Abstract: A roll press apparatus includes a first press roll and a second press roll. The first press roll includes a first contact part configured to contact an active material portion of a strip-shaped electrode sheet and a second contact part configured to contact an active-material absent portion of the strip-shaped electrode sheet. The second contact part has a large frictional-force generating form that causes a larger frictional force to be generated between the second contact part and the active-material absent portion of the strip-shaped electrode sheet than an imaginary frictional force which would be generated if the active-material absent portion of the strip-shaped electrode sheet were made to contact the first contact part.

Abstract: A roll press apparatus forms a compressed strip-shaped electrode plate by roll-pressing a strip-shaped electrode plate including an active material portion and an active material absent portion and including a tensile-force-ratio adjustment mechanism adjusting a tensile force ratio of an upstream active material absent portion tensile force applied to an upstream side and a downstream active material absent portion tensile force applied to a downstream side of an inter-roll active material absent portion held in a non-compressed state between a pair of press rolls in an active material absent portion of the strip-shaped electrode plate.

Abstract: An electrically heated catalyst device includes a catalyst support supporting a catalyst, a surface electrode disposed on an outer surface of the catalyst support and extending in an axis direction of the catalyst support, a wiring line member including a root section extending in the axis direction of the catalyst support and comb teeth-like wiring lines extending from the root section in a circumferential direction of the catalyst support and fixed to the surface electrode, an outer cylinder covering an outer surface of the catalyst support, and a holding member holding the catalyst support and packed between the catalyst support and the outer cylinder, in which the catalyst support is heated by feeding a current through the surface electrode and the wiring line member. At least a plurality of through-holes or a plurality of protrusions are formed in the root section covered by the holding member.

Abstract: An electrically heated catalyst device is equipped with a carrier that supports a catalyst, a pair of electric diffusion layers that are formed opposite each other on an outer peripheral face of the carrier, wiring members that are fixed to the electric diffusion layers respectively, an outer cylinder that covers an outer peripheral face of the carrier and that has, in a lateral face thereof, an opening portion through which the wiring member is pulled out to the outside, and a wiring accommodation chamber that is provided protrusively from the outer cylinder to accommodate the wiring member pulled out from the outer cylinder. The carrier is electrically heated via the wiring member. The wiring accommodation chamber is equipped with a heat radiation suppression portion for suppressing the radiation of heat from the wiring member.
