  • Patent number: 5810635
    Abstract: A ceramic discharge vessel (8) for a high-pressure discharge lamp has a pin-like feedthrough (10) inserted in a plug (11) made from a composite material. The feedthrough (10) has been sintered directly into the plug (11) and is additionally sealed by covering the area, surrounding the feedthrough, of the plug's surface facing away from the discharge volume with a ceramic sealing material (7a).

  • Patent number: 5747762
    Abstract: An oscillation switch consists of a pair of ring-shaped electrodes each having an inner surface coaxially provided with a projection and spaced apart at a predetermined distance, and balls arranged in a space formed between the electrodes so that the balls engage the projections to electrically connect the electrodes together when oscillation or lateral sliding occur. A portable electrically driven machine provided with the oscillation switch has the oscillation switch provided on a frame and has a structure which stops a tool rotating motor and a feed motor by interrupting the electric power supply to a control unit of the electric tool. The use of the oscillation switch allows the tool rotating motor or the feed motor to stop as soon as lateral sliding or oscillation starts to occur or when the portable electrically driven machine starts to fall down even if the portable electrically driven tool takes any posture.

  • Patent number: 5637960
    Abstract: To provide a tight seal for a fill bore in the wall or an end plug of a dharge vessel for high-pressure discharge lamps, a fill bore is provided either through the wall--in the region of the plug--or through a plug, and the fill bore is then closed by a stopper in combination with a melt sealing material, which is so chosen that the sealing material and plug-like member combination provide a minimum of sealing material exposed to the fill in the discharge volume. The fill in the discharge volume of the discharge vessel is ionizable and, for example containing halides, is highly corrosive to the sealing material. The lamp can be made by inserting a stopper into the filling bore, applying, with the stopper in place in the filling bore, sealing material to the outer end of the filling bore, and heating the portion of the discharge vessel to liquefying temperature of the sealing material to liquefy the sealing material and hence close off the fill bore.

  • Patent number: 5592049
    Abstract: A high pressure discharge lamp having an extended life includes a discharge vessel 8, and a feedthrough 10 extending through a plug 11. A directly sintered connection is formed between the feedthrough 10 and the plug 11 wherein sealing material 7 is provided covering the area surrounding the feedthrough on the outer surface of the plug 11. The plug 11 is formed of a composite material whose thermal expansion coefficient lies between that of the ceramic vessel and of the metal feedthrough.
