  • Publication number: 20060229464
    Abstract: The present invention provides a stabilized (meth)acryloyloxyalkyl isocyanate, a process for stabilization thereof and a process for preparation of the same. More particularly, it provides a (meth)acryloyloxyalkyl isocyanate having a small hydrolyzable chlorine content and good storage stability, a process for stabilizing a (meth)acryloyloxyalkyl isocyanate prepared using phosgene which process comprises decreasing the amount of a hydrolyzable chlorine with purification and a process for preparation of a stabilized (meth)acryloyloxyalkyl isocyanate. An acidic gas such as carbon dioxide or the like was forcedly dissolved in (meth)acryloyloxyalkyl isocyanate, particularly (meth)acryloyloxyalkyl isocyanate which content of hydrolyzable chlorine is decreased with purification and thereby the storage stability of the (meth)acryloyloxyalkyl isocyanate is improved.

  • Publication number: 20040020598
    Abstract: A processing apparatus for subject of the present invention uses a high voltage electrode and a ground electrode, and generates plasma under atmospheric pressure in a reaction passage through which a to-be-processed subject passes. For example, even fluorocompound such as PFC including CF4 can effectively be decomposed because the fluorocompound is brought into contact with plasma in a small space for sufficient time, and the apparatus has a small and simple structure. Therefore, the apparatus can be added to each process chamber.

  • Publication number: 20020031250
    Abstract: There are provided a method and apparatus for examining through holes, in which determinations as to whether the examined through hole are good or bad can be accurately made at low costs. A light source and a sensor camera having a plurality of imaging elements are disposed with a table on which a work piece having through holes is mounted being interposed between the light source and the sensor camera. Light passing through the through holes is imaged by the sensor camera, wherein the sensor camera is set such that a focal point of the sensor camera is shifted from the surface of the work piece to thereby apparently expand an area of the image of the passing light.
