Abstract: A method includes a step A of ultrasonic-joining stacked metal foils to each other and a step B of ultrasonic-joining all of the joined metal foils and a metal plate to each other after the step A. The step A is performed by transmitting ultrasonic vibrations to a horn with the stacked metal foils being interposed between the horn and an anvil and pressed. The step A includes a first joining step of solid-state-joining at least some metal foils of the stacked metal foils that are located near the horn to each other, and a second joining step of solid-state-joining all of the stacked metal foils to each other after the first joining step. The second joining step is performed within a joined region that is joined at the first joining step.

Abstract: An electric storage device includes an electrode body including a plurality of first electrode plates and a plurality of second electrode plates, a first electrode output terminal, a second electrode output terminal, a first current collector, and a second current collector. The first electrode plates have first tabs that protrude from the electrode body and have conductivity and are connected to the first current collector. The first tabs are stacked to form a first tab stack, one surface of the first tab stack is in contact with the first current collector, and a first protective sheet is disposed on and in contact with the other surface on the side opposite to the one surface. On the periphery of the first protective sheet, there is a corner formed by two adjacent sides. At least the corner of the first protective sheet is joined to the first tab stack.

Abstract: An apparatus for detecting people waiting for an elevator. A detecting unit detects the number of people waiting on the basis of an image from an image pickup unit and delivers that number to a corresponding second people waiting detecting unit. The apparatus includes a unit which generates a coefficient depending on a percentage of overlap of the field of view of a reference image pickup unit, which is one of several image pickup units, with the field of view of a different image pickup unit on the basis of data on the allocation of an elevator, and calculates the number of waiting people in the overall hall from the respective numbers of waiting people output from the plurality of image pickup units and those coefficients. The coefficient generating unit generates a maximum coefficient for the reference image pickup unit and a smaller coefficient for any remaining image pickup unit based on the of overlap of the field of view of the respective image pickup units.

Abstract: An elevator control system for controlling movement of cages up and down in accordance with the situation of waiting persons in landing places or passengers in the cages detected by image pickup devices and other detecting devices includes first and second image processors, the image processing level of the second image processor being not lower than that of the first image processor. The system further includes an elevator controller for controlling movement of the cages up and down, the elevator controller including a device for applying the result of image processing performed by the first image processor to the control of the cages, and a device for applying the result of image processing performed by the second image processor to the control of the cages when the image processing is carried out based on the result of image processing performed by the first image processor and other information pertaining to passengers and waiting persons detected by the other detecting devices.

Abstract: An image of an elevator hall or an inside of elevator car is acquired by photographing apparatus, and the number of waiting passenger is detected by comparing the above-mentioned image with a background image when no passenger is present at the elevator hall. Second image processing apparatus with high precision is prepared by the same image information as that of first image processing apparatus, teacher information derived therefrom is compared with an output from the first image processing apparatus. If the teacher information is not coincident with the output from the first image processing means, parameters required for performing the image process by the first image processing appartus, for instance, constants, threshold values and weight coefficients employed in an image processing algorithm are adjusted.
