Title: Manufacture of semiconductor device
Inventor: MIMURA AKIO
IPC: H01L21/762
Filed: 1982-08-23
Abstract: PURPOSE:To prevent the generation of a minute pyramid, and to obtain a practical recessed section by selective etching, etching the (110) face of an Si substrate in an anisotropic manner at rates Vd, Vc (<Vd) and sightly making Vd/Vc larger than cot beta/sintheta in an angle theta that a projected line to a bottom of an edge line formed by inclined planes of a face angles beta forms together with a crossed line with the bottom. CONSTITUTION:When a (110) face is etched in an anisotropic manner, an equivalent pyramid surface is formed in edge sections and the bottom of a groove 3. The pyramid satisfies l=t1 Vcsintheta, m=n.cotbeta, n=n.cotbeta, n=t1Vd after time t1, and the pyramid does not change or disappears because l>=m is formed. That is, (Vd/Vc)>=(cotbeta/sintheta) is formed. When a (313) face is selected as the inclined plane, Vc/Vd >=1.01 is formed from beta and theta, and a KOH-isopropyl alcohol group etching liquid in KOH concentration of 33-36wt% is practical for the formation of said formula. When using the (110) face, a KOH-H2O group is used, and a Br2-CH3OH group is used and a GaAs substrate is etched similarly on the GaAs substrate. According to the method, the generation of the ninute pyramid is prevented, even the errosion of the edge sections is inhibited up to a minimum limit, and the practical recessed section can be formed.

Title: Roll and its manufacture
Inventor: KUROKI TAKANORI
IPC: B23K9/04
Filed: 1978-11-28
Abstract: PURPOSE:To prevent the growth of initial cracks due to the thermal fatigue, and to manufacture the roll durable for long term service, by contriving the surface of the roll base so as to make the welding beads of an arbitrary type build-up weld layer to cross the welding beads of the second build-up weld layer just under the former layer. CONSTITUTION:The first build-up weld layer 2 of arbitrary type (wave, bend, spiral, etc.,) is applied to the surface of the roll base, and next, the second build- up weld layer 1 is applied onto the first layer 2, so as to make these beads to cross each other (can be at right angle); these passes are repeated for required times. As a result, even if cracks generate along the outermost beads 1, the cracks strike the welding beads 2 of the next layer; and the cracks hardly grow along the second beads 2, or the growth of cracks is rather arrested by the second beads, so that large cracks are not formed as a whole. Accordingly, the life of the roll can be greatly improved.

Abstract: PURPOSE:To control side pressure for a movable pulley by simple constitution by furnishing the shaft of the movable pulley with an oil flowout hole, which changes its degree of opening with movement of the movable pulley, and by leading one end of this oil flowout hole in communication to a side pressure chamber for movable pulley. CONSTITUTION:When the pressure of an oil pump rises, a slide spool 111 opens an oil flowout hole 110 against the action of a spring 114, when one end of the flowout hole remains shut by a movable pulley 79. The tension of belt 101 increases with acceleration of the car to cause increase of the side pressure to the belt, and accordingly the movable pulley moves to open said oil flowout hole 110. This will reduce the pressure in the side pressure chamber 83 to cause drop of the side pressure to belt. During deceleration of the car, the belt tension decreases, so that the oil flowout hole which has been open will be shut to maintain the side pressure high.
