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 connection method and connection apparatus for connecting long belt-shaped non-oriented resin films that are continuously advanced. A leading resin film and a trailing resin film can be connected while processing in a following step is continuously performed. The tip end of a trailing resin film (22) is joined and connected to a leading resin film {11), and then a portion, immediately after the connected position, of the leading resin film is heated to a predetermined temperature range and cut.

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.

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 manufacturing method and apparatus of an organic resin coated metal sheet is provided. Temperatures of edge portions of the metal sheet and a temperature of an approximately central portion of the metal sheet are respectively measured using a metal-sheet temperature measuring device arranged directly upstream of lamination rolls. Respectively measured temperature values are inputted to a heating temperature controller, and output values calculated by the heating temperature controllers are inputted to a metal sheet center portion heater and the metal sheet center portion heater, respectively, to control the heating of a widthwise approximately center portion and edge portion, respectively, to a first and second temperature, respectively, the second temperature being higher than the first. A resin film is extruded to pre-rolls and is sandwiched and pressure-bonding to the metal sheet between a pair of lamination rolls. Resin portions projecting from both edge portions are then removed.

The present invention aims at the continuous and stable production of an organic-resin-coated metal sheet in producing the organic-resin-coated metal sheet by an extrusion method using a laminating roll which can prevent resin portions (ear portions) protruding from the metal sheet being wound around shaft portions of the laminating roll. Using a laminating roll in which a width (A) of a region thereof coated with a lining material satisfies a relationship of 0≦A−B≦20 mm with respect to a width (B) of the metal sheet, a thermally melted organic resin is extruded and is applied to the metal sheet such that end portions of the organic resin in the widthwise direction protrude from outer portions of the laminating roll applied with the lining material, and the resin portions in a semi-molten state which protrude from respective edges of the metal sheet are removed by press-cutting.
