摘要： PROBLEM TO BE SOLVED: To make detectable the temp./oxygen concn. by a convenient method, without using complicated electric wirings or measuring circuits by constituting a detector for detecting signals from a specified ceramic sintered compact.
SOLUTION: E.g., 6 sheets of ceramic sintered compact 1 formed in specified dimensions, contg. zinc oxide 80 mol% or more, are adhered onto an alumina board 3 with an inorg. adhesive 2 to form the furnace atmosphere detector. The sheets of sintered compact 1 are made by sintering in the air (O concn. 20%) at temps. of 950°C, 960°C, 970°C, 980°C, 990°C, respectively. The furnace atmosphere detector is set in an electric furnace set e.g. at 970°C, the surface of each sintered compact 1 is visually seen after completion of the sintering process. In this time voids or cracks appear on the sintered compact surface at 950°C, 960°C, 970°C, and if no change appears on the sintered compact at 980°C, 990°C, the furnace temp. is lower than 980°C and higher than 970°C. When the temp. must be known at a more fine resolution, the furnace temp. can be estimated at an accuracy within about 2°C from the change of the crystal grain size.

摘要： PROBLEM TO BE SOLVED: To provide a ceramic core for forming a cooling passage of a gas turbine blade, which can successfully secure dimensional (shape) accuracy while maintaining characteristics as a core.SOLUTION: An oxide which does not form a reaction product with molten silica, has a low melting point and promotes a reaction between silica particles is added to a core basic composition mainly composed of molten silica. The core can be manufactured at a temperature lower than in the past due to the sintering-promoting effect of the added component, the degree of dimensional contraction is reduced due to the low-temperature sintering, and the dispersion between sample sites is also largely reduced. When this ceramic core is used, the yield of a precise cast product using a wax model can be improved since it has high dimensional (shape) accuracy.

摘要： A resin-encapsulated semiconductor package and a packaging structure, make it possible to provide for a high density mounting arrangement. Specifically, outer leads protrude from the two long sides of a rectangular package. The inner leads in the package, connected to the outer leads protruding from one long side, are connected through wires to the bonding pads of a semiconductor chip encapsulated in the package, whereas the inner leads in the package, connected to the outer leads protruding from the other long side, are in an electrically floating state in the package. The semiconductor packages are arranged in a direction on a card-shaped mounting board, and the opposed outer leads of adjoining semiconductor packages are electrically connected by wiring on the mounting board. The wirings are laid below the semiconductor packages so that they extend generally linearly.
