Title: Method for making closely spaced conductive layers
IPC: H01L49/02
Filed: 1967-10-30
Abstract: In order to form two spaced conductive layers which are free from short circuits the two conductive layers are separated by a thin film of material which is subsequently removed by dissolving to expose any pin hole shorts which are then eliminated. A thin film capacitor, Fig. 1, is formed by depositing a gold layer 2 on an insulating substrate 1, then a copper film 3 and finally a second gold layer 4, the two gold conductive layers forming a cross-over. The copper filler 3 is removed by etching so as to leave an empty space between the layers 2 and 4 and expose any pin-hole shorts such as 5. The shorts may be removed by oxidization, immersion in a transducer-agitated liquid, ultrasonic cleaning or centrifuging. A dielectric may be produced in the space between the layers by forming oxide layers on the internal surfaces of the conductor layers or anodization. In a second embodiment, Fig. 3, a thin film cross-over is produced between contacts 11, 12 over conductor 13. The contacts 11, 12, and conductor 13 are deposited on a silicon substrate 10 coated with SiO 2 or SiN 2 and comprise titanium 14, platinum 15, and gold layers 16. A layer of zirconium 17 is deposited where indicated and a copper spacer layer 18 positioned on the top thereof. Contacts 11 and 12 are then joined by an upper gold layer 19. The copper layer 18 is again etched away to expose any shorts which are eliminated and the zirconium 17 is oxidized.

Title: Blade ring support
IPC: F01D25/24
Filed: 1969-01-18
Abstract: In an axial-flow steam turbine or like machine having a casing divided along a horizontal plane into upper and lower halves 11, 10 respectively a stator blade ring 16, 18 is supported within the casing by substantially diametrically opposite dowel pins 24, each having a circular portion 32 engaging an opening 34 in the lower half 16 of the blade ring and an eccentric flat sided head portion slidably engaging a recess 26 in the corresponding half 10 of the casing. The head of each pin 24 has four sides 36, 38, 40, 42 each at a different distance from the pin centreline so that the position of the blade ring 16, 18 in a vertical plane can be adjusted at assembly by rotating the pin 24 about its centreline. The lower surface of the head of each pin 24 rests on a flat liner 28 secured to the lower half 10 of the casing by screws 30 and is prevented from riding up out of recess 26 by a member 44 held in position by screws 46. The sum of the dimensions A and D of the pin head head is equal to the sum of B and C so that the member 44 always engages the head but permits sliding of the head in the axial direction of pin 24 when thermal expansion of the blade ring or casing occurs. The opening 34 is tapered and the pin 24 may be secured therein solely by friction or, as shown, by a locking pin 48 screwed into one of four holes 50 in the pin 24. To assist in removal of the pin 24 at disassembly, recesses 52 are provided in the pin 24 adjacent the holes 50 so that, after removal of locking pin 48, liquid under pressure can be injected into chamber 54 to force the pin 24 out of its opening 34.

Title: Lubricated blade cleaning of imaging photoconductive members
IPC: G03G21/10
Filed: 1969-01-30
Abstract: Toner particles retained on an electrostatographic imaging surface after transfer of a developed image are removed by at least one cleaning blade assembly comprising at least one flexible cleaning blade having an angular imaging surface engaging edge and being mounted to permit the cleaning blade to align itself parallel to the imaging surface when engaged with the imaging surface, a dry solid lubricant being supplied to the imaging surface. In the embodiment shown in Fig. 14, the blade 390 with a rigid backing plate 352 is mounted within the jaws of a blade holder 354 pivotly mounted on a shaft 360, the shaft being permanently secured to a hinged member 362. The hinged member has an extension 388 which carries a roller cam follower 384 which engages with a cam 382 fixed to the cylindrical imaging surface 364 so as to disengage blade 390 from the imaging surface once per revolution of the drum. The ridge of toner particles accumulated by the blade is thus transported on the moving surface and removed by cascading developer in the developing apparatus. Any toner particles which gravitate away from the blade are collected in a trough (not shown). In place of the cam, the drum may have transverse grooves (52), Fig.2 (not shown) into which the ridge of toner particles is lodged by the action of the blade, the trailing edge of the groove being of such angle that it sweeps the leading edge of the blade. The toner particles are again collected in the developing apparatus. Several blades may be provided extending across the drum surface either as separate units, Fig. 16 (not shown) or combined as one unit, Fig.17 (not shown), or alternatively, Fig. 18, the blades 450, 452, 454 extend part way across the surface in a staggered array, grooves 464, 466, 468 of less extent than the blades being provided in the drum surface. In a further embodiment, Fig. 9 (not shown) the blade has a flexible metal backing and is supported in the manner of a windscreen wiper blade. The electro-photographic apparatus may be of the line-by-line type with a drum, or of the whole frame type using an endless belt. The solid, dry, lubricant may be mixed with the toner, or applied to the developer from a separate hopper. In the case of apparatus using an endless band, a lubricant powder cloud generator is described. Alternatively, the lubricant is dispersed throughout the photoconductive layer or suspended in a photo-conductive overcoating layer. Suitable lubricants are metal salts of fatty acids, examples being zinc, barium, lead, iron, nickel, cobalt, copper, strontrium, calcium, cadmium and magnesium stearate zinc, manganese, iron, cobalt, copper, lead and magnesium oleate zinc, cobalt, copper, magnesium, aluminium and calcium palminate lead caprylate lead caproate zinc, cobalt and calcium linoleate zinc and cadmium ricolinoleate higher aliphatic acids such as stearic and palmific acid and colloidal pyrogenic silica particles. The lubricant may be chosen to have the same as or a contrasting colour of the receiving sheet.
