This invention relates to a can end (1) providing improved tab access for a consumer. A further aspect of the present invention relates to a container incorporating such a can end (1). The can end (1) includes a moveable portion (30) located beneath all or part of the handle (20b) of the can end, with the moveable portion deformable from an ‘up’ position (30a) to a ‘down’ position (30b) to provide increased tab access for a consumer. The can end (1) is provided with one or more downwardly inclined annular steps (31), which has been found to greatly increase the force required to deform the panel from the ‘down’ to the ‘up’ position, therefore resulting in a far greater likelihood of the consumer receiving a container (40) incorporating the can end (1) with the moveable portion (30) in the ‘down’ position (30b), thereby facilitating tab access.

A layered heat exchanger, for example for use for motor vehicle coolers. To provide a turn portion in the heat exchanger for changing flow direction of a fluid flowing zigzag through a fluid circuit, a metal plate is provided at the upper or lower ends of a partition ridge with a fluid flow direction changing passage forming caved portion having a bottom wall of circular-arc cross section. Front and rear upper or lower tank portions are held in communication with each other through a fluid flow direction changing passage of approximately circular cross section and formed by the caved portions opposed to each other. The turn portion is diminished in stress concentrated thereon due to fluid internal pressure and given an increased resistance to pressure to effectively prevent tank side walls from breaking, consequently making it possible to decrease the metal plates thicknesses, to achieve a cost reduction by the decreased thickness and to assure an improved heat exchange efficiency.

To provide a mechanical seal in which degradation or tearing of a bellows does not occur, the spring constant of the bellows is reduced, and the fluctuation in the load due to stretching and contracting of the bellows is reduced. An inside-type mechanical seal includes a sleeve fixed to a rotating shaft, and a cartridge fixed to a housing. A rotation-side sealing ring is provided to the sleeve. A fixed-side sealing ring, which slides against the rotation-side sealing ring, and a bellows for axially urging the fixed-side sealing ring is provided to the cartridge. The bellows is made from a metal; and the metal bellows has one end fixed to a case for holding the fixed-side sealing ring and another end fixed to the cartridge. The plate thickness of the metal bellows is set so as to be smaller than the plate thickness of the case or the cartridge.

The invention discloses a specially-shaped extruding female die of an aluminium alloy seamless gas cylinder, which comprises a bottom plate, an edge pressing ring, a specially-shaped backward extruding female die, an ejection block, a quenching hard plate and an ejection rod, wherein the specially-shaped backward extruding female die is in fit with the ejection block arranged on the bottom of the specially-shaped backward extruding female die to form a specially-shaped backward extruding female die semi-closed cavity, of which the bottom is a stepped variable section and which is provided with a sloped outline circumferentially; the quenching hard plate is arranged on the bottom plate; the combined ejection block and the specially-shaped backward extruding female die are placed on the quenching hard plate and connected to the bottom plate fixedly through the edge pressing ring and an edge pressing bolt sleeved on the specially-shaped backward extruding female die; and the ejection rod passes through the bottom plate and the quenching hard plate sequentially and is connected to the ejection block to form the specially-shaped backward extruding die of the aluminium alloy seamless gas cylinder. In the forming process of backward extrusion drawing of the gas cylinder, by the unique structural design of the specially-shaped extruding female die of the aluminium alloy seamless gas cylinder, the thickness of the metal of a sharp angle part at an edge of the bottom is reduced, the volume of the metal flowing to the centre of the bottom is reduced, the defect that the centre of the bottom of a cup body of the gas cylinder protrudes is solved, the process of subsequent processing of a protrusion on the bottom is cancelled, and the processing cost of a product is reduced.

A gap is provided at joining faces of a pair of metal works with an uneven shape when the metal works contact one another for joining. An adhesive agent having a chain-reacting curing reaction function is disposed within the gap. The adhesive agent is cured by an autogenously-generated curing reaction heat caused by an outer energy and an additional heat that is successively generated by the autogenously-generated curing reaction heat within the adhesive agent. A welding portion, where the works contact one another substantially directly, is welded by a laser beam, and the above-described energy for causing the autogenously-generated curing reaction heat for the adhesive agent is provided by the laser beam. Accordingly, a joining structure and method of metal works that can have less limitation in a joining location is provided.

A tooling system has means for applying a vacuum to hold the fastener at the working end of the tool. A cavity in a hollow pusher pin has lateral ports for exclusively providing a airway between the vacuum source and the fastener. In other embodiments of the invention the pusher pin has fastener-gripping jaws in the form of balls moveable within lateral passageways in the pusher pin open into the cavity. The balls are biased inwardly against the fastener by an outer elastic band on the tool body which encircles the pusher pin. When adapted for installing magnetic-release type fasteners, the bottom end of the pusher pin is of reduced diameter for insertion into a magnetic release fastener. The fastener-receiving panel is supported by an anvil having a magnet whereby the fastener is released from the pusher pin as the fastener is pressed into the panel.
