Title: Détecteur de champ magnétique ou électrique, à structure semi-conductrice à effet de champ
Inventor: VINAL ALBERT WATSON
IPC: H01L43/00
Filed: 1978-06-22
Abstract: - Detection de champs magnétiques ou électriques au moyen de détecteurs semi-conducteurs à effet de champ. - Le fonctionnement des détecteurs selon l'invention est basé sur la modulation des limites des régions d'appauvrissement délimitant le canal de conduction (4) qui relie une source (5) à des drains (6) formés dans un substrat semi-conducteur (1). Un signal de sortie accru est obtenu en réduisant la largeur (W) du canal (4), afin d'éliminer les porteurs de charge en excès que l'on trouve normalement dans les dispositifs à canaux larges et en prévoyant des zones d'appauvrissement constituant une fraction importante de la largeur (W). Le rapport entre la largeur non appauvrie (Wv) et la largeur (W) est choisi entre 0 et 0,98. - Détecteurs applicables notamment à la lecture de bandes magnétiques.

Abstract: In the repair of PWR type nuclear steam generators using a remote tooling system, it is necessary to install a tubesheet indexer on the tubesheet (28) in a known location. The remote docking device (200) is a device for facilitating this operation. It comprises a support plate (202) with locking devices (204) mounted theron. The locking devices are capable of being inserted into the tubesheet for suspending the support plate therefrom. A vertical member is attached to the support plate with an attachment mechanism (222) attached to the vertical member. A remonte access manipulator (52) is capable of being attached to the attachment mechanism so that the vertical member can position the remote access manipulator so that the remote access manipulator can be initially attached to the tubesheet in a well defined manner.

Abstract: A spin tuned magnetron includes a spinner (3) which interacts with a magnetron cavity to modulate its frequency of oscillation. The spinner runs in bearings (8, 9) around a shaft (7). The lives of the bearings are a controlling factor in the life of the magnetron.The outer races (OR) are fixed in position relative to each other and to the spinner by spacers (13, 14) and a spring (15) arranged between an abutment (11) and a circlip (12) on the spinner. The inner races (IR) are arranged to be moveable relative to each other and to the shaft by virtue of spacers (10) and (17), a spring (16) between the inner races, and a further spring (18). A pole-piece nose (4) is arranged to be screwed down on the shaft to compress the springs (16) and (18) to provide a desired amount of axial float on the spinner. By setting the axial float the bearing load can be shared as desired and thus increase the lives of the bearings.

Abstract: A test method and a test device for carrying out this test method for DC current sources such as accumulators and batteries is disclosed which permits an unambiguous detection of the state of the test specimen by a single test process and without additional charging of the DC current source (10) (test specimen) to be tested, it being indicated at the same time whether the test specimen's discharging or its physical state (storage capacity) is responsible for a "bad state" of the test specimen. For this purpose the alternating current internal resistance (RS) and the open-circuit voltage (UB) of the test specimen (10) are measured and by coupling the measured values of the open-circuit voltage UB on the one hand and of the internal resistance Rs on the other in mutually assigned characteristic functional logical operations of the open-circuit voltage as a function of the ampere-hour capacity [UB = f (Ah)] or of the alternating current internal resistance as a function of the ampere-hour capacity [RS = f (Ah)] for in each case different physical states (storage capacity) of a DC source of the same type as the test specimen (10), a separate piece of information relating to the charge state on the one hand and to the storage capacity on the other is obtained. <IMAGE>

Abstract: Befestigerstreifen (4), bei denen Nägel, Schrauben und andere Befestiger (5) durch biegsame Haltegurte (6) miteinander verbunden sind, werden als endlose Streifen auf Collatoren gefertigt und in gleiche Abschnitte unterteilt. Zum Aufwickeln dieser Abschnitte zu spiraligen Rollen (106) ist eine Aufwickelvorrichtung vorgesehen, die sich an den Collator anschließt und die die Befestigerstreifen (4) selbsttätig aufwickelt. Dazu ist neben zwei parallelen Führungsschienen (9, 10) ein um eine senkrechte Achse (66 - 66) drehbarer Wickeldorn (54) angeordnet, dessen Haltevorrichtung (73) das Ende des von den Führungsschienen (9, 10) freigegebenen Befestigerstreifen (4) erfasst und somit das Aufwickeln auf den sich drehenden Wickeldorn (54) veranlasst. Nach Beendigung des Aufwickelvorgangs schwenkt der Wickeldorn (54) selbsttätig um 180° und legt die Rolle (106) auf ein Förderband (105), das sie einer Verpackungsstation zuführt. An die Stelle von Wickeldorn (54) ist gleichzeitig ein zweiter Wickeldorn (55) getreten, der jetzt den Aufwickelvorgang übernimmt. Es wird somit jeweils gleichzeitig eine Rolle (106) gewickelt und eine zweite Rolle (106) abgelegt, so daß ein kontinuierliches Aufwickeln mit hoher Leistung ermöglicht wird.

Abstract: The present invention relates to a method and apparatus for producing gas-liquid dispersions in which a motionless mixing device is used to replace or operate in conjunction with a gas sparge ring in an impeller agitator system. 
     In one embodiment, gas and liquid are fed through conduits (16, 18, 20, 22) containing associated motionless mixers (24, 26, 28, 30) to predisperse the two phases. The dispersion is injected into the bottom of a tank (11) containing an impeller agitator (12) which maintains the dispersion for a time sufficient for mass transfer to occur. Significantly less power is required for the impeller agitator (12) to maintain the dispersion produced by the motionless mixers (24, 26, 28, 30) than is required to produce an equivalent level of dispersion with an impeller agitator operating with a gas sparge ring alone.
