Title: Error variance processing equipment for display device
Inventor: ONODERA JUNICHI
IPC: G09G3/28
Filed: 1995-10-05
Granted: 2004-01-06
Abstract: Coupled to an error variance circuit 11 is an emission luminance characteristic acquisition circuit 20 that counts up, at a display number counter 21, the display number in the single or plural frames of the respective bits of image data by the counters, M in number, corresponding to said bits, then solves for display area percentage (Sk) dividing, at a display area percentage operation part 22, the display dot number as counted at a display number counter 21, by total dot number, and acquires the luminance deviation characteristic for each bit by means of an emission luminance deviation characteristic measuring part 24. The luminance deviation thus obtained is renewed for each frame and transferred to the error variance circuit 11, and processed for error variance on the basis of the emission luminance characteristic to be output at PDP. At low level, on the other hand, the luminance deviation is rendered either fixed type luminance deviation or emission luminance level more or less higher than the actual one to reduce the diffusion noise particularly at the low level image portion thereby obtaining a more natural image.

Title: Integrated dual-function catheter system for balloon angioplasty and stent delivery
Inventor: FISCHELL ROBERT E
IPC: A61F2/06
Filed: 1995-11-24
Granted: 2007-08-07
Abstract: An integrated catheter system utilizes a balloon angioplasty catheter placed through a central passageway of a stent delivery catheter to enable balloon angioplasty and stent delivery to be accomplished with a single device. The integrated catheter system is able to perform dilatation of an arterial stenosis, placement of the stent at the site of the stenosis and then the angioplasty catheter balloon can be used to further embed the stent into the arterial wall. Balloon angioplasty, stent placement and stent embedding into the arterial wall are all accomplished while the catheter's angioplasty balloon remains situated at the site of the stenosis. A conically-shaped distal portion of the stent delivery catheter allows stent placement over the deflated balloon after balloon angioplasty even when intimal dissection causes an intimal flap to be pushed inwardly against the deflated balloon. A proximal portion of the integrated catheter system employs longitudinal motion constraining spacers to prevent the stent from being inadvertently positioned beyond the distal end of the balloon. The balloon of the balloon angioplasty catheter can be readily advanced through tortuous coronary arteries because the distal end of the stent delivery catheter can be placed back by 0.5 to 20 cm from the balloon's proximal end during insertion. Thus, the stiffness of the stent and the stent delivery catheter do not add stiffness to the distal portion of the balloon angioplasty catheter, which stiffness can prevent catheter advancement through such tortuous vessels.

Abstract: In this combustion gas control device, an electromechanical control is provided for automatically controlling the supply of the gas to the pilot burner when it is being ignited and subsequently to the main burner. The device has a main chamber, a pilot chamber and an outlet chamber. A spring-biassed valve is provided between the main chamber and the pilot chamber to close communication between the main chamber and pilot and outlet chambers. The spring-biassed valve is opened when a solenoid is actuated to allow gas from the main chamber to flow into the pilot chamber to the pilot outlet for lighting the pilot light. A diaphragm cover is provided between the pilot chamber and outlet chamber while the pilot is lighted to prevent gas from entering the outlet chamber. After the pilot has been lighted the spring-biassed valve is maintained opened by an electromagnetic mechanism while the solenoid is deenergized so as to open the diaphragm cover whereby gas flows to the pilot light as well as the outlet of the device to the burner.

Abstract: A frequency divider 1 on the transmitting side divides the frequency of a clock signal of period T by 8, generates a pulse signal P2 of pulse width 4T and duty ratio 50%, and outputs the result to a shift register 2. The shift register 2 generates pulse signals P3-1, P3-2, P3-3, and P3-4 by giving delays 0, T, 2T, and 3T to the pulse signal P2, and sends them to transmission lines 101, 102, 103, and 104, respectively.  Edge detectors 3-1, 3-2, 3-3, and 3-4 on the receiving side detect respectively the leading edges and the trailing edges of the pulse signals P3-1, P3-2, P3-3, and P3-4, and output edge detection signals P4-1, P4-2, P4-3, and P4-4.          An OR gate 4 combines these edge detection signals.          A clock regenerator 5 generates a regenerated signal P6 having the frequency equal to that of the clock signal P1 based on the combined edge detection signal P5.

Abstract: La présente invention concerne des oligomères et co-oligomères imide de masse moléculaire contrôlée contenant des groupes phényléthynyl pendants (PEPI) et dont les extrémités sont coiffées par des groupes non réactifs ou phényléthynyl, lesquels oligomères et co-oligomères résultent de la cyclodéshydratation de précurseurs oligomères ou co-oligomères contenant des groupes phényléthynyl pendants et dont les extrémités sont coiffées par des groupes non réactifs ou phényléthynyl. Les oligomères ou co-oligomères amide acides terminés par des amines résultent de la réaction de dianhydride(s) avec un excédent de diamine(s) et des groupes phényléthynyl pendants contenant une diamine, à la suite de quoi leurs extrémités sont coiffées par un anhydride phtalique phényléthynyl ou un anhydride monofonctionnel. Les oligomères et co-oligomères amide acides à terminaison anhydride résultent de la réaction de diamine(s) et de groupe(s) phényléthynyl pendant(s) contenant une diamine, à la suite de quoi leurs extrémités sont coiffées par un amide phényléthynyl ou un amide monofonctionnel. Les polymérisations se conduisent dans des solvants aprotiques polaires tels que le N-méthyl-2-pyrrolidinone et le N,N-diméthylacétamide sous atmosphère d'azote à température ambiante. Les oligomères et co-oligomères amide acides subissent ensuite une cyclodéshydratation thermique ou chimique aboutissant aux oligomères correspondants. Les polymères et copolymères obtenus à partir de ces matériaux présentent une combinaison unique et inattendue de propriétés, et notamment des températures élevées de transition vitreuse après durcissement, une meilleure tenue des propriétés mécaniques de la résine pure et de l'adhésif armés de fibres de carbone à des températures pouvant atteindre 204  DEG C sous atmosphère humide, sans que cela n'affecte par comparaison avec des matériaux similaires, le comportement du flux en fusion et son aptitude au traitement. Ces matériaux conviennent particulièrement à l'utilisation comme adhésifs, revêtements, films, moulages et matrices composites.
