Abstract: Method of modifying an aromatic polymer surface to improve adhesion of a metal layer thereon and to the articles produced therefrom. The surface of the aromatic polymer such as polycarbonate, is nitrated by a contact with a nitrating solution such as a mixture of nitric and sulfuric acid and then hydroxylated by a contact with a hydroxylating solution such as ammonium hydroxide. The hydroxylated surface is thus chemically modified to become hydrophilic. The chemically modified surface is electrolessly plated with a primary metal layer. A secondary metal layer is then electrolessly or electrolytically applied on top of the primary metal layer until a metal layer of a desired thickness is attained. 
     The present invention further discloses articles such as an EMI shielded enclosure or a printed circuit board having metal layers as an EMI shield or a conductive metal trace pattern respectively.

Abstract: Apparatus and method are described for controlling thickness of plastic films produced by the blown film process. The apparatus is an air cooling ring modified to include devices for locally modifying the temperature of the air discharged from the air ring onto the blown bubble. Local variations in the temperature of the cooling air applied to the surface of the bubble result in variations in the bubble cooling rate and viscosity, with consequent variations in thinning during transverse bubble expansion. The method comprises centrally the location and extent of local temperature variation applied to the bubble in response to comparison of measured film thickness with a desired film thickness.

Abstract: In a codec having a coding section A/D converting an analog signal into a digital signal, and a decoding section D/A converting a received digital signal into an analog signal, a decoding timing generating circuit (50) is provided to generate a D/A conversion timing signal (S50) on the basis of a clock signal (S30b) generated by a coding PLL circuit (30) and a reading completion signal (S61a) supplied from decoding controller (61). In synchronism with this signal (S50), a D/A converter 62 converts the digital signal Di read by the decoding controller 61, into an analog signal, and sends it to the decoding filter 63. The decoding filter (63) operates synchronism with the clock signal (S30b) generated by the coding PLL circuit (30) to filter the output of the D/A converter (62), and outputs it as the analog signal (Ao). The S/N ratio due to asynchronous noises is improved, and the size, complexity, and the power consumption of the overall circuit are reduced, so the codec is suitable for implementation in an integrated circuit.

Abstract: Texture features are defined not only by mathematical functions but also by input through an input device such as a tablet, and also texture features can be displayed simply and be previewed easily. 
     Evaluation values concerning each position within a specified two-dimensional coordinate range are output for each position coordinate of each line segment; such evaluation values are accumulated for each position within the two-dimensional coordinate range; two-dimensional graphics information is output according to the accumulated evaluation values; and graphics are displayed according to the two-dimensional graphics information. Because information concerning line segments is thus separated from information as to how to model line segments, this invention enables hand-written input of information concerning line segments and also enables a preview to be performed by use of skeleton information.

Abstract: A phase-shifting lithographic mask (500 or 600), for use in conjunction with optical radiation of wavelength X, has a transparent substrate (10) upon which are successively located a bottom (2m+1)π radian phase-shifting layer (11) and a patterned top (2n+1)π radian phase-shifting layer (12) each having at least approximately the same refractive index at the wavelength λ as that of the substrate. A more finely patterned, opaque chromium layer (13) is located on the patterned top phase-shifting layer. The bottom phase-shifting layer is chemically different from both the substrate and the top layer, in order to provide either etch-stopping or end-point etch detection during subsequent dry ion beam millings--as with gallium ions--of either or both of the layers, for the purpose of mask repair. For example, the substrate is quartz (silicon dioxide), the bottom phase-shifting layer is calcium fluoride, and the top phase-shifting layer is silicon dioxide. Remnants of the gallium then can be removed, if need by, from both the exposed portions of the substrate and of the bottom layer--such as by forming indentation regions (52; 51) by means of successive etchings, for example, with HF and HCI, respectively, for respective prescribed time intervals having a ratio such that the relative phase shifts of the substrate and both phase-shifting layers are not disturbed by the respective etchings.

Abstract: A method for delivering foreign genetic material into immature embryos isolated from monocotyledonous plants, paticularly those of the Gramineae family is described. The method involves the isolation of immature embryos from the desired plant species, culturing the immature embryos for a period of time on a medium capable of inducing callus formation, introducing the foreign genetic material into the immature embryos and selecting transformed callus tissue to be regenerated into whole plants. Immature embryos that have undergone the culturing process prior to transformation exhibit a higher frequency of transformation when compared to that from freshly isolated immature embryos. The genetic material is preferably delivered by either electroporation or microprojectile bombardment methods.
