Abstract: PURPOSE:To enable the reduction of coverage failure due to steps by method wherein an impurity region formed on a semiconductor substrate is made to serve as a gate electrode, and a source and a drain are formed on a semiconductor monocrystal layer laminated on the semiconductor substrate through the intermediary of an insulating layer which is to serve as a gate insulating film. CONSTITUTION:An electrode 12 is formed on a specified region of the surface of a semiconductor substrate 11, a gate insulating film 13 is formed on the surface of the substrate 11, and a monocrystal semiconductor layer 14 is formed on the gate insulating film 13. A source region and a drain region 15 are formed on a specified region of the monocrystal semiconductor layer 14 by selectively introducing an n-type impurity, and a channel region 16 formed of a part of the monocrystalline semiconductor layer 14 where the n-type impurity has not been introduced is present between the source region and the drain region 15. An interlaminar insulating layer 17 and a flattening insulating layer 18 for flattening are formed on the monocrystalline semiconductor layer 14, and a source and a drain electrode, 19 and 19, both connected to the source and the drain 15 respectively through contact holes formed so deep as to reach to the source and the drain 15 respectively are formed on the interlaminar insulating layer 17 and the flattening insulating layer 18. In this case, steps are prevented from occurring and the contact holes are made large in dimension, so that coverage failure hardly occurs in the source and the drain electrode.

Title: Production of hollow yarn bundle
Inventor: NAKAMARU HIROYUKI
IPC: B01D69/08
Filed: 1988-01-25
Abstract: PURPOSE:To eliminate an intermediate stage which has been conventionally performed by using a bobbin, and to improve the productivity and quality of hollow yarn bundles by forming an endlessly enclosing hollow yarn bundle by winding the hollow yarn drawn in a spinning apparatus directly around a hank, and cutting the hollow yarn bundle at specified positions. CONSTITUTION:An endlessly surrounding hollow yarn bundle 14 is formed by winding hollow yarn 13 drawn in a spinning apparatus 11 directly around a hank 12. A terminated linear hollow yarn bundle 15 is obtd. by cutting the above described hollow yarn bundle 14 at specified positions in its winding direction, for example, at positions corresponding to intersection point of each edge of the hank 12. Thus, a labor for handling pallets for housing bobbins or for attaching and detaching the bobbins to a spinning apparatus or to a reeling machine, etc., are eliminated, saving the time required for supplementing the bobbins for winding or feeding the hollow yarn to a spinning apparatus. Moreover, the quality of the hollow yarn bundle is improved because bending of the hollow yarn due to winding of the yarn around a bobbin is not generated.

Title: Electromagnet device
Inventor: MATSUO KENICHI
IPC: H01F7/14
Filed: 1986-01-23
Abstract: PURPOSE:To easily obtain the desired attracting force by matching the end surface of the inserting part of yoke piece within the through-hole of bobbin and making the side surface of inserting part into contact with pressure with the side surface of extra yoke. CONSTITUTION:An extra yoke 4 is formed by a bar type material having the square section, it is then inserted into a through-hole 2a of a bobbin 2 and both end portions are projected from the through-hole 2a. In the yoke 5, the internal surfaces of inserting portions 6a, 7a of the L-shaped yoke pieces 6, 7 are placed in contact with pressure with the side surface of the extra yoke 4, and the inserting portions 6a, 7a are cut away at the upper and lower end portions and narrowed. Moreover, since the extra yoke 4 of almost the same width is also provided along the yoke 5, the height does not increase even when a coil 3 is wound to the inserting portions 6a, 7a through the bobbin 2 and thereby an electromagnet device 1 can be formed thin. The desired attracting force can be attained without increase of magnetic resistance by compensating for the sectional area of the inserting portions 6a, 7a which are reduced by cutting away the extra yoke 4. If the extra yoke is formed by the material having higher permeability than that the material of yoke piece, the inserting portions of yoke piece can be more narrowed and a thinner electromagnet can be formed.
