The present invention provides a dresser for a chemical and mechanical polishing cloth wherein a bonding material for retaining diamond grit is not dissolved and contamination of chemical slurry caused by dissolving of metal or peeling-off of diamond grit is prevented from occurring. A sintered product constituting the dressing face,is obtained by mixing a bonding material,consisting of silicon and/or silicon alloy with diamond grit,, and forming and sintering the mixture. A carbide film,generated by sintering silicon in the bonding material into diamond is formed on the surface of the diamond grit,. Thereby, the diamond grit is firmly bonded with the bonding material, and the bonding material is not dissolved. As a result, the contamination of the chemical slurry or the peeling-off of the diamond grit is prevented.

Dresser for polishing cloth and manufacturing method therefor

A powder of diamond or high-pressure phase boron nitride core particles charged into a coating space as it is dispersed, and a precursor of a coat forming substance allowed to contact and/or impinge against the particles in the powder of core particles so that their surfaces are covered with the coat forming substance, thereby preparing coated diamond or high-pressure phase boron nitride particles which are subsequently sintered. The thusly produced diamond of high-pressure phase boron nitride sinter is composed of coated core particles of high performance that are superhard, uniform, dense and sintered firmly, and which have a controlled microstructure.

Diamond sinter, high-pressure phase boron nitride sinter, and processes

The invention relates to a bar code label printer including a label sheet feeding unit for feeding a label sheet on which plural labels are adhered to at regular intervals, a printing unit for printing a bar code on the respective labels, a label peeling unit for peeling the printed labels from the label sheet, a sheet drawing unit for drawing the label sheet after the peeling unit, a bar code verifying unit for verifying the bar code printed on the label to detect an ineffective bar code, a re-printing unit for re-printing the same bar code as the ineffective bar code on the next label when the bar code verifying unit detects the ineffective bar code, and an ineffective bar code label remaining unit for remaining the ineffective bar code label on the label sheet without peeling. A bar code label issuing method uses the above described bar code label printer to issue only effective bar code label in an automatically control manner.
