Title: Production of microcapsule
Inventor: TSUDA MASAYUKI
IPC: G03F7/004
Filed: 1992-09-25
Abstract: PURPOSE:To uniformly form an aminoaldehyde resin around a water-insoluble core material without flocculating by using partially saponificated polyvinyl alcohol(PVA) having the degree of saponification within a specific range as a dispersant and polymerizing a precursor material around the water-insoluble core material, thereby forming the microcapsule. CONSTITUTION:The partially saponificated PVA having the degree of saponification within the 70 to 95% range is used as the dispersant at the time of preparing the microcapsule by polymerizing the precursor material of the aminoaldehyde resin around the water-insoluble core material in the presence of the dispersant, such as water-soluble high polymer. For example, an O/W emulsion is formed by emulsifying a liquid component to be used as the inclusion in the capsule in a water phase by using the dispersant. The wall film is thereafter formed if the initial condensate of a melamine-formaldehyde resin is added to this emulsion and making the emulsion to react by adjusting its pH to 4 to 6.5 and temp. to 60 to 100 deg.C. The pH is adjusted to 8 after cooling and the emulsion is washed by filtration, by which the photosensitive microcapsule is obtd.

Title: Design support device of integrated circuit
Inventor: OGUCHI MASASHI
IPC: G06F17/50
Filed: 1989-10-02
Abstract: PURPOSE:To design a resistance element pattern having a desired resistance value by installing the following: a coupling-region pattern storage means; a resistance-value computation means; and a length computation means. CONSTITUTION:A coupling-region pattern storage means 31 stores a shape and a resistance value of a coupling-region pattern 49. A resistance-value computation means 33 computes a resistance value of an intermediate-region pattern 53 based on information on an input resistance value and information on a resistance value stored in the means 31. A length computation means 35 computes a length 55 of a patterns 53 based on information on a resistance value of the pattern 53 computed by using the means 33. In this case, a distance between an end edge 52 coming into contact with an end edge coming into contact with the pattern 53 out of end edges of patterns 49 and a connecting part 39 becomes long because an end-part pattern 51 exists. Thereby, when a resistance element pattern 37 is cut vertically along the end edge 52, a degree of disagreement between a cut face and an equipotential face is small. Consequently, a resistance element pattern having a desired resistance value can be designed.
