A valve device for an internal combustion engine is provided with two flange portions, each of which is arranged at the outer periphery of a valve and has a larger outer diameter than a shaft. Annular valve-side end surfaces of the flange portions obstruct water flowing toward bearings and the inner surface of a cylindrical portion of a house along the surface of the shaft. Thus, water can be restricted from flowing into annular gaps between the shaft and the housing and annular gaps between the shaft and bearing members. Accordingly, water is not frozen in the annular gaps, thus restricting the shaft and the valve from freezing/sticking.

A signal transmission apparatus is disclosed for setting delay amounts based on an operational speed. At least some of a plurality of rectangular wave signals transmitted in parallel are individually delayed by a plurality of signal delaying means for different time periods from one another in order to prevent the occurrence of noise. At this point, the delay time in the plurality of signal delaying means are set by time varying means based on the operational speed of a digital circuit which outputs digital data as the rectangular wave signals.

A valve timing controller has a spiral spring biasing a vane rotor in an advance direction. An inner end and an outer end of the spring are respectively engaged with an engage groove and an engage pin in such a manner that a center of a most inner imaginary circle passing through a center line of the wire is apart from a center of a most outer imaginary circle passing through both the center line of the wire and an engage point between the inner end and the engage groove. The most outer imaginary circle is eccentric to the most inner imaginary circle by a specified amount.

[Problem] The present invention provides a manufacturing method and apparatus of an organic resin coated metal sheet which can surely remove resin portions projecting from both edges of a metal sheet.[Means for Resolution] A long strip metal sheet 1 is continuously fed using a metal-sheet supply means 13. Temperatures of edge portions 1a, 1b of the metal sheet 1 and a temperature of an approximately central portion 1c of the metal sheet 1 are respectively measured using a metal-sheet temperature measuring means 7 arranged directly upstream of lamination rolls 10. Respectively measured temperature values are inputted to a heating temperature control means 14. An output value calculated by the heating temperature control means is inputted to a metal sheet center portion heating means 3 arranged directly upstream of the T-die 8 so as to heat a widthwise approximately center portion of the metal sheet 1 to a first temperature by the metal sheet center portion heating means 3. Output values calculated by the heating temperature control means 14 are fed to metal sheet edge portion heating means 5 arranged directly upstream of the T-die 8 so as to heat the widthwise edge portions of the metal sheet 1 to a second temperature higher than the first temperature by the metal sheet edge portion heating means 5. A resin film is extruded to pre-rolls 9 such that the resin film projects from both widthwise edge portions of the metal sheet 1. The resin film is applied to the metal sheet 1 by sandwiching and pressure-bonding the metal sheet 1 and the resin film between a pair of lamination rolls 10. Resin portions 2a in a semi-molten state and projecting from both edge portions of the metal sheet are removed by press cutting.
