Systems and methods for scribing and cleaving an optical fiber held by a ferrule are disclosed. The methods include operably supporting an optical fiber in a ferrule so that a bare fiber section of the optical fiber extends beyond a front end of the ferrule. The method also includes disposing a top-side location of a scribing medium to be in contact with a lower portion of the bare fiber section and a near-side location of the scribing medium to be in contact with the front end of the ferrule. The top-side location includes an abrasive feature while the near-side location is smooth. The scribing medium is moved relative to the bare fiber section to cause the abrasive feature to form a scribe mark at a scribe location at a distance from the front end of the ferrule. The smooth near-side location prevents substantial damage to the ferrule front end.

A method for manufacturing an acoustic wave device includes: forming an altered domain in a supporting substrate by irradiating the supporting substrate with a laser light, a piezoelectric substrate being joined to an upper surface of the supporting substrate; forming a groove on an upper surface of the piezoelectric substrate so as to overlap with the altered domain; and cutting the supporting substrate at the groove.

A manufacture method that includes positioning the permanent magnet body of which a surface is coated with a coating film for deterioration prevention, a scheduled cleavage portion of the permanent magnet body being located between two fulcrums, which are edge portions of a die, supporting the permanent magnet body, and cleaving the permanent magnet body into a cleaved magnet body and the magnet piece by pressing the scheduled cleavage portion of the permanent magnet body is provided. The manufacture method also includes cutting the coating-film between the cleaved magnet body and the magnet piece by pressing an end portion of the cleaved magnet piece from a pressing side of the scheduled cleavage portion, the end portion being on a side opposite to a cleavage surface side.

Disclosed herein are plaster boards that include first and second layers of hardened plaster material, a liner attached to the first layer of hardened plaster material, and a first material (e.g., a polymer material such as a viscoelastic polymer) adhered between the liner and the second layer of hardened plaster material. The liner includes one or more structurally weakened regions each extending substantially from a first edge to a second opposing edge of the plaster board. The structurally weakened regions of the liner may facilitate creation of a fissure that propagates substantially within a plane within the plaster board. Methods for making the plaster boards may involve drying wet plaster material while it is in contact with a liner having structurally weakened regions, processing a liner to form its structurally weakened regions while in contact with wet plaster material, or processing a liner to form its structurally weakened regions while in contact with hardened plaster material.

A process and an apparatus for making a refastenable side seam of an hygienic absorbent article efficiently, without the need to remove scrap and which allows refastenable side seams to be obtained which are ergonomic, aesthetically pleasing, easily identifiable by the user and such that they do not reduce the wearability of the article. The disclosure also relates to an hygienic absorbent article provided with at least one refastenable side seam. The disclosure also relates to a process and an apparatus for carrying out one or more operations on elastic panels usable for making an hygienic absorbent article provided with at least one refastenable side seam.

An optical fiber cutting device includes: a pair of grippers that grip an optical fiber having a glass portion exposed from the optical fiber; a gripping force applier disposed in one or both of the pair of grippers and that generates and changes a gripping force; a tension applier that applies tension to the optical fiber by separating the pair of grippers from each other in a longitudinal direction of the optical fiber; a tension measuring sensor that measures the tension; a controller that controls the gripping force; and a blade disposed between the pair of grippers in the longitudinal direction and that forms a scratch on the glass portion.

A printable blank sheet includes a sheet with defined separation lines, a first layer with cuts running through the first layer along the defined separation lines, and a second layer attached to a bottom side of the first layer, with perforations running through the second layer along the defined separation lines. A method for creating custom print cards includes running a printable blank sheet through a printer to print on defined print areas, wherein the sheet includes slit-over-perforation lines defining a periphery of an object in the sheet, bending the sheet along the slit-over-perforation lines to weaken and separate the slit-over-perforation lines, and detaching the object from the sheet.

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.

A device and method for cleaving a sample includes: creating an indentation on a top surface of the sample by applying a downward force along a vertical axis, the axis perpendicular to the top surface of the sample; providing a breaking pin located under the sample to touch the bottom surface of the sample at a position that is directly opposite from the indentation; and, a cleaving bar for applying a downward force on the sample by providing a left side and right side breaker pin wherein the downward force comprises a left-side downward force extended through the left-side breaker pin and right-side downward force through the right side breaker pin. Further, the pins that provide the left-side and right-side downward force are disposed on a breaker bar and arranged to be on opposite sides of a vertical axis that extends through the indentation on the top surface.

A method and tooling for fabricating a thin plastic plate of large format and of large thickness and including a card of small format and of small thickness that is detachable from the plate. The method, which may be implemented using the tooling, includes operations for making a spotface in a face of the plate to a depth equal to the difference between the large thickness and the small thickness; punching in the spotface zone along a leveling direction facing another face of the plate opposite from the first face, to a leveling stroke (e.sub.n) equal to the depth of the spotface, in order to bring the bottom of the spotface level with the first face of the plate; and pre-cutting an outline of the card within the leveled zone, in order to make the card detachable.
