摘要： A gasket for arrangement between a cylinder block and cylinder head of an internal combustion engine. The gasket includes a lubricant hole through which lubricant is supplied to the cylinder head. A high pressure bead extends around the lubricant hole. A low pressure bead is extends around the high pressure bead and at least partially extends around a hollow portion, which is in communication with a lubricant reservoir of the engine, when the gasket is arranged between the cylinder block and the cylinder head.

摘要： A motor control device that has a high-frequency component, and a DC bias component that has a magnitude which causes a motor to be magnetically saturated and take on a certain value over a predetermined period, and is positively and negatively symmetrical are impressed as an observation command on a d-axis current command. The polarity of the magnetic pole of a permanent magnet is identified based on a relationship of large and small magnitudes between a first amplitude, which is attained during a period during which a DC bias component takes on a positive certain value, among amplitudes of a high- frequency component contained in a d-axis response voltage computed based on a feedback current respondent to the observation command, and a second amplitude attained during a period during which the DC bias component takes on a negative certain value.

摘要： Provided is a current detector that, even when the skin effect occurs in a conductor in which a current flows, can detect the current flowing in the conductor with high accuracy. A sensor part that is provided near a conductor and detects magnetic flux in a predetermined magnetic flux detection direction, a current detection part that detects a current flowing in the conductor based on a detection value of the sensor part, a current frequency acquisition part that acquires a current frequency as a frequency of the current flowing in the conductor, and a correction part that corrects the detection value of the sensor part based on the current frequency are provided.
