摘要:
A battery body, which is composed of a laminated body obtained by laminating a cathode and an anode via a separator or a wound body obtained by winding them in a laminated structure and a plurality of leads connected to the cathode and the anode, is contained in a flexible package, and after an electrolyte solution is injected thereinto, an opening of the package is sealed at pressure which is lower than atmospheric pressure and is reduced to not less than vapor pressure of the electrolyte solution so that a thin battery is fabricated. A rise in pressure in the battery due to generation of gas in the battery and volume expansion of the gas can be restrained when the battery is maintained at high temperature.

The invention provides a coil member of rotating electrical machinery, by which improvements in the mass production and downsizing thereof are enabled, which is a coil assembly for rotating electrical machinery, consisting of a plurality of coil combinations mounted at iron core slots, wherein the respective coil combinations 14 are inserted into slots at pitches equivalent to an appointed number of slots, and are formed of an integral coil member 21 in which the first and the second linear portions 21A and 21B alternately disposed at the inner layer side and the outer layer side in the slots, and the first and the second turning portions 21C and 21D for connecting the first and second linear portions 21A and 21B adjacent to each other outward of one end side and outward of the other end side in the lengthwise direction of the slots are integrated together. And, the first linear portion 21A of the appointed coil member 211 thereof, and the second linear portion 21B of another coil member 211 are laminated and disposed in the same slots.

A conveyor truck including a truck body and a plurality of rotary members rotatably mounted on the truck body in a plane parallel to the floor. A pair of drive wheels, rotatable by aligned rotary shafts lying in a plane parallel to the floor, are mounted on each rotary member. The rotation of each drive wheel can be independently controlled. Supports are mounted on the respective rotary members and are arranged generally perpendicular to the rotary shafts of the drive wheels. The supports support the drive wheels so as to rotate about the center axes of the respective rotary members and parallel to the floor, whereby the conveyor truck can smoothly move in any direction without reorientation of the truck body.

A battery package including laminate sheets adhered each other along their peripheral to form a container portion for receiving an electrode assembly and a seal portion. The seal portion surrounds the container portion and protrudes outwardly from side faces of the container portion. The seal portion has enough width to maintain the container portion free from moisture for long periods of time. The laminate sheets include a heat-adhesive polymer layer and a metal layer which stops moisture and provides a shape-maintaining ability to the laminar sheets. The seal portion is folded or curled to reduce a projection area of the battery package.
