摘要:
An anti-vibration device for a vehicle including a rod (11) fixed to an engine (1) at one end portion (12) thereof and fixed to a vehicle body at the other end portion (13) thereof, an inertia mass (15) supported on the rod (11), an actuator (17) operative to reciprocate the inertia mass in an axial direction of the rod, and an acceleration sensor (21) that detects vibration of the rod in the axial direction. The acceleration sensor (21) is disposed between the one end portion (12) of the rod (11) and the other end portion (13) of the rod (11). Accordingly, sensitivity to pitch vibration of the rod (11) is reduced so that accuracy in detection of rigid body resonance in the axial direction is enhanced.

A vibration absorption that is both capable of damping vibrations in two directions and high in durability. A pair of pressure receiving chambers (102A) and (102B) at symmetrical positions sandwiching an axis S are structured between a first rubber elastic body (24) and a second rubber elastic body (38). The shape of a first rubber elastic body (18) in an unloaded state is determined such that a region between an inner side joining portion (24B) and an outer side joining portion (24A) becomes substantially horizontal in a loaded state in which the first rubber elastic body (24) supports the weight of an engine.

Blackened layers 23A and 23B are formed by depositing Cu—Co alloy particles on the surfaces of a metal layer 21. The metal layer 21 coated with the blackened layers 23A and 23B of the Cu—Co alloy particles is subjected to a chromating process to form density-intensifying layers 25A and 25B on the blackened layers 23A and 23B. A base 11 is laminated to the density-intensifying layer 25A or 25B. A conductive structure 109 consisting of the meal layer 21, the blackened layers 23A and 23B, and the density-intensifying layers 25A and 25B is processed by a photolithographic process to complete an electromagnetic shielding sheet 1 having a mesh conductive structure.

A current driving device comprises: a voltage supply part; a current supply part; and a plurality of current output parts, each comprising a current-voltage converting function, a voltage-current converting function, and a voltage holding capacitance element. The current output part takes three operation modes. Under a voltage supply mode, the current output part receives a voltage from the voltage supply part and holds the voltage in the voltage holding capacitance element. Under a current supply mode, the current output part receives the current from the current supply part, generates a second voltage by the current-voltage converting function and holds the voltage in the voltage holding capacitance element. Under a current output part, the current output part outputs an output current according to the voltage held in the voltage holding capacitance element by the voltage-current converting function. By charging the current output part with the reference voltage before the calibration performed by using the reference current, calibration of the current output part is performed at a high speed.

The first voltage generating device generates the maximum voltage, and supplies the first set of voltages and the maximum voltage to the second voltage generating device. The second voltage generating device generates the minimum voltage, and supplies the second set of voltages and the minimum voltage to the first voltage generating device. The first and second voltage generating devices each select a voltage from the first and second sets of voltages, and output the selected voltage.
