摘要： A white balance correcting device for correcting white balance by using video signals is arranged to be capable of accurately obtaining white balance even in a case where a picture includes only a small white part therein. The white balance correcting device is arranged to divide a picture into a plurality of blocks, to obtain a mean value of signals by averaging signals of each divided block as representing the block and a peak value of luminance from a signal having the highest luminance among others in each divided block also as representing the block, and to use, for white balance control, either the mean value or the peak value according to the state of the object of shooting.

摘要： An exhaust passage has an upstream end connected to an engine combustion chamber and a downstream end open to the atmosphere. A device substantially equalizes natural frequencies of the exhaust passage respectively corresponding to third-degree and fourth-degree modes of standing pressure waves developing in the exhaust passage. A pressure damper is connected to a point of the exhaust passage at which an antinode of the third-degree or fourth-degree mode lies.

摘要： An engine mounting for suspending an engine relative to a vehicle structure. The engine mounting comprises a first armature for connection to the engine and a second armature for connection to the vehicle structure and a bellows interposed between the first and second armature to define therewith a closed enclosure. The closed enclosure is filled with pressuzied gas. An inertia mass is mounted on the bellows. A mass of the inertia mass and an apparent spring constant of the bellows are selected such that the inertia mass vibrates in inverse phase relationship with the phase of vibration of the first armature when the engine operates within a vibration insulated domain.
