Patent EP-0482411-A1 (EP)
Title: Cigarette lighter
Inventor: SHOZO FUJITA
IPC: A47L9/26
Filed: 1991-10-07
Abstract: A cigarette lighter with high operability and safety is proposed. According to this lighter, when a lock member is rotated in a lighting operation, the lock member is automatically moved to a position to allow the movement of an operating member upon reception of an upward pressure from a spring. When the operating member is moved after the lighting operation, the lock member is moved to a position to inhibit the movement of the operating member upon reception of a rotary biasing force from the spring, thus automatically locking a lighting operation of the operating member while the lighter is not used.

Abstract: Polymeric layers have optically nonlinear or anisotropic characteristics in regions (so-called patterns) selectively that are delimited in terms of area and arbitrarily shaped. These regions are sharply delimited with respect to areas having a centrosymmetrical or isotropic structure, or areas having other optically nonlinear or anisotropic characteristics. The polymeric layer has optically nonlinear and/or mesogenic side chains which are crosslinked in an area-selective fashion by the influence of light, the regions having optically nonlinear or anisotropic characteristics being subjected during the crosslinking to the influence of orientation fields or orientation forces. The transitions between the optically different regions are typically restricted to approximately 1  mu m. <IMAGE>

Abstract: The present invention proposes a convertor for the guided propagation mode of electromagnetic waves, including a transition structure and means of coupling between this structure and a waveguide able to propagate the mode resulting from the mode conversion, and also comprising means of coupling between the transition structure and a waveguide or a source of microwave electromagnetic energy. According to a significant characteristic of the invention, the said transition structure comprises l waveguides (g1, g2, ... gl), l being an integer number greater than 1, chosen as a function of the TElm mode to be converted (m also being an integer number greater than or equal to 1); these l guides being coupled at their two ends, by coupling holes, respectively to a source of microwave electromagnetic energy or to a guide (G1) in which a TElm wave of complex structure propagates, on the one hand, and on the other hand to a waveguide (G2) able to propagate the mode resulting from the conversion. According to another significant characteristic of the invention, the transition structure comprising l waveguides is coupled directly onto the output cavity of a microwave tube; and, according to another characteristic, the said microwave tube is a gyrotron. <IMAGE>

Abstract: Dans un procédé d'exécution d'une mesure de résonnance de plasmon de surface, un faisceau (12) de rayonnement électromagnétique est dirigé à travers une partie (4) laissant passer ledit rayonnement, sur la surface (5a) d'une couche de matériau (5) ayant été mise en contact avec un matériau à contrôler, sur sa face opposée (5b). On utilise la modification de l'intensité du rayonnement réfléchi, provoquée par le phénomène de résonnance, pour analyser le matériau à contrôler. La couche est formée d'un matériau catalytique, par exemple, du palladium, possédant une partie réelle négative de la constante diélectrique à la longueur d'ondes utilisée du rayonnement électromagnétique et pouvant catalyser les réactions chimiques auxquelles participe le matériau à contrôler. On effectue la mesure à une longueur d'ondes et à un angle d'incidence (o) du rayonnement sur la surface (5a) appropriés pour détecter, dans l'intensité du rayonnement réfléchi, une modification résultant de la concentration de matériau accumulée sur la face opposée (5b) du matériau à cause des propriétés catalytiques.
