Title: Système et procédé destiné à la fixation des montants d'une barrière dans le sol
Inventor: NIEDERKOFLER HANNES
IPC: E01F15/04
Filed: 2017-11-15
Abstract: La présente invention concerne l'installation de barrières de sécurité routière (également appelées "glissières de sécurité" ci-après). Lesdites barrières constituent un élément très important de toute route, et elles présentent une fonction cruciale pour la sécurité. En effet, en plus de délimiter visiblement les bords de la route, elles réduisent considérablement le risque d'accidents impliquant des sorties de route de véhicules. Cette dernière fonction de sécurité implique que la glissière de sécurité installée reçoive une certification afin de garantir des exigences mécaniques appropriées. Cependant, les conditions d'installation réelles dépendent des différents types de sol et, dans de nombreux cas, les normes de sécurité ne sont pas satisfaites en raison de l'installation. Le sous-système pour la fixation des glissières de sécurité au niveau de la base selon l'invention permet de fixer les montants desdites glissières de sécurité au sol de manière à permettre d'obtenir une étanchéité d'installation homogène dans différents types (ou différentes structures) du sol lui-même, et il est capable d'assurer la conformité avec les conditions de certification. De plus, un tel sous-système de fixation au niveau de la base des glissières de sécurité permet de fixer les montants desdites glissières de sécurité au sol tout en présentant une vitesse d'installation et des coûts durables. Ces objectifs sont atteints au moyen d'un sous-système de fixation au sol de montants de barrières de bord de route (c'est-à-dire les éléments verticaux d'une glissière de sécurité) comprenant un boîtier composé d'un matériau résistant à la corrosion (aluminium, inox, acier revêtu de zinc, matériaux composites, polymère, plastique etc.) approprié pour être fixé au sol. Et ledit boîtier, lorsqu'il est enterré (c'est-à-dire installé dans le sol) maintient une ouverture dans sa face supérieure, de manière à être également approprié pour accueillir la partie souterraine d'un montant d'une barrière côté route, qui est insérée à l'intérieur dudit boîtier à travers ladite ouverture qui est formée de manière à être adaptée à l'étendue.

IPC: B60R21/015
Filed: 2004-08-02
Abstract: An activation control apparatus controls activation of an airbag unit (30). An electronic control unit (12) detects a floor deceleration Gf and front decelerations GI, Gr from signals output from a floor sensor (14) and front sensors (16, 18). Also, the electronic control unit (12) calculates a velocity change Vn from the floor deceleration Gf, and determines the severity of a collision. Further, the electronic control unit (12) determines the state of a symmetric flag FRG through comparison between the front decelerations GI, Gr and the value of a front determination map boundary, serving as a front threshold variation pattern and through comparison between the floor deceleration Gf and the value of a low or high map boundary, serving as an activation threshold variation pattern. Then, on the basis of results of the severity determination and the state of the symmetric flag FRG, the electronic control unit (12) determines a delay time in relation to the activation of the airbag unit (30). An airbag (36) is expanded and deployed on the basis of the delay time.

Title: Two-dimensional photonic crystal with air bridge structure and manufacturing method for the crystal
Inventor: HATSUDA RANKO
IPC: G02B6/122
Filed: 2004-08-27
Abstract: A two-dimensional photonic crystal, wherein a clad layer (32) is disposed on the lower side of a slab layer (31), and areas (35) having refraction factors different from that of the slab layer (31) are cyclically disposed in the slab layer (31). Also, the crystal comprises a spot defect (36) formed by the missing of a part of the areas (35). The spot defect (36) forms a resonator resonating light of a specified wavelength. An air bridge space (37) is formed in the specified area of the clad layer (32) to face the spot defect (36). Since the slab layer (31) is supported by the clad layer (32) in those areas other than the area in which the air bridge space (37) is formed, the mechanical strength of the two-dimensional photonic crystal is high. Since the air bridge space (37) is present under the spot defect (36), light can be easily entrapped in the spot defect (36) due to a difference in refraction factor between the slab layer (31) and air. Accordingly, the spot defect (36) forms the resonator having high performance.

Abstract: A method of multiple-process reaction in which a large number (N) of samples are reacted under the same reaction conditions, wherein the samples each includes as a reaction solvent a solution whose phase state reversibly changes between a two-phase solution state and a homogeneous solution state at a given temperature. In the method, the samples are successively treated in the following steps: (A) a vessel heating continuation step in which many reaction vessels are simultaneously heated and are kept at a given temperature, (B) a sample heating step in which the samples are separately introduced into the heated reaction vessels and the two-phase solution is regulated so as to have a given temperature, (C) a reaction step in which each sample heated to the given temperature is stirred to obtain a homogeneous solution, which is held for a given time, and (D) a cooling step in which after the lapse of a given time period, each homogeneous solution is cooled, without cooling the reaction vessel, to obtain a two-phase solution in the reaction vessel. The method of multiple-process reaction, which is for reacting a two-phase solution changing in phase state with temperature changes, enables many samples to undergo chemical processes under the same conditions by means of one apparatus.
