Patent EP-0654904-A2 (EP)
Inventor: MEYER BRIAN DEAN
IPC: H03K17/0412
Filed: 1994-09-23
Abstract: An optically isolated N-channel MOSFET driver (10) turns on a MOSFET device (72) in response to an optical input signal to drive a load (74). The turn-on time of the MOSFET is enhanced by a current boost circuit (34). As the MOSFET transcends to an on state and delivers current to the load, the voltage across the device diminishes and causes the current boost circuit to become inactive thus reducing to zero the current drain consumed by the current boost circuit. A photovoltaic array (40) maintains the MOSFET operation. An optically isolated SCR (66) is respondent to the absence of a light signal to turn off the MOSFET. Furthermore, the optical decoupling of the SCR, between the gate and source of the MOSFET device, is arranged to provide enhanced noise immunity. A voltage clamping circuit (70) coupled between the gate and source of the MOSFET device provides additional protection to the device from large over voltages.

Abstract: The vibrating plate of invented crystal oscillator, comprised of a rim part, vibrating part surrounded by said rim part with a slit in-between, and a relatively narrow connecting part connecting said vibrating part and said rim part, all of which are made of a same material. 
     Since the relative position of said vibrating part is fixed to said rim part, said vibrating part can never be contacted with said rim part. Furthermore, thicknesses of said vibrating and said connecting part are respectively less than the thickness of rim part, said vibrating part can never be contacted with the casings encasing said vibrating plates. 
     Furthermore, since said vibrating plate is provided with surface electrodes and said connecting part is provided with electrical leads which are extensions of said electrodes, and said vibrating plate is encased in a upper and lower casings respectively provided with a through-hole at a position facing to said electrical lead. 
     A cup-shaped metal lead is fixed in the through-hole, and the bottom of the cup is fixed on the electrical lead facing to the through-hole, and the metal and electrical leads are electrically connected in this case. The metal lead is fabricated by depositing metal particles on the throguh-hole using either an evaporation or supputering method. The current to the electrodes of vibrating part is supplied through the metal leads.

Abstract: An automatic language-determining apparatus automatically determines the particular European language of the text image of a document when the gross script-type is known to be, or is determined to be, an European script-type. A word token generating means generates word tokens from the text image. A feature determining means (30) determines the frequency of appearance of word tokens of the text portion which correspond to predetermined word tokens. A language determining means converts the determined frequency of appearance rates to a point in a new coordinate space, then determines which predetermined region of the new coordinate space the point is closest to, to determine the language of the text portion.

Abstract: Techniques for automatically laying out directed graphs with clusters. The techniques produce pictorial representations of the graphs which are easier to understand, more pleasing, and more compact than those produced by the prior art. The techniques have been added to the well-known DOT system for laying out directed graphs, and include a recursive technique for ranking nodes of the graph, a technique for ordering nodes within ranks which collapses subclusters into skeletons when the nodes within a cluster are ordered, and a technique for positioning the nodes after they have been ranked and ordered which obtains the x coordinates for the nodes by producing an auxiliary graph which is in effect the original graph "turned on its side" and assigning ranks to the nodes in the auxiliary graph.

Abstract: An off-chip driver with regulated supplies compensates for power supply fluctuations. The circuit reduces di/dt noise by providing complementary voltage regulators (34,36) to regulate the high and low supplies to the driver stages (16) such that they see a constant operating voltage regardless of changes in supply voltage, V CC . The circuit uses two push-pull stages (10) which charge and discharge the output load capacitance, C₀. This regulated voltage to the driver stages (16) reduces di/dt noise and provides a constant overdrive voltage, constant gate slew rate, and constant staging delay over a specified external supply voltage range.

Abstract: A recording layer including a recording magnetic domain for recording thereon information is formed. A reproducing layer for reproducing information by projecting thereto a light beam is formed on the recording layer. A non-magnetic intermediate layer for intercepting a magnetic exchange coupling force exerted between the recording layer and the reproducing layer is formed between the recording layer and the reproducing layer. The reproducing layer is arranged such that the width of the stable magnetic domain on the reproducing layer at room temperature is larger than the width of the recording magnetic domain in the recording layer. At a reproducing temperature by the light beam, the width of the stable magnetic domain becomes smaller than the width of the recording magnetic domain, and the information is copied by the leakage magnetic flux of the recording magnetic domain. Depending on whether or not the information transferred to the reproducing layer is reproduced, the effects from other magnetic domain adjacent to the magnetic domain to be reproduced from the reproducing layer can be prevented, thereby enabling a high density recording of information on the recording layer.

Abstract: The invention is embodied in high reliability semiconductor lasers that need not be maintained inside a hermetic enclosure. Such lasers can advantageously be used in a variety of applications, e.g., in optical fiber telecommunications, and in compact disc players. Such "non-hermetic" lasers comprise facet coatings (e.g., 401, 41) that comprise a dielectric layer (e.g., 401, 41) that has very low water saturation value. In preferred embodiments this dielectric layer is SiO x  (1 Z x < 2), deposited by a molecular beam method. Deposition conditions are selected to result in a dense material that is largely free of particulates and blisters, and is substantially impermeable to moisture. Among the deposition conditions is substantially normal beam incidence, and a relatively low deposition rate. Deposition is advantageously carried out under relatively high vacuum conditions. A quantitative method of determining the water level in a SiO x  film is disclosed. The invention is also embodied in articles (e.g., integrated circuits or discrete semiconductor devices) that have a low stress (absolute value less than 90 MPa, even less than 20 MPa) SiO x  layer disposed on a semiconductor body.
