time zone and a target charge amount, and timer charge is carried out from a timer charge start time previously designated, it is judged whether or not the timer charge start time should be advanced, at a time earlier by a predetermined time period than the timer charge start time. Owing to the judgment, charge of a battery can be completed at a predetermined time without enhancing a required capacity of a heater.

  • Patent number: 9136727
    Abstract: When warming-up of a battery is in progress (S12), a battery charge state at the warming-up start time of the battery is set to a battery hold capacity SOChold (S14, S15), and a charge power for the battery is controlled so that a battery charge state SOC is kept at SOChold. When a present time is in a timer charge reservation time (S11), the charge power for the battery is controlled so that SOC becomes a full charge state SOCfull (S17). Even if SOC has a tendency to temporarily decrease due to a rapid increase of heater consumption power just after start of warming-up of the battery, by keeping SOC at SOChold (SOC=SOChold), SOC can reach a full charge state as intended during the timer charge reservation time. A proportion of charge using low-priced midnight power is increased to a maximum then running cost can be suppressed.

  • Publication number: 20150214476
    Abstract: Manufacturing processes for phase change memory have suffered from the problem of chalcogenide material being susceptible to delamination, since this material exhibits low adhesion to high melting point metals and silicon oxide films. Furthermore, chalcogenide material has low thermal stability and hence tends to sublime during the manufacturing process of phase change memory. According to the present invention, conductive or insulative adhesive layers are formed over and under the chalcogenide material layer to enhance its delamination strength. Further, a protective film made up of a nitride film is formed on the sidewalls of the chalcogenide material layer to prevent sublimation of the chalcogenide material layer.
