Abstract: PURPOSE:To firmly fix a lead pin without any problem regarding a positional accuracy of a hole and a uniting operation between a metal sheet and an insulating sheet by a method wherein also the inside of the hole is coated uniformly with crystallized glass by using an electrophoretic electrodeposition method, this coating is baked, Ni is used to form a first metal layer and an alkaline etchant is used to etch a part other than a circuit pattern. CONSTITUTION:An enamel substrate where up to the inside of a through hole has been coated with crystallized glass containing BaO; SiO2, MgO and B2O3 by an electrophoretic electrodeposition method and this coating has been baked is used for a metal substrate having a through hole into which a lead pin is inserted. An Ni metal layer is formed up to the inside of the through hole by an electroless plating method. Then, a plated resist is formed, by using a photolithographic method, on the surface of the metal layer excluding a part used to form a circuit pattern. Then, an etching resist is formed on the surface of the patterned metal layer where the plated resist is not formed. Then, the plated resist is removed; the metal layer is removed by using an alkaline etchant at a pH of 8 to 13.

Abstract: PURPOSE:To prevent the generation of knocking and the deterioration of the engine faculty by cutting off an intercooler bypass and supplying the intake cooled by an intercooler to an engine when the engine is in high load and high speed revolution even if the engine is at a warming temperature or below. CONSTITUTION:Each compressor of large-sized turbocharger 15 and small-sized turbocharger 16, intercooler 17, and a throttle valve 18 are arranged in this order from the upstream side in an intake pipe 12, and an intercooler bypass passage 101 is installed, making a detour around the intercooler 17, and a bypass valve 103 is interposed midway. The intercooler bypass valve 103 is valve-- opening-controlled according to the engine temperature such as the cooling water temperature, when the engine temperature is low.
