Abstract: A white balance adjusting device includes a dichroic prism for dividing light reflected from an object into a green-component, a red-component and a blue-component. These primary color components are incident on a first CCD, a second CCD and a third CCD. Based on photometry data from a photometry sensor, an electronic charge accumulating period for the first CCD corresponding to the green-component is determined. Based on a colorimetry by a colorimetry sensor, electronic charge accumulating periods for the second CCD corresponding to the red-component and the third CCD corresponding to the blue-component are determined. When the color temperature is high, the electric charge accumulating period for the second CCD is set to be relatively long, and the electric charge accumulating period for the third CCD is set to be relatively short.

Abstract: In a still video device, a high definition image signal corresponding to one frame is passed through a low-pass filter with a cut-off frequency f.sub.ch, divided into "m" of parts, and stored in a memory at a sampling frequency f.sub.sh. The horizontal scanning frequency of the high definition image signal is f.sub.hh, and the horizontal effective period ratio of the high definition image signal is e.sub.hh. The image signal is read out from the memory at a sampling frequency f.sub.sn so that the image signal is time-expanded to be transformed to a normal image signal, which is passed through a low-pass filter with a cut-off frequency f.sub.cn. The horizontal scanning frequency of the normal image signal is f.sub.hn, and the horizontal effective period ratio of the normal image signal is e.sub.hn. The parameters satisfy the following relationships,f.sub.ch .multidot.K.ltoreq.f.sub.ch .multidot.(f.sub.sn /f.sub.sh).ltoreq.f.sub.cn .ltoreq.f.sub.sn /2 f.sub.cs .gtoreq.f.sub.cnwhereinK=(f.sub.hn /f.sub.hh).multidot.(e.sub.hh /e.sub.hn) .multidot.(1/m).

Abstract: An inclination adjusting device for an objective lens used for an optical information recording and reproduction apparatus with a reduced number of components for a small size and light weight is provided. An objective lens is held at an end portion of a plate spring. The other end portion of the plate spring is fixed to an adjusting board, which is supported in a manner so that it can tilt against a base on a spherical element as a support. The adjusting board is properly positioned with regard to the base by use of one guide pin. The adjusting board is tilted in the longitudinal direction of the plate spring and in the direction crossing the longitudinal direction by use of a first and second adjusting screws, respectively.

Abstract: The instrument panel is clamped at both longitudinal ends thereof onto an assembly jig mounted on a robot arm. The jig holding the panel is inserted widthwise into the car cabin through a door opening. The jig is moved to a preassembly position where the end walls of the panel overlap outer side surfaces of mounting brackets previously installed in the car cabin. The end walls of the panel are then fastened in place by nut runners provided at both ends of the assembly jig. The nut runners are mounted on tool holders which are able to perform a floating movement in a plane perpendicular to the car width direction. Positioning devices are provided at both ends of the jig to correct the position of the tool holders with respect to the brackets to align and position the panel so that the mounting holes in the end walls of the panel line up with the tapped holes in the brackets.
