  • Patent number: 5513666
    Abstract: Oil quenched works are immersed in water at a temperature of 75.degree. C. while the works are maintained at a temperature of not lower than 100.degree. C. In the step of immersing the works in water, the water boils on the surfaces of the works to remove most quenching oil from the surface of the works. A part of oil removed from the works is caused to overflow from the upper portion of a water bath and exhausted therefrom. In the step of immersing the works in water, the works are retained at a temperature suited for an alkaline cleaner. After having been taken out of the water, the works are cleaned in a step of showering water. A step of immersing the works in the alkaline cleaner is performed before the temperature of the works becomes lower than 60.degree.C. The alkaline cleaner used in the step of immersing the works in the alkaline cleaner is maintained at a temperature of 70.degree. C..+-.5.degree. C. In this range of the temperature, quenching oil is continuously removed stably for a long time.

    Abstract: A raising and lowering mechanism is provided at a work station for vertically transferring articles or products delivered to the station by an overhead delivery conveyor. Discrimination between transfer of a load from the delivery conveyor and transfer back to the delivery conveyor is accomplished by a mechanical discriminator which appropriately conditions suspension hooks on the delivery conveyor for either releasing the load or reconnecting the load. The transfer mechanism employs a vertically reciprocating conveyor which is confined to a vertical transfer axis without the necessity to employ some degree of lateral movement to uncouple the load from the delivery conveyor, present the load at a working position within the work station, and return the load to the delivery conveyor. Drift compensation is provided to allow for some misalignment of a delivered load with the transfer axis.

  • Patent number: 5025280
    Abstract: A machine has been developed for photoresist processing which has two filtered upward flowing baths, one for the develop fluid and one for the rinse fluid. In order to be able to develop photoresist patterns with submicron geometries, it is necessary to retreat from the current method of developing on a conventional spin developer. The batch immersion develop would suffice in certain applications, but contamination and automation obstacles cannot be overcome with the batch immersion process. Also, the develop process cannot be accomplished on very small geometries which developing pattern side up due to ununiform developing across the wafer causing critical dimension sizing problems. The described concept utilized an upside down immersion process with automated in line capabilities. It requires a filtered bubble free, temperature controlled, slow upward flowing develop chemical which the wafer is immersed into while spinning very slowly.

Running parallel to the front side of the bench is a rail on which a robot rides, the robot supporting a hoist carriage which can be raised or lowered. Cantilevered from the carriage is a main arm articulated by an elbow shaft to a forearm that extends over the bench. The forearm is joined by a hand shaft depending therefrom to a hand that engages the handle of the work basket. A main arm motor acts to rotate the elbow shaft and thereby swing the forearm to a position generally aligning the basket with a selected tank therebelow.

  • Patent number: 4612946
    Abstract: An automatic set-up system is provided for setting up on a pallet work to be machined by a flexible manufacturing system automatic machine tool. The pallet has a support plate and a jig plate which overlies the support plate on which the work is placed. The support plate, the jig plate and the work are sequentially conveyed by a convey unit on a setting table. The relative positions of the support plate and the jig plate, and of the jig plate and the work are usually held constant by the engagement of positioning recesses and positioning pins. Even if the position of the jig plate or the work conveyed by the convey unit deviates from a predetermined position, a float base and a support plate (the float base, the support plate, and the jig plate) are floated by means of air bearing pads. The horizontal movement of these components can be readily controlled, so that positioning pins can be easily fitted in the positioning recesses.
