  • Patent number: 4484884
    Abstract: A machine for high rate production of molecularly oriented thermoplastic bottles is disclosed. The machine is of the reheat-and-blow type. A blow molding station simultaneously blow molds article preforms arranged in matrices by modular article carriers for conveying the preforms and articles through the machine. The carriers are designed to retain the preforms throughout all operations of the machine from a preform load station through a thermal conditioning section, a blow molding station, and to a bottle eject station, thereby eliminating the need for other preform transferring apparatus. The article carriers together with the associated conveying apparatus comprise a sufficiently flexible structure that minor misalignments of the carriers with the blow molding mechanism do not adversely affect bottle production. Both loading of preforms and ejection of finished bottles are accomplished by operation upon matrices of preforms and bottles as defined by the carriers and conveyor lanes.

  • Patent number: 4485360
    Abstract: An rf load is matched to an rf source by a matching network having series and shunt impedances connected between the source and load. A network coupled to the load derives a first rf signal responsive to rf energy reflected from the load. Another network responsive to the first rf signal derives plural rf signals, each having an amplitude that is a different function of the magnitude and phase angle of the reflected energy. In response to the amplitudes of the plural rf signals, the values of the series and shunt impedances are controlled.

  • Patent number: 4483737
    Abstract: A method and apparatus for plasma etching a substrate, such as a semiconductor wafer, utilizing a multipole surface magnetic field confining within an etching chamber an etching plasma of substantially uniform density throughout its volume. The plasma is produced and maintained by subjecting a gas such as CF.sub.4 to an ionizing discharge within the chamber. Only DC power sources are used for the discharge, so that there is virtually no perturbing radio frequency interference produced. The wafer is consequently easily biased relative to the plasma for controlled fine-scale etching. Low gas pressures permitted by the surface magnetic field result in substantially anisotropic etching of the substrate by dense plasma concentrations.

  • Patent number: 4468746
    Abstract: The interval between first and second events, which may occur in a period less than a nanosecond interval, is determined with a square wave clock source started in response to the first event. The source derives a square wave having a first transition when started and equally spaced succeeding transitions spaced from each other by T/2, where T is the square wave period. A delay network having N taps is responsive to the square wave, whereby (N+1) square waves are derived. The taps are spaced from each other so the clock source square wave is delayed at tap k by kT/n, where n is a predetermined integer greater than 1 and k is selectively every integer from 1 to N. (N+1) memory elements respectively respond to the (N+1) square waves to generate a signal indicative of which half cycle of each of the (N+1) square wave is being derived when the second event occurs.

  • Patent number: 4457688
    Abstract: A blow molding machine is provided with an external center pin so that blowing is accomplished without introducing a mechanical or rigid member within the preform and/or bottle. To do this, the blowing is done by introducing a fluid, preferably a gas such as air, into the preform to expand it. Outside of the preform, meanwhile, is the subject center pin or center rod which is located on the preform center line (axis) and near the middle of the preform bottom. The rod receives a gate disposed centrally on the bottom of the preform when the preform is expanded by the entering fluid. In this manner, the center part of the bottom of the preform is engaged by the center pin which thereafter keeps the preform on center as the blowing action continues. A process is disclosed of blowing using a compressed fluid alone inside the preform to expand the preform axially against the bias of an external resiliently biased center pin.

  • Patent number: 4453221
    Abstract: A manipulator and control are provided for moving a function element carried by the manipulator in accordance with programmed input signals defining positions and path velocities therebetween of a tool centerpoint associated with the function element. The path velocity is made susceptible of variation in accordance with unprogrammed variations of a parameter manually or automatically produced. Motion of the tool centerpoint is effected by interpolation of intermediate point along a predetermined path between any two preprogrammed positions. Each intermediate point is displaced from its predecessor by an increment computed in accordance with a fixed increment interval period and an instantaneously variable increment velocity. Incremental velocity values are computed selectively in accordance with a simple function relating the variable parameter and velocity and in accordance with the preprogrammed definition of motion.
