  • Patent number: 5086337
    Abstract: This invention relates to a connecting structure for electrically connecting an electronic part such as an LSI chip to a substrate, its production method and an electronic device using the former. The present invention is particularly useful for connecting electrically a plurality of chips, for which an absorption function of the difference of thermal expansion in a horizontal direction and capability of displacement in a vertical direction are requisite, to a substrate. Moreover, the connecting structure of the present invention can simplify the fabrication process, has high reliability and can be applied to high performance electronic appliances and apparatuses such as electronic computers.

  • Patent number: 4922377
    Abstract: This invention relates to a module which mounts a plurality of semiconductor devices and to a module substrate that interconnect the semiconductor devices.This invention has the testing and engineering change pads on the underside of the substrate. This arrangement results in the advantages of: providing a sufficient area for the testing and engineering change pads; improving the package density of semiconductor devices, which in turn leads to higher computation speed; and eliminating the need for a special cooling system during the module testing, simplifying the process of testing. Furthermore, since the signal joint terminals to the semiconductor chips are provided on the surface of the substrate on which the semiconductor chips are mounted and since the power bus joint terminals are provided around the chips on the semiconductor chip-mounting surface of the substrate, it is possible to realize a high density package with high reliability.

  • Patent number: 4715673
    Abstract: An optical switch having a small number of optical connections includes a substrate in which are provided a first light path for conducting optical signals and a second light path consisting of a photosensitive element and light emitting element in pairs. An optical fiber cable is interrupted by the substrate, and optical signals in the fiber cable are transmitted through the first light path or intervened by an electrical system through the second light path in response to the switching movement of the substrate.

  • Patent number: 4638443
    Abstract: A gas detecting apparatus incorporates a number of gas detecting elements which react with a variety of gases and exhibit gas sensitivities differing from one another in dependence on the gas species. The detection patterns obtained by quantitizing the detection outputs of the gas detecting elements are compared with a plurality of standard patterns prepared previously for assumed combinations of gas species and concentrations thereof. On the basis of the standard pattern which is same or most similar to the detection pattern, the gas species is identified.

  • Patent number: 4598167
    Abstract: A multilayered ceramic circuit board, formed by sintering together a plurality of unit ceramic circuit boards, wherein each unit ceramic circuit board includes a ceramic layer, a patterned electrically conductive layer and through hole conductors formed in the ceramic layer for connecting the patterned electrically conductive layers of the respective unit ceramic circuit boards to form a predetermined wiring circuit. The patterned electrically conductive layers and the through hole conductors have a coefficient of thermal expansion which is greater than the coefficient of thermal expansion of the ceramic layers, wherein the difference between the coefficients of thermal expansion is selected to be less than 100.times.10.sup.-7 /.degree.C., and the through holes have decreased pitch. The conductive layers and conductors can be formed of a metal such as gold, silver or copper, with a low softening point glass filler to reduce the coefficient of thermal expansion of the conductive layers and conductors.

  • Patent number: 4586143
    Abstract: A gas detecting apparatus is disclosed in which detection outputs from a plurality of semiconductor gas detecting elements different in gas detection characteristic from each other and previously-obtained characteristic values of the semiconductor gas detecting elements for a mixed gas are subjected to operational processing to detect one or more specified constituent gases contained in the mixed gas, and in which when the specified constituent gas is detected, the detection information is announced by some means, and also the supply of gas is stopped or a supply gas is diluted.

  • Patent number: 4457161
    Abstract: A gas detection device and a method for detecting a gas where gas information including concentrations of gas components in a mixed gas, concentration, presence of specific gas components and the like is detected by measuring, e.g., the output voltages of a plurality of gas sensors having different gas selectivities. The gas selectivities, as a characteristic constant of the specific gas sensor, was previously determined. The measured output voltages and gas selectivities are then used for solving plural simultaneous equations for gas concentrations.
