  • Patent number: 10106458
    Abstract: Provided is a method for producing a vehicle window glass, the method being adapted to prevent peeling-off of a functional thin film from a ceramic shielding layer without masking the ceramic shielding layer with a masking tape. This production method includes: an application step of feeding a coating liquid for forming the functional thin film onto a principal surface of a glass sheet on which the ceramic shielding layer has been formed beforehand, so as to allow the coating liquid to flow in a predetermined direction on the principal surface; and a drying step of drying the fed coating liquid. In the application step, the glass sheet is set in such a position that the predetermined direction coincides with a first direction in which the maximum length of the principal surface is 30 cm or less (rather than with a second direction in which the maximum length is more than 50 cm) and thus that the distance the coating liquid flows on the principal surface is limited to 30 cm or less.

  • Patent number: 9938371
    Abstract: A composition capable of forming a heat-dissipation member having high thermal conductivity, and a heat-dissipation member. The composition for the heat-dissipation member of the present application contains a polymerizable liquid crystal compound having, at both terminals, a structure including an oxiranyl group or an oxetanyl group; a curing agent that cures the polymerizable liquid crystal compound; and an inorganic filler formed of nitride. A curing temperature of the composition for the heat-dissipation member is within or higher than the temperature range in which the polymerizable liquid crystal compound exhibits a liquid crystal phase, and within or lower than the temperature range in which the polymerizable liquid crystal compound exhibits an isotropic phase. The heat-dissipation member formed of such a composition can have excellent thermal conductivity owing to a synergistic effect between alignment of the liquid crystal compound and the inorganic filler formed of nitride.
