Title: Manufacture of multilayer interconnection structure
Inventor: UCHIMURA SHUNICHIRO
IPC: H05K1/03
Filed: 1992-07-15
Abstract: PURPOSE:To realize a multilayer interconnection structure which is excellent in flattening the steps caused by wirings, by using as an interlayer insulating film a composition including a polyimide based resin precursor. CONSTITUTION:Aromatic tetrabasicacid dianhydride of 1mol and monovalent alcohol having at most four carbons/alcohol derivative of 0.1-1.0mol are heated in a solvent including a water content not more than 0.1wt.%, and a part of aromatic tetrabasicacid dianhydride is made into diester. Then, the foregoing material is made to react on an aromatic diamine compound, which has amino groups in the unsymmetrical places with respect to molecular major axis, and other diamine compounds of 0.8-1.2mol. Subsequently, the resultant composition including a polyimide based resin precursor is applied to a base material 1 having a wiring layer 2 wherein circuit patterns are formed, and an interlayer insulating film 5 is formed on the wiring layer 2 while curing the composition. Therefore, when an upper wiring layer 4 is formed on the interlayer insulating film 5 after forming through holes in the film 5, a highly reliable multilayer interconnection structure, wherein any step caused by making wiring layers into a multilayer interconnection is scarcely generated, can be realized.

Title: Electromagnetic relay
Inventor: YOKOO KIYOTAKA
IPC: H01H51/22
Filed: 1988-07-29
Abstract: PURPOSE:To reduce the amount of sliding movement of an armature on a permanent magnet so as to keep its property stable over a long period of time, by providing the supporting point of a hinge spring on the same flat face as the tangential plane on the tip of the armature, and also crank-shapedly forming it in combination with the hinge spring. CONSTITUTION:When a current is passed through its coil, an armature 20 is attracted to one end face of its iron core so that it is put in a sliding movement; were it not for engagement by a hinge spring 30, this movement will be such that its protrusion 21 rolls onto a permanent magnet 13 so that there will be no friction caused by the sliding movement and the armature will be placed across a dashed line; the angle formed by the sliding movement at this time is then indicated by theta1 and it is assumed that the supporting point A of the hinge pin 30 has been moved to a B point; but in fact the armature 20 is forced back by the spring force of the hinge spring 30 in its horizontal direction by HBA, which is the actual amount of its horizontal movement. Taking the form of a crank, the hinge 30 has some degree of freedom in its vertical direction in comparison with when it is T-shaped, so that the amount of forces by which the protrusion 21 is pressed to the face of the magnet 13 is reduced largely; its frictional force is decreased accordingly, and abrasion loss of the protrusion 21 can thus be reduced.
