摘要:
There is disclosed an aluminum or aluminum alloy extruding die, which comprises Co-group alloy, Ni-group alloy, Cr-group alloy or like high temperature wear-resistant alloy coating applied by thermal spraying on a required die surface portion having been formed in the shape of a rough surface having surface roughness Rz of 5 &mgr;m or more. Preferably, after application of the alloy coating, the die is held at a temperature in the range from 500 to 800° C. for a predetermined period of time or the alloy coating surface is so roughened as to have surface roughness Rz of 10 &mgr;m or less.

A toilet covering hinge assembly has a damping capability for damping the motion of the toilet covering from a raised to a lowered position upon a toilet. The assembly includes a hinge shaft connecting the toilet covering to the rear of the toilet so as to be rotatable together with the toilet covering between the lowered and raised positions. Also connected to the hinge shaft is a dashpot which is secured on the side of the toilet and comprises a cylinder containing a volume of damper fluid and a rotor rotatably received within the cylinder. The rotor receives the hinge shaft to be rotatable together therewith and is provided with a flap extending outwardly into the damper fluid. The flap is pivotable relative to the rotor such that the flap is caused to, in response to the toilet covering moving from the lowered to the raised position, pivot into a folded condition where it receives no substantial resistance from the damper fluid and is caused. In response to the toilet covering moving from the raised to the lowered position, the flap pivots into an unfolded condition where it receives increased resistance from the damper fluid for dampening the motion of the toilet covering moving in that direction. The flap is formed to have an integral anchor bulb which is rotatably fitted within a corresponding bearing cavity in the outer surface of the rotor so that the flap is pivotally supported to the rotor without requiring any other supporting structure.

An automatic faucet apparatus comprises a drive control means wherein an intermediate drive section coupled to a motor as normally resiliently biased toward the original position is interlocked to a driving shaft coupled to a valve member with a play involved in the interlocking, so that, when the motor is energized to provide an actuating torque to the intermediate drive section and is thereafter deenergized, the intermediate drive section can reset to the original position without requiring any motor output, while the driving shaft is prevented from being affected by the resetting of the intermediate drive section due to the play involved.
摘要:
A method of determining at least one dimension of an extrusion die includes determining a plurality of reference points on a contour of an opening of the extrusion die. Sizes of a plurality of figures with same shapes corresponding to the plurality of reference points are determined. Each of the plurality of figures is inscribed in the contour of the opening and has at least one axis of symmetry. Each of the plurality of figures contacts each of the plurality of reference points and at least one another point on the contour. The at least one dimension of the extrusion die is determined based on the sizes of the plurality of figures.
