Abstract: A failure diagnosis apparatus according to the present disclosure is applied to a variable compression ratio mechanism that can switch the compression ratio of an internal combustion engine between at least a first compression ratio and a second compression ratio lower than the first compression ratio. When the variable compression ratio mechanism is controlled so as to set the compression ratio of the internal combustion engine to the second compression ratio, the failure diagnosis apparatus advances the ignition timing of one cylinder to a knock inducing ignition timing more advanced than the MBT that does not lead to the occurrence of knock if the actual compression ratio of that cylinder is the second compression ratio but leads to the occurrence of knock if the actual compression ratio of that cylinder is the first compression ratio and diagnoses failure of the variable compression ratio mechanism on the basis of whether knock occurs or not.

Abstract: It is possible to determine the biological state of the driver of a vehicle with high accuracy. In a biological state determination device, since a driver biological state which is the biological state of the driver is estimated on the basis of information representing the biological state of the driver, a weight is set for each driver biological state on the basis of information representing the level of possibility of erroneously estimating the driver biological state, and each driver biological state is weighted on the basis of the set weight, the weighted driver biological state becomes information in which the possibility of erroneous estimation is taken into consideration. The presence/absence of an abnormality in the biological state of the driver is determined on the basis of a plurality of weighted driver biological states, thereby improving determination accuracy of the biological state of the driver of the vehicle.

Abstract: A normal revolution number calculation unit calculates a normal revolution number of a driving motor generator in every control period, based on a signal from a rotational position sensor. A moving average calculation unit calculates a moving average revolution number of the normal revolution number given in every control period. A predicted revolution number calculation unit determines whether or not the revolution number of the motor generator is in an increasing state, from the locus of the moving average revolution number. Determining that the revolution number of the motor generator is in the increasing state, the predicted revolution number calculation unit calculates a predicted revolution number based on respective moving average revolution numbers in the present and preceding control periods. The calculated predicted revolution number is set to be used as a control revolution number and output to a motor control unit and a torque command calculation unit.

Abstract: An internal combustion engine wherein an SOx trap catalyst (12), an NOx storage catalyst (14), and a fuel addition valve (15) are arranged in an engine exhaust passage. When making the air-fuel ratio of the exhaust gas flowing into the NOx storage catalyst (14) the stoichiometric air-fuel ratio or rich so as to make the NOx storage catalyst (14) release NOx, additional fuel is supplied into the combustion chamber (2) and fuel is added from the fuel addition valve (15). At this time, the amount of additional fuel to the combustion chamber (2) is controlled so that the air-fuel ratio of the exhaust gas exhausted from the combustion chamber (2) becomes the smallest in the range where the SOx trap catalyst (12) does not release SOx.

Abstract: In an apparatus A in which electrode powder 10 is allowed to adhere via the electrostatic force to an electrolyte membrane that serves as a substrate 2 so as to form a catalyst layer, a screen 5 is held in a state of non-contact with the substrate 2, and a voltage is applied therebetween. The electrode powder 10 is allowed to adhere to an elastic feed roller 7, and the feed roller 7 is allowed to rotate in contact with the screen 5 by pressure. The electrode powder 10 is dispersed toward the substrate 2 so as to stably adhere thereto via both the electrostatic force and the extruding force of the elastic body. Variation of thickness and collapse of the outline are extremely reduced on the catalyst layer to be transferred and formed on the substrate (electrolyte membrane) via the electrostatic force using a conventionally used mesh-like screen so as to obtain a membrane electrode assembly with a high product manufacturing accuracy.

Abstract: A vehicle interior member with an air bag includes an air bag door portion that can be made to be invisible and of improved construction. The vehicle member includes a skin molded to a substrate. The skin includes a tear line formed by a diagonal cut portion. In the vicinity of a lateral tear line of the skin side tear line, a projecting portion is provided on a lower mold to form a groove portion of the substrate along the diagonal cut portion so as to intercept a flow of a resin from the cutting direction of the diagonal cut portion. Therefore, as the resin flows in a reverse direction to the cutting direction of the diagonal cut portion at an opening portion thereof, a flow of the resin into a PP foam layer of a three-layer skin through the opening portion of the diagonal cut portion can be suppressed. This prevents the PP foam layer from being melted and damaged.

Abstract: A cut-back pressure control device for a multi-speed automatic transmission includes a cut-back valve that has a spool which is controlled by both hydraulic pressure which changes in response to shifting of a sub-transmission unit between high-speed and low-speed modes and a hydraulic pressure which is established by the operation of the main transmission unit at 2nd or higher speeds. The spool is moved to a position where it interrupts the cut-back pressure when the main transmission unit selects the 1st speed while the sub-transmission unit is in the low-speed mode, whereas, when the sub-transmission unit is in the high-speed mode or when the main transmission unit selects the 2nd or a higher speed, the spool is held at a position at which it permits the supply of the cut-back pressure.
