IPC: G11B7/013
Filed: 1987-09-10
Abstract: Method of pulse-mode driving of a semi-conductor laser, driving device for a semi-conductor laser and laser-writing apparatus provided with such a driving device. 
     A semi-conductor laser (60) is driven by first driving the laser in the LED region with a pedestal current pulse from a first current source (41) and by superposing thereon an information current pulse from a second current source (51) after current stabilization. Due to this two-stage drive switching transients can be reduced so that shorter pulses are possible and unnecessary power dissipation between the information pulses is avoided which contributes to the lifetime of the semi-conductor laser.

Abstract: The memory interface mechanism according to the invention is driven from the memory controller side. It comprises lines which are shared by the memory user devices 1 and 2 and lines which are specific to the memory user devices. The shared lines are the address and data bus lines 20,22, the byte select lines 24 the data and address clock lines 26 and 24 and the last operation line 30. The specific lines are request lines 11 and 12, address user indicator and data user indicator lines 15,17;16,18. 
     A user initiates a memory operation by activating its request line, then it waits for the activation by the memory interface control circuit 5 for the activation of the address and data user indicator lines 15 and 17. The user controls the address and data transfer count and ends the transfer by activating the last operation line 30. Then it waits for the deactivation by the memory controller of the address and data user indicator lines to present a new request, if any. 
     Thus the memory transfer is memory driven, which allows to take fully advantage of the page mode facility of the memory. The memory operations may be pipelined since servicing a request from a user may be started before servicing the request from the the previous selected user is ended.

Abstract: Un moteur composé comprend un moteur volumétrique (100) tel qu'un moteur diesel à piston rotatif ou alternatif, lequel est relié à un groupe turbine/turbocompresseur sous forme d'un moteur à turbocombustion (102) doté d'une turbine (138) à puissance libre. Les gaz d'échappement du moteur volumétrique passent à travers une conduite (122) et parviennent à la chambre de combustion (16) du moteur à turbocombustion pour faciliter l'entraînement de sa turbine (134), laquelle entraîne le turbocompresseur (106) qui à son tour suralimente le moteur volumétrique (100) à travers une conduite (108). Cette dernière comporte une soupape (109) permettant d'empêcher sélectivement la distribution d'air de suralimentation au moteur volumétrique (100) de sorte que l'on peut faire marcher le moteur à turbocombustion tandis que le moteur volumétrique est arrêté. Afin d'assurer une bonne expulsion des produits de combustion résiduaires du moteur volumétrique (100) ainsi qu'une bonne harmonie entre les caractéristiques de compression et de détente du moteur à turbocompression (102) et du moteur volumétrique, la conduite (108) d'air de suralimentation distribue ce dernier au moteur volumétrique à une première pression plus élevée, et la canalisation (122) d'échappement des gaz de combustion évacue ces derniers vers la chambre de combustion (116) à une seconde pression plus faible. Sont également décrits des procédés d'utilisation des moteurs combinés.

Title: Process and apparatus for isolating endocrine islets from a donor organ, and use of the islets in the treatment of metabolic diseases
Inventor: HUBER WALTER DR
IPC: A61K35/39
Filed: 1988-04-07
Abstract: A process and an apparatus for isolating endocrine islets from a donor organ, for example from a pancreas, and the use of the isolated islets are described. In this process, the donor organ is artificially perfused with a mixed blood substance during a perfusion phase and then immersed in collagenase fluid until the fibre material separates during a dissolution or digestion phase until a homogeneous fragment suspension is formed. The fragment suspension is centrifuged to isolate a sediment from exocrine cell material and endocrine cells, so that in an islet isolation phase the dead endocrine cell contents can be separated from the live endocrine islets. The atraumatically isolated islets can be transplanted or injected for the resumption of the normal metabolic function of an organ. <IMAGE>

Abstract: Particulate, active-oxygen compounds, especially sodium percarbonate, tend to cake during storage, which makes it more difficult to handle them. The invention reduces this caking tendency while the active-oxygen content remains essentially unchanged. The method of achieving this comprises bringing the active-oxygen compound in contact with such an amount of an aqueous solution containing one or more phosphonic acid compounds capable of chelate complex formation that the weight ratio of active-oxygen compound to phosphonic acid compound is 100:0.1 to 100:10, preferably 100:1 to 100:3, and subsequent drying. Sodium percarbonate is used in particular as active-oxygen compound and 1-hydroxyethane-1,1-diphosphonic acid as a 3 to 30% by weight aqueous solution is used as phosphonic acid compound. Sodium percarbonate wet salt is preferably washed with this solution, freed of excess solution and dried. Percarbonate treated in this manner hardly tends to cake at all and exhibits a greater active-oxygen stability.

Abstract: A heating element (2) comprises an electrically resistive track intended to be formed on an electrically insulative substrate (4). A heating unit (10) comprises a heating element (12) and a temperature sensor (14) on a substrate (11), the sensor (14) comprising an electrically resistive track. The track (2,14) consists of a thick film having in the temperature range of from 0°C to 550°C a temperature coefficient of resistance in excess of 0.006 per degree C. The thick film includes a metal and a glass in such proportions as to provide a suitable resistivity and a thermal expansion coefficient to match that of an electrically insulative substrate to which the track is to be applied and to permit adhesion of the track to the substrate. 
     The considerable variation of the resistance of the track with temperature provides advantages in both of the aforementioned applications.

Abstract: A printer uses a ribbon (5), the ink of which is distributed in a series of monochrome sections of the same length and arranged in periodic colour sequences. The length of worn ribbon of each of the sections of a finished series of the used region of the ribbon (5) and located at the boundary with the unused region of the ribbon (5) is memorised. Before the printing of a monochrome line, a length of new ribbon at least equal to the length of the line to be printed and of the colour of this line is first located among the sections of the finished series and then among the sections of the unused region of the ribbon (5). The ribbon (5) is then driven in one direction or the other in order to use the length of new ribbon thus determined for the printing of the line. The invention allows a substantial saving of ribbon, for example in data-transmission or word-processing printers. <IMAGE>
