Title: Bearing device
Inventor: SASAKI KATSUHIKO
IPC: F16C27/06
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To prevent the transfer of vibration to a main machine by arranging an elastic body between the outer ring of a bearing and the bearing storage section of a housing storing it, and holding the bearing with a bearing cover which brings the bearing into contact with the outer ring and is fixed to the housing via the elastic body. SOLUTION: A bearing cover 10 holding a bearing 4 in a gear housing 8 is elastically fixed to the gear housing 8 by an elastic rubber washer 12, and elasticity is applied to the disk-like bearing cover 10 itself. The axial movement (deflection) of the bearing 4 is little regulated by the bearing cover 10, and the vibration caused by the rotation of an armature is sufficiently absorbed by an O-ring 9 between a bearing outer ring 4b and a bearing storage section 8a and the rubber washer 12 between the bearing cover 10 and the gear housing 8, thereby the transfer of vibration to a main machine can be surely prevented.

Title: Image pickup element and driving method of the same
Inventor: NISHIMURA RYUSHI
IPC: H04N5/335
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To provide an image pickup element generating the moving image and the still image of high image quality by setting the prescribed number of image elements, thinning the number of image elements at equal intervals, transferring them to a vertical transfer means and transferring/outputting transferred image element signals in a horizontal direction. SOLUTION: An image element signal is read to a vertical transfer part 12 during a vertical part blanking period. The vertical transfer part 12 sequentially transfers the image element signals to a vertical direction in a horizontal blanking period. A horizontal transfer part 13 sequentially outputs the image element signals for one line, which are transferred from the vertical transfer part 12, from an output terminal 15 through an output amplifier 14 in a horizontal scanning period. The color filter array of image pickup elements is set in the vertical stripe form of three primary colors RGB. In the case of a vertical stripe filter, the thinning/reading of the equal intervals can be executed. Thus, video signals fitted to the generation of a moving image and a still image different in resolution can be outputted and the image elements are thinned at the equal intervals. Thus, the image of high image quality with less folding noise can be obtained.

Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To increase the strength in the longitudinal direction of a film, and also, increase the rupture ductility in the longitudinal direction by setting the film thickness at a specified value or lower, and setting the elastic modulus in the film longitudinal direction at a specified value or higher, and also, setting the product of the elastic modulus in the film longitudinal direction and the rupture elongation at a specified value or higher. SOLUTION: A completely amorphous undrawn film of which the major component is polyethylene terephthalate, is biaxially drawn, and this biaxial orientation polyester film is produced. In this case, the film thickness is set at 10 μm or lower, and the elastic modulus in the film longitudinal direction is set at 6.5 GPa or higher. In addition, the product G×L of the elastic modulus G in the film longitudinal direction and a rupture elongation L% is set to be 500 or higher. In order to produce a film of such a large elastic modulus, the drawing in the longitudinal direction is performed by dividing the drawing into a plurality of times, and the film is drawn to approx. 4.5 times or more in the longitudinal direction as a whole body.  By this constitution, when being used by making the film thinner in the longitudinally strengthened film, a stable process can be performed without a breakage or a plastic deformation in the film working process.
