Title: Improvements in or relating to etching of openings in films
IPC: H01L21/033
Filed: 1968-01-04
Abstract: 1,203,341. Etching. INTERNATIONAL BUSINESS MACHINES CORP. 4 Jan., 1968 [9 Jan., 1967], No. 662/68. Heading B6J. [Also in Division H1] An opening is etched in a film by forming a first layer of photoresist on the film, exposing the layer through a first mask to form a first pattern, thereafter exposing the first layer, or a second layer formed over the first layer, through a second mask to form a second pattern which overlaps the first pattern, the area of overlap defining the opening developing the layer(s) and etching the exposed surface of the film. The film may be an insulating layer 12 (e.g. silicon or germanium oxide, silicon nitride, alumina or glass) provided on a semi-conductor substrate 10 (e.g. silicon or germanium). A first photoresist layer 14 is exposed thzough a first mask and developed to produce a first aperture 16 and a second photoresist layer 18 is exposed through a second mask and developed to produce a second aperture 22. The exposed area of layer 12 is etched (e.g. with buffered H.F.). The aperture defined by the second mask may be larger than that defined by the first mask (e.g. the second aperture may encompass two smaller first apertures). In an alternative procedure a single photoresist layer may be exposed successively through first and second masks. The photoresist may be stripped from the etched layer 12 and a P or N region 26 diffused in to provide a collector, base or emitter region or an isolation or inversion preventing region. In a further example, Fig. 2, two photoresist layers 14A and 18A are exposed through separate masks as above to produce an aperture 22A in an insulating layer 12A composed of glasses or silicates. The aperture permits a metal contact 28A to be provided and to form a terminal contact to a metal land 13 which is in ohmic contact with a semi-conductor region 10A.

Title: Improvements in the manufacture of textile and other materials having a basis of cellulose triacetate
Inventor: HAWTIN SELWYN GEORGE
IPC: D01F2/30
Filed: 1956-01-11
Abstract: Wet spun or dry spun textiles and other extruded or cast materials such as films made from cellulose triacetate have "effect materials" incorporated in them by making a solution of (a) an acetone-soluble cellulose acetate in which an effect material has been dispersed, and (b) a considerably larger proportion by weight of cellulose triacetate, and shaping and coagulating the solution.  "Effect materials" include pigments, dyes, fire-retardants, fillers, softening agents, sizes, resinous materials, catalytic reagents and lubricants.  Particles of acetone-soluble cellulose acetate containing effect material may be added to a cellulose triacetate solution which is then coagulated or the said particles (so-called "lacquer chips") may be first dissolved in a cellulose triacetate solution to form a "concentrate" which is then added to the main cellulose triacetate solution prior to spinning or otherwise coagulating. A method of adding the lacquer chips directly to the cellulose triacetate solution before coagulation is also described. The acetone-soluble cellulose acetate and cellulose triacetate are preferably dissolved in solvents of substantially neutral composition, and as solvent may be used methylene or ethylene chlorides, or methylene chloride-methanol mixtures with 6-14% by weight of methanol.  The solution when ready for coagulation may contain not more than 8% of acetone-soluble cellulose acetate, based on the weight of cellulose triacetate, and the acetone-soluble cellulose acetate may contain 20-100% of its weight of effect material.  Specifications 460,955, [Group IV], 687,481, 743,625, 758,442 and 776,346 are referred to.
Patent HK-15696-A (HK)
Title: Direction-determination logic
Inventor: GLEIM GUENTER
IPC: G11B7/085
Filed: 1996-01-25
Abstract: A direction-determination logic is used in compact-disc players to establish in which direction the scanner is travelling across the tracks of the disc after either an intentional jump or an unintentional one caused by a knock, for instance. In order to determine in which direction the scanning light beam is travelling across the disc tracks, the phase difference between a track error signal (TE) and the envelope of the HF signal (HF) which generates the scanning light beam is only evaluated if the speed with which the light beam travels across the tracks is below a given value. The logic of the invention for the determination of the direction of motion of the scanner can be used in compact-disc players, video-disc players, DRAW-disc players and magneto-optical instruments.

Abstract: PURPOSE:To keep a driver from sleepiness by changing the temperature or the speed of air blowed, when detecting the fatigue of the driver. CONSTITUTION:As a safety drive adviser 202 judges that a driver is fatigued and an alarm lamp 206 is lighted, a relay 201 is turned on in linkage and adds a resistor 200 in parallel to a temperature setter 31. Then the resistance value of the temperature setter 31 seen from an electric circuit 2a becomes smaller because of parallel combination of the resistor 200 with the temperature setter 31 and is equivalent to when the temperature setter 31 is moved to a low temperature setting side, and control for lowering room temperature is carried out so as to lower the temperature of air blowed. When an accelerator pedal 203 is stepped in a switch 204 is turned on and a relay 205 works to set the resistance value of the temperature setter 31 to 0, which is equivalent to when the temperature setter 31 sets the lowest temperature; therefore, in order to set the temperature of air blowed at its minimum, an adjusting door 142 is put in a turning movement to close a heater core 41 and a controlling valve 132c is actuated so that the delivery capacity of a compressor 132 is made maximum.
