Patent number: 11339087Abstract: 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.Type: GrantFiled: January 5, 2021Date of Patent: May 24, 2022Assignee: AGC INC.Inventors: Hitoshi Mishiro, Keiko Koyama, Minoru Tamada

Publication number: 20200039355Abstract: 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.Type: ApplicationFiled: December 16, 2016Publication date: February 6, 2020Applicants: Kabushiki Kaisha Toshiba, TOSHIBA INFRASTRUCTURE SYSTEMS & SOLUTIONS CORPORATIONInventors: Keiko KOYAMA, Tatsuro ABE
