Abstract: A method of estimating life of a nickel-metal hydride battery that accommodates a positive electrode plate and a negative electrode plate facing the positive electrode plate with a separator therebetween and containing a hydrogen absorbing alloy together with an electrolyte is disclosed. A charge phase of charging the nickel-metal hydride battery and a discharge phase of discharging the nickel-metal hydride battery after the charge phase constitutes one cycle for charge/discharge of the nickel-metal hydride battery. The method includes: determining a rate of change after one charge/discharge cycle of a surface area of the negative electrode plate which is a boundary face in contact with the electrolyte, and determining an amount of corrosion of the hydrogen absorbing alloy based on the rate of change accumulated for n charge/discharge cycles to estimate the life of the nickel-metal hydride battery based on the amount of corrosion.

Abstract: A control device for a lockup clutch is provided in which when control region determination device determines that a vehicle speed and an opening degree of an accelerator pedal are in the tight region of the lockup clutch, even if the water temperature of cooling water of the or the oil temperature of hydraulic oil of the transmission is less than a predetermined temperature, engagement permission device permits engagement of the lockup clutch. It is therefore possible to improve the fuel economy of the vehicle by increasing the frequency of engagement of the lockup clutch without affecting the function of the lockup clutch. The control device even functions when the lockup clutch is engaged at low temperatures, when the engagement responsiveness is low, because the oil temperature of the hydraulic oil is low and the viscosity is high.

Abstract: An oil pressure control device includes: line pressure adjusting means for adjusting the line pressure; line pressure switching means for switching, in two stages, the line pressure adjusted by the line pressure adjusting means; a linear solenoid valve that adjusts a required oil pressure for engaging frictional engagement elements with one another by engagement force, which is required thereby, by adjusting a pressure of hydraulic oil with the line pressure; and control means for controlling a value of a current supplied to the linear solenoid valve. The control means performs control to differentiate the value of the current, which is supplied to the linear solenoid valve in order to adjust (obtain) the same required oil pressure, in response to the line pressure switched by the line pressure switching means.

Abstract: Mapped data of line pressure set to any of high pressure/low pressure regions on the basis of an engine load are stored in a storage section. A determining section 103 determines, on the basis of temperature of the hydraulic oil detected by an ATF temperature sensor 18, whether the mapped data the low pressure region is shifted in an enlarged direction. A state determining section 104 determines whether a throttle valve opening degree TH of the vehicle is totally closed or whether the line pressure is currently set to low line pressure. When the low pressure region is shifted in the enlarged direction and the throttle valve opening degree TH is totally closed or the line pressure is currently set to the low line pressure, a region changing section enlarges the low pressure region of the mapped data stored in the storage section.

Abstract: To power-consume noise currents flown in power source lines, etc. in non-uniform wiring modes to such a level that noise obstructions can be suppressed by using a resistance without a capacitor that causes series resonance phenomena. It is a line noise attenuator for purifying electromagnetic environments by attenuating noise currents superimposed on a conductor line which supplies a signal power to a load from a signal power source. The conductor line operates as an antenna which receives high frequency noise currents. The conductor line has an inductor which tolerates flows of a low frequency signal power, and a resistance for changing the high frequency noise currents to heat and consuming the heat with a resistance value which is so set, with respect to a resistance value of the inductor replaced with a pure resistance value, that the high frequency noise current blocked at the inductor can be flown.

Abstract: Fuel economy of a vehicle is improved by enlarging a low line pressure region of mapped data (hydraulic pressure control characteristics) on the basis of temperature of hydraulic oil. The mapped data of line pressure set to any of high pressure/low pressure regions on the basis of an engine load are stored in a storage section 101. A determining section 103 determines, on the basis of temperature of the hydraulic oil detected by an ATF temperature sensor 18, whether the mapped data the low pressure region is shifted in an enlarged direction or not, and a state determining section 104 determines whether a throttle valve opening degree TH of the vehicle is totally closed or not or whether the line pressure is currently set to low line pressure or not.

Abstract: A noise filter of the present invention includes an inductor and a resistor connected in parallel with each other. A power supply frequency current does not pass the resistor but passes through the inductor with no loss. On the other hand, a high frequency noise current including a resonance frequency current, does not pass the inductor but is dissipated at the resistor. Therefore, the noise filter does not charge noise power and so does not suffer from a problem due to power discharging. The resonance frequency current caused by the noise filter and the earth capacitance is also dissipated at the resistor. Therefore, no problem is caused by the resonance frequency current.

Abstract: A noise filter 10 of the present invention includes an inductor 71 and a resistor 11 connected in parallel with each other. A power supply frequency current bypasses the resistor 11 but passes through the inductor 71. A high frequency noise current including a resonance frequency current, on the other hand, bypasses the inductor 71 but is dissipated at the resistor 11. Therefore, the noise filter 10 does not accumulate noise power and so does not suffer from a problem due to power releasing. The resonance frequency current caused by combination of inductance of the inductance and earth capacitance in the noise filter 10 is also dissipated at the resistor 11, thus giving rise to no problem of its own.

Abstract: In a seat structure having a side air bag device, a longitudinal groove (36) is formed in a seat back pad (14) along the longitudinal direction of the seat back pad, and an insert wire (40) which holds a seat outer cover, is embedded in the longitudinal groove (36). Bent portions (44) are formed in portions of the insert wire (40), which portions oppose the air bag device. Each of the bent portions (44) is bent in a substantially U-shaped configuration, and a slab pad (46) is wound around an outer peripheral portion of a base portion (44A) of each bent portion. Further, the bent portions (44) of the insert wire (40) are each provided to extend rearwardly and diagonally toward the inner side of a seat back (10) so that the embedded length of the insert wire (40) embedded in the seat back pad (14) is made longer, and adverse influences on riding comfort are thereby suppressed.
