Abstract: PURPOSE:To excavate the lower part of a supporting plate by protruding the cutter of an auxiliary excavating device from the edge of a cutter drum to the supporting plate in a section where a guide arm does not interfere with the supporting plate. CONSTITUTION:In a section where a guide roller 26 interferes with a supporting plate 2, a guide plate 26 is put in contact with the side face of the supporting plate 2 and guide arm 14 is oscillated in the direction of spacing apart from the supporting plate 2. This oscillating force is transmitted to a cutter supporting arm 16 and so a cutter 18 is saved to a position where it does not interfere with the supporting plate 2. On the other hand, when a cutter drum 4 is rotate and an auxiliary excavating device 10 is apart from the outside face of the supporting plate 2, the guide arm 14 is protruded to the lower inside of the supporting plate 2 and the cutter 18 is protruded near the position of a sectional center line on the lower side of the supporting plate 2 to excavate remaining portions.

Abstract: PURPOSE:To improve the attachment accuracy of a magnetic head and to avoid giving damage to a magnetic medium, by supporting upper and lower magnetic heads with a nonmagnetic thin plate spring having a gimbal structure applying a cutting. CONSTITUTION:Cuttings 30-33 are formed symmetrically on the basis of a straight line X-X' to nonmagnetic thin plate springs 23 and 28 attached to upper and lower magnetic heads 21 and 27. At the same time, U-shaped cuttings 34-37 which are symmetrical centering on the line X-X' are formed at the inside of cuttings 30-33. Thus a springy gimbal structure is obtained.

Abstract: PURPOSE:To obtain the high-performance thin-film magnetic head which has narrow track width, and excellent high frequency characteristics and a good S/N, and small Barkhausen noise by making the length of an upper magnetic layer in a track width direction larger than yoke length, and clamping a lower magnetic layer which has specific height in a substrate as a self-lubricating block. CONSTITUTION:The lower magnetic layer 2 is clamped in the nonmagnetic substrate 1 made of the self-lubricating block and a spiral coil 3 is laminated thereupon having both its terminals 3a projected. The width (d) of the lower magnetic layer 2 is made narrow suitably for the recording and reproduction of a recording medium having high track density and smaller than the height (c) of the magnetic layer 2. The upper magnetic layer 4 is formed on the coil 3 and its length (a) in the track width direction is made larger than the yoke length (b). Consequently, the internal magnetism of the magnetic layer 4 has an easy magnetization axis in the width direction because of shape anisotropy. Further, the easy magnetization axis of the lower magnetic layer 2 is in the height direction. Thus, the high-performance thin-film magnetic head which has excellent high frequency characteristics and the good S/N ratio and small Barkhausen noise is obtained.

Abstract: PURPOSE:To reduce the gate resistance and make lateral diffusion small by forming a structure equipped with an insulation film coating the side wall surface of the silicide layer of a high melting point metal constituting a gate electrode, and with a conductive semiconductor region disposed in an array with the insulation film on an active layer. CONSTITUTION:Si ions are implanted to the element-forming region at the surface layer part of a semi-insulation substrate 11 of compound semiconductor, and heat treatment for activation is carried out; thereby an N type active layer 12 is formed. Next, a triple layer of the silicide layer of high melting point metal such as a WSi layer 13, an intermediate layer such as a Tin layer 14, and a high conductive metallic layer 15 of Au or the like. Then, the layer 13 is selectively removed by the use of CF4 for reaction gas, and an SiO2 film 17 is formed over the entire surface.

In the state that the side wall part of the layer 13 is coated with an SiO2 film 16, N<+> type GaAs layers 16 are selectively grown. The end of this layer 16 does not contact with the layer 13, which causes no decrease in withstand voltages of the gate and source or drain.
