Abstract: A damper arrangement for a glove box of an automotive vehicle is mounted separately from the glove box compartment in a space between other components mounted in an instrument panel of the vehicle. A pulley is mounted separate from both the glove box damper and the glove box compartment. A wire connects the glove box damper to a movable member associating the glove box compartment with a glove box lid via the pulley.

Abstract: A construction having a damping device for damping vibration having steel wire cables 20 having both ends fixed on the sides of the building 10, the steel wire cables 20 are tautly and obliquely provided on the building 10 so that one side and the other side of the steel wire cables 20 cross at only one point in front view. Since the steel wire cables 20 do not exist in the horizontal direction, the length of the steel wire cables 20 is shorter as compared with the prior art. Accordingly, extension of the steel wire cables 20 decreases, the mechanism is simpler, and maintenance is also simplified.

Abstract: A robot hand is implemented by a wrist mechanism coupled with a retaining member for allowing a work to rotate around a first axis, and the wrist mechanism comprises a first bracket member rotational around a second axis and a second bracket member holding the retaining member and rotational with respect to the first bracket member around a third axis, wherein the first to third axes cross at a virtual point within a virtual space occupied by the work so that a distance between the virtual point and a center of the work is decreased, thereby delicately controlling the attitude of the work.

Abstract: An in-focus detection apparatus used for a video camera includes edge width detector for detecting a plurality of edge widths of an object, and an calculation device for calculating the amount of driving a lens based on the distribution state of these plurality of edge width data. The apparatus uses a video signal and provides the in-focus state of an actual object with a high accuracy without requiring slight movement of a focusing lens.

Abstract: An automatic focusing apparatus according to the present invention comprises a photo-taking lens system, in which a focus has to be adjusted every time the focal length is changed, including at least a first lens unit for changing the focal length by means of its movement along an optical axis of the photo-taking lens during the zooming operation and a second lens unit for adjusting the focus by means of its movement along the optical axis, and a controller for controlling the speed of the second lens unit during the zooming operation based on the focal length of the photo-taking lens system, the lapse of the time related with focus detection cycles, the reliability of the result of the focus detection and so on.

Abstract: An automatic white balance adjusting apparatus having a light measuring circuit, a determining circuit, and adjusting circuit and a time-average calculating circuit, in operation, color temperature adjustment data are calculated by using a value obtained by averaging color temperature information of a light source over a predetermined time period.

Abstract: The present invention offers an apparatus which automatically aligns and packs fruits or vegetables like persimmons or tomatoes for example into containers. More particularly, the apparatus embodied by the invention is provided with means for conveying the delivered fruits or vegetables to a specific position below absorption unit following the location of fruits/vegetables feeding means, while the apparatus is also provided with absorbing unit moving between the vacuuming position of conveying means and the position for packing fruits or vegetables into a packing case placed at the packing position following the location of conveying means, and means for easily correcting the direction of fruits or vegetables as well as replacing rejected fruits or vegetables by allowing intervals to extend before and behind as well as between both side of a plurality of cups which make up conveying means at the direction-correcting position on the halfway of conveying route of conveying means.

Abstract: A hydrophilic corrosion-resistant coat is formed on the surface of a metallic material, e.g., aluminum and its alloys, by a method which comprises preparatorily cleaning the surface of the metallic material, applying on the cleaned surface of the metallic material an aqueous treating liquid produced by adding a water-soluble acrylic acid polymer and colloidal silica and effective amounts of a polyhydric alcohol and/or saccharide to an aqueous solution containing hexavalent chromium compound or trivalent and hexavalent chromium compounds, phosphoric acid, and a fluorine compound. The applied layer of the treating liquids is dried and baked, the baking being at a temperature in the range of 100.degree. to 250.degree. C.

Abstract: The invention is concerned with an improved construction of an apparatus for assorting such spherical fruitage as oranges, apples and pears by each different size thereof, comprising a plurality of assorting plates vertically overlapped with each other, the uppermost plate being provided with the largest diameter assorting hole and successive lower plates having holes of decreasing diameter so that as the plates progress in operation, the lower plates are successively moved downwardly into different positions, thereby permitting the fruits to be assorted free of any damage which otherwise might affect the rind of the fruits by passing the fruit through each of the assorting holes.
