Abstract: A clamping tool having a clamping head, a cylinder member coupled to an edge portion of the clamping head, a ram member coupled to and movably arranged within the cylinder member, a first die member coupled to the clamping head, and a second die member arranged to face the first die member and movable by the ram member toward and away from the first die member, wherein at least the clamping head is formed of a composite material prepared by dispersing at least one reinforcing material selected from the group consisting of ceramic fibers, ceramic whiskers and ceramic particles into a matrix metal consisting essentially of an aluminum alloy or a magnesium alloy. The clamping head is light, has a high Young's modulus, exhibits a high fatigue resistance, and is free from cracking and scattering of the cracked pieces. The clamping tool permits an operator to operate the clamping tool under a safe environment, and lessens the burden given to the operator, leading to an improved working efficiency.

Abstract: A razor having a base member, spring fingers extending from the base member, a plurality of razor blades, each of the razor blades having a generally tubular wall defining a central aperture, each of the razor blades having an integrally formed flange on a first end of the tubular wall, a free edge of each of the flanges comprising an annular cutting edge, a second end of the tubular wall having therein a plurality of the spring fingers extending into the aperture, such that the spring fingers within the tubular walls permit multi-directional movement of the razor blades responsive to pressures encountered during shaving operations.

Abstract: There is disclosed herein an apparatus for use in thermally binding documents. The apparatus includes a housing which defines a document receiving aperture. Biased supports are associated with the housing and in alignment with the aperture for compressing documents along an edge to be bound and for defining a predetermined binding position. A heater is associated with the housing and is positioned adjacent the predetermined position and support for heating the edge of the documents to be bound.
