Abstract: A security mirror construction with a mirror panel which can only be replaced by one having generally authorized access to the mirror construction and where the mirror panel itself is generally isolated so that damage to the mirror panel by vandalism or otherwise is eliminated and where injury to a user in the event of a broken mirror panel can normally be avoided. The mirror construction is comprised of an outer housing having a base plate for supporting a mirror panel on the base plate and within the mirror housing. A bracket arrangement retains the mirror panel on the base plate and within a fixed position in the housing. A transparent cover panel, preferably formed of a shatter-proof material, such as plastic, extends over the mirror panel and is also held within the housing by another bracket arrangement. In this way, if a vandal attempts to damage the mirror construction, damage will normally occur to the exterior plastic panel.

Abstract: The reflection mirror of this invention is considered an improvement over the conventional art in that it has a plating means that smoothes the inner surface of the reflection mirror body and a means for intercepting the heat of the light and that the mirror can be assembled into a desired size. The feature of this improvement is that the simplified polishing work that smoothes the inner surface of the reflection mirror body does not degrade but rather improves the quality of the mirror, uniformity of illumination directivity, and productivity. Since the heat absorbing layer absorbs heat rays, any deterioration of an object being illuminated can be prevented. Another advantage is that it is possible to prevent loss of freshness of food, and discoloration and deformation of products that might otherwise be caused by heat rays.

Abstract: An actuator for tilting the plane of an object is constructed from a stack of piezoelectric or electrostrictive members. First alternate interstices between the members are filled with a first conductive material, except that a first gap remains between the material and one side of the stack. Similarly, second alternate interstices between the members are filled with a second conductive material, except that a second gap remains between the material and an opposite side of the stack. The first gap and the second gap have unequal depth into the stack. The first material in the first interstices is coupled in common and the second material in the second interstices is coupled in common. A voltage applied between the first material and the second material will thereby cause the stack to bend, thereby tilting the plane of the op of the stack.

Abstract: A uniformly flexible core, and method for manufacturing the same, for use between the face plates of a sandwich structure. The core is made of a plurality of thin corrugated strips, the corrugations being defined by a plurality of peaks and valleys connected to one another by a plurality of diagonal risers. The corrugated strips are orthogonally criss-crossed to form the core. The core is particualrly suitable for use with high accuracy spherically curved sandwich structures because undesirable stresses in the curved face plates are minimized due to the uniform flexibility characteristics of the core in both the X and Y directions. The core is self-venting because of the open geometry of the corrugations. The core can be made from any suitable composite, metal, or polymer. Thermal expansion problems in sandwich structures may be minimized by making the core from the same composite materials that are selected in the manufacture of the curved face plates because of their low coefficients of thermal expansion.
