Abstract: A cutting tool includes: a base metal provided with a seat portion; a blade edge member that is a polycrystalline diamond sintered material containing polycrystalline diamond and a binder; and a brazing material that fixes the blade edge member to the seat portion of the base metal. The blade edge member has a thickness of greater than or equal to 0.3 mm. The brazing material is disposed between a blade edge bottom face of the blade edge member and a seat bottom face of the seat portion and is in contact with the blade edge bottom face and the seat bottom face. The flank face is located outside of the base metal with respect to the lateral face of the base metal.

Abstract: A workflow system and method include tracking the physical movement of documents. The information of the physical movement is incorporated with the flow graph of a workflow. A display of the workflow can then be enhanced by the information relating to the physical movement of the document.

Abstract: Document monitoring provides a measure of document security. Documents incorporating radio frequency identification (RFID) tags can be monitored by appropriate interrogation components for movement activity. A surface suitable for placement of documents is configured for monitoring RFID tagged documents. Such documents can be monitored in a document processing device to control access to the document processing functions.

Abstract: An optical disc system includes an optical disc which is formatted to store data in sectors. A tracking error signal is monitored and if the tracking error signal exceeds a predetermined threshold level, the address information of a next sector following a target sector in which data is to be recorded or from which data is to be read out is read out. And, if the address information thus read out has been found to indicate an address which is consecutive to the address of the target sector, the occurrence of a tracking error is determined. On the other hand, if the address information thus read out has been found to indicate an address which is not consecutive to the address of the target sector, then the writing (recording) operation is terminated so as to prevent overwriting of data in an undesired sector.

Abstract: An optical disc is divided into a plurality of sectors each of which includes an address section, a flag section and a data section. First sector management data are stored in the flag section, normally in the form of a flag pit. In one aspect of the invention, the first sector management data are recorded in the flag section at higher laser beam power than the power used for recording data in the data section. In another aspect of the invention, second sector management data are additionally stored in the data section in the form of a special pattern. In this case, the second sector management data are read out if no sector management data have been read from the flag section of the sector.

Abstract: An optical type information recording medium has guide grooves for tracking formed in a concentric or spiral shape at a predetermined pitch; and a pre-format pit formed approximately midway between the guide grooves in the normal direction thereof and recording at least address information. The optical type information recording medium is constructed such that the predetermined pitch is a value ranged from 1.4 .mu.m to 2.0 .mu.m, and the depth of the pre-format pit is a value ranged from 0.46 .lambda./n to 0.58 .lambda./n where n shows the refractive index of a substrate of the medium and .lambda.
