PROBLEM TO BE SOLVED: To provide a method of loading and cutting a glass sheet by which idle time is decreased and to provide a cutting table. SOLUTION: In the method of loading and cutting the glass sheet on a cutting table, ruled line is provided on the sheet 4 by a ruling head 5. In the ruling process, a pickup arm 11 with a sucking device is drawn from the lower side of the sheet 4 to be worked and inclined to mount the sucking device 12 on the vertically arranged sheet 4 to be picked up to pick up the sheet 4. The picked up sheet 4 is started to be inclined toward the cutting table 1 on which the sheet 4 exists and after the ruled sheet 4 is moved from the table 1, the ruling head 5 is positioned beyond a sheet supporting zone to be in the opposite side to a pickup zone and the sheet 4 is mounted on the cutting table 1.

PROBLEM TO BE SOLVED: To provide a laser beam machining method and device by which an alteration layer can be formed at a desired position in a plate even in the presence of variance in the thickness of the plate. SOLUTION: The laser beam machining method is such method that a plate formed with a lattice like intended dividing lines (lines) on the surface is held on a chuck table, and that the plate so held on the chuck table is irradiated with a transmissible laser beam along these lines to form an alteration layer along the lines inside the plate. The method includes a process for detecting a height position of the surface to be irradiated with the laser beam along the lines of the plate held on the chuck table, and a process for emitting the laser beam along the lines while the focal position of the laser beam is controlled corresponding to the height position detected by the detecting process.

Abstract:
A slider is attached to a cutter main body of an optical fiber cutter in a forward/backward movable state. A round blade member for making a scratch in an optical fiber is attached to the slider in a rotatable state. An operation lever pin for changing over rotation operation modes from one to another is attached to one end side of a pin member which penetrates a wall of the cutter main body. The rotation operation modes include a non-rotation mode for preventing the round blade member from being rotated and a continuous rotation mode for rotating the round blade member by a predetermined angle with every backward movement of the slider.

PROBLEM TO BE SOLVED: To provide an optical fiber cutting device capable of applying a tensile stress and a flexural stress to a glass core wire evenly on right and left sides when cutting an optical fiber by pressing a top face of the glass core wire corresponding to a start point scratch with a pad.SOLUTION: An optical fiber cutting device comprises: a fiber holding part that holds a coating part of an optical fiber to be cut; a fiber holding part that is arranged apart from the fiber holding part with a predetermined interval and holds a glass core wire part of the optical fiber with the coating removed; a round blade unit including a round blade that puts a start point scratch on a bottom face of the optical fiber glass core wire held by the fiber holding parts; and a pad that presses a top face of the glass core wire corresponding to the start point scratch from above, applying a tensile stress and a flexural stress to the glass core wire. In the pad, at least an end surface that presses the glass core wire is made of a hard material, is formed in R-shape along a shaft direction of the glass core wire, and is processed to have a smooth surface.

PROBLEM TO BE SOLVED: To provide a wafer dicing press apparatus which can improve productivity.SOLUTION: A wafer dicing press apparatus 100 comprises a support member 10 supporting a first surface of a wafer W and a pressure device 20 applying pressure to a second surface of the wafer W. The pressure device 20 includes a pressure dispersion device 22 applying pressure generated by a pressure generation device 21 to the second surface of the wafer W. The pressure dispersion device 22 transmits the pressure generated by the pressure generation device 21 to the wafer W by a diaphragm 221. At this time, the diaphragm 221 is firmly attached to the wafer W with being deformed to the wafer W side by pressure of a working fluid 1 in a frame 211 to apply the pressure of the working fluid 1 to the wafer W in an uniformly dispersed manner. Accordingly, cracks grow inside the wafer W starting from a laser damaged layer formed inside the wafer W, which serves as a division starting point, and thereby a number of semiconductor elements formed on the wafer W are divided into individual pieces.
