Abstract: To cut a protecting sheet adhered over the obverse of a wafer, an inclination angle of a cutting tool is adjusted according to a form of a chamfered part of the wafer and a finishing thickness of the wafer so that the protecting sheet is cut into the required minimum size for protecting the obverse of the wafer. Thus, the protecting sheet is not included inside a removed portion in a grinding process of the reverse of the wafer with a grindstone even if the wafer is ground to have extremely thin finishing thickness. Hence, the protecting sheet is not ground while the reverse of the wafer is ground, and the grindstone is thus prevented from being clogged up with ground material of the protecting sheet.
Abstract: To maintain high productivity and performing high-grade processes while minimizing deviation of a sheet process position in a direction at a right angle to a sheet conveying direction whatever types of sheets are to be processed, timing for starting detection of an end position of each of the sheets is controlled so as to execute the detection of the end position of each of the sheets at a vicinity of a sheet processing position on the sheet at which a sheet process is executed.
Abstract: A process and apparatus for fracturing, into a bearing cap and a connecting rod, an integral preform which defines a cylindrical aperture and two spaced-apart bolt seat shoulders. A guide member defines a first guideway along which moves a first slide member, the latter in turn defining a second guideway parallel to the first, along which a second slide member moves. A split mandrel has an upper part fixed with respect to the first slide member and a lower part fixed with respect to the guide member. The split mandrel halves define an internal tapered passageway for receiving a wedge capable of forcing the mandrel halves apart. Projections on the second slide member contact the bolt seat shoulders when the cylindrical aperture of the preform receives the split mandrel, and means are provided for urging the second slide member toward the mandrel.

Abstract: A water and dust-proof electric shaver head support structure that provides a wide range of movement to the floating shaver head to closely follow the contours of the skin. The floating shaver head, which contains the motor and shaving blades, freely pivots in the lateral plane and telescopically floats in relation to the shaver grip. A box-like space is formed in the shaver grip below the lower surface of the shaver head, and front and rear support walls extend upward from the shaver grip to support the shaver head in the forward/rearward direction.
Abstract: A hair clipper includes a handle portion having a drive end with a first coupler formation, and a blade assembly. The blade assembly includes a housing at least partially enclosing a reciprocating blade and a fixed blade, and having a top, bottom, and at least two sides joining the top and bottom. Integrally joined to and extending away from the bottom of the housing is a second coupler formation for engaging the first coupler formation. The first and second coupler formations form a releasable connection which inhibits movement of the blade assembly with respect to the handle portion when the two coupler formations are engaged.
Abstract: An apparatus and method for measuring the length of a cable for obtaining a reference measurement wherein a belt drive advances the cable through a first gripper until the cable is under separating/stripping cutters which cut the cable. The cable is advanced by a length measured by the belt drive, a leading cable-end being passed under a cable-end detector, and the cable is held tightly by the first gripper and with a linear backward movement, the cable is withdrawn until the leading cable-end leaves the cable-end detector. A correction factor is calculated by a control from the distance between the separating/stripping cutters and the cable-end detector and from the travel of the first gripper during the backward movement.
Abstract: A cutting tool having a cutting tip partially constructed from ultrahard materials. The cutting tip is oriented on the cutting tool such that the face has a reduced surface area. This has the effect of greatly reducing cutting tool costs and of maintaining the radius of the blade essentially constant even after repeated sharpening of the cutting tip.
Abstract: A method of cross-cutting a moving web uses a cutting knife operably mounted on a knife cylinder having a circumferential distance LZ where LZ is smaller than a cut length, LA.
