摘要:
A fluorine-containing thermosetting resin having a three-dimensional crosslinking structure is obtained by polymerizing a bismaleimide compound having the formula, ##STR1## wherein Rf is fluorine, CF.sub.3, C.sub.2 F.sub.5 or C.sub.3 F.sub.7. The resin is excellent in moldability, thermal resistance and electric properties, has a low dielectric constant, is hence suitable as a molding material and can be used for molding materials, wiring boards, layer insulation films of LSI, etc.

摘要:
A process is provided for the formation of a conductive circuit pattern on a base metal formed on a substrate. On the base metal, a plating resist is first provided in a pattern corresponding to the circuit to be formed and a circuit pattern is then formed by plating. The plating resist is treated with a stripper and then with a stripping residue remover to cut off chemical bonds in the resist by a dehydrating decomposition reaction. The base metal is treated with an etchant for the base metal, whereby any resist residue still remaining after the treatment with the stripping residue remover is removed and the base metal are etched at areas which were covered by the plating resist.

In a V-type multi-cylinder engine, a first fuel supply conduit is connected to fuel-injection valves in a first throttle body group corresponding to the first bank, and a second fuel supply conduit is connected to fuel injection valves in a second throttle body group corresponding to the second bank. A pair of first and second side plates connect adjacent ends of the first and second throttle body groups together. A distance between respective throttle bodies located in two ends of the first throttle body group is set shorter than a comparable distance between the throttle bodies located in two ends of the second throttle body group. A joint part for connectively receiving the fuel hose is provided at an end of the first fuel supply conduit in a way that the joint part is arranged between the two side plates.
