Title: Transistors
IPC: H01L29/73
Filed: 1965-08-24
Abstract: 1,108,774. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. 24 Aug., 1965 [13 Oct., 1964], No. 36220/65. Heading H1K. A method of making a transistor includes the steps of providing a body of semi-conductor material having successive layers alternating in conductivity type, the material having the property that the mobility in it of one type of carrier is substantially greater than the mobility of the other type of carrier, and defining the active portions of the emitter and base regions in the body by alloying an electrode through the emitter region, which is located at the surface of the body, to reach the base region immediately below the emitter region, the emitter region having an impurity concentration which is substantially less than the impurity concentration in the base region at the interface between the two regions. Suitable semi-conductor materials are gallium arsenide, in which the electron-hole mobility ratio is about 11, and indium antimonide in which the ratio is 30-50. In the preferred embodiment a lightly doped N-type layer 1 is formed epitaxially on a highly doped N-type substrate 2 and an acceptor impurity such as zinc is diffused into the layer 1 to produce a P + base region 3. The impurity concentration at the surface of the region 3 is about 10<SP>18</SP> atoms/c.c. A lightly doped N-type emitter region 4 having an impurity concentration of about 10<SP>17</SP> atoms/c.c. is then epitaxially deposited on the region 3 at such a temperature that the diffusion of impurities is not significant. The impurity in the region 4 may be selenium. A base electrode 6 is formed by alloying zinc through the region 4, rapid heating to the eutectic point followed by rapid cooling producing the regrowth region 5. The emitter electrode 7 is formed as an ohmic contact to the active central portion of the emitter region.

Title: Brake method and device
IPC: F16D55/00
Filed: 1970-07-28
Abstract: 1318914 Spot-type disc brakes; actuation; wear compensating PONT-A-MOUSSON SA 28 July 1970 [11 Aug 1969] 36375/70 Heading F2E In a spot-type disc brake the braking force has a major component urging the brake pad assembly in a direction opposed to the normal direction of movement of the disc, and a minor component urging the brake pad towards the disc; a fixed support co-operating with the side of the brake pad assembly remote from the disc affords a reaction for the brake pad assembly which is slightly inclined relative to a perpendicular to the disc face, so that the reaction has a major component perpendicular to the disc face and a minor component in the direction of movement of the disc; preferably wearcompensating apparatus is provided. As shown, a fixed support 4, Fig. 2, has an opening through which extends part of the periphery of a rotatable disc 1. To the fixed support is screwed, at 15a, a support block 15, Fig. 3, having a cylindrical cavity 16 within which a nut 18 is keyed at 17. To the outer face of the nut 18 is secured a support plate 19, preferably having located in front of it a roller bearing cage 20 containing rollers 21. The cage is urged to the left by a spring strip 23. In contact with the rollers 20 is the bearing face 5b of a wedge-shaped part 5<SP>111</SP> of a brake pad 5, the pad friction face 5a being parallel to the disc 1. A small acute angle y is included between bearing face 5b and the disc surface S, and between the axis X-X of cavity 16 and the perpendicular Y-Y to the disc. A force-amplifying lever A pivoted at 10 to the fixed support 4 has pivoted to it at one end a rod 12 of a servomotor 13, Fig. 2, connected to a pressure fluid source, and at the other end a brake applying lever 6 secured to the brake pad 5. The brakeapplying lever 6 is so mounted that the braking force F, Fig. 3, is also at the angle y to the braking surface S. In operation, when servomotor 13 is pressurized, rod 12 is expelled slightly, so lever 9 is pivoted counter-clockwise and pad 5 consequently moved to the right with rolling movement of rollers 21. This pad movement is in opposition to the direction of rotation, f, of disc 1. The brake is release on de-pressurizing the servomotor 13; when pad 5 is sufficiently withdrawn for rubbing between itself and disc 1 to cease, spring 23 acting through rod 22 returns cage 20 to the left. As shown in Fig. 2, a pad-lever-servomotor assembly is provided on each side of the disc 1. Wear-compensating.-Within nut 18 is a rotatable screw 24 having a flange 25 and a ratchet wheel 26. A spring strip 27 secured to servomotor rod 12 acts as a pawl on ratchet wheel 26. If sufficient wear has occurred to cause rod 12 to travel a distance exceeding the tooth pitch of ratchet wheel 24 (a distance greater than normal) before the brake is applied, pawl 27 passes over the edge of the next tooth. Then, on the release stroke, pawl 27 rotates ratchet wheel 24 to advance nut 18 towards disc 1.

Title: Improvements in or relating to fluorescent electric discharge lamps
Inventor: FOWLER KENNETH EDWARD
IPC: H01J9/22
Filed: 1961-10-11
Abstract: A method of producing a coating of phosphor on the interior surface of a glass envelope of a discharge lamp comprises depositing the phosphor within a coating of a synthetic resin of the fluorinated hydrocarbon type, the coating being subsequently dried and hardened by heating: in a modification the resin containing a dispersion of the phosphor is extruded in the form of a tube to be used as the envelope of the discharge lamp. Resins used can be those formed by polymerizing fluorine-substituted unsaturated hydrocarbons such as polytetrafluoroethylene or polymonochlorotrifluoroethylene. The ethylene groups can be partially replaced by equivalent propylene groups.  Polyvinyl fluoride is also referred to. The phosphor can be dispersed in the powdered resin which is suspended as an emulsion in a liquid medium. The inner surface of the envelope can be given a coating of the resin, upon which there is deposited, e.g. by electrostatic precipitation, a layer of phosphor and then a second coating of the resin. In a further arrangement a thin sheet or tube of the resin containing a dispersion of the phosphor is inserted into a glass envelope and sealed thereto by heating. The phosphor-resin coating can be applied to an envelope which provides a discharge path of sinuous form and which can be constituted of complementary parts, e.g. a flat part and a corrugated part, sealed together at their periphery. The complementary parts can be of coated glass or of the resin-phosphor mixture of of the resin coated with the resin-phosphor mixture.

Hollow filaments of synthetic organic thermoplastic polymeric material are produced by melt spinning the material through a spinneret under such conditions that the " die swell factor " of the material is between 2À5 and 10, the spinneret being provided with at least one unobstructed extrusion orifice which defines, without completely surrounding, an area of the spinneret face devoid of orifices, or being provided with two or more unobstructed extrusion orifices which define, without completely surrounding, an area of the spinneret face devoid of orifices. The minimum distance between the adjacent ends or terminal portions of the circumscribing orifice or orifices is between 3 and 15 mils. (0À076 and 0À38 mm.). The molten polymeric material may be extruded through the spinneret under such conditions that the " die swell factor " of the material is between 2À5 and 10, and the average diameter, D 2  of the imperforate area of the spinneret being greater than AD 1 , wherein A is the die swell factor of the polymeric material and D 1  is the maximum orifice width in a direction radial to the centre of the imperforate area. The imperforate area may be defined by at least two separate and distinct orifices having " shape factors " greater than 1À4. D 2  may be greater then 2 AD 1 . The expression " die swell factor " is defined as the ratio of the maximum diameter of the stream of extruded polymer melt to the diameter of the orifice opening when employing a spinneret having a circular orifice sufficiently remote from any other orifices of the spinneret that the stream does not coalesce with the stream or streams extruded from any other orifice or orifices which may be present in the spinneret. The expression " shape factor " is defined as the ratio of the longest straight line which can be drawn within a cross-section of the orifice to D 1 . The molten polymeric material used may comprise a dispersion of a first polymer as a distinct discontinuous phase within a continuous phase of a second polymer. The first polymer may be a polyester such as a polyethylene terephthalate and the second polymer may be a fibre-forming polyamide such as a polycaproamide.
