Patent EP-0319571-A1 (EP)
Title: Router for integrated circuits.
Inventor: MCGEHEE RICHARD K
IPC: G06F17/50
Filed: 1988-06-24
Abstract: A method of specification of the routing of signal and planar power nets between terminals of a core module and pads in an array of pads surrounding the core module. The method identifies proximity terminals and cyclic constraints and then routes the signal nets and power nets in separate moat rings that are concentric with the core module. The proximity terminals and any pads involved in cyclic constraints are routed in respective proximity and cyclic moat rings, adjacent the core module and pad array, respectively. Finally, the resulting moat signal nets are promoted within the signal to the next most outwardly adjacent, unoccupied concentric tracks, and then sections of the proximity, signal, power, and cyclic rings are collapsed to the next most radially inward, unoccupied concentric tracks. In a further step, the method of the present invention can route each of the possible orientations of the core module with respect to the array of pads, thereby determining the minimum possible chip area for the desired integrated circuit.

Abstract: A sigma-delta converter including a switching component (313) controlled by a first clock (308) having determined transitions for generating a train of sigma-delta code pulses corresponding to an analog input value. The sigma-­delta includes means (306, 310, 311) for generating a second clock (350) of a same frequency than the first clock and having a negative transition followed after a defined period of time (d2) by a positive transition. The determined transi­tions of the first clock controlling the swithing element occur during said de­fined period of time. There is also included means (305) controlled by the sigma-delta code pulse train and said second clock for generating a train of sigma-delta pulses being insensitive to the mismatch of the rise and fall times of said switching element (313) whereby improving the linearity and the signal-to-noise ration of the converter. The control of the said period of time allows the varying of the energy of the pulses in order to provide pulses train which, when applied to a sigma-delta decoder, provides an analog output value representative but attenuated with respect to the analog input value.

Abstract: The effect of the scattered radiation produced on irradiating a body (K) with X-rays is eliminated by image reconstruction. This is achieved not by using a scattered radiation baffle in front of the detector field (DF), but by applying a solution to the physical problem. The number of scattered X-ray quanta is determined from the transport equation for the X-ray radiation. The detector measurements can consequently be appropriately corrected by a digital filtering and the diffuse proportion of the image is decisively reduced in the image reconstruction. <IMAGE>

Abstract: Tube d'affichage fluorescent destiné à des écrans de grandes dimensions. Ce tube présente une zone élargie sur laquelle tombent les faisceaux d'électrons, et élimine l'effet du champ électrique à proximité de la paroi en verre du tube d'affichage fluorescent (1) sur les faisceaux d'électrons, ce qui permet de positionner les segments de substance luminescente R, V et B à proximité de la paroi latérale périphérique (13) du tube. Par conséquent, la surface photoémettrice est accrue pour obtenir un affichage lumineux. En outre, les distances entre les segments contigus de substance luminescente du terne RVB sur les tubes d'affichage fluorescents contigus (1) sont raccourcies, de même que les distances entre les ternes dans chacun des tubes d'affichage fluorescents (1). Par conséquent, la distance entre les luminophores du terne est réduite globalement dans ce système d'affichage sur grand écran, ce qui contribue à en améliorer la résolution.

Abstract: In a heat-transfer sheet for transferring an image of color material layers (2a, 2b, 2c, 2x) to a transferred material such as cards in accordance with image signals applied by a thermal head to the color material layers, the color material layers are applied only in a specific local area of a substrate film (1) corresponding to an area in which the transferred image of the transferred material should be formed. Therefore, the color material layers do not come into contact with those areas of the transferred material in which the transferred image does not exist and scumming that occurs around the transferred image can be prevented. The color material layers can be saved by disposing them locally. A protective layer which is transferred onto the surface of the image after the heat transfer of the image to the transferred material can be disposed separately on the heat-transfer sheet. This protective layer provides the transferred image with wear resistance and contamination resistance.

Abstract: On propose un procédé et un dispositif pour le traitement de sols contaminés et de matériaux similaires par enlèvement, décontamination et, le cas échéant, remblaiement de la zone du prélèvement avec un sol purifié. Le sol enlevé est séché en broyé dans un broyeur (2, 29, 57) traversé par un flux de gaz chauds et le mélange de matières solides et de gaz ainsi formé est conduit vers un séparateur à cyclone (4, 31, 58) afin de de séparer ses constituants gazeux et solides. Les substances solides subissent un traitement thermique à haute température (6, 32, 60) et une première décontamination se produit à ce stade. Après une nouvelle séparation des phases solides et gazeuses dans un second cyclone (8, 34, 62), les substances solides encore partiellement contaminées sont déposées dans une zone de stockage intermédiaire (9, 35, 63) aménagée en zone de transit et retraitées à des températures sensiblement équivalentes à la température de décontamination. Les gaz rejetés par le broyage-séchage et la décontamination sont exposés à une nouvelle combustion thermique (16, 42, 75) et usilisés au moins en partie dans le processus de décontamination pour économiser l'énergie.

Abstract: A power steering apparatus wherein a heated state of the electric motor is detected without employing any temperature sensor. There are previously stored plural temperature characteristics each representing the relationship between the temperature variation caused per unit time in the electric motor and the load current, which are prepared, for plural motor temperatures or plural differences between the motor temperature and the ambient temperature. A temperature characteristic is selected on the basis of the present predicted motor temperature or the difference between the motor temperature and the ambient temperature. The present load current is detected, and the temperature variation caused per unit time correspondingly to such load current is calculated from the selected temperature characteristic. The unit-time temperature variations thus obtained are integrated with the lapse of time to predict the present motor temperature. Upon rise of the predicted motor temperature beyond a predetermined point, the electric motor is considered to be in a heated state.

Abstract: The specification of the instant invention discloses improvements in methods for making various types of mats of fiberous material. In particular, the improvements relate to methods for making continuous fiber glass strand mats using reciprocating strand feeders and a pro4grammable motion controller to control both the rate of reciprocation and the rate at which strand is deposited from the feeders onto a moving conveyor so as to form mats of uniform density and thickness. Electric servomotors are used to reciprocate the feeders and also deposit strand therefrom. A closed-loop feedback circuit is used to accurately monitor and control the position of the feeders with respect to the conveyor as well as the rate of strand deposition. Methods for using the programmable motion controller described herein can increase the uniformity of needled, resin-impregnated, and uni-directional fiber glass mats.

Abstract: A rotary evaporator has joint-pipe (20) of an evacuated double tube adiabatic structure. It is used, e.g. in a rotary evaporator or used with any evaporating apparatus having a heat-exchanging condensor, and avoids premature cooling and undesirable condensing of the solvent vapor ascending therethrough. Inside the joint-pipe, any reverse flow of the liquefied solvent vapor to a sample flask is effectively prevented, and the solute is brought to complete dryness in an extremely mild conditions. The decrease in the degree of vacuum in the sample flask is also effectively avoided, thus improving the evaporating efficiency and/or concentrating efficiency of the overall apparatus including the sample flask and the pipeline. There is no more local circulation (round trip) of the solvent vapor between the condensor and the recovered-solvent-reservoir through the adapter caused by the reevaporation of the solvent.
