An ECU executes a program including the steps of determining that a change speed solenoid is abnormal when a target speed ratio falls within a predetermined range, an upshift is recognized and the change speed solenoid is abnormal; determining that the change speed solenoid is normal when the change speed solenoid is not abnormal; determining that a belt pinch pressure solenoid is abnormal when the target speed ratio is substantially equal to a speed ratio γmin on a maximum speed-increase side and the target speed ratio is not substantially equal to an actual speed ratio; and determining that the belt pinch pressure solenoid is normal when the target speed ratio is substantially equal to the actual speed ratio.

A continuously variable transmission 18 changes a speed-change ratio γ so that an actual rotation speed NIN of an input shaft 36 coincides with a target rotation speed NIN* set based on a target output P*. A target output calculating portion 156 calculates a first target drive force related value P1* based on both an acceleration required amount Acc and a load of an auxiliary machine AUX, calculates a second target drive force related value P2* based on the acceleration required amount without considering the auxiliary machine load, and sets the second drive force related value as the drive force related value P* upon a vehicle regular running. Even when the auxiliary machine load fluctuates in the vehicle regular running the target output does not fluctuate, and prevention of fluctuation of the target output rotation speed increases the drivability in the vehicle regular running.

A flux contains resin having film forming ability, activator, solvent, and at least one complex selected from silver complex and copper complex. The flux is used when soldering is performed onto a circuit having electroless nickel plating or further having gold plating on the electroless nickel plating. Allowing a barrier layer of silver or copper to deposit on the surfaces of lands suppresses the diffusion of nickel into the melted solder alloy during soldering, and also prevents phosphorous concentration. This improves the bonding strength of soldering and suppresses the reduction deposition of silver and/or copper to portions other than circuit patterns.

An oil pressure control device, which changes a range of a vehicle transmission includes: a pressure adjusting device that engages or releases forward and reverse frictional-engagement devices by adjusting an oil pressure supply, a sensor that detects a range selected by a vehicle driver, and a controller that controls the clutch pressure adjusting device based on a signal from the sensor. When the stop range is selected after selecting the reverse (forward) range, a forward (reverse) range is selected. After supplying an initial oil pressure to the forward (reverse) frictional-engagement device, the pressure adjusting device is controlled so that the pressure decreases from the initial oil pressure to a predetermined oil pressure. Subsequently, the oil pressure is initially increased at a small increase rate from the predetermined oil pressure. After a predetermined time period has elapsed, the pressure adjusting device increases the oil pressure at a large increase rate.

In a method and an apparatus for manufacturing a semiconductor device which has a capacitor consisting of a layered structure of a lower electrode, a ferroelectric layer made of a composite metal oxide such as PZT and an upper electrode in a predetermined region on a semiconductor substrate, the lower electrode, the ferroelectric layer and the upper electrode are successively formed in an atmosphere isolated from the air. For the duration after forming the ferroelectric layer till starting the formation of the upper electrode, it is desirable to introduce a gas such as an inert gas or an inert gas with oxygen into the atmosphere in the vicinity of the substrate to keep the atmosphere within a predetermined pressure range.
