Abstract: A data communication system between a plurality of data terminals comprises of a terminal apparatus to which a plurality of data terminals are coupled in a star structure through pair lines. The terminal apparatus has a plurality of cable driver circuits and a plurality of cable receiver circuits each coupled with a related data terminal through said pair lines, and outputs of cable receivers and inputs of cable drivers are coupled commonly to a single common line. Thus, data from a data terminal is transmitted to another data terminal through a terminal apparatus. A communication control apparatus is installed close to a data terminal. The communication control apparatus has a data terminal transmit data only when other terminals do not transmit data in order to prevent collision of data in the terminal apparatus. The use of pair lines between data terminals and the common terminal apparatus, the simple structure of the terminal apparatus which has only cable drivers and cable receivers coupled together, and a collision control performed in a communication control apparatus which is positioned close to a data terminal are features of the present invention.

Abstract: In an axial flow turbine, such as an exhaust gas turbine, in order to prevent the driving gas from escaping through the slits (9) formed in an outer nozzle ring (8) of integral type construction, which divide said ring into several segments so as to facilitate differential thermal expansion, and thus by-passing the regular flow of the gas through the nozzle structure, filler metals (15) are located in the slits. 
     Preferably, the radial depth of the filler metals is shorter than the slits, and they are fixed e.g. by fixing bolts (17) and tongues (16) provided on the filler metals, so as not to protrude beyond the inner diameter of the outer nozzle ring.

Abstract: A percussion-actuated instantaneous or delay detonator transmits a detonation from a first length of low-energy detonating cord (LEDC) transversely positioned adjacent the detonator's percussion-responsive end to a U-shaped segment of a second length of LEDC held with its apex against the base-charge end of the detonator and the arms of the U extending away from the detonator. A directional connector for connecting a U-shaped segment of detonating cord adjacent each end of the detonator has identifiable donor- and receiver-cord-housing sections, e.g., the receiver-cord-housing section has the shape of the head, and the donor-cord-housing section the shape of the butt, of an arrow. A connector adapted to hold receiver LEDC and high-energy detonating cord (HEDC) segments is internally configured to receive nested U-shaped segments of LEDC and HEDC only when the LEDC is adjacent the base-charge end of the detonator.

Abstract: The present invention relates to a device for sensing specified conditions in a fluid medium. According to an aspect of the invention the device is in the form of a wave detector for use in a swimming pool and includes an electrical circuit provided with an alert member and a power source for operating the alert member. The circuit is normally open between two spaced apart electrodes which substantially eliminates all power drain from the source. When the electrodes are closed by the waves in the pool the alert member is activated with the circuit further being provided with a normally conductive control member which changes to a nonconductive state for opening the circuit to deactivate the alert member in and which automatically returns to the conductive state to reset the circuit for further activation of the alert member.

Abstract: High speed printing can be attained without loss of printing quality. The amount of energy to be supplied to each heating resistor in the next printing cycle is determined by the amount of energy which was supplied to it during the previous cycle of printing, as well as by the density of picture data to be printed. Other information which may be taken into account in adjusting the amount of energy supplied to the heating resistors includes the amount of energy previously supplied to adjacent resistors and the duration of the printing cycle (where this is variable).

Abstract: An oxide-isolated RAM and PROM process disclosed wherein a RAM circuit includes a lateral PNP transistor formed in the same island of silicon material as a vertical NPN device and further wherein contact is made to the base of the lateral PNP and to the collector of the vertical NPN through a buried contact region accessed through a sink region formed in an adjacent island of semiconductor material. A field implantation beneath the isolation oxide avoids implanting impurity along the sidewalls of the semiconductor material adjacent the field oxidation and therefore provides both vertical and lateral isolation from one silicon island to another. Substantial reductions in sink sizes and cell sizes are obtained by eliminating the field diffusions from the sidewalls of the semiconductor islands. The lateral PNP transistor serves as an active load for a memory circuit construction using the structure of this invention. The process also can be used to manufacture PROMS from vertical NPN transistors. An LV CEO  implant is used to increase the breakdown voltage of each vertical transistor from its collector-to-emitter thereby allowing junction avalanching of selected emitter base junctions to program selected PROMs in the array even though the programming voltage is only a few volts beneath the breakdown voltage of the oxide isolated structure.

Abstract: Bei einem trockenen, abgestimmten Kreisel sind als Drehmomenterzeuger zwei Paare von Spulen 44 mit ferromagnetischem Kern 46 vorgesehen, die auf einen ferromagnetischen Kreiselrotor 36 wirken. Die Spulen 44 sind jeweils um 90° gegeneinander winkelversetzt. Gegenüberliegende Spulen 44 sind gegensinnig von einem Gleichstromsignal beaufschlagt und erzeugen ein Drehmoment. Dafür sind wegen des Kerns 46 nur geringe Ströme erforderlich. Die Spulen 44 sind auf Gebern 48 abgestützt, die auf die Reaktionskräfte ansprechen. Die Geber 48 enthalten Schwingquarze und liefern ein Drehmomentsignal in Form einer Frequenz, was die digitale Signalverarbeitung erleichtert. Die Paare von Spulen 44 sind gleichzeitig von Wechselstrom beaufschlagt und wirken durch die Veränderung der Induktivitäten auch als Lageabgriffe. Das Abgriffsignal des einen Paares von Spulen 44 steuert das Gleichstromsignal für das andere Paar und umgekehrt.

Abstract: In operating a display device incorporating a matrix addressed smectic cell, a strobing pulse is applied to each row electrode in turn while data pulses are applied in parallel to the column electrodes. The data pulse voltage excursion is less than the minimum voltage V T  required to switch the cell. For the entry of complete rows the strobing voltage excursion is made larger than twice V r  for fast data entry. For entry of rows in successive segments (e.g. for single character entry) the strobing voltage is of longer duration and is less than twice V T  so that successive strobing pulses applied to a single line cannot give rise to spurious switching of unselected pixels.
