摘要:
An active type magnetic bearing system includes magnetic bearings for suspending a rotary body to permit it to rotate about its rotational axis. A control system supplies the magnetic bearings with signals to control the radial position of the rotary body, and comprises displacement detecting circuits for detecting any displacement of the radial position of the rotary body and a control circuit for producing a control signal which serves to suppress any unstable vibration of the rotary body.

An active magnetic bearing apparatus wherein an object designed to be suspended is supported by a plurality of active magnetic bearings and is suspended in a non-contact state so that the object is caused to move in either a rotational or reciprocating manner in such a state. The magnetic force of the respective active magnetic bearings is controlled electrically. A delay control mechanism is provided to cause a delay in the starting-up time for the respective active magnetic bearings so that these bearings are caused to start up sequentially when they are activated, thus making it possible to make the capacity of the power source as small as possible.

An inductance-type displacement sensor which can measure the displacement of a measured object of magnetic material without any contact with the object. A pair of series connected coils is provided adjacent to the object so that the inductance of the coils varies in response to a displacement of the object from a predetermined position. The inductance, the number of windings, the direction of the windings and the section of each of the cores are so set that the magnetic flux produced by one of the coils runs in a direction opposite to that of the magnetic flux produced by the other coil and the densities of the respective magnetic fluxes are identical with each other.

A flywheel assembly has a base and a flywheel rotatable with respect to and in contact free relation with the base. First and second annular yokes are secured to the base coaxial with the flywheel, and coupled to each other by radially extending control poles. Control coils are wound around the poles. An annular magnet is mounted on the first yoke, coaxial therewith, and a third annular yoke is mounted on the magnet. An outer cylindrical yoke is secured to the flywheel at the outside of the first yoke, and an inner cylindrical yoke is fixed to the flywheel at the inside of the second yoke. The cylindrical yokes are coupled to each other by an annular yoke. A magnetic flux from the magnet flows through the magnet, third yoke, outer cylindrical yoke, first yoke, and the magnet, thereby controlling the axial position of the flywheel. A control flux produced by one of the coils flows through a control magnetic path which passes through one of the poles, first yoke, outer cylindrical yoke, annular yoke, inner cylindrical yoke, second yoke and said one of the poles, and extends radially with respect to the rotational axis of the flywheel, thereby controlling the radial position of the flywheel.

A spacer arranged inside a water jacket which is formed to surround peripheries of cylinder bores in a cylinder block of an internal combustion engine includes support legs extending in an up-and-down direction from a spacer main body part which partitions the water jacket into an upper and lower cooling water passages. The support legs are disposed in opposite end portions in a cylinder row line direction, where the temperatures of the cylinder bores tend to be lower. Accordingly, even if the flow of cooling water is more or less inhibited by the support legs and the cooling effect deteriorates, it is possible to prevent the temperatures of the respective cylinder bores from becoming different by suppressing the influence to a minimum.

An output compensating device capable of effectively correcting pixel signals composing an image taken and output by the image sensor having a wide dynamic range to be adaptively displayed with high quality and high contrast on a viewable screen area by using means for detecting a minimal value and a maximal value of sensor (pixel) signals output from the image sensor to be displayed on the screen area, means for offsetting the detected minimal value of the sensor signal to a lower limit value of the screen area and means for adjusting a gain of the sensor signal in such a way that an output width determined by the detected minimal and maximal values of the sensor signals may be equal to the maximal width or a specified width of the screen area.
