  • Publication number: 20200136190
    Abstract: A mono-cell is formed of a separator, a positive electrode, a separator and a negative electrode bonded to one another. Each separator includes a ceramic layer facing the positive electrode. On a lower surface and an upper surface of the positive electrode, an adhesive is applied at points lined up on a straight line along a width direction orthogonal to a conveyance direction. When an application length is defined as the product of the number of application points of the adhesive lined up in the width direction and the application diameter of each adhesive, the number of application points and the application diameter are set such that a value obtained by dividing, by the application length, a force applied to each ceramic layer based on acceleration and the weight of the separator during suction and conveyance becomes smaller than the necessary peeling strength per unit length of the ceramic layer.

  • Patent number: 9907141
    Abstract: A luminance control device and a luminance control method for controlling luminance of a light emitting member are provided in order to reduce the amount of information to be stored while preventing the user from feeling uncomfortable. The CPU divides by the interpolation division number a value obtained subtracting the reference duty ratio from the reference duty ratio so as to calculate an interpolation variation width, and integrates the interpolation variation width to the reference duty ratio every time the interpolation period elapses, and the variation width in the luminance of the LED is therefore reduced, preventing users to feel uncomfortable, which allows for suppressing the amount of information to be stored.
