摘要:
An intake barrel (10) connected to an intake pipe of an internal combustion engine is provided therein with a venturi member (12). Openings (22,16) are formed in the wall of the intake barrel (10) at the upstream and donwstream sides of the venturi member (12). A bypass passage forming member (28) provided with a groove (26) of a length greater than the distance between said openings (22,16) is fixed to the outside of the intake barrel (10). A bypass passage (34) is formed by these openings (22, 16) and the groove (26). A spacer (32) is interposed between the intake barrel (10) and the bypass passage forming member (28). The cross-sectional area of the bypass passage (34) can be varied by varying the thickness of the spacer (32).

Gegenstand der Erfindung ist ein Stecker (1) zum Abdecken von Schaltkontakten in z.B. Anschlußleisten von fernsprechtechnischen Geräten, der aus einem oberen Ziehkopf (4), einem verbreiterten mittleren Stützteil (2) sowie zwei unteren Federzungen (5) und einem zwischen diesen angeordneten Führungssteg (3) besteht. Der Stecker ist einstückig ausgeführt und dient zum Abdecken bzw. Trennen von LSA-PLUS-Schaltkontakten in Anschlußleisten, wobei zur Vermeidung von Verschmutzungen dieser Schaltkontakte deren Kontaktstellen von Bauteilen des Steckers nicht berührt werden.
摘要:
A system for controlling an exhaust gasdriven supercharger used in an internal combustion engine for an automotive vehicle includes an exhaust gas bypass passage (48) connecting between selected portions of the exhaust gas conduit upstream and downstream of a turbine (44) of the supercharger (42), and an exhaust bypass valve (50) disposed midway of the exhaust gas bypass passage (48) for controlling the quantity of engine exhaust gases. In the supercharger control system, an actuator (52) responsive to a digital control signal is employed for actuating the exhaust bypass valve (50). A microcomputer (100) calculates the opening of the exhaust bypass valve (50) so that the supercharged air pressure may not exceed the critical point giving rise to knocking, and such a digital control output signal is applied to energize the actuator (52) so that the supercharged air pressure can be controlled with highest efficiency over a wide operation range of the engine.

Die Kabelanschlußvorrichtung weist, um gleichzeitig Kabelendverschluß zu sein, Schutz gegen äußere Einflüsse zu bieten, mit ihrem Mantel Kurzschlußströme aufnehmen zu können und das Rangieren von schweren Kabeln in flachen Kabelräumen zu ermöglichen, ein abgewinkeltes Metallgehäuse (1) auf, in dem ein elastischer Isolierstoff (2) und aus elastischen Werkstoffen hergestellte Elektroden (3) angeordnet sind, die zur Potentialsteuerung dienen. Vorzugsweise sind im elektrischen Schutzbereich der Elektroden (3) und im Metallmantel (1a) Kompressionsräume (4, 4') vorgesehen.
摘要:
A multiple access digital communications system comprises a plurality of remotely located terminals coupled to a communications bus including a pair of oppositely directed, unidirectional signal paths (10, 12) and a unidirectional path coupler (14) for transferring signals from the inbound path (10) to the outbound path (12). To send a message from one terminal to another desired terminal, a corresponding bus interface unit (20A) coupled to both the inbound and outbound paths (10, 12) is adapted to perform an rf. carrier sensing operation to determine as to whether or not any other subscriber is transmitting on the inbound path (10). If no carrier is detected, the bus interface unit (20A) confirms this determination by first beginning to transmit a message packet and then monitoring the outbound path (12) during a collision window. If the transmitted message is received intact within this collision window, the bus interface unit (20A) may transmit any remaining portion of its message packet on the inbound path (10).
摘要:
A control system employing a microcomputer, which controls the starting operation of a spark ignition type engine provided with a fuel injection system. The control system is loaded with, at least, contact information of an ignition switch (90) for connecting an ignition device (58) to a power supply (88) and a starter switch (92) for connecting a starter motor (76) to the power supply (88), and an output signal of a temperature sensor (56) for detecting the temperature of cooling water (84) of the engine. In case where the cooling water temperature is not higher than a predetermined temperature, a fuel pump (32) which supplies pressurized fuel to an injector (12) of the fuel injection system is started simultaneously with the closure of the ignition switch (90), and this fuel pump (32) is stopped during the operation of the starter motor (76).
摘要:
The invention relates to a semiconductor strain gauge comprising four piezoresistive elements (10,12,14,16) which include a low impurity concentration diffused portion and a heavily-doped diffused portion. The resistance values of the two low impurity concentration diffused portions opposite to one another are greater than the resistance values of the other two low impurity concentration portions. The resistances of the heavily-doped diffused portions are so selected that the resistances of the piezoresistive elements (10,12,14,16) are equal.

Die Erfindung bezieht sich auf eine Einrichtung zur elektrischen Stimulation des Herzens mit einem elektronischen Impulserzeuger (2) und einer Reizelektrode. Ziel und Aufgabe der Erfindung ist es, eine handliche, an beliebigen Orten anwendbare und von einem Arzt ohne kardiologische Spezialausbildung bedienbare Einrichtung zur Stimulation des Herzens, insbesondere in Notfallstituationen, zu schaffen, die auch bei Änderung der Patientenimpedanz und Absinken der Versorgungsspannung elektrische Impulse hinreichend großer Ausgangsspannung und Stromstärke sowie genügender Formenauigkeit und zeitlicher Konstanz über eine Reizelektrode, insbesondere eine Ösophagusefektrode, zur Verfügung stellt und darüber hinaus eine hohe Patientensicherheit bei Ausfällen von Bauelementen bietet. Erreicht wird dies erfindungsgemäß dadurch, daß ein Gleichspannungswandler (3) vorgesehen ist, der eingangsseitig an eine Spannungsquelle (1) geschaltet ist, die gegebenenfalls auch zur Speisung des Impulserzeugers (2) dient und daß der Impulserzeuger (2) auf einen elektronischen Schalter (4) arbeitet, der für die Zeitdauer des Stimulations-impulses die Ausgangsspannung des Gleichspannungswandlers (3) an die Reizelektrode führt.
摘要:
Fuel control method is disclosed, in which data used to control the amount of fuel supply in the previous cycle is corrected by an output of an 0 2 sensor (21) in a current cycle, and added to or subtracted from the corrected data value is a difference between a value derived from data stored in a map based on an output of a vacuum sensor (19) and an engine rotation speed in the previous cycle and a value derived from the data stored in the map based on an output of the vacuum sensor and an engine rotation speed in the current cycle, and the sum or difference is used as current control data.
摘要:
A CRT hard copy apparatus for sampling a picture signal from a CRT display and for recording the sampled signal on a recording paper. In order to obtain a suitable CRT hard copy for both kinds of CRT display in which the number of characters per screen is large and small, the CRT hard copy apparatus is constructed to include a first sampling means (22', 23') for sampling in the horizontal scanning direction a video signal on a CRT display of small number of characters per screen, and a second sampling means (24,25) for sampling in the vertical direction to the horizontal scanning lines a video signal on a CRT display of large number of characters per screen. In addition, a switching means is provided to actuate only the first sampling means upon horizontal scanning and both the first and second sampling means upon vertical scanning.
