Title: Improvements relating to photography
IPC: G03B17/52
Filed: 1964-08-04
Abstract: 1,59,850. Photographic sheet materials. INTERNATIONAL POLAROID CORPORATION. Aug.4, 1964 [July 31, 1963], No.31070/66. Divided out of 1, 059, 849. Heading G2A. A gas and water impervious container has therein a coiled sheet impregnated with a solution of an alkaline processing liquid, the end of the sheet extending from the container through a narrow slot therein which is sealed against admission og gas or vapour. This sheet, 84, is the print-receiving sheet, to which the image is transferred from the light-sensitive sheet which is exposed in the camera, by pressing the sheets together between rollers. Sheet 84, in roll form in a container, is housed in a chamber 82 of the camera, and is drawn between rollers 164, 166 in contact with the exposed sheet. As the two sheets are pressed together, development of the exposed image and its transfer from one sheet to the other take place. The print-receiving sheet is prepared by coating a suitable paper support with a polyvinyl butyral solution, to render it impermeable to the alkaline processing liquid. Further coatings of specified solutions are applied, and the sheet then has a permeable structure suitable for absorbing the processing liquid itself by immersion therein. This is a strongly alkaline solution having a pH of at least 12, and an example is given comprising potassium hydroxide as the main constituent. Sheet 84 is supplied in the container (118) Figs. 1, 2 (not shown), which may suitably be of polyethylene, having an opening formed as a slot between overlapping lipped edges. A leading edge of the sheet extends out of this slot, which may initially be closed with wax to make a gas and water tight seal, until such time as it is required for use. To prevent evaporative loss of processing liquid, the atmosphere inside container (118) can be kept in a saturated state by a reservoir of water or processing liquid. This may be provided as excess liquid on the print-receiving sheet itself, or by an impregnated layer of absorbent material lying round the outside of the roll 84. In order to maintain the high pH level of the processing liquid, a substance may be included to act as a getter for carbon dioxide. Such substance may be an alkali metal hydroxide which forms, with CO2, a carbonate less soluble than that produced by the hydroxide in the processing liquid. The chamber 82 housing the container (118) is itself lined with a sealing material to prevent admission or escape of water vapour and CO2. As shown, the lining comprises sections (142) and (148) Fig. 1 (not shown), of a suitable elastomeric material, which form a seal round sheet 84 as it passes out of the chamber. Details of the camera itself are described in Specification 1, 059, 849.

Title: Method of adjusting the threshold voltage and saturation current of field effect transistors
IPC: H01L21/338
Filed: 1975-07-25
Abstract: 1510683 Manufacture of field effect transistors THOMSON-CSF 25 July 1975 [26 July 1974] 31327/75 Heading H1K In the manufacture of one or more JUGFETs in a semiconductor wafer the source, drain and channel regions and gate junction of each JUGFET are formed simultaneously with corresponding ones of a test structure and then the threshold voltage is adjusted by simultaneously bombarding the channels of the JUGFETs and test structure with ions of a conductivity type determining impurity, measuring the threshold voltage of the test structure continuously during bombardment or in periodic interruptions thereof and terminating bombardment on reaching the desired value. As described JUGFETs with Schottky gates and test structures, one for each set of JUGFETs required to have different threshold voltages, was formed on a P-type silicon wafer by coating with a thick oxide layer, aperturing this at JUGFET and test structure sites, reforming oxide thinly there, forming a resin mask with apertures at the sites of source and drain zones which are then formed by ion implantation, removing the mask, implanting to form lightly N-doped channel regions under the thin oxide and then forming source, drain and gate contacts by aperturing the thin oxide, depositing palladium alloying it to silicon exposed in the apertures and removing unalloyed material. Then the structure is bombarded overall, or only in channel regions exposed through a new mask, to implant either arsenic or boron ions to respectively increase or decrease the threshold voltage, as measured by the test structure, to the required value, the implantation process being repeated using a different mask when devices of different threshold voltage are required. As described the gate of the test structure has an enlarged extension to facilitate contacting by test probes. After annealing upper contact layers of molybdenum-gold alloy are provided.
