  • Process for manufacturing gas flow unit
    Patent number: 5293922
    Abstract: A metal is attached on a passage-forming core by electrocasting to provide a primary metal layer. A plurality of grooves are formed on the primary metal layer and are filled with filler of low melting point. A metal is attached on the primary metal layer by electrocasting to provide a secondary metal layer. Openings are formed on the secondary metal layer adjacent to its opposite ends so as to communicate with the grooves. The filler in the grooves is melted to provide a plurality of coolant passages. The openings are filled with manifold-forming cores made of filler with low melting point. A metal is attached on the manifold-forming cores by electrocasting to provide tertiary metal layers. Through holes are formed on the tertiary metal layers. The passage-forming core is dissolved and the manifold-forming cores are melted to provide a gas passage and manifolds.

  • Method of continuously soldering small elements arranged generally in a line by a concentrated radiant energy source
    Patent number: 4034180
    Abstract: Continuous soldering of small elements along a line is achieved by a radiant beam spot lamp which moves intermittently along the line, and radiant energy is supplied only while the lamp is stopped to form partially overlapped heating zones.
