Abstract: In a freely oscillating flyback switching power supply having a semiconductor switching element (V11), which can be controlled by a control device (IC), and having an RCD circuit (R6, C5, V5) for limiting the peak voltage of overshoots when the semiconductor switching element (V11) is switched off, a first input terminal (2) of the control device (IC) is connected to the junction point of an RC element (R30, C4) for the application of a signal simulating the primary current. This RC element (R30, C4) is connected with its capacitor (4) to reference potential and with its resistor (R30) to the junction point (P1) of the half-wave rectifier (V5) belonging to the RCD circuit, the capacitor (C5) and the resistor (R6). Advantage: As soon as the resistor (R6) in the RCD circuit (R6, C5, V5) and hence a limitation of the peak voltage breaks down, the control device (IC) automatically controls the switch-on duration of the semiconductor switching element (V11) back. The semiconductor switching element (V11) is thus effectively protected against destruction as a result of overheating. <IMAGE>

Abstract: L'invention concerne les explosifs et, plus particulièrement, un procédé et un appareil permettant de faire détoner des explosifs secondaires. Les détonateurs de type à claquement, bien connus à ce jour, présentent le désavantage de nécessiter des plaques de claquement épaisses ainsi que des pièces lourdes usinées avec précision par les détonateurs. On décrit ici un procédé permettant de faire détoner des explosifs secondaires, et un détonateur pour exercer ledit procédé, dans lequel une charge primaire microfine (25) d'un matériau de détonation et de déflagration faciles est mise à feu dans une chambre (23, 28), dont une paroi mince (24) la sépare des explosifs secondaires à faire détoner. Lorsque la pression dans la chambre (23, 28) atteint une valeur prédéterminée, ladite paroi mince (24) se sépare de la chambre (23, 28), la chute de pression sensibilise les éléments détonants de la charge primaire (25) qui détonent et poussent, en l'accélérant, la paroi mince (24) contre les explosifs secondaires (22) de manière à produire une détonation auto-entretenue.

Abstract: In the case of such a position-measuring device for measuring the relative position of objects, an embodiment of a measure (M1) has on its first side (F1a) a first graduation (T1a) for a first measuring direction (X) and, on its second side (F1b), a second graduation (T1b) for a second measuring direction (Y), whose crossed graduation marks extend over the entire measurement length (LY, LX) of the measuring direction (Y, X) at right angles to its associated measuring direction (X, Y). A scanning device (A1) has two scanning units (A1a, A1b) which scan the two graduations (T1a, T1b) in order to obtain position-measurement values for the two measuring directions (X, Y). Since the scanning points of the two scanning units (A1a, A1b) are opposite one another, measurement inaccuracies caused by guidance errors of the two objects are prevented. <IMAGE>

Filed: 1991-11-27
Abstract: There are described methods of extracting a virus genome from a sample derived from a living body as well as detecting the genome by measuring a product due to the genome and amplified through a polymerase chain reaction. A genomic RNA or DNA of the virus is extracted through a treatment by a proteinase in the presence of a non-ionic surface active agent. In case of the genome of RNA virus, the RNA is converted into its cDNA with use of a reverse transcriptase, prior to the polymerase chain reaction. These all reactions containing the polymerase chain reaction are able to carry out with use of only one reaction tube. A possibly existing product in a reaction solution obtained after the final polymerase chain reaction is reacted with a fluorescent substance to check the presence or absence of the product by radiating UV rays. The reaction solution can be controlled in its pH in the range of 10 to 12.
