    摘要: A connecting structure includes a circuit board with a first connection land having a plurality of conductor patterns on the surface thereof, a second connection land disposed in a position opposite to the first connection land of the circuit board, and a flexible board including an insulating layer formed so as to surround at least a part of outer periphery of the second connection land. The first connection land and the second connection land are bonded to each other with a bonding member, and the insulating layer is thicker than the total thickness of the second connection land and the first connection land. It is possible to obtain an electronic circuit connecting structure which is free from short-circuit due to running of the bonding member such as solder even with the connecting land greatly reduced in size, and its connecting method.

    摘要: A stationary position detection circuit and a motor drive circuit capable of more properly detecting the rotor position are disclosed. The stationary position detection circuit supplies an alternating current to each phase load of the motor. The time during which the current flows in a first direction and the time during which the current flows in a second direction opposite to the first direction are converted into electrical signals and amplified. In accordance with the value of the electrical signals, the position of the motor rotor in stationary mode is determined. The use of the alternating current, unlike the kickback voltage, makes it possible to improve the detection accuracy by amplifying the electrical signals with an increased number of alternations. An increased number of alternations can amplify the electrical signals without increasing the value of the alternating current, and therefore, unlike in the case of the kickback voltage, the alternating current of a large value is not required. As a result, the alternating current can be reduced to a small value and the vibration can be suppressed.
