  • Patent number: 6093889
    Abstract: A mounting socket for a semiconductor package has socket leads that contact the semiconductor package's external leads. The semiconductor package has a package body surrounding a semiconductor chip, as well as internal and external leads. The external leads are formed in an ingot shape and project outwardly from the package body, and are adapted to connect with the socket leads or external terminals. The external leads contact external walls of the package body, thereby preventing undesired bending or breaking of the leads when the package is handled. Fixing and reworking of the package in the socket is easy, since the semiconductor package is inserted into grooves in the socket. It is possible to stack-mount or side-by-side-mount the package, depending on the socket shape, thus improving socket density and making the arrangement suitable for miniaturization.

    Abstract: A small-sized gas ignition device comprising a self-oscillation circuit, a piezo-electric transformer which steps up the output of the self-oscillation circuit, a capacitor which accumulates the output voltage of the piezo-electric transformer, and a discharging gap which is connected in parallel with the capacitor and is adapted to discharge the accumulated voltage for performing gas ignition. With this device gas ignition is obtained with certainty by single operation requiring only a light touch.
