Abstract: PROBLEM TO BE SOLVED: To inhibit a raising of a production cost of a blade and reduce an abrasion of a top surface and to prevent a generation of a flaw of a subject to be processed by making a longitudinal direction center portion of a blade top surface a straight line state parallel to a moving direction to be processed and making both ends a taper shape or a curved shape from a center portion to both ends. SOLUTION: In a blade 10, a top surface 2 is formed at a tip end of a body 1 and in a shape viewed in a longitudinal direction of a top surface 2, a longitudinal direction center portion is made a straight line state parallel to a moving direction of a subject to be processed and both end portions are made a taper shape descending from a center portion to both ends. The body is made of a steel. A top surface 2 is formed by joining ten diamond sintered chips 3 and three ultra hard alloy blocks 4 at both end portions on an upper surface of the body inclined to a thickness direction of the body 1. Thereby, an impact of a collision is relaxed when an end surface of a subject to be processed enters/retreats to a blade top surface, and an abrasion of a blade top surface is reduced.  A bad influence to a subject to be processed is disappeared by reducing an abrasion of a blade top surface and a generation of a flaw is prevented and a high accurate grinding processing can be carried out.

Abstract: PURPOSE:To improve the transmission efficiency, and also to reduce the power consumption by monitoring a utilization state of a terminal equipment by a monitor part in a main device, decreasing the polling frequency to the terminal equipment whose utilization factor is low, and also cutting a power source of the terminal equipment, in case a time value of until its restart exceeds a prescribed value. CONSTITUTION:A main device 1 always executes a communication to a terminal equipment 6 by a polling by a polling circuit 3. Also, a communicating state to each terminal equipment 6 is monitored by a monitor part 2, and a command 4 for decreasing the frequency of the polling to the terminal equipment 6 whose utilization factor becomes low low is outputted to the polling circuit 3. To a timer circuit 7 in the terminal equipment 6, a time value of until the restart in the course of the polling is set in advance at every device, and the timer circuit 7 executes this time counting. A stop command from the timer is executed by the polling from the main device 1, which is sent to its terminal equipment 6, and when the timer circuit 7 detects time-out, a power source cut-off command 8 is sent out to a power source controlling circuit 9, and a power source of its terminal equipment 6 is cut off. In this way, since the stop command from the timer is executed by the polling from the main device 1, the power source of the terminal equipment 6 whose utilization factor is low is cut off automatically by counting of the timer.
