The Electronic Module includes body casethat comprises a plurality of case membersby abutting each other and that has an internal space (S) where the first opening Pis formed on one side surface of the internal space (S) and the second opening Pthat opens in a direction different from that of the first opening Pis in an exposed state when a plurality of the case membersare separated each other, a substrateon which a sensor ICis mounted and that is housed in the internal space (S) of the body case, and a resin bodythat covers the substrateby being filled in the internal space (S) of the body caseand solidified or hardened, and is characterized by that a plurality of the case members

Electronic module and method for manufacturing electronic module

The Electronic Module has a body case, including a plurality of case membersand that has an internal space (S) where a first opening Pis formed on one side surface of the internal space and a second opening Pthat opens in a direction different from that of the first opening Pis in an exposed state when a plurality of the case members are separated each other, a substrateon which a sensor ICis mounted and that is housed in the internal space of the body case, and a resin bodythat covers the substrateby being filled in the internal space of the body case and solidified or hardened, and is characterized by that a plurality of the case members and the substrateare integrated by the use of the resin bodyas an accouplement.

An A/D conversion device includes a first A/D converter that receives an analog vibration signal corresponding to a vibration detected by a vibration detecting sensor and converts the analog vibration signal to a first digital value, an analog amplifier that amplifies the analog vibration signal and outputs an amplified signal, a second A/D converter that converts the amplified signal to a second digital value, a determiner that determines whether an amplitude of the amplified signal input to the second A/D converter exceeds a range of amplitude that is convertible by the second A/D converter, and a selector that receives the first digital value and the second digital value and output one of the first and second digital values based on the determination of the determiner.

A/D conversion device and vibration damping apparatus for automobile using the A/D conversion device

The present invention provides a vibration damping device which can enhance a vibration damping effect even in a case where a vibration damping target position and a vibration damping force generation position are different from each other. The vibration damping device includes a vibration detecting unit for detecting a vibration which is caused by a vibration generating source and is transmitted to a position at which the vibration is to be damped; a vibration application unit which generates a vibration damping force to cancel the vibration, and is provided at a position different from the position at which the vibration is to be damped; a vibration application command generating unit for outputting a vibration application command to generate the vibration damping force in the vibration application unit, based on the vibration detected by the vibration detecting unit; and a vibration application command correcting unit which imparts to the vibration application command, a reverse property of a vibration damping force transmission path including a vibration transmission property from a position at which the vibration application unit is mounted to the position at which the vibration is to be damped, and then outputs the vibration application command to the vibration application unit.
