According to one embodiment, a battery includes an external container, an electrode group, and a sealing plate. The electrode group includes a positive electrode and a negative electrode wound in a flat shape with an insulating layer interposed therebetween. Thicknesses Tof the positive and negative electrodes are each from 0.03 mm to 0.08 mm. A first direction is orthogonal to a winding axis direction of the electrode group. A second direction is parallel to the winding axis direction. The thicknesses Tof each electrode, a thickness Tof the electrode group in the third direction orthogonal to the first and second directions, and an innermost circumferential height Hof the electrode group in the first direction satisfy 0.02≤(T×T)/H≤0.04.

Battery and battery pack

A secondary battery according to an embodiment includes an exterior material including an opening portion and including a bottom, a wound electrode group housed in the exterior material in order for an insertion direction to be perpendicular to a winding axis, and a lid attached to the opening portion of the exterior material and including at least a plate-like member, a positive electrode terminal, and a negative electrode terminal. When a minimum distance between the lid and the wound electrode group is A, 0.5 mm&#x3c;A&#x3c;2.0 mm is satisfied.

Seal plate for rotary machine

A method for disassembling/assembling a gas turbine including a seal plate disposed on a first side of a rotor disc in an axial direction of the rotor disc, and a seal plate restraint part for restricting movement of the seal plate in a radial direction of the rotor disc. The method includes a seal-plate-restraint-state switching step of operating the seal plate restraint part from a second side in the axial direction via a clearance between a platform of a blade and a region of an outer peripheral surface of the rotor disc except a blade groove for receiving the blade to switch between a seal plate non-restraint state where the seal plate restraint part does not restrict movement of the seal plate in the radial direction and a seal plate restraint state where at least a part of the seal plate restraint part protrudes in the axial direction.

Method for disassembling/assembling gas turbine, gas turbine rotor, and gas turbine

A method for disassembling/assembling a gas turbine including a seal plate disposed on a first side of a rotor disc in an axial direction of the rotor disc, and a seal plate restraint part for restricting movement of the seal plate relative to the rotor disc in a radial direction of the rotor disc includes a seal-plate-restraint-state switching step of moving the seal plate restraint part along the axial direction to switch between a seal plate non-restraint state where the seal plate restraint part does not restrict movement of the seal plate in the radial direction and a seal plate restraint state where at least a part of the seal plate restraint part protrudes in the axial direction from the seal plate and thereby restricts movement of the seal plate in the radial direction.

A method for disassembling/assembling a gas turbine including a seal plate disposed on a first side of a rotor disc in an axial direction of the rotor disc, and a seal plate restraint part for restricting movement of the seal plate relative to the rotor disc in a radial direction of the rotor disc includes a seal-plate-restraint-state switching step of operating the seal plate restraint part from a second side in the axial direction to switch between a seal plate non-restraint state where the seal plate restraint part does not restrict movement of the seal plate in the radial direction and a seal plate restraint state where at least a part of the seal plate restraint part protrudes toward the second side in the axial direction from the seal plate and thereby restricts movement of the seal plate in the radial direction.

According to one embodiment, a battery includes an electrode group, at least one positive electrode current collector tab, at least one negative electrode current collector tab, and a case. The case includes a case portion and an edge portion. The edge portion includes a heat sealed part configured to seal the case portion and a non-sealed part. The electrode group is housed in the case portion while an end portion of at least one of the positive electrode current collector tab and the negative electrode current collector tab is provided in the non-sealed part.

Battery

An intake system for an internal combustion engine includes an intake manifold adapted to be attached to a side wall of the engine, and an air cleaner for supplying intake air to the intake manifold. The air cleaner is disposed opposite to the side wall of the engine while interposing therebetween the intake manifold. The air cleaner has an air cleaner main body joined with the intake manifold to constitute a single unit. The air cleaner main body is made of a material lower in the strength than a material which the intake manifold is made of.

Intake system for an internal combustion engine

An intake arrangement for a multi-cylinder internal combustion engine of a vehicle which has a row of cylinders. The arrangement includes an intake manifold, which includes a collector extending along a direction of the row of the cylinders and a branch portion communicated with the collector, a fuel pipe extending along the collector, and a protector extending along the fuel pipe between the branch portion and the fuel pipe. The fuel pipe is disposed at a downstream end portion of the branch portion which allows air to be introduced into the cylinders. The protector is secured to the downstream end portion of the branch portion and deformable to cover the fuel pipe upon an impact load being applied to the branch portion.
