Title: Uniform light transmitting, infrared absorbing and reflecting materials and articles
IPC: B32B7/027
Filed: 1966-01-25
Abstract: A light transmitting material or article comprising (a) a light transmitting layer which has, or which under sufficiently intense incident light or heat radiation temporarily acquires heat absorbing properties, and (b) a light transmitting layer which is, or which is capable of temporarily being rendered radiant heat reflecting and is dispersed so that it can protect layer (a) from radiant heat rays. The layers may be self-supporting layers or sheets or layers applied as a coating to self-supporting sheets which may be of glass or plastics material. The protecting layer (b) may be a coating of a metal, a metal-containing compound 01 01- a metalloid deposited directly on to the protected layer (a) or on a sheet of material which is then secured to the protected layer. Preferred coatings are of gold, silver or titanium oxide..In one form of the invention the protecting layer is sandwiched between two glass sheets, bothof which 'may be coloured,' the sheets being bonded together either by soldering at their marginal edges or by an inter-layer of plastics material e.g. polyvinylbutyral. In another form the material may constitute a double glazing unit, the protecting layer being on the outer or inner surface of one of two spaced sheets which are-secured together by a continuous metal strip soldered to copper bands deposited on the inner marginal edges of the sheets. Another form of protecting layer consists of a thin layer of a metal or semiconductor the radiant-heat reflecting properties of which can be varied by the application of an electric field. The intensity of the applied field can be controlled by means of a photoelectric cell actuated by sunlight. The protected layer may be of coloured glass (see Division C1 and may be chosen to be neutral in relation to the protecting layer. Thus, e.g. a protecting layer of gold or titanium oxide may be associated with a layer of grey glass. Alternatively the protected layer may be a phototropic layer. One such layer consists of calcium butyrate incorporated in an agar binder. This layer may be applied to a sheet of glass which is itself coloured. Other substances which may constitute a phototropic layer include polyvinyl methyl ether, alkalineearth salts of polyacrylic acid, polymerised polyvinyl partial acetals or cetals of which the ether oxygen atoms are associated with water, and hydrated salts. Still further phototropic layers comprise a light-sensitive halogenides to which halogenides of copper, cadmium or nickel may be added as catalysts. In one example of such a layer a coating containing equal parts of AgCl and AgBr is applied to a colourless glass sheet and coated first with a layer of SiO and then with calcium silicate. The material may be used for glazing or for making protective shields.

Title: Complementary mos transistor integrated circuits with inversion layer formed by ionic discharge bombardment
IPC: H01L21/265
Filed: 1967-02-02
Abstract: A monolithic semi-conductor integrated circuit comprises a substrate containing a complementary (i.e. opposite connecting types) pair of insulated gate field effect transistors. Fig. 1 shows an N-type substrate 2 with a first F.E.T. comprising P-type source 6 and drain 8 regions and gate electrode 18 on simulating layer 16 over channel region 10. The second F.E.T. comprises N-type source 22 and drain 24 regions in P-type zone 36 with gate electrode 34 over insulating layer 32 the production process is fully described. P-type zone 36 is produced by diffusing boron in two stages (the upper surface of the oxide masking being removed after the first stage) into a 5 ohm cm. N-type silicon wafer 2. Masking, deposition and diffusing techniques utilizing boron nitride and phosphorus pentoxide are used to provide source and drain regions 6, 8, 22 and 24. The channel insulating regions 16 and 32 are provided by passing dry oxygen to form a first oxide layer 500 which, depositing a 200 layer of doped oxide by decomposition of a mixture of tetraethylorthosilane, trimethylphosphate and argon and then growing a third 100 thick layer of silicon dioxide after the first and last oxidizing step the dimer is cooled in dry oxygen. The doped layer discourages the formation of an uncontrolled channel inversion layer. Photoresist masking is used to expose the source and drain regions to ion bombardment in argon which improves adherence of aluminium which is then evaporated on to form contact electrodes. The treatment is repeated to provide gate electrode 18 and a thicker aluminium coating on regions 6 and 8 and the aluminium layers are then alloyed to form ohmic contacts. A third ionic bombardment is used to create acceptor sites in the channel oxide layer 32 to facilitate formation of the N-type inversion layer and another coating of aluminium is provided forming the source, drain and gate electrodes. The semi-conductor material may consist of Ge, Si, or GaAs. Fig. 11 shows an inverter circuit utilizing the device. The two gate electrodes are connected to input lead 94 and the two drain electrodes connected together by lead 96. P-type source electrode 82 is connected to a potential Vb. If V b is applied at input 94, P-type channel transistor 3 is cut off and N-type channel transistor 5 conducts to provide zero volts at output 98 similarly zero volts at input 94 means the P-type channel conducts and the N-type channel is cut off to provide potential V b at output 98.

Title: Tape motion control in an incrementing magnetic tape transport
IPC: G11B15/18
Filed: 1974-08-10
Abstract: In a rotating head magnetic tape transport, the tape is maintained stationary as the head sweeps a selected data track. A length of tape is buffered in a vacuum column between a supply spool and the rotating head station. A take-up spool on the opposite side of the head station is servo controlled to maintain proper head/track alignment and to periodically step the tape to an adjacent track. Changes in the tape radius on the take-up spool are compensated for by (1) a stop-lock source of motor energization whose magnitude is servo controlled by unbalance between the vacuum column force tending to pull the tape in one direction and the take-up spool motor torque tending to pull the tape in the opposite direction, and (2) a step modification network which responds to head/track alignment error caused by the variable tape radius on the take-up spool.

Title: Single phase asynchronous motor electronic control - has HF oscillator synchronized with supply for triac firing
Inventor: REYNA LANDECHO LUIS
IPC: H02P25/04
Filed: 1976-06-25
Abstract: The circuit for speed control of a single-phase asynchronous motor sets the terminal voltage of the motor by adjustment of the firing angle of the traic (8). The shaft of the motor (1) is coupled to a tachogenerator (2) controlling the saw-tooth voltage oscillator (3) which is synchronized with the frequency of the supply network. The oscillator fires the triac (8) through the trigger circuit (4). The output of the tachogenerator (2) is blocked by a comparator (5) as long as the motor speed is below the set limit. At the same time, the -comparator (5) controls the periods of the oscillator (3), and the effect of changes in the supply voltage upon the speed control is eliminated by a detector (10) which corrects the response of the system. The corrective action is facilitated by the adjustable ramp control circuit (6) between the comparator (5) and the oscillator.
