A segment type diamond tool, used for cutting or drilling brittle substances, such as stones, bricks, concrete structures, or asphalt structures, is disclosed. In the diamond tool, the segments are each set with diamonds in a single-layered structure or a multi-layered structure, and are alternately or intermittently arranged on a steel core, different from conventional diamond tools having segments randomly set with diamonds. Such a diamond arrangement of this invention allows the diamonds to more effectively perform their cutting action, and so the diamond tool has an increased cutting rate, in addition to reducing the amount of fine debris generated during a cutting or drilling process to ill-affect workers health or cause environmental pollution. In the segments each set with diamonds in the single-layered or multi-layered structure, the diamond arrangement is designed such that the diamonds of each trailing segment form grooves on the surface of a brittle substance along the lands between grooves previously formed on the surface of the brittle substance by the diamonds of a leading segment.

A diamond blade having rim type cutting tip for use in apparatus such as cutting saw machine having a structure which rim type cutting tip is able to produce cutting chips with relative large size during cutting operation so that those chips are easily discharged outside with reducing the friction with cutting tip of blade, thereby to increase cutting ability and to prevent the chips dispersing in the air and giving rise to the bad effects to user's health and the contamination of environment. The diamond blade according to the present invention comprises a wheel body connected with a shaft of electric motor, and rim type cutting tip for cutting or grinding crushable materials disposed on the circumference of the wheel body and composed of at least two diamond layers longitudinally disposed parallel with the rotation direction of the blade in which diamond particles are included, and non-diamond portion disposed between the diamond layers in which diamond particles are not included.

In a method and system for controllable electrostatic-directed deposition of nanoparticles from the gas phase on a substrate patterned to have p-n junction(s), a bias electrical field is reversely applied to the p-n junction, so that uni-polarly charged nanoparticles are laterally confined on the substrate by a balance of electrostatic, van der Waals and image forces and are deposited on a respective p-doped or n-doped regions of the p-n junction when the applied electric field reaches a predetermined strength. The novel controllable deposition of nanoparticles employs commonly used substrate architectures for the patterning of an electric field attracting or repelling nanoparticles to the substrates and offers the opportunity to create a variety of sophisticated electric field patterns which may be used to direct particles with greater precision.

An improved toothbrush comprising a thin bristled pick rotatably mounted at the bottom end of the toothbrush handle. A rotating device allows the bristle pick to be extended roughly 85 degrees from the handle shaft so that the user may insert the pick between the teeth with ease for cleaning purposes. When not in use, the pick may be stored within the shaft of the toothbrush by rotating it inward and into a small rectangular cavity in the shaft. The added bristled pick feature allows users to attain enhanced tooth cleaning benefits from one device instead of a plurality of cleaning utensils.
