A method for producing a bent glass article includes a heat treatment step of heat-treating a bent glass. The bent glass includes a first main stir-face, a second main surface and an end face. In the heat treatment step, the bent glass is supported by a support jig with one of the main surfaces facing downward. The support jig supports at least a part of one of the main surfaces or the end face in a higher position than the lowest position of one of the main surfaces.

Gyroscopes are sensors that measure angular rate and angular orientation. A three-dimensional fused silica micro shell rate-integrating gyroscope is presented. One aspect of the gyroscope includes the use of optical sensors to detect motion of the resonator. The proposed gyroscope is attractive because it achieves several magnitudes higher accuracy as well as high vibration and shock insensitivity from a novel resonator design as well as other unique manufacturing processes.

A laminated includes two bent glass substrates, a polymer interlayer between the glass substrates, and a notch or orifice cut in an entire thickness of the glazing. The glazing includes a border of compressive edge stresses obtained by general controlled cooling of the substrates in a paired state so that compressive stresses are generated at the border, and a local compression zone, different from the border, and obtained by local controlled cooling of a local area of a main surface of the glazing so that compressive stresses are generated in theid local compression zone. The notch or orifice is located in the local compression zone and made in the substrates in a paired state after forming the local compression zone so that cut contours of the substrates in the notch or orifice have a perfect superposition. The compressive edge stresses of the cut contours are greater than 4 MPa.

A device for forming a glass includes a housing member, a support member, and an intake member. The housing member includes a first part, at least one suction hole, and a plurality of sidewalls. The first part is substantially parallel to a surface defined by first and second directions. The suction hole is defined in the first part. The sidewalls extend from the first part. The support member is disposed on the first part. The support member includes a first surface configured to support the glass, a second surface overlapping and facing the first surface in a thickness direction, and a plurality of side surfaces configured to connect the first surface to the second surface. Each of first and second side surfaces of the side surfaces face each other and have a curved shape. The intake member is configured to perform an intake operation through the suction hole.

A process and system for forming a curved glass article from a sheet of glass material is provided. The process and system includes supporting a glass sheet on a shaping frame and then heating the sheet of glass material while supported by the shaping frame such that the central region of the sheet of glass material deforms into an open central cavity of the bending frame. The process and/or system are configured such that an aspect of the heating experienced by an outer region of the sheet of glass material is less than an aspect of the heating experienced by the central region of the sheet of glass material. The aspect of heating may be the average temperature, the maximum temperature and/or the heating rate, which Applicant believes may reduce certain defects during the shaping operation.
