摘要： A glass plate bend-breaking machine for a glass plate includes a supporting mechanism by which a glass plate with a predetermined bend-breaking line as a cut line formed on an upper surface, i.e., one surface, thereof is supported at a lower surface, i.e., another surface, of the glass plate; and press-breaking devices and for press-breaking the glass plate along the predetermined bend-breaking line. Each of the press-breaking devices has a pressing body for simultaneously pressing a plurality of parts and along the predetermined bend-breaking line on the upper surface of the glass plate at the time of press-breaking the glass plate along the predetermined bend-breaking line at each of press-breaking positions on the glass plate.

摘要： Provided is: a method of manufacturing plate-like members and an intermediate body for plate-like members whereby the occurrence of shape defects in the plate-like members can be prevented; and a plate-like member in which shape defects are prevented. The method includes the steps of: providing a first breaking groove 12a in a first principal surface of a base material for plate-like members, the base material having the first principal surface and a second principal surface opposed to each other, and then providing a second breaking groove 13a in the second principal surface of the base material in a direction crossing the first breaking groove 12a in plan view to form an intermediate body 11 for wavelength conversion members (plate-like members); and breaking the intermediate body 11 for wavelength conversion members into separate parts along one of the first breaking groove 12a and the second breaking groove 13a and then breaking the intermediate body 11 for wavelength conversion members into separate parts along the other breaking groove, wherein in breaking the intermediate body 11 for wavelength conversion members into separate parts along the first breaking groove 12a, the intermediate body 11 is broken into separate parts along the first breaking groove 12a by pressing the intermediate body 11 from the second principal surface 11b side, and in breaking the intermediate body 11 for wavelength conversion members into separate parts along the second breaking groove 13a, the intermediate body 11 is broken into separate parts along the second breaking groove 13a by pressing the intermediate body 11 from the first principal surface 11a side.

摘要： A method of manufacturing a glass sheet includes a start point forming step of forming a scribe line on a preset cutting portion of a glass sheet, a setting step of causing, through use of a support member having a groove-shaped recess, the support member to support the glass sheet having the scribe line formed thereon from one surface side so that the preset cutting portion is arranged on the recess, and a cutting step of generating a negative pressure in the recess to bend the preset cutting portion on the recess so that the one surface side protrudes, to thereby cut the glass sheet along the preset cutting portion with the scribe line as the start point. At the time of performing the cutting step, the entire recess is covered with a cover member from another surface side of the glass sheet through intermediation of the glass sheet.

摘要： Systems and methods are described for controlled crack propagation in a material using ultrasonic waves. A first stress in applied to the material such that the first stress is below a critical point of the material and is insufficient to initiate cracking of the material. A controlled ultrasound wave is then applied to the material causing the total stress applied at a crack tip in the material to exceed the critical point. In some implementations, the controlled cracking is used for wafering of a material.

摘要： A method of separating a transparent mother sheet includes contacting a first surface of the transparent mother sheet with an open ended pressure assembly including a pressure vessel shell, thereby forming a shell cavity defined by the first surface of the transparent mother sheet and the pressure vessel shell, where the transparent mother sheet comprises a damage path. The method also includes removing gas from the shell cavity through a fluid removal outlet extending through the pressure vessel shell to reduce a cavity pressure in the shell cavity, thereby applying stress to the damage path to separate a portion of the transparent mother sheet along the damage path.
