Patent number: 5446186Abstract: The synthesis and compound of a new caged calcium which is an ortho-nitrophenyl derivative of EGTA and various intermediates. It is synthesized in ten steps and 24% overall yield. The photosensitive chelator, nitrophenyl-EGTA, has a K.sub.d for Ca.sup.2+ of 80 nM and for Mg.sup.2+ of 8.8 mM. Upon exposure to ultra-violet light (in the region of 350 nm), the chelator is cleaved, yielding iminodiacetic acid photoproducts with known low Ca-affinity (K.sub.d =1 mM). The quantum yield of photolysis of nitrophenyl-EGTA in the presence of Ca.sup.a+ is 0.23 and in the absence of Ca.sup.2+ is 0.20. In experiments with chemically skinned skeletal muscle fibers, a fully relaxed fiber equilibrated with nitrophenyl-EGTA:Ca.sup.2+ complex, in the presence of physiological [Mg.sup.2+ ] (i.e. 1.0 mM), produced maximal contraction after a single flash from a frequency doubled ruby laser (347 nm). Half-maximal tension was achieved in 18 ms at 15.degree. C.Type: GrantFiled: November 9, 1993Date of Patent: August 29, 1995Inventors: Graham C. R. Ellis-Davies, Jack H. Kaplan

Patent number: 4859573Abstract: A process for selectively hardening a surface layer of a polymeric photoresist to make such surface layer opaque and insoluble in photoresist carrier solvents, where such selectivity is coextensive with the polymeric/monomeric pattern created in the photoresist. Representative hardening processes include controlled exposure to certain gas plasmas, ion bombardment, or irradiation by ultraviolet radiation of chosen wavelength range. The selectively hardened polymeric regions act as a barrier to the carrier solvent in which the polymer film is laid down and to the developer subsequently employed to remove the monomeric regions. The hardened polymeric regions further exhibit an actinic radiation barrier property preventing radiation depolymerization. In one form the process may be used in a two-layer photoresist structure, where the pinhole-covering thicker second layer is laid down and exposed before developing the monomeric regions of the thinner first layer.Type: GrantFiled: August 21, 1987Date of Patent: August 22, 1989Assignee: NCR CorporationInventors: George Maheras, Hubert O. Hayworth, Michael R. Gulett

Patent number: 4647524Abstract: Printed wiring boards have a first liquid photopolymer layer placed on the wiring board conductive layer over which a second photopolymer layer is laminated and both layers are photo cured in place to bond the two layers together and adhere them to the board. The liquid photopolymer layer covers wiring pattern ridges or other uneven surfaces in air free surface contact. The second layer is carried by a thin transparent plastic film for lamination onto the first photopolymer layer by a squeegee, and the plastic film is peeled off for reuse in further cycles. The carrying film is preferably pivotable in a clamshell arrangement to permit the photopolymer layer to be placed on the film and then to be laminated in two pivot positions. To prevent starvation of the liquid polymer from wiring ridges when the second layer is laminated thereon, the second layer is carried on a contoured surface with a complementary pattern to the wiring ridge pattern.Type: GrantFiled: June 19, 1985Date of Patent: March 3, 1987Inventor: Donald F. Sullivan
