Patent EP-0350178-A2 (EP)
Inventor: UENO MASAJI INTELLECTUAL PROPE
IPC: H03K17/06
Filed: 1989-06-20
Abstract: An output circuit provides a high voltage output signal in response to a low voltage input signal. The output circuit includes a pull-up transistor (19) for raising the output signal substantially to a power source voltage level (VCC) and a pull-down transistor (21) responsive to the input signal for lowering the output signal substantially to the ground level (VSS). The pull-up transistor is biased by a self-bias circuit (14) triggered by a prescribed level of a control signal VG. The self-bias circuit continues to bias the pull-up MOS transistor in order to bring the output signal level to the high voltage level, even if the prescribed level period of the control signal terminates.

Title: Loop communication network
Inventor: HARRIS JOHN
IPC: H04L12/10
Filed: 1990-02-12
Abstract: A communication network is provided for transmitting data in a hostile electromagnetic environment. Master and slave units are coupled to a data path by transformer coupling. The slave units can be turned on by applying a DC voltage between transformer taps at the master, and detecting the voltage at corresponding taps at the slave. Separate pairs of conductors are used to carry signals transmitted by the master and signals transmitted by the slave. The conductors form a closed loop data path enabling the master to selectively transmit data either in a clockwise or counterclockwise direction around the loop. Data may also be received by the master either clockwise or counterclockwise around the loop. In this manner, the master can communicate with the slaves even if there is a break in the data path.

Abstract: The output enable (OE) cutoff driver gate (Q5,Q8) of a cutoff driver circuit is coupled to receive OE signals of high and low potential and hold an ECL logic gate (Q6,Q7) in the cutoff state in response to one of the high and low OE signals. An OE signal driver circuit provides the OE signals of high and low potential to the OE cutoff driver gate (Q5,Q8). The OE cutoff driver current sink for sinking current from the OE cutoff driver gate is provided by a current switch circuit (QD,QE) for switching sinking current on and off in response to current switch signals of high and low potential in phase with the OE signals. The current switch circuit (QA-QE) switches on sinking current when the OE cutoff driver gate (Q5,Q8) is holding the ECL logic gate in the cutoff state. The current switch circuit (QA-QE) switches off sinking current for reducing power dissipation when the ECL logic gate (Q5-Q8) is out of the cutoff state. The current switch circuit (QA-QE) is provided by a current mirror circuit (QD,QE). A first emitter follower output buffer (Q3) delivers OE signals from an OE input gate (Q1,Q2) to the OE cutoff driver gate (Q5,Q8). A second emitter follower output buffer (QA) delivers current switch signals from the OE input gate (Q1,Q2) to the current mirror circuit (QD,QE) in phase with the OE signals.

Abstract: Die Erfindung betrifft Verfahren, bei denen durch ein chemisch inertes und nicht festes Medium Druck auf eine Halbleiteroberfläche (0) ausgeübt wird,wobei zum Beispiel mit Hilfe einer Abdichtung (6a) verhindert wird, daß sich ein Gegendruck in einer Zwischenschicht (2) aufbaut. Eine Verbindung zwischen dem Halbleiter (3) und dem Substrat (1) erfolgt durch Drucksintern oder durch Diffusionsschweißen. Eine Berührung zwischen einem aktivem, inneren Bereich des Halbleiters und einem Preßkolben kann dadurch vermieden werden, daß der Preßkolben einen erhabenen und ringförmigen äußeren Bereich zur Abdichtung besitzt und der eigentliche Preßdruck durch das Druckmedium über eine im Preßkolben befindliche Bohrung bewirkt wird. Dieser erhabene Rand zur Abdichtung kann sich, anstatt auf dem Preßkolben, auch auf dem Halbleiter befinden. Wird ein Halbleiterbauelement mit einer Kunststoffschmelze umspritzt, so kann diese Kunststoffschmelze selbst als Druckmedium dienen. <IMAGE>

Abstract: The invention relates to a method and an apparatus for making dimensionally stable pressed articles from pulverulent compositions, in particular metal powder, on a press in a compression mould with at least one upper die and at least one lower die, in which the pressing dies in the final pressing position are moved to predetermined theoretical positions, and, during the pressing, the progression of the compressive force of at least one of the dies is recorded as a function of the travel and compared in each case with a predetermined, travel-dependent tolerance range for the compressive force. In order to provide a method and an apparatus which permit even closer tolerances as regards the dimensional accuracy of the pressed articles and at the same time further reduce the risk of defective production, it is proposed that, if the tolerance range is exceeded, the theoretical position of the die in question in the final pressing position is modified so that the height of the pressed article in the final pressing position is reduced by an amount which corresponds to the increased upward expansion of the pressed article after its unmoulding, associated with the higher final pressing force, and the reverse procedure is adopted if the compressive force falls below the tolerance range.

Abstract: Hydrated sodium silicate particles can be expanded by heat to form thin-walled bubbles that can be broken, neutralized, washed and dried to provide hydrated silica flakes. These flakes (30) can be mixed with non-swelling sorptive particles (36) such as TLC grade silica and used to make chromatographic articles. One such article (32) is a composite of a poly(tetrafluoroethylene) fibril matrix (34) in which those particles and hydrated or fired silica flakes are enmeshed. The hydrated silica flakes can be fired to a refractory state and then incorporated into protective coatings to enhance their resistance to abrasion while also better protecting the coated substrates from corrosion.
