Filed: 1991-09-05
Abstract: PURPOSE:To enhance the sharpness of the whole cutting edge, and to prevent the occurrence of breakage or the like of the cutting edge by setting great the rake angles in the axial and radial directions of the main cutting edge on the base end side of a tool. CONSTITUTION:The rake face 28 to be formed on the circumferential surface of a tip body 21 so as to continue to both of a main cutting edge 24 and an auxiliary cutting edge 27 is formed in a multistep surface projectedly and curvedly bent along the circumferential direction of the tip body 21 by a plurality of constituting surfaces 28A to 28C. When the tip is fitted to the cutting tool such as a face milling cutter or the like in such a state that the rake face 28 is set to face the front side in the turning direction of the tool, the rake angle in the axial direction of the rake face 28 is steppedly increased toward the positive angle side from the constituting surface on the foremost end side of the cutting tool body to the constituting surface positioned on the base end side. These surfaces are so formed that as go away from the nose part 29 where the main cutting edge intersects the auxiliary cutting edge, the intersection angle between the constituting surface and the end surface 22 continued to the main cutting edge 24 is steppedly decreased.

Abstract: PROBLEM TO BE SOLVED: To provide a power supply for electric discharge machining which can generated electric discharge machining current pulses having a steep rising and falling velocity and so excellent machining efficiency. SOLUTION: When a dischargeable condition is generated, switching elements T2 and T3 are turned on, and from an auxiliary DC power supply 2 of low voltage an electric discharge machining current I0 is sent to between a workpiece W and an electrode P.

When the switching element T1 is turned off, the machining current I0 shows the peak value, which is held by the current fed from the auxiliary DC power supply 2.  When the set pulse width has elapsed and the switching elements T2 and T3 are turned off, the current due to the induction energy is fed back to the main DC power supply 1 through diodes D1 and D2, and the machining current falls steeply, when a rectangular machining current waveform will be obtained which ensures effective machining.

CONSTITUTION:Because the impurity concentration of an epitaxial P<+> type layer 14 is easy to control, the thicknesses of the depletion layers 10 and 11 between the P<+> type layer 14 and N<+> type layers 6 and 7, which constitute a memory cell and bit lines, are controlled in a wide range and the number of electron-positive hole pairs induced in those layers by alpha-rays is reduced to the level of soft-errors. As a starting material, a P<+> type epitaxial wafer is employed so as to eliminate implantation/diffusion processes of the impurity. The impurity concentration of about 10<15>cm<-3> of a P<-> type layer 1, the impurity concentration of about 10<16>-10<18>cm<-3> of the epitaxial P<+> type layer 14 and the impurity concentration of about 10<18>-10<20>cm<-3> of the N<+> type layers 6 and 7 have improvement effect against soft-errors and, at the same time, provide sufficient allowance for junction dielectric strength. With this constitution, manufacturing process can be simplified and rate of soft-errors caused by alpha-rays can be improved.
