摘要:
The present invention provides a water based lithium secondary battery that can inhibit deteriorations in capacity owing to charge-and-discharge operations and maintain a high capacity even after it is charged and discharged repeatedly. The water based lithium secondary battery includes a positive electrode, a negative electrode, a separator 4 sandwiched between these, and an aqueous electrolyte solution obtained by dissolving an electrolyte made of a lithium salt in a water based solvent. As the water based solvent, a pH buffer solution is employed. The buffer solution is obtained by dissolving an acid and its conjugate base's salt, a base and its conjugate acid's salt, a salt made from a weak acid and a strong base, a salt made from a weak base and a strong acid, or a salt made from a weak acid and a weak base in water.

摘要:
A first insulating film is formed on a semiconductor substrate. A second insulating film made of insulating metal nitride is formed on the first insulating film. A recess is formed through the second insulating film and reaches a position deeper than an upper surface of the first insulating film. A conductive member is buried in the recess. A semiconductor device is provided whose interlayer insulating film can be worked easily even if it is made to have a low dielectric constant.

A control device for a drive line of a vehicle, in which a drive line from a power source to drive wheel includes a wheel control for controlling the speed of the wheels, and a connection mechanism for increasing/decreasing a torque transmission capacity between the power source and the drive wheels. The control device includes a trouble detector for detecting that the wheel control is in a situation unable to control the speed of the wheels normally. A braking detector detects that a braking operation to brake the rotation of the wheels is executed. And, a torque interruption control reduces the torque transmission capacity by the connection mechanism, when it is detected by the trouble detector that the wheel control cannot control the speed of the wheels normally and when it is detected by the braking detector that the braking operation to brake the rotation of the wheels is executed.

A semiconductor device having a multi-layered wiring structure containing a copper layer, comprises a first insulating film formed over a semiconductor substrate, a first copper pattern buried in the first insulating film, a cap layer formed on the first copper pattern and the first insulating film and made of a substance a portion of which formed on the first copper pattern has a smaller electrical resistance value than a portion formed on the first insulating film, second insulating films formed on the cap layer, and a second copper pattern buried in a hole or a trench, which is formed in the second insulating films on the first copper pattern, and connected electrically to the first copper pattern via the cap layer.
摘要:
A method and apparatus for controlling a continuously variable transmission of a motor vehicle includes a controller that controls the speed ratio of the continuously variable transmission in accordance with a predetermined shift condition. The method and apparatus perform shift control in a specific manner during an operation of an anti-lock brake system, for example, by smoothing at least one of the rotational speed of the input shaft and the rotational speed of the output shaft, reducing a rate of change in the speed ratio during down shifting, restricting upshifting of the CVT, increasing an amount of hydraulic oil delivered from an oil pump, and/or increasing belt clamping force.
