  • Patent number: 6490833
    Abstract: A weather strip is attached to the periphery of an organic glass plate. The organic glass plate is supported by a slide panel. A space is defined between the weather strip and an end face of the periphery of the organic glass plate. The space accommodates thermal expansion of the organic glass plate. A tube is located at a corner of the weather strip. Foreign matter trapped in the space moves from the space to the tube and then is discharged from the space.

  • Patent number: 6400254
    Abstract: A keyhole is formed on an operating knob installed on the front surface of a rotary switch. The rotary switch can therefore be operated by inserting into the keyhole an electronic key having a long and narrow shape and then turning the operating knob. As a result, operations for an engine start using the electronic key are the same as those using a conventional key.

  • Patent number: 6139076
    Abstract: An unlock mechanism for a foldable rear seat back which prevents damage to an unlocked state indicator and a front seat. A warning bezel (24) is slidingly fit in a fixed bezel (22) which is fixed to an upper surface (10A) of a rear seat back (10). A first link (32) engages with the warning bezel (24). The first link (32) is connected to a bell crank (38). The bell crank (38) is urged upward by a spring (46). A pin (54), which is provided upright at a latch (16), is movably inserted into a slot (52) which is formed in an open link (50) which is engaged with the bell crank (38). Accordingly, in an unlocked state, when the warning bezel (24) is pressed into the fixed bezel (22), the first link (32) moves downward against urging force of a spring (46), and the warning bezel (24) is accommodated in the fixed bezel (22).

  • Patent number: 5358621
    Abstract: In a semiconductor device having multi-layer lead conductors, lead conductors of each layer and through connections are generated by electro chemical plating process. A flat and smooth surface is provided for each layer on which lead conductor base patterns are formed. Plating lead conductors on a layer and plating through connections are executed in a separate process. And, in these platings, electrolytic current is so controlled that the growth of plating is always from the base of the plating.

  • Patent number: 5087856
    Abstract: A discharge electrode for a charger has a thin wire or core made of stainless steel or electrolytically polished tungsten, and a coating provided on the thin line. To form the coating, amorphous alloy containing tantalum, niobium, zirconium, titanium or similar element belonging to the same group on the periodic table is deposited on the thin wire by sputtering, CVD (Chemical Vapor Deposition) or similar technology. The content of tantalum in the amorphous alloy is selected to be 10 at % to 70 at %.
