Patent ES-292346-A1 (ES)
Title: Improvements in or relating to methods of producing sheets of wood veneer and the sheets of wood veneer so produced
IPC: B27L5/00
Filed: 1963-10-09
Abstract: A method of producing a sheet of wood veneer comprises the steps of cutting a plurality of laminations, uniting the laminations using a adhesive to form a block having the grain of all the individual laminations running in parallel, the laminations being similarly bent to form a concavity running along a central portion of one surface of the block in the same direction as the grain of the laminations, and slicing the block with a knife which acts to cut successively across the layers of adhesive to produce sheets of figured veneer having smooth surfaces. The laminations 1 with adhesive, such as synthetic resin, therebetween are placed between the dies of a pressing apparatus, such as that described in Specification 1,107,823, and pressed to set the glue and form a block 6 with a U- or V- shaped concavity and the grain 5 and flower 4 running in the direction shown in Fig. 2. The block is then mounted in a jig 7 of a rotary peeling machine and a veneer 10 peeled from the block by a knife 9. With a veneer so produced, the artificial flower runs substantially parallel to the grain of the wood. Variations in the pattern of the veneer may be obtained by introducing small chippings between the laminations during the production of the block, and by using laminations of differing colours.

Title: Improvements in the electrophoretic analysis of radioactive substances
IPC: G01N27/447
Filed: 1964-09-16
Abstract: Radio-active substances are analysed by subjecting them to electro-phoresis and measuring the radio-activity at points along the electrophoresis medium. The medium comprises a paper or plastics strip 12 which dips into electrolyte 14, 15 and to which a potential may be applied by electrodes 10, 11. The strip is covered by a plate 19 opaque to radiation having holes 22 containing copper discs 20 with slits transverse to the strip 12. Geiger counters 18 measure the radio-activity of the strip beneath the slits. The counters are located as close to one another as their size allows. The sample is introduced under one of the counters and the output of that counter and those nearer the anode is recorded. The level to which the output of the counter at the point of introduction falls indicates the activity of elements present colloidally as these do not migrate, and elements in the ionized state and combined with protiens are indicated by peaks on the records of the other counters.

Title: Igfet with interdigital source and drain and gate with limited overlap
IPC: H01L23/482
Filed: 1967-02-16
Abstract: An insulated gate FET comprises a body of one conductivity type having interdigitated source and drain regions defining a meandering channel, the source and drain regions each having a low resistivity base portion from which the fingers extend, and the gate being disposed over, and insulated from, the fingers of the source and drain regions and the channel. As shown, Fig. 2, the device comprises source and drain regions 13, 15 defining a meandering channel 17, and having heavily doped contact regions 11, 12 and interlocking fingers 14, 16. The gate electrode 18 extends across the fingers 14, 16 and defines the active sections of the channel. The device operates in the enhancement mode but can be converted into a depletion-mode device by providing a surface conduction channel region between the source and drain regions. The device may be produced in a wafer of P-type silicon by oxidizing, photomasking and etching with ammonium fluoride and hydrofluoric acid, diffusing-in phosphorus to form N+ source and drain contact regions, exposing the required source, drain and channel regions, masking the meandering channel region using an electron beam to decompose an atmosphere of oxygen containing tetraethoxysilane, heating in wet argon, diffusing-in arsenic to form source and drain regions, removing the meandering channel mask, oxidizing the whole surface, opening windows for the contacts, and depositing aluminium to form the source and drain contacts and the gate region. The device may be mounted on a header and encapsulated. An N-type surface channel region for the depletionmode devices may be produced by a donor diffusion before forming the channel mask. Alternatively this region may be formed as an inversion layer during application of the gate insulation. Other active and passive devices may be provided in the substrate. The use of the transistor in a tuned amplifier is also described, Fig. 5 (not shown).

Patent ES-392877-A1 (ES)
Title: Solid state image sensing device
IPC: H04N3/15
Filed: 1971-07-03
Abstract: A solid state imaging device for receiving and storing an optical image is composed of an array of photosensitive diode elements or p-n junctions as a first and second region with the further formation of a common collector region. coincident selection of individual storage elements is by virtue of capacitive coupling to row and column lines, and cyclical scanning devices provide a stored charge on the p-n junction which is reduced in proportion to the totality of photons incident upon the storage device. Suitable outputs upon recharging are derived from the common collector region. The central or second region is connected to a point of reference potential such as ground for reducing the effect of the capacitive coupling between accessing wires and output leads by virtue of the electrostatic shielding provided by the grounded second region.

Patent ES-467326-A1 (ES)
Title: Channel bus controller
IPC: G06F13/12
Filed: 1978-02-25
Abstract: The Channel Bus Controller (CBC) transfers information between groups of input/output channels and processor storage. Storage receives or dispenses two data words per access operation. Interfaces for transfers from the channel groups to the CBC are advantageously one word wide since each output (fetch) request consists of a single request word. Information sent by each group is assembled into three-word units (a request word and zero, one or two data words) in a respective channel bus assembly register (CBAR). The assembled unit is passed from the CBAR to a respective area of an In Buffer array and from that array to storage. Zero filler words are inserted into unused data word positions. A channel request may be tagged to designate a transfer of four data words. If the transfer is an input the four data words are sent to the CBC with a single request word. The third and fourth data words are written in the CBAR over the first and second data words as (or after) the unit formed by the request and first and second data words is advanced to the In Buffer. The same request and the third and fourth data words are transferred as a second unit from the CBAR to the In Buffer. The low order bit in the address part of the request is inverted by the CBC to designate the "next" storage address. This saves time by eliminating a request unit transfer from the source channel group. Request transfers from a group are permitted when a vacancy exists either in the respective CBAR or in a respective area of the In Buffer. Outputs from storage (acknowledgments of data inputs and fetched/output data) are returned to the respective channel group via a respective area of an Out Buffer array. Returns to a group are ordered in the input sequence of respective requests to the CBC although the requests may be applied to storage in another sequence. Tags generated by the CBC are used to maintain the correct output order without delaying evacuation of the In Buffer. The area partitioning of the in and out buffer arrays provides balanced group access to storage and simplifies handling of group traffic. Channel identity information in the request words is looped through the buffer arrays and returned to the channel groups with respective outputs. This permits the CBC (and storage) to ignore channel origins of group traffic and thereby further simplifies handling of traffic.
