Title: Production of stable aqueous hydrolyzable organosilane solutions.
Inventor: AVERY RICHARD W
IPC: C11D1/65
Filed: 1991-11-27
Abstract: A method of improving the stability and broadening the range of pH stability of an aqueous solution of from about 0.001 % to 5 % by weight of a water soluble organosilane containing hydrolyzable groups such as methyltrimethoxysilane, 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride and 3-(trimethoxysilyl)-propylmethyldi(decyl) ammonium chloride by the use of 0.05 % to 10 % by weight of a water soluble organic quaternary ammonium compound having at least one nitrogen-bonded hydrocarbon group of at least 8 carbon atoms and being free of silicon atoms, such as benzalkonium chloride, along with from about 0.5 % to 30 % by weight of at least one surfactant selected from the group consisting of nonionic, amphoteric sarcosine anionic, and cationic surfactants other than the water soluble quaternary ammonium compounds. The pH of the solution can be adjusted to from about 1 to about 13.5 with a suitable acid or base. The resulting stable aqueous solutions are useful for depositing the water soluble organosilane on a variety of substrates to, among other things, serve as coupling agents, waterproofing agents and to render substrates antimicrobial and algicidal depending upon the nature of the organosilane.

Abstract: Dans un appareil d'imgerie utilisant un élément de support rotatif agencé pour porter un élément d'écriture, une source de lumière est ménagée mobile par rapport à l'élément d'écriture afin de projeter un rayon de lumière d'écriture sur l'élément d'écriture et générer ainsi une image. La source de lumière comprend une pluralité de diodes laser et une pluralité de fibres optiques connectant les diodes à une tête d'écriture mobile adjacente à l'élément porteur, les fibres optiques dans la tête d'écriture ayant des extrémités de sortie agencées suivant un réseau linéaire. L'amélioration consiste en un substrat de support sensiblement plan, disposé dans la tête d'écriture et conçu pour supporter les extrémités de sortie des fibres optiques sur une première surface de celui-ci. Ce substrat est pourvu de plusieurs rainures sur ladite première surface, chaque rainure recevant l'extrémité de sortie d'une fibre. Un agencement de focalisation est prévu pour focaliser le rayon d'écriture par rapport à l'élément d'écriture et comprend une diode laser en vue de générer un rayon de focalisation de lumière qui est projeté sur l'élément d'écriture, et une cellule photoélectrique. Une fibre optique de focalisation connecte la diode de focalisation sur la tête d'écriture, l'extrémité de la fibre optique de focalisation au niveau de la tête d'écriture étant supportée sur la surface opposée du substrat par rapport à ladite première surface, sensiblement au centre du réseau linéaire des fibres optiques du faisceau d'écriture. Ainsi, le faisceau de focalisation est projeté sur l'élément d'écriture en avant du faisceau d'écriture et est séparé du faisceau d'écriture lorsqu'il est détecté par la cellule photoélectrique.

Abstract: An ultrasonic motor for stepwise driving a rotor 112, in which the stepping amount of the rotor is made smaller than the interval between nodes of a standing wave, or the stepwise movement of the nodes thereof. An ultrasonic vibration generating circuit 107 includes a circuit 106 to generate a travelling wave used to rotate the rotor 112 and a circuit 105 to generate a standing wave used to stop rotation of the rotor. 
     A power source 101 drives an oscillating circuit 102 whose output is divided in a circuit 103 and supplied to a timing pulse generating circuit 104. The output of circuit 104 is to a switching circuit 108 which controls the selection of input from the ultrasonic vibration generating circuit 107 to output to a piezoelectric vibrator drive circuit 109 which energises a piezoelectric vibrator 110. Ultrasonic vibrations are produced at a vibrator member 111, secured to the vibrator 110 and having a plurality of comb-like projection portions. The rotor 112 has a number of poles which is greater than the number of nodes when the standing wave is generated. The rotor 112 is pressed into engagement with the vibrator member 111 and is subject to rotation by the travelling wave and stopping by the standing wave. The rotor is stopped at a force balanced position, depending on the positions of the poles of the rotor, the positions of the nodes of the standing wave, and the positions of the projection portions of the vibrator member. By properly changing the travelling wave and standing wave, a smaller stepping angle of the rotor than the interval between nodes or the stepwise movement of the nodes may be achieved.
