Title: Differential limiting device for car
Inventor: KOBAYASHI TOSHIO
IPC: F16H48/38
Filed: 1989-03-31
Abstract: PURPOSE:To enhance the control accuracy for the working oil pressure to be fed to a wet type hydraulic multi-disc clutch by equipping it with a balance oil pressure chamber, which is to cancel the centrifugal oil pressure applied to the oil pressure chamber of piston. CONSTITUTION:A wet type hydraulic multi-disc clutch 19 is interposed between a differential case 9a of an independent differential device and side gears 9d, 9e, and the working oil pressure is controlled according to the running condition and road surface condition for accomplishing power transmission to the left and right drive wheels at any desired proportion. The working oil and lubricant are supplied from an oil sump 6c via a hydraulic control device 23, so that a proper oil can be used and no stick-slip will be involved even though a large angle steering has generated a rotation difference between the left and right wheels. Thus smooth slip action is obtained. Further a balance oil pressure chamber 19i is furnished to cancel the centrifugal oil pressure applied to a piston 19g during the differential case 9a being in rotation, that will provide accurate control of the working oil pressure and enhanced the control accuracy.

IPC: H04N1/04
Filed: 1986-04-11
Abstract: PURPOSE:To compensate the chromatic aberration that an optical system by varying the thickness or refractive index of a color filter according to the difference in wavelength of light passed through each filter. CONSTITUTION:When spot light source of magenta and a spot light source of red are arranged at the same position distant from the axis of a single lens 1, their images are formed at different position Fv and FR. When a body A is vertically viewed through a parallel plane plate 6, on the other hand, its apparent position is A', but the quantity AA' of flotation varies with the thickness and refractive index of the parallel plane plate. Therefore, when a spot light source of, for example, white is image-formed through parallel plane plate filters of the three primary colors R, G, and B, there is a shift in the image formation position owing to the chromatic aberration on condition that the three kinds of filters are equal in thickness and refractive index, but the image formation position is made coincident by selecting the thicknesses or refractive indexes of the filters so that the aberrations and the quantities of flotation cancel each other.
