Abstract: A robust vibration damping device not suffering from destruction even when an earthquake force is increased. A vibration damping wall structure includes a structural frame comprising a foundation, a beam, and vertical members. One set of vibration damping devices are attached to a first vertical member, and another set of vibration damping devices are attached at positions respectively opposing the one set of vibration damping devices to a second vertical member. Each of the vibration damping devices is connected with the vertical member by way of a brace. The vibration damping devices in the one set and opposing vibration damping devices in another set are connected each other in a lateral direction by lateral connection members between each of the sets. Further, the vibration damping devices of each of the sets are connected each other in a vertical direction by the vertical connection members respectively in each of the sets.

Abstract: A vehicular headlamp having an inclination measuring unit mounted on portions of an aiming screw which extends rearward from reference member. The inclination measuring unit is interposed between a reference member and the rear end portion of the aiming screw, protruding rearward from the reference member.

Abstract: A headlight for a motor vehicle having a level for adjusting the direction of light emission from the headlight in the vertical direction in which the quantities of heat transmitted to the respective regions of the casing of the level which face the bubble vial of the level are made substantially equal to each other, even if the temperature around the level changes due to the lighting or extinction of the bulb of the headlight or the like, so that the accuracy of the measurement performed with the level is maintained despite changes in the temperature around the level.

Abstract: Disclosed herein is a headlight of double beam type, which comprises a lamp body having one end closed and the other end open; means defining in a given part of the closed end of the lamp body an aperture; a lens covering the open end of the lamp body; an upper beam projecting unit including a first concave light reflective integrally formed on a part of an inner surface of the closed end of the lamp body, and a first light source installed at a center portion of the first concave light reflector; and a lower beam projecting unit including a condensing lens installed in the lamp body at a position facing the aperture, a second concave light reflector detachably connected to the outside of the lamp body in a manner to face the aperture, and a second light source installed at a center portion of the second concave light reflector.

Abstract: A lamp assembly capable of functioning both as a fog lamp and a cornering lamp on a motor vehicle, comprising a fixed reflector within a housing, a movable reflector positioned forwardly of the fixed reflector, and a light bulb mounted to the fixed reflector and extending forwardly therefrom through an aperture in the movable reflector. The fixed reflector reflects the light rays from the bulb in the forward direction of the lamp assembly. Considerably less in size then the fixed reflector, the movable reflector pivots about a vertical axis between a first position, where it coacts with the fixed reflector to reflect the light rays forwardly in the use of the lamp assembly as fog lamp, and a second position where the movable reflector deflects part of the light rays toward one side of the lamp assembly to enable the same to server as cornering lamp.

Less in size then the fixed reflector, the movable reflector pivots about a vertical axis between a first position, where it coacts with the fixed reflector to reflect the light rays forwardly in the use of the lamp assembly as fog lamp, and a second position where the movable reflector deflects part of the light rays toward one side of the lamp assembly to enable the same to serve as cornering lamp.

Abstract: A lamp assembly integrally comprising the functions of a fog lamp and a cornering lamp on a motor vehicle. Included are an electric bulb or like light source immovably mounted within a lamp housing, a fixed reflector behind the light source, and a movable reflector between the light source and the fixed reflector. The fixed reflector reflects the light rays from the source in the forward direction of the lamp assembly. Considerably less in size than the fixed reflector, the movable reflector is pivotable between a first position, where it coacts with the fixed reflector to reflect the light rays from the source forwardly as when the lamp assembly is being used as a fog lamp, and a second position where the movable reflector deflects part of the light rays from the source toward one side of the lamp assembly as when the lamp assembly is desired to serve the additional function of a cornering lamp.

Abstract: A vehicular lamp assembly such as a combined fog and cornering lamp has a lamp cover mounted to its housing for pivotal movement between an open position, where the lamp cover uncovers the front lens of the lamp housing, and a closed position where the lamp cover covers the front lens. For pivoting the lamp cover between the open and closed positions a lamp cover drive mechanism comprises a drive shaft protruding from the lamp housing and coupled directly to the lamp cover. The drive shaft is driven by a reversible electric drive motor via a torque limiter which permits the motor to rotate independently of the drive shaft upon jamming of the lamp cover, as by being clogged with snow. Also included is an electric control circuit which controls the drive motor for opening and closing the lamp cover in response to the actuation and deactuation of a hand switch within easy reach of the vehicle driver. The control circuit further turns on the light source of the lamp assembly only when the lamp cover is opened.
