When alcohol mixing fuel is supplied to an internal combustion engine, an intake air flow rate is detected and a basic amplitude amount α of an upstream target air-fuel ratio abyfr corresponding to this detected intake air flow rate is calculated. Next, alcohol concentration in the fuel (in more detail, ethanol concentration Cetha) and a cooling water temperature (or an intake air temperature) are detected, hydrogen concentration Ch in a mixing exhaust gas is calculated based on the detected ethanol concentration Cetha and the detected cooling water temperature (or the detected intake air temperature) amplitude gain β corresponding to the calculated hydrogen concentration is calculated and finally, an amplitude amount (α×β) of the upstream target air-fuel ratio is calculated.

A speaker apparatus in accordance with the present invention is for use with a vehicle having a compartment and is to be mounted to the vehicle. The speaker apparatus includes: an interior member including a hole edge that defines an attachment hole; a speaker unit configured to be placed in the attachment hole, the speaker unit including a limiting member; and a speaker grille configured to be attached in the attachment hole from an inside of the compartment, the speaker grille including a claw-fixing portion that is bendable and is configured to be engaged with the hole edge. Accompanying the engagement of the claw-fixing portion with the hole edge, the speaker grille is fixed to the interior member. Accompanying the placement of the speaker unit in the attachment hole, the limiting member is positioned in a bending space for the claw-fixing portion and thereby prevents disengagement of the claw-fixing portion from the hole edge.

A semiconductor device for power control includes a substrate made of aluminum. Lands of copper are formed on the substrate. Semiconductor chips, such as FETs, are mounted on the lands. The semiconductor chips are joined with the lands only through solder layers. A synthetic resin, which includes epoxide, covers the lands, the solder layers and the semiconductor chips on the substrate. Preferably, a coefficient of expansion of the synthetic resin is generally less than a coefficient of expansion of the substrate or a coefficient of expansion of the lands. Each semiconductor chip defines at least two corners positioned generally opposite to each other. Each land defines at least two corners disposed in proximity to the corners of the semiconductor chip. The corners of the land generally confine the corners of the semiconductor chip therein.
摘要:
A four-degree-of-freedom parallel robot capable of displacing a traveling plate with four degrees of freedom at a high speed and a high acceleration and positioning the traveling plate with high rigidity and high precision. The four-degree-of-freedom parallel robot has four actuators fixed to a base, four parallel linkages each of which is coupled at its upper end to a tip end of an arm of each of the actuators through a kinematic element such as a universal joint, and a traveling plate whose four corners are coupled to lower ends of the parallel linkages through kinematic elements. By controlling the actuators, a main member of the traveling plate is displaced with four degrees of freedom, i.e., translated in all directions and rotated around a predetermined axis. Only axial forces are applied to rods constituting the parallel linkages. Thus, the traveling plate can be positioned at a high speed and with high rigidity as well as high precision.
