Transformer

A transformer including a first magnetic core and a second magnetic core having the shape of a flat plate. In the first magnetic core, a middle leg and substantially L-shaped outer legs whose inner sides are formed as circular-arc-shaped surfaces are provided in a standing manner at the central portion and at the comers of a rectangular flat plate, respectively. In addition, in the first magnetic core, a winding accommodating portion is formed between the circular-arc-shaped surfaces of the corresponding outer legs and an outer peripheral surface of the middle leg. Three coil portions, formed by spiral winding operations in level states, are placed upon each other, and are inserted into the winding accommodating portion of the first magnetic core. Then, from above the coil portions, the second magnetic core is placed thereon in order to form an integral structure. At this time, at the side portions of the flat plate, an external line of the flat plate and an external line of the winding accommodating portion coincide with each other. Therefore, the footprint of the transformer becomes small. Accordingly, in the invention, the transformer can be made smaller and thinner as a result of making the dead space that exists during the mounting of the coil to the magnetic core as small as possible.

Controller for internal combustion engine

The alcohol concentration detection value estimated or detected by the alcohol concentration sensor is corrected in accordance with intensity, frequency and the like of knocking to set the alcohol concentration detection value after the correction as the alcohol concentration for ignition timing control. Thereby, occurrence of the knocking can be prevented by changing ignition timing in accordance with the knocking state. In regard to the fuel injection control, the alcohol concentration detection value before the correction is used as the alcohol concentration for fuel injection control as it is without using the alcohol concentration detection value corrected in accordance with the knocking state. This prevents a fluctuation of the fuel injection quantity due to correcting the alcohol concentration detection value in accordance with the knocking state, leading to prevention of a torque fluctuation or combustion deterioration.
