摘要： Disclosed is an electronic circuit device in which the solder (14) connecting lead pins (6) to the ceramic substrate (2) has a melting point of 356.degree. C. to 450.degree. C. and has a tensile strength being low in such an extent that a thermal contraction stress generated in a cooling process of the solder (14) from the melting point thereof is low and the substrate (2) does not break. The solder (14) is a Au-Ge alloy containing 10-15 wt % of Ge. Electronic circuit devices, which employ the above solder (14) in the connections, are free from damages in the ceramic wiring substrate (2) due to the bonding. Further, when the electronic circuit device undergoes a series of assembly processes after the above bonding, such solder (14) does not melt, and wettability of such solder (14) is favorable.

摘要： A magnetic bubble memory module having a rectangular core shaped like a picture frame providing windings on respective two pairs of opposite sides, at least one magnetic bubble memory chip disposed in an area surrounded by the core, a flexible substrate having a chip-loading section for loading the magnetic bubble memory chip thereon and having four corners for leading out lead wires connecting signal lines and driving lines of the chip. A revolving magnetic field-confining case accommodates the core, the chip and the flexible substrate and enables the lead wires of the flexible substrate at the corners of the chip-loading section to be drawn out therethrough.

摘要： A piece gun for spraying includes a base body. A trunk portion is provided with a storage area for containing a coating liquid. The trunk portion is positioned within the base body. A head portion is connected to the trunk portion. The head portion is provided with a writing member for discharging the coating liquid. A first air passage surrounds at least the head portion of the trunk portion. A second air passage is operatively connected to a source of high pressure fluid. A switching valve includes an operational member for manual actuation and a working member operatively connected to the operational member. The working member initially operates the switching valve to connect the second air passage to the atmosphere during an early stage of operation of the operational member. The working chamber communicates the second air passage with the first air passage during a latter stage of operation.

摘要： A litz wire comprises three or more insulated strands consisting essentially of an inner conductor and an outer insulating layer on said conductor. The strands are twisted symmetrically with respect to the center line of the wire, so that a current density distribution in the litz wire becomes uniform. Three or more such litz wires are twisted to form a composite litz wire. The composite litz wires are suitable for use in a high-frequency coil.
