  • Patent number: 11339087
    Abstract: An antiglare glass substrate includes a glass substrate having a first main surface and a second main surface that is opposite to the first main surface. The first main surface has undergone an antiglare treatment and a fluorine-containing organosilicon compound coating film as an antifouling film is laminated thereon. The first main surface partly includes a non-antiglare-treated portion that has not undergone the antiglare treatment. The non-antiglare-treated portion has a surface roughness Ra of less than 10 nm. A difference in height along a plate thickness direction of the glass substrate between the antiglare-treated portion that has undergone the antiglare treatment and the non-antiglare-treated portion is 10 ?m or larger and 200 ?m or less.

  • Publication number: 20200079052
    Abstract: The present invention relates to a plate with a printing layer containing a plate having a first main surface, a second main surface and an edge face, and a printing layer provided on a periphery of the first main surface, in which the plate has an outer circumferential part corresponding to an outer circumferential part of the printing layer and an inner circumferential part corresponding to an inner circumferential part of the printing layer, in which the outer circumferential part of the plate has, in at least a part of the whole circumference, an outer circumferential region, and the inner circumferential part of the plate contains an inner circumferential region corresponding to the outer circumferential region, and in which the outer circumferential region has a surface roughness R2 and the inner circumferential region has a surface roughness R1, and R2>R1 is satisfied.

  • Publication number: 20200039355
    Abstract: A switching control device includes a controller, a prediction unit, and a calculator. The calculator calculates, based on a schedule, a first electricity storage amount of a first electricity storage functional unit required for driving a motor to a second position excepting a charging amount charged to the first electricity storage functional unit at a first position corresponding to a charging time based on the schedule. When an electricity storage amount of the first electricity storage functional unit is equal to or smaller than the first electricity storage amount, the controller controls a switching unit to switch a power source of an air conditioning appliance to a predetermined power source from the first electricity storage functional unit.
