摘要:
A packing for use in chromatography which comprises a cyclic amino-substituted silane compound having the formula (I): ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are the same or different and are each an alkyl having 1 to 5 carbon atoms, an alkoxy having 1 to 3 carbon atoms, hydroxy or a halogen atom in which at least one of R.sup.1, R.sup.2 and R.sup.3 are an alkoxy group or a halogen atom; R.sup.4 is .omega.-piperidino, .omega.-piperazino or .omega.-morpholino group which is optionally substituted by a straight chain or branched chain lower alkyl group; n is an integer of from 2 to 10, said compound being grafted onto an inorganic carrier having hydroxyl group on its surface, and a method for separating water soluble organic compounds by chromatography using said packing.
摘要:
The composition of the present invention is curable by active energy ray. It is a mixture including a coupling agent, an active energy ray-curable compound and water. A glass article will show improved mechanical strength if it is coated with the composition of the present invention and irradiated with active energy ray to cure the coating.

A method for improving mechanical strength of a glass article includes coating an active energy ray-curable composition of a silane coupling agent, a curable compound and water on the glass article, and then curing with irradiated active energy ray.
摘要:
A fuel delivery system of a machine capable of efficiently feeding fuel, where a time of feeding fuel to a construction machine is estimated based on operation information of the construction machine. Based on position information of the construction machine acquired by position information acquiring means and estimated time of feeding fuel, a delivery schedule, which has a short moving distance and capable of delivering and feeding fuel efficiently in a short period of time, is formed. The delivery schedule is notified to a controller of the construction machine. The delivery schedule is reconstructed by a set input of a change in the delivery schedule from the controller. A specified form for requesting expense of feeding fuel is automatically formed from a fuel feeding amount after fuel has been delivered and fed by the formed delivery schedule and confirming to feed fuel.
摘要:
A method of increasing the pressure-resistant strength and impact strength of a glass container, which comprises treating the surface of the glass container with a silane coupling agent, applying a coating material comprising a reactive compound having at least two (meth)acryloyl groups in the molecule to the treated glass container, and subjecting it to irradiation of an activated energy ray to cure the coating material applied; and a method of increasing the pressure-resistant strength and impact strength of a glass container, which comprises applying a coating material comprising a silane coupling agent and a reactive compound having at least two (meth)acryloyl groups in the molecule to the surface of the glass article, and then subjecting the coated glass container to irradiation of an activated energy ray to cure the coating.
