Abstract: L'invention concerne un procédé de réalisation d'un transistor HBT non planaire comprenant d'abord la formation de l'émetteur, la gravure du dispositif autour de l'émetteur jusqu'au niveau de la couche de base, l'ouverture d'une région pour le contact de collecteur, l'émetteur étant protégé, puis la réalisation du contact de base par autoalignement sur l'émetteur et le collecteur. Ce procédé met en oeuvre des étapes d'inversion de profil durant lesquelles on utilise le dépôt successif de deux couches diélectriques de matériaux différents dont la première a une épaisseur uniforme et la seconde une épaisseur non uniforme et qui sont gravées avec des vitesses différentes pour faire apparaître des motifs choisis. L'invention permet en outre de réaliser de manière concomitante des résistances enterrées. Le dispositif obtenu est particulièrement compact et performant et le procédé ne nécessite qu'un nombre d'étapes de masquage très limité et réalisables avec une résolution non critique. Application : réduction de la surface des circuits intégrés incluant des transistors HBT et des résistances

Abstract: A controlled suspension for a wheeled vehicle includes a damper 20 between the vehicle body 10 and wheel 11, the damper 20 being switchable, at a frequency at least twice the resonant wheel vibration frequency, between a first mode of operation producing a high damping force and a second mode of operation having a low damping force. A controller 15 repeatedly derives from vehicle operating variables an actuator force to be applied between the body 10 and wheel 11 in order to produce a desired suspension behaviour, determines whether that force would result in active or dissipative suspension power. The controller 15 further stores a threshold actuator valve and controls the damper 20 for each derivation so that (1) the damper 20 operates in its second mode of operation when the actuator force would produce active lower, (2) the damper 20 operates in its first mode of operation when the actuator force exceeds the threshold and would produce dissipative power, and (3) the damper 20 operates in its second mode of operation when the actuator force is less than the threshold and would produce dissipative power. The controller can also be used with active suspensions.

Abstract: A process for production of chlorine dioxide which is substantially free of by product chlorine. Chlorine-dioxide is produced from an alkali metal chlorate, a mineral acid and a reducing agent such as methanol in a reaction medium maintained at an acid normality of less than 9 and with a high chlorate molarity. The process is carried out in the substantial absence of additional chloride ion being fed to the process. It has been found that increasing the chlorate concentration at a given acid normality reduces the amount of chloride in the reaction medium thus reducing the amount of chlorine by-product. The process is carried out in a vessel operated under subatmospheric pressure, whereby water is evaporated and withdrawn together with chlorine dioxide and the alkali metal salt of the mineral acid is crystallized within the reaction vessel and withdrawn therefrom. According to the invention, high production rates with high efficiency of chlorine dioxide can be achieved while producing essentially no chlorine by-product.

Abstract: This describes a differential amplifier for producing an output current proportional to the differential input voltage regardless of the common-mode input voltage and comprises two identical voltage networks (15, 16) coupled between differential voltage inputs (11, 12) and to common differential current outputs (13, 14) and a common bias circuit (19). The described transmission line circuit operates as a transmission line receiver circuit with a high degree of common-mode rejection that will work in a high input signal voltage environment and in which both true and complement outputs can be developed such that their signal responses are additive and their common-mode responses subtractive. The circuit thus converts the input voltage to an input current while isolating the sensing circuit from common-mode input voltages which may be in excess of the breakdown voltage of the individual components of the circuit and the power supplies powering up the sensing circuit.

Abstract: A speech detection apparatus capable of reliably detecting speech segments in audio signals regardless of the levels of the input audio signals and the background noises. In the apparatus, a parameter of input audio signals is calculated frame by frame, and then compared with a threshold in order to judge each input frame as one of a speech segment and a noise segment, while the parameters of the input frames which are judged as the noise segments are stored in the buffer (109) and the threshold is updated according to the parameters stored in the buffer. The apparatus may utilize a transformed parameter obtained from the parameter, in which a difference between speech and noise is emphasized, and noise standard patterns constructed from the parameters of the input frames pre-estimated as noise segments.

Abstract: The two computer programs are used for operating the computer arrangement (8). An associated source version of the two computer programs is in each case generated at different times in a central processing unit and converted by means of a computer arrangement of the latter into the associated computer program of the device. All bytes of the computer program not yet changed are stored in a random-access memory (17). Of the content of the changed computer program, only all changed bytes are transferred from the central processing unit to the device, supplemented by information items with regard to the addresses of the changed bytes. The changed bytes are stored at their respective addresses, also transmitted, in the random-access memory (17) where, together with the bytes of the computer program which have remained unchanged and already exist in the random-access memory (17), they form the changed computer program. The computer arrangement (8) also contains a modem (9), a series/parallel converter (10), a central processor (11), two more random-access memories (12, 13), a change-over switch (14), a non-volatile memory (16) and various bus connections (15, 18, 19). The method avoids inadmissibly long transmission times and prevents the overview of the various program variants in operation and the current status of the program documentation from being lost. <IMAGE>

Abstract: A magnetically operated pressure control valve includes an electromagnetic coil (14) having a central passage extending axially through the coil. A moveable armature (18) is axially disposed in the coil passage to be magnetically attracted to a pole piece when the coil is energized. An armature spring (20) biases the armature in a first position when the coil is not energized. A valve body (16) is stationarily located in the valve housing and has two conduits (54,56) therein. Movement of the armature controls fluid flow in the two conduits to control fluid flow between a supply port (26) and a control port, and the control port and an exhaust port (50). Wave washer springs (22,23) are located at opposite ends of the armature between the armature and the valve housing to resiliently absorb kinetic energy from movement of the armature, to reduce impact stress between the armature and housing, and to prevent a vacuum lock between the armature and housing due to their flat surfaces and the fluid in the valve.

Abstract: Improved electroerosion recording media can be prepared by utilizing, on top of a polyester, paper, or metal substrate, a polyvinylbutyral polymer cross-linked with a mixed phenol-tert-butylphenol formaldehyde cross-linking agent as a base layer, and an erodible metallic layer sufficiently thin to be erodible in response to current pulses delivered by a stylus of an electroerosion printer. In a preferred embodiment, the polymeric layer further contains silica. The recording medium may also be top coated with a lubricating agent. The formulation provides excellent adhesion of the conductive layer, and allows the thickness of the aluminum to be increased up to 75%, resulting in an optical density (with aluminum as the metallic layer) of up to 3.5.
