Title: Apparatus for Continuously Forming Plastic-Coated Metallic Tubing.
Inventor: KAMIMURA NOBORU
IPC: B21C37/09
Filed: 1968-12-09
Abstract: 1,192,269. Making tubes; skelping. MATSUSHITA DENKO K.K. 9 Dec., 1968 [27 Dec., 1967 (2)], No. 58427/68. Headings B3A and B3E. [Also in Division B2] Apparatus for continuously forming plasticcoated metallic tubing comprises a device 5 for continuously supplying a strip of metal 1, a device 6 and 7 for continuously cleaning the strip, a device 9 for continuously forming the cleaned strip into a tubular form, a device 10 for continuously welding the seam of the tubular formed strip so as to complete a tube 14, a device 16 and 35 for applying a plastic coating to the tube, a cooling device 48 for continuously cooling the coated tube and a shearing device 50 for cutting the coated tube into standard lengths. The strip 1 is paid out fiom the reel 3 and led through an end welder 4 which connects the rear end of one strip with the forward end of a new strip. The continuous strip is then led through an accumulating station 5 so that when the supply of the strip is interrupted by the end welding operation at 4 the strip 1 will be continuously fed to the remainder of the apparatus. The strip is cleaned by passing it through a cleaner 6 and a shot blaster 7 and after passing through a hot air dryer 8 the stip is rolled lengthwise by the device 9 into a tubular form. The tubular strip is then welded by the seam welder 10 after which a seam shaver 11 removes any unevenness at the seam, a water shower 12 cools the tube and a seam brusher 13 removes any oxidized layer around the seam. The plastic coating on the inner surface is applied by placing the slidable equipment 15 on the strip at a point where the strip has a semi-circular crosssection and a powder gun nozzle 16 is inserted into the tube 14 downstream from the seam brusher 13. The tube 14 is then formed to the desired shape by sizing rolls 24, cleaned again by the equipment 25 and an acid spray station 26, and passed through a second hot air dryer 27 to a primer applying station 28. A pre-heater 34 dries the primer and fuses the plastic coating on to the inner surface of the tube after which the outer surface is coated by the equipment 35. Finally the tube 14 is passed through a cooling device 48 and cut into standard lengths by the shears 50.

Filed: 1969-12-01
Abstract: 1285049 Image pick-up tubes; Semi-conductor devices RCA CORPORATION 1 Dec 1969 [29 Nov 1968] 58491/69 Headings HID and H1K A charge storage target comprises a wafer 20 of semi-conductor material of a first conductivity type, an array of effectively discrete regions 22 of a second conductivity type forming diodes with the wafer, an insulating layer 24 covering the wafer between the regions and further s.c. material 26, which contains a dopant suitable to cause the wafer to be of the second conductivity type, on the insulating layer and in contact with the regions. A Si photodiode target for a vidicon camera tube comprises a monocrystalline P doped N-type bulk region 20, an array of B doped P-type regions 22 an insulating layer of SiO 2  and covering each region a square pad 26 of amorphous, mono- or poly-crystalline Si degenerately doped with B. The target is prepared by heating a pure Si wafer at 1100‹ C. in steam to form the layer 24 which is then etched to produce an array of openings. A layer of Si heavily doped with B is vapour deposited over the layer 24 and etched to form the pads 26. The wafer is baked at 1200‹ C. causing some B to diffuse into the wafer to form the P-regions 22. N-type impurities may be diffused into the other surface of the wafer to prevent trapping charges there. The crystal may be of Ge, GaAs or GaAs-GaP and the diodes of the mesa type. The pads need not be of the bulk material but contain or consist of elements of Groups III and V to modify the conductivity type of Si or Ge or elements of Groups II, IV or VI to modify Group III-V compounds. The modifiers may be diffused into pads formed of initially undoped material. The target may be used in solid state image sensors, storage and scan conversion tubes. In the secondary emission mode the conductivity types of regions 20, 22 are reversed. Each pad may be connected by a conductor to a solid state scan generator which applies the same potential as an electron beam to each pad. In a vidicon tube the rear face may have an antireflection coating to improve optical coupling with the tube face plate 14.
