  • Patent number: 11520085
    Abstract: A transparent substrate having an antiglare function includes first and second faces. The transparent substrate has a resolution index value T, a reflected image diffusivity index value R, and a sparkle index value S satisfying T?0.25, R?0.8, and 0.75?S?0.95, respectively. The resolution index value T is calculated as (luminance of zero-degrees transmission light)/(luminance of total transmission light). The reflected image diffusivity index value R is calculated as (R2+R3)/(2×R1), where R1 denotes a luminance of reflected light reflected at first angle ?1, and R2, R3 denote luminance of reflected light at the second angle ?2, the third angle ?3, respectively, with respect to the first angle ?1. The sparkle index value S is calculated as 1?(Sa/Ss), where the first sparkle Sa and the second sparkle Ss denote a sparkle value of the transparent substrate and a sparkle value of a glass substrate, respectively.

  • Publication number: 20220250879
    Abstract: Provided is a work vehicle that can be transported by being loaded onto a trailer without having the outriggers removed. The work vehicle (rough terrain crane) is transported by being loaded onto a low bed trailer including a low bed and a high portion (first high bed, second high bed) higher than the low bed in at least one of the front and the rear of the low bed, and includes: outrigger units (front outrigger unit, rear outrigger unit) that are mounted to the front and rear of a vehicle body; and a lift unit that lifts and lowers the outrigger units (front outrigger unit, rear outrigger unit with respect to the vehicle body.

  • Publication number: 20190062206
    Abstract: A strengthened glass plate includes: a first functional layer that is provided in a first main surface of the strengthened glass plate; and a second functional layer that is provided in a second main surface of the strengthened glass plate. When a stress in a tensile stress layer is designated as CT, the following relation regarding the CT is satisfied: CT>0.8×[?38.7×ln(t/1000)+48.2], where t is a plate thickness [?m], CS is a compressive stress [MPa] in an outermost surface, and DOL is a depth [?m] from a glass surface to a point where the compressive stress reaches zero in a thickness direction.

  • Patent number: 9896375
    Abstract: A colored glass, a surface of which is roughened in whole or in part. In the colored glass, an average value of gloss values measured at 9 points in the surface thereof at an incident angle of 60° in accordance with JIS 28741 (1991) is 30 or less, a ratio of a difference between a maximum gloss value and a minimum gloss value to the maximum gloss value is 20% or less, and a minimum value of visible-light transmittance at a thickness of 0.8 mm is 70% or less.

  • Patent number: 8273262
    Abstract: The invention provides a method for etching which is intended for reducing the thickness of a glass substrate, and which attains a high etching rate and is capable of inhibiting haze generation on the glass substrate surface. The invention relates to a method for etching a glass substrate surface, comprising etching the glass substrate surface in an amount of 1-690 ?m in terms of etching amount, in which the etching is conducted with an etchant having an HF concentration of 1-5 wt % and an HCl concentration of 1 wt % or higher.
