Abstract: ABSTRACT OF THE DISCLOSURE A method  for  manufacturing  a  phosphor  screen used in a color CRT takes the steps of multilayering a red  phosphor  layer,  a  green  phosphor  layer,  a  blue phosphor layer, and a non-luminescent layer being laid between the adjacent color phosphor layer, cutting the multilayered  block  into  filmy  pieces  toward  the thickness, adhering or pressurizing the filmy cut pieces on a glass plate for front panel of the color CRT, and burning the cut pieces. This method makes it possible to efficiently  manufacture  a  high-definition  and  high-resolution  color  phosphor  screen  and  form  fine  RGB stripes. This method, thus, may apply to a small-sized CRT about which the realization of the high-definition and  high-resolution  color  phosphor  screen  has  been difficult.

Inventor: INOUE YOSHIHIRO
IPC: H05K5/00
Filed: 1991-08-15
Abstract: A locking groove extending in the horizontal direction is formed approximately at the center of a front surface of a cartridge.  A power switch is turned on/off in response to an operation of a slide switch.  When the power switch is turned on by the slide switch, a lock plate rotates in response to the operation of the slide switch.  At this time, a projecting portion provided on one side of the lock plate is fit in the locking groove.          Consequently, simultaneously with the turning on/off the power, the cartridge is locked so as not to be ejected.

Abstract: L'invention concerne un procédé et un appareil pour améliorer la qualité de restitution de l'ambiance acoustique d'une scène sonore dans un système de reproduction stéréophonique comprenant deux ensembles de transducteurs électroacoustiques de reproduction disposés à distance l'un de l'autre pour restituer simultanément des informations sonores contenues dans deux signaux d'audiofréquence qu'ils reçoivent par l'intermédiaire d'un canal droit et d'un canal gauche et qui correspondent respectivement à une partie droite et à une partie gauche de la scène sonore. Selon l'invention, on découpe en zones successives et contiguës chacun des spectres de fréquence des canaux droit et gauche avant d'appliquer les signaux d'audiofréquence aux transducteurs acoustiques des deux ensembles de transducteurs, le nombre de zones d'un des spectres étant égal au nombre de zones de l'autre spectre, et on reproduit simultanément les informations sonores des deux spectres à raison d'une zone sur deux dans chacun d'eux et de manière telle que, lorsqu'une zone de l'un des spectres est reproduite acoustiquement, la zone correspondante de l'autre spectre ne l'est pas, les deux spectres étant ainsi reproduits acoustiquement en simultanéité mais d'une façon alternée et complémentaire. L'invention permet de restituer plus exactement l'ambiance sonore de la scène telle qu'elle existe dans les conditions naturelles, lors de son enregistrement.

Title: Gas-blast circuit breaker
Inventor: BLATTER JOHANNES
IPC: H01H33/82
Filed: 1992-03-27
Abstract: In a gas-blast circuit breaker, compressed gas is directed through a movable contact maker into a blow-out space, the latter being delimited by a cylinder and a piston which is operatively associated with the movable contact maker. The piston comprises inlet openings which are releasably closed by means of a valve body. At a neck or collar of the piston there is displaceably mounted an actuating element, the latter being reciprocatingly movable between a lower first lock-in position and an upper second lock-in position. The actuating element comprises a nose or lug which, during the closing operation, abuts against an upper stop face or surface, whereby the actuating element is brought into the lower first lock-in position. The valve body thereby moves into the closed position thereof. Towards the end of the opening stroke, a shaft associated with the actuating element comes to bear upon a lower stop face or surface, so that the actuating element is brought back to the upper second lock-in position thereof, whereby the valve body is returned to and retained in its open position. The blow-out space is thus connected with the ambient space during the closing operation and again separated from the ambient space prior to the opening or tripping operation. The driving mechanism of the circuit breaker is assisted during the interruption of relatively high-amperage currents and no additional driving effort is required of the driving mechanism during the closing operation and the interruption of relatively low-amperage currents. The gas-blast circuit breaker thus gets by with a driving mechanism of relatively low operating power.

Title: Movable industrial plant to dry into powder different liquids
Inventor: MAYOLO DANIEL A
IPC: F02B1/04
Filed: 1992-04-08
Abstract: ABSTRACT           MOVABLE INDUSTRIAL PLANT TO DRY INTO POWDER DIFFERENT LIQUIDS         One of the ways to carry out this invention can be obtained by constructing a series of elements properly arranged and assembled. It is effecient as regards space, function, economy , and durability that assembled on wheels, following the regulations required for chassis measures, can achieve what can be done in an installed plant.  This movable industrial plant to dry into powder several liquids is basically made up of an evaporator, pulverization drier, boiler, vacuum and centrifugal pumps, pipes and transport tubes, separators of small particles, liquid separators, motive power, liquid tanks, electrical system, etc. This industrial plant can dry milk into powder, cream, soya bean milk, fruit juice, soluble coffee, blood, plasma, glands, soap powder, sewer waste, etc. This small industrial plant has the advantage of moving to the place where the raw material is found, which can be dried into powder at the same time it is produced.  Th bacterial and chemical contamination in the food products is reduced to zero. Moreover, the organoleptical original characteristics are preserved.  Operative costs are reduced to values that reach zero.  The following is possible: 1)  The arrangement and reappearance of new milking factories in areas very different from the traditional ones.  2)  Due to the low operative costs the utilization of very important proteins that are normally lost is possible.  For example, blood, plasma, whey, etc. 3)  The solution to contamination problems wither chemical or bacteriological for  example drying into powder sewer waste which later on will have commercial value; drying into powder chemical substances which are not degradable or are toxic, that otherwise would contaminate rivers, lakes, seas, etc., at a low cost in the place of origine and at the same time.
