  • Patent number: 8671798
    Abstract: An annular isolator (68, 70) is disposed in an open ended bore (66) of a support body (58) and surrounds an end fitting (26, 28) for attenuating vibrations therebetween. A cap (74) is disposed on the support body (58) to close the open ended bore (66). An inflexible compression ring (76) is sandwiched axially between the isolator (68, 70) and the cap (74) and in abutting engagement with a stop (78) to limit compression of the isolator (68, 70) from the cap (74). The compression ring (76) is inserted into the bore (66) prior to molding the cap (74) to limit compression of the isolator (68, 70) during fabrication.

  • Patent number: 8312788
    Abstract: A motion transmitting remote control assembly (20) of the type for transmitting motion in a curved path by a flexible core element (22) in a conduit (24) is secured to a support structure (76) having a U-shaped slot. A support body (66) defines a groove (84) having first and second legs (86, 88) for abutting parallel edges (78) of the U-shaped slot, and a bottom leg (90) connecting the first and second legs (86, 88) for abutting a bottom edge (80). Slider arms (94) movably supported within female guides (92) are urged against snap-in retainers (102) by biasing spring members (104) establishing a locking position. A pair of locking tabs (106) projecting from the slider arms (94) into the groove (84) engage notches (82) in the parallel edges (78). An inclined face (112) is defined along the lower surface (112) of the locking tabs (106) for wedging engagement with the parallel edges (78) of the U-shaped slot to move the slider arms (94) axially to an insertion position.

  • Patent number: 7597027
    Abstract: A motion transmitting remote control assembly (20) of the type for transmitting motion in a curved path by a flexible core element (22) in a conduit (24) is secured to a support structure (76) having a U-shaped slot. A coupling body (36) surrounds the core element (22) and is surrounded by a support body (66) for attachment to the support structure (76). A flange (42) extends radially about the coupling body (36) and is disposed axially between a first and second ends (38, 40) of the coupling body (36). First and second isolators (52, 54) surround the coupling body (36) on opposite sides of the flange (42) and include first and second ribs (63, 64) projecting radially from first and second head portions (61, 62) of the isolators (52, 54). The first and second ribs (63, 64) contact an inner radial surface (122) of the support body (66) thereby spacing the first and second head portions (61, 62) from the support body (66).

  • Patent number: 7373535
    Abstract: The present invention relates to an electric power saving apparatus wherein light energy is irradiated to a semiconductor device, with the light energy emitted when a voltage is supplied to a transmission line, such that the wavelengths of the electrons on the transmission line, along which a load-driving current flows are elongated, and the spin motions and vibration states of the electrons are stabilized, thereby reducing the collision of electrons in order to reduce the loss of energy, and wherein the light energy irradiated to the semiconductor device is continuously supplied thereto, by the use of an infrared ray emitting diode during operation, thereby maintaining the power saving effects with stability and continuity.

  • Patent number: 6448588
    Abstract: An insulated gate bipolar transistor having a high breakdown voltage in a reverse blocking mode and a method for fabricating the same are provided. The insulated gate bipolar transistor includes a relatively low-concentration lower buffer layer and a relatively high-concentration upper buffer layer. The low-concentration lower buffer layer contacts a semiconductor substrate having a high concentration of first conductivity type impurities used as a collector region, and the high-concentration upper buffer layer contacts a drift region of a second conductivity type. The conductivity type of the upper buffer layer is second conductivity type impurities, and the conductivity type of the lower buffer layer is substantially intrinsic, or first conductivity type impurities, or second conductivity type impurities. According to the present invention, due to the high-concentration upper buffer layer, the thickness of the drift region can be reduced, and during a forward continuity, a switching speed can be improved.
