Abstract: This invention discloses a voltage generator circuit having a voltage regulator and a voltage generator for supplying voltage to a load. The voltage regulator is powered by a power source which supplies a first voltage level and the voltage regulator provides a regulated output at a second voltage level lower than the first voltage level. The voltage generator receives power from the regulated output and provides a multiplied output having a third voltage level. Therefore, any level of voltage between the first voltage level and the third voltage level is available to the load circuit. Since the voltage regulator supplies the voltage generator with power at a regulated level, the voltage level applied to the muliplier may be adjusted for conserving power.

Abstract: A method of preparing green ceramic tapes, comprising adding to 100 parts by weight of a fine ceramic powder, 2 to 15 parts by weight, in terms of its resin content, of a binder mixture consisting of an aqueous polyurethane and a water-soluble acrylic resin, the amount of said water-soluble acrylic resin ranging from 10 to 1500 parts by weight per 100 parts by weight of said aqueous polyurethane in said binder mixture, adding a small amount of a dispersing agent to the mixture followed by a sufficient amount of water, kneading the resultant mixture for a time sufficient to prepare an aqueous slip, forming a tape in a known manner from said aqueous, and then drying the green tape obtained.

Abstract: Green ceramic tapes are prepared which comprise a finely divided ceramic powder and a water-compatible polyurethane resin binder. The green tapes are prepared by casting a water-based slip containing the ceramic powder and the water-compatible polyurethane resin binder in the form of the tape and then drying the formed tape. The drying is preferably conducted in two stages, in the first of which a relatively humid atmosphere is maintained.

Abstract: An element of a dual-in-line ceramic package such as a substrate or cover provided with a layer of sealing glass is prepared by forming powdered low-melting sealing glass into a shape conforming to that of the element, compressing and sintering the shaped powdered glass to form a solid sintered sealing glass preform, applying the preform to the surface of the element, and fusing it thereto by heating the assembly.
