Title: Manufacture of thin film multilayer wiring board
Inventor: SUZUKI TAKUMI
IPC: H05K3/46
Filed: 1989-04-07
Abstract: PURPOSE:To form accurately a fine thin film conductor pattern consisting of a plurality of layers by forming a flat organic insulating layer consisting of the 1st and 2nd coating films. CONSTITUTION:The formation of a coating film (polyimide film) is performed after dividing it two times so that a protruding part is buried on an irregular board 1. For the first time, polyimide liquid is applied in such an extent as to allow thickness obtained by heat-contraction to be almost equal to the difference in irregularities of the board 1 and after that, the coating film on the protruding part is removed. Then, subsequent contraction of the board under heat makes the upper surfaces of the polyimide film and the protruding part of the exposed board 1 uniform. Coating for the 2nd time is performed to make up a deficit of the thickness of the polyimide film. As originally coating film thickness is almost uniform, the whole surface contracts equally when heated and then the surface becomes flat. A fine thin film conductor pattern consisting of a plurality of layers is thus formed accurately.

Title: File transfer completion informing system
Inventor: IWATA MASAHARU
IPC: G06F13/00
Filed: 1988-04-12
Abstract: PURPOSE:To improve operability by recognizing the completion of file transfer between an independent host computer by an independent application program being unrelated to communication only by applying minor change on a communication program having a file transfer function. CONSTITUTION:The communication program 2 transfers a file to the host computer 6, and writes a message representing the completion of the transfer on an operating system 9 when the transfer of the file is completed. The message is read by the application program 3, and the application program 3 completes processing work. Thus, since the independent application program 3 being unrelated to the communication can recognize the completion of the file transfer between the host computer 6 only by applying the minor change on the communication program 2, it is possible to reduce the number of times of operation by an operator, and to improve the operability.

Abstract: PURPOSE:To fill up a gap between the inside of a negative pole consisting of crosslinking branched type polyacrylic acid and zinc and a separator, and check a rise in internal resistance during discharge as well as to aim at improvements in a closed circuit voltage characteristic, by adding straight chain type polyacrylic acid or its salt. CONSTITUTION:A positive pole black flux 1 with silver oxide as a main component is inserted into the inside of a positive pole vessel 2 together with a positive pole ring 3 and molded by means of compression. And, an alkaliproof separator 4 and an electrolyte impregnating material 5 are placed on a black flux. On the other hand, straight chain type polyacrylic sodium of below 2,500 in a degree of polymerization is dissolved in an aqueous solution of caustic potash and a viscous electrolyte is thus formed. In addition, colloidal zinc powder and crosslinking branched type polyacrylic sodium are mixed in a state of being powdered, filling a sealing plate 7 with it, and the viscous electrolyte is injected into this mixture. The sealing plate 7 provided with a colloidal negative pole 6 is combined with the positive vessel 2 via a gasket 8, tightening an opening edge of the vessel 2, and a hermetically sealed battery is made up in this way. A silver oxide battery secured like this is excellent in weighing accuracy of a negative pole active material and a discharge characteristic as well as in low temperature closed circuit voltage.
