| Number | Title | Issue Date |
| 4139772 | Plasma discharge ion source An ion source is described in which a compound of the material of a desired ion is dissociated in a plasma discharge process to provide a beam of charged particles including the desired ions. The proportion of the desired ion in the particle beam is selec... | 02/13/1979 |
| 4037454 | Tube forming An unpierced metallic billet of relatively large diameter is subjected to three successive stages of deformation so as to form a metallic tube of relatively small outer diameter. In a first stage, the billet is given a generally "C"-shaped cross-sectional... | 07/26/1977 |
| 3982816 | Method for measuring the parameters of optical fibers Parameters of a clad optical fiber are measured by irradiating the fiber with a laser beam to generate a scattering pattern. Measurements are made of fringes and modulations in the scattering pattern and these measurements are translated into such paramet... | 09/28/1976 |
| 3977926 | Methods for treating articles To eliminate the manual handling of individual articles associated with loading and unloading conventional treating apparatus, a plurality of articles are simultaneously treated in the carriers which are used for batch handling prior to and subsequent to ... | 08/31/1976 |
| 3970471 | Methods and apparatus for treating wafer-like articles Wafer-like articles are inserted through an input port into one of a plurality of slots in a rotatable disc having a slotted periphery. The disc is disposed in a vertical plane between a pair of closely-spaced parallel plates which laterally retain the ar... | 07/20/1976 |
| 3963489 | Method of precisely aligning pattern-defining masks A method of precisely aligning a pattern on one side of an opaque substrate with a pattern on the opposite side thereof through the use of pattern-defining masks, wherein at least certain pattern areas previously not formed on the substrate, as defined se... | 06/15/1976 |
| 3942107 | Method and apparatus employing thin conductive films on flexible nonconductive sheets for non-destructive measurement of electrical characteristics In a non-destructive, production-oriented technique for measuring an electrical characteristic of a material, a first nonconductive flexible sheet having a first conductive pattern thereon is pressed against a portion of the surface of the material, and a... | 03/02/1976 |
