Title: Method of marking rubber goods
Inventor: BRAZIER PETER CHARLES
IPC: B41M1/32
Filed: 1987-12-07
Abstract: A rubber surface, for example the rubber surface of a floor mat having a pile surface and a rubber backing, can be marked in a water-resistant and abrasion-resistant manner by means of a sublimable transfer dye applied in a dry-heat transfer printing process. The resulting marking can be a code of letters and/or numbers and is used to identify the mats. The markings are particularly useful where the mats are periodically collected and cleaned as part of a laundry service.
Patent GB-2207807-A (GB)
Title: Hot electron transistors
Inventor: LONG ADRIAN PETER
IPC: H01L29/76
Filed: 1988-06-10
Abstract: In a method of forming a hot electron transistor, a collector electrode structure (6) is formed on a substrate (1) by molecular beam epitaxy (MBE). Over the collector structure a layer (17) of a doped semiconductor material is formed, also by MBE. At least one metallic base contact region (19,20) is formed in the doped layer (17) by diffusion, and a metallic emitter contact (23) is deposited on the doped layer to form an emitter contact and to form a Schottky barrier at the interface between the emitter contact and the doped layer. A layer (18) of undoped semiconductor material may be formed over the doped layer. The base contact region will then be diffused through the undoped layer and into the doped layer. This method of construction avoids the difficulty of very accurate etching away layers to reveal the base region, which has previously been encountered. <IMAGE>

Patent GB-892181-A (GB)
Abstract: 892,181. Seaming non-metallic sheet material. SHABRAM, L. F. April 15, 1959 [April 18, 1958], No. 12761/59. Class 42 (1). [Also in Groups XI and XVII] Apparatus for continuously forming edgeunited laminar articles, comprises a continuous flexible backing belt, means for superimposing a plurality of layers of heat alterable plastic sheet material on the belt, means for tensioning the sheet material, heated die means supported at a cylindrical surface, means for rotating the cylindrical surface and means for wrapping the belt and sheet material around a major portion of said surface for pressing the material between the belt and the surface and heat sealing the material in contact with the die means. In the embodiment shown, motor 12 drives endless belts 18 and 28, the former driving the die roller 26, whilst the latter drives the winding reel 32 and trim-winding reel 36. A paper sheet 62, underlying or overlying double plastic sheets 66 is threaded around pulley 22 and between belt 18 and the surface of die roll 26. As the plastic passes adjacent the periphery of the die roll, electrically-heated wires on the surface of the die roll and arranged in the desired configuration, melt the plastic, severing it and at the same time sealing the severed edges. A string or narrow tape may be interposed between the roll surface and the plastic adjacent one end of the roll so that there remains a continuous plastic strip the length of the sheet. This ties together the finished articles. As the articles leave the die roll they pass over idler roll 108 and are wound up on reel 32. The trim which may remain is guided over rolls 104/106 and roll 108 on to reel 34. An endless belt carrying a plurality of brushes is arranged to be driven across the top of the die roll so that the brushes clean the surface of the roll. In a second embodiment for the manufacture of plastic bags the cutting and sealing wires are arranged in slots across the peripheral surface of the die roll and the wires are arranged to be brought to the surface of the roll in controlled sequence by solenoid and cam mechanism, working in conjunction with an electric eye which scans the sheets for printed insignia and ensures the cutting and sealing operation occurring at the right position. In a third embodiment the die roll is expandable for producing articles of variable pattern and dimensions.

Title: Method of forming boron doped silicon layers in semiconductor devices using higher order silanes
Inventor: SHIOZAWA JUNICHI
IPC: H01L21/02
Filed: 1992-08-19
Abstract: A method of forming a semiconductor device includes depositing a boron doped amorphous silicon layer on a substrate having many steps, projections or cavities, by thermal decomposition of a higher order silane gas eg Si2H6orSi3H8 and diborane gas at 150 DEG -450 DEG C. The diborane gas may be supplied to the substrate in a reaction limited. At least one of O2, N2O, NH3, N2 or NF3 may be added to the reactants. The thermal decomposition may be carried out at 0.01-0.2 Torr. An insulator layer may first be formed on substrate which is etched to form a contact hole prior to deposition of the doped silicon. Alternatively after first forming a conductor element the doped silicon layer may be etched, an insulating layer applied, a contact hole formed in the insulating film to expose the first conductor element, the contact hole refilled and a second conductor element formed thereon. A dynamic RAM may be produced by forming a trench on a substrate, forming a MOSFET having source/drain region and a switching transistor on the substrate, then forming a plate electrode through a capacitor insulating layer formed of the doped silicon, prior to annealing to a polysilicon layer.
