Title: Manufacture of multilayer printed interconnection board
Inventor: UENO YUKIHIRO
IPC: H05K3/42
Filed: 1987-12-09
Abstract: PURPOSE:To reduce the manufacturing cost by a method wherein electroplating is applied to the end surfaces of interconnection layers in a through-hole to form conductor protrusions protruding toward the inside of the through-hole so as to be continuous with the respective interconnection layers and then through-hole plating is applied. CONSTITUTION:A multilayer interconnection board in which a through-hole 10 is formed is washed under a high pressure to eliminate cut trash and dust remaining in the hole 10. Then electrodes are lead out from interconnection conductors 4 and 5 of the inner layers and electroplating is applied. Conductor protrusions 8 and 9 are formed on the end surfaces of the interconnection conductor layers 4 and 5 on the wall surface of the through-hole 10. The protrusions 8 and 9 have circular shapes protruding along the wall surface of the through-hole 10. Thus, by forming the conductor protrusions on the end surfaces of the inner interconnection layers by electroplating after the through-hole is drilled, contact areas between the inner interconnection layers and a conductor layer formed by nonelectrolytic/electrolytic plating in a through-hole plating process afterwards can be increased so that the mechanical strength and the electrical connection at the connection parts of the through-hole plating layer and the inner interconnection conductor layers can be improved.

Title: Moving method for bloch line
Inventor: IIJIMA TETSUO
IPC: G11B5/02
Filed: 1987-12-11
Abstract: PURPOSE:To move a magnetic domain or a Bloch line generated in the magnetic domain and to drive with a low consuming power by using a gyloscopic force for receiving a magnetization change generated in a magnetic member according to a reverse magneto-striction effect in the direction of the vector product with the direction of a spin in a magnetic domain wall. CONSTITUTION:In a vertical magnetizing film consisting of ortho ferrite, mag netic garnet, amorphous magnetic material etc., an elastic wave generator 7 is provided by contacting the magnetic member including the magnetic domain wall 5 having the Bloch line 21 for separating the magnetic domain 3 from the magnetic domain wall 4. The elastic wave generated from this device 7 is guided to the magnetic member to generate a distortion synchronizing with the elastic wave in the magnetic member. The magnetization change is generat ed in the magnetic member according to the reverse magneto-striction effect to move the Bloch line 21 generated in the magnetic domain or the magnetic domains 3, 4 by the use of the gyloscopic force for receiving this magnetization change in the direction of the vector product of the direction of the spin in the magnetic domain wall. Thereby, the power for generating the elastic wave is reduced.

Title: Route search method with time limit
Inventor: MIZOGUCHI FUMIO
IPC: G09B29/10
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To obtain a route search method by which an optimum route or a route close to it can be searched within a time limit by changing the value of a weighting factor on the basis of a result obtained by judging whether a route search is finished or not within a given time limit during the route search. SOLUTION: A route search unit 4 starts a route search according to an algorithm based on the route search method with a time limit while the present position of a vehicle is used as a starting place. An obtained route is displayed on a monitor 5. That is to say, when the vehicle reaches a second point via a node (n) from a first point, an evaluation value in the node (n) is expressed by using a cost up to the node (n) from the first point, by using a minimum cost estimated to be required when the vehicle reaches the second point from the node (n) and by using a weighting factor. Whether the route search is finished within a given time limit or not is judged during the route search by using a present weighting factor. On the basis of its judged result, the value of the weighting factor is changed.  In this manner, a trade-off between the quality of a solution and the search time is adjusted well.
