Abstract: Procédé de fabrication d'un guide d'ondes optique à pertes réduites dans une couche épitaxiale en silicium. Selon un procédé connu de fabrication d'un guide d'ondes optique à pertes réduites dans une couche épitaxiale en silicium d'un composant en silicium à éléments électroniques intégrés dans un substrat en silicium, une couche isolante est agencée entre le substrat en silicium et la couche épitaxiale en silicium. La couche épitaxiale se compose d'un matériau de type "silicium sur l'isolateur", qui est un matériau rare. Afin de pouvoir mettre en oeuvre de façon relativement économique un procédé de fabrication d'un guide d'ondes optique à pertes réduites, on applique une couche épitaxiale en silicium (2) faiblement dopée sur le substrat en silicium (1). On diffuse dans la couche épitaxiale en silicium une substance contenant un élément du groupe IV de la classification périodique des éléments ayant une composante réelle de l'indice de réfraction plus élevée que celle du silicium.

Abstract: Plaquette à circuits flexible pour le montage de circuits intégrés, présentant des bosses sur sa surface postérieure qui pénètrent dans la plaquette pour relier une configuration de câblage de circuits. Les surfaces des bosses peuvent être recouvertes d'une couche métallique de soudure en fonction de la structure desdites bosses.

Inventor: OBATA HIROYUKI
IPC: G03G5/022

Abstract: A data recording medium (2) is manufactured by laminating an electrode (2b) and a recording layer (2a) of a pinene polymer having a molecular weight of 500 ∼ 10,000 on a support (2c). By thermal development, a thermally stable frost image can be produced without causing attenuation of data charge generated on the resin surface. Transmitted or reflected light can be accordingly used for reproduction of the frost image, without provision of a photoconductive layer coloration of which has bad influence. Since voltage impression exposure is made, the degree of uneveness of the frost image changes in accordance with the exposure value. Therefore, a tone wedge effect can be provided and high resolution can be obtained. It is thus possible to produce high-quality and high-fidelity OHP transparencies, microfilms, slide films, and so forth.

Abstract: In a supporting device for the simultaneous coupling of several parallel-arranged fluid connectors, which contains 
 
  - a holding plate (1) having openings (2), which are arranged in at least one straight row, for holding connecting pieces (5) (which are provided with abutments (5W)) of fluid lines (6) and 
  - a securing slide (3), which can be guided displaceably along one sliding direction in the holding plate (1) and has at least one contour (TQi) which can be moved into a position which fixes the connecting pieces (5) in the openings (2), by displacing the securing slide, 
 according to the invention 
 
  - the openings (2) of the holding plate (1) are designed so that they are not round, such that the abutments (5W) of the connecting pieces (5) can be axially fixed in a positively locking manner, at least temporarily, on an edge (2HR) of the respective opening once they have been inserted axially and displaced laterally,
 and 
  - the at least one contour (TQ) fixing the connecting pieces (5) is designed in a straight line parallel to the sliding direction of the securing slide (3), such that the connecting pieces (5) can be fixed laterally within the non-round openings (2) in the position in which their abutments (5W) engage with the edge (2HR), by means of the at least one contour (TQ) of the securing slide (3) which is designed in a straight line and runs, with respect to the edge, on the side of the connecting pieces (5) facing away from said edge. 
 
<??>From this it results that the securing slide can be displaced relative to the holding plate (1) while the connecting pieces (5) remain fixed. This can be used in an advantageous manner for the arrangement of connecting elements for the common mounting of the holding plate (1) and securing slide (3) on a component which is intended to make fluid contact with all the connecting pieces (5) simultaneously, exclusively in the securing slide (3).

IPC: F23Q2/167
Filed: 1991-04-12
Abstract: This disclosure is an improvement for the conventional lighter in parts thereof such as the gas reservoir, the gas control valve, the gas nozzle, and the pressing plate; the prime feature is that two opposite sub-walls are provided in the gas reservoir, being perpendicular to the inner wall thereof; the two opposite sub-walls form a capillary groove to enable a liquid gas to flow upwards by means of capillary effect. 
     The gas control valve has a section of outer threads in the lower part thereof, a seal ring mounted around the neck portion thereof, and a disc portion on the upper part thereof; the disc portion has a ratchet gear, and a round flange which is furnished with a cut of 90 degrees upon the gas control valve being fixedly mounted in a valve seat and the flame adjustment being done. The cap of lighter has a salient piece formed with a punching machine to extend into the cut of the round flange; the salient piece is used to prevent the round flange from rotation. The gas control valve has a cylindrical hole for receiving a gas nozzle, and the lower end of the gas control valve has a valve hole to receive a part of a bi-nail member so as to control the flow of gas. 
     The aforesaid gas nozzle has a neck portion, of which the center has a nozzle outlet; the lower part of the gas nozzle has a smaller diameter to form into a pin portion with a longitudinal groove. The bottom of the pin portion is inserted with a plastic nail; since the plastic nail is shorter than the longitudinal groove, a space is left in the longitudinal groove so as to facilitate a gas to flow into the nozzle outlet. The gas nozzle is inserted in the gas control valve to control the ON/OFF of gas. 
     Under the pressing plate, there is a leaf spring made of plastic material to be molded integrally with the pressing plate; the leaf spring extends into a cylindrical reservoir beside the flint base so as to push the pressing plate upwards and to cause the clamp fork on the front end of the pressing plate to push the gas nozzle downwards in order to have the gas nozzle closed normally. On both sides of the clamp fork, two plastic walls are provided to cover the fire-striking wheel and the gas nozzle within in a given space.

Abstract: A deinking agent for the reclamation of waste paper which comprises one or more of specific compounds is disclosed. Each of the specific compounds used in the present invention, which is obtained by, for example, further esterifying an alkylene oxide adduct of a dibasic acid, is characterized by being excellent in abilities to wash and disperse ink and foaming properties. Further, each is a dibasic acid-series compound and is thus superior to common nonionic surfactants in its ability to aggregate ink. Therefore, these compounds show good performance as a deinking agent. In addition, they are in the form of a liquid and thus can be easily handled, different from, for example, fatty acids.
