摘要： A central portion of a main face of a package substrate 2 is mounted with a memory chip 1 using face down bonding by a flip chip bonding system. Further, a plurality of chip condensers 7 are mounted at vicinities of the memory chip 1. A clearance between a main face (lower face) of the memory chip 1 and a main face of the package substrate 2 is filled with underfill resin (seal resin) 10 constituting a seal member for achieving protection of connecting portions and for relaxation of thermal stress. An outer edge of the underfill resin 10 is extended to an outer side of the memory chip 1 and covers entire faces of the chip condensers 7 mounted at vicinities of the memory chip 1.

摘要： A toothed belt particularly suitable for use in general industrial machineries includes a cured rubber belt body, a tensile member embedded in the belt body, and a tooth fabric adhered to the surface of teeth of the belt body. The belt body is formed primarily from a vulcanizable rubber composition containing hydrogenated nitrile rubber and zinc polymethacrylate. The zinc polymethacrylate and the hydrogenated nitrile rubber are blended together in a ratio of from 22:78 to 45:55 parts by weight. To the vulcanizable rubber composition, a vulcanizing agent comprised of peroxide and a reinforcer comprised of carbon black are added, and a mixture is vulcanized and pressed or otherwise molded to form the afore-said cured rubber belt body with the tensile member embedded therein. The tensile member is made of high-strength glass fibers. The glass fibers preferably have a resorcin-formalin-latex layer and an overcoat layer both formed thereon.

摘要： As the semiconductor chip is large-sized, highly integrated and speeded up, it becomes difficult to pack the semiconductor chip together with leads in a package. In view of this difficulty, there has been adopted the package structure called the “Lead-On-Chip” or “Chip-On-Lead” structure in which the semiconductor and the leads are stacked and packed. In the package of this structure, according to the present invention, the gap between the leading end portions of the inner leads and the semiconductor chip is made wider than that between the inner lead portions except the leading end portions and the semiconductor chip thereby to reduce the stray capacity, to improve the signal transmission rate and to reduce the electrical noises.

摘要： A skew-toothed belt includes tension members, a tooth portion, and a back portion. The tooth portion and the back portion are located on opposite sides of an array of the tension members. The tooth portion is covered with a tooth cloth, which is arranged such that the weft thread extends substantially perpendicular to the tooth trace direction of each skewed tooth. A method for manufacturing the skew-toothed belt includes the steps of: cutting an elongated tooth cloth material obliquely to the weft direction so as to obtain a tooth cloth sheet; bonding the opposite end portions of the tooth cloth sheet extending along the warp together to form a cylindrical tooth cloth; fitting the cylindrical tooth cloth onto a cylindrical die on which tooth-profiled grooves are formed; sequentially winding the tension members and an unvulcanized rubber compound sheet onto the fitted cylindrical tooth cloth; subjecting the resultant assembly to forming and vulcanization in a pressure chamber; and cutting the resultant cylindrical body into annular toothed belts, each having a predetermined width.

摘要： As the semiconductor chip is large-sized, highly integrated and speeded up, it becomes difficult to pack the semiconductor chip together with leads in a package. In view of this difficulty, there has been adopted the package structure called the "Lead-On-Chip" or "Chip-On-Lead" structure in which the semiconductor and the leads are stacked and packed. In the package of this structure, according to the present invention, the gap between the leading end portions of the inner leads and the semiconductor chip is made wider than that between the inner lead portions except the leading end portions and the semiconductor chip thereby to reduce the stray capacity, to improve the signal transmission rate and to reduce the electrical noises.

摘要： A hydroponic nutrient solution control system capable of performing the nutrient solution control automatically, accurately, effectively, and efficiently. In the system, the supplies of the acid nutrient ion ingredient solutions and the alkali nutrient ion ingredient solutions from the acid solution tanks and the alkali solution tanks to the nutrient solution tank are controlled according to the pH measured by the pH meter and the ion concentrations measured by the ion analyzer. The system may also controls the supplies of the high concentration nutrient solutions and the water from the high concentration nutrient solution tanks and the water supply according to the electrolytic conductivity measured by the electrolytic conductivity meter.
