La chambre (21) comprend une électrode de détection (26) espacée de l'étincelle. Des particules à grande mobilité (principalement des électrons) sont observées presque en même temps que l'étincelle alors que les particules ioniques à faible mobilité sont diffusées plus lentement après l'étincelle. Grâce à un gaz porteur inerte (12), des molécules métastables à haute énergie sont dispersées et libèrent de l'énergie après l'étincelle. L'énergie est obtenue de l'électrode (27) durant, immédiatement, après ou longtemps après l'étincelle. Une autre émission est obtenue à partir du spectre observé durant et après l'étincelle.

Title: Method for reducing the number of bits in a binary word representing a series of addresses
Inventor: GOUBERT JOZEF A O
IPC: G06F13/00
Filed: 1992-12-22
Abstract: ABSTRACT OF THE DISCLOSURE           The method for reducing the number of bits in a binary word which represents a series of addresses, called initial addresses, is characterized in that they include at least a first step which consists successively in extracting from each initial address at least one bit with a fixed rank; forming an address called the selection address from this bit or bits; extracting from each initial address a series  of  bits  using  a  format,  as  a  function  of  the selection address; forming with this series of bits a binary word called the first relative address;  and adding this first relative address to an address called the prede-termined basic address associated with the format selected to determine this first relative address.  To predetermine a  basic  address  associated with  the  one  in  the  first formats, the method consists in considering successively the first formats; taking 0 for the basic address associated with  the  first  format  considered  from  the  said first formats; and taking for the value of each basic address associated respectively with the other first formats, the sum  of:    the  last  basic  address  determined  for  the previously  considered  first  formats,  and  the  maximum relative address value which can be obtained using the last previously considered first format incremented by one unit.

Filed: 1993-04-19
Abstract: A known photoelectric sensor is utilized for optically detecting  the  presence  of  a  tape  cassette  in  a  loading commencement position to produce an electrical driving signal.          Responsive to the driving signal, an electric loading motor is activated to cause a loading arm to swing from one angular position to another angular position.  Rotary movement of the loading motor is translated into a pivotal swinging movement of the loading arm by a unitary linkage lever.  The linkage lever carries a light beam interrupter piece which may cut off the light beam projected by the photoelectric sensor to enable the latter to generate the electrical driving signal.  The linkage lever also carries an arm locking finger adapted to lock the loading arm in a loading completion position.   A reversible speed reduction gadget is employed in operatively coupling the linkage lever to the loading motor.

Abstract: Abstract of the Disclosure A method of creating a weld joint between two metal members (B1, B2).  The members have coincidentally configured abutting edges (El, E2), first surfaces (lA, lB) which are adjacent to and on one side of the edges, and second surfaces (2A, 2B) which are adjacent to and on the other side of the edges.  The method includes chamfering the corners of the respective edges and first surfaces to create a generally V-shaped groove (4) between the first surfaces.  A gasket (5) of weld filler material is placed between the edges.  The gasket is held between the edges and extends both into the groove and outwardly beyond the second surfaces.  The groove is next filled with additional weld filler material (7), and the gasket is then melted and fused with this additional material.  The portion of the gasket extending outwardly beyond the respective second surfaces is melted and fused with the edges to form a smooth, continuous surface (8) with the second surfaces.  Forming of this latter smooth, continuous surface is accomplished without the use of any additional weld filler material.
