Title: Cartridge for use in magnetic recording and or reproducing apparatus
IPC: G11B23/00
Filed: 1972-09-13
Abstract: 1406084 Reels SONY CORP 13 Sept 1972 [17 Sept 1971 21 Sept 1971 21 Dec 1971] 42584/72 Heading B8M Part B An endless tape cartridge for use in video recorders includes at least one aperture in a peripheral wall, and a cover 50 therefor which co-operates with a reel locking lever 66 for engaging reel flange 74, to lock reel 30 against rotation when the cover 50 is closed. As shown, the cover 50 is flexible and is manually slidable in tracks 40 in the top and bottom of the cartridge to cover apertures 261, 28<SP>1</SP> provided for tape withdrawal and return respectively. The lever 66 has an end 68 engaging one of notches 78 on the reel flange 74, and the other end 80 extends into the path of the cover-plate 50 and is pivoted thereby against a spring 70 when the cover plate 50 is opened, to unlock the reel 30. In use, a tape loop is manually extracted from the cartridge, and such extraction is facilitated by a spring strip 62 adjacent the aperture 28<SP>1</SP> which biases the tape outwardly. Means are provided for retracting the tape loop when the cartridge is not in use, comprising a lever 90 pivoted about reel shaft 32 and including two depending pins 92, 94 both of which intersect the tape path when the lever 90 is moved clockwise, between a guide pin 86 and the tape coil, and between guide pins 34, 86, respectively, to form tape loops (95), Fig. 9 (not shown). The lever 90 is caused to pivot thus by a slide 100 having a rack 98 engaging a gear 96 on the lever 90. The slide 100 is movable manually along tracks 104, against a spring 108, by an arm 110 extending through side wall 24, and is then latched, the tape loop being retracted, by a lever 116 engaging ratchet teeth 122 thereon. The latch 114 may be released, either automatically as the cover 50 is opened, an internal protrusion (132), Fig. 10 (not shown), on cover handle 52 engaging the lever 116; or manually, the latching lever (142), Fig. 12 (not shown) having a leg (146) extending through side wall 24. A tape guide member 82 (also Fig. 8, not shown) includes a curved, outwardly flared surface 88 to guide tape leaving the innermost winding 16<SP>1</SP> through the aperture 26<SP>1</SP>, and a pin 89 located between the innermost winding 16<SP>1</SP> and the rest of the windings to facilitate tape withdrawal.

Abstract: 891,112. Converter chimneys. VORKAUF, H. Dec. 16, 1960 [Oct. 8, 1960], No. 43417/60. Class 25 [Also in Group XIII] A converter or like installation chimney which utilizes the heat contained in the intermittently available waste gases emanating from the converter to generate steam comprises cooling tubes lining the walls through which tubes water flows both by gravity and by the help given by a circulating pump at certain periods. A converter chimney 1, Fig. 1, comprises a lining of cooling tubes which are both in a gravity flow circuit from a steam separation drum 4 and downcomer pipe 3 and also, when desired, in a forced flow circuit created by a circulation pump 6 which draws water from the drum 4, piping 5, 8 and a non-return valve 7, which forced flow circuit is connected to the downcomer pipe 3 by a nozzle to effect a suction effect on the water in the pipe 3. The pump is operated only at certain periods of operation of the converter 9 e.g. shortly before or after the blowing of the converter 9 and the pump may be started by swinging the converter into its blowing position. In a modification the pump discharge pipe 8, Fig. 2, may be led into the header 10 supplying water to the cooling tubes 11 and water from the forced circuit pump is supplied through nozzles 12 to each cooling tube.

Abstract: 1481196 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 11 Oct 1974 [31 Oct 1973] 44122/74 Heading H1K In a method of manufacturing a semi-conductor device in which an initial insulating film 122<SP>1</SP> is formed on a semi-conductor substrate 120, openings are formed in the film 122<SP>1</SP>, a conductivity-modifying step such as diffusion is effected in the openings and, preferably simultaneously with the last-mentioned step, a further insulating film 127<SP>1</SP>, 125<SP>1</SP> is formed both in the openings and over the remainder of the substrate surface, the thickness of the initial insulating film 122<SP>1</SP> is chosen such that for a given set of conditions in the subsequent processing steps the final insulating film has either (a) a planar upper surface as shown or (b) a constant thickness, its upper surface being profiled to follow the contours of the underlying substrate surface. The invention thus exploits the higher growth rate of insulating material, particularly oxide, on exposed semi-conductor than under the initial insulating film 122<SP>1</SP>. Fig. 4c illustrates an intermediate stage in the manufacture of a Si MOSFET wherein both films 122<SP>1</SP> and 127<SP>1</SP>, 125<SP>1</SP> are of SiO 2 , thicknesses and oxidation conditions therefor being specified. The film 127<SP>1</SP>, 125<SP>1</SP> forms during the drive-in diffusion of source and drain regions 124<SP>1</SP>. The thickness of the film 122<SP>1</SP> to achieve the planar upper surface shown is 1000 . For the same subsequent processing conditions an initial thickness of 3000  for the film 122<SP>1</SP> would have resulted in a structure satisfying criterion (b) above. The device is completed by etching through the insulation to the substrate in the gate area, regrowing a thin gate insulation, opening source and drain contact windows and depositing appropriate electrodes. Bipolar transistor manufacture is also briefly disclosed.
