摘要:
A bent glass sheet (1) with a light-shielding film for vehicles includes a glass sheet, and a light-shielding film formed in at least a part, i.e. a film-formed portion (11), of a peripheral portion of one surface of the glass sheet. The light-shielding film is composed of a band-shaped film (12) and a dot-patterned film (13). The band-shaped film is arranged in an outer part of the peripheral portion. The dot-patterned film composed of a plurality of dots (14) is arranged in an inner part with reference to the band-shaped film. The plurality of dots are positioned so that a distribution of the dot shielding ratios decreases from the edge of the band-shaped film toward a side of a glass surface (a non-film-formed portion (15)) on which the band-shaped film is not formed, where the dot shielding ratios are values of peaks of mountains formed of a distribution of the dot-width shielding ratios, or dot-diameter shielding ratios. A region in which the dot shielding ratio is at least 50% extends up to at least 4 mm from the edge of the band-shaped film.
摘要:
A bent glass sheet shaping method which is capable of reducing occurrence of visibility distortions and a bent glass sheet with reduced visibility distortions. A glass sheet is heated to a shapeable temperature, a cover material is mounted onto a press die such that a direction of waves in the cover material is diagonal to a direction of distortions in the glass sheet, and the heated glass sheet with the press die is pressed.

A ceramic paste is applied to a first glass sheet 11, and a ceramic paste is applied to a second glass sheet 13 with a lower solar absorptivity than that of the first glass sheet 11. In this case, the amount per unit area of the ceramic paste to be applied to the first glass sheet 11 is allowed to be smaller than that of the ceramic paste to be applied to the second glass sheet 13. Alternatively, a first ceramic paste and a second ceramic paste are allowed to have different compositions from each other. The first glass sheet 11 and the second glass sheet 13 are bent so that the surfaces onto which the ceramic pastes have been applied are shaped as concave surfaces. The applied ceramic paste is fired using the heating used for bending. Thus maskings 12 and 14 are formed. The first glass sheet 11 and the second glass sheet 13 are bonded to each other, with a resin interlayer film 15 being interposed therebetween.

摘要:
A tempered glass sheet having a sufficient strength needed for a windowpane and can be utilized for smoothing a surface of the window is provided. A tempered glass sheet of the present invention, produced by tempering a glass sheet, has a stepped portion of reduced thickness relative to the thickness of the glass sheet in at least a part of a peripheral portion of the tempered glass sheet. By the stepped portion, a thin portion and a thick portion are formed. A difference in thickness between the thin portion and the thick portion is 0.5 mm or more, and the thickness of the thin portion is thicker than half the thickness of the thick portion.

A bent glass sheet for a vehicle window of the present invention has a roughened region for eliminating distortion of transmitted light through the bent glass sheet. The bent glass sheet comprises a main surface surrounded by an edge of the bent glass sheet and the main surface has a smooth transparent region. The main surface also has the roughened region that covers at least a portion of a peripheral region of the main surface and in the portion of the peripheral area the roughened region extends at least 3 mm from the edge of the bent glass sheet. The roughened region covers an area in which the transmitted light are distorted. Therefore, the discomfort of passengers due to distortion of transmitted light is relieved.

A vehicle glass (10) comprises an outer glass plate (31) adjacent to the exterior of the vehicle, an inner glass plate (32) adjacent to the interior of the vehicle, and an intermediate film (33) that joins these glass plates. The outer glass plate is a bent glass plate formed by printing a black ceramic layer (14) on a face of a glass plate (13) adjacent to the interior of the vehicle, covering the black ceramic layer with a printed silver layer (12), and bending using a press-bending device. When a reflection color tone is obtained by measuring a portion at which the printed silver layer is printed from a side of the layer on which the glass palate lies, the chromatic coordinate b* in the CIE 1976 color system defined in JIS Z 8729 does not exceed six.

摘要:
In a vacuum processing apparatus including a plurality of vacuum transfer vessels arranged back and forth at the back of a lock chamber, an intermediate chamber arranged between them and capable of accommodating wafers, and processing units connected to respective vacuum transfer vessels, a wafer processed in a pre-processing vessel out of the processing units connected to the respective vacuum transfer vessels is transferred to a post-processing vessel connected to the same vacuum transfer vessel and post-processing is performed.
摘要:
A curved laminated glass having no natural vibration in the low frequency region of 500 Hz or lower is fitted to a vehicle body, so that the curved laminated glass is prevented from resonating with the vehicle body. A resin interlayer film that bonds two curved glass sheets to each other to allow a curved laminated glass to be obtained is, for instance, a film with a three-layer structure (sound insulation film) including polyvinyl butyral films and a polyvinyl n-octylal film interposed therebetween. The resin interlayer film to be used is a soft film having a Shore hardness of 75 degrees or less at 20° C.
