Title: Drive circuit for power mos transistor
Inventor: MAKINOSE KOUICHI
IPC: H03K17/567
Filed: 1994-03-02
Abstract: PURPOSE:To prevent the reduction in an output impedance of the drive circuit and to suppress a loss to drive the power MOS transistor(TR). CONSTITUTION:A complementary TR comprising TRs 2, 3 operated by a control signal for driving the power MOS TR is connected between high and low voltage power supplies. A gate of the power MOS TR 1 is connected to an emitter common connecting point of the complementary TR. Furthermore, constant current circuits C1, C2 activating the complementary TR at its active region based on a control signal are connected to a base common connecting point. Since the complementary TR is operated in the active region in this drive circuit, the reduction in the output impedance is prevented without using a resistor and a drive loss and heat generation by the resistor are prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce friction between the tip part of a center and a workpiece by forming a space for retaining lubricating oil in the peripheral surface of the tip of a shank coming into contact with the workpiece to smoothly supply the lubricating oil through the space in using the center. SOLUTION: To form a space for retaining lubricating oil in the peripheral surface of the tip of a shank, a plurality of belt-like chips are disposed to radially extend from the tip of the shank 2 toward the rear in the peripheral surface of the shank tip part 2. The chip space (g) is about 0.2 mm, the chip projection amount (h) is about 0.05 mm, and even during rotation of the workpiece, lubricating oil is retained in the space formed by the chip space (g). As the space is formed radially, lubricating oil is smoothly and surely supplied from the outside to the contact surface 4 between the center hole 6 of the workpiece 6 and the chip 3. Further, since four chips 3 are discontinuous, even if a crack is caused in one of chips, the crack is not propagated to the other chips.
