There are provided screw segments 100, 200 that are capable of shearing and kneading feedstock without causing plugs within a cylinder 1 of a screw extruder, and of extruding it from the cylinder 1. The screw segments 100, 200 each comprise a shaft part 111 to be affixed to a screw shaft 7, and a tooth part 112 that protrudes radially outward from the shaft part 111. The tooth part 112 comprises a tooth surface 116 that is formed on the front side relative to the rotation direction of the screw shaft 7, and that is so sloped as to transition gradually forward relative to the rotation direction as it transitions radially outward from the shaft part 111.

A battery including an outer casing, positive and negative electrodes provided in the outer casing, and an electrolyte provided therebetween. The outer casing is electrically connected to one of the positive and negative electrodes to constitute one of electrode terminals. The other is connected to the other electrode terminal which is electrically insulated from the outer casing. At least one of the positive and negative electrodes and the electrode terminal are connected to each other through a collector, which includes a plate-shaped body section and a connecting piece extended in an almost vertical direction from an end of the body section. The body section or the connecting piece is provided with a bending guide section which can be bent in such a direction that the connecting piece approaches the body section.

A rectangular battery having an electrode group which is inserted in a battery case having an airtight structure. The electrode group is formed by alternately stacking positive electrodes and negative electrodes via separators. The battery case is rectangular had has a closed bottom and an open part that is airtightly sealed by a cover. The outermost electrodes, which are located on both faces of the electrode group, are coated with an active material on a surface of a core. Furthermore, the outermost electrodes have the same polarity and the cores thereof directly contact an inside surface of the outer battery case. In one embodiment, the capacity of the outermost electrodes is smaller than the capacity of the inwardly disposed electrodes of the same polarity.

A sealed rectangular battery has a conductive battery case including an external casing and a sealing cap. The external casing encloses a generator element and is sealed by attaching the sealing cap using heat. The battery includes an electrode terminal with an opposite polarity to the battery case, and a safety valve. The safety valve includes a cap that is charged with the same polarity as the battery case and a valving element that covers a vent hole. The electrode terminal and safety valve are provided separately at different positions on the battery case. This construction is simpler than conventional batteries where the safety valve is integrally formed with an electrode terminal, which means that the electrode terminal can be miniaturized. This battery also has improved internal resistance.
