Patent EP-0410564-A2 (EP)
Inventor: WEISS KEITH DAREN
IPC: C08G77/08
Filed: 1990-06-06
Abstract: The present invention provides a relatively simple synthesis procedure for the formation of silane hydrolyzate compositions of the formula       
 where R is hydrogen or a methyl group, n is an integer greater than about 8 and x is a number between 0 and 2. The hydrolyzate compositions are metastable in solvent solution, but become insoluble after coating on a substrate. The resins are useful as planarizing coatings for substrates such as electronic devices and can be ceramified by subjecting them to an oxidizing atmosphere at a temperature of between about 100 to 1000°C. to form ceramic or ceramic-like coatings on such substrates.

Abstract: Integrated-circuit devices are provided with conductive paths or links which, by laser irradiation or electric current pulsing, can be severed or fused. In the interest of ease of fusing, preferred links have locally reduced thickness as achieved, e.g., by employing two steps of layer deposition and etching as follows: first, a layer (11) of conductor material is deposited on a dielectric surface, and locally reduced in thickness by etching at one or several points selected for fusing, and, second, a further layer (12) of conductor material is deposited, and then etched to produce a desired conductive path passing through such points.

Title: Motor brake circuit for use in a magnetic disk drive system
Inventor: PALM WILLIAM A
IPC: G11B19/22
Filed: 1990-10-26
Abstract: The invention provides apparatus and a method for use in a storage system for braking a storage disk (12) driven by a spindle drive motor (16) with a coil (20A, 20B, 20C). The invention includes trigger means (34, 38) for detecting the back EMF generated in the coil when there is a loss of power and for actuating means (48 to 52, 94 to 98, 132) for electrically shorting the coil when the back EMF falls below a pre-determined level. This level is selected to be large enough so that the rate of rotation of the magnetic disk is sufficient for a magnetic head of the system to "fly" over the surface of the disk, but small enough so that surge currents in the drive spindle motor will not damage the coil.

Abstract: This invention relates to an Erbium-doped fiber amplifier having multiple stages (12,14) of amplification for providing enhanced performance. More specifically, optical means (20,28) is located intermediate first and second stages of doped optical amplifying fibers adapted to receive a pump signal at a pump wavelength where the optical means is adapted to modify the net gain characteristics of the multi-stage amplifier. Presently, all known Erbium-doped fiber amplifiers utilize relatively simple single stage amplifiers which support required ancillary optically passive components such as isolators, filters, pump multiplexers, power monitors and the like at either end of the amplifier. This requirement of having the passive optical element at an end of the optical amplifier not only lends to relatively stringent design and fabrication tolerances for a high performance optical amplifier, but it restricts the design of the Erbium-doped fiber amplifier to an embodiment which prevents exploitation of the various unique properties of the Erbium-doped fiber amplifier.

Abstract: A semiconductor device of band-to-band tunneling type including a silicon substrate, a first gate electrode formed by a highly doped surface region of the silicon substrate, a first silicon oxide film formed on a surface of the surface region, a silicon thin film formed on the first silicon oxide film, a second silicon oxide film formed on a surface of the thin silicon film, and a second gate electrode formed by a metal film applied on a surface of the second silicon oxide film. In the thin silicon film, there are formed P and N type regions side by side to constitute a PN junction. When a gate bias voltage is applied across the first and second gate electrodes, a band bend having a large height and inclination in a direction perpendicular to the thin silicon film is produced in the depletion region in the vicinity of the PN junction. Minority carriers brought up from the valence band into the conduction band by tunneling due to the band bend are conducted through the PN junction under the influence of a reverse bias voltage applied across the PN junction. The band bend can be made large at will by increasing the gate bias voltage, so that it is possible to obtain a large tunneling current.

Abstract: In a rolling mill comprising upper and lower work rolls (1,2) crossed each other to perform strip crown control, a straight line (10,14) connecting the center (12) of an operation side screwdown screw (8a) and the center (13) of a drive side screwdown screw (8b) is inclined relative to a line (7) perpendicular to the rolling direction. A cross angle ϑ to be controlled is changed in opposite plus and minus directions about the straight line (10;14) connecting both the screwdown centers (12;13). A large extent of strip crown control can be achieved with a smaller cross deviation than usual in the prior art, thereby permitting omission of an equalizer beam. Further, change in the extent by which strip crown is varied upon control with respect to the cross angle becomes substantially linear and hence control is more easily conducted. Since the cross angle 2ϑ between the two work rolls is larger than 2°, the transition temperature is not changed and uniformity in quality can be ensured.
