A laser distance measuring apparatus, for measuring the distance between objects existing in two directions at least as seen from the apparatus by using laser light, comprises two projectors for projecting laser beams along a specified projection axis toward each one of the objects, a photo detector for receiving reflected light of projection from each object, a distance measurement processor for measuring the distance from a reference point of the apparatus to each object on the basis of the reception signal to the projection by the photo detector, and a distance calculation processor for calculating the distance between the objects on the basis of the distance data measured by the distance measurement processor and the angle formed by two projection axes, in which the projection axis by one projector is variable in angle with respect to the other projector. Therefore, the distance between objects can be measured easily and at high precision by one distance measuring operation only.

A method and apparatus for manufacturing laminates are arranged for forming a laminate block by sequentially folding back continuous metal sheets,and,drawn through outlets,out of rolls,and,of the sheets wound on reels,and,, with synthetic resin sheet members,and interlayers,alternately interposed between the metal sheets, into multiple stages, and pressing the thus stacked laminate block while electrically heating the continuous metal sheets,and,in the laminate block, wherein the stacking is performed while keeping the continuous metal sheets,and,in tension between the outlets,of the reels,and,and each end edge of the laminate block

Method for manufacturing laminates

A method for manufacturing a laminate includes steps of forming a laminated combination of synthetic resin sheet material with a metal foil laminated each other, thermoforming under a pressure the laminated combination while supplying an electric current to the metal foil, and, after termination of the current supply, cooling thus obtained laminate while further applying a pressure, whereby the laminated combination can be uniformly heated into its core part to allow the laminate of uniform quality to be obtained, while shortening manufacturing lead time and minimizing surface roughness.

A power-assisted cart includes a wheeled platform for supporting a load thereon; driving wheels mounted on the wheeled platform for, when driven, moving the wheeled platform; a drive unit for driving the driving wheels; an operating unit which may be in the form of a handle mounted on the wheeled platform for receiving an external force applied thereto when the cart is desired to be moved; a force detector for detecting a magnitude and direction of the external force applied to the operating unit; and a control for generating to the drive unit an output substantially proportional to the external force detected by the force detector.
